öryggisábyrgð

Öryggisábyrgð, or "security responsibility" in Icelandic, refers to the principle of clearly defining and assigning accountability for the security of data, systems, and infrastructure within an organization or across a shared environment. This concept is particularly relevant in the context of cloud computing, where responsibilities are divided between service providers and customers to ensure robust security measures are implemented at all levels.

The framework of öryggisábyrgð is often structured around three primary models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). In each model, the provider assumes responsibility for different layers of security. For example, in IaaS, the customer typically manages security within the virtual machines, while the provider secures the physical infrastructure. In contrast, SaaS providers handle security at all levels, including application-level protections, reducing the customer’s burden.

The principle emphasizes transparency and collaboration between stakeholders to mitigate risks effectively. Organizations must align their internal security policies with the responsibilities outlined by their service providers to maintain a cohesive security posture. Öryggisábyrgð also aligns with broader cybersecurity frameworks, such as ISO/IEC 27001 and NIST, which advocate for shared accountability in safeguarding digital assets.

By adhering to öryggisábyrgð, entities can minimize vulnerabilities, enhance compliance, and foster trust in their security practices. This shared responsibility model ensures that security is not solely the provider’s or customer’s concern but a collective effort to protect sensitive information and maintain operational integrity.
