sikkerhedshændelse

A sikkerhedshændelse, or security incident, refers to any event that compromises the confidentiality, integrity, or availability of an information system or the data it holds. This can range from unauthorized access to systems, data breaches, denial-of-service attacks, malware infections, or even accidental disclosure of sensitive information. The impact of a security incident can vary greatly, from minor disruptions to significant financial losses, reputational damage, and legal consequences.

Organizations typically establish incident response plans to address security incidents. These plans outline the steps to be taken before, during, and after an incident. Pre-incident activities include risk assessment, vulnerability management, and security awareness training. During an incident, the focus is on containment, eradication of the threat, and recovery of affected systems. Post-incident activities involve analysis to understand the cause, lessons learned, and implementation of improvements to prevent future occurrences.

The detection of a security incident can occur through various means, including security monitoring tools, user reports, or external notifications. Prompt and effective incident response is crucial to minimize the damage and restore normal operations. This often involves collaboration between IT security teams, legal departments, and potentially external cybersecurity experts. Compliance with data protection regulations, such as GDPR, also plays a significant role in how security incidents are handled and reported.
