In April 2019, I took the Offensive Security Wireless Attacks (WiFu) course and the OSWP exam. (Along with PenTest+ and Microsoft 365 Fundamentials, this was my third exam in a month!) In brief, I enjoyed this. I thought the content was interesting, and the exam was actually fun (similar to an escape room). However, the …

In April 2019, I took the Microsoft 365 Fundamentals (MS-900) exam. Microsoft offer free training; they say that this will take 4 hours 11 minutes, although you might find that you need to repeat some of the videos if you didn’t fully understand it the first time through (e.g. if you got distracted). It would …
In April 2019, I took CompTIA’s PenTest+ exam. Along with CySA+, this bridges the gap between Security+ and CASP. As the name suggests, it’s all about penetration testing. This is a relatively new exam, and it’s still on the first release (PT0-001). Because of that, it’s not very well known, so I haven’t seen any …
In September 2018, I took the (ISC)2 SSCP exam (Systems Security Certified Practitioner). This was a bit different from any of the previous exams I’ve taken: normally I would sit the exam(s), then get a qualification if I passed. In this case, the exam is only one component: you also need to be endorsed by …
In November 2016, I took CompTIA’s Security+ exam. NB I did the SY0-401 syllabus; CompTIA replaced it with SY0-501 in October 2017, so some of the info in this blog post will now be a bit out of date. In brief, I think that this is a worthwhile certification. It emphasises breadth rather than depth, …
For the last couple of years (since July 2018), I’ve been receiving “sextortion” emails. There a few variations, but the basic gist is always the same: “I’ve hacked your webcam and filmed you masturbating, now pay me money or I’ll send the video to everyone you know.” They often include my password, in an attempt …
A lot of organisations set up security policies so that users will be locked out if they enter the wrong password too many times. The idea is to prevent brute force attacks, where an attacker could sit there all day running through the dictionary until they guess the correct password. The downside is that this …
I’ve recently had a few conversations with recruitment agencies, where they’ve asked me to rate my IT skills from 1-5. However, I’m reluctant to answer, because I think the concept is flawed.
I recently earned the ITIL Foundation Certificate in IT Service Management, after about a week of study. I’m currently job hunting, and I’ve noticed that a lot of adverts list this as essential. It won’t get you a job on its own, but not having the qualification might exclude you from certain jobs, if the …
When you set up a wired network using Ethernet cables (e.g. Cat5e or Cat6), there are 2 types: solid and stranded. The rule of thumb is that you use solid cables when they’re not going to move, e.g. between a wall socket and a patch panel. You use stranded cables when they will move, e.g. …
