WHAT IS NETWORK SECURITY?

• 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

WHO IS CRACKER? 

• PERSON WHO  ENTER INTO OTHER’S SYSTEM AND VIOLET THE SYSTEM,DAMAGE THE DATA,CREATE HAVOC  IS CALLED CRACKER

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
• LIKE  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
