Threats, Vulnerabilities, and Mitigations

Exam tip

Application Vulnerabilities: Overflows, SQLi, XSS

The exam often presents scenarios where an attacker manipulates input fields. Keywords like 'unexpected database errors,' 'pop-up scripts,' or 'application crashes after long input' are strong indicators of these vulnerabilities.

To remember the risk strategies: A.T.M.A. (Avoid, Transfer, Mitigate, Accept). Think of an 'ATM' as a place where you manage your financial risks!

Security Program Management and Oversight

Exam tip

Governance Frameworks and Risk Management Basics

The exam often asks about the purpose of specific frameworks. Remember COBIT for IT governance, ITIL for IT service management, and ISO/IEC 27001 for information security management systems.

Security Program Management and Oversight

Common mistake

Governance Frameworks and Risk Management Basics

Confusing governance frameworks with compliance regulations; frameworks are guides, regulations are mandates.

Security Program Management and Oversight

Common mistake

Governance Frameworks and Risk Management Basics

Not understanding that risk acceptance is a deliberate, informed decision, not just ignoring a risk.

Security Program Management and Oversight

Common mistake

Governance Frameworks and Risk Management Basics

Memory trick

Quantitative Risk: ALE, SLE, and ARO Calculations

SLEepy AROma makes you ALErt! SLE = AV x EF, ARO is the frequency, ALE = SLE x ARO.

Security Program Management and Oversight

Exam tip

Quantitative Risk: ALE, SLE, and ARO Calculations

The exam often presents scenarios where you need to calculate SLE, ARO, or ALE. Remember the formulas: SLE = AV * EF, and ALE = SLE * ARO. Look for keywords like 'asset value,' 'percentage lost,' 'occurs annually,' or 'expected frequency.'

Security Program Management and Oversight

Common mistake

Quantitative Risk: ALE, SLE, and ARO Calculations

Confusing Exposure Factor (EF) with the actual monetary loss; EF is a percentage.

Security Program Management and Oversight

Common mistake

Quantitative Risk: ALE, SLE, and ARO Calculations

Incorrectly calculating ARO, especially when events occur less frequently than once a year (e.g., once every 5 years is ARO 0.2, not 5).

Security Program Management and Oversight

Common mistake

Quantitative Risk: ALE, SLE, and ARO Calculations

Forgetting to convert the Exposure Factor percentage into a decimal before multiplying (e.g., 50% is 0.5).

Remember 'VENDORS' for key Third-Party Risk areas: Vulnerabilities, External access, Non-compliance, Data handling, Operational impact, Reputation, Security controls.

Security Program Management and Oversight

Exam tip

Third-Party Risk, Compliance, and Audits

The exam often tests your understanding of what constitutes a third party and the types of reports used to assess their security, such as SOC 2 Type 2. Memorize that SOC 2 reports focus on security, availability, processing integrity, confidentiality, and privacy.

Security Program Management and Oversight

Common mistake

Third-Party Risk, Compliance, and Audits

Assuming a third party's security is 'good enough' without verification. Always verify through audits or reports.

Security Program Management and Oversight

Common mistake

Security Program Management and Oversight

Exam tip

Penetration Testing and Security Assessments

The exam often tests your ability to distinguish between vulnerability scanning and penetration testing. Remember that scanning IDENTIFIES, while pen testing EXPLOITS. Also, know the different 'box' types (black, white, gray) and what level of information they imply for the tester.

Security Program Management and Oversight

Common mistake

Penetration Testing and Security Assessments

Confusing vulnerability scanning with penetration testing; scanning finds, pen testing exploits.

Security Program Management and Oversight

Common mistake

Penetration Testing and Security Assessments

Not clearly defining the scope and rules of engagement before a penetration test, leading to legal or operational issues.

Security Program Management and Oversight

Common mistake

Security Program Management and Oversight

Common mistake

Security Awareness and Training Programs

Treating security awareness as a one-time event rather than a continuous process.

Security Program Management and Oversight

Common mistake
