ShouldWeBeConcernedAboutIoT?

• It’s just another desktop/laptop/computer, right?

• Imagine your network with many more computers that you

don’t manage or even know they exist.

• All of the same issues we have with access control, vulnerability

management, patching, monitoring, etc.

• Any compromised device is an attack vector on the network

16

Why Attack IoT? Easy Target? (Naahhh!)

• Default, weak, and hardcoded credentials

• Difficult to update firmware and OS• Lack of vendor support for repairing vulnerabilities

• Vulnerable web interfaces (SQL injection, XSS)

• Coding errors (buffer overflow)

• Clear text protocols and unnecessary open ports• DoS / DDoS

• Physical theft and tampering17

IoT GetAttacked,DoWeCare?

• SendSpam(InternalUsersorEvenWorse,toExternalUsers).

• ServeaMalware• CoordinateanAttackAgainstaCriticalInfrastructure

• WorkasanEntryPointtoLaunchAnotherAttack
