Threats you should be aware of

“One of the biggest threats is the administrative threat, caused by vulnerabilities related to having a super user or super password that can access every file,” he says. “Industry and government are moving away from super users due to leaks that have occurred. If that super user or super password is compromised embedded computer, every piece of data in a system is vulnerable. At SafeNet we assume someone is bound to get in, so we work at encrypting each object so even when they get in they can’t wreak havoc with the data. The more granular you drive the encryption, the less exposure your data will have to malicious attacks.”
