Description
Technical Field
The present invention relates to the field of mobile device management technologies, and in particular, to a time calibration method, apparatus, device, and medium.
Background
The self-contained office of equipment (BYOD) refers to an office with its Own equipment, including personal computers, mobile phones, tablets, etc. BYOD allows smartphones and tablets originally designed for individual consumers to be used by enterprises to carry critical services and core applications. Meanwhile, the BYOD policy is also introduced into the enterprise in a large amount, and conventional Internet Technology (IT) management is challenged in terms of BYOD management aiming at the continuous emergence. Thus, Mobile Device Management (MDM) has come into play.
MDM is a platform technology for enterprise IT to transition to the mobile internet, helping enterprises extend IT management capabilities from traditional computers to mobile devices and even mobile applications. The MDM may perform role-based management and configuration of enterprise mobile devices and employee-owned mobile devices and ensure security of enterprise content stored in the devices. The MDM provides complete mobile equipment full life cycle management from all links of equipment registration, activation, use and elimination so as to meet the management and control requirements of enterprises on mobile office terminals.
The MDM provides time control of the mobile device, i.e., controls that specify the mobile device for a specified period of time (e.g., prohibit logging into a specified website, prohibit using certain software, prohibit using a camera, etc.). In order to avoid the time control of the MDM, the device user usually changes the mobile device time to violate the enterprise rules, thereby gaining profits and bringing impacts and hazards to the enterprise rules, benefits and safety.
