Security information and event management systems have the capability of collecting security log events from numerous hosts within an enterprise and store their relevant data centrally. By bringing this log data together, these SIEM products enable centralized analysis and reporting on an organization’s security events. And that’s not everything – SIEM allows IT to monitor threats in real time and respond quickly to incidents so that a damage can be prevented. Of course, we should not take into account only the external attacks – IT needs a way to monitor user activity, so that it can minimize the risks from insider threat or accidental compromise.

Different kinds of organizations use SIEM systems for different purposes, so SIEM benefits vary across organizations. This article looks at the six top SIEM benefits.

  • Real-Time Monitoring
  • Incident Response
  • Threat Intelligence
  • Advanced Analytics
  • Advanced Threat
  • Detection

These capabilities give organizations the ability to use their SIEM for a wide range use of security use cases, as well as compliance. Let’s take a deeper look at each key capability of a SIEM solution.

  1. Real-Time Monitoring

The longer it takes to discover a threat, the more damage it can potentially inflict. IT organizations need a SIEM that includes monitoring capabilities that can be applied in real time to any data set, regardless of whether it’s located on-premises or in the cloud. In addition, that monitoring capability needs to be able to retrieve both contextual data feeds such as asset data and identity data, as well as threat intelligence feeds, which can be used to produce alerts. An SIEM is able to identify all the entities in the IT environment, including users, devices and applications as well as any activity not specifically attached to an identity. A SIEM is capable to use that data in real time to identify a broad range of different types and classes of anomalous behaviour. Once identified, that data needs to then be easily fed into workflow that has been set up to assess the potential risk to the business that anomaly might represent.

2. Incident Response

At the core of any effective incident response strategy is a robust SIEM platform that makes it possible not only to identify distinct incidents, but also provide the means to track and reassign them. SIEM is be able to provide other members of the organization with varying levels of access based on their roles. Other key capabilities include the ability to either manually or automatically aggregates events, support for application programming interfaces (APIs) that can be used to pull data from or push information to third-party systems. SIEM is also able to identify notable events and their status, to indicate the severity of events, to start a remediation process, and to provide an audit of the entire process surrounding that incident.

3. User Monitoring

User activity monitoring includes the ability to analyze access and authentication data, establish user context and provide alerts relating to suspicious behavior and violations of corporate and regulatory policies. It’s critically important when the user monitoring is extended to privileged users who are most often the targets of attacks. In fact, because of this risk, privileged user monitoring is a common requirement for compliance reporting in most regulated industries. For achieving those goals there are real-time views and reporting capabilities capable of leveraging a variety of identity mechanisms that can be extended to include any number of third-party applications and services.

4. Threat Intelligence

Threat intelligence makes it easier to recognize abnormal activity such as, for example, identifying outbound connections to an external IP address. With this level of threat intelligence, analysts have the information needed to assess the risks, impact and objectives of an attack that are critical to prioritizing an appropriate response.

Threat intelligence data could be ideally integrated with machine data generated by various types of IT infrastructure and applications to create watch lists, correlation rules and queries in ways that increase the success rate of early breach detection.

5. Advanced Analytics

SIEM is able to provide advanced analytics by employing sophisticated quantitative methods, such as statistics, descriptive and predictive data mining, machine learning, simulation and optimization, to produce additional critical insights.

6. Advanced Threat Detection

Security threats continually evolve. A good SIEM solution can adapt to new advanced threats by implementing network security monitoring, endpoint detection and behaviour analytics in combination with one another to identify and quarantine new potential threats. Most firewalls and intrusion protection systems can’t provide these capabilities on their own. The goal should be not only to detect threats, but also to determine the scope of those threats by identifying where a specific advance threat may have moved to after being initially detected, how that threat should be contained, and how information should be shared.

By describing all the above mentioned SIEM features and advantages, we can conclude that SIEM is considered not only as an issue of security or technology, but as an issue of business processes and productivity! SIEM introduction should be precisely planned in order to avoid false expectations or unexpected costs later on.
