How to protect from different internet attacks

[Felix46]

I need some protection techniques from the various types of attacks from internet. Like what does a zombie do and how to get protected from it. The other thing is raw force hacking and phishing in the same manner. I need some detailed information on the same. What does this attacks actually do in the system and how to prevent them.

A zombie is a PC almost certainly poorly protected and which has been contaminated by a virus or worm. This program allows a malevolent hacker to take remote control of the PC and use it to send mail, attack other machines, etc. An attacker can trigger a DOS attack if it has control of a large number of zombie machines.

The raw force hacking is to go there in the most basic and most atrocious manner on a form of identification. The principle is to locate a login, preferably with elevated privileges on the target system and try all possible passwords. There are mainly 2 methods. The first is based on a dictionary of passwords more frequently while the second pass through all possible combinations. This attack can come from one or more machines attacking. By counting the number of failed login attempts. Reached a predefined threshold, the account is disabled. If the owner wants to reactivate it passes through a reactivation process with email confirmation you can protect yourself.

Phishing is a method or procedure used by hackers to acquire secret or private information in sequence from the users (such as bank information, for example). This method is not necessarily very technical in itself, it relies mostly on Social Engineering. To do this, hackers imitate a trusted organization (bank type), and send mails to victims in claiming such and such problems, and fill a form with sensitive information.

Other techniques more advanced than the form by mail, exist as the theft of content. In this case, hackers created a website, identical in all respects with the official website. The email is then simply click on a hyperlink redirecting this famous site, where we therefore ask the user to enter confidential information which will be obviously be recovered by the attacker.

First you must know that no bank or using and influencing data confidential request for information by mail. Then, you should never click on a link in an email, it is preferable to refer oneself address in the address bar. When entering sensitive information (eg banking), be sure to check that the protocol is https, and also check the validity and origin of the certificate used. Some tools and utilities (eg toolbar) for Internet browsers exist, to protect themselves from phishing including checking the URL.
