Hello dosto ,kya aap jante hai ki IP spoofing aur denial of service 2 bahut hi popular and most useful attack hai jinhe intruders  kisi perticular target ke kiye use kiye jate hai.Iske baare me Aage batane se pehle ye jaan lo isnme difference kya hai ,Ip spoofing kisi network ki routing table ko target karne ke liye kiya jata hai jabki DOS attack ka kaam hota hai kisi perticular targeted computer ke resources ko burn karna ,seedhi langauge me computer ko nuksan pahuchana.

Ip spoofing and dos attack ka people apne apne tarike se use karte hai,aur yadi aap iski depth tak jana chahte hai to aapko pehle computer network ka basic samjhna hoga and network ko analyze karne ki kosis karni chahiye aur janne ki kosis karna ki iske peeche jo technicality hai wo kya hai tabhi aap Ddos attack ka sahi use kar paoge.

To chaliye main aapko ek ek karke iske baare me batata hoon jisse aapka basic achha ho jayega.

What is IP spoofing?

jab koi computer aapke network ke outside ho aur usko lage ki wo kisi trusted network ke sath juda huya hai to ye action jo attacker dwara kia jata hai isi process ko ip spoofig kehte hai.Jab koi ek computer dusre computer se judta hai to wo ek dusre ka ip note karte hai aur ye insure karte hai ki ye trusted hai ya nhi.To isi baat ka fayda uthakar apke network ki had me ek ip address use karte hai or In other hand attacker koi authorized extrenal ip address ka use karte hai jo ki network ko trusted lage.Isko main apne agle post me aur achhe se samjhunga kyonki isme bahut kuchh aata hai jo main is post me clear karunga to post bahut lenghty ho jayega.
To chaliye is post me dekhte hai kya different ways hai ip ko spoof karne ke.

Different ways of IP spoofing?

1. Attacker iske liye sabse achha ye tarika apnate hai ki wo simply client and server application ke beech me kuchh set of commands ya fir injection of data ko pass karate hai aur isse wo ip ko spoof kar lete hai,is method ko janne ke liye pehle ip ko achhe semajhna hota hai aur network ki achhi knolwdedge gain karni hoti hai. 

3. Jaisa ki maine upar bataya tha ki attacker kisi network ki routing table ko change karke ip spoof kat lete hai ,actualy routing table change karne se attacker bidirectional communication enable kar leta hai.And ek baar routing table change ho gayi to attacker ka kaam bahut simple ho jata hai aur wo badi aasani se kisi bhi network se data recieve karne lagta hai.

Denial of Service (DOS) attacks:

Aap ek tarike se ye soch sakte hai ki DoS attak ek modified version hai Ip spoofing ka.But Ip spoofing ki tarah ddos attack me attacker ko is baat ki chinta nhi hoti hai ki perticular network use responce de ya kuchh bhi data recieve karne de.Balki Ddos attack me attacker simply kisi perticular network ko itni reauest de deta hai ki wo unhi request ko pura karne me busy ho jata hai tab tak attacker apna kaam kar deta hai. Agar hum is attack ki  technicality par baat kare to jo targetd computer ka host hota hai wo ek TCP SYN recieve karta hai and iske badle me ek SYN-ACK ko send kar deta hai attacker ko.

Jab bo SYN-ACK ko attacker ko send karta deta hai iske baad uske mesage ke reply ka wait karta hai ek TCP ko pura karne ke liye ,jab ye process ho jati hai ise handshake process kahte hai kyonki is process me computer ko lagta hai wo kisi trusted ip se contact kar raha hai.Dos attack karne ke liye hacker ddos ka use karte hai ,Ddos attack ek bahut hi popular tool hai jo hacker online works ko nukasan pahuchane me kaam me lete hai.Iske baare me aage me main aapko bataunga ye kaise work karta hai lekin iske liye mere agle post ka wait kariye. Usme aap janenge ki kaise hacker ka ek pura group jiska naam hai  hacktivists aur dusre bhi online group ddos ko perfom karte hai.
To aaj ke post me sirf itna hi tha ,isme maine sirf basic ko cover karne ki kosis ki hai agar mujhe is post ka achha responce mila to main Aage aapko aisi hi bahut si technial baate batunga jo aapki knowledge point of view se bahut hi faydemand hogi.Kyonki aaj ki is duniya me bahut se technical kaam humare aas paas hote rehte hai lekin actual me hume uski technicality pata nhi hoti to aaj se main yahi sab aapko bataunga .

Agar aapko ye post achha laga ho to please  isko share jarur kariye taaki is post ko jayda se jyada log padh sake aur mujhe bhi aage aapo isi type  ki knowledge provide karane me maja aaye.
