When does it pay to think like a criminal? When your cybersecurity doesn’t. For example, Gartner expects 50% of network attacks to come over encrypted traffic in 2017. This happens because systems or devices blindly trust keys and certificates regardless of whether they are valid or compromised. Bad humans can insert rogue keys or certificates which fool the systems and voila, the balance is upset. It’s going to take some good humans asking the right questions to set things straight.
Computers can give you an alarming amount of data. But they simply can’t get into the mind of criminals. Only humans can ask the questions to solicit the answers they need to track down human invaders in their networks.
In a recent article, Financial Times explores the human element of cyber security. Venafi Chief Strategy Officer, Kevin Bocek weighs in on the human dilemma, “The human brain can’t process the gigabytes of data but it can ask the right questions and it knows what doesn’t look right and how the machine can be fooled.”
The first question you should ask yourself is about the safety of your encrypted traffic. Are your keys and certificates available for security technology that does SSL inspection? “You have growing complexity and the bad guys are getting better and better at hiding their tracks,” said Bocek. “You need to make sure your encrypted traffic is not a safe haven for sophisticated cybercriminals.”
You need to make sure that you can see anything unusual that may be happening in your encrypted traffic. You can then begin asking more detailed questions about the behavior of your keys and certificates. How many do I have? Where are they located? Who has access to them? Are they behaving normally? The answers will help you close in on potential human invaders and lock then out of your network.
This will become a greater challenge as your network boundaries become less defined. With mobile workers and cloud computing, you’re going to have to rely more on authentication and authorization than on firewalls and intrusion detection. Respect your keys and certificates and they will help you control the encrypted traffic that leads to your valuable data.
Do you know where all of your keys and certificates are and how they are being used?
