Network Security
Network zones are stacked with increasing proximity to the open internet or DMZ. Each zone is traversed by ingress and egress points through an application or server, with appropriate authentication and authorization for connecting system traffic.
TRA Security
This section describes the general security configuration requirements for Traffic Routing Agent (TRA). These security requirements apply when virtual servers are defined and specified as secured.

- About MATRIXX Security
- Introduction to MATRIXX Cloud Native Security
  The information in MATRIXX Security is best-practice information and identifies MATRIXX-specific security considerations and implementations. For container-specific and Kubernetes security information, see the third-party documentation.
- Cloud Native Security
  The information here addresses cloud native security and includes recommendations for securing your cloud native implementation.
- Managing Certificates
  MATRIXX uses certificates signed by a trusted certificate authority, or validated by other means, to establish secure communications with another party with the corresponding private key.
- Enabling Transport Layer Security
  Transport Layer Security (TLS) provides secure internet connections by encrypting data sent between a browser, a website, and the website server to ensure that data is transmitted privately.
- Network Security
  Network zones are stacked with increasing proximity to the open internet or DMZ. Each zone is traversed by ingress and egress points through an application or server, with appropriate authentication and authorization for connecting system traffic.
  - MATRIXX Gateway Proxy
    MATRIXX includes Gateway Proxy that acts as a secure entry point for all network traffic that is not the result of subscriber usage. It sits between external applications and the Traffic Routing Agent (TRA).
  - RS Gateway Security
    RS Gateway uses Spring Security to authenticate clients using login ID and password credentials.
  - Business API Gateway Security
    The Business API Gateway is a development framework that includes the Business API SDK, Rest Services Gateway (RS Gateway), Gateway Proxy, and application tier. It allows custom mobile applications, Web clients, and other custom implementations to integrate with MATRIXX.
  - SBA Gateway Security
    SBA Gateway supports TLS Mutual Authentication.
  - TMF Gateway Security
    TMF Gateway supports HTTP authentication through a configurable authorization URL.
  - TRA Security
    This section describes the general security configuration requirements for Traffic Routing Agent (TRA). These security requirements apply when virtual servers are defined and specified as secured.
    - TRA Virtual Server TLS Configuration
      Specify virtual server (VS) configuration options for Transport Layer Security (TLS) to define communication between the Traffic Routing Agent(TRA) and an upstream Diameter client using the TLS protocol. The supported protocol versions are TLSv1.3 and TLSv1.2.
    - TRA Pool Node TLS Configuration
      Specify pool node configuration options for Transport Layer Security (TLS), previously known as Secure Sockets Layer (SSL), to define communication between the TRA and a downstream pool node using the TLS protocol. The supported protocol versions are SSLv2, SSLv3, TLSv1, TLSv1.1, and TLSv1.2.
  - Self-Signed Certificate Detection and Handling
    While self-signed certificates can be used in controlled environments such as internal testing, because they are not verified by a trusted certificate authority (CA) they must not be used in production environments. If the use of a self-signed certificate is intentional, such as for testing purposes, the MDC Gateway and Traffic Routing Agent (TRA) components include ways to override default handling.
  - Network Security Checklist
    The following is a list of best practices for network design and configuration.
- Application Security
  Application security includes configuring web applications and gateways.
- Database Security
  Depending on your MATRIXX environment, you can use multiple external databases.
- OAuth 2.0 Identity and Access Management
  MATRIXX supports third-party identity and access management application integration.

Glossary

TRA Security

This section describes the general security configuration requirements for Traffic Routing Agent (TRA). These security requirements apply when virtual servers are defined and specified as secured.

The TRA requires a user-created Privacy Enhanced Mail (PEM)-formatted certificate and private key pair placed in /opt/tra/custom/tra_certificate to communicate with secured clients. That default directory can be changed using the TRA configuration attribute security-own-certificate-path.

The TRA requires trusted certificates to authenticate client connections placed in /opt/tra/custom/trusted_certificates/. That default directory can be changed using the TRA configuration attribute security-trusted-certificates-path.

Important: Apply appropriate access protection to all keys and certificates.

Secured Connection Setup Errors

In the event of a secured transport setup error, the TRA generates error-level messages with diagnostic information, and an SNMP trap tfcSslErrorDetails (object ID: 1.3.6.1.4.1.35838.1.2.1.2.15.2) to alert you to potential threats or configuration problems. The SNMP trap carries string-based diagnostic data that includes the client address and other error information.

For more information about SNMP statistics, see the discussion about MATRIXX Engine SNMP Statistics in MATRIXX Monitoring and Logging.
