SBC controls

Our SBCs secure the mobile subscriber access border and the interconnect/peering border. They protect themselves and other elements of the service delivery infrastructure from malicious denial-of-service (DoS/DDoS) attacks and non-malicious overloads, and they protect mobile subscriber endpoints and privacy.

SBC DoS/DDoS protection

  • Protect SBC from DoS/DDoS attack and other malicious attacks
  • Protect SBC from non-malicious overloads
  • Allow trusted/authenticated users access while under DoS attack
  • Dynamically accept or reject traffic based on device behavior

Access control

  • Filter specific devices or whole networks on a per-application basis
  • Permit access to known devices or networks
  • Permit access to authorized/registered users; permit or deny access to mask users
  • Dynamically accept or reject traffic based on device behavior
  • Accept media only for authorized sessions

Topology hiding & privacy

  • Hide core topology to prevent directed attacks and preserve confidentiality
  • Mask user information for privacy and confidentiality
  • Protect users and service provider infrastructure from eavesdroppers, identity thieves and fraud
  • Secure L2 and L3 VPN customers by maintaining security isolation between VPNs
  • Support inter-VPN sessions; monitor media for intra-VPN sessions for lawful intercept or fraud prevention

Virus, worm & SPIT protection

  • Protect network from malicious attachments, prevent malformed messages from overloading resources
  • Restrict usage to prevent automated dialing/unwanted sessions

Service infrastructure DoS prevention

  • Prevent DoS attacks from reaching core service infrastructure
  • Protect core from signaling overload attacks by enforcing call rate limiting, message rate limiting and code gapping policies

Fraud prevention

  • Perform signaling and media validation by authenticating and authorizing users
  • Enforce service contract per-user/device and prevent piggyback usage

Monitoring and reporting

  • Monitor and report on alarms for attacks and overloads
  • Audit trails for attack response & fraud investigation
  • Provide secure monitoring & management access to protect from unauthorized personnel
