In the world of business cybersecurity, the powerful technology known as “Security Information and Event Management” is sometimes thwarted by the most unexpected actors—the very people setting it up. Security Information and Event Management—or SIEM—is a term used to describe data-collecting products that businesses rely on to make sense of everything going on inside their network, in the hopes of catching and stopping cyberattacks. SIEM systems can log events and information across an entire organization and its networks. When properly set up, SIEMs can collect activity data from work-issued devices, vital servers, and even the software that an organization rolls out to its workforce. The purpose of all this collection is to catch what might easily be missed. For instance, SIEMs can collect information about repeated login attempts occurring at 2:00 am from a set of login credentials that belong to an employee who doesn’t typically start their day until 8:00 am. SIEMs can also collect whether the login credentials of an employee with typically low access privileges are being used to attempt to log into security systems far beyond their job scope. SIEMs must also take in the data from an Endpoint Detection and Response (EDR) tool, and they can hoover up nearly anything that a security team wants—from printer logs, to firewall logs, to individual uses of PowerShell. But just because a SIEM can collect something, doesn’t necessarily mean that it should. Log activity for an organization of 1,000 employees is tremendous, and the collection of frequent activity could bog down a SIEM with noise, slow down a security team with useless data, and rack up serious expenses for a company. Today, on the Lock and Code podcast with host David Ruiz, we speak with Microsoft cloud solution architect Jess Dodson about how companies and organizations can set up, manage, and maintain their SIEMs, along with what advertising pitfalls to avoid when doing their shopping. Plus, Dodson warns about one of the simplest mistakes in trying to save budget—setting up arbitrary data caps on collection that could leave an organization blind. “A small SMB organization … were trying to save costs, so they went and looked at what they were collecting and they found their biggest ingestion point,” Dodson said. “And what their biggest ingestion point was was their Windows security events, and then they looked further and looked for the event IDs that were costing them the most, and so they got rid of those.” Dodson continued: “Problem was the ones they got rid of were their Log On/Log Off events, which I think most people would agree is kind of important from a security perspective.” Tune in today to listen to the full conversation.
