Top 100+ Application Security Interview Questions And Answers
Question 1. Describe The Last Program Or Script That You Wrote. What Problem Did It Solve?
Answer :
All we need to see here is if the coloration drains from the man’s face. If he panics then we not only recognise he’s no longer a programmer (no longer necessarily horrific), however that he’s frightened of programming (awful). I realize it’s debatable, however I think that any excessive-stage protection man desires some programming abilties. They don’t want to be a God at it, but they need to recognize the standards and at the least be able to litter through some scripting while required.

Question four. What Is Cross-web page Request Forgery?
Answer :
Not knowing this is greater forgivable than not understanding what XSS is, but handiest for junior positions. Desired solution: whilst an attacker receives a victim’s browser to make requests, preferably with their credentials covered, with out their understanding. A solid instance of this is whilst an IMG tag factors to a URL associated with an action.
Example: http://www.Wisdomjobs.Com/logout/. A victim simply loading that web page may want to doubtlessly get logged out from foo.Com, and their browser might have made the motion, now not them (due to the fact browsers load all IMG tags automatically).

Nonces required by the server for every page or every request is an frequent, albeit not foolproof, technique.

Question 6. If You Were A Site Administrator Looking For Incoming Csrf Attacks, What Would You Look For?
Answer :
This is a a laugh one, because it calls for them to set some ground guidelines. Desired answers are such things as, “Did we already implement nonces?”, or, “That depends on whether we already have controls in region…” Undesired solutions are such things as checking referrer headers, or wild panic.
