DESCRIPTION
Web application performance and security are critical to innovation. Akamai's Web Application Firewall (WAF) is a highly scalable edge defense service architected to detect and mitigate potential attacks, including SQL injection attacks, in HTTP and HTTPs traffic as they pass through Akamai's Intelligent Platform in their attempt to reach origin data centers. WAF is designed to scale instantly to preserve performance and filter attack traffic close to the source, protecting your infrastructure and keeping your web applications up and running.

Moving From Network to Application Layer
Target of Tradi,onal DDoS A2acks
Network Layer
(Layers 3/4)
Application Layer
(Layer 7)
Where increasing number of a2acks are focused

Web Application Firewall Highlights
• Operates at the network edge – over 100,000 servers • Inspects requests and responses for malicious content and info leakage • Inspects packets to protect against attacks such as SQL Injections &
Cross-Site Scripts • Configurable to log or block activities against policy • Protects organizations against application layer attacks propagated via
HTTP and HTTPS • Enables compliance with PCI DSS 1.2 section 6.6 • Provides advanced rate controls (behavioral based protections) • Propagates quickly (~30 minutes) • Configured via portal

Akamai Intelligent Platform™ Deflecting Network Layer Attacks at the Edge Network Layer attack mitigation § Built-in protection is “always on” § Only Port 80 (HTTP) or Port 443 (HTTPS) traffic
allowed on Platform o All other traffic dropped at the Akamai Edge
• Attack traffic never makes it onto Platform • Customer not charged for traffic dropped at Edge
o Absorbs attack requests without requiring identification o Requires CNAME onto Akamai Intelligent Platform
Absorbs attacks through massive scale § ~5.5 Tbps average throughput; up to 8Tbps § Distribution of HTTP request traffic across 100,000+
servers; 1,100+ networks § No re-routing, added latency, or point of failure
Examples of attacks types dropped at Akamai Edge § UDP Fragments § ICMP Floods § SYN Floods § ACK Floods § RESET Floods § UDP Floods

Custom Rules Web Application Firewall Description § WAF Custom Rules implemented
in Akamai metadata written by Akamai Professional Services
§ Rules are created and managed in customer portal
§ Rules are then associated with firewall policies and deployed with WAF in 45 minutes
The Result § New rule logic can be built to handle
specific use cases for the customer § Rules can be built that execute when
one or more baseline rules or rate control rules match
§ Output of application vulnerability products can be implemented as “virtual patches”
§ Advanced piping to user validation actions can be achieved (prioritization)

Adaptive Rate Controls Malicious Behavior Detection
§ Specify number of requests per second against a given URL o Controls requests based on behavior
pattern – not request structure • Use client IP address, session ID, cookies, etc.
§ Configure rate categories to control request rates against digital properties • Mitigate rate-based DDoS attacks
§ Statistics collected for 3 request phases o Client Request – Client to Akamai Server o Forward Request – Akamai Server to Origin o Forward Response – Origin to Akamai Server
§ Statistics collected allow us to ignore large proxies and pick out a malicious user hiding behind a proxy
§ Statistics collected allow for detection of pathological behavior by a client o Request rate is excessive for any stage o Requests causing too many Origin errors
