Securing Your Cookies
Cookies carry sensitive data like session IDs. If not properly secured, they can be stolen (XSS) or used for unauthorized actions (CSRF).
01
HttpOnly & Secure
HttpOnly prevents JavaScript from accessing cookies, mitigating XSS attacks. Secure ensures cookies are only sent over encrypted HTTPS connections.
02
SameSite Attribute
SameSite controls when cookies are sent with cross-site requests. Setting it to 'Strict' or 'Lax' effectively blocks most CSRF attacks.
Critical Security Flags
HttpOnly
Prevents client-side scripts from accessing the cookie. Essential against XSS.
Secure
Ensures the cookie is only transmitted over secure HTTPS connections.
SameSite
Strict, Lax, or None. Controls cross-site cookie sending to stop CSRF.
