How is "endpoint security" best defined?

Endpoint security is best defined as the protection of end-user devices such as computers and mobile devices from various threats. This involves implementing a range of security measures to safeguard these devices against malware, unauthorized access, and other cyber threats. Endpoints are often the primary targets for cybercriminals since they serve as points of access to networks and sensitive data. As such, securing these devices is crucial in maintaining a strong overall security posture for any organization.

The focus on endpoint security includes the use of antivirus software, firewalls, intrusion detection systems, and regular software updates to ensure that devices are well-protected against evolving threats. This approach emphasizes the importance of securing all devices that connect to the network, which is essential in today's mobile and remote work environments.

Other options highlight important aspects of security, but they do not encapsulate the specific focus of endpoint security. For instance, securing data in the cloud pertains more to data protection strategies rather than device protection. Monitoring network traffic relates to network security and threat detection without a specific focus on individual devices. Encrypting data for secure storage is concerned with data confidentiality and integrity rather than the security of the devices themselves.
