I was asked to comment yesterday on the story that emerged about the Google mail accounts that were compromised over the last few days, so I thought I'd put some of my answers down here. First off, Google wasn't compromised ; a set of phishing emails were sent out and a fake Gmail login set up to harvest login details. These were used to set up forwarding rules to copy mail to another account. Unfortunately, although a large number of people are aware of phishing and are (to a certain extent) vigilant, it only takes one person within the organisation to fall for the attack to compromise security. The scammers are becoming better at targeting people and making the initial phishing contact more believable to some people. Phishing is not just about email, although that is the most common avenue for the initial contact. Social media is also commonly used and we have seen the use of SEO to force phishing sites to the top of search engine rankings as well. User education is the o...

I have been tasked with rolling out a trial multi-factor authentication system that must be user-friendly, secure, low-cost and have zero impact on the existing network and users who won't be on the trial. That should be simple! A trawl round the InfoSecurity Europe show always helps, as you can get the latest state of play from all the major vendors. This year there were the obvious keyring tokens, SmartCards, USB tokens, SMS solutions and some innovative software solutions, including GrIDsure. Before making any decisions about the solution to go for, several things need to be decided, among which are: how much security is required? What is considered user-friendly to a normal, non-technical user? What metrics should we use for authentication? To answer these we need to look at what authentication is first: Authentication is the binding of an identity to a subject. The subjects we're talking about in this case are users and we're trying to bind their digital identity, ...

Well, a couple of weeks ago I went to InfoSecurity Europe 2009 at Earl's Court, as I do every year. If you've never been, but are at all interested in network and information security or are looking for vendors, then I highly recommend visiting. To my surprise, and for the first time I can remember, Microsoft wasn't there. Apart from that, however, all the usual players were there and, to be honest, it was all much the same as before. There was no new emerging technology or hot topic, just new developments of old technologies. A couple of years ago we had the hot topic of 'social engineering' and 'securing the user'; ok, we all knew that the users were our weak link and phrases like "we spend all our time securing the first 2000 miles and forget about the last 2 feet", and "our network would be totally secure, reliable and fully functional if we didn't let users login", have always been commonplace, but there were new mass threats, n...
