Machine-learning models vulnerable to undetectable backdoors ‱ The Register

https://www.schneier.com/crypto-gram/archives/2022/0515.html#cg1

New paper: “Planting Undetectable Backdoors in Machine Learning Models“:

Abstract: Given the computational cost and technical expertise required to train machine learning models, users may delegate the task of learning to a service provider. We show how a malicious learner can plant an undetectable backdoor into a classifier. On the surface, such a backdoored classifier behaves normally, but in reality, the learner maintains a mechanism for changing the classification of any input, with only a slight perturbation. Importantly, without the appropriate “backdoor key”, the mechanism is hidden and cannot be detected by any computationally-bounded observer. We demonstrate two frameworks for planting undetectable backdoors, with incomparable guarantees.

First, we show how to plant a backdoor in any model, using digital signature schemes. The construction guarantees that given black-box access to the original model and the backdoored version, it is computationally infeasible to find even a single input where they differ. This property implies that the backdoored model has generalization error comparable with the original model. Second, we demonstrate how to insert undetectable backdoors in models trained using the Random Fourier Features (RFF) learning paradigm or in Random ReLU networks. In this construction, undetectability holds against powerful white-box distinguishers: given a complete description of the network and the training data, no efficient distinguisher can guess whether the model is “clean” or contains a backdoor.

Our construction of undetectable backdoors also sheds light on the related issue of robustness to adversarial examples. In particular, our construction can produce a classifier that is indistinguishable from an “adversarially robust” classifier, but where every input has an adversarial example! In summary, the existence of undetectable backdoors represent a significant theoretical roadblock to certifying adversarial robustness.

Zero-day bug in uClibc library could leave IoT devices vulnerable to DNS poisoning attacks

A zero-day vulnerability in uClibc and uClibc-ng, a popular C standard library, could enable a malicious actor to launch DNS poisoning attacks on vulnerable IoT devices.

The bug, tracked as ICS-VU-638779, which has yet to be patched, could leave users exposed to attack, researchers have warned.

DNS poisoning

In a DNS poisoning attack, the target domain name is resolved to the IP address of a server that’s under an attacker’s control.

This means at if a malicious actor were to send a ‘forgotten password’ request, they could direct it to their own email address and intercept it – allowing them to change the victim’s password and access their account.

For an IoT device, this attack could potentially be used to intercept a firmware update request and instead directing it to download malware.

The DNS poisoning vulnerability was discovered by researchers at Nozomi Networks, who revealed that the issue remains unpatched, potentially exposing multiple users to attack.

Nozomi Networks states that uClibc is known to be used by major vendors such as Linksys, Netgear, and Axis, or Linux distributions such as Embedded Gentoo. uClibc-ng is a fork specifically designed for OpenWRT, a common operating system for web routers.

The library maintainer was unable to provide a fix, according to Nozomi. The researchers said they would refrain from sharing technical details or listing vulnerable devices until a patch is available.

“It’s important to note that a vulnerability affecting a C standard library can be a bit complex,” the team wrote in a blog post this week.

“Not only would there be hundreds or thousands of calls to the vulnerable function in multiple points of a single program, but the vulnerability would affect an indefinite number of other programs from multiple vendors configured to use that library.”

Nation-state Hackers Target Journalists with Goldbackdoor Malware

Category: Hacking,Information Security,MalwareDISC @ 10:20 pm

A campaign by APT37 used a sophisticated malware to steal information about sources , which appears to be a successor to Bluelight.

Sophisticated hackers believed to be tied to the North Korean government are actively targeting journalists with novel malware dubbed Goldbackdoor. Attacks have consisted of multistage infection campaign with the ultimate goal of stealing sensitive information from targets. The campaign is believed to have started in March and is ongoing, researchers have found.

Researchers at Stairwell followed up on an initial report from South Korea’s NK News, which revealed that a North Korean APT known as APT37 had stolen info from the private computer of a former South Korean intelligence official. The threat actor–also known as Ricochet Collima, InkySquid, Reaper or ScarCruft—attempted to impersonate NK News and distributed what appeared to be a novel malware in an attempt to target journalists who were using the official as a source, according to the report.

