Many of the security options in RFC 2617 are optional. If quality-of-protection (qop) is not specified by the server, the client will operate in a security-reduced legacy RFC 2069 mode; Digest access authentication is vulnerable to a man-in-the-middle (MITM) attack. For example, a MITM attacker could tell clients to use basic access ...
The second set use a Diffie–Hellman key exchange authenticated with a pre-shared key. The third set combine public key authentication of the server with pre-shared key authentication of the client. Usually, Transport Layer Security (TLS) uses public key certificates or Kerberos for authentication. TLS-PSK uses symmetric keys, shared in ...
The myIpAddress function has often been reported to give incorrect or unusable results, e.g. 127.0.0.1, the IP address of the localhost. [5] It may help to remove on the system's host file (e.g. /etc/hosts on Linux) any lines referring to the machine host-name, while the line 127.0.0.1 localhost can, and should, stay.

The commercial version supported analysis of PHP and Java code. In order to identify security vulnerabilities that are based on second-order data flows or misplaced security mechanisms, it used abstract syntax trees, control-flow graphs, and context-sensitive taint analysis [7] It could automatically detect 200 different vulnerability types, code quality issues and misconfiguration weaknesses.
Application-Layer Protocol Negotiation (ALPN) is a Transport Layer Security (TLS) extension that allows the application layer to negotiate which protocol should be performed over a secure connection in a manner that avoids additional round trips and which is independent of the application-layer protocols.
The index attribute of an <md:AssertionConsumerService> element is used as the value of the AssertionConsumerServiceIndex attribute in a <samlp:AuthnRequest> element. The Binding attribute of the <md:AssertionConsumerService> element is a standard URI specified in the SAML 2.0 Binding specification (SAMLBind [ OS 5 ] ).

A session key is a single-use symmetric key used for encrypting all messages in one communication session.A closely related term is content encryption key (CEK), traffic encryption key (TEK), or multicast key which refers to any key used for encrypting messages, contrary to other uses like encrypting other keys (key encryption key (KEK) or key encryption has been made public key).
