Web Application Firewall (WAF) and AWS Shield

Web applications are constantly targeted by cyberattacks, including SQL injection, cross-site scripting, and Distributed Denial of Service (DDoS) attacks, which can compromise data security and disrupt services. To protect against such cyberattacks, it is essential to implement robust security measures that can detect, mitigate, and respond to malicious traffic while maintaining application performance and compliance. AWS provides specialized services like AWS WAF and AWS Shield to address these security challenges effectively.

AWS WAF

AWS WAF is a web application firewall that helps protect our web applications from common web exploits that could affect application availability, compromise security, or consume excessive resources. AWS WAF configures rules that allow, block, or monitor (count) web requests based on our predefined conditions. These conditions include IP addresses, HTTP headers, HTTP body, URI strings, SQL injection, and cross-site scripting. New rules can be deployed within minutes, letting us respond quickly to changing traffic patterns.
