Setting clear expectations minimizes disputes and fosters device care.

Password policy

Passwords are the first line of defense against unauthorized access. As such, a robust password policy should emphasize creating complex, hard-to-guess passwords. Furthermore, it should advocate for the periodic changing of passwords, reducing the risk of breaches. Another layer of safety is achieved by incorporating multi-factor authentication, which requires users to provide two or more verification factors to gain access.

These are some useful password policies that are easy to implement:

  • Password Refreshing Periods: It's a practice where users are required to update their passwords after a specified time, usually every 60-90 days. Regularly updating passwords reduces the risk of unauthorized access, as even if someone obtains an old password, it will become obsolete after a short duration.
  • Two-Factor Authentication (2FA): This adds an additional layer of security by requiring two forms of identification before granting access. Typically, this involves a password and a secondary verification, like a text message code or a fingerprint. 2FA ensures that even if a malicious actor gains a password, they won't be able to access the account without the second verification.
  • Password Difficulty: Mandating the use of uppercase letters, numbers, and special characters, along with setting a minimum password length can greatly enhance password strength. By ensuring passwords are complex, it becomes exponentially harder for cyber attackers to guess or crack them using brute force methods.

Proper Internet & Device Usage
