When implementing Intuity UC’s Direct Routing for Microsoft Teams, there are specific security considerations to keep in mind. Direct Routing allows Teams to connect to the Public Switched Telephone Network (PSTN) via a Session Border Controller (SBC) and an on-premises telephony system or third-party provider. Here’s a detailed look at how we secure Direct Routing in Teams:
Session Border Controller (SBC) Security
- SBC Selection: We deploy a SBC from a reputable vendor that supports Microsoft Teams and adheres to best practices for security.
- Configuration: We properly configure the SBC with security best practices, including using secure protocols and restricting access to known IP addresses.
- Firmware Updates: We regularly update the SBC firmware to protect against vulnerabilities and exploits.
Encryption
- TLS Encryption: Intuity UC offers Transport Layer Security (TLS) is used for signaling to protect communication between Teams and the SBC.
- SRTP Encryption: Intuity configures Secure Real-time Transport Protocol (SRTP) should be used to encrypt media streams (voice) to prevent eavesdropping.
Network Security
- Firewall Rules: We configure firewalls to allow only necessary traffic to and from the SBC, and we restrict access to known and trusted IP addresses.
- Network Segmentation: We place the SBC in a dedicated network segment to isolate it from other parts of your network and minimize potential attack vectors.
Access Control
- Authentication: Intuity UC implements strong authentication mechanisms for accessing the SBC and related systems. Use multi-factor authentication (MFA) where possible.
- Authorization: Intuity UC implements role-based access control (RBAC) to ensure that only authorized personnel can make changes to the SBC configuration or access sensitive information.
Monitoring and Logging
- Activity Monitoring: At Intuity UC, we continuously monitor traffic and logs for any unusual or unauthorized activity. Use security information and event management (SIEM) systems to correlate and analyze log data.
- Alerts: We set up alerts for critical events or anomalies in SBC traffic and Teams usage.
Compliance and Configuration
- Compliance: Intuity UC ensures that your Direct Routing setup complies with relevant regulations and industry standards (e.g., GDPR, HIPAA).
- Configuration Management: We regularly review and update configurations to adhere to security best practices and to address any vulnerabilities.
Endpoint Security
- Secure Endpoints: Intuity UC ensures that user devices accessing Teams are protected with up-to-date antivirus software, firewalls, and security patches.
- Data Protection: We implement policies to protect data on endpoints and ensure secure storage and transmission of sensitive information.
Redundancy and Failover
- High Availability: Configure redundancy and failover mechanisms for your SBC to ensure service continuity and resilience against potential failures or attacks.
Regular Audits and Assessments
- Security Audits: Intuity UC conducts regular security audits and assessments to identify and address any vulnerabilities or weaknesses in your Direct Routing setup.
- Penetration Testing: We regularly perform penetration testing to evaluate the security of your SBC and related infrastructure.
