user-accounts

I am trying to write a website that has user accounts. There isn't much sensitive information other than the password and email address. But I don't really understand what I'm doing; I'm kind of hacking it along as I go. Is there anything I should be keeping in mind with respect to security or any other important details? You should: encrypt sensitive data avoid: avoid sql injection Session hijacking Session fixation Recommended Reading: PHP Security Guide Sarfraz Ahmed brought up some good resources for reading. You could also use a PHP class for user authentication, there are plenty. I my

I could grep through /etc/passwd but that seems onerous. 'finger' isn't installed and I'd like to avoid that dependency. This is for a program so it would be nice if there was some command that let you just access user info. You don't specify a programming language, so I'll assume you want to use the shell; here's an answer for Posix shells . Two steps to this: get the appropriate record, then get the field you want from that record. First, getting the account record is done by querying the passwd table : $ user_name=foo $ user_record="$(getent passwd $user_name)" $ echo "$user_record" foo:x

So there are definitely many tutorials out there regarding how to integrate various individual social network authentication/registration into existing user accounts. But the scenario I can't seem to find out much information about is if a user signs into your account with different social network credentials. For example: Scenario #1 User registers on site using site's authentication. User then signs in/registers on site using Facebook Connect. User then signs in/registers on site using Twitter. How do I integrate all of these into one account? Obviously once a user is registered, they can

I have this command $remoteuserlist = Get-WmiObject Win32_UserAccount ` -filter "LocalAccount =True" –computername $PC -verbose that I am running to get a list of local accounts on a machine. I would also like to exclude the guest account from my list. so I tried something like this $remoteuserlist = Get-WmiObject Win32_UserAccount ` -filter {LocalAccount =True -and Name -ne "Guest" –computername $PC -verbose} but I get an invalid query error. Can someone explain my presumably blindingly obvious error? Thanks $remoteuserlist = Get-WmiObject Win32_UserAccount -filter {LocalAccount = "True" and

I have been trying for days to get a list of logged in users in a Meteor chat app. I tried many different things. I managed to add a login flag on the user profile object. Server side: Accounts.onCreateUser(function(options, user) { if(!options.profile){ options.profile = {} } options.profile.login = false; if (options.profile) user.profile = options.profile; return user; }); In the browser console I get this: Meteor.user().profile Object {login: false} So that seems to work. Now I want to list if users are logged in: Client side Deps.autorun(function(){ if(Meteor.userId()){ Meteor.user()

I had to delete over 90 users in my web api. I am using web api 2 individual account. But after deleting this users, they still can use my web-api, because access token are cached somewhere. How to prevent that? because tokens are stored on the client and not on the server, u can't manually invalid token. but i found three solutions: 1'st - Just wait until tokens expire (14 days, it was too long for me) 2'nd - changing the date on the server, when i add'ed 14 days to server date, All tokens expired (but on production server this was unacceptable) 3'rd - Changing machine key on server. 来源：

I created my own parental control app using C# to monitor my kids activity. It logs all the keyboard input and screens in the background silently, with the only gui of taskbar icon. So far, I just let it run in my admin account and everybody share the same account and it works fine. The problem is that as kids grow up, they found a way to kill it from the task manager. So, I need to use a more sophisticated way to protect my app. I thought I could solve this problem easily by creating a separate standard account for each kid and I can setup my app to run as an admin to monitor all their
