Saving Money with IT Security Processes. Example 12/26: Avoid Website Defacement with Vulnerability Management

Article number 12 in a series dedicated to giving examples of the way IT security processes can help your company save money.

Vulnerability Management is the process that helps your information system stay up to date with patches that fix vulnerabilities in the software you use. One striking example is: with correct Vulnerability Management, you won't get any of your websites defaced.

Please note that it can't be reduced to just using another piece of software to update it all. No single piece of software can possibly fix everything on a regular basis, nor can it fix problems with the best acumen. It's the Vulnerability Management process. It does the following:

• Technological Watch for all currently used pieces of software and technologies. This means subscribing to newsletters or feeds from every single related vendor and reading them.
• Whenever a new vulnerability has been spotted, identify whether the company is affected or not.
• If it's affected, check how much it would cost to suffer from the exploitation of the vulnerability and compare with the cost of applying the patch or workaround.
• Have it put in action.

The Vulnerability Management process is not always identified as a process per se, but sometimes distributed in the Technological Watch and Patch Managements processes.
