Question:How hard is it to "hack" a wireless security system? For example, if I
installed one of the wireless key fobs or had a wireless handheld
keypads, would it be difficult for a sophisticated burglar to simply
disarm the security system?
What security mechanisms, if any, are in place to protect against this
type of attack. Are their security codes you need to put into the key
fob/handheld. Do these keys rotate or are they static. How many
possible codes are there (to prevent an attacker from trying all
codes).
I expect buglars with advanced techniques to do this is unlikely. I'm
just curious from an academic point of view.
I'm not sure if this is the appropriate venue to discuss the topic,
but, if a burglar would attempt to do this. What would they need? Some
sort of RF sniffer? Or just a programmable fob?
Thanks in advance, I know this issue may be controversial considering
all the other postings I've on wireless vs hard-wired.
Answer:A perp couldn't use just any wireless keypad of the same brand as your
system. They have to be "enrolled" to your particular panel. If a perp
were to obtain the wireless keypad for *your* system it would take him
awhile to discover the four digit code you use to disarm. Some panels
employ an anti-hacking feature that your installer can enable (three or four
wrong code entries and the system "locks" for a period of time programmed by
your installer *and* transmits a code to the Central Station). He could
also inadvertently enter a "duress" code with some rather embarassing
results (for him). A keyfob with a single button "off" wouldn't present any
difficulty (which is why I normally recommend people use fobs to *arm* the
system, but not *disarm* it). If you *do* manage to lose a wireless keypad
or fob, though, make sure you contact your security company so they can
disable it (this can be accomplished by downloading the information to your
system without having a service man actually visit).
