Security Assessment Methodologies

Assess security controls

This subtopic covers the different methodologies used to assess security controls and determine the effectiveness in mitigating threats to the organization's assets.
5 minutes 5 Questions

Security Assessment Methodologies are structured approaches to evaluate an organization's security posture. The primary methodologies include: 1. Vulnerability Assessment: Identifies and quantifies security vulnerabilities in systems and networks. It involves using automated tools to scan environments for known weaknesses, followed by analysis and remediation prioritization. 2. Penetration Testing: A simulated attack against systems to identify exploitable vulnerabilities. Types include black box (no prior knowledge), white box (complete information), and gray box (limited information). It goes beyond identification to demonstrate actual business impact. 3. Risk Assessment: Systematically evaluates security risks by identifying assets, threats, vulnerabilities, and calculating potential impacts. Methodologies include NIST SP 800-30, OCTAVE, and FAIR. 4. Security Audits: Systematic evaluation of security controls against established criteria or compliance requirements. May include physical security, policy reviews, and procedural controls evaluation. 5. Red Team Exercises: Advanced assessments where skilled security professionals simulate sophisticated threat actors to test detection and response capabilities. 6. Threat Modeling: Structured approach to identify potential threats during system design. Methods include STRIDE, DREAD, and PASTA. 7. Security Posture Assessment: Holistic evaluation of overall security effectiveness across people, processes, and technology. 8. Security Framework Assessments: Evaluations against industry standards like ISO 27001, NIST CSF, or CIS Controls. Effective security assessments require proper scoping, skilled personnel, management authorization, and careful planning to minimize operational impact. Results should provide actionable remediation guidance with appropriate risk prioritization.

Question 1

Which of the following is NOT an authentication factor?

Correct Answer: Authorization

Authorization is not an authentication factor, but it is a related process that follows authentication. The other answer choices are authentication factors.

Question 2

Which of the following attacks involves intercepting and altering communication between two parties, without their knowledge or consent?

Correct Answer: Man-in-the-middle (MitM) attack

A MitM attack involves intercepting and altering communication between two parties, which can result in data theft or other malicious activity. A DoS attack involves overwhelming a system or network with traffic or requests, making it unavailable for legitimate use. Phishing and social engineering attacks rely on tricking users into revealing sensitive information. A buffer overflow involves exploiting a program's memory allocation to execute malicious code.

Question 3

What is the purpose of a code review in the context of security assessments?

Correct Answer: To identify security vulnerabilities and coding errors in software

A code review is used to identify security vulnerabilities and coding errors in software that could potentially be exploited by attackers. By identifying these vulnerabilities and errors, the software can be made more secure.
