Finding ID Version Rule ID IA Controls Severity
V-6289 DTBI112 SV-45326r1_rule DCMC-1 Medium
Description
ActiveX controls can contain potentially malicious code and must only be allowed to be downloaded from trusted sites. Signed code is better than unsigned code in that it may be easier to determine its author, but it is still potentially harmful, especially when coming from an untrusted zone.
