AWS Web Application Firewall Blog

Ensure advanced security for Web Apps and API through effective implementation of AWS WAF services

AWS WAF (Web Application Firewall) is a robust security tool that helps protect web applications and API from external threats like SQL injection and cross site scripting attacks. It consists of a set of rules that control access to the applications based on the IP addresses, geographic location, or user-agent strings.

AWS WAF helps in the effective monitoring of HTTP and HTTPS requests that are forwarded to the web application infrastructure. 

AWS WAF also provides logging and monitoring capabilities, allowing customers to review and analyze traffic patterns and security events to identify potential security threats and take appropriate actions.

Common threats faced by API and web applications.

Web applications and API are vulnerable to various kinds of attacks that lead to unprecedented downtime, privacy intrusion, or high bandwidth usage. The most common web attacks include:

  • DDoS attacks: This involves flooding a web application or API with traffic leading to application crashing or becoming unresponsive.
  • SQL injection: The process of inserting malicious SQL statements into a web application’s input fields by attackers to gain access to sensitive information stored in the database is known as SQL injection. 
  • Cross-site scripting: This involves injecting malicious scripts into a web page or API response which is then executed by the victim’s browser. These scripts can rewrite the content of the HTML pages.   

AWS helps protect web applications and API from typical vulnerabilities by allowing the users to set rules to monitor web traffic and help minimize web attacks. 

Steps to configure AWS WAF to protect web resources

  • Start by defining your security requirements, determine which resources you need to protect and the type of attacks that you want to secure your applications from.
  • Create a web ACL (Access Control List) which consists of a set of rules to block traffic from accessing the web application. 
  • The next step involves configuring a set of rules to protect web applications. AWS WAF consists of pre-configured rules that protect web applications against common attacks. This set of rules can be customized according to specific needs. 
  • Next define the conditions when the rule needs to be triggered. These conditions comprise of expressions that specify the attributes of the web requests, such as the IP address of the client or the type of the browser being used.
  • Finally, by integrating the Web ACL with the CloudFront distribution, API Gateway, or Application Load Balancer, you can deploy it to your web application.

Benefits of AWS WAF:

AWS WAF plays a major role in protecting your website against web attacks based on your specific criteria. The characteristics of web requests such as the following can be used to define specific criteria:

  • Requests originating from IP addresses.
  • The country from where the requests originate.
  • Header value of the requests.
  • The strings are included in requests, either specifically or by matching regular expression (regex) patterns.
  • Length of requests.
  • SQL injection that implies malicious SQL code.
  • Cross-site scripting that includes malicious script.
  • Rules that allow, block, or count web requests that meet certain criteria. A rule can also be configured to block or count web requests that meet the specified criteria but exceed a specified number of requests in a 5-minute period as well.
  • Rules that can be reused for multiple web applications.
  • A set of managed rule groups from AWS and AWS Marketplace sellers.
  • An analysis of real-time metrics and sample web requests.
  • Implementation of AWS WAF API for Automated administration.

Features of AWS WAF for robust protection against web attacks

  • Protection against common web exploits: AWS WAF allows you to protect your web applications against common web exploits such as SQL injection, cross-site scripting (XSS), and other types of attacks.
  • Customizable rules: You can customize rules in AWS WAF to match your specific needs. This allows you to create rules that are tailored to your application and protect against the most common threats.
  • Scalability: AWS WAF is designed to be scalable, which means it can handle large volumes of traffic without impacting application performance.
  • Integration with other AWS services: AWS WAF can be integrated with other AWS services, such as Amazon CloudFront, AWS Elastic Load Balancing, and AWS Application Load Balancer. This allows you to protect your entire application stack, from the front-end to the back end.
  • Real-time monitoring and logging: AWS WAF provide real-time monitoring and logging capabilities, which allows you to detect and respond to threats in real-time.
  • Cost-effective: AWS WAF is a cost-effective solution for protecting your web applications. Resources are only charged based on usage, with no upfront costs or long-term contracts.

How to optimize performance through effective use of AWS WAF?

AWS WAF services lead to performance implications such as latency, higher processing overheads, and increased costs when not implemented in the right way. To avoid such implications, it is suggested to follow the below methods and optimize performance.

  • Customized use of AWS WAF: Not all web applications require a web application firewall. If your web application is not vulnerable to common web-based attacks, you may not need to use AWS WAF.
  • Use caching: Caching can help to reduce the number of requests that need to be inspected by AWS WAF. You can use caching solutions like Amazon CloudFront or Amazon Elasticache to cache frequently accessed content.
  • Use Amazon API Gateway: Amazon API Gateway can help to reduce the number of requests that need to be inspected by AWS WAF. You can use API Gateway to route requests to specific endpoints, reducing the number of requests that need to be inspected.
  • Optimize your AWS WAF rules: AWS WAF allows you to create custom rules to block or allow traffic. You can optimize these rules to reduce the processing overhead of AWS WAF.
  • Monitor your AWS WAF usage: Monitoring your AWS WAF usage can help you identify any performance bottlenecks. You can use Amazon CloudWatch to monitor your AWS WAF usage and identify any issues.

Best practices for implementing AWS WAF

AWS WAF best practices ensure the web applications are well protected from common threats and vulnerabilities. 

Some of the best practices for AWS WAF include:

  • Using managed rules
  • Create rules based on the security requirements to filter traffic.
  • Monitor AWS WAF logs to identify potential threats.
  • Regularly update AWS WAF rules to ensure the application is protected against the latest threats.
