Hide your Identity
Before you venture online, keep the following facts in mind:
· Someone on the Net can make money by selling your personal data.
· Every time you go online, you give someone new information—however small a piece it may be—about your preferences.
· Some data collectors are not content to wait for you to come to them and may try to trick or steal more information from you.
We can call these the Basic Rules of Personal Information, and they hold true for everyone who uses the Internet, from your Uncle Sid to Larry Ellison.[1]Your good name and every iota of data about you are for sale. Since you're not getting a cut of the profits (at least, most people aren't),[2]it's best to keep your private information to yourself. After all, once it's out of your hands, you have no control over who gets it and how they use it.
Protect your IP Address
Like the number and street name of your real-world address, a computer's IP address[3]tells others where and how to find the computer online. This identifier is composed of four numbers, each between 0 and 255, separated by periods (for example, 123. 123. 23. 2). Every Web site and electronic device connected to the Internet must possess a unique IP address; that is, no two devices can have the same IP address at the same time.
If spammers or hackers manage to get your IP address, they can assault your PC with viruses or even hack directly into it to steal your personal data. You can put up dedicated hardware or software firewalls and install antivirus programs on every node in your network, but, given enough time and resources, a determined hacker can break into almost any computer.
You should guard your IP address as carefully as you would guard your full name and street address. Neither your browser nor Windows itself allows you to hide your IP address from the outside world, but some third-party software takes care of this problem. Freedom,[4]from Zero-Knowledge Systems, masks your true IP address from the real world by routing all your Internet data through the Zero-Knowledge network. This program can stump even Web bugs.
If you use a dial-up connection, you're less at risk because your IP address changes with every session. But if you have an always-on connection, such as DSL or cable, you probably have a static or unchanging IP address. A static IP can leave you vulnerable to repeated scans and attacks. On the other hand, if you get a different IP address each time you connect to the Internet—a dynamic IP address—you can present a moving target for the hackers. If you' re privacy conscious, ask your ISP[5]for a dynamic IP address. Intruders will have a much harder time finding your computer time and time again if your address isn't constant.
Cookies Keep Track
But Web sites also use other technologies to track you down and trace your movement online. Cookies are small data files that the Web sites you visit can store in your browser's cookie file to track your path across the Web or record your user preferences. Most cookies have useful purposes. For example, if you register to view a specific Web site (such as the New York Times on the Web), the site can plant a cookie on your computer so that, thereafter, you won't need to enter your username and password to access the site. There are two kinds of cookies, persistent cookies, which remain on your computer even if you shut it down, and per-session cookies, which are often used to store the contents of a shopping cart and won't be saved once you power off your PC.
The threat cookies present isn't from the depth of the information they can reveal; cookies don't permit hackers' unfettered access to your private files, for instance. The threat is a small but long-term erosion of your privacy. Most sites record cookies every time you click a new link within the site and can later find out which pages you read and how long you lingered. Such information may be very useful to marketers who mine it for details on your habits and likes or dislikes. Over time, these minute data fragments can help companies build a profile of you, which they could sell to yet more aggressive marketers.
Bugs Do it Better
If you delete the cookies regularly or configure your browser not to accept them, snoopy sites can't collect enough data to profile you. That's why some companies use Web bugs as a user-tracking backup if cookies don't work. Here's how Web bugs work: these tiny graphics, sometimes just a pixel high and a pixel wide, are the same color as a Web page's background. Any time you visit a site, the site must have your IP address before it can load any Web graphic file (including a Web bug), and, with your IP address in hand, the machine that hosts the Web bug can log your address for the duration of your session.[6]Even with cookies blocked, bugs let sites track users surreptitiously. In many cases, the tracking may be benign—a site monitoring how popular a particular page is—but it isn't always just the site that uses a Web bug. Commercial sites with banner ads have discovered that ad banner companies themselves, such as DoubleCliek,[7]may use Web bugs to track the traffic on the sites that host their ads. So Web bugs can open you up to unwanted profiling, and (if the Web bug loads after a user fills in a Web order form, for example) possible junk mailing.
Stop Hostile Apps
Cookies aren't inherently malicious, but the ubiquitous little files inhabit your hard drive (if you use Internet Explorer, for instance, the cookies reside inside your C:\ Windows\Cookies folder) and identify you via a string of numbers and letters (called a unique identifier) to the Web site or company that placed the cookie there. For instance, companies such as DoubleClick, Adbureau. net,[8]or Link Exchange[9]that provide advertising to Web sites can plant a cookie on your hard drive when you are reading one site (for example, Amazon. com[10]) and then read that same cookie when you surf to a different DoubleClick-served site (for instance, CNN. com[11]). That's how the company tracks you across multiple sites.
Take a Bite out of Cookies
Fortunately, your browser makes it easy to disable cookies: in Internet Explorer 5. x,[12]click Tools ＞ Internet Options, then choose the Security tab. Click the Earth icon labeled Internet, then click the Custom Level button near the bottom of the window. In the Security Settings window that opens, scroll down to the section labeled Cookies. To keep your browser from automatically planting cookies on your PC, select the Disable or Prompt option next to "Allow cookies that are stored on your computer" (in other words, the persistent cookies we mentioned earlier). It's generally OK to leave the per-session cookies enabled; these are the cookies that remember what's in your shopping cart when you use a Web store.
In Netscape, click Edit ＞ Preferences and select the Advanced item in the left pane. Here, you can opt to block all cookies or to decide on a site-by-site basis. We recommend that you pick the second option and allow your browser to use cookies for some sites. That way, you can exercise a measure of control over your information and still take advantage of the cookie conveniences. If you're truly paranoid, however, you may want to disable all cookies even if it prevents you from, say, shopping efficiently online.
If you're curious about how many sites set cookies, check the "Warn me before accepting a cookie" box, and Navigator will pop up a dialog box each time a site tries to set a cookie. (Internet Explorer still lacks such an option. ) We recommend that you try this for only a short time; the sheer volume of cookie request dialogs will likely drive you crazy.
Be Selective
Simply disabling cookies may not work for you, however. Internet Explorer doesn't let you block cookies sent to advertising companies while permitting cookies from the site you're visiting; it's all or nothing. Blocking all cookies eliminates the timesaving benefit of user preferences on free customizable news sites such as My Yahoo. If you use IE and want to pick and choose which sites are allowed to plant cookies on your hard drive, try the handy freeware CookieWall[13]from AnalogX. CookieWall runs in your System Tray, silently monitoring your Internet Explorer cookie file every minute or so and allowing you to pick and choose which cookies to permit. When the program encounters a cookie that it hasn't seen before, a dialog box pops up to ask you what to do with cookies from this site—handy if, say, you register to use My Yahoo and don't want to have to enter your username every time you load the page.
Connection Protection
If you use a high-speed connection such as DSL or cable, consider downloading ZoneAlarm,[14]CNET's[15]favorite free personal firewall. Firewalls not only keep hostile apps from entering your PC from the outside, they also block hidden or unknown software on your PC (the sort a virus could install) from connecting to the Internet without your knowledge and giving away your valuable information.
To find out how secure your connection is, go to Steve Gibson's Shields Up[16]site and get a free test of your security. Shields Up performs many of the same tests hackers use to probe your computer for vulnerabilities and provides you with a summary assessment of your PC's security and what you need to do (if anything) to make yourself less vulnerable. Gibson's scan can tell you if the back door program is running but not if it has been (or is being) used. But a little information goes a long way. If you know the Trojan is there, you can work to get rid of it.

