Commercial Linux distributor Novell last week continued to build out the security features of its SUSE Linux by acquiring e-Security, a provider of automated compliance and reporting software, for $72 million. e-Security, which is based in Vienna, Virginia, was founded in 1999 and its Sentinel security event manager software is used by 150 companies, many of them very large organizations who have had their IT operations turned upside down by various government compliance regulations in the past year. The Sentinel software collects, aggregates, correlates, and displays event information as it relates to users, resources, and applications. Sentinel 5 comes with a whole slew of what are called “collectors,” which is just another way to say monitoring agents. Collectors are created for the device, application, and network levels.
