An essential component in any cybersecurity solution is the detection of potential and actual threats. To effectively set up threat detection, you need accurate forensic information about applications, protocols and service types. Security information and event management (SIEM) enables your company to recognize security threats and react accordingly by putting a system in place which aggregates, analyses and reports security information. A SIEM application collects logs from databases, applications, operating systems, servers, the cloud, network devices, network gateways and end-user devices as well as flow-based monitoring systems, such as Netflow, IPFIX, jflow and sflow. Data from security devices, such as firewalls and IDS, is analyzed using a set of predefined rules and algorithms to identify attacks and threats. Security teams investigating security incidents use data captured by SIEM to run forensics and root-cause identification. Deep packet inspection (DPI) enables a thorough scan of every data packet. By providing granular traffic insights, DPI engines help you to augment your SIEM solution with real-time visibility into all network flows – even encrypted traffic.
