Vulnerability Management Interview Questions: Fundamentals

Interviewers may ask you about the basic concepts of vulnerability management, such as vulnerability assessment, risk assessment, and patch management.

1) What is a vulnerability assessment and how does it differ from penetration testing?

A vulnerability assessment is a systematic process of identifying and quantifying security weaknesses in systems, applications, and networks. It’s like a comprehensive inspection that reveals potential entry points for attackers. Think of it as a doctor performing a check-up to identify health issues.

Penetration testing, on the other hand, goes a step further. It simulates real-world attacks to actively exploit identified vulnerabilities and determine the extent of potential damage. This is analogous to a specialist conducting diagnostic tests to understand the severity of a medical condition.

Key Differences:

Feature	Vulnerability Assessment	Penetration Testing
Objective	Identify vulnerabilities	Exploit vulnerabilities
Scope	Broad, covering many systems	Focused on specific targets
Methodology	Automated scans and manual checks	Manual techniques and specialized tools
Outcome	List of vulnerabilities with severity levels	Report detailing exploited vulnerabilities and their impact

2) Explain the difference between a vulnerability, threat, and risk.

These three terms are often used interchangeably, but they have distinct meanings in the context of cybersecurity:

Vulnerability: A weakness in a system, process, or design that could be exploited by a threat. Think of it as a crack in a wall.
Threat: Any potential event or action that could exploit a vulnerability and cause harm. This could be a malicious actor, a natural disaster, or even an accidental error. Imagine a person with a hammer who could use it to exploit the crack in the wall.
Risk: The likelihood that a threat will exploit a vulnerability and the resulting impact. It’s the combination of the likelihood and consequence of an event. In our example, the risk would be the probability that the person with the hammer will actually use it to break the wall and the damage that would result.

3) What are the different types of vulnerabilities?

Vulnerabilities can be categorized based on where they reside:

Network Vulnerabilities: These affect network devices and protocols, such as routers, switches, firewalls, and VPNs. Examples include misconfigured firewalls, weak encryption protocols, and outdated firmware.

Application Vulnerabilities: These exist within software applications and can be exploited to gain unauthorized access, manipulate data, or disrupt functionality. Examples include SQL injection flaws, cross-site scripting (XSS) vulnerabilities, and buffer overflows.

4) Describe the CVSS scoring system and its components.

The Common Vulnerability Scoring System (CVSS) is an industry-standard method for assessing the severity of security vulnerabilities. It provides a numerical score from 0 to 10, with higher scores indicating greater severity. The CVSS score is based on several metrics, grouped into three categories:

Base Metrics: These reflect the inherent characteristics of the vulnerability, such as attack vector, attack complexity, required privileges, user interaction, scope, confidentiality impact, integrity impact, and availability impact.
Temporal Metrics: These capture the time-dependent characteristics of the vulnerability, such as exploit code maturity, remediation level, and report confidence.
Environmental Metrics: These consider the specific environment in which the vulnerability exists, such as security requirements, modified attack vector, and modified scope.

Understanding the CVSS scoring system helps prioritize vulnerability remediation efforts based on the severity and potential impact of each vulnerability.

5) What are the common vulnerability databases?

Several publicly available databases provide comprehensive information about known vulnerabilities:

CVE (Common Vulnerabilities and Exposures): Maintained by MITRE, CVE is a dictionary of publicly known security vulnerabilities. It provides a standardized naming system for vulnerabilities, making it easier to share information and track them across different security tools and databases.
NVD (National Vulnerability Database): Operated by NIST, NVD provides detailed information about CVEs, including CVSS scores, vulnerability descriptions, known exploits, and mitigation strategies.
Exploit Database: This database catalogs exploits and proof-of-concept code for known vulnerabilities. It’s a valuable resource for security researchers and penetration testers.
