What is a storage channel?
Storage channel is a hidden computing channel that allows one process to write to the site of a storage on a computer or network and allow another process to read information about the storage site by another process. As a hidden channel, the storage channel has the ability to transmit data between objects that would otherwise be segregated by security restrictions in the computer operating system. This provides another level of flexibility of programming, but when using hidden channels can be used to undermine the system security.
They imagine a storage channel as two children who go through notes in the classroom. According to the rules set out in the operating system - the class teacher - children should not speak. By sliding the information, out of the sight of the operating system, it creates an otherwise inadmissible communication line.
The storage channel is a two-way connection. So while one process rewrses information to a hard drive or other storage site on your computer, it approaches the other process and read information from the same storageHo equipment. This constant of transmitting information back and forth offers programmers another data exchange method on the computer. It provides the medium for attack on the system if programmers are dishonest.
Since the computer operating system has no knowledge that information is passed across the storage channel, it is quite possible for a hacker to slip personal or sensitive data across this type of channel. In addition, a hacker could also manipulate data within the system in the same way. Theoretically, someone would undermine the system in this way with the financial records of the organization and at the same time to leave the wrong information about "figurines".
It is a type of hidden channel from IT, the possibility of transmitting storage channel data cannot be completely eliminated. However, secure operating systems can monitor potential storage channel activity using pattern recognition tools to see if unusual system in SystemIt can be information moving along the storage channels. Think about it as listening to how two people in different cells communicate by clicking on the wall; If only one or two knocks have been heard for a long time, it is likely that it was a random act. However, if knocking on the walls is heard regularly and rhythmically, it is likely that information is exchanged.
