Vulnerability Management
Simple Definition for Beginners:
Vulnerability Management is the process of identifying, assessing, prioritizing, and mitigating security vulnerabilities in software, systems, and networks to reduce the risk of exploitation.
Common Use Example:
A company uses vulnerability management tools to scan its network for vulnerabilities regularly, assess their severity, and prioritize patches and updates to secure critical systems.
Technical Definition for Professionals:
Vulnerability Management is a systematic approach to identifying, assessing, prioritizing, and mitigating vulnerabilities in software applications, IT infrastructure, and network environments. The process involves several key steps:
- Vulnerability Identification: Using automated tools, manual techniques, and threat intelligence to identify known and potential vulnerabilities in systems, applications, and devices.
- Vulnerability Assessment: Assessing the severity, impact, and exploitability of identified vulnerabilities based on factors such as CVSS scores, threat vectors, and business impact.
- Risk Prioritization: Prioritizing vulnerabilities based on their criticality, potential impact on operations, sensitive data exposure, regulatory compliance requirements, and likelihood of exploitation.
- Patch Management: Implementing patches, updates, security fixes, and configuration changes to remediate identified vulnerabilities and reduce exposure to security risks.
- Continuous Monitoring: Monitoring and scanning systems continuously or periodically to detect new vulnerabilities, configuration drift, and emerging threats.
- Incident Response: Developing incident response plans, playbooks, and procedures to respond promptly and effectively to vulnerabilities that pose immediate risks or are actively exploited.
- Reporting and Remediation: Generating vulnerability reports, metrics, and dashboards to track progress, measure effectiveness, and ensure timely remediation of identified vulnerabilities.
- Compliance and Auditing: Ensuring compliance with security standards, regulatory requirements, industry best practices, and internal policies related to vulnerability management.
Vulnerability Management aims to reduce the attack surface, improve security posture, enhance incident prevention and response capabilities, and mitigate the risk of security breaches and data compromises.
