In today’s digital world, securing IP-based voice communications has become a serious concern for organizations. Due to their internet-based nature, VoIP networks are constantly exposed to various cyber threats. However, having a Session Border Controller (SBC) can serve as a critical safeguard in securing these vital infrastructures.
Common Threats in VoIP Networks
VoIP networks—especially those using protocols such as SIP—are more vulnerable than traditional telephony systems. Key threats include:
- DoS/DDoS Attacks: These attacks flood the server with heavy traffic to disrupt services, potentially leading to call drops or complete service outages.
- SIP Flooding: A high volume of fake SIP requests is sent to the server to exhaust its processing resources.
- SIP Spoofing: Attackers impersonate legitimate users to initiate fraudulent calls or access sensitive information.
- Man-in-the-Middle (MitM) Attacks: A third party intercepts or alters the data being transferred without the knowledge of the call participants.
The Critical Role of SBC in Enhancing VoIP Security
Chakavak SBC, with its locally developed design and advanced encryption and traffic control technologies, offers a comprehensive solution for addressing security threats in VoIP environments. Its key advantages include:
1- Intelligent Defense Against DoS/DDoS Attacks
By analyzing incoming traffic and detecting malicious patterns, Chakavak SBC prevents large-scale attacks from penetrating and disrupting call services.
2- Filtering SIP Flooding Attacks
The system’s advanced algorithms can identify and block fake SIP requests, ensuring that only legitimate traffic reaches the server.
3- Preventing Identity Spoofing
Support for mutual encryption protocols such as TLS, SRTP, and DTLS ensures security at both signaling and media levels, preventing unauthorized access to the network.
4- Encrypted Communications to Prevent MitM
All calls are conducted using secure encryption standards to protect against eavesdropping or data alteration during transmission.
5- Access Control and Targeted Routing
Chakavak SBC enables the implementation of precise policies for managing calls, enhancing not only security but also call quality.
6- Quality of Service (QoS) Assurance
With QoS support and intelligent traffic management, the system maintains high audio quality in calls while preventing delays or unwanted disconnections.
Why a Locally Developed SBC Is Essential in Iran?
Considering the specific conditions of the country’s cyberspace, international threats, and technical restrictions caused by sanctions, adopting a locally developed SBC like Chakavak is a smart and essential choice for organizations. With capabilities such as network topology hiding and advanced encryption, it meets national-level security requirements.
Conclusion
True security in VoIP networks cannot be achieved without an effective SBC. With modern technologies, local design, and reliable performance, Chakavak SBC not only protects your communication infrastructure against threats but also elevates the user experience to an optimal level. If you are seeking a secure, flexible, and scalable solution for managing VoIP communications, Chakavak SBC is a dependable choice.
