Find Vulnerabilities Using Nmap

For finding vulnerabilities using nmap ..nmap scripts are used

1. nmap --script  vuln <target ip address>

 if  not getting apprpriate result use -d (for debugging)
        nmap --script vuln <target ip address> -d                         

2. If any website using firewall to block your request then you  can use other methods like (tcp scan,syn scan,ack scan,xmas scan) 
for bypassing firewalls and get appropriate results 

all scan  types are detailed in next post

  SYN SCAN  --  nmap -sS  <target ip address> 
TCP SCAN     --  nmap -sT <target ip address>
ACK SCAN    --  nmap -sA <target ip address> 


sometimes it block your ping request  for overcome this problem

use  no ping scan

                   nmap -Pn <target ip address>                                         

it will  show only ports (like open ,filtered,unfiltered)

now combine all  in one command

       nmap -sS -Pn --script vuln <target ip address> -d
