Another policy enforcement product, but with some added features that really give it some teeth, is iomart's NetIntelligence. As well as monitoring URL requests, it also looks at the network as a whole (hardware, software and all files) and can instantly detect whether any unauthorized changes have been made, or whether any prohibited content is suddenly present.

N2H2 is generally considered to be one of the best content/URL filtering products on the market, and looking at in this group test, it is easy to see why.

NetIQ MailMarshal was the sleeper hit of the recent email security Group Test. Can this New Zealand-based software development center make it two in a row with its WebMarshal browser control? The answer is a resounding yes.

Unique in this test, the iPrism is actually an appliance. Although these tend to be more expensive than software-only products, they usually have the advantage of a fairly solid configuration since they are factory-build.

Recently acquired by NetIQ, VigilEnt Policy Center provides a policy management tool that ensures users are aware of their responsibilities while providing solid policy control across the company network.

This is a corporate-level security solution and requires a user database to allow you to import users so that user groups can be established. The policies can then be set for these groups, with users being required to answer questions to establish understanding and compliance. Logs are kept to view user input and also to define problem areas. This performance-related system means that users know how to use company data and they learn what is required of them, while the administrator can see statistics and reports. Users not complying can be identified and an email can be sent to them to remind them of its significance. This ensures that not only do your employees comply with your policies, but your company can prove compliance with the regulators and specifically with ISO 17799.

You can stipulate certain user rights to allow for policies to be reviewed prior to publication and distribution. But of course you may use pre-written policies, amend them or create your own, as required by your own particular corporate needs.

Each enterprise will look long and hard at how they implement their corporate security policy. While many administrators look to implement an enterprise-wide solution, some may look to deliver specific policy management features for areas that their particular enterprise rates as high risk.

This means that in order to deliver policy management across all electronic communication a specific policy solution will be required that specializes in this particular function.

We've looked at PoliVec Builder in the past, a policy development tool from the same stable. Part of the PoliVec suite, PoliVec Enforcer integrates seamlessly with its policy development tool counterpart to keep the enterprise secure.

Therefore, policy can be locked down to stop system changes and policy non-compliance from weakening the protected network infrastructure. Extensive reporting enables a precise picture of your network and real-time monitoring ensures that notification of problems can be dealt with in a timely fashion.

What strikes you when looking at the installation instructions for the securiQ and organiziQ Suites is the sheer number of operating systems supported. Although the mail server has to be Lotus Domino, alongside the familiar Windows platforms we see IBM OS/2 and AIX, Sun Solaris and a couple of Linuxes. We're told that from January the mail server will not have to be Lotus Notes, but our review was not able to verify this.

securiQ focuses on the management and security of email traffic, with features such as anti-virus available. This allows you to use your tool of choice, but does seem unfair given the cost. organiziQ manages the administration and overheads incurred by email.

No security software Group Test would be complete without an appearance by Symantec, and this is no exception. Symantec's offering is its Norton Internet Security Suite, specifically targeted at the standalone desktop machine, or those connected to smaller networks. Because of this, it is only available for non-server versions of Windows.

Installation of the product is extremely straight­ forward, aided by the very well-written documentation; as you would expect, considerable emphasis is placed on the prevention of viruses. The product very much urges you to take responsibility for your own actions, and the manual contains a very useful guide to the risks the internet can pose - something many home users may know nothing about.

Sometimes dialing into access data just isn't enough, and NetOp Remote Control allows remote access for the control of multiple PCs. This allows users to remotely initiate work from a distant location on their office workstation, enabling work to continue when they are unable to physically be at their desk. It can also provide useful and cost-efficient support from administration for problem solving, staff training and observation, or simply data use, all rolled into one.

NetOp Remote Control secures the communication while allowing authorized access. Controlling a keyboard and mouse, and viewing the screen of a remote computer is made easy with this solution, which makes an ideal tool for administration and management purposes wherever the skilled user is located. This means that a business can employ an expert at one location, but the enterprise can benefit from his or her expertise in branch offices no matter how diverse they may be ­ geographically.

Not all remote access initiatives are used solely to provide employees with multi-location access. It may be necessary to provide a wider core of access rights that are in line with your business activities and, therefore, a more extensive resource may be required to fulfill all of your objectives.

This is where a solution such as Novell iChain comes into its own. This solution accomplishes more than simply allowing one level of access. It is capable of delivering a web-based authentication process that can be granular to your business needs, allowing customers and partners to access areas crucial for your commercial needs.

We've looked at software solutions available for remote access, ideal for both corporate and employee use with many features, as well as being easy to install, configure and use. But what of the hardware alternatives to the problem? Do they also offer ease of use when accessing systems from geographically diverse sites?

Our next solution is a sleek and visually pleasing hardware alternative, which has been developed for the permanent off-site situation. This unit delivers a secure and robust communication between both sites without the remote user requiring new software or special training.

Hardware located in the main office on your LAN can allow remote workers punctual and user-specific access to work areas that need to remain secure during any remote communication periods. The ability to use this type of access improves productivity and ensures that employees are able to work remotely without compromising your network security.

Information security professionals are great at taking orders. Business leaders tell us what they want and we'll respond. We'll write rules and policies for use of email, the internet or remote access and we'll act as policemen when these rules are breached. But there's a real need for security professionals to step a little further outside this box. Most major federal agencies have not begun planning to transition to Internet Protocol Version 6 (IPv6), putting agency information and systems at risk, according to a report from the U.S. Government Accountability Office. In today’s ever increasing security conscious market, it is no longer sufficient simply to delegate the information security of an organization to the network administration staff. Providing remote access to business critical applications and information is no longer optional – it’s a ‘must have’ for today’s extended enterprise. Employees are more mobile, telecommuting continues to escalate, and partners play an increasingly important role in business processes. More so than ever before, companies require secure, anywhere access to internal applications, real-time information distribution and interactive collaboration. The University of Texas (UT) Health Science Center at Houston completed a network upgrade to protect and encrypt personally identifiable patient and employee financial information, electronic protected health information (EPHI) and intellectual property.

EnCase from Guidance Software has established itself as the leading tool for forensic investigators. Perceiving a need for similar tools in the enterprise space, the company announced EnCase Enterprise Edition, bringing most of the functionality enjoyed by criminal forensic investigators to corporate users.

Not all users want to resort to single user products to protect their SME business systems, and often the corporate editions are just not geared to the smaller business model. But McAfee Active Virus Defense Small Business Edition offers the level of security required for the SME market without compromising on any vital areas of virus protection. It delivers a suite of products that enables the SMEs amongst us to manage, update, and police our systems before any damage is done.
