Nokia Networks, last week has extended its security portfolio with two new security solutions - Network Access Guard and Signaling Security Solution - with the aim to help shield network operations from unauthorized access, both from external attackers and from staff within organizations.
The Network Access Guard solution is designed to provide identity access management to secure traditional, virtualized and Software Defined Networks in multivendor environments. Protection is achieved through a combination of single sign-on authentication for user simplicity, session management to control who accesses network resources, audit logging to track user sessions, and user policy management.
As for the Signaling Security Solution, consisting of Signaling Guard and Security Assessment service, it can identify weaknesses in an operator's SS7 infrastructure and implement a firewall to protect against subscriber data being hacked as well as other malicious intrusions.
According to Nokia Networks, as the complexity of mobile network security increases with 3G/LTE and telco cloud/SDN, a centralized identity and access control system that is able to authenticate operator staff and provide secure, granular access to network elements is required. Potential vulnerabilities in the SS7 (Signaling System 7) protocol could open the door to advanced fraud, hijacking of subscriber communications or Denial-of-Service attacks, added Nokia Networks.
