DDoS Detection

L3/4 - Volumetric Attacks

Nexusguard’s NetShield DDoS Module defends against Layer 3 volumetric attacks, which overwhelm networks with massive traffic floods. Equipped with advanced filters, it enables SOCs to detect, analyze, and neutralize threats in real-time. Features such as time and threshold-based detection allow precise attack identification, while peacetime autobaselining establishes baselines from network traffic patterns to simplify anomaly detection. Per-host detection ensures granular monitoring of every device, providing full visibility and control over the network.

Network Threat Intelligence Feed (NTIF) Module: Complementing NetShield is the NTIF Module, powered by a dynamic IP reputation database. NTIF tracks malicious IPs and alerts against potential DDoS threats based on their historical behavior and risk profiles, adding an intelligence-driven layer of protection.

L7 - Application Attacks

Nexusguard’s WebShield activates after L3/L4 NetShield protection, delivering always-on security for HTTP/S traffic. Designed to defend against Layer 7 and resource-intensive attacks that specifically target websites, it ensures uninterrupted performance and reliability. 

WebShield operates with independent detection and mitigation policies, allowing for precise and flexible defense mechanisms. The detection policy defines Layer 7 conditions to identify and trigger alerts for potential application-based DDoS events as soon as an attack begins. This proactive approach ensures rapid response and robust protection, keeping websites secure and operational.

Alerts

Nexusguard’s Event Notifier App ensures timely awareness by delivering real-time alerts through email, SNMP Trap, or syslog. Featuring customizable alert levels, it enables proactive incident management, allowing for swift and effective responses to potential threats.

DDoS Mitigation

NetShield - Volumetric Attacks

NetShield leverages advanced DDoS mitigation techniques to defend against L3/L4 attacks. Its key features include:

  • Anti-Flooding Protection: A sophisticated set of rules combats a variety of flood attacks, such as IP, TCP, UDP, ICMP, SYN, SSL/TLS, and SIP floods. These attacks overwhelm systems by flooding them with excessive requests, depleting resources and disrupting legitimate traffic. By filtering out malicious traffic, systems remain operational and secure.
  • Traffic Policing: To maintain network stability, predefined traffic thresholds are enforced after mitigation, ensuring only manageable volumes of data are forwarded to other systems or networks. This prevents tunnel congestion and minimizes disruptions across interconnected environments.
  • Network Threat Intelligence Feed (NTIF): An IP reputation database identifies and blocks malicious IP addresses based on their historical behavior and risk profiles, stopping threats well before they can impact critical infrastructure.
WebShield - Application Attacks

WebShield crafts advanced L7 mitigation policies designed to block and mitigate DDoS threats effectively. Key features include:

  • HTTP Authentication: Suspicious requests are routed through Nexusguard’s intelligent HTTP authentication engine, which employs a sophisticated three-layered filtering system. The authentication level can be configured as low, medium, or high, or set to operate fully automated for seamless, adaptive protection.
  • Slow Attack Protection: This policy operates in three distinct modes to detect and block abnormally slow HTTP requests, preventing attackers from exploiting slow-rate techniques to disrupt services.
  • RangeAmp Attack Protection: WebShield tackles invalid requests that abuse HTTP range attributes, often used to manipulate CDN servers into amplifying traffic and overwhelming target sites. By neutralizing these exploits, WebShield ensures servers remain resilient against such sophisticated attacks.

Web Application Firewall (WAF)

OWASP Top 10

Nexusguard’s Web Application Firewall (WAF) utilizes advanced blocklist rules to mitigate known security threats, with a strong focus on addressing the OWASP Top 10 Most Critical Web Application Security Risks. Additionally, the WAF enhances web application security by implementing Secure Headers, which add an extra layer of protection, and CSRF tokens to ensure that HTTP requests originate from trusted domains.
