The Essential Shield for Your Web Application Firewall (WAF)


What is a Web Application Firewall (WAF)?

How does WAF work?

  • Signature-based detection: WAFs configured to detect and block known attack signatures. Attack signatures patterns of data that are typically associated with known attacks.
  • Heuristic detection: WAFs can also use heuristics to detect and block attacks. Heuristics are rules that are based on the behavior of known attacks.
  • Anomaly detection: WAFs can also use anomaly detection to detect and block attacks. Anomaly detection is based on the idea that attacks are typically anomalous, or unusual.

What is the benefits of using WAF ?

  • Protection from common attacks: WAFs can protect web applications from common attacks, such as XSS, SQL injection, and command injection.
  • Reduced risk of data breaches: WAFs help to reduce the risk of data breaches by blocking attacks that are designed to steal sensitive data.
  • Improved compliance: WAFs can help organizations to comply with industry regulations, such as PCI DSS and HIPAA.

Types of WAFs:

  •  On-premises WAFs are installed on the customer’s own hardware.
  • Cloud-based WAFs are hosted by a third-party provider.

Additional tips for using WAFs:

  • Keep the WAF up to date: WAF vendors regularly release updates that include new signatures and rules. It is important to keep the WAF up to date to ensure that it is able to detect and block the latest attacks.
  • Monitor the WAF logs: WAFs generate logs that contain information about the traffic that they have filtered and monitored. It is important to monitor the logs to identify any potential attacks.
