Security information and event management (SIEM) software helps IT security professionals protect their enterprise network from cyberattacks. A SIEM tool gathers log data from all infrastructure components in an organization—routers, switches, firewalls, servers, personal computers and devices, applications, cloud environments, and more—analyzes the data, and provides insights to security administrators for effective mitigation of security attacks.

How does a SIEM solution work?

SIEM solutions collect logs, the time-stamped records of events generated by every device and application in the network, using both agentless and agent-based mechanisms. Once the logs are aggregated within the SIEM software, they are normalized and analyzed using correlation, machine-learning algorithms, and other techniques to detect suspicious activities.

Benefits of SIEM  

 

Faster and more efficient
security operations

Helps spot and prioritize the resolution of security threats; automates responses to known threats and improves the mean time to resolve (MTTR) an attack

 

Optimized network operations

Monitors all network activities and stores log data for root cause analysis and troubleshooting

 

Cyber resilience

Helps organizations quickly get back to business after a breach or security incident with log forensics and impact analysis, and instantly generates incident reports to avoid compliance penalties

 

Security orchestration

Integrates with other IT solutions of your network and centralizes security management

 

Compliance adherence
and management

Maps the requirements of various compliance regulations with security operations; audit-ready compliance report templates and compliance violation alerts to help in complying with regulatory mandates

Breaking down
SIEM functions

SIEM is built on two main functions

         
  • 1

    Security information management (SIM)

    SIM involves the collection of all network activities. This can range from log data collected from servers, firewalls, domain controllers, routers, databases, and FetFlow to unstructured data present in the network, such as in emails.

    Log data can be collected using two techniques—agentless and agent-based collection.

    • Agent-based log collection

      This method requires the deployment of an agent on every device. The agent collects logs, then parses and filters them before returning the logs to the SIEM server. This technique is mainly used in a closed and secured network—such as a demilitarized zone—where communication is restricted.

    • Agentless log collection

      This is the more frequently used method in which logs generated by devices are automatically collected by the SIEM server using a secure communication channel, such as a specific port using secured protocols.

  • 2

    Security event management (SEM)

    SEM refers to the analysis of the collected data. The data is analyzed using various techniques, alerts about security events are sent, and workflows are initiated to respond to any abnormal behavior.

SIEM use cases

  •  

    Threat detection

    Detect security threats using rule-based log correlation engines, threat modeling framework (MITRE ATT&CK) integrations, and anomaly detection.

     
  •  

    Anomaly detection

    Spot advanced persistent threats and sophisticated attacks using AI- and ML-driven user and entity behavior analytics (UEBA).

     
  •  

    Cloud security

    Protect multi-cloud environments by auditing security events and enforcing security policies for access to cloud resources.

     
  •  

    Compliance auditing

    Prove compliance with regulatory mandates and generate audit-ready reports in a few clicks.

     
  •  

    Security analytics

    Continuously monitor security events from different sources across the network with analytical dashboards.

     
  •  

    Endpoint protection

    Monitor and protect your endpoints proactively from cyberthreats.
