ABSTRACT
Content filtering schemes are common yet controversial tools for governments to mitigate cybersecurity threats. We empirically investigate the policy effect on security in the context of the Chinese Green Dam Youth Escort (GDYE) filter scheme and the Australian National Filter Scheme. By applying difference-in differences estimations to a cyberattack dataset from the DShield distributed intrusion detection system from July 2005 to June 2010, we conclude that the schemes weaken security. Our result shows that the security deterioration of the filter schemes originates from the use of circumvention tools from users and defiance from attackers. Our finding suggests that policymakers should not overlook the strategic reactions from different parties while focusing on the technical benefit of such policies
