Inside the application our protection system can identify advanced attacks that are attempting to exploit specific features of our application. Within the application we have a full understanding of the user initiating an action, the target of that action and whether that action should be allowed for that user. ![]() The solution is to design and integrate a detection and response system into the application itself. Imagine trying to design an effective building alarm system without any knowledge of how the building is designed or even where the doors and windows are located. This approach is just not sufficient to properly protect critical applications that process sensitive financial data or personal user information. While some detection is better than none, a generic product could never fully understand the intricacies of each custom web application. A WAF is able to detect generic application attacks such as basic SQL injection attacks or common actions of a known attack sequence. One potential solution is a web application firewall (WAF). We need to move into the application layer to understand our attackers. Antivirus is also out of the question since this is a signature based approach that knows nothing of custom web application vulnerabilities. Nor does a network based IDS system since it will have no insight to our application specific traffic. A firewall provides no protection its purpose is to allow users to access the application. Security approaches of previous years are not sufficient. How do we bridge the technology gap to implement appropriate security controls in our critical applications? The first step is to realize that in order to detect and respond to malicious activity at the application layer we need to be able to monitor and understand a user’s actions within the application. Just like in the real world, we would prefer to detect and prevent an attack instead of just responding after a compromise has occurred. We need to implement robust attack detection within the application to identify malicious users before they are successful in their attack. If our applications have any hope of standing up to such formidable opponents, then we need to move beyond just attempting to design our applications securely. The attackers are organized, motivated, and backed by a network of resources and talent. Despite the critical role they play, the security defenses within these applications are seriously lacking. From transferring money, to managing health records, web enabled applications handle immense amounts of sensitive data each day. Today’s applications are responsible for securely performing critical operations for individuals and businesses around the world. ![]() Put whatever you like here: news, screenshots, features, supporters, or remove this file and don’t use tabs at all.Ĭoncepts Application Layer Intrusion Detection There is more detailed information about the concepts as well as a getting started set of docs for developers at ![]() The book describing the framework and methodology are available via PDF or as a physical book on Lulu In addition, there is a reference implementation that provides a toolkit for building self-defending applications through real-time event detection and response appsensor github. The AppSensor project defines a conceptual framework and methodology that offers prescriptive guidance to implement application layer intrusion detection and automated response.