NK News passed details to Stairwell for further investigation. Researchers from the cybersecurity firm uncovered specific details of the malware, called Goldbackdoor. The malware is likely a successor of the Bluelight malware, according to a report they published late last week.

“The Goldbackdoor malware shares strong technical overlaps with the Bluelight malware,” researchers wrote. “These overlaps, along with the suspected shared development resource and impersonation of NK News, support our attribution of Goldbackdoor to APT37.”

APT37 was previously seen using Bluelight as a secondary payload last August in a series of watering hole attacks against a South Korean newspaper that used known Internet Explorer vulnerabilities.

As Stairwell researchers noted, journalists are “high-value targets for hostile governments,” and often the target of cyber-espionage attacks. In fact, one of the biggest security stories of last year was various governments’ use of the NGO Group’s Pegasus spyware against journalists, among other targets.

“[Journalists] often are aggregators of stories from many individuals–sometimes including those with sensitive access,” Stairwell researchers wrote. “Compromising a journalist can provide access to highly-sensitive information and enable additional attacks against their sources.”

Free Infographic: What is ransomware and how can I protect my business?

Category: Information SecurityDISC @ 9:10 am

Ransomware is a type of malicious program that demands payment after launching a cyber attack on a computer system. This type of malware has become increasingly popular among criminals, costing organizations millions each year.

Security experts recognise that ransomware is one of the fastest-growing forms of cyber attack. Its prevalence and reach was emphasised when WannaCry, and more recently, NotPetya, exploited a flaw in Microsoft’s SMB software and spread rapidly across networks, locking away files.

How vx-underground is building a hacker’s dream library

How vx-underground is building a hacker’s dream library

Editor’s Note: When malware repository vx-underground launched in 2019, it hardly made a splash in the hacking world. “I had no success really,” said its founder, who goes by the online moniker smelly_vx.

But over the last couple of years, the site’s popularity has soared thanks in part to its robust Twitter presence that mixes breaking cybersecurity news with memes. The site now bills itself as “the largest collection of malware source code, samples, and papers on the internet,” with about 35 million samples overall.

vx-undergound operator smelly_vx recently talked to Recorded Future analyst and product manager Dmitry Smilyanets about the site’s goals, finances, and plans for the future. The interview, which was conducted over email in English, has been lightly edited for clarity.

Dmitry Smilyanets: I would like to start from the very beginning — please introduce yourself.

smelly_vx: Hi. I am “smelly__vx“. I am the creator of vx-underground and the guy who runs/maintains a good portion of vx-underground’s website and the vx-underground Twitter account.

I am in my early 30s. I have a wife. I have a dog. I don’t think I can say anything else which is interesting or important.

DSTell me about the site’s background — how did it start, how did you build it into what it is today?

VX: About vx-underground — it was created to act as the successor to the legendary vxHeaven (created by the Ukrainian dude herm1t). When I was a teenager I discovered vxHeaven and learned tons from it. It was an invaluable asset. Around 2017 or so, when I was a software engineer, I got tired of writing malware (as a hobbyist) by myself.

I began looking for vxHeaven, or whatever it had become. I was unable to find anything, to my disappointment, and one day on some random IRC server I discovered, I was conveying my disappointment to a guy named Phaith and he said to me, “Well, if you miss it so much, why don’t you make your own?” I thought this was a good idea — why not make my own? And that is precisely what I decided to do. The issue I faced was that my background was in low-level development, I primarily did C/C++ development on the Windows platform. I did not have any skills in web development, web security, system administration, etc. I also did not have any contacts, I had been a “lone wolf” for nearly a decade at this point — I was a “nobody.” However, I decided this shouldn’t be a restraining factor so I bought some random bullshit hosting, purchased the domain name ‘vx-underground’ and got to work.

