Abstract: Embodiments of the present disclosure relate to a method and apparatus for detecting traffic. The method includes: acquiring traffic information of at least two dimensions of a target IP; determining whether the traffic information of the at least two dimensions contains traffic information exceeding an abnormal traffic threshold of a corresponding dimension of the target IP; and in response to determining that the traffic information of the at least two dimensions contains the traffic information exceeding the abnormal traffic threshold of the corresponding dimension, determining that the traffic of the target IP is abnormal.

Abstract: Embodiments of the present disclosure relate to a method and apparatus for processing data. A method may include: receiving an access request to access a target domain name; converting the target domain name into a preset high defense domain name;querying an IP corresponding to the high defense domain name in a domain name system; and sending the access request according to the IP corresponding to the high defense domain name; where in a case that an EIP corresponding to the target domain name enables a black hole, the IP corresponding to the high defense domain name in the domain name system is a preset high defense IP, and in a case that the EIP corresponding to the target domain name closes the black hole, the IP corresponding to the high defense domain name in the domain name system is the EIP of the target domain name.
