naive botnet C&C
spread bots and have them directly communicate back
problems with naive botnet C&C
- not stealthy. If someone catches a bot, they can trace back to the attacker
- not robust: only 1 method of communication
botnet C&C design considerations
- efficient and reliable
- stealthy
- resilient
bots require communication before an attack (T/F)