Subject: Customer Complaint
To Whom It May Concern,
I have trusted the Shoe People to protect the feet of my employees for over ten years now. I recently purchased a few pairs of boots from your company for my crew. Though my men were initially satisfied with the boots, the soles began to fall apart on them after just twelve weeks. This was extremely surprising considering they came with a six year warranty. The boots are unsafe to wear because my men are pouring hot concrete. Please respond as soon as possible with instructions on how I can return the boots and receive a refund.
Thank you.

Subject: RE: Customer Complaint
Dear Mr. Trimbald,
Thank you for your e-mail concerning the poor quality of our rubber soled black workboots. A representative will be by your office next week to pick up the damaged boots. We apologize for any inconvenience this has caused you and your crew. Along with five new pairs of workboots for your crew (we included one extra pair), we have enclosed a free year's supply of sole protector spray. In our retail stores, this spray is always recommended to buyers who work on heated floors. This should have been brought to your attention at the time of your initial order (received by telephone on October 12, 2007). Please excuse our oversight. To date we have had no complaints about these workboots from customers who have used the protector spray. However, should you use the spray and find that you are still unsatisfied with the boots, please return the boots and spray for a full refund. Thank you for supporting The Shoe People. Have a Happy New Year.
Sincerely,
Stan Mason, President
Which company was unsatisfied？
A．Stan Mason's company
B．The Shoe People

No matter which software or methodology is used on the back end, establishing a career portal starts out with one common action: setting up a link or a button on the corporate web site typically on the home page, labeled "careers" or "jobs". Clicking that link or button transports visitors into the recruiting application, which often has the same look and feel of the corporate web site.
Web recruiting software typically falls into three basic categories, although they overlap because they all offer additional functions beyond posting jobs. For example, most also include applicant tracking and reporting functions.
The first option: Take advantage of the web recruitment function included in HR modules of ERP system. Steve Gilloo]y, senior consultant for New York-based Mercer Human Resources Consulting once said that when a company has purchased an HR suite, it is just a matter of turning on the web-based front end and everything from the configuration of the site to the creation of the supporting data and the tracking of applicants is just an extension of the core ERP system.
Now comes the second option. Instead of using that built-in function, you may choose to purchase a specialized best-of-breed recruitment application from a software vendor. Some companies specialize in a particular industry, and others target businesses by size. Most of these packages can operate as either a stand-alone product or can link to the company's HR management system (HRMS). For example, BearingPoint Inc., an international business and, technology consulting firm based in McLean, Va. uses software from Recruitmax of Ponte Vedra Beach, Fla, to drive recruiting on its corporate website as well as on its internal career portal and its alumni network portal. Through these sites, people can apply for jobs themselves or refer to others. To get information on new hires from the Recruitmax application into the company's HRMS from PeopleSoft of Pleasanton, Calif., BearingPoint created a customized interface that sends an extensible markup language (XML) feed every hour to a helper application that sits on the PeopleSoft side of the fence.
A third option is to use an application service provider (ASP). Many best-of-breed vendors offer their software on such a hosted basis. Also, recruiting Web sites such as Monster. com host corporate career sites. An ASP is easier to set up and operate, and this method may increase security. Some companies don't want potential applicants to have access inside the firewall, so they have someone else host the career portion of their website.
If you go with the ASP model, typically you are looking at a fixed duration contract, make sure you understand what will happen at the end of the contract or if the vendor is acquired by another company, and if, when you do your due diligence, the vendor looks like it poses some risk, make sure a copy of the source code is put in escrow.
