Systemsikkerhed

Systemsikkerhed refers to the practice of protecting computer systems and networks from theft, damage, or unauthorized access. It encompasses a broad range of technologies, processes, and practices designed to ensure the confidentiality, integrity, and availability of information. This includes safeguarding hardware, software, and data from malicious attacks, accidental damage, and natural disasters.

Key aspects of systemsikkerhed include network security, which focuses on protecting network infrastructure from intruders, and information security, which deals with protecting data from unauthorized disclosure or modification. Application security aims to prevent vulnerabilities in software applications that could be exploited. Endpoint security protects individual devices such as laptops and smartphones.

Common threats to systemsikkerhed include malware, phishing, ransomware, denial-of-service attacks, and insider threats. Organizations implement various measures to mitigate these risks. These measures often involve firewalls, antivirus software, intrusion detection systems, encryption, access controls, regular security audits, and employee training. The goal is to create a robust defense-in-depth strategy, where multiple layers of security work together to protect critical assets. Continuous monitoring and updating of security protocols are essential to adapt to evolving threats.
