How to organize a comprehensive process of vulnerability management

information security vulnerability management

To avoid serious security incidents, data leakage, business disruption, money loss and damage to your reputation, you should eliminate or remediate technical vulnerabilities as soon as possible. The sooner you address vulnerabilities, the lesser the probability of their exploitation, which could result in security incidents. Therefore, you should establish a continuous process for finding and remediation of the vulnerabilities in your applications, systems, equipment, and devices. If your IT infrastructure is big, and you do not know what is the best way to start, we will help you to set up vulnerability management operations in the following three steps. These recommendations are based on the best enterprise security practices and international standards such as ISO, PCI DSS, ITIL, and ISF SoGP.

Step 1. Plan the Vulnerability Management Process

Initiate a Vulnerability Management Process

Create a Vulnerability Management Policy or Regulation, which describes the process for managing technical vulnerabilities in your applications, systems, equipment, and devices. Namely, describe how you will:

Get an Appropriate Support for your Vulnerability Management Process
Define Scope

Ensure you covered all your systems, for example:

Assign Values of Criticality to your Assets

Define the value of your assets (applications, systems, equipment, and devices) before you begin any operations on vulnerability assessment. This will help evaluate the criticality of any found vulnerabilities and understand priorities and timescales of their remediation.

Step 2. Monitor your Infrastructure for Security Vulnerabilities

Investigate any Emerging Vulnerabilities at Early Stages
Scan and Analyze Vulnerabilities
Ensure the Vulnerability Scanning Itself is Secure

Step 3. Manage Patches

Remediate technical vulnerabilities by patch management process
Manage Possible Patching Issues