I officially made vx-underground in May 2019. I had no success really, I did not have a Twitter account or any contacts or any relationships in the information security industry. I made the vx-underground Twitter account in August 2019 and, interestingly, shortly after I made the account I was contacted by a guy named Bane. Bane was a member of a group called ThugCrowd. They had a large follower base on Twitter (20,000+), they had connections, they knew their way around things, blah blah blah. ThugCrowd was very kind to me and supported the idea of a new vxHeaven. They introduced me to some people who also liked the idea of a new vxHeaven.

Unsurprisingly, in October 2019, vx-underground was banned from a lot of web hosts. I had places which housed neo-Nazis, pornography, and gambling, deny my hosting.

Nobody wanted to house malware samples, the only way I was going to get the ability to house malware samples was if I had become a company, and did paperwork and all sorts of bullshit. I did not like this idea. Luckily, and to my surprise, the people over at ThugCrowd introduced me to a group of people behind TCP.DIRECT. They also liked the idea of a new vxHeaven, as the main group of people behind it also had been on the vxHeaven forums ages ago. They assisted me with hosting, handling the web security, etc. This was very beneficial for me because, as TCP.DIRECT will confirm, I am a complete idiot with anything system administrative/web security related.

Following this introduction to TCP.DIRECT, vx-underground had essentially zero restraint. I was able to upload malware samples, malware papers, malware source code, etc. as much as I liked. The only thing I had to do then was add content and be consistent. Along the way I met a guy from the [Commonwealth of Independent States], Neogram, who assisted me with Russian translations and giving me a (metaphorical) tour of the CIS malware scene. This expanded my horizon and gave vx-underground better insight into current malware trends.

All of this happened very quickly, this ‘story’ encapsulates what happened between August 2019 and December 2019.

DSWhat are your mission and goals?

VX: I don’t know. vx-underground is a library, our goal is basically to
 collect malware samples, papers, and code? It exists and that is it. The closest thing to a ‘goal’ we have is simple: “more papers, more samples, more code.” It is as simple as that.

DS: Are you financially motivated? How do you monetize your work? Is it lucrative?

VX: No, we are not financially motivated. vx-underground is fueled by passion and love for the ‘game.’ In 2021 vx-underground made $13,000 all from donations. Every time I tell people vx-underground does not make money I am always greeted with shock and surprise. It appears people are unable to comprehend someone would do something for passion rather than financial gain. This is disappointing.

The importance of understanding cloud native security risks

Category: Cloud computing,Information SecurityDISC @ 10:26 am

In this video for Help Net Security, Paul Calatayud, CISO at Aqua Security, talks about cloud native security and the problem with the lack of understanding of risks to this environment.

A recent survey of over 100 cloud professionals revealed that often businesses lead the charge in cloud, they see the opportunity, they move forward, but more and more critical compute finds its way into these cloud environments, and the security teams start to take notice. Often too late, though.

The survey shows that the awareness is starting to become a problem, and the risks are not fully understood. Organizations need to get ahead of these things. To be able to apply a good cloud native security strategy, understanding the risks is imperative.

FCC adds Kaspersky to Covered List due to unacceptable risks to national security

Category: Antivirus,Information Security,Information WarfareDISC @ 9:53 pm

The Federal Communications Commission (FCC) added Kaspersky to its Covered List because it poses unacceptable risks to U.S. national security.

The Federal Communications Commission (FCC) added multiple Kaspersky products and services to its Covered List saying that they pose unacceptable risks to U.S. national security.

“The Federal Communications Commission’s Public Safety and Homeland Security Bureau today added equipment and services from three entities – AO Kaspersky Lab, China Telecom (Americas) Corp, and China Mobile International USA Inc. – to its list of communications equipment and services that have been deemed a threat to national security, consistent with requirements in the Secure and Trusted Communications Networks Act of 2019.” reads the FCC’s press release.

The Covered List, published by Public Safety and Homeland Security Bureau published, included products and services that could pose an unacceptable risk to the national security of the United States or the security and safety of United States persons.

The US commission also added Chinese state-owned mobile service providers China Mobile International USA and China Telecom Americas to the list. Below is the list of Covered Equipment or Services added on March 25, 2022:

  • Information security products, solutions, and services supplied, directly or indirectly, by AO Kaspersky Lab or any of its predecessors, successors, parents, subsidiaries, or affiliates.
  • International telecommunications services provided by China Mobile International USA Inc. subject to section 214 of the Communications Act of 1934.
  • Telecommunications services provided by China Telecom (Americas) Corp. subject to section 214 of the Communications Act of 1934.

