Course Layout:

  • Week 1:   Introduction to ethical hacking. Fundamentals of computer networking. TCP/IP protocol stack.
  • Week 2:   IP addressing and routing. TCP and UDP. IP subnets.
  • Week 3:   Routing protocols. IP version 6.
  • Week-4:   Installation of attacker and victim system. Information gathering using advanced google search, archive.org, netcraft, whois, host, dig, dnsenum and NMAP tool.
  • Week-5:  Vulnerability scanning using NMAP and Nessus. Creating a secure hacking environment System Hacking: password cracking, privilege escalation, application execution. Malware and Virus. ARP spoofing and MAC attack.
  • Week 6:   Introduction to cryptography, private-key encryption, public-key encryption.
  • Week 7:   Cryptographic hash functions, digital signature and certificate, applications.
  • Week 8:   Steganography, biometric authentication, network-based attacks, DNS and Email security.
  • Week-9:   Packet sniffing using wireshark and burpsuite, password attack using burp suite. Social engineering attacks and Denial of service attacks.
  • Week 10: Elements of hardware security: side-channel attacks, physical inclinable functions, hardware trojans.
  • Week-11: Different types of attacks using Metasploit framework: password cracking, privilege escalation, remote code execution, etc.Attack on web servers: password attack, SQL injection, cross site scripting.
  • Week 12: Case studies: various attacks scenarios and their remedies.
