IT computer security is something that is very important for business owners. CIO.com has published an article that deals with the equipment that helps with the computer maintenance.
Security information and event management (SIEM) equipment is valuable for getting a bird’s-eye view of security in the enterprise, but there are deployment challenges that IT security managers need to recognize.
Reed Smith LLP, a large law firm that operates four data centers and about two dozen offices worldwide, has been progressing through an enterprisewide deployment of HP’s SIEM product, ArcSight. It consolidates and correlates input from firewalls, intrusion-prevention systems, servers, antivirus, vulnerability scanners, routers and more, including capturing NetFlow data. The firm is getting a better real-time picture of network activity, not just threats but server availability, for instance.
However, like exercising to get stronger, SIEM has some “no pain, no gain” aspects. Work has to go into properly activating a SIEM, according to Eric Mazurak, network and security engineer at Reed Smith.
“There will be a high false positive rate if you don’t do fine tuning,” says Mazurak, adding, “the more logging you do, the more tuning is involved.” Basically, that involves getting a thorough understanding of the SIEM interface and making changes to out-of-the box rules so that the SIEM is making the most accurate assessment it can. Mazurka recommends test-driving a SIEM for a while in a production network before committing to a purchase. Once the SIEM is in, it will need continuing maintenance, he adds.
