DDoS L7 attack methods

DDoS attacks are one of the most popular types of hacker attacks. It consists of creating a situation where a particular site or server begins to fail or stops working under a huge influx of requests. Small companies with limited budgets suffer most from DDoS attacks and therefore are unable to detect and filter out suspicious requests in a timely manner. Modern hackers have significant resources and can conduct simultaneous attacks from thousands or even millions of “infected” computers, so this type of attack can also affect large information resources, as well as representative offices of various companies. Of course, the availability of modern protection (Cloudflare) greatly reduces the risk of serious consequences for the web resource or page.

L7 DDoS attacks

Layer 7 attacks are aimed at degrading a Web application. They include attacks aimed at stealing personal data from memory, disk, as well as repetitive search queries. GET/POST/HTTP Flood attacks can also be classified as L7 attacks.

A distinctive feature of such attacks is sending an uncountable number of requests from public IP addresses. The most prominent example: marketplaces. If an attacker wants to disrupt an online marketplace, he will probably use thousands of computers to send http/https-type requests. They can imitate registration of a new user or search for goods. It’s very difficult to fight L7 DDoS attacks. They are successfully disguised as an ordinary request, so it is difficult to distinguish a malicious request (spam) from an ordinary one. Moreover, if an intruder has enough IP addresses, he can send 2-3 requests from each of them, so the standard method in the form of IP block will not work.

Correlation analysis, behavioral analysis should be performed to protect against Layer 7 attacks, monitoring is also effective. They are needed for analysis of incoming requests in order to detect obvious spam. Blocking IP addresses by geolocation or autonomous system (AS) is only partially effective, because normal requests can be blocked along with malicious ones. And if a company provides services in a particular region from which spam requests come, there is a serious risk of losing some of its users.

Displaying captchas is more effective. Then ordinary visitors to the site will be able to pass a simple check, and the bots will remain disarmed. To organize protection from such attacks it is enough to use methods like CrowdSec and Qrator.
