Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
2. Looking for powerful airflow against high system impedence?
JMC has you covered.
JMC’s 40x56mm counter-rotating fan is ideal for high-density 1U servers and power sup-
plies or any other high-density electronic enclosures. Counter-rotating technology creates
extremely powerful and concentrated airflow while maintaining high efficiency and an out-
standing performance (PQ) curve.
JMC’s 40x56mm CR fan possesses the following attributes:
- 20,000 RPM - 3.1 Amps at 12 Vdc
- 40 CFM - Life data of 70,000 hours L10 at 40C
- 3.4 inches of H20 - 4 ball bearings
- 69 dBA - UL & TUV certified and 100% RoHS compliant
Features:
- Counter-rotation allows for much better performance than
standard tube-axial fan against high system impedance
- Pulse Width Modulation (PWM) available for both motors
independently or in parallel
- Of the following two features, one can be assigned to both
motors, or one of each can be applied by request:
- Tachometer output
- Locked rotor signal
