Migration from Wordpress to CodeIgniter

Hello everyone,

1. Is CodeIgniter a really strong platform regarding security?

CodeIgniter Security Features:
Below are some of the best practices about Internet security and some coordinate Internet security features.
URI protection
CodeIgniter helps to reduce the possibility of malicious data that sends any tools to your URI strings.
XSS Filtering
CodeIgnitor cross site scripting filter comes with. These filters use tactics to try to steal your data or other cookies on malicious JavaScript or other types of malicious things.
The XSS filter should only be executed. Filtering input data can change data in unnecessary ways, except for special characters avoiding passwords and enhancing security.
SQL Injection
In a SQL injection attack, the insertion from the client will insert the SQL query or "injection". Successful SQL injection query can read data from database, change data. Unauthorized user activates crawl functions and destroys database with SQL queries.
CSRF security
The CSRF is referred to as a cross-site request forgery, which is an invader's way of repaying their victim's wrong appeal to the request.
CodeIgniter provides CSRF protection from the box, each GET HTTP request can be automatically triggered, but your specific forms must be submitted in a certain way.
Confirm input data
CodeIgnitor is a form validation library that supports your data, sorting and processing. If your application does not work in case, always check and erase all input data.
Tap all the data before inserting the database
Do not block information in your database. For more information, see the section discussing database queries.
Hide your files
Another good security procedure will only leave your index.php and assets. These are the only files you can access from the Internet. If your viewers are allowed to see anything else, you can access important data and enable scripts.

So, yes it is !
