Newswise — Detecting and preventing data breach requires a broad range of security mechanisms, strong commitment from leaders, and continuous effort from everyone involved, says Virginia Tech cybersecurity expert Daphne Yao.

“The biggest and constant fear for large organizations is data breach. As perpetrators are invisible, anonymous, and appearing omnipresent, this fear is indeed understandable and justified,” says Yao, an associate professor of computer science.

“There are multiple ways to reduce data breach risks in enterprises. The recent massive Equifax data breach likely involved multiple points of failure in the enterprise cyber ecosystem. Several weaknesses have probably existed in their cyber infrastructures for a substantial period of time.”

Yao says company executives and upper managers must understand what attackers are capable of doing.

“For example, high-value targets tend to subject to advanced persistent threats, where the attack goal is usually cyber espionage, as opposed to causing disruptive damages. Attackers may exploit system vulnerabilities, conduct reconnaissance on the target, and covertly steal sensitive information over a long period of time. In addition, data loss posed by malicious insiders is also extremely prickly.”
