3M Privacy Filters Update

I have blogged about 3M's privacy filters before and their gold filter still remains, in my opinion, the best privacy filter on the market. If you want to find out more about that one and why you need a privacy filter, see my previous blog post "Why do I need a privacy filter? (3M's new Vikuiti Gold Privacy Filter)". I also blogged about their mobile phone privacy filter.

The problem with their mobile phone privacy filter last year was that it was only available in their standard grey louvered filter, so didn't work well with accelerometer phones that can be used in portrait or landscape modes - you had to pre-select which orientation you wanted to use your smartphone in. Also, the light transmission wasn't as good as the gold filter nor was the touch quite as good after applying it.

Well, they've addressed this and lanuched a new filter for mobile phones and slates at InfoSecurity Europe. The filter is now significantly thinner with excellent touch response and better light transmission - they also have a clarity measure which makes the screen easier to read with the filter (it does kind of work, having seen an iPad with only half the screen covered). They also have (in the lab) a grey louvered filter in two planes. This stops people from being able to read the screen if they aren't directly in front of it and deals with mobile phones and slate devices that can be used in the two orientations. This filter isn't available yet, but 3M told me that they were targeting the end of this year for these new filters. 3M also assured me that the new filter with double-louvers will be no thicker than the current one. This, combined with 3M's great adhesive that allows for a simple application, will make 3M's new privacy filters for mobile phones and slates the one to have, especially as they double as screen protectors.

Unfortunately they only do pre-cut versions for iPhones, iPads and HTC phones at the moment. If you don't have one of these then you will have to either cut it yourself or get a third party to cut one for you.

Coventry Building Society Grid Card

Coventry Building Society have recently introduced the Grid Card as a simple form of 2-factor authentication. It replaces memorable words in the login process. Now the idea is that you require something you know (i.e. your password) and something you have (i.e. the Grid Card) to log in - 2 things = 2 factors. For more about authentication see this post . How does it work? Very simply is the answer. During the log in process, you will be asked to enter the digits at 3 co-ordinates. For example: c3, d2 and j5 would mean that you enter 5, 6 and 3 (this is the example Coventry give). Is this better than a secret word? Yes, is the short answer. How many people will choose a memorable word that someone close to them could guess? Remember, that this isn't a password as such, it is expected to be a word and a word that means something to the user. The problem is that users cannot remember lots of passwords, so remembering two would be difficult. Also, having two passwords isn't real...

Trusteer or no trust 'ere...

...that is the question. Well, I've had more of a look into Trusteer's Rapport, and it seems that my fears were justified. There are many security professionals out there who are claiming that this is 'snake oil' - marketing hype for something that isn't possible. Trusteer's Rapport gives security 'guaranteed' even if your machine is infected with malware according to their marketing department. Now any security professional worth his salt will tell you that this is rubbish and you should run a mile from claims like this. Anyway, I will try to address a few questions I raised in my last post about this. Firstly, I was correct in my assumption that Rapport requires a list of the servers that you wish to communicate with; it contacts a secure DNS server, which has a list already in it. This is how it switches from a phishing site to the legitimate site silently in the background. I have yet to fully investigate the security of this DNS, however, as most...

Web Hosting Security Policy & Guidelines

I have seen so many websites hosted and developed insecurely that I have often thought I should write a guide of sorts for those wanting to commission a new website. Now I have have actually been asked to develop a web hosting security policy and a set of guidelines to give to project managers for dissemination to developers and hosting providers. So, I thought I would share some of my advice here. Before I do, though, I have to answer why we need this policy in the first place? There are many types of attack on websites, but these can be broadly categorised as follows: Denial of Service (DoS), Defacement and Data Breaches/Information Stealing. Data breaches and defacements hurt businesses' reputations and customer confidence as well as having direct financial impacts. But surely any hosting provider or solution developer will have these standards in place, yes? Well, in my experience the answer is no. It is true that they are mostly common sense and most providers will conform...
