- Security is much larger than just packets, firewalls, and hackers. Security includes:
–Policies and procedures
–Liabilities and laws
–Human behavior patterns
–Corporate security programs and implementation
–Technical aspects- firewalls, intrusion detection systems, proxies, encryption, antivirus software, hacks, cracks, and attacks
- Understanding hacking tools and how attacks are carried out is only one piece of the puzzle.
Hacking
- THE PROCESS OF ATTEMPTING TO GAIN OR SUCCESSFULLY GAINING,UNOTHORIZED ACCESS TO COMPUTER RESOURCES FOR THE PURPOSE OF HELP OR SECURE SYSTEM IS CALLED HACKING

WHO IS HACKER?
HACKER IS NOT CYBER CRIMINAL BUT HE IS THE VERY INTELLIGENT PERSON WHO USES HIS KNOWLEDGE IN CONSTRUCTIVE MANNER TO SECURE SYSTEM & NEVER DAMAGE DATA
HE KNOWS ALL ABOUT THE OPERATING SYSTEM & DIFFERENT HOLES IN THE SYSTEM

DIFFERENCE BETWEEN HACKER & CRACKER
- HACKER’S PROGRAMS TO CHECK INTIGRITY OF OTHER PROGRAMS.THUS WHEN HACKERS CREATE PROGRAM IT AUTOMATICALLY CHECKS REMOTE MACHINE SECURITY STRUCTURE
- THEY ALWAYS DO CONTRUCTIVE WORK
- CRACKERS RARELY MAKE THEIR OWN PROGRAM .INSTEAD ,THEY STEAL TOOL,PROGRAMS FROM OTHERS
- CRACKERS CREATES NOTHING & DESTROY MUCH
WHICH OPERATING SYSTEM HACKER USE
- SUN
- UNIX
- MICROSOFT
SUN
HACKERS Use EITHER SOLARIC X86 OR SCO AS A PLATFORM.
THIS IS BECAUSE THESE PRODUCTS ARE LICENSED WARE & THEY CAN EASILY BE OBTAINED.
UNIX
- POPULAR PLATFORM BECAUSE THEY REQUIRED A LOW OVERHEAD.
- WE CAN RUN LINUX ON A PALTRAY 386 AND GAIN GOOD PERFORMANCE.
- THIS IS REASONABLE.
MICROSOFT
- THIS SUPPORTS MANY SECURITY TOOLS THAT CAN BE USED TO ATTACK REMOTE MACHINE.
- IT HAS ADVANCED TOOLS FOR NETWORKING AS WELL.
WHY DO PEOPLE HACK ?
- JUST FOR FUN.
- SHOW OF THEIR KNOWLEDGE.
- HACK OTHER SYSTEM SECRETLY.
- DESTROY ENEMY’S COMPUTER NETWORK DURING THE WAR.
- FOR PROFIT PEOPLE PAYS A CRACKER.
- CRACK FOR SAKE OF CURIOCITY.
THE PSYCOLOGY OF HACKERS
- ALL INFORMATION SHOULD BE FREE.
- ACCESS TO COMPUTER SHOULD BE UNLIMITED AND FREE.
- IT CAN CHANGE LIFE FOR BETTER.
- IT CAN CREATE BEAUTY ON COMPUTER.
TYPES OF HACKING
THERE ARE MANY TYPES OF HACKING
LIKE
- PASSWORD HACKING
- SOFTWARE HACKING
- NET HACKING
PASSWORD HACKING
TWO TYPES
1.BRUTE FORCE
- IN THAT CASE HACKERS TRY OUT ALL THE COMBINATION OF ALL KEYBOARD LETTERS .IT HAS GRATER SUCCESS BUT IT TAKES LONG TIME
2.DICTIONARY BASED
- IN THAT THEY ARE USE PREDEFINE PASSWORD.IT IS UNSUCCESSFUL METHOD
SOFTWARE HACKING
- IN THAT HACKERS CHANGES THE LOOK & EXCUTION WAY OF THAT SOFTWARE
- CHANG THE DEMO VERSION INTO FULL VERSION BY DECODING THE SOURCE CODE
IP ADDRESS
- IP ADDRESS IS THE ADDRESS OF YOUR COMPUTER IN THE INTERNET
- IT IS UNIQ
- LIKEÂ 192.168.23.45
PORT
- IT IS NOT PHYSICAL PORT BUT IT IS LOGICAL PORT IN YOUR COMPUTER
- IT IS JUST LIKE HOLE ONTO THE SYSTEM.THROUGH HACKER CAN ENTER
- THERE ARE THOUSANDS OF PORTS INTO COMPUTER
- THE PERTICULAR SERVICE IS RUNNING ON PERTICULAR PORT
- LIKE
  PORT 21 : FTP
   PORT 23 : TELNET
   PORT 80 : HTTP
   PORT 25 : MAIL
HACKING TOOLS
THERE ARE MANY TOOLS ARE AVILABLE
- SCANNERS
- TELNET
- FTP
- LAN WATCH
SCANNERS
- IT IS NOT A PHOTO SCANNER
- SCANNER IS PROGRAM THAT AUTOMATICALLY DETECTS SECURITY WEAKNESS IN REMOTE HOST
- PORT SCANNERS ARE USED IN HACKING
- PORT SCANNER CAN GIVE THE WHOLE LIST OF OPEN PORT ON THAT SYSTEM AND WHICH SERVICE IS RUNNING ON THAT
- IT CAN USE ALMOST ALL OPERATING SYSTEM
- EX. SATAN,NMAP
TELNET
- TELNET IS ULTIMATE HACKING TOOL
- IT IS TERMINAL EMULATION PROGRAM THAT ALLOWS US TO CONNECT TO REMOTE SYSTEM
- YOU HAVE TO FOLLOW THIS STEP TO USE TELNET
C:\WINDOWS\TELNET [IP ADDRESS] PORT
FTP
- FTP IS ONE TYPE OF PROTOCOL BUT SOME TIME IT IS USED AS HACKING TOOL
- PORT 21 FOR THE FTP
- FOR CONNECTING FTP WE NEED SOME FTP S/W KNOWN AS FTP CLIENT
- FOR CONNECTING FTP SERVER YOU HAVE TO HAMMER THAT SERVER
- COMMAND:
C:\WINDOWS\FTP [IP ADDRESS]:PORT
