In addition, the operating system also controls file access permissions and protects the integrity of the information.

4. Security and protection in an operating system

:

In an operating system,⁢⁣security and protection‌ are fundamental aspects that guarantee the confidentiality, integrity and availability of data and system resources. Safety refers to protection⁤ against external and internal threats that can compromise the integrity of the system, such as viruses, malware and cyber attacks. The protectionFor its part, it focuses on preventing users from performing actions that could negatively affect the system.

One of the most important security measures in an operating system is the access control. Through access control, different levels of permissions are established that limit access to system resources based on the roles and privileges assigned to users. This helps protect confidential information and prevent unauthorized users from making changes to the system.

In addition to access control, operating systems implement authentication protocols to verify the identity of users before allowing them to access the system. These protocols may include passwords, authentication two-factor ⁢or⁢ even biometrics. In this way, it is ensured that only authorized users can access the system and perform actions that affect its operation. Likewise, operating systems have encryption mechanisms to protect the confidentiality of stored data, thus preventing unauthorized access.
