Abstract
Examples of the present disclosure describe systems and methods for providing security against IP spoofing. In aspects, network traffic associated with one or more data requests may be received by a device in a computing environment. The network traffic may be evaluated using one or more automated logic systems or algorithms to identify suspicious or malicious behavior. The automated logic systems or algorithms may implement one or more analyses, such as asymmetric routing analysis, hardware device analysis, user and/or network behavior analysis, etc. Upon identifying suspicious or malicious behavior, the automated logic systems or algorithms may apply a filter to one or more computing devices. For example, a filter for blocking network traffic associated with the suspicious or malicious behavior may be applied to a computing device that is in close geographic and/or logical proximity to an attacking computing device.
