As some of the others pointed out, there's a lot to be considered when securing a website login form. Some other things to consider are:
  • If the login is wrong, don't let on whether it was the username or password that was wrong.
  • If you print out the username (e.g. you print 'there is no user Bob registered here') make sure you html encode the username first to prevent cross-site scripting attacks.
  • The choice of session id hashing algorithm is important. MD5, the default in many cases is not really suitable for applications which require a good level of security.
  • Make sure any database lookups you do carry out are protected against SQL injections.
And there's plenty more. You can get a bit of an introduction to website security at my site WebsiteSecurityBook.com. (it's all free). I'm gathering up information on all the different security issues to be considered when securing websites.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
