An organization can implement certain encryptions to prevent the hijacking of a users session. Cybercriminals use different methods to steal sessions. Ultimately, this means that even highly protected systems with stronger authentication protocols and less predictable session cookies, such as those housing financial or customer information, may only be as protected as the weakest link in the entire system. A session is the communication between two systems, which remains active until the user ends the communication. The attacker then uses the cookie to log in to the same account owned by the victim but instead from the attacker's browser. In effect, a hijackerfools the website into thinking they are you. Further, when authorized users surf one or more protected pages, they should be educated to use HTTPS websites in spite of HTTP. Using this approach can have the disadvantage of false alarms causing problems for legitimate users. In general terms, a session ID is basically an identification string (generally a lengthy, random, alpha-numeric code) that is fully communicated between the client and the server.
