Locking a session ID to the client's IP address is a simple and effective measure as long as the attacker cannot connect to the server from the same address, but can conversely cause problems for a client if the client has multiple routes to the server (e.g. redundant internet connections) and the client's IP address undergoes Network Address ...
In computer science, session hijacking, sometimes also known as cookie hijacking, is the exploitation of a valid computer session—sometimes also called a session key—to gain unauthorized access to information or services in a computer system. In particular, it is used to refer to the theft of a magic cookie used to authenticate a user to a ...
In computer science and networking in particular, a session is a time-delimited two-way link, a practical (relatively high) layer in the TCP/IP protocol enabling interactive expression and information exchange between two or more communication devices or ends – be they computers, automated systems, or live active users (see login session). A ...

According to Wheeler, the most efficient technique which could have prevented Heartbleed is a test suite thoroughly performing robustness testing, i.e. testing that invalid inputs cause failures rather than successes. Wheeler highlights that a single general-purpose test suite could serve as a base for all TLS implementations.
