Debian Software

In spite of the rampant news of Internet fraud and scams, there are still a lot of web surfers who are still not mindful if the Online stores and websites where they shop are actually secured and running behind the best firewall software or not. Sometimes security also lies with how famous and widely used a software firewall is among the server administrators. One concrete example is the Debian firewall.

Debian is backed up by a large community of developers all around the world. It is used as the base for the famous open source platform called Ubuntu. A software developer would love Debian mainly because he would have the ability to study the codes and used them to integrate with other free software. Plus Debian also includes tools which he can use for proprietary applications. Likewise, configuring a Debian firewall , using IPtables commands is used on this platform.

Just like other best firewall software, a Debian administrator can set it to restrict or allow services such as inetd (telnet, ftp, finger, pop3), HTTP, SMTP. It can be set to allow access to trusted users, hosts or networks defining an Access Control List. It can analyze log files. It can secure a server’s mailing services and mailboxes such as POP3 and IMAP. Debian can also, secure domain server daemon in many ways. It can also manipulate the DNS server by restricting the information served to outside clients so it would not allow confidential information to leak from your network. Apache another open source web server runs in Debian. Through Debian firewall, the administrator can permit or disable to publish web contents securely. Debian also provide some software that can help set up chroot environment, in short if  a user or a service is dubious, the administrator can create a modified root environment for him. Firewall rules can be used to secure the access to the local system and limits its outbound communications. It can also be used to control processes that cannot be configured properly and restricts services to some networks, IP addresses, etc.

Finally, with Debian and all its flexibility to adjust with the common hardware and open source software, it may just be among the best firewall software for web servers, networks and a lot of organizations out there.
