Web Application Firewall (WAF)
By Georg Jonkin

The digital landscape is constantly evolving, but unfortunately so are the threats to it. The security of your web applications is crucial to the success of your business: a web application firewall (WAF) can help you protect your digital applications and services. In this article, you will learn how a WAF works and why the integration of a Security Information and Event Management System (SIEM) is a smart decision.

What is a web application firewall (WAF)?

A WAF is an advanced security solution that serves as a protective shield for your web applications. It monitors web traffic, uses artificial intelligence to detect malicious activity and blocks potential threats to keep your applications secure. Machine learning allows our WAF to implement this - previously time-consuming and manual - process automatically.  It relies on rule sets, anomaly detection and behavioural analysis to ward off common attacks such as cross-site scripting (XSS) or structured query language injection (SQLi). With its ability to recognise patterns of attack vectors, our WAF provides both preventative and forensic control, even when your IT security department is not on duty. As the attacks are already fended off at the edge, i.e. at the attacker, your company servers and networks remain unaffected.

Main features of a web application firewall

  1. Data traffic filtering: A WAF analyses incoming and outgoing web traffic to automatically block malicious requests and prevent vulnerabilities.
  2. Bot management: A WAF can differentiate between legitimate users and malicious bots and block unwanted bots depending on the situation. 
  3. Virtual patching: A WAF can eliminate vulnerabilities in web applications without changing the code. 
  4. DDoS protection: A WAF protects against brute force attacks and excessive traffic. 
  5. Logging and monitoring: Provides real-time monitoring and detailed logs..

Why integrate web application firewalls with SIEM?

The integration of WAFs with SIEM platforms offers many advantages: SIEM links security events and shares threat data between different tools. This enables centralised monitoring and therefore strong protection against security risks.

3 reasons to record your WAF events:

Security incidents & data breaches: Collect logs and analyse attack patterns to detect suspicious activity. Monitor real-time log data where our WAF both highlights and filters incidents so you can immediately see where manual adjustment is needed.

Security posture: Set up event notifications to track changes in your security posture and instantly recognise relevant incidents on your network. Define notification filters and process notifications efficiently.

Compliance monitoring: Identify applicable security standards, define compliance requirements and schedule regular checks.
