The typical SIEM implementation suffers from TMI, TLA (Too Much Information, Too Little Analysis). And if any organization that’s recently been in the news knows this, itâs the National Security Agency (NSA). The Wall Street Journal carried this story quoting William Binney, who rose through the ranks at the National Security Agency (NSA) over a 30 year career, retiring in 2001. âThe NSA knows so much it cannot understand what it has,â Binney said. “What they are doing is making themselves dysfunctional by taking all this data.”
Most SIEM implementations start at this premise – open the floodgates, gather everything because we are not sure what we are specifically looking for, and more importantly, the auditors donât help and the regulations are vague and poorly worded.
Lt Gen Clarence E. McKnight is the former head of the Signal Corps and opined that “The issue is a straightforward one of simple ability to manage data effectively in order to provide our leaders with actionable information. Too much raw data compromises that ability. That is all there is to it.”
A presidential panel recently recommended the NSA shut down its bulk collection of telephone call records of all Americans. It also recommended creation of “smart software” to sort data as it is collected, rather than accumulate vast troves of information for sorting out later. The reality is that the collection becomes an end in itself, and the sorting out never gets done.
The NSA may be a large, powerful bureaucracy, intrinsically resistant to change, but how about your organization? If you are seeking a way to get real value out of SIEM data, consider co-sourcing that problem to a team that does that for a living. SIEM Simplified was created for just that purpose. Switch from TMI, TLA (Too Much Information, Too Little Analysis) to JEI, JEA (Just Enough Information, Just Enough Analysis).
