Ethical Hacking: A Comprehensive Guide
1. Definition:
Ethical hacking, also known as penetration testing or white-hat hacking, involves authorized professionals attempting to exploit vulnerabilities in computer systems, networks, or applications to identify and rectify security weaknesses.
2. Objectives:
- Identifying Weaknesses: Ethical hackers aim to discover vulnerabilities that malicious hackers could exploit.
- Security Enhancement: By pinpointing weaknesses, organizations can strengthen their security measures.
- Risk Mitigation: Ethical hacking helps in reducing the risk of unauthorized access, data breaches, and other cyber threats.
3. Key Concepts:
- Authorization: Ethical hackers must have explicit permission to test a system or network.
- Legality: Activities are conducted within the legal framework to ensure ethical boundaries are not crossed. Ethical hacking course in Pune
- Confidentiality: Ethical hackers must treat any information discovered with confidentiality.
4. Methodology:
- Reconnaissance: Gathering information about the target system or network.
- Scanning: Identifying live hosts, open ports, and services running on servers.
