Today is the 10th anniversary of World IPv6 Launch. IPv6 has been around since the 1990s, but some organisations were hesitant about using it for their websites. So, World IPv6 Day (in June 2011) was an opportunity for these organisations to enable IPv6 for 24 hours. That way, if anything broke then it would probably …

Delete Exchange database
When you try to delete a mailbox database from Exchange, you might see an error like this: At first glance, that’s not very user-friendly! I’ve seen some people get stuck at this stage and ask for help. However, the error message does actually tell you everything you need to know.
CySA+ (CS0-001)
In March 2020, I took CompTIA’s CySA+ (Cybersecurity Analyst) exam. Along with PenTest+, this bridges the gap between Security+ and CASP. In simple terms, PenTest+ is about “red team” activities (attack) whereas CySA+ is about “blue team” activities (defence). This certification was launched in 2017 as CSA+, but it was rebranded in January 2018 because …
Palo Alto Networks Certified Cybersecurity Associate (PCCSA)
Palo Alto Networks make security products. In particular, they sell firewalls (physical and virtual), and their Panorama software will let you manage multiple firewalls centrally (e.g. for branch offices). Their certification program has 3 tiers: Entry level Administrator Engineer Palo Alto Networks offer free training for all of these, although you have to pay for …

CCNA R&S
Cisco have offered the CCNA (Cisco Certified Network Associate) since 1998, but it’s been through a few variations over the years. They’ve changed the syllabus and the number of exams: Year Part 1 Part 2 Combined 1998 CCNA (640-407) 2000 CCNA (640-507) 2002 CCNA (640-607) 2003 INTRO (640-821) ICND (640-811) CCNA (640-801) 2007 ICND1 (640-822) …
Offensive Security Wireless Professional (OSWP)
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 …

Microsoft 365 Fundamentals (MS-900)
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 …
PenTest+ (PT0-001)
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 …
SSCP
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 …
Security+ (SY0-401)
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, …
