Security Analytics FAQs

What are security analytics tools?

Security analytics tools take a longer look at system event data to spot patterns of behavior. This is different from traditional security software which examines each event in isolation. Modern cyberattacks utilize authorized user accounts and pore-existing system services to move around the network causing damage or stealing data. Security analytics tools aim to stop those activities and they can perform that search automatically or support manual investigations.

What is a soar tool?

SOAR stands for Security Orchestration, Automation, and Response. This type of system collects activity data from security systems, such as firewalls, assess it for indicators of compromise, and then sends out instructions to system management services to shut down threats. These systems also provide compliance reporting.

Is splunk a SIEM or soar?

Splunk is a real-time data analysis tool. The package can be used for a range of applications, such as marketing data analysis, or security scanning. The Splunk organization provides pre-written searches that create packages to adapt Splunk to specific needs and threw is an extensive library of security functions available for the tool. Mong the security services that you can implement with a Splunk package are a Security Information and Event Management (SIEM) package and a Security Orchestration, Automation, and Response (SOAR) service.
