SIEM Unveiled: A Simplified Guide to Security Information and Event Management – Advent Calendar 2023 Day9 #SIEM #SumoLogic

Background

In current world around 18 million cyberattacks occur every day, it is crucial for businesses to have strong cybersecurity. The creation of Security Information and Event Management (SIEM), a critical solution highlighted in the Gartner SIEM study and intended to improve IT security and vulnerability management, was prompted by this impending risk. SIEM, is based on the combination of Security Information Management (SIM) and Security Event Management (SEM), allows teams to monitor security in real-time and evaluate events while keeping track of security data logs for audit and compliance needs.

Introduction to SIEM

SIEM a potent tool that compiles security information from diverse systems within an organization, interconnected through a network. By continuously evaluating this data, SIEM empowers security teams to respond effectively to threats or security incidents, offering a comprehensive and well-rounded security solution. It carefully gathers logs from every office system, examines the log data to look for possible security risks, and then reports back on its findings.

Working of SIEM

Data Collection

SIEM's first step is the collection of security data from various sources across the network. This includes logs, alerts, and other events indicative of potential security incidents.

Data Correlation

Analyzing the collected data, SIEM identifies patterns, anomalies, and potential threats. It correlates events across different systems, actively searching for suspicious activity that could signify a breach or attack.

Alerting and Prioritization

Functioning as an alert system, SIEM notifies security teams of potential threats based on its analysis. Notably, it prioritizes alerts based on severity and risk level, ensuring that only the most critical issues are brought to attention.

Response and Remediation

Upon receiving an alert, the security team investigates the incident, gauges the extent of the threat, and takes swift action to mitigate or neutralize it. SIEM provides a centralized view of the incident, facilitating a coordinated and efficient response.
