We have a KB article on the topic of installing platform updates for your convenience. The article talks to how to install Platform Updates at a high level and will refer you to the appropriate product documentation for lower-level instructions.
These are the latest Monthly Platform Updates available. Monthly Platform Updates are also sometimes known as "Security Patches" or "Dated Platform Update Patches".
As a result of the migration from the defunct Layer 7 Support Portal to the CA Support Online (CSO) system, the download workflow changed for the products. At this time, we have the product baseline images in CSO, but not the Monthly Platform Updates as we are working through some workflow concerns. This document exists temporarily to fill the gap until all the Monthly Platform Updates exist in the CSO system.
