VXE

VXE is an innovative software that offers protection to UNIX servers from potential intruders and hacker attacks coming from the network. It provides high-level security measures by safeguarding software subsystems, like SMTP, POP, HTTP, and other pre-existing ones on the server. One of the most significant challenges with UNIX security is that the superuser has full control over the system. Some programs, called daemons, work with superuser privileges, exposing them to network access, usually via the Internet or Intranet. Any programs are prone to bugs or vulnerabilities, and exploiting these security gaps could give intruders access to the server, allowing them to take over the system.

VXE, or Virtual eXecuting Environment, is an Intrusion Prevention System (IPS). It is designed to provide comprehensive protection to UNIX servers by safeguarding them and all subsystems from potential intruders and network attacks. With VXE, there is no need to reconfigure the existing system, and users can protect the software systems in place without any hassle.

VXE has various uses, such as providing daemon protection, allowing user access to the command line (shell, telnet) with restrictions, and hosting user CGI, among others. By using VXE, resources available to programs provided by a user can be limited, providing a convenient way to have user-uploaded CGI scripts. The software restricts users' access to specific files and tools, and these access limitations cannot be bypassed.

One notable feature of VXE is that its source code is available under the GPL license. Additionally, the latest release of VXE includes new functionalities, such as the use of vsnprintf instead of vsprintf in print.c, fixing common.vxf for two strings syscalls, printing arguments of system calls that caused LISP errors in logs, and using PERL instead of LISP and TclX in the web-based VXED development system.

In summary, VXE provides an efficient, effective solution to the critical security challenges faced by UNIX servers. With its robust security measures and user-friendly features, it is a reliable option for anyone looking for easy-to-use software that guarantees the safety of their UNIX servers.
