Cross-site scripting(XSS)

Know IT now

.

Cross-site scripting (XSS) is a type of computer security vulnerability. The expression “cross-site scripting” originated from the fact that a malicious web site could load another web site into another frame or window then use JavaScript to read or write data on the other web site. The definition gradually changed to mean the injection of HTML and JavaScript into a web page, causing confusion since the name no longer reflects the latest definition. By finding clever ways of injecting malicious scripts into web pages an attacker can gain elevated access privileges to sensitive page content, session cookies, and a variety of other objects.

The two words that you should keep in mind when you are writing are precision and clarity. Avoid long words and sentences. Remember you are writing to make your audience feel, think and be one with your story/essay and not to show them that you know your vocabulary! So choose the right word and make sure it fits into the context of what you are saying. After you have written your story or essay, read it and ask yourself what every word means. Long words like those ending in -ation,-lity, -ise, -isation, -ational tend to make your writing laborious and difficult to understand. Therefore use them as little as possible. Ask yourself if you can make your sentence shorter and crisper by removing these words.
Example: The student brought about the organisation of the school assembly.
Right usage: The student organised the school assembly.
Example: The usage of the words baffled many.
Right usage: The use of the words had many baffled.

Words like usage, methodology and functionality should be changed to a simpler method. Be specific in the choice of your words. Never use vague language.
Example: The newspaper industry made apparent significant financial gains this year.
Right usage: The newspaper industry made a lot of money OR the newspaper industry showed large profits.
