Symantec is a global leader in providing security, storage and systems management solutions to help businesses and consumers secure and manage their information. Headquartered in Mountain View, California, Symantec has operations in more than 40 countries. As a provider of protection tools against botnet infections, we have international experience in anti-botnet initiatives, and we welcome the opportunity to submit a response to the joint request for information of the Department of Commerce and the Department of Homeland Security on “Models to Advance Voluntary Corporate Notification to Consumers Regarding the Illicit Use of Computer Equipment by Botnets and Related Malware. ” As a key security provider who undoubtedly would play a role in such models, we focus our comments on issues within our own remit. For consistency, some questions are answered in groups rather than one-by-one.
