How do I protect myself from hackers

The term hacker was once used to describe a clever programmer. Today, it’s applied to those who exploit security vulnerabilities to break into a computer system. You can think of it as electronic burglary. Hackers regularly break into both individual computers and large networks. Once they have access, they may install malicious programs, steal confidential data, or perhaps use compromised computers to distribute spam.

Today’s computer software is very complex, comprised of thousands of lines of code. Since software is written by humans, it’s hardly surprising that they contain programming mistakes, known as vulnerabilities. These loopholes are used by hackers to break into systems; they are also used by authors of malicious code to launch their programs automatically on your computer.

How the Web Spoofing Attack Works

URL Rewriting

STEP I
# A Phisher could insert a malicious script inside a product review to attack the user.

# The Script would modify the host site so that the user believes he/she is interacting with secure site. this technique is also called as “Cross-Scripting.”

STEP II
# This done by using encoded characters to hide the destination address of a link.
Ex-“abc” = "abc”

Secure your wireless network from hacker

If your wireless network is not secure, a hacker can easily intercept the data you send and receive, or access files saved on your computer – all from the comfort of their own sofa.

Why is it necessary to secure my wireless network?

These days, most computers are wireless-enabled: they let you connect to the Internet without a physical network cable. The major benefit, of course, is that you can use your computer anywhere in the house or office (as long as it’s within range of your wireless router). However, there are potential risks involved in wireless networking - unless you make your network secure:
A hacker could intercept any data you send and receive;
A hacker could get access to your wireless network;
Another person could hijack your Internet access.

Computer crime - Forms of Attack

The growing economic value of information, products, and services accessible through computer systems has attracted increased attention from opportunistic criminals. In particular, the many potential vulnerabilities of online systems and the Internet have made computer crime attractive and pose significant challenges to professionals whose task it is to secure such systems.

The motivations of persons who use computer systems in unauthorized ways vary. Some hackers primarily seek detailed knowledge of systems, while others (often teenagers)
seek “bragging rights.” Other intruders have the more traditional criminal motive of gaining access to information such as credit card numbers and personal identities that can be used to make unauthorized purchases (see identity theft). Computer access can also be used to intimidate (see cyberstalking and harassment), as well as for extortion, espionage, sabotage, or terrorism (see cyberterr orism).
