I often get asked what I look for when hiring security professionals and my answer is usually that I want the right attitude first and foremost - knowledge is easy to gain and those that just collect pieces of paper should maybe think about gaining experience rather than yet more acronyms. However, it's difficult to get someone to change their mindset, so the right attitude is very important. But what is the right attitude? Firstly, security professionals differ from developers and IT engineers in their outlook and approach, so shouldn't be lumped in with them, in my opinion. The mindset of a security professional is constantly thinking about what could go wrong (something that tends to spill over into my personal life as well, much to the annoyance of my wife). Contrast this with the mindset of a developer who is being measured on their delivery of new features. Most developers, or IT engineers, are looking at whether what they have delivered satisfies the requirements fr...

Over the last few weeks I have had many conversations and even attended presentations where people talk about 'Security Best Practices' and how we should all follow them. However, 'Best Practice' is just another way of saying 'What everyone else does!' OK, so if everyone else does it and it's the right thing to do, you should be able to prove it. The trouble is that nobody ever measures best practice - why would you? If everyone's doing it, it must be right. Well, I don't agree with this sentiment. Don't get me wrong, many of the so-called best practices are good for most organisations, but blindly following them without thought for your specific business could cause as many problems as you solve. I see best practice like buying an off-the-peg suit - it will fit most people acceptably well if they are a fairly 'normal' size and shape. However, it will never fit as well as a tailored suit and isn't an option for those of us who are o...

I was asked to sit on a panel of experts, gaze into the crystal ball and make my predictions for what 2017 holds in store for cyber security, which got me thinking. Let's start with more breaches, more ransomware, more cyber security jobs, wage increases for security professionals, more 'qualified' professionals who don't really know what they're doing but have a piece of paper and, of course, vendors making even more money out of Fear, Uncertainty and Doubt (FUD). However, none of those is terribly interesting or any different from 2016, or 2015 for that matter, or indeed anything other than trends in the industry. So what does 2017 hold in store for us in the security industry and is there anything new to worry about? Well an obvious one to call out is the EU's General Data Protection Regulation (GDPR). So what is GDPR? Well, GDPR replaces the previous data protection directive and aims to improve and harmonize data protections for EU citizens. This will i...

I was invited along to SC Media's roundtable on The Threat Landscape last week and they have written an article on it. I was also interviewed and appear in their video summary. The article and video can be found here:  https://www.scmagazineuk.com/roundtable-the-threat-landscape/article/635652/

Well, okay, it won't actually tell you whether they are secure or not and there are other questions you could ask, but the point is you can tell a lot about a company's security by how they answer security questions. I was recently at a security round table and the conversation turned to third parties and how you can assure yourself of their security. Some advocated scoring companies or certifications, while others advocated sending questionnaires. The argument against questionnaires is that they are a point in time view of the organisation. However, you can ask process and policy based questions and you can tell a lot from how they answer. So, what is the question that will reveal all? Well, as I said it's not one question as such, more a type of question. It should be about something basic, some security control you're sure they have because everyone does. For example: Why do you have a firewall? Probable answers: "because everyone has one"/"bec...

When is a deleted file actually removed from your device, or at least when does it become unrecoverable? It turns out that this question isn't always easy to answer, nor is a secure file deletion easy to achieve in all circumstances. To better understand this we have to start from the basic principle that when you delete a file on your computer you are only deleting the pointer to the file, not the actual data. The data on your hard disk drive (HDD) is stored magnetically in sectors on platters that spin round inside the HDD (we'll come onto SSDs in a bit). So, how does the computer know where to look for your file? It has a table of indexes such as the File Allocation Table (FAT) or Master File Table (MFT) in NTFS. When you delete a file in your OS, all you are actually doing is removing its entries from the table of indexes so your OS can't find it any more and doesn't know it's there. However, all the data is still stored on the disk and IS STILL RECOVERABLE! T...

Security professionals can't afford to work in isolated bubbles when the attackers are openly sharing information about system vulnerabilities... Watch my video interview for SCMagazine here .
