Have you ever sat back and thought about Physical Security? Think about when you leave your house. The first thing you do is lock the door handle and then you lock the deadbolt. That is the simplest approach to physical security and there are two layers of security in that scenario. Most people have more than that with surveillance cameras, security systems, chain locks, etc.
After thinking about the scenario above lets’ relate it to Cyber Security. There are way too many companies out there, who think I have a firewall in place and that is good enough. That is the old way of thinking and it just doesn’t work anymore. Most people do have firewalls in place, but they are only scanning about 20% of traffic coming in and out of their network. The reason for this is most businesses do not configure inspection of SSL traffic and 80% of websites use SSL/TLS now days.
This is a problem because it can allow bad actors to set up what seems like a legitimate site. When a user clicks on a link on the site or downloads something it can have malicious code in it that basically just sneaks in through the back door because your firewall can’t decrypt the traffic.
Security is about layers, just like securing your home on a much larger scale.
