What’s the single most crucial factor in modern network security? Password management, data encryption, usage policies — each of these and nearly countless other elements all play a vital role in protecting your sensitive business and customer data from falling into unauthorised hands. But when it comes to effectively safeguarding your organisation’s digital assets, there is no single ingredient quite as essential as visibility. Unfortunately, as network size and complexity continue to expand, achieving that essential visibility becomes ever more difficult.
Security information and event management (SIEM, pronounced “sim”) is designed to address this and similar issues by gathering, aggregating, categorising, analysing and presenting log-security data from a diverse range of network sources. By bringing this information together into one security management system, SIEM provides IT and SecOps teams with the visibility they need to identify and respond to security threats in real time.
Simply put, SIEM puts network activity under a microscope, magnifying any activity that deviates from the norm and which might represent a potential breach in progress. This empowers organisations of all kinds to respond immediately to threats while maintaining strict data-compliance requirements.
