Upplýsingaöryggi, or information security, refers to the practice of protecting information from unauthorized access, use, disclosure, disruption, modification, or destruction. It encompasses a wide range of measures, policies, and procedures designed to safeguard data and the systems that process, store, and transmit it. The primary goals of information security are to ensure confidentiality, integrity, and availability of information. Confidentiality means that information is accessible only to authorized individuals. Integrity ensures that information is accurate and complete, and has not been tampered with. Availability means that information and the systems that process it are accessible to authorized users when needed.

The field of upplýsingaöryggi is crucial in today's digital world, where vast amounts of data are generated, stored, and exchanged. Threats to information security can come from various sources, including cyberattacks, malware, phishing, social engineering, insider threats, and accidental data breaches. Organizations implement various security controls to mitigate these risks. These controls can be technical, such as firewalls, encryption, and antivirus software; administrative, such as security policies, training programs, and access control procedures; and physical, such as secure data centers and access restrictions to sensitive areas.

Effective upplýsingaöryggi requires a holistic approach that considers people, processes, and technology. It involves continuous monitoring, risk assessment, incident response planning, and regular updates to security measures to adapt to evolving threats. Compliance with relevant regulations and standards, such as GDPR or ISO 27001, is also a significant aspect of information security for many organizations.