FCC banned Kaspersky security solutions and services supplied by Kaspersky or any linked companies.

“The FCC’s decision to add these three entities to our Covered List is welcome news. The FCC plays a critical role in securing our nation’s communications networks, and keeping our Covered List up to date is an important tool we have at our disposal to do just that. In particular, I am pleased that our national security agencies agreed with my assessment that China Mobile and China Telecom appeared to meet the threshold necessary to add these entities to our list. Their addition, as well as Kaspersky Labs, will help secure our networks from threats posed by Chinese and Russian state backed entities seeking to engage in espionage and otherwise harm America’s interests.” said FCC Commissioner Brendan Carr. “I applaud Chairwoman Rosenworcel for working closely with our partners in the Executive Branch on these updates. As we continue our work to secure America’s communications networks, I am confident that we will have more entities to add to our Covered List.”

In Mid March, the German Federal Office for Information Security agency, aka BSI, recommended consumers uninstall Kaspersky anti-virus software. The Agency warns the cybersecurity firm could be implicated in hacking attacks during the ongoing Russian invasion of Ukraine.

According to §7 BSI law, the BSI warns against the use of Kaspersky Antivirus and recommends replacing it asap with defense solutions from other vendors.

Biden signs cyber incident reporting bill into law

Biden signs cyber incident reporting bill into law

President Joe Biden on Tuesday signed into law a $1.5 million government funding bill that includes legislation mandating critical infrastructure owners report if their organization has been hacked or made a ransomware payment.

Biden signed the legislation during a White House ceremony that was attended by administration officials and top Democratic lawmakers, including including House Speaker Nancy Pelosi (Calif.), Senate Majority Leader Chuck Schumer (N.Y.).

The Strengthening American Cybersecurity Act — which was attached to the spending deal that keeps the federal government open until September — requires that critical infrastructure operators alert the Homeland Security Department’s Cybersecurity and Infrastructure Security Agency (CISA) within 72 hours of a breach and 24 hours if the organization made a ransomware payment. It also grants CISA the power to subpoena entities that don’t report a cyber incident or ransomware payment. 

The measure becoming law is a complete reversal from only a few months ago when it was stripped from the annual defense policy bill.

CISA will have up to two years to publish a notice in the Federal Register on proposed rulemaking to implement the reporting effort, though it may move faster due to heightened concerns about Russian cyberattacks bleeding out of Moscow’s invasion of Ukraine.

“This historic, new law will make major updates to our cybersecurity policy to ensure that, for the first time ever, every single critical infrastructure owner and operator in America is reporting cyber-attacks and ransomware payments to the federal government,” Senate Homeland Security Committee Chair Gary Peters (D-Mich.), who authored and championed the legislation along with Sen. Rob Portman (R-Ohio), said in a statement.

Portman, the panel’s top Republican said the legislation will “give the National Cyber Director, CISA, and other appropriate agencies broad visibility into the cyberattacks taking place across our nation on a daily basis to enable a whole-of-government response, mitigation, and warning to critical infrastructure and others of ongoing and imminent attacks.”

Take a dev-centric approach to cloud-native AppSec testing

Category: App Security,Information SecurityDISC @ 10:09 am

While some applications are still being built on a monolithic (all-in-one) architecture – i.e., all components in a single code base, on a single server, connected to the internet – an increasing number of them is now based on the microservices architecture, with each application microservice a self-contained functionality, “housed” in a container managed by an orchestrator like Kubernetes, deployed on the cloud (public or private), and communicating with other application microservices over the network in runtime.

But with applications no longer self-contained, security vulnerabilities are no longer present just in the code; vulnerabilities can “start” on one microservice, go through multiple components, and “finish” on a different microservice.

