A leading security vendor has welcomed the formation of an organization to represent the long-term needs of large corporations. Technology can only go so far in protecting company secrets. As Nick Booth discovers, people are the most vulnerable resource The security of an environment is often won or lost at the architecture level. My hype-meter has been jumping in recent weeks, illuminating a rocky road for the security market that will produce some corporate casualties in the near future. Imagine you work for one of those companies where information security is taken seriously, senior management support is for granted, the appropriate IT defenses are deployed and users are educated on the security policy. What is in essence a framework for designing, developing and building a new generation of applications around web standards and protocols, web services promises to make it far easier to integrate applications across disparate hardware and software platforms - a constant gripe with existing technology. Backed by all of the major IT vendors (Microsoft, IBM, Sun, Oracle, etc.), web services certainly will not suffer from a lack of effort or exposure, but will it take off and what are the issues? Denial-of-service (DoS) attacks just got worse - and easier! DoS is actually a grab bag of a great many techniques (such as worms and SYN flooding), all with the objective of denying legitimate clients access to services running on Internet based servers. Email-borne threats continue to evolve and have started to combine in new and dangerous ways. IT qualifications and security certifications are becoming more and more important to both individuals and companies alike, especially important in this current politically turbulent climate. For a business continuity plan to be truly effective at the time of interruption or disaster, everyone within the company needs to pull together to make the plan work and turn interruption into continuation.

One of the major headaches for network administrators is bandwidth consumption. However big your pipe into the internet happens to be, it's the last few feet from the server to the desktop that is the killer. A few years ago, people took their eye off the ball where bandwidth is concerned, as it was assumed that everyone would be migrating to the fatter cables of category 6. However, standards issues and an unwillingness to spend money in today's uncertain times means bandwidth is still at a premium. Files have not stopped growing, with multimedia data bringing many networks grinding to a halt.

Matters would be considerably worse if it weren't for the godsend that is PKZIP. Files are compressed by as much as 90 percent, allowing hefty files to shrink to more manageable and less bandwidth-hungry sizes. Probably the most ubiquitous non-Microsoft application around, PKWARE's PKZIP is probably the best compression program available - well, they did invent the Zip format.

When considering security in any area, be it IT, ATMs or even opening your own front door, there is always one weak spot: it has to involve people. Despite all the research, we are years away from being able to recognize a person's identity with 100 per cent certainty (even if using finger-printing, retinal scanning or DNA testing) in real time.
Unfortunately, the drive to encourage remote working means that more and more people need access to the corporate network, with all of the security risks that that entails: how can you be sure who the person is on the other end? One solution - or rather, preventative measure - is to simply publish only necessary information on an extranet, but even then, this can still be confidential data and a risky business.
