Patch Management

Patch management is identifying, acquiring, testing, and deploying software updates—commonly called patches—to fix known vulnerabilities, bugs, or performance issues in applications, operating systems, and firmware. It ensures systems remain secure, functional, and compliant with internal and external requirements.

Patch management is a foundational cybersecurity practice that helps organizations reduce their attack surface and protect against known exploits.

Unpatched software is one of the most common entry points for cyberattacks. Exploits targeting known vulnerabilities—often published in CVE databases—are readily available and widely used by threat actors. Without timely patching, organizations risk:

• Data breaches and ransomware attacks
• Operational downtime and performance degradation
• Non-compliance with standards like PCI-DSS, HIPAA, and NIST
• Reputational and financial harm due to preventable security failures

Patch management mitigates these risks by ensuring known issues are resolved before they can be exploited.

A robust patch management process typically includes:

• Asset Discovery: Identify systems, applications, and devices in your environment.
• Patch Identification: Monitor vendors, threat feeds, and vulnerability databases for new patches.
• Patch Testing: Verify patch compatibility and impact in a test environment.
• Deployment Scheduling: Determine patch rollout timelines based on risk severity and business constraints.
• Patch Deployment: Use automated tools or manual processes to apply updates.
