With the growth of Instant Messaging and peer-to-peer (P2P) technologies, businesses are increasingly facing security and management challenges. In January 2003, "Bank of America" was the most prominent victim of the aggressive "Slammer" computer virus that Richard Clarke, the former top adviser to President George W. Bush on cybersecurity, simply called "a dumb worm".

In last year's anti-virus management group test, Hauri's product impressed us with a slick interface and strong set of features. In this test, first impressions were similar. Configuration was quick and easy and the interface excellent - limited options compared to other products, but ample for most users. No reboot was required and the software demanded confirmation that the empty admin password required was in fact correct.

Known as Megabeam until late last year, Swisscom Eurospot is able to offer service at more than 1,100 venues.

Security experts have warned of a fast spreading adware file designed to tempt unwitting recipients with the promise of free music and videos.

Adhaero Doc is not a general-purpose encryption product, but it uses encryption technology to secure Microsoft Office files throughout their lifecycle. It also integrates with Microsoft Outlook to provide the same protection to emails. It is best described as a digital rights management product.

FileAssurity Open PGP is designed to be a low-cost alternative to PGP, while retaining full compatibility with PGP. With it, you can generate, import and export X.509 and PGP keys and it also supports encryption/decryption and digital signing/verifying of standard PGP files. Files or folders may be encrypted for storage or transmission by email. Bulk data encryption is carried out using 256-bit AES, with public-key-based Diffie-Hellman being used for session key exchange. RSA and DSS are used for digital signatures. Another feature is secure deletion according to U.S. government DOD 5220.22M. All 32-bit Windows platforms are supported.

RSA SureFile combines RSA's encryption technology alongside PKWARE's PKZIP to create an encryption product that also compresses files and folders to save space and bandwidth. Because encrypted files are generally fairly random looking, they are incompressible by hardware that may be part of a bandwidth-saving infrastructure. So, it is better to compress files before encryption, or optimize both processes within one product as RSA Security has done.

Now in version 11, pcAnywhere is one of the longest-running remote access applications for the PC. We can remember using an early DOS edition in the mid-to-late 1980s.

Since our last look at this product in June 2002, BT has completed roaming arrangements with several other networks and now has quite a healthy coverage of most major cities in the U.K.

The Cloud, a division of Inspired Broadcast Networks, is something of a low profile public Wi-Fi network, preferring to stay in the background as a wholesale wireless network operator.
When the service was launched earlier this year, the company offered access through two options, pay-as-you-use sessions from a variety of outlets, or through third parties, such as BT OpenZone, whose users can now roam seamlessly onto The Cloud's network.

One-factor authentication (user IDs and password) is still the most widely used method, primarily because it is simple, easy and there are no pieces of hardware to configure. But there are many applications where this is just not secure enough. In two-factor authentication, not only do users need to know a PIN but they also need to possess the correct token. This higher level of security, combined with the token's memory and cryptographic processing capabilities, makes it particularly attractive as a solution for many situations such as digitally signing documents and mails and authenticating the user remotely for access to corporate networks through VPNs.

Kaspersky Lab's Administration Kit is a free tool for business users who have purchased the company's workstation products.

Mail-Lock falls into a new category of email protection software, which the vendor calls email personal information containment, or EPIC for short. The software is claimed to allow users to carefully control what recipients of email can do with the messages and certain types of attachments. It does this using encryption technology to limit the functions within Outlook, as well as the length of time a message can be viewed by the recipient. The time control element is, as far as we can determine, the package's unique function within the POP-3/SMTP environment.
This version of Mail-Lock is designed to function as an add-in for Microsoft Outlook in all its desktop Windows variants, protecting the text of the email, as well as MS-Word, Excel and Powerpoint attachments. If an attachment from another application is attached and sent, Mail-Lock cannot control what happens to the attachment at the recipient's PC: it will simply open as normal. The company is developing versions for Outlook Express and Lotus Notes users, but no timescales for the updated releases have been made.

When employees of the city of Tallahassee asked for wireless access, finding a secure solution seemed almost impossible, says Curtis Franklin

This is one for the serious business with a need for high availability and disaster recovery in its overall plan. The capability not only to replicate files but also only the part that has changed, is just one of Double-Take's virtues.

Putting a firewall in the home office should be a natural thing to do. After all, you are not only protecting your user but also the data that they will be working on, and probably holding, on their machine. This security is just as important as the security in the main office, as liability on data and business-critical information could otherwise be breached with ease. This is where a small but powerful appliance from a developer with experience in both the enterprise and SOHO markets is going to come in very handy.

A new tool aims to help companies figure out the potential return on IT security spending.

Easy Recovery Lite is just one of Ontrack's solutions for recovering data. This solution does not repair lost or corrupt computer hardware settings, nor does it repair registry and configuration settings, but it does concentrate on data recovery. With an emergency boot disk to hand, even when you cannot access Windows, files can be extracted.

This next solution is ideal for publishers and media houses that rely on Macintosh computers for their production activities. Intego Personal Backup X allows the user to back up their critical files, clone volumes and synchronize files between two volumes.
