So far we have only talk about security in the web, and internet related security issues, but there’re also other fields in which security should be applied. Operating System is an important example.

 

Operating System Security refers to the measurers and all the effort made by the developers to protect an OS. Do you recall the 3 big components abut computer security? Integrity, Availability, and Confidentiality. Well those three guys are the main components for the Operating system security as well.

 

The purpose of OS security is to protect the OS from malware, threats, and forbidden access. When someone unauthorized access to a computer, usually causes severe damage to the system and the data stored in it.

 

The most recommended methods to maintain security on your OS are the following:

 

  • Performing regular OS patch updates
  • Installing updated antivirus engines and software
  • Scrutinizing all incoming and outgoing network traffic through a firewall
  • Creating secure accounts with required privileges only (i.e., user management)

 

 

There’re also well know classification to determine the effectiveness of a system or a security solution.

 

  • Type A – Highest level
  • Type B
  • Type C
  • Type D – Lowest level (ms-Dos fall in this category)

 

Security applies to many fields and there are good and easy measures to prevent attacks from happening, keep updated and protected.
