ZyXEL's ZyWall 35 shows that, while small in dimensions, it is not small on features. The front panel of the appliance houses two WAN and four LAN Fast Ethernet ports, while the rear of the device has out-of-band management through it is console port and a PC Card slot, so you can add 802.11g WiFi (see company website for supported cards).

Symantec's Enterprise Firewall works with Windows 2000/2003 or Solaris 8/9. We installed it on our Windows Server 2003 machine with two network interfaces (a requirement of the software).

Guardware produces a variety of innovative products, all of which have been well received. It was interesting, therefore, to see a keyboard product with integral fingerprint reader from this Hungarian company (although the keyboard is actually made in China).

This appliance hails from a Swedish company that has been going since 1997. The software runs on a Sun Netra X1 box (1U in size). It also has the widest range of client types we saw in this test.

TOS stands for 'trusted operating system.' It can also be used to protect servers that are providing DNS, as well as file servers, database servers, proxy servers and mail servers. TOS can protect any static files, including whole directories, drives, Windows registries and, of course, web pages.

WebAgain detects unauthorized changes made to web sites and can automatically restore altered web pages. It works with all popular web publishing software.

The software we received for this test was a pre-release of version 8, but initial observations tell us that any tweaks before the final version will probably be very minor ones.

Symantec's Gateway Security 5440 fits in the middle of its 5400 series range. It comes with six Gigabit Ethernet interfaces, although you can also buy the 5441, with four fiber and two copper interfaces instead.

The Nokia-Check Point partnership has been a successful one, combining Nokia's excellent hardware implementation with Check Point's proven security technology, as we can see with the IP380. Aimed at the small enterprise or branch office, the IP380 comes with a cryptographic accelerator, capable of 130Mbps of 3DES VPN traffic and four Fast Ethernet ports. With two spare slots in the 1U chassis, you can upgrade network capability at a later date.

Top Layer Networks' Attack Mitigator lies at the traditional end of intrusion prevention. It aims to defend against both internal and external hackers using denial-of- service (DoS) and distributed denial-of-service (DDoS), as well as giving broad protection against other well-known attacks. This is done using a mixture of stateful inspection hardware and packet inspection software.

Most of the products tested in the round up for this Group Test have been primarily aimed at the larger enterprise, as they tend to have the largest pockets and more need for protection. Barbedwire Technologies aims at the more modest-sized organization with its STAR Engine intrusion prevention product.

The main idea behind this piece of technology is controlling who or what makes calls to the operating system kernel. This protects file and registry from attackers and is particularly effective when software patches are unavailable.

The Aladdin eSafe Appliance is a hardened, Linux-based device, which can be configured as an email inspection tool (SMTP relay) and, additionally, as a full content-filtering gateway for HTTP/FTP. To obtain the full content-filtering gateway functionality you need to use Check Point Firewall-1 configured with a HTTP/FTP security server as a content vectoring protocol (CVP) client.

This is an enterprise recovery solution that provides centralized control for a fast backup and restore that is controlled by the administrator. Recovery Manager provides a system that also allows a full restore for any computer that has been unable to reboot. It does this by storing all registry and system files for each protected workstation, allowing a full recovery on any machine covered by Recovery Manager.

The principle of Xiscan is a good one. It takes the idea of war dialing software, which hackers have used to their advantage for many years to scan telephone networks in an attempt to locate entry points, and turns it against the enemy.
Xiscan works in the same way that the hackers have always used automated telephone dialers – to probe for weaknesses in the network. The difference is that it is designed to be used within the network, to locate rogue modems and bring users to heel.
The basic idea is that if hackers can use automated dialers to gain an advantage over legitimate users, then why can't the legitimate user do the same? It is a very good question – and there is something very satisfying about the idea of wrestling control of hacker-type tools, and using them for legitimate ends. Xiscan takes the wardialer idea and turns it on its head, using it as a way to monitor the network from within.

If anyone was under the illusion that data storage was boring, think again. The new technology engaged in protecting your critical data takes a fresh and enthusiastic approach to data security - ensuring that what you deem sensitive, value or trusted, is also worthy of iron clad protection within your storage infrastructure.
If you think that there's anything exciting to see as the data passes through the box, you'd be disappointed. In fact try finding CryptoStor within the Fibre Channel (FC) network or backup application and you may just hit a small snag - it's nowhere to be seen. But that's the point.

When considering security in any area, be it IT, ATMs or even opening your own front door, there is always one weak spot: it has to involve people. Despite all the research, we are years away from being able to recognize a person's identity with 100 per cent certainty (even if using finger-printing, retinal scanning or DNA testing) in real time.
Unfortunately, the drive to encourage remote working means that more and more people need access to the corporate network, with all of the security risks that that entails: how can you be sure who the person is on the other end? One solution - or rather, preventative measure - is to simply publish only necessary information on an extranet, but even then, this can still be confidential data and a risky business.

Remember the halcyon days of the dot-com boom, when analysts were insisting that no company worth its salt could continue in business unless they had a web presence? Their weighted words were sufficiently terrifying to ensure that businesses rushed to add that all-important 'e' to their trading, resulting in countless new web sites appearing.

Hackers have hit a Colorado university’s servers for the third time in under two months.
