Jonathan (Koz) Kozolchyk, General Manager for Certificate Services at AWS, joins Corey on Screaming in the Cloud to discuss the best practices he recommends around certificates. Jonathan walks through when and why he recommends private certs, and the use cases where he’d recommend longer or unusual expirations. Jonathan also highlights the importance of knowing who’s using what cert and why he believes in separating expiration from rotation. Corey and Jonathan also discuss their love of smart home devices as well as their security concerns around them and how they hope these concerns are addressed moving forward.
