HSTS Missing From HTTPS Server

Info Nessus Plugin ID 84502


The remote web server is not enforcing HSTS.


The remote HTTPS server is not enforcing HTTP Strict Transport Security (HSTS). The lack of HSTS allows downgrade attacks, SSL-stripping man-in-the-middle attacks, and weakens cookie-hijacking protections.


Configure the remote web server to use HSTS.
