Telecom Security

  1. Mobile Network Security:

 We provide professional level security solutions plus consulting services to Mobile Operators to meet up their unique needs. Mobile Operators also look at means to monetize their investment in security by developing additional methods of revenue trying to get a supplement in ARPU. As mobile smart-phones flourish and with data being easily reached from anywhere, at any time or device; Mobile Operators want to make sure themselves from their own mobile users with attacks start off from the Internet.  We provide comprehensive security solutions as well as consulting services every Mobile Network Operator environment.

  1. LTE /4G Security Architecture:

Service Architecture Evolution (SAE) & Long-Term Evolution (LTE) give collective IP-based flat core architecture and speedy 100Mbps data rates in excess of the radio networks re-defining the manner mobile data is used. With mobile data networks evolving from EDGE / GPRS / UMTS / HSUPA & HSDPA networks; LTE assures to set the mobile data schema for the next decade even as praising existing 3GPP & non-3GPP standard (WiMAX) based networks. 3GPP have uniformed on LTE Security Architecture through many releases and is focused on the following TS standards;

  • TS 33.401 – SAE Security Architecture
  • TS 33.210 and 33.310 – Network Domain Control Plane Protection & Backhaul Security
  • TS 33.203 – IMS (IP Multimedia Subsystem) Security

Our Solution has in-detail knowledge on SAE / LTE security architectures & standards

  • UMTS / 3G Security Architecture:

UMTS or 3G has evolved, since it’s opening into mainstream mobile operators. With early claimed mobile data rates of 384kbps, evolving into HSDPA-HSUPA as 3.5G -3.75G respectively providing as much as 24Mbps. UMTS/3GPP standards have been exclusive of infrastructure and core security needs in mind. Though the radio access security has been inherited & made in rather well the network domain has fairly lacked in security oversight. Our Solution has comprehensive Mobile Network Security knowledge and can help mobile operators to decrease risk factors from a very challenging environment.

  1. SCTP / Signaling Security:

RFC 5062 obviously highlights the security issues for SCTP protocol that is mainly used for signaling functions in the Mobile Operator setting. SCTP protocol is neither TCP nor UDP and is based on a multi-homed transport protocol on a four-way handshake. Any attack on the signaling infrastructure of the Mobile Core Network can prevent the mobile users from voice & data calls. With such vital importance of the signaling plus control plane, SCTP usage needs to be secured to make sure stability in services for the mobile operator. The SCTP security solution is based on the following features;

  • SCTP association knowledge for session setup & close
  • Multi-homing understanding – multiple IP’s per single association
  • Rate limiting for SCCP/SST/SSP messages
  • SCTP application message understanding – M3UA/SCCP & others
  • SCTP ALG for operator inter-connect to provide for NAT needs
