"System and Security" refers to the measures and protocols put in place to protect computer systems and networks from unauthorized access, damage, or theft. This includes hardware and software solutions designed to safeguard data integrity and ensure the availability of resources. Key components often involve firewalls, antivirus software, and encryption techniques. Effective system security also encompasses user authentication and access controls, which help verify the identity of users and restrict their access to sensitive information. Regular updates and patches are essential to address vulnerabilities, while security policies guide organizations in maintaining a secure environment for their operations and data management.
