Q

SCADA/ICS Security concerns

A

These specialized control circuits don’t have any built-in security and should be secured on a separate network that is not connected to the internet

Q

Name 3 security risks are associated with IoT/Smart Devices?

A
  1. Not designed with security as a primary concern
  2. OS often can’t be upgraded for security patches
  3. Place on isolated network to prevent use as pivot to compromise more sensitive devices

Q

Define MFP and security risks

A
  1. Multi-function device, i.e. printer, scanner
  2. Information, such as printed documents, scanned images, call history, is often stored in local memory on the devices and could be compromised

Q

Define Real Time Operating Systems (RTOS) and security risks

A
  1. used for automobile and industrial controls, i.e. anti-lock brake system on cars
  2. Often don’t have visibility into the security of the OS running on these devices

Q

Security risks associated with narrow-band communications and the systems that typically use them

A

Often SCADA devices use narrow-band for wireless communication over long distances. Subject to interference which may cause damage due to lack of communication with these devices and what they control
