Basic security question

Hello,
I would like to know how we could secure the post variables in java. I could check for only valid input characters in the data but any suggestions would be helpful. Any other general security suggestions would be great. We primarily use jsp, servlets, java beans and mysql database. Thanks,

Thanks for your reply. For a start, I want to weed out any malicious characters that user enters through form input. In other words, We do upload files and store them on our linux system. We store general and payment information about the user in mysql database. First I would like to check for only acceptable characters and filter out the characters that would cause security hole in the system. Later I will focus on other aspects of security. I don't know which one to include in the set of acceptable characters. Any help will be appreciated.

  • Ipad apple ID account is deactivated and don't know the password or security questions

    I have had an ipad for 12 months, my husband created an icloud account on it ([email protected]) but since then we have never used the ipad to log into apple website, itunes etc.  Recently I purchased a MAC and iphone5 and after downloading the latest itunes to then sync all 3 together the ipad then asked for apple ID and password even though it had never asked for this before.  The trouble is the ipad apple ID is an icloud one, ie. an email account that belongs to Apple, so we cannot reset the password via email as we don't have access to the email, and one of the security questions answers comes up wrong all the time.  Because we have tried several times to remember the password the apple ID is now deactivated and the only way to re-activate it is via email verification (impossible) or security questions (impossible).  We tried connecting ipad to computer and restoring factory settings, but the ipad continues to ask for apple ID and password...help... customer service Apple in Spain has more or less told us if we can't remember the security questions or password and have no recovery email (which we don't) then basically the device is useless!!!! Urm, that ipad cost a lot of money to just "throw it away".  Any advice you can give me?

  • How do i deal with 'security certificate' issues on my iPad2? I'm unable to answer the security questions that pop up when Im trying to download an app because the pop up does not load properly...

    Basically my Ipad2 stopped allowing me to go to sites such as Tumblr a little while ago. It wouldn't display the page properly because of 'security certificate' issues. This in itself would not have been such a problem, but when I went to the App store to try and download the Tumblr App, a pop up appeared asking me to answer some security questions before I could successfully install the App. However, the pop up would not display correctly because of 'security certificate' issues and as a result I can't download any apps from the App Store. Can anyone help with this??

    Well, I maged to delete some stuff, download the update...
    My Mac mail is still not ok. Still only displays today, yesterday and everything is the 16th of the month previous to this?
    All a bit strange to say the least any suggestons on how to resolve this.

  • Apple is asking me to answer my security questions but I can't remember the answers. Also I would reset them but my rescue email is no longer in use and I cannot even remember what it was. Is there any way to fix this mess?

    So basically I need to confirm my identity but I  can't because I can't remember the answers to my security questions. I scheduled a meeting with Apple, to see if they can fix it. Nod I would just reset them from my rescue email, but I don't know what that email is and it's also no longer in use.
    Do you know of any way to fix this?

    You won't be able to change your rescue email address until you can answer your questions, you will need to contact iTunes Support / Apple in your country to get the questions reset.
    Contacting Apple about account security : http://support.apple.com/kb/HT5699
    When they've been reset you can then use the steps half-way down this page to update your rescue email address for potential future use : http://support.apple.com/kb/HT5312

  • How to call German Support from Asia to reset security question?

