Unit I: Introduction to Ethical Hacking

Evolution of hacking: transition from malicious attacks to ethical hacking for security.
Ethical hackers perform penetration testing using defined methodologies.
Fundamentals of computer networks: focus on TCP/IP, network devices, and security tools such as proxies and firewalls.
Cryptography basics: symmetric and asymmetric methods, hashing, and application issues with technologies like IPsec and SSL.

Unit II: Footprinting and Scanning

Footprinting: process of gathering information to identify potential vulnerabilities.
Threats from footprinting: includes revealing sensitive information through social networks and other sources.
Scanning: identifies live systems and open ports, differentiating between various scan types and OS fingerprinting.
Tools for vulnerability scanning; the significance of employing proxies for anonymity.

Unit III: Enumeration and System Hacking

Enumeration: the process of extracting detailed information from a system or network.
Techniques vary for different systems (e.g., Windows, SNMP, LDAP).
System hacking involves password cracking and security authentication methods, particularly on Microsoft platforms.
Malware classifications: differentiate between viruses, worms, and ransomware while acknowledging legal implications.

Sniffers: tools used to monitor network traffic; methods to employ them and countermeasures against sniffing attacks.
Social engineering: psychological tactics employed to deceive individuals into revealing confidential information.
Denial of Service (DoS): methods of subverting services, emphasizing the distinctiveness of DoS and Distributed Denial of Service (DDoS).

Unit V: Session Hijacking, Web Security, and SQL Injection

Session hijacking: understanding its mechanics and defensive strategies.
Web servers and applications: vulnerabilities in client-server relationships, methods to test web applications.
