The VaxVoIP Server SDK Library DLL equips your SIP server with robust functionality to detect and prevent primary threats, enhancing the security of your VaxVoIP SDK-based SIP server.
VaxVoIP provides a comprehensive suite of methods to activate advanced threat detection mechanisms, including Scan SIP, Flood SIP, and Brute Force Attack detection. These methods are paired with event-driven features that enable real-time prevention of unauthorized activities, ensuring the integrity and security of your SIP server.
By leveraging these capabilities, your server can proactively identify and mitigate potential risks, such as malicious scanning, flooding attacks, and brute-force login attempts, maintaining reliable performance and safeguarding sensitive communications.
DETECTION AND PREVENTION OF SCAN SIP ATTACKS
The AttackDetectScanSIP() method strengthens the security of a VaxVoIP SDK-based SIP server by detecting and blocking unauthorized SIP traffic. It binds SIP requests to a specified domain and silently discards suspicious packets without sending any SIP response. The method also triggers the OnAttackDetectedScanSIP() event to notify the application of potential threats.
This approach minimizes engagement with attackers, reducing exposure to malicious activities such as port scanning and domain spoofing.
For comprehensive details about the exported events and methods, please refer to the Technical Manual and explore the provided sample source codes.
DETECTION AND PREVENTION OF FLOOD SIP ATTACKS
The AttackDetectFloodSIP() method activates a threshold for the rate of incoming SIP requests. When this threshold is exceeded, it detects a Flood SIP attack and triggers the OnAttackDetectedFloodSIP() event to alert the SIP server application.
This mechanism prevents attackers from overwhelming the service and causing downtime or performance degradation.
For detailed information about the exported events and methods, please refer to the Technical Manual and review the available sample source codes.
DETECTION AND PREVENTION OF BRUTE FORCE SIP ATTACKS
The AttackDetectBruteForceSIP() method monitors authorization failure attempts within a defined time interval. If the number of failed attempts exceeds the configured limit, it detects a brute force attack and triggers the OnAttackDetectedBruteForceSIP() event to notify the application.
This prevents attackers from continuously attempting random username and password combinations to gain unauthorized access.
