What You Need To Know
Patch Management is the practice of keeping all computing devices up-to-date with the software and operating systems installed on them. Security vulnerabilities are constantly being discovered in software and updates (or patches) regularly fix these issues and therefore shut down these routes.
Modern software often has the ability to do this automatically and on a schedule, but older software may need to be updated manually. It is not only computers, tablets and mobile phones that require updating; printers, storage systems, firewalls and networking devices will have updates issued by vendors as well.
There should be a policy in place that details how software updates are to be dealt with. This will include a schedule of when checks are done for updates and a procedure for dealing with any exceptions and failures that may occur while updating.
Old software should be removed from the systems, this will stop any applications conflicting and causing errors.
All software that is used by the business must have a valid licence or the software is free to use.