    Dear Apple Support,
    my dealer for my very first MAC computer  tried to install software and update OS to prepare notebook for "reday to use"status.
    It turned out that Apple has no service access to allow dealer to install and register software on customer behalf.
    So I needed to give him full access to my account.
    Since I'm new in this Apple things I was scared because with other OS I never ever had that requierement.
    But I already confirmed my MAC order so I could not cancle and step away from Apple.
    So I tried to process this request as save as possible. I removed all credit from account and gave a temporary password.
    I also tried to set security question to temporary values for my dealers access.
    But here something went wrong. So I ended up with obiviously unknow security question answers what blocks the access.
    The instructions on the screen and some screenshots in the change settings iinstruction show different (outdated) forms.
    Also the alternative approach with alternative email was not working.
    Why is it not possibel to forward user request for this reset request automatically to relevant support?
    I found also that the German support can't be called from abroad.
    Why is this not mentioned in list of international phone numbers?
    For some areas there is such a note but not for the German number!
    Finally I raised a case request to call back under my number, but Apple does not allow to change the country code.
    Because that way I had no chance,  I ask my dealer to assist and he called Apple support in Germany, but as they found out that he was acting on my behalf they kicked him out too times without further help.
    That was the moment I really regret that I spend now so much money for buying an Apple thing.
    I immediately cancle the Apple Care policy. Why should I pay for somthing if not even basic support is reliable.
    Apples does really good marketing, but in reality on second view when in real touch with Apple service it looks very poor.
    From user interface over usability of support process and dealer service all is so weak.
    Since Apple support kicked out the dealer,  I called in next attempt  a German person to relay my telephone request while being on Skype session.
    But what we there experienced was far more unfriendly.
    We picked up the call after 2-3 ring  and a computer voice wellcomed us and told us that Apple was not able to reach us.
    Furthermore they announced to call agian 10minutes later (10:21am MET +10min) we waited in Skype session over half an hour but no call back.
    I tried than to request again a call with clear indication that they pleas have to use my abroad number.
    But this results  in an email answer from Apple support that they can't reach me although the number they confirmed to are correct!
    My umber is also given in my data records in Apple-ID. So why is Apple support not able to escalate to second support level if something goes obviously goes wrong?
    May be too much automated system administration?
    After 1,5 days and many many emails, calls and endless frustration on my site and on authorized dealer side I need to escalate my simple request now over all channels I can find within the Apple universum.
    ontact details are all known to you and many request emails in your inbox refer to this case. My dealer contacts I already forwarded to Apple support email.
    Hey guys, I need just to get my security questions reseted! Can anybody assist please?
    Please inform we when done or call me under my:
    1. day number
    2. evening number
    3. Mobile number.
    4. Apple-ID email
    5. ooptional email
    6. or contact my relay in Germany under the number I send to you.
    PPLLLEEAASSEEEEE!

    Thanks roaminggnome for reminding me on this reference,
    that was one of the confusing webpages I found for this problem while using a simple search :-)
    But in my case the screen looked different and the procdure even more different than described in this easy to search posting.
    But don't worry Appel support also approached it in same way.
    The solution for this problem was much different.
    The scaring story with all this is that I had to give full account access and security question answers to a third party person helping as a relay to comunicate to Apple support.
    A simple search in free forums showed me that I'm not the only one having trouble with this Apple security strategy.
    Many thanks again!

  • How can I easily change my apple security questions

    About July of last year, I decided to purchase a $15.00 iTunes card. Since then, I've yet to be able to use it because I've yet to be able to find a way to change my security questions. I would be fine and happy if it weren't for the fact that, no natter what I do when I try to figure out how to change the questions, I get redirected to other pages that have no useful information or links that I can click to actually change my security questions. Mind you, I've been battling with this for nearly a year, and I've been tempted many times to just create a new iTunes account, but I feel that losing my money would be absolutely useless. I also feel that Apple Co. should be obligated to easily help their costumers in matters that aren't that uncommon, but that's a different story for a different time. Anyways, I've basically tried everything.
    So, in turn, does anyone have any way in the world that I can easily change my security questions without having to be redirected to so many different pages that my browser can't support/show them all? All kinds of help are greatly appreciated.

    I see what you mean. I don't think it's so much as the fact that it's "redirecting" me to all of these different pages, but more so the fact that it tells me to click these links, which normally turns out to be a link that I've more than likely clicked prior, and it takes me to a page that Ive already been on. The cycle restarts itself and I eventually get frustrated.

  • Hey guys can someone please tell me how to reset my security questions even after they have expired?

    Basically i was going to purchase something on my iPhone 4 and all of a sudden this security question thing came up, so i tried it once but it wouldn't work. Then i clicked the forgotten security questions and tried to answer it and reset the questions, there was no option to reset so i tried and tried to answer and eventually it said you have tried the maximum amount of times and now i don't know what to do please help me! i will be very grateful thank you.

    You need to ask Apple to reset your security questions. To do this, click here and pick a method; if that page doesn't list one for your country or you're unable to call, fill out and submit this form.

  • Is there another way into an iTunes account? Besides email verification and security questions? I'm not trying to hack I have rather extrodinary circumstances!

    Alright so I had an iTunes account that as you'd expect was linked to my email. Long story short my email got hacked and hotmail shut it down because my email address which I could no longer get into was sending spam to all my contacts. Anyway I used to keep a lot of the same passwords for different things and I realised that I had the same password for my email as I did for my hotmail so I decided to change both the password and the email of my iTunes account but then I encountered some difficulties. I had to either answer the security questions or verify my email. I'd long since forgotten what I'd put for the answers of the security questions so now I was stuck. So I called apple and the guy helped me 'sort it out'.
    I got my new account with its new email and new password and new email. But here's the thing now I can't get any of my old purchases. I've basically lost everything! So I need to get back into the old account and I've managed to get my broken old email restored so it should work now. But it doesn't the verification email doesn't come through! I need to get back on my old account. Someone please help!

