  1. SIP, UC, and Security Joel Maloff Phone.com jmaloff@phone.com February, 2012

  2. Setting the Stage for Security • SIP is a protocol incorporated into various service offerings. • Unified Communications is a concept that incorporates various communications functions into a single approach. • Ensuring the security of our communications, especially given the proliferation of the cloud, is more important than ever!

  3. Security is STILL an Issue – Even for the Big Guys! • ESG (Enterprise Strategy Group) Research surveyed large enterprises (2011) and found the following: • 20% are certain that they have been the target of an Advanced Persistent Threat (APT); 39% believe that they have likely been targeted. • Unfortunately, many of these felt inadequately prepared to respond!

  4. Security is STILL an Issue – Even for the Big Guys! • 32% - lack of security forensic skills• 29% - lack of technical skills in incident response team• 26% - inadequate ability to gather relevant information • 26% - lack of executive management buy-in to incident response policies and procedures• 25% - lack of integration between the incident response and legal team• 23% - lack of a formal external communication plan• 23% - lack of a formal internal communication plan • If companies of 1000+ employees have these issues, where does that leave the smaller organizations? • Source: http://www.networkworld.com/community/blog/2012-year-incident-response

  5. Some of the Challenges • Unified Communications is more than just voice. • Document exchange • Archival and auditing for compliance with regulatory and legal statutes • Platform-specific attacks

  6. Some of the Challenges • Eavesdropping on VoIP, IM • Hacking IP or soft phones to remotely activate them as an eavesdropping attack vector • Toll Fraud • Denial of Service Attacks

  7. Addressing the Challenges • SIP and UC are part of the business information infrastructure. • They must be incorporated into the existing information systems security policies and procedures. • Documented policies and procedures with regular review are essential for minimizing the impact of security vulnerabilities. • Vendors and service providers can help, but they are not responsible for your security plan – you are!

  8. Addressing the Challenges • IP phones are NOT phones as in the past – they are network-enabled computers and must be treated as such! • Firewalls, SBCs, ACLs, VLANs, authentication, encryption, and IDS/IPS are all tools that are to be deployed as part of a coherent PLAN – they are not themselves strategies or policies! • Security requires perpetual vigilance • Penetration testing is invaluable.

  9. Let’s hear from our panel!
