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.

Because it can circumvent many existing content-management solutions, instant messaging (IM) is causing security concerns among IT managers, which often leads them to ban its use altogether.
However, IM can have business benefits if used responsibly, because it offers instantaneous communication and immediately indicates whether colleagues are online. What is needed is a way of allowing the use of IM, while controlling it and enforcing rules on employees.

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.

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.

An interesting phishing scam has emerged that claims to be from an eBay user rather than the auction company itself.

PDAs are so portable as to make them susceptible to loss or theft - in a business environment the net result of this can range from inconvenience and embarrassment, right on up to serious problems with the regulatory authorities. Which is where SafeGuard PDA enters the frame. Like similar offerings from F-Secure and Pointsec, the software is designed to make a Pocket PC-based PDA as secure as electronically possible.

CyberAngel is actually one of several competing packages on the market in the U.S. and Canada that allows a central monitoring station to detect when an unauthorized access to a PC or notebook has taken place, and alerts the owner accordingly.

McAfee is well known for anti-virus software, and has built its complete anti-virus engine into an internet gateway product that examines HTTP, FTP, SMTP and POP3 traffic for viruses. It also performs content filtering and acts as an email anti-relay. Within the content filtering mechanism anti-spam functionality is included.

Messaging security and management firm MailKey is launching an authentication technology to fight spam, identity theft and prevent viruses.

GFI LANguard System Integrity Monitor (SIM) detects whether files have been changed on a Windows 2000/XP system. It identifies exactly which files have been changed, making it easy to restore the system to its original state, although it does not provide any utility for automatic recovery - you have to have secured original copies of these files elsewhere.

This inventory application uses a technology called Lanprobe to meter software usage and discover devices on a network.

The SmartFilter product from Secure Computing was one of the earliest products to perform category-based URL filtering. Now in version 3.2, the basic principles of the product remain, with performance and management improvements aimed at making the task of controlling web access as simple as possible.
SmartFilter is intended to sit on a web proxy behind a firewall, or on the firewall itself. The product comprises agents that reside on the gateways, a management server that runs on Windows, Solaris and Linux servers, and a management console which can run on the same platforms. The server and console components are both Java based.

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 solution provides a network-based IDS, real-time session monitoring and internet/email content blocking. eTrust Intrusion Detection can be installed in standalone mode, or it can be distributed on separate machines. The intrusion detection program installs as a service under Windows NT/2000. As usual, the monitoring interface is a NIC in promiscuous mode, and therefore the presence of the IDS is concealed from the attacker.

A trojan virus is doing the rounds hidden in an email message from Microsoft warning about the Zotob worm.

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.

This latest piece of software from Rockliffe is quite a change from the norm. MailSite MP (Message Protector) is a gateway product designed to sit in front of a mail server and filter spam, viruses and combat DOS attacks.

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.

Security has been the mainstay of SurfControl's business for quite some time, so it is no surprise to see an email security solution. A policy-based application, SurfControl E-mail Filter is actually an SMTP host through which all mail is diverted.

Installation is amazingly simple. It's just a matter of entering the required information into a few windows and telling the product where it sits in relation to the email server. For reasons of economy, it can be installed on the same machine as the mail server, but for reasons of reliability this isn't recommended.

This product complements the broader Web Filter software from the same company and borrows the basic engine from Akonix.
