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.

Similar to LapLink, pcAnywhere has long been a serious contender for employees and employers requiring remote access to data. It also provides a very easy to use software system, but without the cables for synchronization of PCs that LapLink provides. What you get is a CD that installs with ease and a quality user's guide. pcAnywhere also provides the administrator with a rebootless host to allow for installation without the usual reboot ­ - great for servers that are critical to your business and require a problem to be assessed and ­ resolved remotely.

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.

So far we have tested conventional remote access solutions, but the next product is designed for remote access with a difference. Take a situation where you have servers in many different geographical locations, but where employing IT specialists around the world is not economically viable.

American Megatrends, Inc. recognized this problem and introduced a hardware solution that enables the remote access required to repair and develop new installations and configurations from afar. The MegaRAC G2 provides a speedy connection, enabling one employee to oversee all your IT needs from just one location - in an instant.

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.

It is not always a software solution that saves the day when you want to work remotely. From a small branch office or home office a VPN tunnel may fit the bill and SonicWALL has several hardware solutions that may provide the security that you are in need of. We took a look at the SonicWALL TELE3 SP as an alternative solution for secure remote access communications.

From a user perspective it is easy enough to install, and anyone who has purchased a PC and set it up at home for themselves will be able to get to grips with this small but secure solution. The TELE3 SP takes up very little room and is ideal for those using an always-on broadband connection. Alternatively, it comes with a fail-over modem connection, which can be set as default for non-broadband users.

One very important area of email security is encryption. Unless you are using leased lines or virtual private networks (VPNs) to transmit information, the moment an email leaves your firewall it is at the mercy of the internet. Emails can be intercepted and read without your even knowing about it, which poses a terrible risk for corporate information. However, encrypting the email does give you a high degree of ­ reassurance.

PC Guardian provides a nifty little program called Encryption Plus Email that allows you to encrypt email body text and any attachments. The email product is very easy to install - full installation of the administration program takes less than a minute. The product is designed for individual use, so the administrator installs it on each workstation, then configures it centrally and rolls out the user files across the network. Encryption Plus Email is only available for Lotus Notes and Microsoft Outlook, but since these two cover a large proportion of companies this shouldn't be a problem.

Administrators often forget that management of emails isn't simply a question of who can send or receive them, or the content. When email arrives it sits in the inbox, but who has permission to access that inbox, or other folders for that matter?

With high turnovers of employees becoming increasingly common, the stressed administrator may well lose track of individual permissions. For example, many companies usually have a set of freelance or contract email ­ accounts that can be assigned to temporary staff. The permissions required by one contractor may be far more extensive than those required by their successor, but they could very well inherit those permissions when they arrive. And human nature being what it is, inquiring minds will almost certainly take advantage of this, whether innocently or maliciously.

Although F-Secure may not be the first name in anti-virus that springs to mind, its products are among the heaviest hitters in the industry. Unlike some products which depend purely on their signature lists to be updated, F-Secure also comprises multiple scanning engines and heuristic detection techniques that make it one of the first products to detect new viruses. The company has now brought its expertise to bear in email security with F-Secure Anti-Virus for Internet Mail.

The product is available for Windows (NT and 2000). A Unix version would be nice, although there is a version for Unix which sits at the firewall level. Installation presented no headaches. However because of the way the product works, disk and memory requirements are quite high. It is also better to share the scanning across more than one scanner server to keep bandwidth usage lower.

Gordano is a company that has made the messaging arena its own. Its NTMail product was a revolution when it was first launched in 1994, and it was recently re-branded and overhauled to become Gordano Messaging Suite (GMS).

Installation is simple and straightforward, and Gordano has also ensured that the product is suitable for all major operating ­ systems. Once installed, navigation is easy: the product is logically structured with well-laid out GUIs. Both configuration and management are carried out via a web-based interface.

CyberGuard offers a range of firewall/VPN appliances with specifications ranging from three Ethernet interfaces and 125Mbits/ sec throughput to 21 Ethernet interfaces and 2Gbits/sec throughput. All have an integrated VPN, run the same firewall software, and have the same configuration GUI. We tested model KS1500, which can have up to 18 Ethernet interfaces, of which two are gigabit-over-copper as standard.
Performance is the strength of the KS1500, which is designed to cope with 1.5 Gbits/sec throughput and up to 1.2 million simultaneous connections. The firewall boasts a host of certification standards including Common Criteria Eval­ uation Assurance Level 4+ (EAL4+), ICSA, ITSEC E3, Checkmark, etc. The secure operating system was designed to meet TCSEC/NCSC criteria at the 'Orange-book' B2 level.

ViraLock takes a different approach to securing a users' email system from the ravages of viruses and other malware. Rather than prevent a virus infection, the software is designed to work with existing anti-virus applications and firewall systems to prevent a users' mailbox from being compromised by an executable of any type.

One potential security loophole that is frequently overlooked is access to removable media. Many access control products will bar your way into the file server, log your attempts to look at the payroll database, and prevent you from using certain applications, but this is all at the system level.

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.

If you think Unix houses have been ignored in this test, Symark's PowerBroker is just for you. Supporting multiple flavors of Linux and Unix - including IBM S390 Linux - PowerBroker ensures Unix administrative privileges can be safely managed and delegated.

This solution is probably more suited to the smaller business model as it requires separate installation at every workstation, unless you utilize the separate deployment console BitDefender Enterprise. This allows the installation, scanning, uninstall or the change of settings on all machines in the network. It can also be deployed across the larger network using wireless application protocol (WAP).

Most vendors deliver a variety of packages for different needs, but F-Secure puts one solution into a host of business models. Whether you are looking for a single user license, SME or enterprise, F-Secure AntiVirus version 5 delivers the whole shooting match.

For the larger SME that requires server protection which also covers workstations throughout an organization, eTrust AntiVirus can be called upon.

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.
