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.

Splunk ES, a great tool to use with some caveats!

Use Cases and Deployment Scope

I use the product to help monitor, analyze and potentially mitigate certain security issues that may come up. This includes acting as a secondary for escalations and looking at some alerts. I also use it to action on data that may be of use to our organization. It is helpful to organize alerting and easy to take action.

Pros

  • Monitoring log activity for potential security problems
  • The interface for investigations is pretty easy to use
  • Enjoy the high level detail the product gives for alerting
  • Nice playground for keeping track of investigations
  • Ease to create new notables to track further items.

Cons

  • Crazy awful latency when loading
  • Sometimes the events tab won't show any logs
  • Difficult to follow certain parts of investigations, but this is being addressed with Mission Control. (I'm talking about the original interface)
  • Confusion about where to easily navigate to view what items make up risk score as the interface can be confusing.
  • lowering risk score is extremely obnoxious.

Return on Investment

  • Fast MTTD but no specific numbers
  • Excellent integration with other tools so we don't have to pay for an additional service

My hands on experience with Splunk ES

Use Cases and Deployment Scope

Between our warehouse systems, fleet tracking, logistics portals and cloud apps, there's a flood of data every second. Splunk ES is the connector that pulls all that into one view. The company handles freight for a couple of government clients. We are therefore required to prove that all access and data transfers are monitored. Splunk's audit dashboards make that less painful

Pros

  • The dashboards are super flexible. We've built custom ones for different teams with so much ease
  • Correlation search feature is superb
  • Risk based alerting

Cons

  • The more data you feed it the more maintenance it needs and the cycle never stops but storage costs keep spiking.
  • Data onboarding is harder than it needs to be. We are always forced to contract partners whenever we're bringing in a lot of logs

Return on Investment

  • It saves the company millions by avoiding disruptions across logistics
  • My crew and I respond to threats so much faster with Splunk
