Security management is the process of controlling access to assets in the network. Data security can be achieved mainly with [[authentication]] and [[encryption]]. [[Authorization]] to it configured with [[Operating system|OS]] and [[Database management system|DBMS]] [[access control]] settings.

Security management is not only concerned with ensuring that a network environment is secure, but also that gathered security-related information is analyzed regularly. Security management functions include managing network authentication, authorization, and auditing, such that both internal and external users only have access to appropriate network resources. Other common tasks include the configuration and management of network firewalls, intrusion detection systems, and security policies (such as access lists). Network elements keep log files, which are examined during a [[security audit]]. Many telecommunications network elements produce a security alarm<ref>{{cite web |last1=ITU-T |title=Recommendation X.736 : Information Technology - Open Systems Interconnection - Systems Management: Security alarm reporting function |url=https://www.itu.int/rec/T-REC-X.736/en |accessdate=5 September 2019}}</ref> when a security violation is suspected.
