The most popular culprits for carrying out a session hijacking are session sniffing, predictable session token ID, man in the browser, cross-site scripting, session sidejacking, and session fixation. If encryption is not used (typically SSL), Session IDs are transmitted in the clear and are susceptible to eavesdropping. All too typically, websites use algorithms based on easily predictable variables, such as time or IP address, in order to generate the Session IDs, causing their session IDs to be predictable. Session IDs are commonly stored in cookies, URLs and hidden fields of web pages.īesides the useful functionality of session IDs, there are several security problems associated with them. When the session is destroyed, the user's data should also be deleted from the allocated memory space.Ī session ID is an identification string (usually a long, random, alpha-numeric string) that is transmitted between the client and the server. The session is destroyed when the user logs-out from the system or after a predefined period of inactivity. The session is kept "alive" on the server as long as the user is logged on to the system. When a user logs into an application, a session is created on the server in order to maintain the state for other requests originating from the same user.Īpplications use sessions to store parameters that are relevant to the user. A session is a series of interactions between two communication end points that occurs during the span of a single connection. HTTP is stateless, so application designers had to develop a way to track the state between multiple connections from the same user, instead of requesting the user to authenticate upon each click in a web application. The attacker enjoys the same server access as the compromised user because the user has already authenticated to the server prior to the attack.ĮBookTLS Machine Identity Management for DummiesGet it Now Once the attacker hijacks a session, they no longer have to worry about authenticating to the server as long as the communication session remains active. Once the user's session ID has been accessed, the attacker can masquerade as that user and do anything the user is authorized to do on the network.Ī byproduct of this type of attack is the ability to gain access to a server without having to authenticate to it.
