Web applications rely on numerous underlying infrastructure components, including public key infrastructure (PKI). Discover the overall web application ecosystem with a focus on the OWASP Top 10 2017. Key concepts covered in this 13-video course include how to identify common web application security issues and their impacts; how tools such as Nmap, Metasploit, and Nessus can be used for benign and malicious purposes; and how the OWASP Top 10 helps to secure web applications. Next, you will learn the OWASP security tools; how to identify common web application architecture and development techniques and the role that clients and servers play; and how TLS supersedes SSL and tools such as SSL Labs can test PKI implementations. Learners then observe how PKI certificates can enhance web application security; how to configure HTTPS bindings for Microsoft IIS websites; and how to configure Microsoft IIS websites to require client certificates. Finally, learn how to configure HTTPS bindings for Linux Apache websites, and how to scan a public Internet site's PKI configuration to determine the site's security posture.
