In a zero-trust environment, trust is never assumed, hence it's essential to continuously validate every request as if it originated from an untrusted network. Verifying the user's recent activity for anomalies ensures that the request hasn't been made by a malicious actor who has compromised the developer's credentials despite MFA being enabled. Enabling MFA is incorrect because it's already implemented for the developer. Moving the code repository to a less secure environment goes against the zero trust principle of 'never trust, always verify' and unnecessarily exposes sensitive resources. Restricting access to office hours does not provide the dynamic and context-aware security evaluation needed in a zero trust approach.
