A bastion host is the one server you expose to the Internet on purpose—hardened, watched, and forcing all access through a single fortified point.
Every server with an open SSH port is being attacked right now. Here's how to make sure those attacks fail.
Stop typing the same long SSH commands repeatedly. The config file lets you define connection settings once, then connect with three-character shortcuts.
