Does SIEM Replace Existing Security Tools?

Security information and event manager for credit unions from ongoing operations

At your credit union, you probably already have some security systems in place. If you’re considering a Security Information and Event Manager (SIEM) for your credit union, you may want to know how it will affect your existing security. Will a SIEM replace your existing security tools?

A SIEM may replace your existing tools, or it may not. It depends.

Regardless of how you protect your systems, a SIEM is designed to complement your existing setup. Whether you have no security system whatsoever, a bell attached to a string tied between two trees, archers in parapets, or a state-of-the-art cybernetic security AI equipped with lasers and a spare flux capacitor, an SIEM can help.

Straight Shootin’: How a SIEM Works with Existing Tools

The idea behind the SIEM is that it bolsters your existing tools in addition to providing tools that you still need. If you already have an intrusion detection system, an intrusion prevention system, or a firewall for example, the SIEM is designed to enhance those systems to increase efficacy.

Conversely, if you lack one of those systems at your credit union, the SIEM can perform that function on its own. It doesn’t just enhance the system—if you want, it is the system!

Will a SIEM Replace Security Tools if I Want it to?

Sure! Why not? But really, it’s up to your IT department.

If you have an existing firewall, and you want to work with a SIEM, you’ll have a few options.

  1. You could replace the existing firewall with a firewall service provided by the SIEM. You may choose this if you want to deal with a minimal amount of information or if you’re not happy with your current firewall.
  • You could keep the SIEM from performing the firewall service. Instead, you might choose to run only your original firewall.
  • You could allow the SIEM to augment the service provided by your internal firewall. This option might mean running the two services in tandem, so that two logs are created, building redundancy and stability into your security platform. We recommend this option.

Not only will a SIEM replace your security tools if you’d like, it will also allow your existing security controls to operate unimpeded should you so choose. To clarify, the above example works with more security tools than just a firewall.

Regardless of which security tools you currently have set up, your SIEM is designed to enhance those features or work around them. The overall effect is a net positive for credit union information security.

Is That a Yes or a No About Replacement?

Actually, it’s both. A SIEM is flexible enough to work with you and your IT department to best fit your Security Event and Information Management needs. You can customize your SIEM to deliver the kind of functionality that you’re looking for from your security and information suite.

If you’d like for the SIEM to replace your existing tools, you can engineer it to cover those duties. However, we think a SIEM works best when it can enhance you existing credit union information security tools.
