If you want to leave certain nice to do's or ease of use functionality available to your self such as leaving SSH open only to root or having a machine with anonymous FTP access available, then take a slightly different approach to securing your environment (or those particular machines): layered security. Without changing the physical layout of your network, change the network layout using iptables and/or tcp wrappers. . This is essentially saying that all traffic that you want to funnel to Server II or Server III will now go through server I. This can be used in a variety of ways.

For enterprises today, the network is where business takes place. Every department in an organization relies on the network for applications and for a growing share of communications, not only e-mail and instant messaging, but soon telephony as well. The mission of network security is to ensure that applications can do their jobs and that applications have the network bandwidth and the availability needed to support the operations of the company. There's also a broader perspective on network requirements. It's a holistic view that encompasses security as well as availability, bandwidth and control. We call it network integrity. This is the real goal behind securing a network. When the network is functioning properly, providing applications with the bandwidth and availability they need, then the network has integrity, and security is doing its job, even when the network is under attack.

Should there be two security guards, one to spot potential intruders to your house and another one to stop him from getting in? If you transpose this to the enterprise-network situation, we are faced with a classic debate challenging CIO's and security experts alike. To elaborate on the parallel, consider a house with state-of-the-art security systems including laser fencing, burglar alarms as well as the guard at the gate. Compare this to your network where the house symbolizes the network, the guard is the firewall, the fence is the intrusion-detection system and the burglar alarm is the anti-virus software. However, the fact is that a lot of times, these measures even when put in place, fail to prevent an attack. The link for this article located at VoicenData is no longer available. .

We all know that two-thirds of corporate hacks come from inside the firewall, making internal security as important as external. But what about your remote offices and SOHO workers? Are they as vulnerable to attacks as your corporate workers?. . .. We all know that two-thirds of corporate hacks come from inside the firewall, making internal security as important as external. But what about your remote offices and SOHO workers? Are they as vulnerable to attacks as your corporate workers? Why layered? Nearly two-thirds of all security breaches are caused by insiders accessing unauthorized information - something a corporate firewall can't stop. Most security experts believe layered security is the way to go, as it's only a matter of time before someone finds their way through any single layer. Furthermore, a good layered security system not only protects your key network access points, but also protects them against different avenues of attack, known as vectors, including insider attacks.
