1 : Ethical Hacking
2 : Ethical Hacking - ? Why – Ethical Hacking ? Ethical Hacking - Process Ethical Hacking – Commandments Reporting
3 : Ethical Hacking Conforming to accepted professional standards of conduct What is Ethical Hacking Process of breaking into systems for: Personal or Commercial Gains Malicious Intent – Causing sever damage to Information & Assets Also Called – Attack & Penetration Testing, White-hat hacking, Red teaming White-hat - Good Guys Black-hat – Bad guys
4 : What is Ethical Hacking It is Legal Permission is obtained from the target Part of an overall security program Identify vulnerabilities visible from Internet at particular point of time Ethical hackers possesses same skills, mindset and tools of a hacker but the attacks are done in a non-destructive manner
5 : Why – Ethical Hacking Source: CERT-India January - 2005 Defacement Statistics for Indian Websites
6 : Why – Ethical Hacking Source: CERT/CC Total Number of Incidents Incidents
7 : Why – Ethical Hacking Source: US - CERT
8 : Why – Ethical Hacking Protection from possible External Attacks
9 : Ethical Hacking - Process Preparation Footprinting Enumeration & Fingerprinting Identification of Vulnerabilities Attack – Exploit the Vulnerabilities
10 : Preparation Identification of Targets – 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
11 : Footprinting Collecting as much information about the target DNS Servers IP Ranges Administrative Contacts Problems revealed by administrators Information Sources Search engines Forums Databases – whois, ripe, arin, apnic Tools – PING, whois, Traceroute, DIG, nslookup, sam spade
12 : 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, FScan, Hping, Firewalk, netcat, tcpdump, ssh, telnet, SNMP Scanner
13 : Identification of Vulnerabilities Vulnerabilities Insecure Configuration Weak passwords Unpatched vulnerabilities in services, Operating systems, applications Possible Vulnerabilities in Services, Operating Systems Insecure programming Weak Access Control
14 : 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
15 : Identification of Vulnerabilities Tools Vulnerability Scanners - Nessus, ISS, SARA, SAINT Listening to Traffic – Ethercap, tcpdump Password Crackers – John the ripper, LC4, Pwdump Intercepting Web Traffic – Achilles, Whisker, Legion Websites Common Vulnerabilities & Exposures – Bugtraq – Other Vendor Websites
16 : Attack – Exploit the 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
17 : Attack – Exploit the vulnerabilities Network Infrastructure Attacks Connecting to the network through modem Weaknesses in TCP / IP, NetBIOS Flooding the network to cause DOS Operating System Attacks Attacking Authentication Systems Exploiting Protocol Implementations Exploiting Insecure configuration Breaking File-System Security
18 : Attack – Exploit the vulnerabilities Application Specific Attacks Exploiting implementations of HTTP, SMTP protocols Gaining access to application Databases SQL Injection Spamming
19 : Attack – Exploit the vulnerabilities Exploits Free exploits from Hacker Websites Customised free exploits Internally Developed Tools – Nessus, Metasploit Framework,
20 : Reporting Methodology Exploited Conditions & Vulnerabilities that could not be exploited Proof for Exploits - Trophies Practical Security solutions
21 : Ethical Hacking - Commandments Working Ethically Trustworthiness Misuse for personal gain Respecting Privacy Not Crashing the Systems
