Introduction
CCSK vs CCSP–I’m commonly asked two questions whenever someone discovers I’m an instructor for both the Cloud Security Alliance CCSK and (ISC)2 CCSP courses:
1 – “What’s the difference between the two certifications?”
2 – “How hard is the CCSK exam?” … It’s very hard, but more on that later!
In this entry I’ll identify the differences between two of the industry’s highest regarded cloud security certifications, CCSK and CCSP. Hopefully after reading you’ll know which certification will better fit your professional goals. I don’t believe I have a bias here because I’ve been teaching both courses for a while. In fact, I delivered the first public CCSK course outside of the initial Train-the-Trainer in San Jose. As for the CCSP, I actually helped develop that course. I believe what follows is an honest opinion between the two courses.
CCSK| Certificate of Cloud Security Knowledge (Updated for v4 Course)
Update for CCSK Version 4
The best way to describe the updates for CCSK V4 are that from a strategic 20,000-foot view it’s mostly more of the same. Governance, contracts, risk management, legal aspects are covered to mostly the same degree but they expanded it to be more global in nature.
However, drop down the viewpoint to that of a more tactical 1,000-foot view and the updated version is very different. Example: leveraging Lambda serverless computing and object storage to remove network attack paths back to the datacenter isn’t exactly a governance item; but from a more tactical approach, it really shows the different architecture patterns you can leverage in cloud that are basically impossible in traditional computing. They also pull in discussions that didn’t exist before such as containers, CI/CD toolchains, DevOps, Chaos engineering and expanded discussions surrounding Software Defined Networking security concepts.
CCSK Course Details
For the CCSK course itself, it’s delivered in two different formats:
- CCSK Foundation (1 or 2-day course)
- CCSK PLUS (2 or 3-day course)
What’s the main difference between the two different formats, aside from the course length? It comes down to practical experience and course exercises.
- The CCSK Foundation format can be delivered over one day, which means you have the time to review theory, but not enough for in-depth class discussion or practical exercises.
- The CCSK PLUShas everything presented in the CCSK Foundation format, but with more time to really drive home the major topics and learning objectives with course exercises/activities. Quite literally, the following formula applies:
CCSK PLUS = CCSK Foundation + AWS labs
In my personal opinion, a person with limited cloud exposure will find a 1-day crash course to be a complete waste of time. I’ve seen it myself, and that is why as a trainer I don’t usually deliver the course in a single day. However if you are new to cloud and can only do the 1-day session, do yourself a favor and read/understand the guidance v4 document before you take the class. Alternatively, if you’ve been working in cloud for a while and are looking to understand what CSA has to say on cloud security, you would likely prefer the 1-day approach. If you are looking for more info, a lot of these details about the CCSK can be found on Cloud Security Alliance’s website.
CCSK Exam Breakdown
I mentioned the exam was pretty hard at the start of this blog entry. The reason for this has everything to do with the split between tactical and strategic domains of knowledge.
People are either tactical types or strategic governance types. The tactical types enjoy the bits and bytes of computing and that’s totally cool. Then, you have the governance types. These are the managers, directors and others where the mindset is how the business as a whole may be impacted by cloud adoption. One person having a foot in both areas is pretty rare, and that is what makes the CCSK exam so hard. I’ve seen hardcore techies fail, and I’ve seen MBA’s fail.
One thing to note that I’ve heard from heads of training departments has to do with it being an open book exam that is not proctored, rather it is taken online from any location (home/office/hotel). It appears these traits lead some to think less of the exam because it doesn’t seem to be as “legitimate” as closed-book proctored. I still contend properly-written open book exams are legitimate and the exam is tough. I believe it would be impossible to answer 60 questions in 90 minutes if you have to research every question. I would have no problem hiring someone who has a CCSK but not the CCSP.
Continuing Professional Education Credits (CPE)
The CCSK course is CPE eligible. Keep in mind the CPE guidelines for courses are that you must take lunch and breaks into account, meaning a 3-day course winds up netting you 21 CPEs (7 per day). Not bad! Side note- the CCSK does not require CPE maintenance, once you have earned it—it’s yours.
