An MDM (Mobile Device Management) solution enforces compliance requirements such as OS patch levels, security policies, and configuration standards on all company phones.

Time-based one-time password (TOTP) MFA apps rely on accurate clock synchronization.
Traveling can desynchronize the device's clock, causing generated codes to be invalid. Ensuring the smartphone's date/time (and time zone) are correct will typically restore MFA functionality immediately.

While strong passwords and encryption are important, multifactor authentication (MFA) provides the most effective defense against external threat actors targeting cloud-based services. By requiring a second verification step, such as a push notification, one-time code, or hardware token, MFA ensures that even if credentials are compromised, attackers cannot gain access without the additional factor. This significantly reduces the risk of unauthorized account takeovers in cloud environments.

Ransomware is malware that encrypts a user's files and then demands payment (a ransom) in exchange for the decryption key. The user's inability to open the files and the message indicating they're encrypted are classic signs of a ransomware attack.

Requiring another employee to be present during server configuration is a control designed to prevent or detect malicious actions from an internal employee, mitigating insider threats.
