firewalling
Restricting digital access
Firewalling is the practice of blocking or isolating something to prevent unwanted access or spread.
In computing, it refers to using a firewall to filter network traffic and protect systems from intrusion.
The term extends to any deliberate separation: The company is firewalling its research division from outside investors.
In legal and corporate contexts, firewalling means creating barriers between departments to prevent conflicts of interest or information leaks.