    You can't get any of your purchases because you created a new Apple ID, you didn't change the email on your old one. App and other content is forever tied to the Apple ID used to purchase it. There is no way to transfer them and no way to merge Apple IDs.
    You need to call Apple back, explain the situation and tell them you need to change the email on your old Apple ID - NOT create a new one.

  • Basic iPhoto questions:

    I have some Basic iPhoto questions before I start using the program:
    - does iPhoto apply any compression or change images in any way when they
    are imported?
    - after images are imported, can the original source folder of images be deleted off of the mac?
    - can Quicktime files exported from iPhoto be viewed on a Windows computer?
    - can iPhoto handle large resolution images that might be as large as 8-15mb each? does it display them quick? are there any known file size issues?
    Thanks!!!!

    kat.
    Is there a way to use iPhoto on a network so other users can read and possibly write to an iPhoto library on a networked mac?
    iPhoto is a consumer level photo organiser, not a server. It's possible to share photos but libraries are very difficult and fraught with the danger of database corruption. Some have reported success.
    Is it possible to password protect or secure certain images in the library so they can not be seen by anyone?
    No. The best I can suggest there is to create a second library and store it in a secure area like a protected dmg. But remember, you can only have one library open at a time.
    After photos are deleted from iPhoto, are there any remaining traces or cached files anywhere other than the trash
    If you delete photos from iPhoto and empty the iPhoto trash then the pics are removed from the Finder as well. They remain as findable as any other deleted file from that point, which is, very, if the searcher in knowledgeable.

  • Why have my security questions changed?

    I received an email from apple today saying my security questions were updated. I did not do this. I immediately changed my password for my apple ID as a result. However, I cannot change my apple security questions and answers. I truly don't remember ever posting security questions and answers. How do I get help?

    May 2, 2012 6:25 PM (in response to chuckbee)
    Well, I got the same wonderful letter and called Apple nontech support because my computer is  4 years old so I'd have to pay Apple to tell them they messed up!
    Fortunately on the 2nd call I got a Senior Adviser (first level folks know only basics so I usually ask for a manager or supervisor).  In fact, I was told by 1st guy there were no managers, but then later he went to get someone and the phone went dead. Thankfully person 2 'Sterling' told me he would ask a Senior Adviser (so now I have another word to use for person above).  I asked given this issues importance to talk directly to the Senior Adviser and was allowed.
    Sterling (yes the adviser's name was the same as the tel answerer) said that Apple has been updating security questions, and from what he could tell, since I could log in that it was likely a glitch in their reworking security questions that caused this trouble.  He got me into my account by asking other questions which hadn't changed (last 4 of credit card, address), and I got in with my old password.
    So it could be a case of Apple messing up their own information.  They are setting some security questions as standard and you have to choose to make your own if you want.  They guessed my answers wrong by this theory.  I am still not 100% as sure as Sterling is that it was an inside job, and will be careful to watch my American Express Card since it's tied to my account as my boys wanted small items at iTunes.  May small not turn to big :-)   So you may have to call Apple to get things reset. Hope this helps.

  • I am trying to change my security questions, and it won't send the email to my email.

    It says it sent it to the email i am using, and it sent out the password change, but im not recieving the security question email. HELP

    I am having the same issue, it just won't send the e-mail. The options that apple provides you are:
    Alternatives for Help Resetting Security Questions and Rescue Mail
         1. Apple ID- All about Apple ID security questions.
         2. Rescue email address and how to reset Apple ID security questions
         3. Apple ID- Contacting Apple for help with Apple ID account security.
         4. Fill out and submit this form. Select the topic, Account Security.
         5.  Call Apple Customer Service: Contacting Apple for support in your
              country and ask to speak to Account Security.
    How to Manage your Apple ID: Manage My Apple ID
    Basically it tells you to go through the link to manage your ID and click on the link to send you the email (which we all did and clearly it's not workin)
    Then you can submit a form (which I did and was contacted but all they can manage to say is to call customer service as they are "not able to help" through e-mail. So the reply was to follow option 5, however I specified in the e-mail that I cannot call since I live in Costa Rica and cannot make international calls... THEY HAVE ME IN A LOOP I REALLY NEED TO GET OUT OF!!!!! If any one of you gets this issue fixed without calling, please let me know!
