Remote access of a computer for the purpose of support and maintenance is referred to as remote access support. Remote access support can be carried out using third-party software, a web application or a common solution built into the operating system of both machines.
Remote access support is used in corporate environments, as well as by service and support staff to troubleshoot their company's products. In some cases, remote access support is also used for guided user training of various tools. Remote access and associated support systems are built over a high-security tunnel that ensures security of data and high-level access control.
