Amazon AWS Web Application Firewall (WAF ) Launched



AWS WAF is a web application firewall that helps protect your web applications from common web exploits that could affect application availability, compromise security, or consume excessive resources. AWS WAF gives you control over which traffic to allow or block to your web application by defining customizable web security rules. You can use AWS WAF to create custom rules that block common attack patterns, such as SQL injection or cross-site scripting, and rules that are designed for your specific application. New rules can be deployed within minutes, letting you respond quickly to changing traffic patterns. Also, AWS WAF includes a full-featured API that you can use to automate the creation, deployment, and maintenance of web security rules. For more information go to




Amazon AWS Web Application Firewall (WAF ) Launched



AWS WAF is a web application firewall that helps protect web applications and APIs from attacks. It enables you to configure a set of rules called a web access control list (web ACL) that allow, block, or count web requests based on customizable web security rules and conditions that you define. For more information, see How AWS WAF Works.


AWS WAF is a web application firewall that lets you monitor the HTTP and HTTPS requests that are forwarded to Amazon CloudFront, an Amazon API Gateway REST API, an Application Load Balancer, an AWS AppSync GraphQL API, or an Amazon Cognito user pool. AWS WAF also lets you control access to your content. Based on conditions that you specify, such as the IP addresses that requests originate from or the values of query strings, the Amazon API Gateway REST API, CloudFront distribution, the Application Load Balancer, the AWS AppSync GraphQL API, or the Amazon Cognito user pool responds to requests either with the requested content or with an HTTP 403 status code (Forbidden). You also can configure CloudFront to return a custom error page when a request is blocked.


AWS WAF is a web application firewall that lets you monitor the HTTP and HTTPS requests thatare forwarded to CloudFront, and lets you control access to your content. Based on conditionsthat you specify, such as the values of query strings or the IP addresses that requestsoriginate from, CloudFront responds to requests either with the requested content or with anHTTP status code 403 (Forbidden). You can also configure CloudFront to return acustom error page when a request is blocked. For more information about AWS WAF, see theAWS WAF DeveloperGuide.


Implement inspection and protection: Inspect and filter your traffic at each layer. For example, use a web application firewall to help protect against inadvertent access at the application network layer. For Lambda functions, third-party tools can add application-layer firewalling to your runtime environment.


Adopt a layered defense (edge and in-region) security strategy with a web application firewall that aggregates threat intelligence from multiple sources including WebRoot BrightCloud and more than 250 predefined OWASP, application, and compliance-specific rules.


Ensure that Amazon Web Application Firewall (WAF) service is currently in use in order to protect your AWS-powered web applications from security exploits that could affect their availability and overall security, or consume excessive resources (resource starvation attacks). Amazon WAF is a web application firewall service that lets you monitor any HTTP(S) requests that are forwarded to AWS CloudFront or AWS ELB. To enable AWS WAF protection you simply create web Access Control Lists (ACLs), define the ACLs rules, which reference one or more conditions, and the actions to take when each rule is satisfied. Then the newly created WAF ACLs can be attached, for example, to the Amazon CloudFront CDN distribution used by your web applications. To quickly get started with AWS WAF you can also use AWS Pre-configured Protections, an automated solution that consists of a pre-configured AWS WAF template that includes a set of predefined ACL rules, which can be customized to best fit your requirements, designed to block common web-based attacks such as bad bots, Cross-Site Scripting and SQL Injection.


In order to enable AWS WAF as the web firewall service to protect your AWS-powered web applications from security exploits, you must create one or more web ACLs, each ACL containing rules and actions to perform when a rule is satisfied. Once the necessary rules and actions are defined, the new web ACL can be assigned to the CloudFront distribution used by your web application as CDN solution or to the Application Load Balancer, managed by the AWS ELB service, used by your application as load balancing solution. To create and assign your first AWS WAF web ACL, perform the following:


Amazon Web Services has launched its AWS Network Firewall, a managed firewall service for Virtual Private Cloud to deploy necessary network protection across all AWS workloads. The latest service from the cloud giant allows users to deploy and manage stateful inspections to protect AWS virtual networks.


