What is SIEM?
How does SIEM 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 using various analytical techniques, including log correlation and machine learning algorithms. Analyzing and correlating the logs helps SIEM solutions detect and prevent threats in an organization.
Why does your business need a SIEM solution?
- Monitors all network activities to help troubleshoot IT issues and ensures network security
- Prevents data breaches by identifying threat indicators at an early stage
- Discovers irregular user behavior patterns to catch sophisticated attacks so you can quickly launch a defense
- Issues real-time alerts for every security incident detected
- Helps businesses comply with IT regulations
- Prioritizes and resolves security incidents and threats
- Conducts forensic analysis, and speeds up post-incident recovery
- Assist with your compliancy requirements to do business
- Lowers your cyber insurance premiums
Functions of SIEM
Security information and event management (SIEM) solutions provide a holistic view of all the activities that happen in an IT infrastructure by monitoring network activities, and employing threat intelligence and user and entity behavior analytics (UEBA) to detect and mitigate attacks.
Log management
Log management involves the collection, normalization, and analysis of log data, and is used to gain better visibility into network activities, detect attacks and security incidents, and meet the requirements of IT regulatory mandates. For effective log analysis, SIEM solutions employ different processes such as log correlation and forensics, which help detect data breaches and attacks in real time. Log management also includes securely archiving log data to retain logs for a custom time period.
Incident management
A security incident is an event that is abnormal from regular activities in a network. An incident is capable of putting the sensitive data of an organization at risk and can lead to a data breach or an attack, but not always. Incident management includes detecting and mitigating security incidents. Incident detection is the process of identifying a security threat happening on a network. You can detect incidents using various techniques like log correlation, UEBA, and threat analytics. Incident resolution refers to solving an incident or an attack in the network and getting the network back to a functional state. SIEM solutions provide various workflows that can be automatically executed when an alert is triggered. These workflows help a great deal in preventing attacks from spreading laterally within the network.
