Spend a full day to understand both the theory and practice of SSL/TLS.

Designed by the author of the much acclaimed Bulletproof SSL and TLS, this practical course will teach you how to deploy secure servers and encrypted web applications during a day packed with theory and practical work. We’ll focus on what you need in your daily work to deliver best security, availability and performance. And you will learn how to get an A+ on SSL Labs!

• Understand threats and attacks against encryption
• Identify real risks that apply to your systems
• Deploy servers with strong private keys and valid certificates
• Deploy TLS configurations with strong encryption and forward secrecy
• Understand higher-level attacks against web applications
• Use the latest defence technologies, such as HSTS, CSP, and HPKP
