## Disables unneeded network protocols that will likely not be used as these may have unknown vulnerabilties.
## Credit to Tails (https://tails.boum.org/blueprint/blacklist_modules/) for some of these.
## > Debian ships a long list of modules for wide support of devices, filesystems, protocols. Some of these modules have a pretty bad security track record, and some of those are simply not used by most of our users.
## > Other distributions like Ubuntu[1] and Fedora[2] already ship a blacklist for various network protocols which aren't much in use by users and have a poor security track record.
