<p id="permission_0004__p16835182716203">The following method can be used if you need to assign permissions of the <strong id="permission_0004__b549118181508">VPC FullAccess</strong> policy to a user but also forbid the user from deleting VPCs. Create a custom policy for denying VPC deletion, and assign both policies to the group the user belongs to. Then the user can perform all operations on VPC except deleting VPCs. The following is an example deny policy:</p>
