[asterisk-users] Sip Registration Hijacking

[eherr]

Can you please elaborate on rate limiting. Not how to implement it but rather how implementation is beneficiary.

 

Reading up on it, it appears that it just checks the tcp connections and denys connection if limit is passed.

 

In my thoughts, this is essentially a live fail2ban monitor in respects to attempted authentications. 

 

Thanks,

Rate limiting (google) via iptables FTW! Good luck!
