Introduction

What is python3-flask-talisman
python3-flask-talisman is:
Talisman is a small Flask extension that handles setting HTTP headers that can help protect against a few common web application security issues.
The default configuration:
- Forces all connects to https, unless running with debug enabled.
- Enables HTTP Strict Transport Security.
- Sets Flask’s session cookie to secure, so it will never be set if your application is somehow accessed via a non-secure connection.
- Sets Flask’s session cookie to httponly, preventing JavaScript from being able to access its content. CSRF via Ajax uses a separate cookie and should be unaffected.
- Sets X-Frame-Options to SAMEORIGIN to avoid clickjacking.
- Sets X-XSS-Protection to enable a cross site scripting filter for IE and Safari (note Chrome has removed this and Firefox never supported it).
- Sets X-Content-Type-Options to prevent content type sniffing.
- Sets a strict Content Security Policy of default-src: ‘self’. This is intended to almost completely prevent Cross Site Scripting (XSS) attacks. This is probably the only setting that you should reasonably change. See the Content Security Policy section.
- Sets a strict Referrer-Policy of strict-origin-when-cross-origin that governs which referrer information should be included with requests made.
