Remote Access Control allows users to access and manage computer systems or networks from a distance. This technology is commonly used in businesses to enable employees to work from home or other locations, ensuring they can connect to their office systems securely. It typically involves software or hardware solutions that authenticate users and grant them permissions to access specific resources. Common methods include VPNs (Virtual Private Networks) and RDP (Remote Desktop Protocol), which help maintain security while providing flexibility in accessing information and applications remotely.
