Tired of hand-editing YAML files just to tell Alexa which Home Assistant devices to control? I built an automation to generate the list. It makes life simpler every time I add a new smart plug. Here's how I did it.

Per Rene Malmgren at the #OpenSSL Conference, the left side is known as easily able to be bypassed by attackers, while the right side creates trouble for attackers and is the starting point for security.
Slide: WHAT WORKS, WHAT DOES NOT. Left Side • Password based authentication • Do I realy have to comment? • Any OS level administrative access control. • They have root lits as COTS. • Cloud bases authentication services. •You cant outsource your problems, only insource others. • Fine grained access control. •No way you can understand what you are doing. • Any closed source stuff. •They have been caught so many times to sel vulnerobilties. Complex stuff. • If you cant audit it its not safe. VDI. Free beer stuff. If you are not paying for it, you are not the customer, you are the product for sale. • Pain. • If its not convenient its not secure. • Access tokens Right Side • Hord information segregation. • At the miltory work with this. • Pubic, blockchoins. • Bilions of stake, work wel. • Correctly configured crypto. • We have seen them work very hard to disoble them. • Hierorchical Keystore. • All blockchoin wolets use them. • Type 1 hypervisor. • Requirement from NCSC (Uk). • Defence in debt. • Every miltory does this. • Correctly configured 2FA. • Surprisingly. • Rust. • Guardion protocol: • TLS, SSH, GPG, IPSEC.

To help people better understand the risk of ignoring post-quantum cryptography and the challenges involved in getting there we got to play Post-Quantum Trails at the #OpenSSL Conference

I love how being there for the world has been acted on through #OpenSSL sponsoring and supporting the Polar Bears at the Brno Zoo
