DNS FirewallProtect Users and Block DNS-Based Malware Activity

Hackers and Malware Abuse DNS Services to Circumvent Traditional Security Systems

DNS-based malware is particularly dangerous because it is often used to steal critical
company and customer data, interrupt business continuity and damage brand reputation. Hackers take advantage of the underestimation of DNS services’ key role in the cyber kill chain – 91% of malware are using DNS services to build attacks. A global 2019 DNS Security survey conducted by IDC revealed that 82% of respondents said they had been targeted by a DNS attack in the last 12 months. Traditional security systems are not enough to mitigate this type of threat, as they could be easily circumvented.

DNS Firewall is embedded in EfficientIP SOLIDserver appliances. The product provides a purpose-built and complementary solution to traditional enterprise network security systems, to effectively protect against DNS-based malware and advanced persistent threats (APT). It’s enhanced DNS query filtering capabilities, combined with dynamic threat intelligence feeds, allow for the quick identification of suspicious device activity, preventing malware infection and spread within a network, as well as phishing campaigns and data exfiltration attempts.

Icon DNS Firewall

Prevent Infection and Block DNS-Malware Activity

The SOLIDserver™ DNS Firewall solution, based on RPZ (Response Policy Zone), offers a dedicated layer of defense for malware protection and mitigation. DNS Firewall prevents connected devices from becoming infected with malware and blocks their activity by enabling recursive DNS servers to stop or redirect queries from clients that want to access identified malicious domains and/or IPs. Illegitimate communications with C&Cs/botnets, and DNS based data exfiltration (DNS tunneling) are immediately blocked, before they impact and damage your company.

DNS_Firewall-Threat Intelligence DataFeed

Adapt Malware Protection With Threat Intelligence

To keep pace with the ever-evolving threat landscape, DNS Firewall includes dynamic threat intelligence services. DNS Firewall comes with this kind of constantly updated data feed built from various distributed sources, to combat categories such as:

  • Abuse and spam related domains
  • Phishing-related domains
  • Malware-related domains
  • Cracked website FQDN(s)
  • Botnet Command and Control

The data feed can be easily customized with specific filtering policies to adapt to local security requirements.

Using DNS Guardian, internal threat intelligence can be developed, bringing capability to detect zero-day malicious domains.

Unified Security Policies_v2

Get Unified Control of DNS Filtering Policies

The SOLIDserver appliance brings advanced filtering policy management capability, ensuring an up to date list of malicious or forbidden IP addresses, domains, URLs, or name servers. The entire DNS Firewall architecture is automatically updated regardless of the server type (Linux or EfficientIP’s secure DNS appliance) protecting – in a single operation – your organization from malware attacks.

Infected Device Identification

Enhance Malware Mitigation and Remediation with Infected Device Identification

Leverage DDI and discovered network’s data and locate infected devices with technical, organizational and contextual information (site, floor, IP address, name etc.) for improved threat remediation and security response. Track over time historical compromised device localizations to spot lateral movement of malware and block their activity.

Reports

Benefit From Advanced DNS Threat Reporting

SOLIDserver™ pre-defined or customized reports give consolidated visibility and data-driven insights on DNS services for network security teams. In addition, SOLIDserver delivers high-performing logging capabilities which can be seamlessly integrated with leading SIEM solutions such as Kibana, Splunk and QRadar. This integration provides DNS data for log correlation, enabling centralized analysis and reporting, including immediate access to requested malicious domains.
