Scanner installed on a system for deep local analysis.
Vulnerability Management Cycle
Authenticated Scan
Scan performed with credentials for deeper system access.
Vulnerability Management Cycle
CVE ID
Unique identifier for publicly known cybersecurity vulnerabilities.
Vulnerability Management Cycle
CVSS Score
Standardized method for rating vulnerability severity.
Vulnerability Management Cycle
Vulnerability Assessment & Scanning Tools
To remember the scanning process: 'S.C.E.A.R.' - Scope, Configure, Execute, Analyze, Report. Think of it as 'Scanning Creates Excellent Actionable Reports!'
Vulnerability Management Cycle
Vulnerability Assessment & Scanning Tools
The exam expects you to know the difference between vulnerability scanning and penetration testing. Scanning IDENTIFIES vulnerabilities, while penetration testing EXPLOITS them to prove impact. Also, be familiar with common tools like Nessus for network scanning and Burp Suite for web applications.
Vulnerability Management Cycle
Vulnerability Assessment & Scanning Tools
Confusing vulnerability scanning with penetration testing; they are distinct activities.
Vulnerability Management Cycle
Vulnerability Assessment & Scanning Tools
Ignoring false positives in scan reports, which can lead to wasted remediation efforts.
Vulnerability Management Cycle
Vulnerability Assessment & Scanning Tools
Not performing authenticated scans when possible, which limits the depth of vulnerability detection.
Vulnerability Management Cycle
Black Box Test
Pen test with no prior knowledge of the target system.
Vulnerability Management Cycle
White Box Test
Pen test with full knowledge of the target system.
Vulnerability Management Cycle
Gray Box Test
Pen test with limited, partial knowledge of the target.
Vulnerability Management Cycle
Rules of Engagement
Document outlining scope, methods, and legal aspects of a pen test.
Vulnerability Management Cycle
Reconnaissance
Information gathering phase of a cyberattack or pen test.
Vulnerability Management Cycle
Exploitation
Process of taking advantage of a vulnerability to gain access.
Vulnerability Management Cycle
Ethical Hacking
Hacking performed with explicit permission to improve security.
Vulnerability Management Cycle
Penetration Testing Methodologies
Remember 'B-W-G' for Black, White, Gray: Black (no info, like a blind date), White (all info, like a close friend), Gray (some info, like an acquaintance).
Vulnerability Management Cycle
Penetration Testing Methodologies
The exam often distinguishes between vulnerability scanning (identifying potential weaknesses) and penetration testing (actively exploiting weaknesses to prove impact). Memorize the different types of pen tests (black, white, gray box) and their characteristics.
Vulnerability Management Cycle
Penetration Testing Methodologies
Confusing vulnerability scanning with penetration testing; scanning finds potential issues, pen testing exploits them.
Vulnerability Management Cycle
Penetration Testing Methodologies
Performing a penetration test without a clear 'Rules of Engagement' document, leading to legal issues.
Vulnerability Management Cycle
Penetration Testing Methodologies
Not acting on the findings of a penetration test, rendering the entire exercise pointless.
Vulnerability Management Cycle
Patch
Code changes to fix bugs, improve features, or address vulnerabilities.
Vulnerability Management Cycle
Zero-day
A vulnerability unknown to the vendor, actively exploited before a patch exists.
Vulnerability Management Cycle
Phased Deployment
Rolling out patches to small groups before broader release.
Vulnerability Management Cycle
Rollback Plan
A strategy to revert systems to a previous stable state if a patch fails.
Vulnerability Management Cycle
Service Pack
A collection of updates, fixes, or enhancements for a software product.
Vulnerability Management Cycle
Firmware Update
Software update for hardware devices, often critical for security/functionality.
Vulnerability Management Cycle
Patch Management Strategies
To remember the lifecycle: I Eat Apples Daily, Very Rarely. (Identify, Evaluate, Approve, Deploy, Verify, Report)
Vulnerability Management Cycle
Patch Management Strategies
The exam expects you to know the stages of the patch management lifecycle and the importance of testing. Keywords like 'vulnerability remediation', 'security updates', and 'configuration management' are key.
Vulnerability Management Cycle
Patch Management Strategies
Deploying patches to production without adequate testing, leading to system outages.
Vulnerability Management Cycle
Patch Management Strategies
Neglecting to patch non-critical systems, leaving them vulnerable to lateral movement.
Vulnerability Management Cycle
Patch Management Strategies
Failing to have a rollback plan, making recovery from bad patches difficult or impossible.
Vulnerability Management Cycle
Patching
Applying vendor-provided updates to software to fix bugs or vulnerabilities.
Vulnerability Management Cycle
Compensating Control
An alternative security measure used when a primary control is not feasible.
Vulnerability Management Cycle
Workaround
A temporary method to bypass a problem or vulnerability until a permanent fix.
Vulnerability Management Cycle
Verification
Confirming that a vulnerability fix has been successfully implemented and is effective.
Vulnerability Management Cycle
Continuous Improvement
Ongoing process of enhancing the effectiveness of the vulnerability management cycle.
Vulnerability Management Cycle
Prioritization
Ranking vulnerabilities based on severity, exploitability, and business impact.
Vulnerability Management Cycle
Configuration Change
Modifying system settings or parameters to enhance security or fix vulnerabilities.
Vulnerability Management Cycle
Remediation and Continuous Improvement
To REMEDIATE, remember: R-P-I-V-C. Rank, Plan, Implement, Verify, Continuously improve!
Vulnerability Management Cycle
Remediation and Continuous Improvement
The exam often tests your understanding of the full vulnerability management lifecycle. Be prepared to identify the correct sequence of steps and the purpose of each, especially the 'remediate' and 'verify' phases. Remember that remediation isn't just patching; it includes other strategies like configuration changes and compensating controls.
Vulnerability Management Cycle
Remediation and Continuous Improvement
Failing to verify that a vulnerability has been successfully remediated, leaving the system still exposed.
Vulnerability Management Cycle
Remediation and Continuous Improvement
Prioritizing vulnerabilities solely based on their technical severity without considering business impact or exploitability.
Vulnerability Management Cycle
Remediation and Continuous Improvement
Neglecting to document remediation actions, making it difficult to track progress or learn from past efforts.
