Global economic insecurity and rise of insider threats

Category: Insider Threat — DISC @ 6:04 pm

information

According to BBC news article by Maggie Shiels (Feb 11, 2009) the world’s biggest software maker has warned companies to expect an increase in “insider” security attacks by disgruntled, laid-off workers. Microsoft said so-called “malicious insider” breaches were on the rise and would worsen in the present downturn.





Below are the high points:
• With 1.5 million predicted job losses in the US alone, there’s an increased risk and exposure to these attacks

• Insider threat is one of the most significant threats companies face. Said Microsoft Doug Leland

• The malicious insider is classed as the greatest security concern because they have access, and relatively easy access to corporate assets

• During economic insecurity people are motivated by revenge, fear or greed

• 88% of data breaches were caused by simple negligence on the part of staff

• Employees steal information to sell to a third party, to get back at a company for being laid off or demoted or to try and get a job at another company

• Even though Insiders attacks are lower in numbers but they could be more devastating because the employee knew where “the crown jewels” were kept – unlike a hacker who had to go on something of a “fishing expedition” to find a company’s valuable assets

• The outstanding, unsolved, unaddressed risk management problem that has existed for years is that everyone is focusing on the hacker

• Data loss prevention systems specialize in the detection of precisely these events

Here is the article: Malicious insider attacks to rise

To find the correct balance between data security and data availability, organizations are urged to buy a copy Data Breaches: Trends, costs and best practices.

Even in good time management focused on driving shareholder value by increasing revenue and profits. I think during this economic downturn information security will be the last thing on their mind which will not only compound the problem but gives an edge to a attacker and simply a bad business decisions considering the circumstances. It’s about time to start paying attention to regulatory compliance for sake of securing organization assets. Good place to start is to have some sort of baseline based on information security framework and come up with a strategy to improve that baseline. ISO assessment can be utilized to baseline the organization security posture and is a great first step towards ISO 27002 compliance or for that matter any compliance audit.

What do you think board rooms are appropriately prepared to tackle or perhaps slow down the wave of data breaches coming our way?

ISO 27k and CMMI

Category: Information Security,ISO 27k — DISC @ 2:00 am

To become a successful business in today’s market, optimized information security controls may be the panacea for unmet security needs. One way to achieve optimized information security control is to perform ISO assessment and assess the organization security posture based on ISO 27002 code of practice and map each control with Capability Maturity Model Integration (CMMI) to find out the current CMMI level for each control. information The goal is to address the organization security needs as a whole, and assess how different departments and business functions are addressing the current business security requirements. The CMMI has five levels and evaluate security controls based on levels, not on specific objectives. Each level provides the basis for the next level where it is not possible to get to the next level without complying with previous level. ISO 27002 is a comprehensive framework which can be utilized to obtain the baseline upon which to build each level. For each control in ISO 27002, maturity levels are defined using maturity definition found in CMMI. In the assessment report maturity level of each control of ISO 27002 standard can be evaluated. Utilizing the color coded scheme provided by CMMI model, create a one page ISO control summary for executives which will not only help them to understand the current security posture but also can be instrumental for measuring progress and resource allocation.

The scope of the ISO27k standards includes various aspects of IT. The introduction to ISO 27002 states clearly: “Information can exist in many forms. It can be printed or written on paper, stored electronically, transmitted by post of using electronic means, shown on films, or spoken in conversation. Whatever form information takes, or means by which it is shared or stored, it should always be appropriately protected.”

Benefits of ISO 27k framework:
o Framework addresses the security issues for the whole organization and limit data breaches
o Address compliance with various regulations like (SOX, HIPAA, and PCI) without creating silos.
o Reduce total cost of security by decreasing total number of controls required
o Perception of your business that you are serious about information security not just compliance
o Enhance partners and vendors confidence to do business with your organization
o Future deciding factor for national and especially international partners for more business
o Internationally recognized standard which addresses security awareness for the whole organization

Assessment will give an organization a high level view of their current security posture and provide a road map for security strategy in a sense what needs to be addressed first utilizing risk based approach. This is also a good start if your organization is interested in the Information Security Management System (ISMS) or ISO 27001 certification. ISO 27001 is the standard for the certification which includes the set of requirements for ISMS. Justifiable scoping is the key to a quick and successful certification; organization may adjust their scope in a re-certification attempt. Perhaps in the first attempt you may need to include just a web portal in your scope and the entire infrastructure behind supporting that portal. Once the ISMS project scope is determined, here are some steps you can follow to prepare for ISO 27001 auditors.

1. Based on your scope, create an asset list
2. Find out asset threats and vulnerabilities and classify the asset based on CIA scale
3. Come up with risk matrix based on impact and likelihood of the risk
4. Create priorities based on impact and likelihood of the risk
5. Based on priorities, implement appropriate controls for risks which needs to be addressed
6. Do the risk assessment again, PDCA improve ISMS

“ISO27001 is a structured, technology-neutral, vendor-agnostic specification and code of practice for information security management in organizations of all sizes that should be adopted as part of an organization’s overall risk management strategy.”

This should give you a jump start to certification. You have already started the process of certification because most of the documentations in the risk assessment will become part of certification process later and will lead you to 12 steps which are part of PDCA cycle. ISMS certification process utilized Plan-Do-Check-Act (PDCA) cycle methodology which continually improve information security management system and meet the contractual, legal, and regulatory requirements for information security.

ISO assessment is utilized to analyze the current security posture of an organization where each control is defined and can be color coded using the base definition found in CMMI. Therefore ISO assessment is a great first step towards the final ISO 27001 certification audit or for that matter any compliance audit.

Cyber threats and overall security assessment

In the past when senior management (execs) needed to understand the financial implication of cyber threats and their exposures, they turned their questionnaires toward IT for relevant answers. In other words IT risk assessment was the answer in the past to understand the financial implications of cyber threats. The IT risk assessment is not the comprehensive or overall assessment of the company to understand the total implications of cyber threats. The overall assessment will not only include IT but also other departments like HR and legal etc… Basically cyber threats are neither IT issue and nor a legal or HR issue any more, it’s simply an enterprise management issue.

In old days the firewall was used as a major defense against potential cyber threats. The new cyber threats are sophisticated enough to demand better defense. New threats (virus, adware, worms, Trojan, spyware, spam, phishing) use modern techniques to bypass defenses. The potential risks of these new threats demand an immediate attention (of CFO or higher) and approval for resource allocation to protect against cyber threats. To make a solid business case for security ROI, senior level execs need to know the overall risk they are reducing, and their highest priority.

[TABLE=12]

ANSI and ISA have jointly released a document to assist senior management to prepare for financial implications for cyber threats. Basic essence of the guide is to provide a tool to execs to understand the financial implications of potential cyber threats to their organizations.

“The 40 page guide was put together by task force of risk management execs from more than two dozen organizations. The new guide offered by ANSI and the ISA recommends that CFO ask their various team’s questions about the biggest threats to data confidentiality, integrity and availability,” to get to know the existing controls in place and any relevant mitigation plan. Risk analysis of this information can help execs to map the cyber threats risks into correct financial terms and make better resource allocation.
The senior execs who want to implement information security as a process in their organization should consider ISO 27001 (ISMS) as a best practice, which provides a reasonable on-going due diligence to protect and safeguard organization data.
