InfoSecurity Europe is over for another year. Once again there were several interesting companies and sessions worth noting. The 'themes' (if they can be called that) or 'hot topics' were cloud security again, social media and mobile access/the consumerisation of IT. The big difference seemed to be in the attitudes of people - more 'how can we reduce the risks to an acceptable level?' rather than 'we can't secure it, so we won't allow it!' We are seeing a shift in the types of systems end users are accessing the corporate network from. The IT department are no longer dictating what will or will not be allowed. More and more users want to use their own personal devices, such as iPhones or iPads, on the network. In the past IT departments have resisted this and said no to the users. However, this attitude is beginning to change and there were a raft of organisations with solutions to help secure these devices and manage the data they contain. How...

Once again InfoSecurity Europe was an interesting place to visit. Lots of good sessions and interesting people to talk to. Most of the usual protagonists were there and the organisers have increased the educational part of the exhibition as well, which is good. I thought I would put down a few things that I thought were noteworthy from the exhibition. I've already blogged about the GrIDsure anti-phishing sender verification and the new 3M mobile phone privacy filters , but there were a few other things I want to mention. The first one is Panda Security's new Panda Cloud Internet Protection . This is a cloud-based service that provides consistent security and access policies to all machines within an organisation. The key thing is that it will protect mobile machines that are outside the corporate network with the same policies as those within the network. Protecting corporate machines when mobile is a big concern and a good way to reduce malware or hacking problems on the...

Data stored in the cloud can be compromised or lost (see my previous post ). So, we have to come up with a way to secure those files. We can encrypt them before storing them in the cloud, which sorts out the disclosure aspects. However, what if the data is lost due to some catastrophe befalling the cloud service provider? We could store it on more than one cloud service and encrypt it before we send it off. Each of them will have the same file. What if we use an insecure, easily guessable password to protect the file, or the same one to protect all files? I have often thought that secret sharing algorithms could be employed to good effect in these circumstances instead. What are secret sharing algorithms? They are algorithms that will share a secret between several parties, such that none of them can know the secret without the help of others. Either all or a subset of them will need to get together and put their parts together to obtain the original secret. A simplistic solution can...

Comodo Vision Video Blog Cloud Services or Cloud Computing are getting a lot of attention in IT circles, promising cost-effectiveness, flexibility, and time-to-market advantages over traditional alternatives. However, they also increase your security risk by expanding your security perimeter to include that of your service provider. This video blog poses some key questions to ask your Cloud services/Cloud Computing provider regarding data security as well as advice to reduce the risk to your business introduced by Cloud Computing. See my third video blog for Comodo Vision here .

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...
