Splunk Enterprise Security

Use Cases and Deployment Scope

We use Splunk for Security Logs. We basically monitor all Client logs whenever they use their cards.

Pros

  • Log collection
  • Visualization of the logs
  • Great filtering options of the logs.

Cons

  • Be more comprehensible
  • Provide more monitoring. Maybe an integration with Zabbix.

Return on Investment

  • It is hard to estimate considering it's not been a year that I've been working in the company, but it has for sure definitely helped to keep us reliable, trustworthy and secure in an indirect way. All of these help the bank I work for financially as well.

My Splunk review.

Use Cases and Deployment Scope

We deployed Cisco Splunk as a central SIEM to consolidate all of our logs from different vendors (Palo Alto, Fortinet, Aruba, Red Hat, Check Point...). Before Splunk, our analysts were juggling multiple disconnected tools across many dashboards and logs. Splunk fits our needs perfectly with real-time logging and alerting to prioritize incidents.

Pros

  • Risk alerting.
  • SOAR integration.
  • Threat management.
  • Ecosystem

Cons

  • Costs and license.
  • Onprem integration.
  • Out of the box detection.

Return on Investment

  • Tools consolidated.
  • False positive rate.
  • MTTD reduction.

The main SOC application

Use Cases and Deployment Scope

Splunk Enterprise Security is used as the primary SIEM solution in my company, used by tens of SOC users for the detection and investigation of suspicious activities

Pros

  • Detection of abnormal events at scale
  • Support of the SOC activity
  • Can be customized in depth

Cons

  • the mapping of the data with the Common Information Model is difficult to maintain over time
  • Data format changes are not detected automatically

Return on Investment

  • Splunk Enterprise Security support tens of SOC operators to track and investigate hundreds of security events every day.
  • The SOC is a critical activity. Splunk Enterprise Security is one of if not the best solutions that makes it possible, and at scale
