The media was buzzing with word that the US Army has banned the use of the video sharing app TikTok over security concerns. https://www.military.com/daily-news/2019/12/30/army-follows-pentagon-guidance-bans-chinese-owned-tiktok-app.html

A quick check of the Cisco Firepower Application Detector Reference (aka VDB) database shows that the system can natively detect the application, so blocking it is straightforward.
