Netscout Launches Adaptive DDoS Protection for Arbor Edge Defense

Netscout Systems has launched Adaptive DDoS Protection for Arbor Edge Defense (AED) to protect ISPs and enterprises from DNS water torture attacks. According to the Netscout DDoS Threat Intelligence Report, Domain Name System (DNS) water torture attacks increased 353% in the first six months of 2023, overwhelming Authoritative DNS server resources and bringing down critical DNS services.

“DNS water torture DDoS attacks have been around since 1997, yet many organizations still struggle to efficiently identify and mitigate them,” said John Grady, principal at Enterprise Strategy Group. “These attacks send invalid requests to an Authoritative DNS server to slow it down and prevent legitimate requests from getting a response. Security teams cannot broadly block this traffic without potentially impacting valid requests due to the pervasiveness of DNS and can easily misdiagnose an attack as a performance issue. Netscout’s Adaptive DDoS Protection auto-learns and adapts to changes in DNS server configuration, enabling AED to identify and mitigate these attacks.”
DNS water torture is one of many attack techniques adversaries can adopt to bring down DNS infrastructure. Netscout’s Adaptive DDoS Protection for AED protects against many DDoS attack techniques at scale by:
- Auto-learning legitimate hostnames for each domain by continually analyzing DNS query and response packets
- Adapting to DNS server configuration changes to prevent blocking legitimate domains and changes to attack techniques
- Intelligently blocking DNS water torture IP sources on a query-by-query basis
Adaptive DDoS Protection gives SOC teams a scalable, always-on, stateless packet processing solution that uses unmatched visibility into more than 50% of all internet traffic, real-time global DDoS attack threat intelligence, and decades of DDoS mitigation experience to automatically detect, adapt to, and mitigate dynamic DDoS attacks. “Adaptive DDoS Protection for AED provides customers with a unique hybrid multi-layer DDoS defence architecture,” said Scott Iekel-Johnson, AVP, DDoS and Threat Intelligence at Nertscout. “It can learn and filter millions of legitimate hostnames and thousands of domains backed by our ATLAS Intelligence Feed (AIF) to thwart modern-day attacks and advanced threats.”

Sophos Boosts Firewall with New Protection and Incident Response Features

Sophos has announced a significant update to its Sophos Firewall software, introducing enhanced protection and incident response capabilities. This update notably includes Sophos NDR Essential, a new feature now available free of charge to all customers holding an XStream Protection license for Sophos Firewall.
This integration empowers Sophos Firewall with two dedicated artificial intelligence (AI) engines specifically designed to detect both malware communications and those utilizing algorithmically generated domain names. This advanced functionality, derived from the Sophos Network Detection and Response (NDR) probe, aims to identify sophisticated malware communications even if they are previously unknown or not yet indexed. It serves as a powerful complement to the Active Threat Response capabilities already embedded within Sophos firewalls.

Chris McCormack, Senior Product Marketing Manager at Sophos
Addressing the technical demands of such advanced detection, Chris McCormack, Senior Product Marketing Manager at Sophos, explained the strategic approach, “NDR traffic analysis requires substantial processing power. That’s why we’ve adopted a new approach by deploying an NDR solution in Sophos Cloud to offload the heaviest tasks from the firewall.” This cloud-centric design ensures optimal performance without burdening the firewall’s on-device resources.
Beyond network detection, the update also brings significant improvements to connectivity and user authentication. Sophos Connect now integrates EntraID for Single Sign-On (SSO). This new feature for the VPN client, bundled with Sophos Firewall, is set to enhance both the security and user experience for SSL and IPsec VPN connections. The integration with EntraID (Azure AD) enables users to authenticate and leverage multi-factor authentication for both Sophos Connect and access to the user portal hosted by the firewall, streamlining secure access.
Further VPN-related enhancements include:
- Improved user interface and usability: Connection types have been renamed for greater clarity, with “site-to-site” now referred to as “policy-based” and tunnel interfaces as “route-based,” making configurations more intuitive.
- Dynamic validation of the IP address pool: For VPN connections (SSL VPN, IPsec, L2TP, and PPTP), the system now dynamically validates the allocated IP address pool, helping to better resolve potential IP address conflicts.
- Strict profile enforcement: IPsec profiles now exclude default values to ensure algorithm synchronization, effectively eliminating potential fragmentation of session negotiation packets that could otherwise prevent site-to-site VPN tunnels from being established.
- Route-based VPN and SD-RED scalability: The system has been optimized to support up to 3,000 simultaneously established tunnels. Specifically, Sophos Firewall solutions can now manage up to 1,000 SD-RED site-to-site tunnels and connect up to 650 concurrent SD-RED devices.
Additional management improvements enhance administrative flexibility and search capabilities:
- More flexible DHCP Prefix Delegation (IPv6 DHCP-PD): The system now supports a broader range of prefixes, from /48 to /64, improving compatibility with various internet service providers.
- Router Advertisement (RA) and DHCPv6 server: These features are now enabled by default, simplifying IPv6 network setup.
- Resizable table columns: The web admin interface continues its adaptation for ultra-wide screens, with many configuration pages now allowing users to resize columns as needed for improved usability.
- Enhanced object search functionality: The search field within the SD-WAN routing configuration screen now supports more granular criteria, including route name, ID, objects, and object values like IP addresses and domains. Similarly, local ACL rules now also support object name and value searches, extending to content-based searches for more precise results.
- Default configuration changes: To streamline initial setups, default firewall rules and rule groups previously created during new firewall deployments have been removed. The initial configuration now only includes the default network rule and MTA rules. Furthermore, the default firewall rule group and the default gateway probe for custom gateways are now set to “None” by default.
Sophos continues its commitment to cybersecurity through a “Secure by Design” approach, enhancing the intrinsic security of its firewalls. This methodology involves the containerization of specific features and rigorous integrity checks on critical operating system files using mathematical checksums. Any detected checksum mismatch triggers a potential compromise alert, enabling monitoring teams to proactively identify possible security incidents affecting the firewall OS integrity. This proactive detection allows incident response and development teams to react swiftly to critical security events.
This update is now available for manual download and deployment by customers with any Sophos Firewall equipped with a valid license.
