How To Prepare For a Security Information and Event Management Deployment
by Jason Holloway - ExaProtect, 14 May 2007.
SIEM should help you to free up the small, specialist security team from doing day-to-day investigations and device support work. It should enable you to meet compliance requirements for reporting, without large amounts of custom coding and scripting. And critically, it should cut the chances of a breach passing unnoticed, and shorten the clean-up period, reducing overall exposure to risk.

Remember, the ultimate SIEM goal is to help your existing teams to do more, be more reactive with their current resources and to enhance security. Now thatís well worth a little extra preparation.

Perfect SIEM Preparation: the crib sheet
  • Establish a cross-department steering committee first, to ensure all parties are onside
  • Build a security baseline: assess activities & risks, prioritise them, and how youíll remediate
  • Simplify the network before installing large management systems to shorten implementation time, reduce event numbers and raise input quality for SIEM
  • Boost signal to noise ratios for reduced hardware load and fewer events
  • Phase the roll-out
  • People and procedures are vital for successful deployment.
