Web Application Firewall
A WAF or web application firewall helps protect web applications by filtering and monitoring HTTP traffic between a web application and the Internet. It typically protects web applications against attacks such as cross-site forgery, cross-site-scripting (XSS), file inclusion and SQL injection, among others. WAF provides OSI Layer 7 protection. This layer is designed to protect against focused attacks. This attack mitigation method is often part of a suite of tools that together form a holistic defense against various attack vectors. By placing a WAF in front of a web application, a shield is placed between the web application and the Internet. Whereas a proxy server protects the identity of a client machine using an intermediary, a WAF is a kind of reverse proxy. By ensuring that clients pass through the WAF before reaching the server, it protects the server from malicious access to it.
DDoS (Distrubuted Denial of Service Attack) means creating a serious instantaneous intensity for all services of the servers and increasing the resource consumption to the peak points. Millions of IP addresses that have been hijacked in general are much more commonly used to create these artificial traffic. DDoS, which draws attention as a cyber attack model, is generally done with the help of botnets created by hackers. It is one of the attack types that cause serious vulnerabilities in servers. If you think that DDoS symptoms are experienced in your system, it is very important to take early precautions as it is one of the best ways of defense. However, it requires the right technology and expertise to distinguish these symptoms from the instant and normal performance increase/decrease experienced in your system. In terms of businesses, the well-designed network infrastructure and the high level of system and TCP/IP knowledge of the relevant personnel are at the top of the protection measures. In order to be protected from such attacks at the highest level, it is necessary to take precautions both within the internet provider and within your organization. We provide complete protection at this layer by positioning DDoS protection devices for the measures you will take in your organization and integrating them into the existing structure.
