The Voice Security Company Kirk Vaughan Product Director –VoIP SIP Application Security

VoIP security is a big deal Why? Fear of the Unknown Everyone talks about VoIP security threats DoS Attacks Eavesdropping Theft-of-service These are the obvious ones! And they are manageable. Theft-of-identity

What is scary is what is around the corner that we can’t see Hacker’s hate Billy Gates….will John Chambers be next? Disgruntled employees can wreak havoc with internal access IT security “Best Practices” Stay off of Billy’s platforms Secure Backdoors Enterprises are easy targets – too little voice security Some current VoIP Security Recommendations help Strict Authentication

Enterprises are not early adopters Business case is necessary Proven reliability and security ROI calculation includes cost of management Build applications with this in mind from day one Data Networking History taught us  Network security requires lots of tools – not one single answer - Firewalls - IPS/IDS - Anti-viral software  Modem and fax lines create a huge security backdoor - Some enterprises have hundreds which are unmonitored thus creating an insecure voice and data network!

The backdoor modem is the Data Security Manager’s “Achilles Heel” My message to the SIP Application Development world…. Don’t become the Achilles Heel to the VoIP world

Before you write 1 line of code, ask how the operations manager will.. - Have Visibility and Control of user behavior on your service - Simply and effectively manage the service Configuration of applications User database Security policy - Authorize use of approved applications (hopefully yours!) - Accurately account and report on performance, usage and charging - Guarantee the security of the application Are you in the business of writing applications for enterprise users?

Integrated voice service platforms (MS RTC Server - Greenwich) SIP-enabled web applications Embedded services via API Don’t be naïve – enterprises won’t allow new communication services into their networks without appropriate management, visibility and security Enterprise use of Public IM services (MS Messenger, AIM, Yahoo) Created market for IM gateways Access to SIP services over the internet (VONAGE, FWD) Application Layer Gateways and VoIP-aware Firewalls

VoIP Security Manager secures the data and voice network external threats over the internet or WAN TDM Security (Telecom Firewall) secures the data and voice network external threats over unmonitored analog modem and fax lines internal threats from trusted or unknown sources Both devices provide management, reporting, and security policy tools No need for two separate management and security tools… Combine them!!

The Real-Time Mixed Media Firewall - Provides real-time Visibility and Control of user behavior - Combines the security and monitoring features of several platforms Application-Layer Gateway Telecom Firewall Call-Accounting System IM Gateway Client Registrar (DHCP) Presence Manager Security policy manager with reporting Bandwidth and routing policy manager - Manages access to both on-net and off-net VoIP services Simplifies the management of mixed media application platforms and secures the entire network!!! - Secures TDM Voice Network against attack and misuse

The Real-Time Mixed Media Firewall - Aids in the management and provisioning of SIP Services Secures backdoor modem threats Restricts use of unapproved rogue clients and applications Prevents hacker attacks by controlling content across network borders Detects signaling anomalies and IPS signatures relating to VoIP Single User database simplifies management of user profiles Single GUI interface for setting up policies, reporting, and permissions Graphical depiction of application/network usage stats in real-time Application layer security - Secures mixed media VoIP and TDM network resources

 We have to secure both networks while we migrate  Security and Management of applications is key  Enterprises are suspicious of what they can’t control  They have been burned by the back-door modems  Can they be certain that you aren’t the next back-door?  Design apps for use with a CPE-based RTMM firewall  Even the great “killer app” needs security

Thank you!!!
