Last night I presented a series of tips and gotchas whilst setting up a home lab for Malware and Packet collection.
It was well attended, and thanks for all the kind words. There were so many requests for my presentation and tips that when we recover from SANSFire, I will write another diary on more hints and tips but here are a couple:
1 - Roomate/Spouse/KId Alerting: Let them know you will be capturing traffic (Or not 2 - Power: Check power where your lab is, your home wiring may be in series [1]

And thanks again for all those who attended. Check back for more tips about running a lab at home (along with the Dionaea Virtual machine, when it is more stable.)

Home electrical circuits aren't wired in series - our devices are designed to run with a consistent AC voltage and a current that varies on demand. Outlets on a series circuit would have a very variable voltage. Two 120 V light bulbs in series on a 120 V circuit would be (approximately) half their intended brightness.
Home wiring is done in parallel. I think you intended to recommend that people not overload their circuit breakers. Watch how much current you draw through one pair of wires. Circuit breakers are designed to break a circuit before your wires get overloaded. If you put things like powerbars, extra outlets, and surge protectors in the circuit, sometimes you introduce a point of failure lower than that which the home's breaker was designed to protect against. |

@karl Thank you for the clarification, and pointing out the details.
That is exactly what I meant and will update the diary. |

Yeah, I suspect instead of "in series" he meant that home wiring is often daisy-chained from outlet to outlet. This is really common practice, at least in US residential construction. It leads to very strange symptoms when the neutral becomes open at an outlet early in the chain.
