Patch management best practices

Patch management best practices

Technology is evolving fast and companies want to yield maximum from available resources. They are bringing a variety of devices creating complex architecture. It increases productivity but also provides a larger target. The time between discovery of a system vulnerability and the start of malicious exploits is getting shorter, often a matter of hours before attempted attacks. Only solutions to this problem is managing patches efficiently. 

Managing patches requires time and effort if it is not done by an automated Patch Management solution like InfraGuard. If done manually managing patches cost millions of dollars in patching activities. But with legal liability and fines attached it is unlikely that a company can get away with unmanaged patch management solution.

Here are some thumb rules of thumb to get you started:

  1. You start with assigning risk levels to each item in your inventory. For example, a server in your network that is not accessible from the Internet should not be as high a priority to patch. The more exposed to attack an item is, the faster it should be patched.
  2. Keep the number of versions of different applications or OSes to a minimum. The more versions of a piece of software you use, the higher the risk of exposure. It also creates large amounts of administrative overhead.
  3. Test patches before applying. Sometimes a patch cannot be applied right away. For example, a Java patch may break an existing business application. Changes need to be made to make the patch work.
  4. Organizations with an automated patch distribution mechanism often establish a short timeframe (average is about 48 hours to one week) for the testing and distribution of critical patches.

InfraGuard provides a comprehensive Patch Management solution that automatically filter patches based on severity level. It also lets you segregate servers based on OS, environments or tags. You can decide the patching cycle or set specific date and time for patching. There is one time setup and then just sit back and relax. InfraGuard will manage your patches for you and send you a summary when it’s completed.
