In this video I talk about a super important topic, which is security in Kubernetes and what are some of the best practices for securing your Kubernetes cluster.
The big challenge that we see in terms of Kubernetes security is that it's already so challenging to set up a Kubernetes cluster and to configure it to deploy the applications in it, that security often becomes the afterthought, adding on top of that already complex configuration. However we can't deny the importance of security, especially when the systems are so complex!
Cloud applications actually become a very attractive target to a lot of hackers and this growing number of cloud native applications mostly use Kubernetes as a platform and that's where the relevance of knowing how to secure Kubernetes clusters comes into play.

Awesome!
1. Do Image Scanning for vulnerability
2. Avoid root user for running container
3. Manage User & Permission - RBAC
4. Use Network policies or service mesh
5. Encrypt Communication
6. Secure secret data
7. Secure etcd
8. Backup & Restore
9. Configure security policies
10. Disaster Recovery
You're right, Nana is very good presenting concept basis for developer knowledge, especially when presenting strength weakness opportunity threat (SWOT) analisis kind of comparison of different DevOps tools👍
So basically, protection at 3 layers,
1. Network
2. Application
3. Data
All above 10 points are in these category
Nana, your explanation skills are just great, as usual! 🙏❤️
Thanks so much David! 💙
Best cloud and K8S security content. Bravo. Thank you for sharing.
The more I watch your youtube videos, more it clarify basics of each K8s components!!! you are the best...!
I learned more from this 30 Minute video than I did the entire Linux Foundation Kubernetes Security Essentials course. Thanks!
Fantastic overview! Just what I was looking for. Thank you. 🙏
Nana, I love the way you explain each and every point. You are the best Teacher in the world. Thanks and appreciate all your hard work.
These security best practices are at root based on several infosec standards such as iso27001, and you have applied these for K8s beautifully.
Very helpful and made my day since I’ve been figuring out how to do this and I learned it so quick as I clicked into this video,thanks girl
Glad it was helpful Kianne! :)
Really awesome, appreciate how you organized the content. Happy to learn good things.😀

