“Never let the same dog bite you twice.”
Before I discuss securing SIP, I want you to imagine a bank. Every bank I know has a sturdy door equipped with a good lock and some form of alarm system. Inside the bank, it’s not uncommon to have a trained security guard. The tellers have access to alarm buttons that can be silently tripped. Behind the tellers there is a vault for safety deposit boxes and the bulk of the on-premise cash. Every safety deposit box has been secured with a two-key system. Beyond physical security, bank employees are trained in how to recognize and respond to security threats.
In my latest guest blogging article, I explore a number of different ways you can add layers of security to SIP communications. It’s worth a look.
