What is an allowlist / allowlisting?
Allowlisting is a cybersecurity practice that creates a list of approved, trusted applications, IP addresses, or users, permitting only them to access a network or run software while blocking all others. It operates on a "deny-by-default" principle, significantly enhancing security by reducing the attack surface.
