What is CIS (Center for Internet Security)?

CIS (Center for Internet Security) is a non-profit organization that provides security guidelines and standards for implementing cybersecurity improvements in organizations. CIS Benchmarks are a set of security recommendations developed to help organizations enhance cybersecurity and reduce the risk of various security threats. These recommendations are available for multiple operating systems, including Linux, as well as other technologies.

CIS and Linux

The CIS Linux Benchmark provides organizations with concrete and practical recommendations that can be applied to Linux environments. These recommendations can be used to reduce cybersecurity threats and enhance the security of Linux systems. The benchmark includes the following key aspects:

User management: Instructions for managing user rights, requiring strong passwords, and locking user accounts.

Network settings: Recommendations for configuring the firewall, restricting services, and using secure network protocols.

System settings: Instructions on installing security updates, monitoring log information, and tightening system configuration.

File and directory permissions: Recommendations for defining and reviewing file and directory permissions.

Monitoring log data: Instructions for collecting and analyzing log data to detect potential cybersecurity deviations.

By following these recommendations, organizations can improve the cybersecurity of their Linux systems and effectively respond to modern cybersecurity threats. The recommendations provide practical guidance and methods to reduce vulnerabilities and enhance overall security practices.
