  1. In Topic: Detect if users leave the domain

    Posted 1 Apr 2013

    I thought by killing the session I could stop someone from getting sensitive data like Social Security Numbers or Credit Card Numbers, how secure are sessions? Am I worrying too much about nothing?

    What are you asking is quite unusual, at least for me. The only idea I have would be to pass a value from page to page via POST method every time the user clicks a link, asking for a new page. Then you can check if the value was set, if not it means the request wasn't sent from one of your pages.

    [snip]

    However, there's a major problem in this design and I'm talking about the user ability to change the url via address bar. There's no problem if they want to go on a different website, but if they access another one of your pages a new session is created, even though the user never left the website.


    I see your point, but how much security should you have for an eCommerce website? Also If the browser is using tabs like Firefox, closing the tab does not kill the session.

    If the user closes the window or goes to another website a new session should be started.

    Suppose you somehow got this working. What would you want to do if the user left your window open but used another browser? Would you kill the session then too if you could? Why would you, and if you wouldn't then why do you want to if they browse a different page on the same browser?

    I am trying to write a basic eCommerce web site where the same user can add items to a shopping cart with a click and php will know that it is the same user for the same session. (For this web site the user has no log in button, stupid I know but these are my requirements) If the user closes the window or goes to another website a new session should be started.

    Here is my new working code, thanks for all the help

    ;filename: arrayTest.asm

.DATA

outputLabel          BYTE    "The number inside the array is",0
messageOut           BYTE    "End Program",0
stringArray          BYTE    "Good Bye World",0
stringOUT            BYTE    100 DUP (?)
numberArray          DWORD   100 DUP (?)   ;Declare an uninitialized array 100 DWORDs long
numberValue          DWORD   ?
numberOfElements     DWORD   ?

.CODE
_MainProc      PROC

    output    outputLabel,          stringOUT            ;display message box with label and the converted string
    inc       ecx                                        ;ecx = ecx + 1
    dec       numberOfElements                           ;numberOfElements = numberOfElements - 1
  cmp         numberOfElements,     0                    ;compare numberOfElements with 0
  jne          bobby                                     ;if numberOfElements does not = 0 then jump to label bobby
  
  output      messageOut,           stringArray          ;display message box "Good Bye World"

  mov          eax,                  0                   ;exit with return code 0
  ret
_MainProc      ENDP
END


    Once again thank you, you have been a big help!

    Posted 26 Mar 2013

    My book does not discuss xor for another two chapters, please tell me what this code this
    xor     esi, esi


    I know it is the inverse or the logical "or" instruction and will produce a "1" for every non matching pair of "1's" and "0's" but what is the net effect of the above instruction why is it used?
    If I wanted to zero out esi I can use

    mov  esi,  0