Concluding Thoughts on CCSK
With the updated v4 content, the CCSK remains highly relevant to security professionals who are seeking a course that delivers a general tactical and strategic understanding of the challenges and advantages of cloud. If you are looking for coverage of traditional information security concepts in addition to cloud specific issues, you might want to look at the CCSP.

CCSP| Certified Cloud Security Professional (updated for 2017 version)
The CCSP is, in my humble opinion, more suited for CISSP holders. The CCSP will go into many subjects that are assumed knowledge in the CCSK. For example, the OSI reference model is covered in the CCSP whereas the CCSK assumes you have this knowledge already when talking to encapsulation of packets in an SDN network.
Course Details
The main difference between CCSP and CCSK can be found in three areas: Expanded governance discussion, Datacenter Security and Privacy. A CISSP is expected to understand a wide range of security domains and ISC2 wants to ensure that CCSP certified professionals are fully aware of the governance and security issues that come along with cloud, the datacenter and the privacy of consumers using cloud services. So really, when the dust settles, the following formula pretty much sums up the new CCSP:
CCSP = CCSK + Expanded Governance Items + Traditional Security + Privacy
The CCSP course is typically delivered over a 5-day period.There’s some repetition in the material and you can finish it in the allotted 5 days. I wouldn’t say it can be done in 4 days either.
Course Format
The CCSP course is pretty much 100% lecture. There are no labs at all. Zero. None. Zilch. Nada. Instead, you have a series of Q&A and work-group type of scenarios that are peppered throughout the course. This makes the CCSP a course that could be considered more strategic in nature. I would give the CCSP a 70% strategic, 30% tactical approach; almost the inverse of the CCSK.
Update for 2017 version
(ISC)² updated the CCSP Common Book of Knowledge (CBK) and the course in 2017. The CBK itself is about 150 pages bigger than its predecessor (735 vs 584) This update expands on concepts, introduces new subjects (such as economics of cloud, business requirements, etc.) and new technologies (e.g. DevOps, Containers, etc.), albeit to a lesser technical degree than the CCSK.
CCSP Exam Breakdown
As for the exam itself, I’m under an NDA, so I naturally can’t get into the types of questions they present. I think it would be a fair statement though to say the average CCSP exam candidate is a CISSP holder and would be tested on knowledge of both cloud and traditional data center security concepts.
Continuing Professional Education Credits (CPE)
CCSP is listed as a 40-hour course, so you should be taking home roughly 35 CPE’s. Of note for current CISSP’s is that future CPEs earned apply to both the CISSP and CCSP designations. Keep in mind-the CSA’s CCSK can be substituted for one year of experience in pursuit of the (ISC)2 CCSP Certification.
Concluding Thoughts on CCSP
The latest version of the CCSP expands discussion on strategic issues it doesn’t get into the same depth of tactical discussion that is found in the CCSK. The course is written along the same lines of the CISSP, so coverage includes everything that an Information Security Professional should know to secure an environment, ranging from the physical design of a datacenter up to cloud application security.
CCSK vs. CCSP| Final Thoughts
As I said earlier, I don’t have a bias here. I’ve laid out what I consider to be the strengths of both offerings This table basically recaps some highlights:
| CCSK Course Highlights | CCSP Course Highlights |
| –100% focused on cloud security. | –Covers traditional information security and cloud security |
| –60% tactical, 40% strategic | –70% strategic, 30% tactical |
| –Quicker delivery and more comprehensive review of cloud-specific technologies (e.g. SDN, DevOps, Serverless) | –More comprehensive review of IT security principles along the lines of the CISSP CBK |
| –Less expensive course and exam | –More expensive course and exam |
| –Open book exam online (exam included with training cost) | –Closed book proctored exam at testing center (exam additional charge) |
Which Do I Prefer?
I appreciate the coverage of the CCSP, but if I had to do only one, I would do the CCSK because it is 100% focused on cloud security and architectural patterns as well as cloud-specific technologies are covered in greater depth (even more so after the v4 update). I also prefer how it’s consumed in a shorter time frame (due to aforementioned cloud focus).
If you have the time and resources doing both is not a bad idea either. In that case, I would do the CCSK first then the CCSP (and the CCSK counts as 1 year of experience towards the CCSP requirements, as well). Either way, the only way you can go wrong is by not doing either one.
