The explosion of spamming, hoaxes and cyber attacks has highlighted just how vulnerable users are to security breaches and the steps they need to take to protect themselves. While both dial-up and broadband connections can be affected by such security breaches, an always-on broadband connection is undoubtedly an easier target. This is because the always-on nature of a broadband connection means that attacks and hacking can happen around the clock, raising the stakes by comparison with a computer that is only on for short periods. Luckily, there are many tools available to make broadband connections secure and attractive to users and potential users.
Three years ago, I proposed to our technology architects that we eliminate our network firewalls. Today, we're close to achieving that goal. Back then, I thought that network-based firewalls were losing their effectiveness, enabling a mind-set that was flawed. Today, I'm certain.
I maintain a bunch of servers at our labs in the university. Of late, the number of attacks on the computers has been more noticeable. The university provides firewall software (Kerio) but that doesn't work with Win 2003. And so we keep getting hit by zombie machines taken over in the Education Department or from Liberal Arts. So what does the Slashdot crowd use when they need to secure their Linux and Windows servers? Does it cost less than US $100?
Endian Firewall is a turn-key Linux security distribution based on IPCop that turns a system into a security appliance. The features include a stateful packet inspection firewall, application-level proxies for various protocols (HTTP, POP3, SMTP) with anti-virus support, virus and spam filtering for E-mail traffic (POP and SMTP), content filtering of Web traffic and VPN (based on OpenVPN).
If you want to set up a Linux-based firewall, there's no need to run a bloated distribution that installs everything but the kitchen sink. If you are not afraid to get your hands dirty, and like having total control over your system, then Sentry Firewall CD (SFCD) is just what you need. It is a highly configurable, bootable CD that takes a minimalist approach to firewalling.
