Ensure Git access is limited based on IP addresses

MédiaNível 2Automatizadagitlab

Descrição

Limit Git access based on IP addresses by having a allowlist of IP addresses from which connection is possible. Allowing access to Git repositories (source code) only from specific IP addresses adds yet another layer of restriction and reduces the risk of unauthorized connection to the organization's assets. This will prevent attackers from accessing Source Code Management (SCM), as they would first need to know the allowed IP addresses to gain access to them.
