Protect Healthcare Data from Phishing
The Threat of Phishing Attacks on the Healthcare Industry One of the key areas of online security that every HIPAA-covered entity should make its priority is to protect healthcare data from phishing. Phishing attacks are becoming a greater threat to the healthcare industry than any other attack vector.
