  WHY SHOULD WEKNOW ABOUT CEH? • In this Tech-savvy world of 21st Century every one is engaged with internet, through whatsapp , twitter, facebook , net-banking & lots of other platforms are there. • And some criminal minded persons commit crimes here, which is included under cyber-crime. • We should be aware about crimes happening around in the cyber-space, so we can protect ourselves.
• 3.
  WHAT A CEHDO? •  A CEH is hired to locate and repair application and system security vulnerabilities to preempt exploitations by black hat hackers and others with potentially illegal intentions.  •Ethical hackers employ the same tools and techniques as the intruders.

  EXAMPLES OF CYBERCRIME

  STEPS FOR PENTESTING 1. Preparation 2. Footprinting 3. Enumeration & Fingerprinting 4. Identification of Vulnerabilities 5. Attack – Exploit the Vulnerabilities 6. Cover tracks
• 6.
  PREPARATION • Identification ofTargets – company websites, mail servers, extranets, etc. • Signing of Contract • Agreement on protection against any legal issues • Contracts to clearly specifies the limits and dangers of the test • Specifics on Denial of Service Tests, Social Engineering, etc. • Time window for Attacks • Total time for the testing • Prior Knowledge of the systems • Key people who are made aware of the testing
• 7.
  FOOTPRINTING Collecting as muchinformation about the target •DNS Servers •IP Ranges •Administrative Contacts •Problems revealed by administrators Information Sources •Search engines •Forums •Tools – PING, whois, Traceroute, nslookup,
• 8.
  ENUMERATION & FINGERPRINTING •Specific targets determined • Identification of Services / open ports • Operating System Enumeration • Methods • Banner grabbing • Responses to various protocol (ICMP &TCP) commands • Port / Service Scans – TCP Connect, TCP SYN, TCP FIN, etc. • Tools • Nmap, tcpdump, ssh, telnet
• 9.
  IDENTIFICATION OF VULNERABILITIES Vulnerabilities •Insecure Configuration •Weakpasswords •Unpatched vulnerabilities in services, Operating systems, applications •Possible Vulnerabilities in Services, Operating Systems •Insecure programming •Weak Access Control
• 10.
  IDENTIFICATION OF VULNERABILITIES Methods •Unpatched /Possible Vulnerabilities – Tools, Vulnerability information Websites •Weak Passwords – Default Passwords, Brute force, Social Engineering, Listening to Traffic •Insecure Programming – SQL Injection, Listening to Traffic •Weak Access Control – Using the Application Logic, SQL Injection
• 11.
  ATTACK – EXPLOITTHE VULNERABILITIES • Obtain as much information (trophies) from the Target Asset • Gaining Normal Access • Escalation of privileges • Obtaining access to other connected systems • Last Ditch Effort – Denial of Service
• 12.
  ATTACK – EXPLOITTHE VULNERABILITIES • Network Infrastructure Attacks • Connecting to the network through modem • Weaknesses in TCP / IP, NetBIOS • Flooding the network to cause DOS • Operating System Attacks • Application Specific Attacks • Exploiting implementations of HTTP, SMTP protocols
• 13.
  ATTACK – EXPLOITTHE VULNERABILITIES • Gaining access to application Databases • SQL Injection • Spamming Exploits • Free exploits from Hacker Websites • Customised free exploits • Internally Developed • Tools – Nessus, Metasploit Framework
• 14.
  REPORTING Methodology •Exploited Conditions &Vulnerabilities that could not be exploited •Proof for Exploits - Trophies •Practical Security solutions
