Today’s networks are vulnerable to excessive attacks. The principles of zero trust are the gold standard organizations use to protect apps and data. A key element of zero trust access is “trust no one, authenticate everyone”.
It is virtually impossible to predict ransomware attacks. Malicious actors use security holes in corporate IT networks to find vulnerable devices, gain unauthorized access to them, and then use this access to spread malware and ransomware to other devices on the network.
