Why is my spam in colour?
Today one out of four emails on the internet is an image spam message. This is not because spammers have just realised the marketing benefits of captive colours. Instead, this is because the spammers have identified a weakness in many anti-spam systems and are moving diligently to maximise this opportunity by fully exploiting this weakness.

Why is your network firewall falling short?
Your network is secure, your servers are safe, and you’ve done everything to protect your network, corporate assets and intellectual property. You have a network firewall, so your perimeter is secure. Your network devices and servers are only accessible through your corporate VPN via two-factor authentication, and all external ports are blocked to non-authenticated traffic.

Why IPS won't break your network
Back in 2003 Gartner declared Intrusion Detection Systems (IDS) as dead. Whether this is true, it is an increasing reality that intrusion protection or prevention systems are increasingly becoming a part of many company's networks. While IDS may be waning, IPS (Intrusion Protection Systems) are on the up, yet there is still a pervasive feeling that such technology can cause a network to break or malfunction.

Why good business is also good security
February is a big month for SC Magazine this year. We'll be having our SC Magazine Awards ceremony and dinner for the first time in the U.S. on February 16 during the RSA Conference at San Francisco's Moscone Center. It is, by far, the biggest and swankiest event by which excellence in all things IT
security is acknowledged.

Why should anti-virus products employ heuristic detection?
Once upon a time, in a galaxy not so far away, there were only a few computer viruses. Little more than a curiosity to most, they were relatively rare, slow spreading and in general, more of a mythological threat than a real one. The initial anti-virus products that were created to deal with these were perfectly adequate; updated once a month or so, the customers could be fairly sure that they would be protected. Fast-forward to today’s interconnected and always-on world, and the scale of the problem is orders of magnitude above where it was back in those early days.