What a fabulous explanation, thank you kindly.
Happy to hear! Appreciate your positive feedback! 💙
knowledge ++
many many ty
Thank you
Thanks!
Nice informative video !
Nice Explanation..
Also one of the best practices to secure Etcd is to encrypt it..
Thank you so much for these valuable information
My pleasure! Appreciate your comment!
Really helpful
Great video Mam !!!, a very core feature which is rarely being used in companies for implementing k8s security,
kindly also cover Locking Down Kubelet as its a backdoor for api server & image signature as its must to make sure that image is a legitimate one, Thank You
Awesome bro
Great video👌
Great explanation, this is top level content.
Thanks Steven :)
Thanks nana
Great - Thanks for sharing.
My pleasure! :)
Thank you for this awasome video
My pleasure! 💙
Great video. Thank you so much. Can you suggest a enterprise grade tool that helps with most of these best practices rather than using different tools for each type
Bery good Video nana
First of all this was a great video on this series. I have a question related to the point 10. You marked this as result of a successful attack but, if you just restore the cluster, could get attacked the same way so, there are any tool that lets you identify how it happened to solve the related security flaws? Thank you in advance.
Hi, first of all I would like to thank you for your great effort to explain us the k8s cybersecurity issues and how to mitigate threats related to its deployment, just one the most important thing that also can improve the K8s security is the log management, it give you the possibility to control and monitor security issues in real time using for example syslog protocol to collect and treat them in a centralized areas. So, if you can focus on this issue in next time. Thanks.
Great Stuff as usually
Glad you enjoy it! Thanks 😊
Hi thanks for these videos. I have a request. If you find some time can you please make a video on how you learn a technology/concpet this thorough? For me, it takes couple of times reading and trying out before I understand the basics properly. If you have a shortcut, we would love to know.
Excellent
Thank you!!
You have been great Nana - really appreciate you giving the right amount of details. I wanted to ask while I understand 3rd party product was mentioned for data recovery, I wanteed to ask if Volume Storage can help in protecting or recovering the application/config data in any which ways during a cyber event. If anyone can hep - wouldd be appreciated.
i love u nana
I really like the way you teach, I prefer your videos over udemy .....thanks a lot
for scan image, you could use anchore
thanks for the nice video! i habe got 2 doubts after watching the video:
1. in point 5 you mention that pods traffic is unencrypted by default. is this only true for communication inside the cluster, i.e. is the host to host communication for both control plane and pods elements encrypted from the outside? if this is not the case, is it necessary to setup a VPN mesh between the k8s nodes or would that be an unusual overhead in regular k8s deployments?
2. how about securing network access to cluster and its services on a TCP level? can port 6443 remain unprotected? should administrator always access the cluster protected services via port forwarding or is it best to publish ingresses on a protected subnet and then setup a VPN to push that subnet to authorized users? what are best/common cloud native practices here? is there any helm chart for that?
thanks
Thank you for the video! 🙏
I’m interested in using Hashicorp Vault. Could you maybe make a video about it to? :)
Thank you for your suggestion. Yes, we are thinking about making video about Vault.
Great video! It would be nice if you inform the viewer whenever, you jump to a sponsored or affiliated component, such that the viewed knows that your view on that component is biased like with Kasten K10.
Thanks for your valuable feedback! Sure, will try to make it clearer in the videos, when talking about the sponsored tool.
hey nana, i like your content, do you have an advice for including security testing in the pipeline, like vulnerability scanning and compliance checks? For example how do i include cis benchmarks and vuln scanning and define thresholds that prevent unsecure workloads from going to production?
Nice question
Image scanning happens in CI/CD and also Image registery regularly, we can consider to do such scanning at appropriate stage in deployment. Also we can consider to attach digital signature when run scanning is completed just before to start tranfer the image upon pull Image request from registery , and verify it at appropriate stage during deployment workflow.
Please share your thoughts. Thank you!
Hi Nana,discuss about what are the career paths in software field,it will be helpful,to set goal beside that
Will consider. Thanks for suggestion!
would have been helpful to mention more details on scanning... static, dymanic, SCA, and Docker Scout.
One important point missing was a firewall between your cluster and the outside world.
I've just started a job as DevSecOps and I have zero experience. I'm buying the course as it comes out!
Good to hear! I'm sure it can be pretty challenging.
Just to help drive home the misconception of the security in cloud in general. Each cloud provider has a shared responsibility model. The cloud provider is responsible for the security OF the cloud and the customer is responsible for the security IN the cloud :)
Thanks for sharing :)
Hi nana was attended 3 times interview within a span of 1 month in tcs but 3rd time i got selected and they released offer and joining date too while doing background check previous two attempts they will consider? Normally they will. Check the candidate before attending interview right wether candidate is attended or not like?
Get NeuVector...done :)
How to use regex in audit policy in k8s ?
💯💻
I'm enchanted by this content. I had the pleasure of reading something similar, and I was completely enchanted. "Mastering AWS: A Software Engineers Guide" by Nathan Vale
Does any one else feels like crying? I found peace finally!!!!
How to delete already pulled images from cluster to release space .
actually sa can be used for human also
Kubernetes secrets are not stored in ETCD. Secrets in k8s are stored in a separate "Secrets API" object in encrypted format within k8s.
Just pointing out that at 19:30 you forgot a "=" at the end of your mongo-password secret. In fact, it should be "bW9uZ29wYXNzd29yZA==". Maybe I do have too much free time 😅?
😀 great attention to detail! 👍

Encryption: AWS engineers when using their KMS have a copy of the private key. So they become the insider threat. See arrest of Paige Thompson, AWS engineer who release Captial One customer data. Use you're own key management system.
This is exceptional in every way. I read a book with similar content, and it was exceptional in every way. "Mastering AWS: A Software Engineers Guide" by Nathan Vale
After reading the NSA/CISA Kubernetes Hardening Guide, it's a no thank you. Managed Kubernetes platforms ftw. Especially D2IQ
not sure if actual tutorial or a list of product placements ...
There is a single sponsored product in the video, which is K10. And I explicitly mention that in the video, that it's sponsored. All other tools are just examples. Plus, you can also ignore the tools and just focus on concepts. As I mentioned in my previous video, tools come and go, concepts stay. I hope this makes it clear.
