37、eful examination.So it isnt surprising that you ll find plenty of strong opinions about the potential vulnerabilities of popular home-security systems.B)The most likely type of burglary(入室盗窃)by far is the unsophisticated crime of opportunity,usually involving a broken window or some forced entry.Acc

38、ording to the FBI,crimes like these accounted for roughly two-thirds of all household burglaries in the US in 2013.The wide majority of the rest were illegal,unforced entries that resulted from something like a window being left open.The odds of criminal using technical means to bypass a security sy

39、stem are so small that the FBI doesn t even track those statistics.C)One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether.With wired setups,the fear is that a burglar(入室盗贼)might be able to shut your system down sim

40、ply by cutting the right cable.With a wireless setup,you stick battery-powered sensors up around your home that keep an eye on windows,doors,motion,and more.If they detect something wrong while the system is armed,they ll transmit a wireless alert signal to a base station that will then raise the al

41、arm.That approach will eliminate most cord-cutting concerns but what about their wireless equivalent,jamming?With the right device tuned to the right frequency,what s to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?D)Jamming concerns are not

42、hing new,and they re not unique to security systems.Any device that s built to receive a wireless signal at a specific frequency can be overwhelmed by a stronger signal coming in on the same frequency.For comparison,let s say you wanted to“jam”a conversation between two people all you d need to do i

43、s yell in the listener s ear.E)Security devices are required to list the frequencies they broadcast on that means that a potential thief can find what they need to know with minimal-13-Googling.They will,however,need to know what system they re looking for.If you have a sign in your yard declaring w

44、hat setup you use,that d point them in the right direction,though at that point,we re talking about a highly targeted,semi-sophisticated attack,and not the sort of forced-entry attack that makes up the majority of burglaries.It s easier to find and acquire jamming equipment for some frequencies than

45、 it is for others.F)Wireless security providers will often take steps to help combat the threat of jamming attacks.SimpliSafe,winner of our Editors Choice distinction,utilizes a special system that s capable of separating incidental RF interference from targeted jamming attacks.When the system think

46、s it s being jammed,it ll notify you via push alert(推送警报).From there,it s up to you to sound the alarm manually.G)SimpliSafe was singled out in one recent article on jamming,complete with a video showing the entire system being effectively bypassed with handheld jamming equipment.After taking approp

47、riate measure to contain the RF interference to our test lab,we tested the attack out for ourselves,and were able to verify that it is possible with the right equipment.However,we also verified that SimpliSafe s anti-jamming system works.It caught us in the act,sent an alert to my smartphone,and als

48、o listed our RF interference on the system s event log.The team behind the article and video in question make no mention of the system,or whether or not it detected them.H)We like the unique nature of that software.It means that a thief likely wouldn t be able to Google how the system works,then fig

49、ure out a way around it Even if they could,SimpliSafe claims that its system is always evolving,and that it varies slightly from system to system,which means there wouldn t be a universal magic formula for cracking it Other systems also seem confident on the subject of jamming.The team at Frontpoint

50、 addresses the issue in a blog on its site,citing their own jam protection software and claiming that there aren t any documented cases of a successful jam attack since the company began offering wireless security sensors in the 1980s.-14-I)Jamming attacks are absolutely possible.As said before,with
