Cyber Threats and Nuclear Weapons

“The technology controlling United States nuclear weapons predates the Internet. Updating the technology for the digital era is necessary, but it comes with the risk that anything digital can be hacked. Moreover, using new systems for both nuclear and non-nuclear operations will lead to levels of nuclear risk hardly imagined before. This book is the first to confront these risks comprehensively. With Cyber Threats and Nuclear Weapons, Herbert S. Lin provides a clear-eyed breakdown of the cyber risks to the U.S. nuclear enterprise. Featuring a series of scenarios that clarify the intersection of cyber and nuclear risk, this book guides readers through a little-understood element of the risk profile that government decision-makers should be anticipating. What might have happened if the Cuban Missile Crisis took place in the age of Twitter, with unvetted information swirling around? What if an adversary announced that malware had compromised nuclear systems, clouding the confidence of nuclear decision-makers? Cyber Threats and Nuclear Weapons, the first book to consider cyber risks across the entire nuclear enterprise, concludes with crucial advice on how government can manage the tensions between new nuclear capabilities and increasing cyber risk. This is an invaluable handbook for those ready to confront the unique challenges of cyber nuclear risk”–

Five ways to lose your identity

Category: Identity Theft — DISC @ 2:42 pm

By Jaikumar Vijayan
The rush by shoppers to the Web makes the season a great time for online retailers. It’s also a great time for hackers looking to steal data and money from the unwary millions expected to search for great deals online.

Checkout huge savings on Today’s Hot Deals on Information Security Solutions for the holidays

The growth of holiday hackers has annually prompted security analysts, identity theft awareness groups, and various government agencies to come up with lists of precautions that consumers can take to avoid becoming a victim of online fraud. Such lists can prove a benefit to consumers, but unfortunately some people ignore it.

Below are the identity theft awareness tips which can help maximize your exposure to online fraud.

Tip No. 1: Open all attachments from strangers and click on all embedded links in such e-mail messages. Such actions remain one of the most effective ways to provide thieves with personal information and financial data. All a hacker needs to do is find computer users who instinctively open e-mail messages from strangers, even those who write in a foreign language. The action can open the door to keystroke loggers, rootkits, or Trojan horse programs. Crooks can also easily install backdoors to easily steal data without attracting any attention. Once installed, hackers gain unfettered access to personal data and can even remotely control and administer systems from anywhere.

Tip No. 2: Respond to Dr. (Mrs.) Mariam Abacha, whose name is used by many hackers who say they have close friends and relatives in Nigeria who have recently been widowed or deposed in a military coup and need your help to get their millions of dollars out of the country. Users are told they will undoubtedly be rewarded for helping to get their “well-packed trunk boxes” full of cash out of Nigeria. And to make sure to provide bank account information, login credentials, date of birth, and mother’s maiden name so that they can wire the reward directly into a checking account in time for the holidays.

Tip No. 3: Install a peer-to-peer file-sharing client on your PC and configure it so all files, including bank account, Social Security, and credit card numbers, along with copies of mortgage and tax return documents, are easily available to anyone on the same P2P network. Your personal data will stream over the Internet while you check out what songs you can download for free without getting sued by the RIAA.

Tip No. 4: Come up with passwords that are easy to crack. It saves hackers from spending too much time and effort trying to access your PC. Clever sequences such as “123456” and “abcdef” and your firstname.lastname all make fine, easy-to-remember default passwords for you and for hackers. For maximum exposure, keep passwords short, don’t mix alphabets and numerals, and use the same password for all accounts.

Tip No. 5: Avoid installing the latest anti-malware tools and security updates. Keeping operating systems properly patched and anti-virus and anti-spyware tools updated make life hard for hackers. Users can help them out by making sure their anti-virus software and anti-spyware tools are at least 18 months out of date or by not using them at all. Either way, it’s very likely that your computer will be infected with a full spectrum of malware.

Web 2.0 and malware 2.0

Category: Malware,Web 2.0 — DISC @ 5:43 pm

Web 2.0 - No one owns it
A new position paper from ENISA describes the risks associated with web 2.0 and malware 2.0. Web 2.0 includes social networking, photo sharing, wikis and social bookmarking sites and malware 2.0 is defined as a web based infection in which user can be entrap by visiting website.