“We are no longer dealing with just vulnerabilities, but also with vulnerable flows between microservices. On top of that, as cloud-native applications are built on multiple infrastructure layers – the container, the cluster, and the cloud – they way these layers are configured affects what a hacker can do with these vulnerabilities,” notes Ron Vider, one of the co-founders and the CTO of Oxeye.

Modern architectures require modern AppSec testing solutions

This dramatic change in how applications are structured has made traditional approaches to application security ineffectual and has created security blind spots for AppSec and DevOps teams.

“Old-school” software composition analysis (SCA) and static, dynamic, and interactive application security testing (SAST, DAST, IAST) tools are run independently, are not synchronized with one another, and are unable to cross-reference and use enriched data from other code layers in the environment. The incomplete and inaccurate results they provide when testing cloud-native apps have made it obvious that a new approach and new, better tools are needed.

cloud-native AppSec testing

Oxeye is one such tool. It essentially combines all AST methodologies with a new generation of security control assessment capabilities and, as a result, excels in finding and correctly prioritizing vulnerabilities in cloud-native applications that need to be addressed. It helps clear the noise of false positives/negatives delivered by legacy solutions, and allows developers and AppSec teams to focus on high-risk, critical vulnerabilities.

Getting started with Oxeye is fantastically easy: you need to deploy a single component (Oxeye Observer) into your staging or testing environment, and you do it by using a single YAML file containing its definitions.

cloud-native AppSec testing

“The Oxeye Observer immediately starts running within the cluster and starts it automatic discovery process,” Vider told Help Net Security.

“First it analyzes the infrastructure to understand how the application is configured, and it does that by communicating with the with the Docker API, the containerd API, the Kubernetes API and the cloud provider API, and fetching the relevant configuration. Then, it detects potential vulnerabilities in the code (the application’s code and the third-party components). Next, it analyzes the communication between the different components and traces their flow. Finally, it validates the found vulnerabilities by sending payloads to the application and analyzing its behavior, to understand whether it’s exploitable or not.”

Ukraine: Belarusian APT group UNC1151 targets military personnel with spear phishing

Category: Information Security,Malware,PhishingDISC @ 10:02 am

The CERT of Ukraine (CERT-UA) warned of a spear-phishing campaign targeting Ukrainian armed forces personnel.

The Computer Emergency Response Team of Ukraine (CERT-UA) is warning of an ongoing spear-phishing campaign targeting private email accounts belonging to Ukrainian armed forces personnel.

The Ukrainian agency attributes the campaign to the Belarus-linked cyberespionage group tracked as UNC1151.

In mid-January, the government of Kyiv attributed the defacement of tens of Ukrainian government websites to Belarusian APT group UNC1151. Defaced websites were displaying the following message in Russian, Ukrainian and Polish languages.

“Ukrainian! All your personal data has been sent to a public network. All data on your computer is destroyed and cannot be recovered. All information about you stab (public, fairy tale and wait for the worst. It is for you for your past, the future and the future. For Volhynia, OUN UPA, Galicia, Poland and historical areas.” reads a translation of the message.

In November 2021, Mandiant Threat Intelligence researchers linked the Ghostwriter disinformation campaign (aka UNC1151) to the government of Belarus. In August 2020, security experts from FireEye uncovered a disinformation campaign aimed at discrediting NATO by spreading fake news content on compromised news websites. According to FireEye, the campaign tracked as GhostWriter, has been ongoing since at least March 2017 and is aligned with Russian security interests.

Unlike other disinformation campaigns, GhostWriter doesn’t spread through social networks, instead, threat actors behind this campaign abused compromised content management systems (CMS) of news websites or spoofed email accounts to disseminate fake news.

Now Serhiy Demedyuk, deputy secretary of the national security and defence council, told Reuters, that the Ukrainian government blamed the UNC1151 APT group. Demedyuk explained that the attacks were carried out to cover for more destructive actions behind the scenes. 

The nation-state group is using the compromised accounts to target contacts in the victims’ address books. Attackers spear-phishing messages have been sent from email accounts using the domains 

 and .

The phishing messages used a classic social engineering technique in the attempt to trick victims into providing their information to avoid the permanent suspension of their email accounts.

