SMS Filtering configuration (Mobile Threat Defense policy for iOS)

The SMS Filtering configuration lets you define domain names for the SMS Filtering feature of Sophos Mobile Threat Defense.

SMS Filtering protects users from SMS and MMS attacks. It moves SMS messages containing a fake domain to SMS Junk, excluding messages from senders available in Contacts.

A fake domain looks like your real domain but is slightly modified:

  • Single characters are substituted, inserted, or transposed.
  • The domain name is amended by prefix or suffix.
  • The Top Level Domain (TLD) is different.

For example if the real domain is sophos.com, the following are fake domains:

  • s0phos.com (substitution)
  • soophos.com (insertion)
  • sohpos.com (transposition)
  • mysophos.com (prefix)
  • sophos.net (different TLD)

Subdomains like hr.sophos.com are not filtered.

If an SMS message is filtered, all further messages from the same sender are filtered as well.
