Which of the following is NOT a commonly required cybersecurity task?

The task that is not commonly required in the realm of cybersecurity is increased physical mail monitoring. While monitoring physical mail could be relevant in specific scenarios, it is not a standard component of typical cybersecurity protocols. Cybersecurity primarily focuses on protecting digital information and systems from unauthorized access, attacks, or damage, which renders physical mail monitoring less central to these efforts.

In contrast, implementing multifactor authentication is a widely acknowledged practice designed to add an additional layer of security beyond just a username and password. Regular security awareness training is essential in ensuring that employees are educated about potential threats and best practices, thereby reducing risks from human error. Applying encryption during data transfer is a fundamental cybersecurity measure that helps secure sensitive information and maintain confidentiality during transmission. Each of these tasks addresses the digital security landscape directly, making them critical components of an effective cybersecurity strategy.
