February Security Tip: Why You Should Be Logging Website Security Activity

Security logging should be an essential part of your WordPress security strategy. Why?

Insufficient logging and monitoring can lead to a delay in the detection of a security breach. Most breach studies show that the time to detect a breach is over 200 days!

That amount of time allows an attacker to breach other systems, modify, steal, or destroy more data. For this reason, “insufficient logging” landed on the OWASP top 10 of web application security risks.

WordPress security logs have several benefits in your overall security strategy, helping you:

  1. Identity and stop malicious behavior.
  2. Spot activity that can alert you of a breach.
  3. Assess how much damage was done.
  4. Aid in the repair of a hacked site.

If your site does get hacked, you will want to have the best information to aid in a quick investigation and recovery.

The good news is that iThemes Security Pro can help you implement website logging. iThemes Security Pro’s WordPress security logs tracks all these website activities for you:
