How to Instantly Secure Log4j

secure log4j

The log4j vulnerability was announced on December 10, 2021, and ranks as one of the worst in history. How to secure log4j? The best resolution is to upgrade to a secure version. However, sometimes that is not possible, or at least it takes time. In these scenarios, runtime protection for log4j or other vulnerabilities can be a lifesaver.

In organizations that have hundreds or thousands of applications, it can take days or even weeks of an all-out effort to upgrade these applications. Or it could be that the vulnerable applications are supplied by a vendor, and the vendor does not have a fix immediately available. The runtime protection can be applied with a few clicks of a mouse and save you a lot of time. This video below walks you through how that works.

How to secure log4j instantly at runtime?

In this video, Julius Musseau and Delan Elliott show how:

  • How to access to a vulnerable library can be controlled
  • Either for the full library or surgically for just the method(s) that is at the root of the vulnerability.
  • This enables the organization to respond instantly to new vulnerabilities.
  • It applies to vulnerabilities such as CVE-2021-44228, and CVE-2021-45046
  • But can be applied to any Java based vulnerability.