The phishing attacks are also targeting Ukrainian citizens, reported the State Service of Special Communications and Information Protection of Ukraine (SSSCIP).

50 Key Stats About Freedom of the Internet Around the World

Almost every part of our everyday lives is closely connected to the internet – we depend on it for communication, entertainment, information, running our households, even running our cars.

Not everyone in the world has access to the same features and content on the internet, though, with some governments imposing restrictions on what you can do online. This severely limits internet freedom and, with it, the quality of life and other rights of the affected users.

Internet freedom is a broad term that covers digital rights, freedom of information, the right to internet access, freedom from internet censorship, and net neutrality.

To cover this vast subject, we’ve compiled 50 statistics that will give you a pretty clear picture about the state of internet freedom around the world. Dig into the whole thing or simply jump into your chosen area of interest below:

Master decryption keys for Maze, Egregor, and Sekhmet ransomware leaked online

Category: Information Security,RansomwareDISC @ 10:19 am

The master decryption keys for the Maze, Egregor, and Sekhmet ransomware families were released on the BleepingComputer forums by the alleged malware developer.

The Maze group was considered one of the most prominent ransomware operations since it began operating in May 2019. The gang was the first to introduce a double-extortion model in the cybercrime landscape at the end of 2019. At the end of 2019, the Maze ransomware implemented data harvesting capabilities and started threatening the victims to release the stolen data for all those victims who refuse to pay the ransom.

In November 2020, the Maze ransomware operators announced that they have officially shut down their operations and denied the creation of a cartel.

Maze operation then rebranded in September as Egregor, but on February 2021 several members of the Egregor group were arrested in Ukraine.

The Sekhmet operation was launched in March 2020 and it has some similarities with the above ransomware operations.

While TTP’s of Egregor operators are almost identical to that of ProLock, the analysis of Egregor ransomware sample obtained during an incident response conducted by Group-IB revealed that the executable code of Egregor is very similar to Sekhmet. The two strains share some core features, use similar obfuscation technique. Egregor source code bears similarities with Maze ransomware as well.

Now the decryption keys for these operations have now been leaked in the BleepingComputer forums. The keys were shared by a user named ‘Topleak’ who claims to be the developer for all three operations.

“Hello, It’s developer. It was decided to release keys to the public for Egregor, Maze, Sekhmet ransomware families. also there is a little bit harmless source code of polymorphic x86/x64 modular EPO file infector m0yv detected in the wild as Win64/Expiro virus, but it is not expiro actually, but AV engines detect it like this, so no single thing in common with gazavat.” the user wrote on the forum.

“Each archive with keys have corresponding keys inside the numeric folders which equal to advert id in the config. In the “OLD” folder of maze leak is keys for it’s old version with e-mail based. Consider to make decryptor first for this one, because there were too many regular PC users for this version. Enjoy!”

TopLeak user pointed out that it is a planned leak, and is not linked to recent arrests and takedowns conducted by law enforcement. The alleged ransomware developer added that none of the ransomware gang will ever return in ransomware operation and that the source code of tools ever made is wiped out.

In one of the archives leaked by the user there is the source code for a malware dubbed ‘M0yv’ that was part of the gang’s arsenal.

3 key elements of a strong cybersecurity program

The world relies on technology. So, a strong cybersecurity program is more important than ever. The challenge of achieving good cyber hygiene can be especially acute for small- and medium-sized businesses. This is particularly true for those with fully remote or hybrid work environments. Add to the mix limited resources and limited talent focused on cybersecurity, and the challenges can seem overwhelming.

Considering this, we’ve simplified things down to three key elements of a strong cybersecurity program. You need to know how to assess, remediate, and implement security best practices at scale. In more detail, this means:

  • Assessing your organization’s current cybersecurity program and its prioritization
  • Remediating endpoints at scale, bringing them into compliance with security best practices
  • Implementing cybersecurity policies and monitoring them to stay in compliance

1. Assess your organization’s current cybersecurity program

Taking the first step toward better cyber hygiene means understanding where your organization stands today. Conduct an honest assessment of your strengths and weaknesses in order to prioritize where to focus your efforts for your cybersecurity program. The challenge here is finding the right bar to measure yourself against. There are several frameworks that will do the job. Thus, it can be daunting to figure out which one is the right fit, especially if this is the first time you’re doing an assessment. Starting with the CIS Controls and CIS Benchmarks can help take the guesswork out of your assessment and provide peace of mind that you’re covering all of your bases.

