Sentry Firewall CD-ROM is a Linux-based bootable CD-ROM that functions as a cost-effective and low-maintenance Firewall or IDS.
The Sentry Firewall CD-ROM is a must-have software for businesses that are looking for an inexpensive and easy-to-maintain firewall, server or Intrusion Detection System(IDS) node. This Linux-based bootable CD-ROM is specifically designed to be immediately configurable for various operating environments. This can be done via a configuration file that is located on a floppy disk, a local hard drive, and/or a network via HTTP(S), FTP, SFTP, or SCP.
Booting from the CD-ROM is a straightforward process where the BIOS execs the bootloader(Syslinux) thereby displaying a bootprompt and loading the kernel and ramdisk into memory. Once the kernel is running, the ramdisk is then mounted as root(/). At this point, the configuration scripts (written in perl) kick-in and configure the rest of the system. These scripts are responsible for placing various startup and system files into their proper locations using either what is declared in the configuration file (sentry.conf) or the system defaults located in the /etc/default directory.
Most of the critical files used at boot time can be customized with your copy, as declared in the configuration file. This particular feature allows users to configure the system using their configuration and init files. Moreover, all of the binaries, files, scripts, etc, that have been used to create the CD-ROM are also readily available on the CD-ROM. With a little practice, users can easily build and customise their Sentry Firewall CD.
Some of the key features of this software include being based on a current 2.4.x series kernel, OpenWall security patch(-ow1), strongSwan, ebtables bridge+netfilter patch, Linux-WLAN modules, MPPE patch, modules-off patch, iptables v1.2.11, ebtables v2.0.6, OpenVPN, IProute2 utilities, Vconfig, PPTP client/server, Zebra, Snort IDS v2.2.0, Scanlogd, OpenSSH and OpenSSL, net-snmp, Webmin, NMap and many other daemons and binaries that users may need. Apache, Sendmail, Squid, Perl, BIND (static/chroot), and more can also be found within the software.
Overall, the Sentry Firewall CD-ROM is a fantastic tool for businesses that are looking to protect and monitor their network in a cost-effective way. Its features will undoubtedly provide the necessary flexibility to cater to most business environments.
