The Security Zone With the mobility of employees and the ease with which external devices can be brought in and out of a network, continuing to build your security plan for network servers and clients is a must. Fortunately, there is much that organizations can do to protect themselves from attacks - internal and external. Having the right policies, procedures and server configurations is critical...

May 12, 2008 (Computerworld) Sometimes even the most protective phalanx of antivirus, antispyware and antiphishing programs is not enough to shield a computer from online dangers. Check Point Software's ZoneAlarm ForceField provides an extra defensive layer by cloning your Web browser to catch dangerous software before any damage can be done.

Rather than providing a magic bullet to stop online attacks by itself, ForceField augments traditional security software. While using ForceField, your browser looks and feels normal, but the program creates an encrypted virtual browsing zone that blocks malicious software at the first hint of an online threat. ForceField looks for malware signatures and a range of suspicious activities; it also uses heuristics to identify and block phishing. The software also can block dangerous downloads and spyware while keeping Web sites from recording your computer's keystrokes or screen images.

A test run

I downloaded and installed the 4.4MB program, which took about 5 minutes to set up. Unfortunately, the software only works with Windows XP and Vista computers that use Internet Explorer (Version 6 or newer) or Firefox 2.0. That means that it can't protect Macs or those PCs that use Opera or other Web browsers.

I tried ForceField with a variety of security software to see if it played well with others, and it had no problems with AVG Anti-Virus, Microsoft Defender, Symantec's Norton AntiVirus 2008 and Check Point's own ZoneAlarm Antivirus software.

The only visible element of ForceField is the toolbar it adds to your browser. (Unfortunately, ForceField doesn't integrate with Internet Explorer's toolbar, which would save some space). The toolbar features the ForceField logo and three icons: Protection Activity, Site Status, and Private Browser.

Clicking on the logo leads to a variety of settings for tuning the level of protection. Although ForceField duplicates what other programs do -- it has its own spyware-, phishing- and keystroke-logger -- I tend to prefer the belt-and-suspenders approach of extra protection. In other words, it doesn't hurt to have a bit of backup.

The Protection Activity button keeps tabs on items that the program has blocked. The Site Status button lets you see if the current site is potentially harmful and displays a quickie safety report.

Entering dangerous waters

I am generally a mild-mannered Web surfer who rarely strays off of the Internet's major sites. However, for this review, I threw caution to the wind and veered off the straight and narrow to visit some of the Web's dark alleys where troublesome software often lurks. When I then clicked on Protection Activity, the application reported that it stopped over 500MB of possibly harmful data, detected dozens of suspicious sites, and blocked eight phishing attacks and one virus. Not bad for four days of work.

As innovative as it is, ForceField has rough edges. It not only slows down the loading of many Web sites, but also caused IE to freeze up several times. The program may miss browsers opened by other applications, such as instant messaging programs; also, users of nProtect (a security application) and the SnagIt screen-capture app will need to disable ForceField's screen-grabbing protection to avoid conflicts.

Check Point has promised updates that will, I hope, fine-tune the program's balance between protection and irritation. Meanwhile, at $30, ForceField is an inexpensive online safety net for those who want an extra layer of protection.
