CSRF And CSRF Token

What is a CSRF token? A CSRF Token is a secret, unique and unpredictable value a server-side application generates in order to protect CSRF vulnerable resources. The tokens are generated and submitted by the server-side application in a subsequent HTTP request made by the client. After the request is made, the server side application compares the two tokens found in the user session and in the request. If the token is missing or does not match the value within the user session, the request is rejected, the user session terminated and the event logged as a potential CSRF attack. How should CSRF tokens be generated? Just like session tokens in general, CSRF tokens should contain significant entropy and be strongly unpredictable. You can achieve this by using a cryptographic strength pseudo-random number generator (PRNG), seeded with the timestamp when it was created and a static secret. For further security, you can generate individual tokens by chaining their outputs with user-specific entropy and take a strong hash of the whole structure. This presents an additional obstacle to a malicious user who attempts to analyze the tokens based on a sample that is issued to him. In short, here are the principles you should follow when generating and verifying your token: Use a well-established random number generator with enough entropy Make sure tokens can’t be reused. Expire them after a short amount of time Verify the received token is the same as the set token in a safe way, for example, compare hashes Do not send CSRF tokens in HTTP GET requests. This will make sure they are not directly available in the URL and they don’t leak in the Referer header with other referrer information #hack #hacks #hacker #hackney #hacking #hacked #hackers #hackathon #hackneywick #Hackerofkrypton #hackintosh #hackfleisch #hacksquat #hackett #Hackensack #hacklife #hackettstown #Hackerpschorr #hackettstownnj #hackerman #hacktivist #hackerbr #hackeschermarkt #hacksawjimduggan #hackaton #hackrio #hackneyroad #hacksawridge #hackerspace #hackerbolt #hacks #hacker #hackney #hacking #hacked #hackers #hackathon #hackneywick #Hackerofkrypton #hackintosh #hackfleisch #hacksquat #hackett #Hackensack #hacklife #hackettstown #Hackerpschorr #hackettstownnj #hackerman #hacktivist #hackerbr #hackeschermarkt #hacksawjimduggan #hackaton #hackrio #hackneyroad #hacksawridge #hackerspace #hackerbolt #hacktivism #cybersecurity #cybersecurityawareness #cybersecuritythreats #CyberSecurityAwarenessMonth #cybersecurityengineer #cybersecuritytraining #cybersecurityconsultant #cybersecurityprogram #cybersecurityuae #cybersecuritysummit2017 #cybersecuritysummit #CyberSecurityStartup #cybersecuritymonth #cybersecuritymarathon #cybersecurityexperts #cybersecurityexpert #cybersecuritydubai #cybersecurityconvention #cybersecurityawareness01111000 #cybersecurityanalyst #CybersecurityZEN #cybersecurityawareness #cybersecuritythreats #CyberSecurityAwarenessMonth #cybersecurityengineer #cybersecuritytraining #cybersecurityconsultant #cybersecurityprogram #cybersecurityuae #cybersecuritysummit2017 #cybersecuritysummit #CyberSecurityStartup #cybersecuritymonth #cybersecuritymarathon #cybersecurityexperts #cybersecurityexpert #cybersecuritydubai #cybersecurityconvention #cybersecurityawareness01111000 #cybersecurityanalyst #CybersecurityZEN #shorts #shortstory #shortstories #shortshorts #shortsleeve #shortskirt #shortstop #shortsale #ShortStyles #shortsaia #shortsph #shortsales #shortsnouts #shortstyle #shortstack #shortsjeans #shortstuff #shortstay #shortsleeves #shortsleevesshirt #shortset #shortsexyhair #shortsbrewing #shortshirt #shortstocks #shortsleeveshirt #shortsqueeze #shortsighted #shortsewin #shortshift #virus #virushka #virusintl #virusvideo #VirusRemoval #viruses #virusprotection #virusjack #virusremovals #VirusImperial #virusdetectadoapagalo #viruscleanup #virushkalove #virushkaslays #virusvodka #Virus01170 #virussound #virusshawl #VIRUSPARIS #VirusToys #virusti #virushkafanpage #virushkaforever #virusremove #VirusRap #virusinfection #virusinformaticos #virusinsta #VirusPerformanceUK #virusperformance #virushka #virusintl #virusvideo #VirusRemoval #viruses #virusprotection #virusjack #virusremovals #VirusImperial #virusdetectadoapagalo #viruscleanup #virushkalove #virushkaslays #virusvodka #Virus01170 #virussound #virusshawl #VIRUSPARIS #VirusToys #virusti #virushkafanpage #virushkaforever #virusremove #VirusRap #virusinfection #virusinformaticos #virusinsta #VirusPerformanceUK #virusperformance #virusMydreamsclub
