What is patching and why is it important?

Patches are nothing but pieces of software code that are written to fix a bug in a software application, that might lead to a vulnerability. Such vulnerabilities in any application are loop holes for attackers to get their hands on business critical data and information. So it is highly crucial to keep all the applications in a network updated to its latest versions. Updating applications in mobile phones and laptops also work in the same manner by preventing theft of personal data, through security flaws.

What kind of patch updates are released during Patch Tuesday?

Predominantly security patch updates of varying severity like Critical, Important, Moderate & Low are labeled and released. Effective Windows patch management involves prioritizing these based on severity, automating deployment, and ensuring rollback or compatibility testing. It is always a best practice to prioritize your patching based on the severity level mentioned.
