- 3. INTRODUCTION Ethical hacking is also known as penetration testing, instruction testing or red teaming It is Legal Permission is obtained from the target Part of an overall security program Identify vulnerabilities visible from Internet at particular point of time Hacker Cracker
- 4. TYPES OF HACKERS White Hat Hacker Good guys Don’t use their skill for illegal purpose Black Hat Hacker Bad guys Use their skill maliciously for personal gain Grey Hat Hacker It is a combination of White hat n Black Hat Hackers Goal of grey hat hackers is to provide national security

- 8. SECURITY TYPES Broadly we can divide security in three divisions 1.System security 2.Data Security 3.Network Security System security is least consider nowadays also when we have maximum number of hackers and crackers.
- 9. SYSTEM SECURITY System security means securing a system from unauthorized access by the person who can physically access it. System security is further divided into two divisions 1. System accessible Security 2. Data accessible Security
- 10. SYSTEM ACCESSIBLE SECURITY System accessible security means restricting someone to access the system completely, it can be referred as OS level security. Eg: Provide user password in the system
- 11. DATA ACCESSIBLE SECURITY When we give permission to a user to access only certain files and folders in a system then it is consider as the Data Accessible Security. We can achieve data accessible security by many ways. Some of the ways are:- 1) Encrypting Hard disk 2) Hiding Folders 3) By locking folders
- 12. KEYLOGGERS, ANTI-KEYLOGGERS Keyloggers are a software or hardware which records the screenshots or keystrokes without the knowledge of user. Types of keyloggers: 1.SOFTWARE KEYLOGGERS 2.HARDWARE KEYLOGGERS Hardware key loggers can be detected by carefully observing the port but to prevent system from software keyloggers, we need to install anti keyloggers.

- 14. TIPS FOR SECURING SYSTEM DATA AND SYSTEM Install and Use Anti-Virus, firewalls & Anti key logger Programs While installing OS like Windows XP give admin password. Use Care When Reading Email with Attachments and following links. Install and Use a Firewall Program Make Backups of Important Files and Folders Change passwords Use Care When Downloading and Installing Programs Install and Use a Hardware Firewall Install and Use a File Encryption Program and Access Controls Safeguard your Data Real-World Warnings keep you safe online.

- 19. CONCLUSION We should pay maximum attention towards our system security and we can do the same by remembering this line “Treat your password like you treat your toothbrush. Never give it to anyone else to use, and change it every few months & most importantly use SYSKEY”
