Description
When a Jamf Pro EMM server accepts an unverified certificate, it may be trusting a malicious actor. For example, messages signed with an invalid certificate may contain links to malware, which could lead to the installation or distribution of that malware on DoD information systems, leading to compromise of DoD sensitive information and other attacks.
