【说明】
某创业型公司乙在201 5年1月，凭借着报价低的优势中标承接了—个信息系统工程项目。项目建设内容主要包括建设方甲公司的北京总公司ERP信息系统建设，以及甲公司成都分公司的机房改造项目。甲乙两公司协商签订了工程额为100万元的总价台同，工期为一年。
乙公司指派有过ERP项目经验的张工承担项目经理，困公司还处于创业期间，所以公司管理层非常注重成本的控制，要求项目经理严格控制成本，每周汇报面目的实际花费。为了满足低成本的要求，考虑到北京、成都两地的材料、差旅费用等问题，在征得甲公司与管理层的同意后，张工将机房改造工程外包给成都当地的丙公司，并在台同中要求丙公司必须在2015年底之前完工。
项目执行期间．张工借派了—名成本控制专员。负责每周统计该项目ERP部分所发生的费用。同时向管理层提交费用统计报告。项目进展到6月份。项目ERP部分实际发生的总费用为30万元。成都赶上了梅雨季节，丙公司反馈。因机房低处于某大厦的—层，太潮湿，机房改造工程被迫暂停。待梅雨季节过后继续施工。
项目执行到2015年底，机房改造项目已确定无法在2016年1月如期完工，ERP部分虽然基本到了后期的测试阶段，但其总费用也已经达到了60万元，

Can Burglars Jam Your Wireless Security System？
[A]Any product that promises to protect your home deserves careful examination. So it isn’t 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. According to the FBI, crimes like these accounted 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 a criminal using technical means to bypass a security system 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 simply 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 alarm. 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 nothing 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 is 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 Googling. They will, however, need so know what system they’re looking for. If you have a sign in your yard declaring what 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 forced-entry attack that makes up the majority of burglaries. It’s easier to find and acquire jamming equipment for some frequencies than it is for others.
[F] Wireless security providers will often take steps to help combat the threat of jamming attacks. SimpliSafe, winner of our Editor’s Choice distinction, utilizes a special system that’s capable of separating incidental RF interference from targeted jamming attacks. When the system thinks 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 appropriate measures to contain the RF interference to our test lab, we tested the attack out for ourselves, and were able to verify that it’s 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 also 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 in 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 figure 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 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 successful jam attack since the company began offering wireless security sensors in the 1980s.
[I] Jamming attacks are absolutely possible. As said before, with the right equipment and the right know-how, it’s possible to jam any wireless transmission. But how probable is it that someone will successfully jam their way into your home and steal your stuff？
[J] Let’s imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming system. First, a thief is going to need to target your home, specifically. Then, he’s going to need to know the technical details of your system and acquire the specific equipment necessary for jamming your specific setup. Presumably, you keep your doors locked at night and while you’re away. So the thief will still need to break in. That means defeating the lock somehow, or breaking a window. He’ll need to be jamming you at this point, as a broken window or opened door would normally release the alarm. So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s inside and searching for things to steal. However, he’ll need to do so without tripping the anti-jamming system, the details of which he almost certainly does now have access to.
[K]At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grab attack that makes up the majority of burglaries. They’re also only a single layer in what should ideally be a many-sided approach to securing your home, one that includes common sense things like sound locks and proper exterior lighting at night. No system is impenetrable, and none can promise to eliminate the worst case completely. Every one of them has vulnerabilities that a knowledgeable thief could theoretically exploit. A good system is one that keeps that worst-case setting as improbable as possible while also offering strong protection in the event of a less-extraordinary attack.
36. It is possible for burglars to make jamming attacks with the necessary equipment and skill.
37. Interfering with a wireless security system is similar to interfering with a conversation.
38. A burglar has to continuously jam the wireless security device to avoid triggering the alarm, both inside and outside the house.
39. SimpliSafe provides devices that are able to distinguish incidental radio interference from targeted jamming attacks.
40. Only a very small proportion of burglaries are committed by technical means.
41. It is difficult to crack SimpliSafe as its system keeps changing.
42. Wireless devices will transmit signals so as to activate the alarm once something wrong is detected.
43. Different measures should be taken to protect one’s home from burglary in addition to the wireless security system.
44. SimpliSafe’s device can send a warning to the house owner’s cellphone.
45. Burglars can easily get a security device’s frequency by Internet search.

项目经理小王目前正在负责—个小型的软件开发项目。—开始他觉得项目比较小，变更应该不多，流程也不需要太复杂，因此就没有制定项目变更管理计划，而是强调团队成员间的及时沟通来保证项目按照计划进行：根据项目经理小王的理解．所谓变更管理的主要目标就是保证项目能够按照计划进行，如果能够保证不发生超越项目进度计划、成本计划等控制范围外的偏差，就可以不用指定项目变更管理计划．就可以不用指定项目变更管理计划，以减少项目的工作量。而项目执行过程中对计划的微调根本不需要记录和管理，也不需要走项目变更管理流程。而且他认为如果所有项目变更都必简要向相关领导请示汇报，过程太复杂和麻烦，还不如由执行人员提出变更的方案，彼此讨论—直后来的更方便和快捷。
但是在项目进入集成测试阶段的时候，突然多了很多莫名其妙的问题出现。如在调试过程中。由于相关设计和记录的简化和不规范，造成了调试的困难，很难定位各个问题模块的错误；由于项目执行过程中。人员的调配替换，造成了文档记录的不—敢，导致后期人员阅读和理解方面的障碍。并且由于缺乏对开发过程的配置管理和控制，导致版本混乱，很难形成有效支持各模块集成的文档。另外，面目中很多细小的改动由于没有准确的记录，或者是根本没有记录．导致集成测试发现问题时，根本没有办法更改。小王对此也没有办法，不知道因为什么原因导致目前的项目状态，项目面临返工的危险。
