Unexpected Classification of 443 Traffic as "naver-line" with Subcategory "voip-video

Suhairul_Salleh — Wed, 04 Sep 2024 03:00:14 GMT

Hi everyone,

1) End user has confirmed that these users' computers do not have the LINE application installed. However, the 443 traffic is being identified as "naver-line," with a subcategory of "voip-video." Could you please help us understand the cause of this behavior?

2) And We noticed in the logs that certain activities are classified as the application "outlook-web-online." Could you please explain how this classification is defined? We want to understand if these activities could be related to Windows or Outlook, as we also have an Exchange Server, and the connected IP addresses are indeed from Microsoft.

Appreciate your help.
