Yordan Rouskov, a Bulgarian software architect living in the United States, has published a book titled Cloud Application Security Essentials with Azure: Azure application security, confidential computing, app identity, authentication, and authorization, eurochicago.com reported.

“As applications are becoming more dependent on cloud components and services, it is essential to grasp the security implications for your application's architecture and the underlying platform to prevent breaches and maintain system integrity,” Ruskov said.

Born in Sofia, Rouskov graduated from the city’s English Language School in 1986, going on to study computer science at the Technical University of Sofia and Colorado State University. He now lives in Seattle, Washington, and has 30 years of professional experience, mostly at Microsoft, specialising in digital identity.
