5 Must Read Books to Jumpstart Your Career in Risk Management

Category: Risk Assessment,Security Risk AssessmentDISC @ 11:30 am

FAIR Institute blog by Isaiah McGowan

Read Books to Jumpstart Your Career in Risk Management

What are the must have resources for people new to operational and cyber risk? This list outlines what books I would recommend to new analyst or manager.

They’re not ranked by which book is best. Instead, I list them in the recommended reading order. Let’s take a look at the list.

hubbard_failure_of_risk_management_cover.jpg#1 – The Failure of Risk Management: Why It’s Broken and How to Fix It (Douglas Hubbard)

In The Failure of Risk Management, Hubbard highlights flaws in the common approaches to risk management. His solutions are as simple as they are elegant. (Spoiler alert: the answer is quantitative risk analysis). The Failure of Risk Management shows up as #1 because it sets the tone for the others in the list. First, understand the problems. With the common problems in mind you can identify them on a regular basis. The next book provides approaches to modeling the problem.

fair-book-cover.jpg#2 – Measuring and Managing Information Risk: A FAIR Approach (Jack Jones & Jack Freund)
In Measuring and Managing Information Risk, the authors communicate a high volume of foundational knowledge. The authors outline the FAIR-based approach to measuring and managing risk. They tackle critical concepts often overlooked or taken for granted by risk practitioners.

With that foundation in place, they move on to the FAIR approach to risk analysis. Finally, they lay out foundational concepts for risk management.

This book is not an advanced perspective on analyzing or managing risk. Instead, it provides a systemic solution to our problems.

Books #1 and #2 lay the foundation to understand the common risk management and analysis problems. They also provide approaches for solving those problems. The next two books are critical to improving the execution of these approaches.

Superforecasting_cover.jpg#3 – Superforecasting: The Art and Science of Prediction (Phillip Tetlock & Dan Gardner)

We require Superforecasting. Risk analysis is always about forecasting future loss (frequency and magnitude). As practitioners, it is critical to learn the problems with forecasting. Knowing is half the battle. Superforecasting takes the audience through the battlefield by offering a process for improvement.

If there is one book you could read out of order, it is Superforecasting. Yet, it shows up at #3 because it will hammer home forecasting as a skill once the other books open your eyes.

Tetlock_expert_judgement_cover.jpg#4 – Expert Political Judgment: How Good Is It? How Can We Know? (Phillip Tetlock)

Yes, another book by Tetlock appears in our list. Published first, tackled second. His work in understanding forecasting is tremendously valuable. Superforecasting builds on the research that resulted in publishing Expert Political Judgment.

Tetlock seeks to improve the reader’s ability to identify and understand errors of judgment. If we improve this skill, we will improve our ability to evaluate expert inputs in risk management.

Thinking_fast_and_slow_cover.jpg#5 – Thinking, Fast and Slow (Daniel Kahneman)

Rounding out the list is Thinking, Fast and Slow. Improving your understanding of thinking in general is the next best step. Take the time to read this book. Peel out nuggets of wisdom before tackling more advanced risk management and analysis concepts.

There it is…

This is my go-to list of 5. I recite it to anyone who has made or will make the leap into risk management and analysis. These books will set the foundation for thinking about risk. They will also push you down a path towards improving your skills beyond your peers.
What books would you have in your top 5? How does your mileage vary?

Case studies and chapter summaries impart expert guidance to provide the best grounding in information risk available for risk managers and non-specialists alike.

For any modern business to thrive, it must assess, control, and audit the risks it faces in a manner appropriate to its risk appetite. As information-based risks and threats continue to proliferate, it is essential that they are addressed as an integral component of your enterprise’s risk management strategy, not in isolation. They must be identified, documented, assessed, and managed, and assigned to risk owners so that they can be mitigated and audited.

Fundamentals of Information Risk Management Auditing provides insight and guidance on this practice for those considering a career in information risk management, and an introduction for non-specialists, such as those managing technical specialists.

