WAF Security Architecture shows that a wireless access capability was first introduced with the intention of providing a secure layer that could provide authentication and encryption to a Wi-Fi hotspot. Today, however, it has grown so much that it is starting to replace WAN VPNs altogether. What is WAF?
WAFs allow for the detection of security flaws within a web application before the compromise of the application. These security flaws are detected by detecting malicious websites that attempt to submit cross-site request forgeries to the server. Once these cross-site request forgeries are identified, the corresponding vulnerable software is stopped from processing and executing. The malicious website then receives a "condition failed" response from the server, which makes it easy to detect and stop.
There are several different ways that a malicious web page can trigger this condition failure. For instance, scripts used for script injection attacks can trigger a Condition handlers within the vulnerable web application firewall (if you have implemented one). Another method is for the user to click on a malicious link (which can be installed as an application, downloaded or uploaded by the victim). Lastly, visiting a malicious site or executing a malicious ware application can also trigger conditions. In this case, the browser will refuse to allow the connection. It is also possible that web pages that do not follow a specific protocol will cause this condition to be triggered as well.
In addition to preventing such attacks from happening, a waf security configuration can also prevent certain attacks from happening. Some attacks come from cross-site scripting vulnerabilities, where a site that is vulnerable opens a back door to attacker-controlled pages. Another vulnerability is when scripts used for reverse site analysis attacks open a back channel to attack servers that do not support the selected protocol. This scenario, where scripts can intentionally or accidentally change the network's configuration, is referred to as a 'CWNA Effect.'
In order to prevent these types of vulnerabilities from occurring in your enterprise network, you need to build a strong waf security architecture. The structure should include all the layers of the application firewall to prevent unauthorized access from outside parties and provide centralized monitoring to prevent data leakage attacks. In order to prevent data leakage attacks, you should restrict all data that travels through the firewall to avoid sensitive information getting compromised. You should also restrict all data that is stored on the web server to avoid leaking information back to the attacker.
There are many benefits that can be achieved through the use of a solution. For instance, by using pre-designed wafs, you can reduce the cost of your web application firewall and improve end-user experience. In addition to this, a solution can also detect and block suspicious behavior. Furthermore, the proper management of traffic policies can help you determine which traffic is malicious and which is benign.
Many people do not realize it, but there are many false positives found in the majority of the enterprise-wide networks. False positives are not really issues in themselves, but they contribute to the overall bandwidth usage and can slow down the response time of web applications. To counter this issue, most of the enterprise-level WAF solutions provide traffic monitoring and management services. They can also detect and eliminate false positives quickly, thereby improving end user experience and reducing cost.
Another issue that is commonly encountered is performance degradation caused by overload of traffic on the web application servers. To counter this problem, most of the enterprise-level WAF services available in the market offer good monitoring and management services to monitor web application firewall policy and traffic. In addition to this, you can use the services of a WAF manager to manage and configure various types of firewalls on your network. To conclude, a good enterprise level WAF solution offers complete web application security along with effective monitoring and management capabilities along with high levels of deployment flexibility.
