Understanding WAF+LB #
WAF+LB seamlessly integrates the protective capabilities of a Web Application Firewall with the traffic management prowess of a Load Balancer. By doing so, it not only fortifies web applications against cyber threats but also ensures smooth traffic handling across server clusters.
Key Features of WAF+LB #
Advanced Security Measures #
WAF+LB employs sophisticated security protocols to shield web applications from a spectrum of cyber attacks, including SQL injection, cross-site scripting (XSS), and DDoS assaults. By analyzing incoming traffic patterns, it filters out malicious requests, bolstering the application layer’s defense.
Precise Access Control #
Administrators wield granular control over access policies, dictating who can interact with specific application resources. This fine-tuned access control mechanism helps thwart unauthorized access attempts and maintains compliance with regulatory standards.
SSL/TLS Offloading Capability #
With SSL/TLS offloading, WAF+LB relieves backend servers of the computational burden associated with encryption tasks. By terminating secure connections at the load balancer level, it optimizes server performance while upholding stringent encryption standards for data protection.
Comprehensive DDoS Protection #
WAF+LB stands ready to counter both volumetric and application-layer DDoS attacks in real time. By swiftly identifying and mitigating malicious traffic, it ensures uninterrupted service availability and preserves the integrity of web applications under siege.
Efficient Traffic Distribution #
Leveraging intelligent load balancing algorithms, WAF+LB distributes incoming traffic across server clusters based on predefined criteria such as server health and response time. This dynamic traffic management optimizes resource utilization and sustains high availability even during peak loads.
Real-time Monitoring and Logging #
WAF+LB provides administrators with real-time visibility into web traffic patterns, security incidents, and performance metrics. Detailed logs facilitate proactive threat detection, incident response, and compliance auditing, empowering organizations to maintain a robust security posture.
Main RELIANOID’s WAF+LB features #
RELIANOID is an application delivery controller (ADC) that combines load balancing (LB) and web application firewall (WAF) functionalities. The integration of these features provides a comprehensive solution for optimizing the performance and security of web applications. Here are some key features of RELIANOID in terms of WAF and LB:
Load Balancing #
Distribution Algorithms: RELIANOID supports various load-balancing algorithms such as Round Robin, Least Connections, Source IP Hash, etc., allowing efficient distribution of traffic among backend servers.
Persistence: Session persistence mechanisms ensure that requests from the same client are consistently directed to the same backend server, maintaining session integrity.
Health Checks: RELIANOID conducts regular health checks on backend servers, dynamically adjusting the load distribution based on server health and responsiveness.
Web Application Firewall (WAF) #
Rule-Based Protection: RELIANOID WAF allows the creation of custom rules to protect against common web application vulnerabilities, such as SQL injection, Cross-Site Scripting (XSS), and more.
Signature-Based Protections: Utilizes signatures and patterns to identify and block known attack patterns or exploits.
Regular Rule Updates: WAF rules can be regularly updated to adapt to emerging threats and vulnerabilities.
Security and Access Control #
Access Policies: RELIANOID allows administrators to define access policies based on IP addresses, geographical locations, or other criteria, providing granular control over who can access the web applications.
SSL Offloading: RELIANOID can offload SSL/TLS encryption, improving performance while still ensuring secure communication between clients and the load balancer.
Global Server Load Balancing (GSLB) #
Multi-Site Load Balancing: RELIANOID supports GSLB to distribute traffic across multiple data centers or geographically distributed servers, improving availability and resilience.
Logging and Monitoring #
Real-Time Monitoring: Provides real-time monitoring of traffic, server health, and other performance metrics through the RELIANOID web interface.
Logging and Reporting: Generates logs and reports on security events, traffic patterns, and performance metrics, aiding in troubleshooting and compliance.
High Availability and Redundancy #
Clustering: RELIANOID supports clustering for high availability and redundancy, ensuring continuous operation even in the event of hardware or software failures.
Customization and Flexibility #
Customizable Policies: Administrators can customize WAF policies, load balancing settings, and other configurations to suit the specific requirements of their web applications.
REST API: RELIANOID provides a RESTful API for automation and integration with other systems.
Scalability #
Scalable Architecture: RELIANOID is designed to scale horizontally, allowing for the addition of more resources or nodes to handle increased traffic and workload.
IPv6 Support #
IPv6 Compatibility: RELIANOID supports IPv6, ensuring compatibility with modern networking protocols.
Conclusion #
In today’s cybersecurity landscape, where threats are omnipresent and web traffic is incessant, WAF+LB emerges as a strategic asset for organizations. By seamlessly blending security and scalability, WAF+LB ensures that web applications remain resilient, high-performing, and immune to malicious intrusions. This is one of our strengths at RELIANOID.
As organizations strive to safeguard their digital assets and deliver seamless user experiences, the fusion of Web Application Firewall with Load Balancer in WAF+LB represents a proactive step towards achieving these objectives.
