IT security specialist ComGuard is to work with intrusion detection systems firm Enterasys to offer network intrusion detection solutions to businesses in the Middle East. The services shield companies from damage from cyber terrorism and internet hacking that results in financial loss of hundreds of millions of dollars.

Daniel Nufer, marketing director, ComGuard, says that a balanced and effective information security programme requires both preventive and detective controls. The benefit of new IDS technology is that it allows a network administrator to approach the issue of protecting the network in much the same way that one would protect the home against unwanted intruders.

Dr Amine Mehablia, head consultant at ComGuard, explains that a good home protection system alerts its owner that intrusion is being attempted or has taken place, and then notifies the police to attend to the issue.

“We watch for port scans to determine if an assailant is monitoring a network for vulnerabilities; we watch for remote password attacks to determine if an assailant is ‘rattling the doorknob’ to test if a network is properly protected; and we watch for application buffer overflows to hear the sound of ‘shattering glass’ that signals to us that an assailant has gained unlawful entry into a network.”

“Finally, we log all the evidence of the intrusion, so that when the case is addressed in a legal proceeding, the organisation that suffered the intrusion can seek financial compensation for damages,” concluded Mehablia.