Here’s what makes these two sets of best practices especially useful:

  • They tell you the “what” and the “how”: Many frameworks tell you what you should do, but not how to do it. CIS best practices give you both.
  • They are comprehensive and consensus-based: CIS best practices are developed in collaboration with a global community of cybersecurity experts. They’re also data-driven as explained in the CIS Community Defense Model.
  • They are mapped to other industry regulatory frameworks: CIS best practices have been mapped or referenced by several other industry regulatory requirements, including: NIST, FINRA, PCI DSS, FedRAMP, DISA STIGs, and many others. This means you can get the proverbial “two birds with one stone” by assessing against CIS best practices.

The CIS Controls are a prioritized and prescriptive set of safeguards that mitigate the most common cyber-attacks against systems and networks. The CIS Benchmarks are more than 100 configuration guidelines across 25+ vendor product families to safeguard systems against today’s evolving cyber threats. Both are available as free PDF downloads to help you get started.

2. Remediate endpoints at scale with CIS Build Kits

One of the challenges in applying any best practice framework is dedicating the time and resources to do the work. Luckily, CIS offers tools and resources to help automate and track the assessment process. The CIS Controls Self Assessment Tool (CIS CSAT) helps organizations assess the implementation of the CIS Controls. Additionally, the CIS Configuration Assessment Tool (CIS-CAT Pro Assessor) scans target systems for conformance to the CIS Benchmarks. CIS-CAT Pro Assessor allows you to move more quickly toward analyzing results and setting a strategy to remediate your gaps.

CIS resources and tools are designed to help you move toward compliance with best practices by remediating the gaps. Once you understand where your gaps are and how to fix them, you can use CIS Build Kits to achieve compliance at scale. CIS Build Kits are automated, efficient, repeatable, and scalable resources for rapid implementation of CIS Benchmark recommendations. You can apply them via the group policy management console in Windows, or through a shell script in Linux (Unix,*nix) environments.

Interested in trying out a Build Kit? CIS offers sample Build Kits that contain a subset of the recommendations within the CIS Benchmark. They provide you a snapshot of what to expect with the full CIS Build Kit.

3. Implement cybersecurity policies and monitor for compliance

Lastly, creating strong policies and monitoring conformance helps ensure that an organization is working toward a more robust cybersecurity program. Regularly monitoring conformance over time is critical. It helps you avoid configuration drift, and helps identify any new issues quickly. CIS tools can help monitor conformance and identify gaps.

CIS-CAT Pro Dashboard provides an easy-to-use graphical user interface for viewing CIS Benchmark conformance assessment results over time. Similarly, CIS CSAT Pro enables an organization to monitor implementation of the CIS Controls over time.

What Is Information Risk Management? Definition & Explanation

Category: Information Security,Security Risk AssessmentDISC @ 12:54 am

Information risk management is the process of identifying the ways an organisation can be affected by a disruptive incident and how it can limit the damage.

It encompasses any scenario in which the confidentiality, integrity and availability of data is compromised.

As such, it’s not just cyber attacks that you should be worried about. Information risk management also includes threats within your organisation – such as negligent or malicious employees – as well as residual risks.

For example, the framework can help you address misconfigured databases, software vulnerabilities and poor security practices at third parties.

In this blog, we take a closer look at the way information risk management works and how organisations can use its guidance to bolster their security defences.

Why is information risk management important?

In the face of ever-growing cyber threats, it can be difficult for an organisation to protect its information assets.

Last year, the World Economic Forum listed cyber crime alongside COVID-19, climate change and the debt crisis as the biggest threats facing society in the next decade. It’s clear, then, that organisations need a plan for identifying and addressing security risks.

