Tölvöryggis

Tölvöryggis is a term that broadly refers to computer security or cybersecurity in Icelandic. It encompasses the practices and technologies designed to protect computer systems, networks, and digital data from theft, damage, unauthorized access, or disruption. The field of tölvöryggis is vast and involves numerous disciplines, including network security, information security, application security, and data security.

The primary goals of tölvöryggis are to ensure the confidentiality, integrity, and availability of digital information. Confidentiality means that data is accessible only to authorized individuals. Integrity ensures that data is accurate and has not been altered without authorization. Availability means that systems and data are accessible and usable when needed by authorized users.

Common threats in the realm of tölvöryggis include malware such as viruses, worms, and ransomware, phishing attacks designed to trick users into revealing sensitive information, denial-of-service (DoS) attacks that aim to make systems unavailable, and various forms of hacking and data breaches. Protecting against these threats requires a multi-layered approach, often involving firewalls, antivirus software, intrusion detection systems, strong passwords, encryption, and regular security updates and patches. Education and awareness among users are also critical components of effective tölvöryggis.
