A web application firewall (WAF) is a security device that helps protect web applications by enforcing security policies and preventing unauthorized access to resources.
There are a few key characteristics you should look for when selecting a WAF:
API gatekeeper functionality. A WAF that can act as an API gatekeeper is especially beneficial because it can help prevent unauthorized access to web application resources by enforcing policies related to the use of external APIs.
Configurable rule sets. A WAF should allow you to create configurable rule sets that Target specific attack vectors and vulnerabilities.
Robustness. A WAF should be robust and able to withstand a variety of attacks.
Integration with existing security infrastructure. A WAF should be able to integrate with your existing security infrastructure, such as intrusion detection/prevention systems and firewalls.
Network visibility. A WAF should allow you to see which hosts and ports are being used to access your web applications and what traffic is being sent and received.
The following are some considerations when selecting a WAF:
Type of security. You should decide which type of security you need: application-level security, which covers the web application itself; or web application security, which covers the security of the web application’s surrounding environment, including the web server and the underlying infrastructure.
Capabilities. Look for a WAF that has the following capabilities: rule management, policy enforcement, application layer inspection, and traffic shaping.
Deployment options. You should also consider the deployment options available for your WAF: on premise, in the cloud, or a hybrid deployment.
Conclusion
When selecting a web application firewall, you should consider the type of security you need, the capabilities available, the deployment options, and the type of traffic your web applications are receiving.
