SIEM

What is SIEM?

SIEM (Security Information and Event Management) software centrally gathers, archives, and assesses logs spanning from perimeter to end user. It actively surveils for security risks in real time to swiftly detect, contain, and respond to attacks, offering comprehensive security reporting and compliance oversight.

In the event of a network attack leveraging SIEM, the software offers visibility into all IT elements (gateways, servers, firewalls, etc.).

Benefits of Using SIEM

SIEM software offers organizations a robust method for identifying the most recent security risks to their networks. It furnishes a comprehensive perspective on an organization's IT security through real-time reporting alongside in-depth analysis of security incidents. SIEM software aggregates event logs sourced from across the network, providing valuable forensic resources to IT personnel, which the software then aids in examining. Complete log compilation assists in meeting numerous compliance reporting obligations. Parsing and standardization align log messages from various systems into a unified data framework, facilitating the analysis of interconnected events logged in disparate formats. Correlation establishes connections between log events from different systems or applications, accelerating the identification and response to security threats. SIEM aggregation minimizes event data volume by merging duplicate event records and delivering reports on the correlated, aggregated event data in real-time, comparing it against long-term summaries.

Solving Problems Using SIEM

Numerous threats to network security are emerging and spreading rapidly. The proliferation of user mobility, remote locations, and the sheer volume of network-accessing devices has increased potential entry points into any network.

The advent of new applications and technologies not only creates risks but also invites novel attacks on networks. Within organizations, security breaches can remain undetected for extended periods, while some have dedicated IT departments focused on safeguarding malicious activities. Analyzing data from diverse sources is imperative for understanding network threats and devising appropriate responses.

• 1. Accountability through monitoring reports detailing actions and timestamps.

• 2. Transparency by providing insight into the security measures, business applications, and assets under protection.

• 3. Measurability through metrics and reports on IT risks within the company.
