Too few security systems interoperate, which makes it difficult for organizations to block or detect data breaches. But Cisco has an interoperability plan to improve the state of cybersecurity defenses, Chief Security Architect Martin Roesch says.
To help organizations discover what they don't know is happening on their networks, Darktrace uses machine learning to create advanced baselines of normal behavior, then sounding alarms when it sees deviations.
To better secure enterprise networks, as well as detect and respond more rapidly to data breaches, businesses need to know the who, what, where, when and why of all endpoints that connect to network resoruces, says ForeScout's Sandeep Kumar.
