Toll Fraud Threats
• The telecom industry incurred annual losses of $46.3 billion due to toll fraud.*
• On average, an unprotected IP-PBX on the Internet will be hacked within 30 minutes.
• A few hours of unauthorized access can easily cost the price of an entire phone system -- many times over!
* According to the Global Fraud Loss Survey 2013 of the …Communications Fraud Control Association (CFCA).

Defense #2: Built-in Firewall
• Most vulnerable cyber-attack point is where the “untrusted” and “trusted” networks meet
• CompletePBX must be installed on a LAN protected by a firewall/NAT router
• CompletePBX also has its own built-in firewall
• Default rules can be modified to accommodate specific applications relevant to customer’s business

Defense #3: Initially Locked
• CompletePBX is preconfigured to use restrictive security policies:
• In the default configuration SIP calls from endpoints not located on the LAN are rejected
• CompleteSBC firewall configuration must be modified to allow receipt of inbound calls from Internet sources

Defense #4: Password Strength
• Set strong passwords for SIP/IAX2 extensions, DISA, and call-back functions
• Define passwords for all int’l outbound routes
• Built-in algorithm detects weak passwords and issues a warning
