Why is PKCE secure?
PKCE provides dynamic client secrets, meaning your app’s client secrets can stay secret (even without a back end for your app). PKCE is better and more secure than the implicit flow (AKA the “token flow”). If you’re using the implicit flow, then you should switch to PKCE.
Does Keycloak support SAML?
Keycloak uses open protocol standards like OpenID Connect or SAML 2.0 to secure your applications. Browser applications redirect a user’s browser from the application to the Keycloak authentication server where they enter their credentials.
How does PKCe mitigate auth code interception attack?
PKCE mitigates this by requiring shared knowledge between the app initiating the OAuth 2.0 request (request auth code) and the one exchanging the auth code for token. In the case of an Auth Code Interception Attack, the malicious app does not have the verifier to complete the token exchange.
Why is it important to know about PKCe?
The reason PKCE is important is that on mobile OS, the OS allows apps to register to handle redirect URIs so a malicious app can register and receive redirects with the authorization code for legitimate apps. This is known as an Authorization Code Interception Attack.
How to protect against man in the middle attacks?
An attacker could run malware on the endpoint itself, sniff for traffic on a layer 2 adjacent network segment and potentially strip SSL/TLS altogether, inject malicious entries into the target’s ARP cache, or even compromise the routing table of the upstream router serving as the gateway for the network.
Is the HTTP protocol vulnerable to man in the middle?
HTTP is not the only protocol vulnerable to man-in-the-middle attacks. In 2018, a vulnerability in the Bluetooth protocol was discovered ( https://www.kb.cert.org/vuls/id/304725) that allows an attacker to intercept Bluetooth communications encrypted by SSL/TLS.
