INTRODUCTION TO ETHICAL HACKING : 

INTRODUCTION TO ETHICAL HACKING An Ethical Hacker is an expert hired by a company to attempt to attack their network and computer system the same way a hacker would. Ethical Hackers use the same techniques and tactics as those used by illegal hackers to breach corporate security systems. Most people think of hacker as a computer vandals .But, call a real hacker a criminal and believe me ,he would do more than lose his temper .Hackers are not computer criminals .Why do most people think of hackers as criminals??The media is responsible for this erroneous assumption.

How Does a Hacker Work??? : 

How Does a Hacker Work??? Data:-It is the collection of facts and figures. Information:-After processing data(such as formatting and printing), output data can again be perceived as information.

Intelligence:-It is an umbrella term describing a property of the mind including related abilities, such as the capacities for abstract thought, understanding, communication, reasoning, learning, learning from past experiences, planning, and problem solving. The complexity increases from data to intelligence.it is easier to get data but quiet difficult to extract information from them and apply our intelligence upon them.

DESKTOP AND SERVER SECURITY : 

DESKTOP AND SERVER SECURITY Window Security:- 1st level 2nd level 3rd level Registries:- The registry is the core of the operating system .If we mess with it, we may need to reinstall our operating system, so keep installing disk ready. But if we do conquer the registry, we can control the whole computer. Following are the five registries of any system HKEY_CLASSES_ROOT HKEY_CURRENT_USER HKEY_LOCAL_MACHINE HKEY_USER HKEYY_CURRENT_CONFIG Ports and Services Vulnerabilities in windows CORRECTIVE MEASURES
