Error 404--Not Found

Error 404--Not Found

From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:

10.4.5 404 Not Found

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.

If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

Security Management

Security event, patch, policy and client management tools

Winning company: ArcSight
Winning product: ArcSight 2.5

Taking into account the ever-growing number of security devices you can put on your network, you'd be hard pressed to find enough hours in the day to even look at all the data regarding potential hacks these mechanisms are throwing your way.

That's exactly why we put security event management products on our testing roster last year and selected one of them as our winner in this category. Managing the alerts or logs on security events, such as blocked packets, failed logons or attempted exploits, is the next necessary step in the evolution of the corporate security infrastructure.

Based on our testing, the best product in the umbrella security management category was ArcSight's ArcSight 2.5 (see review).

In our December 2003 test of five security event managers, Lab Alliance member Mandy Andress gave ArcSight 2.5 accolades for its ease of use, facilitated by a slick user interface, and its overall flexibility in terms of the information it could collect and how it could parse and present that data.

The interface is surprisingly easy to use when you consider what you can do with it. You can configure your workspace with any number of graphs and views, all completely customizable. You also can drill down to more detailed information at just about every point, turning any data into a graph.


The company has not upgraded ArcSight 2.5 since its late October 2003 release.

Watch this space: The hot testing spots for us this year are the advancements in vulnerability assessment, patch management, security auditing and policy management technologies. We’ll test single products that offer unique approaches to these tasks throughout the year and plan a comparative review late in the year for products that offer a combination of these security management techniques. Additionally, we’ll test tools that specifically focus on helping network managers lock down distributed client machines.
