DNS Firewall

DNS Firewall : protect against DNS Malware

DNS Firewall proactively protects SOLIDserver™ appliances and Linux-based DNS infrastructures by detecting and blocking malware activity, identifying infected devices and preventing new attacks.

DNS Firewall offers easy-to-deploy and reliable malware protection that can be personalized to meet specific and granular requirements.

External DNS servers represent one of the most vulnerable entry points to enterprise networks and are therefore regularly targeted by hackers. DNS-based malware is particularly dangerous because it is often used to steal critical company and customer data.

EfficientIP’s DNS Firewall is a comprehensive DNS security solution that proactively prevents new attacks and protects SOLIDserver™ DNS appliances and/or Linux-based DNS infrastructures by detecting and blocking malware activity and identifying infected devices.

Ensure proactive and efficient protection against malware

The best way to protect your network infrastructure against malware is to eliminate the risk of device corruption. SOLIDserver™ DNS Firewall prevents connected devices from becoming infected with malware by enabling recursive DNS servers to block queries from clients that want to access domains and/or IPs known to be malicious.

Define DNS Response Policies

Recursive DNS server response policy (DNS RPZ) is based upon domain data feeds created manually by the IT administration team and/or provided by an external service. SOLIDserver™ DNS Firewall offers a granular approach to RPZ zone management. Instead of blocking an entire domain, exceptions for subdomains are created, and then for each individual subdomain response policies are defined. For example, redirection to a corporate warning page could be created. SOLIDserver™ DNS Firewall offers easy-to-deploy and reliable malware protection that can be personalized to meet specific and granular requirements.

Contain Malware Spreading and Identify Infected Devices

Based on DNS query analysis, SOLIDserver™ DNS Firewall detects and isolates clients infected with malware, blocking all communication with external websites and then disrupting malware activity. SOLIDserver™ DNS Firewall identifies the IP of the client responsible for the query.

Protect against DNS-Based Malware across the entire DNS infrastructure

SOLIDserver™ DNS Firewall provides a scalable, low cost and effective mechanism for blocking malware and phishing on a corporate network where no existing layer 7 filtering mechanism is not deployed. DNS Firewall policies can be automatically globally replicated across the entire DNS architecture, on selected servers, sites or SmartArchitectures, assuring overall consistency, decreased cost and improved global security.
