“The economic recovery has yet to make its presence felt at many
IT departments. Even within tight budget constraints, savvy admins
are able to layer their defenses by turning to open source and
freeware utilities that offer much of the same functionality as
full-blown suites from big vendors.“Cost benefits aside, such software is a relatively risk-free
way of experimenting with various setups, enabling administrators
and all those with an interest in network security to customize
their defenses without racking up the bills.“Naturally, there is a catch. Many of the tools don’t sport
fancy GUIs and customer support is oftentimes nonexistent. However,
any PC enthusiast worth his/her salt knows how to resolve problems
that may crop up (web searches, dedicated forums,
newsgroups…)”
