What is a patch?

A patch is software that can be installed to fix a problem or vulnerability in a program. Patches are often temporary fixes between full releases of a software package.

Patches may do any of the following:

  • Fix a software bug
  • Install new drivers
  • Address new security vulnerabilities
  • Address software stability issues
  • Upgrade the software

What software needs to be patched?

All of it!  As vulnerabilities and errors in the software are discovered,  attackers often use the vulnerabilities in the software to hack into computers. One way to stop them is to keep all systems patched.

How do I patch?

At WaTech as well as most organizations, the patches are installed automatically.  Otherwise, the best thing to do is to research the software you use through the vendor website to find out how they distribute patches.  If possible, it is best to set up the updates to install automatically.
