3. Click Search.
4. In the
security policy log, check whether the action is Block.
If the action is Block, the traffic is blocked by the security policy.
In this case, you should check the
security policy to determine whether the traffic matches the correct security
− If the correct security policy is
matched, the traffic should be blocked and no action is required.
− If the correct security policy is not
matched, choose Policy > Security Policy > Security Policy to adjust the sequence
or parameters of the security policy.
If the action is Allow, the traffic is blocked by the content security function, not
by the security policy. In this case, go to cause 2.

content security function.

application behavior control: Choose Monitor > Log > Content Log.
3. On the
corresponding log page, click Advanced
Search in the upper right corner and enter the name of the security policy.
4. View the
application and action in the displayed logs.
If the application is the video

security profile is correctly configured. For detailed configurations, see the
description of the related profile.
