Table 13: Influence of _Bark_ on STRIDE impacts for \(S_{\gamma}\). Rating the possible improvement through the usage of filtering: no/only low (grey), some (red), medium (yellow) and high (green). Another point where _Bark_ is superior is in the case of protecting the _Private Smart Home Device_ from being accessed by the guest (_GAP_), where a _high_ influence was found.
