US Patent 9832209 Systems and methods for managing network security

A computer-implemented method for managing network security may include identifying a set of trusted Internet domains, identifying traffic information that indicates Internet traffic volume for each trusted Internet domain in the set of trusted Internet domains, and analyzing the traffic information to select, from the set of trusted Internet domains, a subset of trusted Internet domains that each have higher Internet traffic volume than one or more other trusted Internet domains in the set of trusted Internet domains. The method may also include including the selected subset of trusted Internet domains in an Internet domain whitelist. The method may further include configuring a network gateway system to perform a less intensive scan on Internet traffic that originates from an Internet domain identified in the Internet domain whitelist than on traffic that originates from other Internet domains. Various other methods, systems, and computer-readable media are also disclosed.
