Who's More Secure? Who's Not?

Networks in the retail industry are getting more secure with 67 percent of devices having vulnerabilities, down from 81 percent last year. Dimension Data tied that to the industry's response to a rise in cyberattacks, as well as the sector's processing of large volumes of personal information and credit card data.

On the other side, manufacturing networks are less secure, with 73 percent of devices containing vulnerabilities, soaring from 47 percent in 2015. Citing the NTT Global Threat Intelligence Report, Dimension Data said the manufacturing sector is the fifth most likely to be the victim of a cyberattack. "We see a potential risk that, unless the sector strengthens its security posture (patching), it could suffer a rise in security breaches, especially as the industrial Internet of Things becomes more pervasive," the report said.
