Which of the following best describes the purpose of endpoint security?

Endpoint security primarily focuses on protecting devices that connect to a network, such as computers, smartphones, tablets, and other endpoints. The main aim is to defend these devices against various cyber threats—including malware, ransomware, and phishing attacks—that can exploit vulnerabilities within them. Given the increasing number of devices accessing networks, endpoint security is critical as these devices can serve as entry points for malicious actors attempting to breach a network's defenses.

This protection typically includes a combination of antivirus software, firewalls, intrusion detection systems, and encryption, all designed to ensure that each endpoint is secured against potential threats. By implementing endpoint security measures, organizations can significantly reduce the risk of data breaches and ensure overall network integrity.

The other options, while related to aspects of security, do not capture the comprehensive scope of endpoint security, which primarily targets devices used directly by end-users.
