What security measure is taken regarding external computer ports?

Deactivating external computer ports is a critical security measure aimed at preventing unauthorized access and potential data breaches. By disabling these ports, organizations can mitigate risks associated with the connection of external devices, such as USB drives or other peripherals, which could introduce malware or facilitate data theft. This approach helps maintain a secure environment by ensuring that only authorized devices are able to connect to the network or systems, thereby protecting sensitive information and maintaining the integrity of the organization's infrastructure.

In contrast, enabling ports for convenience can lead to vulnerabilities, as it increases the likelihood of accidental or malicious data exposure. Restricted access, while a helpful measure, does not eliminate the risks associated with active ports, and requiring a password for use may add a layer of security, but it is not as effective as completely disabling unused ports. Therefore, deactivating external computer ports stands out as the most effective security strategy among the options presented.