 Book overview

Fundamentals of Information Risk Management Auditing – An Introduction for Managers and Auditors has four main parts:

  • What is risk and why is it important? An introduction to general risk management and information risk.
  • Introduction to general IS and management risks An overview of general information security controls, and controls over the operation and management of information security, plus risks and controls for the confidentiality, integrity, and availability of information.
  • Introduction to application controls An introduction to application controls, the controls built into systems to ensure that they process data accurately and completely.
  • Life as an information risk management specialist/auditor A guide for those considering, or undergoing, a career in information risk management.

Cyber Security and Risk Assessment

Category: cyber security,Security Risk AssessmentDISC @ 9:19 am

Cyber security is the protection of systems, networks and data in cyber space.

If your system is connected on the internet, you should know and uderstand the risks of cyber space to take appropriate countermeasures.

To understand the risks of cyber security,The first place is to begin with is a risk assessment. By completing a risk assessment you can understand what the risks, threats and vulnerabilities of your networks, systems and data really are and begin to comprehend how to reduce and handle them. The authors of The Information Security Risk Assessment Toolkit provides handy step-by-step guidance on how to undertake a risk assessment. As we said Security Risk Assessment is an important first to assess risks but the second step of mitigating those risks in timely manner is crucial to protect your information assets.

Once you understand what the risks of your business are, you can then decide on how to mitigate those risks based on your organization risk acceptance.

Tools and techniques which work in mitigating cyber risks

The UK’s Cyber-security Framework for Business (published by the Department for Business, Innovation and Skills) is a 10-step framework to stop around 80% of today’s cyber-attacks
1. Board-led Information Risk Management Regime
2. Secure Home and Mobile Working
3. User Education and Awareness
4. User privilege management
5. Removable media controls
6. Activity monitoring
7. Secure Configurations
8. Malware protection
9. Network security
10. Incident Management

Build the resilience in your information security management system (ISMS) to cope with the other 20% of the risk.

The authors of Hacking 7 Exposed cover the latest methods used by third-parties to (logical/physical) access to information assets. They then detail how you can protect your systems, networks and data from unauthorised access.

Cybersecurity standards are an important element in building a strong, resilient information and communications infrastructure. ISO/IEC 27001 is the most significant international best practice standard available to any organisation that wants an intelligently organised and structured framework for tackling its cyber risks

Impact of an Effective Risk Assessment to ISO 27001

Category: Security Risk AssessmentDISC @ 11:08 pm

RA

First to start with a definition of risk – Risk is a function of the probability that an identified threat will occur and then impact the mission or business objectives of an organization.

The kind of risks we deal with information assets are mostly those risks from which only loss can occur, which may be one of the reason why it’s hard for the security professionals to justify ROI for security controls. Comparatively business risks are attributed with either a profit or a loss. As we know, business folks make decision on risks on daily basis; it’s easier to make a decision for profit sake rather than on a loss. So increase risk to information asset will decrease the value of an asset or will harm the organization bottom line in some way.

To minimize the loss to an information asset, organization may decide to treat the higher risk assets which are above accepted risk threshold with following four ways:

1. Eliminate the risks
2. Reduce the risk to acceptable level
3. Accept the risk and live with it
4. Transfer by means of insurance

Risk Assessment Basic Steps for ISO 27001:

o Determine risk methodology and level of acceptable (residual) risk
o Identify assets and who owns them
o Identify the value of each asset
o Identify threats to each assets
o Identify vulnerabilities that each threat may exploit
o Estimate Likelihood of the threat exploiting vulnerability
o Finally determine risk the security of individual assets by combining impacts and likelihoods

Why SoD should be reviewed in every assessment

Category: Information Security,Security Risk AssessmentDISC @ 2:33 pm

Similar to other controls SoD (Segragation of Duties) plays an important role in reducing certain potential risk of an organization.

SoD minimize certail risks, by deviding a task so it will take more than one individual to complete a task or a critical process. SoD control has been traditionally used in accounting to minimize risk of collusion. For separation of duties we don’t want to give any individual so much control that they become a security risk without proper check and balance inplace. SoD is utilized to avoid unauthorized modification of data and to make sure critical data is available when needed by authorized personals, which includes but not limited to the availability of the services.

Separation of Duties (SoD) is not only an important principle of security but SoD control A10.1.3 of ISO 27001 wants organizations to implement this control.

