ITnät

ITnät is a term used to describe the information technology network that connects devices, services, and users within an organization or institution, with particular use in Swedish-speaking contexts. It encompasses local area networks, wide area networks, data centers, cloud connections, and remote access infrastructure, enabling communication, data exchange, and collaborative work.

Typical components include wired and wireless networks, servers, storage, virtualization platforms, network security appliances, and identity and access management systems. The network often relies on layered architecture with core, distribution, and access layers, plus DMZs for exposed services and segmentation to limit lateral movement in case of a breach.

Security and governance are central. ITnät is usually governed by policies on user access, device management, and data protection. Common practices include network segmentation, firewalls, intrusion detection systems, encryption, patch management, and incident response planning. Auditing and change management align with IT governance frameworks such as ITIL or ISO 27001 in many organizations.

Access is controlled through authentication methods such as passwords, multi-factor authentication, and single sign-on. Remote access may use VPNs or zero-trust architectures. User roles and least privilege are enforced for administrative accounts and critical infrastructure.

Interoperability is supported by standard networking protocols and services, including IP, DNS, DHCP, VPN technologies, and cloud connectors. Documentation, monitoring, and change management tools are typically used to maintain network reliability and performance.