AWS claims that security is their number one priority and have provided multiple firewall capabilities addressing specific security needs including Security Groups to protect Amazon Elastic Compute Cloud (EC2) instances, AWS Web Application Firewall (WAF) to protect web applications running on Amazon CloudFront, AWS Shield to protect against Distributed Denial of Service (DDoS) attacks, etc.


The Azure web application firewall (WAF) engine is the component that inspects traffic and determines whether a request includes a signature that represents a potential attack. When you use CRS 3.2 or later, your WAF runs the new WAF engine, which gives you higher performance and an improved set of features. When you use earlier versions of the CRS, your WAF runs on an older engine. New features will only be available on the new Azure WAF engine.


Defender for Cloud helps you prevent, detect, and respond to threats. It provides increased visibility into and control over the security of your Azure resources. Application Gateway is integrated with Defender for Cloud. Defender for Cloud scans your environment to detect unprotected web applications. It can recommend Application Gateway WAF to protect these vulnerable resources. You create the firewalls directly from Defender for Cloud. These WAF instances are integrated with Defender for Cloud. They send alerts and health information to Defender for Cloud for reporting.


More organizations and enterprises trust Barracuda Web Application Firewall to secure their applications running in public cloud than the next 3 most deployed solutions combined. The on premises Barracuda Web Application Firewall remains the go-to web application firewall for mid-market thanks to its unmatched value.


A web application firewall (WAF) provides web application security for online services from malicious security attacks such as SQL injection, cross-site scripting (XSS). WAF security detects and filters out threats which could degrade, compromise, or expose online applications to denial-of-service (DoS) attacks. WAF security examines HTTP traffic before it reaches the application server. They also protect against unauthorized transfer of data from the server.


OWASP is an international organization that allows the use of their tools, forums, code and other documents by anyone that has the end goal of improving application security or developing any new kind WAF security device. OWASP is not affiliated with any technology company and they support the informed use of commercial application security technology. Similar to many open-source security software projects, OWASP produces different types of materials in a collaborative and open-source manner. Their resources and conferences provide web application firewall training as well as best practices and source code.


Top web application firewalls use application intelligence to offer advanced WAF capabilities like real-time insights into application traffic, performance, security and threat landscape. This visibility gives administrators the flexibility to respond to the most sophisticated attacks.


When the Open Web Application Security Project (OWASP) identifies the most common vulnerabilities, WAFs allow administrators to create custom security rules to combat the list of potential attack methods. An intelligent WAF analyzes the security rules matching a particular transaction and provides a real-time view as attack patterns evolve. Based on this intelligence, the WAF can reduce false positives. While these features contribute to web application firewall benefits, there are still some weaknesses to be aware of.


Traditional web application security solutions do not provide visibility and security insights that administrators can use to create an effective application security posture. Enterprises need real-time visibility into application traffic, user experience, security and threat landscape, and application performance to identify and protect against the most sophisticated attacks. Appliance-based web application firewall (WAF) solutions do not leverage their privileged position in the path of application traffic and are black boxes when it comes to delivering application visibility.


A traditional firewall protects the flow of information between servers while WAFs are able to filter traffic for a specific web application. Network firewalls and web-application firewalls are complementary and can work together. WAF capabilities and traditional firewall security can combine port/protocol inspection and application-level inspection to prevent intrusion and utilize external intelligence sources.


Another distinction from traditional firewalls versus web application firewalls is that traditional security methods include network firewalls, intrusion detection systems (IDS) and intrusion prevention systems (IPS). These are effective at blocking illegitimate L3-L4 traffic, based on Open Systems Interconnection (OSI) model. Depending on the protocol being run, traditional firewalls can operate using a stateless method or a stateful method.Traditional firewalls cannot detect attacks unique to the security flaws in web applications because they do not understand Hypertext Transfer Protocol (HTTP) which occurs at layer 7 of the OSI model. They also only allow the port that sends and receives requested web pages from a HTTP server to be open or closed. This is why WAFs are important for preventing attacks like SQL injections, session hijacking and Cross-site Scripting (XSS).
