Metropark highly recommends a state-of-the-art firewall to protect your network. Metropark sells Peplink firewalls which can play a crucial role in securing your network, especially in environments where Voice over Internet Protocol (VoIP) communications are critical. Here are several ways Peplink firewalls can enhance network security to protect VoIP systems:
Traffic Filtering and Inspection
Peplink firewalls from Metropark can inspect network traffic, including VoIP packets, to detect and block malicious or unauthorized activities. By implementing rules and policies, the firewall can filter traffic based on source, destination, protocol, and other parameters, ensuring that only legitimate VoIP traffic is allowed through.
Intrusion Prevention System (IPS)
Peplink firewalls from Metropark often include intrusion prevention features that monitor network traffic for suspicious patterns or known attack signatures. This helps prevent unauthorized access attempts, DoS (Denial of Service) attacks, and other threats that could disrupt VoIP services or compromise network security.
VPN Support for Secure Communications
Virtual Private Networks (VPNs) create encrypted tunnels for secure communication over public networks. Peplink firewalls from Metropark support VPN technologies, allowing VoIP traffic to be securely transmitted between remote offices, telecommuters, or mobile devices. This helps protect VoIP data from interception or eavesdropping.
Quality of Service (QoS) Management
VoIP communications require consistent and reliable network performance to ensure high call quality and minimize latency. Peplink firewalls from Metropark can prioritize VoIP traffic using QoS settings, ensuring that voice packets receive preferential treatment over other types of traffic. This prioritization helps maintain voice call clarity and reliability, even during periods of network congestion.
Stateful Packet Inspection (SPI)
Peplink firewalls from Metropark employ stateful packet inspection to track the state of active network connections. This helps in detecting and blocking unauthorized VoIP connection attempts or anomalous behavior that could indicate a security threat, such as SIP (Session Initiation Protocol) attacks or call hijacking attempts.
Access Control and Authentication
Peplink firewalls from Metropark offer robust access control mechanisms, allowing administrators to define user roles, access policies, and authentication methods. By enforcing strong authentication for VoIP devices and users, the firewall ensures that only authorized personnel can access VoIP systems and services, reducing the risk of unauthorized access or VoIP-related security breaches.
Regular Updates and Patch Management
Peplink regularly releases firmware updates and security patches to address vulnerabilities and enhance firewall capabilities. Keeping the firewall firmware up-to-date ensures that the network remains protected against emerging threats and exploits targeting VoIP systems and infrastructure.
By leveraging these security features and best practices, Peplink firewalls from Metropark can effectively secure networks hosting VoIP communications, mitigating risks such as eavesdropping, unauthorized access, service disruptions, and data breaches that could jeopardize the integrity and reliability of VoIP services.
