10. Hacking Process Explanation
• Footprinting:
Footprinting is the technique of gathering
information about computer systems and the
entities they belong to.
• Scanning:
Port scanning is a common technique used by a
penetration tester to find out the open doors, In technical
terminology port scanning is used to find out the
vulnerabilities in the services listing on a port.
11. Enumeration:
Enumeration is the first attack on target network, enumeration is the
process to gather the information about a target machine by actively
connecting to it.
Attack And Gaining Access:
In computer and computer networks an attack is any attempt to
destroy, expose, alter, disable, steal or gain unauthorized access to
or make unauthorized use of an asset.
This is the phase where the real hacking takes place. Vulnerabilities
discovered during the reconnaissance and scanning phase are now
exploited to gain access. The method of connection the hacker
uses for an exploit can be a local area network (LAN, either wired or
wireless), local access to a PC, the Internet, or offline. Examples
include stack-based buffer overflows, denial of service (DoS), and
session hijacking. These topics will be discussed in later chapters.
Gaining access is known in the hacker world as owning the system.
12. Escalating Privilages, Covering Tracks & and creating Backdoors:
Once hackers have been able to gain and maintain access, they
cover their tracks to avoid
detection by security personnel, to continue to use the owned
system, to remove evidence of
hacking, or to avoid legal action. Hackers try to remove all traces of
the attack, such as log files
or intrusion detection system (IDS) alarms. Examples of activities
during this phase of the
attack include steganography, the use of tunneling protocols, and
altering log files.
13. Some tips to protect from Hackers!
• Keep Antivirus in PC and Keep it Up-dated.

• Choose Cryprtic Password for accounts (use
special symbols,numbers,words)

websites.
• Download OS updates.
• Keep Anti-spyware in your computer.
• Use Virtual Keyboard when online shoping.
