Moscow — In response to escalating cyber threats targeting telecommunications infrastructure, Russia has enacted new legislative amendments and is promoting advanced security solutions to safeguard its networks. The move comes amid growing concerns over cybercrime and the need to protect sensitive information transmitted via telephone and internet channels.
Legislative Actions and Cybercrime Focus
The Federal Law of April 4, 2025, “On the creation of the state information system of counteracting offenses committed using information and communication technologies, and on amendments to certain legislative acts of the Russian Federation,” signals a reinforced commitment to combating cyber abuses. These changes reflect the government’s understanding of the increasing sophistication and frequency of attacks targeting IP telephony and other communication channels.
IP Telephony: A Prime Target
fraudsters frequently target IP telephony networks with dual objectives: eavesdropping on conversations to steal commercial information and launching attacks for financial gain. Connection suppliers often detect these intrusions through a surge in suspicious activity,such as massive calls from corporate numbers to premium-rate lines.
Attack Methods and vulnerabilities
Cybercriminals often exploit vulnerabilities in corporate Private Branch Exchanges (PBXs) by guessing logins and passwords for SIP accounts. These attacks frequently occur during weekends when company activity is low and technical staff are less available. By routing calls through various corporate numbers, attackers can remain undetected long enough to profit from the fraudulent calls to premium numbers.
Session Border Controllers (SBCs) as a Key Defense
Companies employing anti-fraud mechanisms,such as traffic monitoring,automatic shutdown during abnormal activity,and password change protocols,are better positioned to defend against these attacks. A Session Border Controller (SBC) serves as a critical component in protecting corporate IP telephony. SBCs are increasingly deployed in sectors with high external intervention risks,including energy,industry,transport,and logistics.
How SBCs function
An SBC acts as a “border guard” between a corporate telephone network and the internet. Unlike a standard firewall, an SBC analyzes and rewrites SIP packets, effectively blocking attacks on a VOIP infrastructure.
Technical Features of SBC solutions
Information security (IB) solutions incorporating SBCs offer several security features:
- Fail2ban: Protects against brute-force password attacks by automatically blocking repeated login attempts.
- IPTables: Filters IP addresses, restricting access and preventing suspicious connections.
- Abnormal Activity Monitoring: Detects unusual usage patterns,such as a sudden spike in international calls,and can automatically shut down the PBX if thresholds are exceeded (e.g.,more than three simultaneous international calls).
- Two-Factor Authentication: Enforces an additional layer of security for administrator panel access.
Software vs. Hardware SBC Solutions
The Russian market offers two primary types of SBC solutions:
- Software-based: frequently enough based on platforms like KAMALIO, these solutions function as SIP-proxy servers in virtual environments and integrate with systems like Asterisk.
- Hardware-based: Dedicated devices like the Eltex SNG-3016 are used in scenarios with strict regulatory or infrastructure requirements.
import Substitution and Software SBCs
Software SBCs are particularly relevant in the context of import substitution, as they eliminate the need for specialized hardware and offer easier scalability. These solutions integrate directly into the telephone infrastructure and are based on open standards like Kamalio. While flexible and economical, they require a virtual machine.
Implementation considerations
Setting up SBCs, especially hardware-based solutions, requires specialized knowledge. Many organizations opt for suppliers that provide thorough implementation and operational support.
The Risk of Operating without an SBC
The optimal solution depends on an organization’s specific needs and existing security infrastructure. Though, operating a VOIP system without an SBC carries a significant risk of unauthorized access and potential compromise.

This law represents the government’s recognition of the growing sophistication and frequency of cyberattacks.
Why is IP Telephony a prime target for cyberattacks?
IP telephony systems are vulnerable to cyberattacks because they handle voice communication over the internet.Criminals target thes systems for two main reasons:
eavesdropping: To gain access to sensitive commercial information.
Financial Gain: To launch attacks and generate fraudulent calls.
What are the common attack methods used against IP telephony networks?
Cybercriminals often exploit vulnerabilities in corporate Private Branch Exchanges (PBXs).They commonly use these methods:
Guessing Logins and Passwords: Attackers try to guess SIP account credentials to gain unauthorized access.
Exploiting Weak Security: Attackers target systems with weak passwords or inadequate security measures.
Taking advantage of low activity: Attacks often occur during off-peak hours (weekends), when technical staff is less available.
What role do Session Border Controllers (SBCs) play in defending against these attacks?
Session Border Controllers (sbcs) are a critical security component for protecting corporate IP telephony. An SBC acts as a “border guard” between a corporate telephone network and the internet, analyzing and rewriting SIP packets to block attacks on the VoIP infrastructure. Companies employing anti-fraud measures like SBCs are better equipped to defend against cyber threats.
How do SBCs function to protect against cyberattacks?
SBCs are essential security components, working as a “border guard” between a corporate telephone network and the internet. They analyze and rewrite SIP packets to block attacks on VoIP infrastructure. Unlike standard firewalls, SBCs are specifically designed to handle SIP traffic, providing more granular control and protection.
What are the key technical features of SBC solutions?
Information security (IB) solutions incorporating SBCs offer the following security features:
