CEH v10 Scanning Methodology


CEH v10 Scanning Methodology



After footprinting phase, you may have enough information about the target now is Scanning network phase requires some of this information to proceed further. Scanning is a set of procedure For identifying live hosts, port and services, discovering operating system and architecture of targeting system identifying vulnerabilities and threats in the network.



Scanning Methodology

 

check for live systems

  •        - ICMP Scanning
  •        - Angry IP
  •        - HPING3
  •        - Hping3 commands
  •        - Ping Sweeps
  •        - Firewalks tool
      
      
      

1) Check for live systems :



scanning for live system :- In this type of scanning, it is found out which hosts are up in a network by pinging them all.

ICMP scanning can be run parallel so that it can run fast.
It can also be helpful to tweek the ping timeout value with the -t option.




Ping



Ping scan involves sending ICMP ECHO request to a host. If the host is live, it will return an ICMP ECHO reply. This scan is useful for locating active  devices or determining if ICMP is passing through a firewall. CEH v10 Scanning Methodology


Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. ... Ping operates by sending Internet Control Message Protocol (ICMP) echo request packets to the target host and waiting for an ICMP echo reply.

ICMP



ICMP (Internet Control Message Protocol) is an error-reporting protocol network devices like routers use to generate error messages to the source IP address when network problems prevent delivery of IP packets.




2) Ping Sweep


A ping sweep (also known as an ICMP sweep) is a basic network scanning technique.


Ping sweep is used to determine the live hosts from a range of IP Addresses by sending ICMP ECHO request to multiple hosts. If a host is live, it will return an ICMP ECHO reply.


Attackers calculate subnet masks using Subnet Mask calculator to identify the number of hosts present in the subnet.


Attackers then use ping sweep to create an inventory of live systems in the subnet.


A ping sweep consists of ICMP ECHO requests sent to multiple hosts If a given address is live, it will return an ICMP ECHO reply.




3) Angry IP  ( Ping Sweep Tool ) 



Reproduction is strictly prohibited Angry IP.

An IP scanner for Windows Can scan IPs in any range It simply pings each IP address to check if it is alive Provides NETBIOS information such as:




  • Computer name
  • Workgroup name
  • MAC address



Angry IP Scanner pings each IP address to check if it's alive, then optionally resolves its hostname, determines the MAC address, scans ports, etc.

SolarWinds Engineer Toolset's Ping Sweep enables scanning a range of IP addresses to identify which IP addresses are in use and which ones are currently free. It also performs reverse DNS lookup.

4) HPING3



hping3 is a network tool able to send custom TCP/IP packets and to display target replies like ping program does with ICMP replies. hping3 handle fragmentation, arbitrary packets body and size and can be used in order to transfer files  encapsu‐ lated under supported protocols. Using hping3 you are able to perform at least the following stuff:


HPING is a command-line oriented TCP/IP packet assembler/analyzer.

It not only sends ICMP echo requests but also supports
TCP
UDP
ICMP and 
Raw-IP protocols
Has a Traceroute mode
Ability to send files between a covered channel.


Features



  • Firewall testing
  • Advanced port scanning
  • Network testing, using different protocols, TOS, fragmentation
  • Advanced Traceroute, under all the supported protocols
  • Remote OS fingerprinting
  • Remote uptime guessing
  • TCP/IP stacks auditing.



Hping3 command :- 


hping3 192.168.42.165 ( This command sends a TCP null-flags packet to port 0 of host 192.168.52.165


hping3 192.168.42.165 -p 80 ( This command sends the packet to port 80


hping3 -a 192.168.42.1 -S -p 81 192.168.42.25 ( Send spoofed SYN packets to the target via a trusted third party to port 81


hping3 www.debian.org -p 80 -A ( Send ACK to port of www.debian.org


hping3 www.yahoo.com -p 80 -A ( checks for IPID responses

5) Firewalk 

 

Firewalk Tool Firewalking is a tool that employs traceroute-like techniques to analyze IP packet responses to determine gateway ACL filters and map networks.

The tool employs the technique to determine the filter rules in place on a packet forwarding device Hop 0 PACKET FILTER Hop n Firewalking Host Internet Hop n+m (m>1) Destination Host



apt-get install firewalk -y
