3: Limiting the spread of malware

Group members: keith, Andrew, David Barrera

Ideas:

• Multiple control/chokepoints where malware is looked for. This way, it's more difficult for attackers to take over several control points and for malware to remain unnoticed.
• Heterogeneous systems help limit the spread of malware too. There's 2 points here. (1) If we're designing this system where we're all masters of our own domains, then we're likely to have different system configurations. However (2), if we want to communicate and interact with other domains, we need some standardized communication layer or mechanism. Standardization is very closely tied to homogeneous.
• There should be consequences if you harbor malware or if malware originates from within your domain. This could be and incentive to help people be more proactive in terms of security.