Possible Controls to Implement SoD:

    * Separate the IT Dept from user function, meaning user should not be able to perform its own IT duties.
    * Separate the InfoSec and IT Dept. The individual responsible for the InfoSec has unique knowledge of organization security infrastructure, basically a knowledgeable InfoSec individual will have keys to the knigdom and should be segregated from the rest of the IT department. Also InfoSec individual should not be reporting to the IT director which is not only independence issue but conflict of interest. IT Dept is responsible for the avaiability of service whereas security professional is responsible for security (adding controls) to the same service.
    * The development and testing of application should be segregated. There should be a complete segregation of App development and App testing function. Also the person who put the App into production/operation and maintain should be a different individual.
    * Operation of IT should be seprate from maintenance of IT function in different teirs, meaning avaiability of the information should be separated from support & maintenance.
    * The database admin should be segregated from other IT function. DBA individuals are very knowledgeable super user and should not have any other IT duties.
    * Last but not the least about the main Uber user the Sys Admin (router, FW, Server, DT) should have a separate account when performing regular user function. These super users should be logged and audited on regular basis.

PCI view of Risk Assessment

Category: pci dss,Security Risk AssessmentDISC @ 11:02 pm
Information Security Wordle: PCI DSS v1.2 (try #2)

 

Organizations that need to comply with PCI-DSS need to create their own risk assessment methodology that works for their specific business needs, according to a new report by the Payment Card Industry Security Standards Council (PCI SSC).

PCI Risk Assessment Special Interest Group says When developing their own risk assessment methodology, organizations may consider adapting an industry-standard methodology that is most appropriate for their particular culture and business climate.

 
Key recommendations include:
 
• A continuous risk assessment process enables ongoing discovery of emerging threats and vulnerabilities, allowing an organization to mitigate such threats and vulnerabilities in a proactive and timely manner
 
• Risk assessments must not be used as a means of avoiding or bypassing applicable PCI DSS requirements (or related compensating controls)
 
• Organizations should implement a formalized risk assessment methodology that best suits the culture and requirements of the organization

PCI view of things:

Risk Assessment control selection and cost savings

Category: Risk Assessment,Security Risk AssessmentDISC @ 10:13 am

In risk management, risk treatment process begins after completion of a comprehensive risk assessment.
Once risks have been assessed, risk manager utilize the following techniques to manage the risks

• Avoidance (eliminate)
• Reduction (mitigate)
• Transfer (outsource or insure)
• Retention (accept and budget)

Now the question is how to select an appropriate control to avoid or reduce risk. While selecting appropriate control to mitigate and avoid risk we need to consider compensating control to cut cost and supplemental control to increase protection for sensitive or classified assets.

Compensating control is a safeguard or countermeasure is employed by an organization in lieu of recommended security control from standards such as ISO 27002 or NIST 800-53. Compensating control provides an equivalent or comparable protection for information system to the original control requirement form standard. For example, even though most standards recommend separation of duties, but for a small operation it might be an unacceptable cost to separate the duties of system administration and system auditing. In that case system owner can utilize compensating control such as strengthening the audit and personnel security.

On the other hand with supplemental control, the system owner may decide to supplement the control to achieve more protection for sensitive and classified assets. If there is high likelihood or magnitude of impact is high should a threat exploit a given vulnerability you might want to consider a supplemental control because overall risk is high. For example you might want to utilize defense in depth method to safeguard your crown jewel.

Implementing and monitoring security control can be expensive, system owner are pressured by management to look for cost savings without any reduction in the security posture of an organization. The system owner can either inherit the common controls or segment the system exposure to reduce cost and risks.
Common controls are the security controls which have been implemented by another information system that your system can utilize. Basically working with another system owner who has utilized some of the security controls need to be implemented in your system. For example utilize the corporate office base line hardening configuration for Windows and Unix system instead of developing your own. This will significantly reduce the cost of developing, testing and maintaining a secure baseline configuration.

Best and cheapest method of cost reduction is to segment the information system into multiple systems which will add different layers and levels of security into each system. Basically you put your crown jewel in multiple layers of security if one control breaks there is another control in place to monitor and protect your assets. This will allow the system owner to focus implementing higher security controls to the segment with most sensitive or classified information instead of entire system