Web 2.0 applications are thriving because of their dynamic contents, in which users chip into the content and interact with each other. This dynamic interaction with other users comes with new threats of malware 2.0, in web 2.0 environment user trust the information without knowing anything about the author or integrity of the source, and that’s precisely why criminals are attacking these applications and using it to circulate malware 2.0.

ENSIA survey also evaluates the methods used by people to figure out if the web page is phony. People will be suspicious of a source if it only appears once on the web, but will start trusting the source (integrity of the source) if it appears more than once on the web. Assumption is somebody down the chain might have validated the source and as the source start spreading on the web somehow people start believing in the authenticity of the content.

“Misinformation is easily propagated through syndicated news stories, blog posts, and social data, which provides few trust cues to users. This has very serious consequences such as stock price manipulation and control of botnet via RSS feeds”

There is a need to establish an independent third party on the web to validate the source of the content. Availability of the web 2.0 content has to be balanced with a fitting dose of confidentiality and integrity of the content.

Laptop and traveling precautions

Category: Laptop Security — DISC @ 12:58 am

Laptop security

Best practice emphasize the fact to backup the data if you can’t live without it, in the same way a traveler must avoid taking sensitive data on the road unless it’s absolutely necessary to do so. If you do plan to take sensitive data with you on the laptop, the necessary security controls must be implemented and go with the sensitive data. The data protection controls should be based on your information security policy data classification.

The laptop hardware itself is only worth few hundred dollars these days, but on the other hand it’s hard to put a price tag on the exposed data which may have a drastic impact on your organization, especially these days when most of the organizations are at the edge due to financial chaos.
Frequent travelers know it’s possible to lose a laptop or lose data because laptop may become inoperable due to hardware malfunction. Planning an important business trip should include encrypting sensitive data and backup on a remote website (Carbonite). So in case you lose your laptop or it’s is inoperable for some reason, you can remotely recover backed up files from site within reasonable time.

[TABLE=8]

Here is how you can encrypt your data on Windows laptop with built-in utility EFS

1. Create a new folder, and name the folder Private.
2. Right click the new folder and choose properties
3. Click advanced button
4. Check encrypt contents to secure data box and then click OK, Apply and OK again.

You have created a secure area where you can put your sensitive documents. Any file or subfolder you add to this folder (Private) will be encrypted automatically. Basically any type of file except Windows system file will be encrypted in this folder. Now if the attacker steal your laptop and remove your hard drive and mount on a system where the attacker has administrative privileges, the attacker will not be able to access the contents of the folder Private. On the other hand 256-bit AES encryption key is stored in encrypted form as a file attribute called the data decryption field (DDF). The EFS private key, needed to decrypt the DDF and extract the file encryption key, is also stored in encrypted form in the registry. The master key, which is used to obtain the key needed to access the EFS private key, is encrypted by the systems key and also stored locally. So the attacker will be able to decrypt the EFS protected files if he can somehow get possession of the system key.

Luckily we do have a choice whether to store the system key locally on your laptop. If you click start, then Run and then launch syskey.exe utility, you can choose how and where the system key will be stored. The dialogue box will present three options.

1. Store the startup key locally
2. Store the startup key on the floppy disk
3. Generate the startup key from a password

With the two non default options, you will be requiring to either insert the floppy or enter the password whenever the laptop is BOOTED. The floppy option is highly inconvenient for laptop users but the password options seem sufficient to protect the laptop data. On the laptop which doesn’t have a floppy drive, don’t try to click the floppy option because when you boot next time the laptop will be looking for the system key on a floppy before booting.

12 Phishing Threats and Identity Theft

Category: Email Security,Identity Theft — DISC @ 7:22 pm

Have you ever thought of losing something and you cannot live without it? Yes, that something can be your identity. Phishing is a practice of luring unsuspecting Internet users to a fake Web site by using authentic-looking email with the real organization’s logo, in an attempt to steal passwords, financial or personal information. In daily life people advise to retrace your steps when you lose something. The question is how you retrace your steps on cyberspace where some uber hackers know how to erase their footsteps to avoid detection. It is difficult to find phishers in cyberspace, and jurisdictional issues make it even harder to prosecute them. Then there is an issue of trust that phishers dupe people to believe that their web site is not fraudulent to collect personal/financial information.

