The Korean government has responded to the distributed denial of service attacks this July by including rules that would require Internet service providers to enforce customers maintaining security software on their computers:

Exposed as defenseless against the powerful Internet attack that crippled scores of South Korean computers in July, the government has been considering more ways to strengthen the online security requirements for both individuals and companies.

However, it has now been revealed that the plans include blocking the Internet access of computer users failing to equip their devices with proper security programs, triggering a debate about whether policymakers are going over-the-top.

Korean government agencies have also started to release survey of the effectiveness of anti-virus software:

Around two-thirds of the locally-made anti-virus programs sold during the first half of this year failed to pick up malicious computer codes, according to a survey conducted by the Korea Communications Commission and the National Internet Development Agency of Korea.

Despite the so-called “denial-of-service” attacks last month that paralyzed major Web sites here, 84 local anti-virus programs out of the 134 surveyed failed to detect a single malicious code from the 1,500 online samples tested.
