VXE 1.57 Description:
VXE protects UNIX servers from such intruders, hacker attacks from network and so on. It protects software subsystems, such as: SMTP, POP, HTTP and any other subsystem, already installed on the server. Main problem with UNIX security is that superuser can do with system anything he wants. There are programs (daemons) which work with superuser privilegies, for example popd, sendmail, and accessible from network (Internet/Intranet). There could be bugs in any program, so intruder connects to such programs via network, exploit existing bugs in it and get a control over all host.
