IT Security
IT Security is the set of all organizational, technical and procedural measures with which organizations protect their IT systems, data, applications and digital services. The aim is to ensure confidentiality, integrity and availability and to reduce risks from attacks, misconfigurations, data loss or unauthorized access. IT security is thus not a single tool, but an interplay of strategy, technologies, responsibilities and continuous improvement.
In practice, IT security ranges from protective measures for endpoints, networks, identities and cloud environments to attack detection, vulnerability management and incident response. It is particularly important not to view security events in isolation, but in the context of business processes, data and critical services. An overarching framework is provided by IT Security solutions; for organizations developing their security organization in a structured way, IT Security Consulting is also relevant.
IT security overlaps with terms such as cybersecurity, information security and risk management. While cybersecurity often emphasizes protection against digital attacks, IT security also encompasses operational stability, access control, policies, monitoring and recovery. A resilient security strategy therefore covers both preventive controls and reactive capabilities. These include, for example, a clear Security Posture, robust Endpoint Security and traceable Cyber Risk Management.
