| Description | ||||
| Malicious code protection mechanisms include, but are not limited to, antivirus and malware detection software. To minimize potential negative impact to the organization that can be caused by malicious code, it is imperative that malicious code is identified and eradicated. Tamper protection prevents malicious apps from turning off security features like virus and threat protection, behavior monitoring, cloud-delivered protection, etc., preventing unwanted changes to security solutions and essential functions. | ||||
