TS 13239

TS 13239 is a professional standard focused on the role of the computer network security specialist. It addresses both the definition and classification of the occupation and the way the specialist’s required characteristics are measured and evaluated. In general technical terms, network security is the set of methods and practices used to protect computer networks against unauthorized access, data leakage, service disruption, and misuse.

Occupation definition and classification framework

The standard treats computer network security specialist as a distinct professional role and clarifies its scope through a classification approach. In occupational standards, this is not only about naming the job title; it is about connecting the role to a common framework of knowledge, skills, and competence areas. This helps place network security in relation to network administration, system security, and IT support functions in a more consistent way.

Focus on measurement and evaluation

A notable feature of the standard is that it also covers the measurement and evaluation of the characteristics associated with this occupation. In general practice, this type of framework assesses technical knowledge, security awareness, problem-solving ability, and safe working habits in an organized manner. The key point here is that the standard addresses these evaluation areas; it should not be read as implying specific methods, tools, or performance thresholds beyond the provided scope.

From a broader technical perspective, network security brings together access control, authentication, authorization, firewalls, intrusion detection, patch management, and secure configuration. A computer network security specialist is the professional who connects these layers through design, implementation, monitoring, and improvement. By setting this role out as a professional standard, TS 13239 gives the occupation a shared basis for definition, classification, and evaluation.