Amongst the financial crisis, phishing might be on the rise because for many organizations information protection might be the last thing on their mind. The FDIC has created a webpage to inform and warn consumers about “phishing.” These days phishers have targeted social network organizations LinkedIn and Facebook where their members have been duped into revealing their sensitive data.

Mainly phishing attacks are targeted to steal the identity. Now the question is, how easy it is to steal somebody’s identity? Let’s say a phisher has your name and address, and then he/she can get your Social Security number with the search on AccurInt or other personal database website. A Social Security number is not the only bounty a fraudster can find on these websites, other personal/private information is available as well at minimal cost.

In the table below are the 12 threats to your online identity which can be manipulated in phishing scams, and possible countermeasures to protect your personal and financial information. Some threats are inadequate or no security controls in place. The last row of the table is a monitoring control to identify the warning signs of identity theft.

[Table=7]

Organizations should take necessary steps to protect against identity fraud and apply whatever state and federal legislation applies to your business. Organizations which are serious about their information security should consider implementing the ISO 27001 (ISMS) standard as a best practice, which provides reasonable due diligence to protect and safeguard your information.

SmartPhone and Security

Category: Information Security,Smart Phone — DISC @ 1:53 am

Mobile spyware is malicious software which is used to spy and control mobile devices (BlackBerry, PDAs, Windows Mobile and Cell Phones). Mobile spyware will not only intercept the message between two devices but also determine the location of the device. Basically, mobile spyware software is installed on a mobile device to spy on them.

Small businesses are usually not equipped to handle these threats. Just like laptops and desktops – mobile devices need security controls like antivirus, personal firewall, encryption and VPN to provide needed level of protection. Small businesses need to be aware of the security threats, like they might think that they are installing a game, which might very well be a key logger (logs your key strokes) or trojan software.

Risk Assessment and System Profiling

Category: Risk Assessment — DISC @ 2:39 am

In real estate it’s all about location and the same way to succeed in information security risk assessment, it’s all about precise profiling of a system under review. The system profile sets the boundaries of an assessment and the reviewer includes or excludes assets in the review based on their criticality and sensitivity and the business objective of an assessment. A poorly defined system profile will result in a poor quality risk assessment effort, and puts the system at unnecessary risk. A well defined system profile covers all the unacceptable risks to the system and hence is the precursor to a successful risk assessment.


In order to understand business and operational risks, before setting up the scope of an assessment the system under review needs to be profiled with the business owner or system custodian.  For an effective system profile, it is necessary to understand the objective of an assessment, needs driving the project and any inherent threats and weaknesses to the system. In a system profile the reviewer finds out all the main business functions performed by the system and its contribution to the key business objectives is determined. These business objectives will drive the data classification and system criticality of the system profile.  The business impact rating is determined based on financial, operational, technological and physical threats to the confidentiality, integrity and availability of the system


System Interdependencies and Interfaces:


System boundaries identify where one system begins and other one ends. Determining all the interfaces to other systems is an important part of profiling the system. An interface is a connection between two systems, so most systems have multiple interfaces. The reviewer needs to determine what kind of communication and authentication protocols are utilized in the interfaces and how often the passwords are changed on these interfaces. To cover all the related interdependencies of a system, all the relevant application, operating systems, hardware, communication protocol, network topology, dataflow architecture needs to be profiled.  All the applications and operating systems (current release, life cycle, patch cycle) authentication and authorization details need to be evaluated as well. (Who needs authorized access, how often, and are there any exceptions?)


The best way to gather relevant information for an accurate profile is to conduct on-site interviews with the business owner and relevant subject matter experts. In addition, questionnaires, document review and scanning tools can be utilized as well.  Based on the system criticality and data classification and all the other relevant threats to the system, the overall business risk to the system is determined which is based on a (high, medium and low) scale. A carefully done system profile is integral to a sound risk assessment and ensures a common understanding of the system under review. Several business functions can utilize this valuable data and valid security decisions can be made.
