Description: An incident is defined as an event that disrupts normal operations or poses a threat to the system. In the context of system management and security, an incident can range from technical failures to cyberattacks. Identifying and responding to these incidents is crucial for maintaining the integrity, confidentiality, and availability of systems. Incidents can be classified into various categories, including security incidents, which compromise information security, and others that may affect system performance. Incident management involves a structured process that includes detection, analysis, containment, eradication, and recovery, as well as documentation and post-incident learning to prevent future incidents. Tools like SELinux and AppArmor help mitigate risks by providing mandatory access controls, while monitoring systems like Nagios and Prometheus enable continuous observation of system status. In development environments, platforms like Azure DevOps facilitate incident management throughout the software lifecycle, ensuring that issues are addressed efficiently and effectively.
