An "endpoint" refers to a device or node that serves as a point of communication in a network. This can include computers, smartphones, or any other device that connects to the internet or a local network. Endpoints are crucial for data exchange, allowing users to send and receive information. In the context of cybersecurity, endpoints are often targeted by threats such as malware or hacking attempts. Protecting these endpoints is essential for maintaining the security of the entire network. Solutions like antivirus software and firewalls are commonly used to safeguard these devices from potential attacks.
