PPPPT ON ETHICAL HACKING212313213213213213

In today's interconnected world, cybersecurity is paramount. This in-depth presentation demystifies the critical practice of ethical hacking, distinguishing it from malicious hacking and highlighting its crucial role in protecting digital assets. It provides a comprehensive overview of how "white hat" hackers use the same tools and tactics as cybercriminals, but with proper authorization, to uncover and fix security vulnerabilities. Ideal for aspiring cybersecurity professionals, business owners, and IT students, this presentation reveals how a proactive, offensive-minded security strategy is the best defense.

3. Q) What is Hacking ? Hacking means finding and exploiting weaknesses in computer systems. Q) What is Ethical Hacking ?  Ethical Hacking is legal hacking done with permission to improve security. Ethical llegal Introduction to Hacking

4. Types of Hackers:

5. White Hat Hacker: Perform Ethical Hacking Have knowledge of hacking and hacker toolset Locate security weaknesses and implement counter-measures Also known as Penetration Tester Focus on securing and protecting IT systems

6. Black Hat Hacker: Perform unethical hacking Are criminal hackers or crackers Use their skills for illegal or malicious purposes Focus on Security Cracking and Data Stealing

7. Grey Hat Hacker: Sometimes acts legally and sometimes not Do not hack for personal gain Do not have malicious intentions May occasionally commit crimes Are hybrid between White Hat and Black Hat Hackers

8. Classification of Hackers:

9. Steps Performed by a Hacker:

10. This is the first step in hacking, also known as footprinting . The hacker collects as much information as possible about the target (organization, system, or individual). Reconnaissance: Scanning: After gathering initial information, the hacker scans the target system to identify vulnerabilities. Tools are used to detect open ports, running services, and security loopholes.

11. This is the actual attack phase. The hacker uses the discovered vulnerabilities to enter the system. Gaining Access: Clearing Tracks: To avoid being detected, the hacker erases all traces of their activity. Methods :- Deleting log files, Hiding malicious programs, Using encryption and anonymization tools

12. Denial of service Interception Manipulation Masquerading Repudiation Security Threats:

13. Acts as a middleman between user and internet. Hides user’s IP for privacy. Can cache data to improve speed. Used for filtering and access control. Helps bypass geo-blocks/censorship. Advantages: Security, anonymity, faster browsing. Disadvantages: Slower speed, trust issues. Proxy Servers:

14. Proxy Servers: Internet Proxy Server Router/Switch LAN Wireless connection

15. Confidentiality Integrity Availability Use antivirus. Proper logout after use of email id. Don’t open spam. Password protected admin account. Security:

16. Confidentiality Integrity Availability Use antivirus. Proper logout after use of email id. Don’t open spam. Password protected admin account. Security:

17. Protects Data & Privacy: Safeguards sensitive information from breaches and cyber theft. Builds Trust: Clients and customers feel safer knowing security is tested. Prepares for Attacks: Organizations become aware of real-world hacking techniques. Skill Development: Enhances technical expertise in networking, cryptography, and system security. Benefits of Ethical Hacking:

18. Restricted Scope: Ethical hackers work within defined boundaries; not all vulnerabilities may be tested. High Cost: Skilled professionals and advanced tools can be expensive. Dependence on Tools: Automated tools may miss zero-day vulnerabilities. Human Factor: Insider threats and social engineering may still bypass defenses.Time -Consuming: Complete testing of large systems requires significant time Limitations of Ethical Hacking:

19. Growing Demand: Cybersecurity jobs are increasing due to rising cyberattacks. Job Roles: Penetration Tester, Security Analyst, Cybersecurity Consultant, Forensic Expert. Industries Hiring: IT companies, government agencies, banks, defense, e-commerce, cloud providers. Certifications: CEH (Certified Ethical Hacker), OSCP, CompTIA Security+, CISSP. Career Scope in Ethical Hacking:

20. AI & Machine Learning: Ethical hackers will use AI to predict and detect threats. Cloud Security: Increasing need to secure cloud services and data. IoT & Smart Devices: More connected devices = more vulnerabilities to secure. Global Demand: Every sector needs ethical hackers, ensuring long-term career stability. Evolving Threats: As cybercrime grows, ethical hacking will become a critical profession worldwide. Future of Ethical Hacking:

21. Conclusion: Ethical hacking is a powerful tool to safeguard digital assets. It helps organizations identify vulnerabilities before attackers exploit them. Though it has limitations, its benefits outweigh the risks. Offers excellent career opportunities in cybersecurity. With the rise of AI, cloud, and IoT, ethical hacking will remain essential for the future.
