If you downloaded it from the Internet or LAN, then you should not run the operation of macros. Perhaps the document contains a virus. Install the “patch” to your operating system and installed programs. Many support the automatic update (for example Windows XP or Linux Ubuntu). This protects you against viruses that spread by errors in the program or operating system. Network Attacks phenomenon is less common than viruses, but more dangerous. The purpose of a network attack can be misappropriation of information, or blocking of a single computer or an entire subnet. Network attacks are usually perpetrated by well-trained hackers, although cases are cases when it engaged in “kids” just for fun.
There are plenty of network attacks and their classifications, I will describe only the most famous. Brute force (brute force) is a method of overcoming the password protection. The idea is that the password is chosen enumeration of all possible variations. Can be used both on the network, and on the local machine. Sometimes brute force applied with the use of dictionaries. It is therefore necessary to use resistant to password guessing. And of course the password should not be meaningful word. Highly desirable to use numbers with letters, as well as uppercase and lowercase letters. Example: in case of burglary at a rate of 10,000 combinations per second (using the Latin alphabet in one case + digits) speed guessing the password of 4 characters 20 seconds of 8 characters in about 10 months.
Today it has become fashionable for people to write and publish their books. How much will it cost? People who want to publish a book asking this question in the first place. It’s a simple question, but does not have lung answer. It’s like asking how many home is worth. Who can give a definite answer, most likely you will be asked leading questions: “Do you want a house had two stories or one? 3 bedrooms or 2? Basement or attic? Brick or wood? “Just as the house price, the cost of your book depends on a dozen or more variables. To estimate the costs of publishing, you should consult with local centers of printing. Get information about the publication of the book, at least among the three companies, as prices can vary greatly. Before you can bring your project in the printing, you need to know three important facts about your manuscript: 1. Exactly how many pages (bands) in the manuscript. You must take into account the finished project, including mock-ups pages of photographs, entry pages and applications. 2. Approximately how many books you want to print (ie, circulation). 3. Think about the type and quality of paper, font size and style, the number of photos. All these factors will included in the cost of printing the book. Spend some time browsing the books in libraries or bookstores to take some ideas about what you want, namely, the exterior design. You write a book for reading, so this book should appeal to readers. Most of the commercial books in bookstores are well designed and therefore attractive to the reader. Cover should be attractive to the reader’s eye. For example, the fine print on the page margins are too difficult for the average view for comfortable reading. Use large fonts normal width. When asked to use high-quality printing paper. Standard sheets will become dirty and worn out. Be generous with your photos. People usually look for pictures in the books before they read words. Black and white pictures, not worse, than color, and much cheaper. Photos can be scattered throughout the text, or collected in a separate section in the middle or end of the book. However, photographs should be used to illustrate the narrative, rather than detract from it. Too many photos randomly scattered throughout the text can distract the reader, causing to lose interest in narrative. If you create a digital version of your manuscript, make sure to scan the photos selected parameters at least 300 dpi. If you have a lot of pictures, this will add little to the cost of books. Thus, we can summarize that the price of printing the book often depends on: 1) the number of bands (pages) in a block of the book, 2) the color of the block and cover, 3) the number of publications (circulation), 4) quality of the paper (density, gloss or matte), 5) colorful cover (stamping, laminating, etc.), 6) method of binding (soft or hard).
