During the dynamic verification process, different detection codes will be generated according to the threat situation to increase the unpredictability of the application, increase the difficulty for an attacker or automated tool to impersonate a legitimate client, and effectively overcome the security challenge that the existing terminal perception products using static acquisition code can be easily bypassed after reversed.
Dynamically encapsulate the bottom-layer code of the web page to hide the attack entries deeply and avoid becoming a target of network attacks. The encapsulation algorithms change every time new responses come in, so that the attackers will find it impossible to predict the behaviors of servers, which greatly increases the difficulty of the attack.
Dynamic obfuscate the sensitive data to protect the contents of requests issued by users, so as to effectively prevent fake request, injection and man-in-the-middle attacks including request forgery, malicious code injection, and tapping or tampering transaction data. Each obfuscation uses a different algorithm, making it impossible for an attacker to predict the obfuscation algorithm and key, which increases the difficulty of the attack.
Attaching one-time token to legally requested URLs blocks illegal request issued by attackers who attempt to bypass business logic. Dynamic token can provide protections against various automated malicious actions such as unauthorized access, privilege escalation, website backdoor attacks, replay attacks and advanced DDoS.
Aiming at the suspected tool access behaviors, dynamic challenge can identify the anthropomorphic behavior of advanced bots. Dynamic challenge solves the problem that traditional challenge recognition always relies on a fixed template. Through the introduction of dynamic change technology, the form and content of each challenge are different, which makes it more difficult for attackers to identify and bypass.
