Patch management is responsible for the network and is also an essential function for those working in IT. There are many reasons why it is important and how it can lead to disruptions in the system or give hackers access to your systems.
At ITarian, we know that computers work because the software does different operations and functions. For example, operating systems are, in essence, a list of instructions, and the machine runs one after another to do a particular task. Vendors may need to update products to help improve the performance or address a security issue, so patch management is the process used to make changes to the program according to vendor specifications.
Why Do Vendors Update Software?
The biggest reason vendors update their software is because they notice errors or bugs in the system. Coding errors are typical and common, even though most people don't realize it. Programmers don't have years to go through every scenario that could happen with the software, so as they notice problems from various situations, they are patched or fixed. While most errors go unnoticed and pose no real problem, many can turn into bigger problems.
Risks To An Unpatched System
Systems should be regularly patched because if they aren't, they could experience many problems, including:
- Attacks – Hackers, viruses, malware, and worms can gain access, which can lead to:
- Stealing information
- Spying on the user and network
- Create rootkits and backdoors
- Change servers to display particular messages
- Access more important systems and potentially shut you down
- Denial – Hackers can crash your network or computer
- Stability – Cause systems to fail without an attack
- Performance – A slow program is one that doesn't get used
