Security for Wordpress and Codeigniter

I want to integrate wordpress and codeigniter and I am confuse about security.My admin panel will be in codeigniter and frontend in wordpress.what type of security is there.

It depends on code you write.there is some points that should be notice.

  1. CI store session in cookie. so you can encrypt session in config.php file or you can use database for storing session.
  2. I think proper form validation should be there if you are building your application in CI or in any other framwork.
  3. you can generate or enable csrf_protection so that when a form is being submit token should be match.
  4. there is a lots of infomation you can find Click Here
    hope it help you in some way.