With an information risk management system, organisations gain a better understanding of where their information assets are, how to protect them and how to respond when a breach occurs.

One way it does this is by forcing organisations to not only identify but also assess their risks. This ensures that organisations prioritise scenarios that are most likely to occur or that will cause the most damage, enabling them to make informed decisions in line with their security budget.

How risk management works

To understand how risk management programmes work, we need to take a closer look at what ‘risk’ actually is.

In an information security context, risk can be defined as the combination of a vulnerability and a threat.

As we’ve previous discussed, a vulnerability is a known flaw that can be exploited to compromise sensitive information.

These are often related to software flaws and the ways that criminal hackers can exploit them to perform tasks that they weren’t intended for.

They can also include physical vulnerabilities, such as inherent human weaknesses, such as our susceptibility to phishing scams or the likelihood that we’ll misplace a sensitive file.

This is different from a threat, which is defined as the actions that result in information being compromised.

So, to use the examples above, threats include a criminal hacker exploiting a software flaw or duping an employee with a bogus email.

When a threat meets a vulnerability, you get a risk. In the case of the criminal hacker phishing an employee, the risk is that the attacker will gain access to the employee’s work account and steal sensitive information. This can result in financial losses, loss of privacy, reputational damage and regulatory action.

A risk management system helps organisations identify the ways in which vulnerabilities, threats and risks intertwine. More importantly, it gives organisations the ability to determine which risks must be prioritised and identify which controls are best equipped to mitigate the risk.

Start protecting your business

At the heart of risk management is the risk assessment. This is the process where threats and vulnerabilities are identified. Organisations can use the result of the assessment to plan their next moves.

This process can be labour-intensive, but you can simplify the task with our risk assessment tool vsRisk.

With vsRisk, you’ll receive simple tools that are specifically designed to tackle each part of the risk assessment.

This software package is:

  • Easy to use. The process is as simple as selecting some options and clicking a few buttons.
  • Able to generate audit reports. Documents such as the Statement of Applicability and risk treatment plan can be exported, edited and shared across the business and with auditors.
  • Geared for repeatability. The assessment process is delivered consistently year after year (or whenever circumstances change).
  • Streamlined and accurate. Drastically reduces the chance of human error.

Cybersecurity staff turnover and burnout: How worried should organizations be?

Category: Information SecurityDISC @ 10:13 am

The heightened risk of cyberattacks on businesses is being compounded by significant recruitment and retention issues within cybersecurity teams, making businesses more vulnerable to potential attacks, according to a research from ThreatConnect.

cybersecurity teams retention issues

With the number of data breaches in 2021 soaring past that of 2020, there is added pressure on cybersecurity teams to keep businesses secure. The research has found a concerning level of staff turnover, skills shortages, burnout, and low staff morale, pointing towards depleted reserves trying to manage the growing risk.

Cybersecurity teams recruitment and retention issues

  • Senior decision-makers across the US report an average security staff turnover rate of 20%.
  • 64% of senior decision-makers have seen a rise in turnover over the past year.
  • 43% of US respondents attribute a lack of skills as the biggest barrier for recruitment.
  • 1 in 5 US respondents are considering quitting their jobs in the next six months.
  • 57% of US respondents have experienced an increase in stress over the past six months.

The COVID-19 pandemic has created what many are calling the Great Resignation, which has affected all industries for the past two years. Employees, specifically those in the security industry, are now being expected to do more with less.

Cybercrime has increased significantly over the past year, making digital protection for businesses both more important and more difficult to achieve. Companies cannot afford to lose any security team members with cybercrime increasing so rapidly.

“In today’s digital ecosystem it is crucial that security employees receive adequate training, support, and resources needed to work efficiently in their jobs,” said Adam Vincent, CEO of ThreatConnect. “As employee turnover increases in this sector, it creates a vicious cycle that impacts a company’s performance and ability to mitigate cyber risks.”

“This makes it even more difficult for security teams to fulfill the company’s needs. Organizations must look at these numbers and recognize that there is more that can be done to protect their employees and in turn, the welfare of their company.”
