Is it worth using https if you are not doing financial transactions?

Hey just a quick question for any experts out there. I have a site that lets users interact through messages and to sign up you just make a username and password, verify your age, and optionally, add an email.

Can I tell if the iPhone has a passcode?

I'm developing an application that asks for a PIN when you start it. That's not great, but I can live with it. The problem is I'm being asked to ask for the PIN each time the phone wakes from sleep, too. Combined with the OS asking for its passcode, it's too much. Is there any legitimate way to detect if the phone has a passcode require...

How should I protect against hard link attacks?

I want to append data to a file in /tmp. If the file doesn't exist I want to create it I don't care if someone else owns the file. The data is not secret.

MVC Pages that require the user to be logged in

I'm working on a little MVC framework and I'm wondering what the "best way" is to structure things so secure pages/controllers always ensure the user is logged in (and thus automatically redirects to a login page--or elsewhere--if not). Obviously, there are a lot of ways to do it, but I'm wondering what solution(s) are the most common o...

One of our customers did a security audit of our site and flagged that as an issue. The auditor's statement was that if we also had a XSS vulnerability that an attacker could grab another user's a...
