Step 1: Remove everything from the interior. To manually defrost, you need to clean out the interior of your refrigerator and freezer entirely. Keep items that need to stay chilled in a cooler with ice. Step 2: Circulate warm air. Open both doors and allow the warmer, room-temperature air to flow into the freezer and refrigerator to begin the defrosting process.
Authentication and access control attacks. Common attacks against access control are dictionary attacks, brute force attacks and spoofed logon screens. These are programs with built in dictionaries.

Users who need access are added or removed from the appropriate security groups as needed, and the access control lists change infrequently.
