Safety Tips for Asterisk PBX

1) Do not accept SIP authentication requests from any IP address. Use the lines “permit =” and “deny =” sip.conf to only allow a reasonable subset of IP addresses to reach each user / extension listed in the sip.conf file. Even accepting incoming calls from “anywhere” (via [default]) should not allow those users reach authenticated elements.

2) Set the input value “alwaysauthreject = yes” in the sip.conf file. This option is available since version 1.2 of Asterisk, but the default value is “no”, which can be potentially unsafe. Setting this to “yes” orders failed authentication extensions using valid names with the same information from a rejection of nonexistent user will be rejected. This does not facilitate the task names attacker to detect existing extensions using techniques of “brute force”.
3) Use secure passwords for SIP entities. This is probably the most important safety measure. If ever you saw programs that generate and test key by brute force know that it takes more than words and numbers to a secure key. Use symbols, numbers, a mixture of uppercase and lowercase letters and at least 12 characters long.
4) Block ports Asterisk Manager Interface. Use “permit =” and “deny =” in manager.conf to limit incoming connections only known hosts. Again use secure key here too, at least 12 characters in a combination of numbers, letters and symbols.
5) Allow only one or two calls at a time by SIP entities when possible. Limit the unauthorized use of voip lines is a wise decision, this is also useful for the case that legitimate users make public their key and lose control of their use.
6) The SIP user names must be different than your extensions. Despite being convenient to have an extension “1234Z that maps to a SIP entry” 1234Z also SIP user “1234Z, this also facilitates the attackers to discover SIP authentication names. Instead use the MAC addresses off the device, or some combination of common phrases + extension MD5 hash (eg from the shell prompt, do “md5 -s ThePassword5000Z)
7) Ensure that the context [default] is safe. Do not allow unauthenticated callers reach contexts that allow them to call. Allow only a limited number of active calls go through the default context (use the “GROUP” as counter function). totally prohibit unauthenticated calls (if they so want) establishing “allowguest = no” in the [general] part of sip.conf.
