Security operations center definition
A Security operations center is a centralized facility or team within an organization responsible for monitoring, detecting, and responding to security incidents and threats. Its primary function is to continuously monitor an organization's information systems, network infrastructure, and digital assets to ensure the confidentiality, integrity, and availability of data.
A security operations center usually employs security analysts, incident responders, and other cybersecurity professionals. It is equipped with advanced security technology, like security information and event management systems, intrusion detection systems, and threat intelligence platforms. All of these are used to collect, correlate, and analyze security event logs and data from various sources in case of a security incident.
