1.Introduction:
Ethical hacking also known as penetration testing (or) white-hat hacking,involves the same tool,tricks and techniques
that hackers use,but with one major deference that ethical hacking is legal.
2.Ethical hacking:
=>independent computer security professional breaking into the computer system.
=>Neither damage the target systems nor steal information.
=>Evaluate targets systems security and report back to owners about the vulnerabilities found.
3.Hacker's:
=>A person who uses computers to gain unauthorized access to data.
=>a person who uses computers to gain unauthorized access to data.
=>A person who enjoys learning details about of a programming language's or systems.
=>A person who enjoys actually doing the programming rather then just theorizing about it.
=>A person capable of appreciating some one else's hacking.
=>A person who pick up programming quickly.
4.Types of hacking:
*Black-hat hacker's
*White-hat hacker's
*Grey-hat hacker's
1-Black-hat hacker's:
=>A black-hat hacker's or crackers individuals with extraordinary computing skills,resorting to malicious or destructive activities.=>That is black-hat hacker's use their knowledge and skill for their own personal gains probably by hurting others.
2-White-hat hacker's:
=>A white-hat hacker's are those individuals professing hacker skills and using them for defensive purposes.=>This means that is white-hat hacker's use their knowledge and skill for the good of other and for the common good.
3-Grey-hat hacker's:
=>These are individuals who work both offensively and defensively at various times.
=>We cannot predict their behavior.
=>Sometimes they use their skills for the common good while in some other times he used them for their personal gains.
5.Hacking process:
*Foot printing
*Scanning
*Gaining access
*Maintaining access
1-Foot printing:
*Whois lookup
*NS lookup
*IP Lookup
2-Scanning:
*Port scanning
*Network scanning
*Finger printing
*Fire walking
3-Gaining access:
*Password attacks
*Social engineering
*Viruses
4-Maintaining access:
*OS backdoors
*Trojans
*Clear tracks
6.Why do we need ethical hacking:
Protection from possible external attacks
*Social engineering
*Automated attacks
*Denial of service (DOS)
*Viruses,Trojan horses and worm's
*Accidental breaches in security
*Organization attacks
7.Required skills of an ethical hacker:
Microsoft: Skills in operation,configuration and management.
Linux: Knowledge of Linux/Unix: Security
Setting,configurations and services.
Firewalls:configurations,and operation of intrusion detection systems.
8.Required skills of an ethical hacker:
Routers:knowledge of routers routing protocols and access control lists.
Mainframes.
Network protocols:TCP/IP;how they function and can be manipulated.
Project management:leading,
planning,organizing and controlling a penetration testing team.
9.What do hackers do after hacking:
=>Patch security hole.
***The other hacker's can't intrude***
=>Clear logs and hide themselves.
=>Install root kit (backdoor).
***The hacker who hacked the system can use the system later***
***It contains Trojan's and virus so on***
=>Install irc related program.
***Identd,irc,bitchx,eggdrop,bnc***
10.What do hackers do after hacking:
=>Install scanner program
***mscan,sscan and nmap***
=>Install exploit program.
=>Install denial of service program.
=>Use all of installed programs silently.
11.Advantage's:
=>"To catch a thief you have to think like a thief"
=>Helps in closing the open holes in the systems network.
=>Provides security to banking and financial establishments.
=>Prevents website defacement.
=>An evolving technique.
12.Disadvantage's:
=>All depends upon the trustworthiness of the ethical hacker.
=>Hiring professional is expensive.
13.Future Enhancements:
=>As it an evolving branch the scope of enhancements in technology is immense.
=>No ethical hacker can ensure the system security by using the technique repeatedly.
=>More enhanced softwares should be used for optimum protection.
14.Conclusion:
=>In the preceding section we saw the methodology of hacking,why should we aware of hacking and some tools which a hacker may use.
=>Now we can see what can we do against hacking or to protect ourselves from hacking.
=>The first thing we should do is to keep ourselves updated about those softwares we and using for official and reliable sources.
=>Educate the employees and the users against black-hat hacking.
