Companies collect and manage large amounts of data that require robust systems to analyse and detect security breaches. A security information and event management (SIEM) tool can help organisations be proactive and mitigate such risks. Learning about these tools may help you choose a suitable tool for the organisation's information system security requirements. In this article, we discuss the definition of SIEM software and its benefits, essential features and 11 popular tools to secure organisational data.

What are SIEM tools?

SIEM tools are a security solution that helps organisations identify threats, vulnerabilities and lapses in the security systems that may disrupt information security and workflow efficiency. These tools collect logs and events data from various applications and security devices in the organisation into one centralised system. A SIEM tool then segregates the activities across the network according to pre-defined rules and raises alerts accordingly to define the threat level. They offer real-time monitoring of data, which helps improve investigative efficiency and reduces false positives and events of security breaches.

Essential SIEM software features

The requirements and expectations from a SIEM tool may differ from one organisation to another. Certain features build any SIEM system and are essential to evaluate before investing in the tool. Here are some of the essential features to look out for:

  • Log data management: It collects real-time data for multiple sources and categorises them accordingly. Analysing the data and correlating it helps improve the efficiency of the security systems and allows teams to respond faster to threats.

  • Threat intelligence: SIEM software may have proprietary or open-source intelligence feeds to make the system robust and responsive to modern threats. These tools may also allow you to generate reports to analyse the breach or even recreate it to understand system response during a malicious cyber-attack.

  • Analytics: The analytical capabilities differ in SIEM software. Tools with artificial intelligence and machine learning capabilities increase the efficiency of the systems and allow organisations to perform sophisticated and complex investigations.

  • Dashboard: A SIEM tool collects data from multiple sources and provides a simple and user-friendly dashboard to help analysts understand and interpret the data. SIEM software offers a customisable view that updates in real-time, along with data visualisation capabilities.

  • Regulatory compliance: Regulatory requirements differ from one industry to another, making it essential for SIEM software to provide several compliance options. Organisations evaluate these capabilities and prioritise auditing and reporting compliance before investing in a SIEM tool.

  • Adaptability: Organisations may begin with basic security requirements that change as they grow. It is vital that SIEM software is easy to scale, can integrate with existing systems and meet the information security requirements of the company.

Benefits of SIEM tools

As organisations expand, it also increases the amount of data they collect. In such cases, SIEM software helps enterprises manage security data using one dashboard. Some other benefits of SIEM software include:

Increase security efficiency

SIEM software allows active monitoring of the entire infrastructure, which helps in reducing the time required to identify and react to security threats. It offers one centralised dashboard, which eases the analysis of files. The reduced time to track vulnerabilities allows employees to devise effective counter-strategies to avert security breaches.

Compliance auditing

An enterprise uses several security tools at various levels in the organisation. A SIEM system centralises data collection and storage, enabling seamless compliance auditing and reports across the entire network. Advanced automation systems reduce reliance on external resources to audit and help display the security reports on one dashboard.

Detect advanced threats

System information management tools often use integrated threat intelligence and artificial intelligence (AI) to update themselves to detect more advanced threats and security breach patterns to ensure system information security effectively. These systems can identify and mitigate several security breaches, including insider threats, phishing and SQL injections. A SIEM tool can help manage networks that generate unusual traffic or attempt a data theft.

Cost-efficient

SIEM offers an integrated view of system data and performs several other operations, such as analysis and data segregation. It helps reduce the dependence on multiple systems and human involvement in information security. The entire process makes cybersecurity more cost-effective for the organisation.
