CYBERTOOLS:3- Host Discovery and Port Ranges (output to file)


This a guide to use them:-

nmap -A is the aggressive option that use os detection , service detection and scripts to determine any and all information on a target. (Not to be used on a target machine on which you have no authorization)

nmap -sn tells a which hosts are up and works similar to netdiscover

nmap -p helps us specify port 

nmap -F scans first 100 ports 

HOW TO OUTPUT A NMAP SCAN 

nmap <arguements and ip port etc> >> filename.txt

Results in a file as well as displayed on the terminal

nmap -oN filename.txt

CYBER-BASICS 3: SQL

Image
 Structured Query Language  SQL is used when a database is connected to a site allowing you the capabilities to store,retrieve and search for data. Different users will have different authorization over the access of data.   The most common thing done on sql databases is sql injection. SQL can be used in login pages for a website, the log in information for websites will sent to the server as a form of query and if the information the database will report back to the application. After this the the user permission will be granted by a cookie or an authentication token stored both in the browser and in the server.   The reason a site uses services for sql is that they need to store data somewhere and PIIs(Personally Identidiable Information) such as passwords, messages etc need to be saved.  Some common techniques of sql attack defenses are 1) input validation(compares input against malicious and non malicious preknown inputs) 2) parametrized queries(makes sure sql diffrentiates between

CYBERTOOLS:4-Using Decoys and Packet Fragmentation in nmap to bypass firewalls

 Using Decoys and Packet Fragmentation in nmap to Bypass Firewalls How to know if a device has firewall:- nmap tells us the port is filtered if the port hides behind a firewall or ids PACKET FRAGMENTATION  nmap -f is used to fragment packets. TCP header is split into parts so that the firewall has hard time reading content you can specify -f multiple times to split a packet again and again. -f once will give 8 byte packet -f -f will give 16 byte packet the more smaller the packet the harder it is to handle  to split packet into custom amount of bytes use nmap --mtu <value> this will split packet into your choice of bytes  while using --mtu the value must be a multiple of 8 USING DECOYS Using decoys work by making the target think that multiple ips are scanning a single target. This will make it harder to determine which ip are innocent and which ip are the culprit. This can be defeated by router path tracing , response dropping and other mechanisms, but is still an effective tec

SNORT Installation

Image
 1) Make sure that your kali has the following setting in the following way 2) open kali and type the following command in the terminal to check ip address and copy it or remember it  the command is "ifconfig" 3) type the following command to start snort installation  sudo apt-get install snort 4) type your ip range as required 5) go to snorts directory and create a backup of the snort.conf as we will edit it soon  to create backups use the following commands  "cp snort.conf snort.conf.back" 6) we create another backup for the snort file to edit  using the command "cp snort.conf test_snort.conf" 7) we edit with a file editor i am using nano and put your ip range  using the command  sudo nano test_snort.conf 8) test your snort changes using the following command  the command is "sudo snort -T -i eth0 -c /etc/snort/test_snort.conf" 9) now we define our new rules  10) then we test it again using the command in step 8 11) then we start using our snor
