SiteGround Security is the all-in-one security solution for your WordPress website.

== Description ==

With the carefully selected and easy to configure functions the [SiteGround Security](https://www.siteground.com/wordpress-plugins/siteground-security) plugin provides everything you need to secure your website and prevent a number of threats such as brute-force attacks, compromised login, data leaks, and more.

== Login Settings ==

Here you can use the tools we've developed to protect your login page from unauthorized visitors, bots, and other malicious behavior.

= Custom Login URL =
Change the default login url to prevent attacks and have an easily memorisable login URL. You can also change the default sign-up url if you have that option enabled for your website.

**Important!**
You can revert to the default login type by using the following snippet.

`
add_action( 'init', 'remove_custom_login_url' );
function remove_custom_login_url() {
	update_option( 'sg_security_login_type', 'default' );
}
`

= Login Access =
Login Access allows you to limit the access of the login page to a specific IP’s or a range of IP’s to prevent malicious login attempts or brute-force attacks.

**Important!**
If you lock yourself out of your admin panel, you can add the following option to your theme’s function.php, reload the site and then remove it once you have gained access. Keep in mind that this will also remove all IP's that are allowed to access the login page and a re-configuration will be needed:

`
add_action( 'init', 'remove_login_access_data' );
function remove_login_access_data() {
	update_option( 'sg_login_access', array() );
}
`

= Two-factor Authentication =
Two-factor Authentication for Admin User will force all admins to provide a token, generated from the Google Authentication application when logging in. 

**Important!**
You can force other roles to use the Two-Factor authentication as well. Once enabled, you can add your filter as the following.

`
add_filter( 'sg_security_2fa_roles', 'add_user_roles_to_2fa' );
function add_user_roles_to_2fa( $roles ) {
    $roles[] = 'your_role';
    return $roles;
}
`

You can change the location of 2FA encryption key file using SGS_ENCRYPTION_KEY_FILE_PATH constant defined in wp-config.php file. Make sure to use full path to the file. Example:

`
// Custom path to SG Security Encryption key file.
define ( 'SGS_ENCRYPTION_KEY_FILE_PATH', '/home/fullpathtofile/sgs_encrypt_key.php');
`

= Disable Common Usernames =
Using common usernames like 'admin' is a security threat that often results in unauthorised access. By enabling this option we will disable the creation of common usernames and if you already have one ore more users with a weak username, we'll ask you to provide new one(s).

= Limit Login Attempts =
With Limit Login Attempts you can specify the number of times users can try to log in with incorrect credentials. If they reach a specific limit, the IP they are attempting to log from will be blocked for an hour. If they continue with unsuccessful attempts, they will be restricted for 24 hours and 7 days after that.

**Important!**
If you lock yourself out of your admin panel, you can add the following option to your theme’s function.php, reload the site and then remove it once you have gained access. Keep in mind that this will also remove the unsuccessful attempts block for all IP's:

`
add_action( 'init', 'remove_unsuccessfull_attempts_block' );
function remove_unsuccessfull_attempts_block() {
	update_option( 'sg_security_unsuccessful_login', array() );
}
`


== Site Security ==

With this toolset you can harden your WordPress аpplication and keep it safe from malware, exploits and other malicious actions.

= Lock and Protect System Folders =
Lock and Protect System Folders allows you to block any malicious or unauthorized scripts to be executed in your applications system folders. 
If the Lock and Protect System Folders option blocks a specific script used by another plugin on the website, you can easily whitelist the specific script by using the snippets provided below.

Use this one to whitelist a file in the wp_includes folder:
`
add_filter( 'sgs_whitelist_wp_includes' , 'whitelist_file_in_wp_includes' );
function whitelist_file_in_wp_includes( $whitelist ) {

    $whitelist[] = 'file_name.php';
    $whitelist[] = 'another_file_name.php';

    return $whitelist;
}
`

Use this one to whitelist a file in the wp_uploads folder:
`
add_filter( 'sgs_whitelist_wp_uploads' , 'whitelist_file_in_wp_uploads' );
function whitelist_file_in_wp_uploads( $whitelist ) {
    $whitelist[] = 'file_name.php';
    $whitelist[] = 'another_file_name.php';

    return $whitelist;
}
`

Use this one the whitelist a file in the wp_content folder:
`
add_filter( 'sgs_whitelist_wp_content' , 'whitelist_file_in_wp_content' );
function whitelist_file_in_wp_content( $whitelist ) {
    $whitelist[] = 'file_name.php';
    $whitelist[] = 'another_file_name.php';

    return $whitelist;
}
`

= Hide WordPress Version =
When using Hide WordPress Version you can avoid being marked for mass attacks due to version specific vulnerabilities. 

= Disable Themes & Plugins Editor =
Disable Themes & Plugins Editor in the WordPress admin to prevent potential coding errors or unauthorized access through the WordPress editor.

= Disable XML-RPC =
You can Disable XML-RPC protocol which was recently used in a number of exploits. Keep in mind that when disabled, it will prevent WordPress from communicating with third-party systems. We recommend using this, unless you specifically need it.

= Disable RSS and ATOM Feeds =
Disable RSS and ATOM Feeds to prevent content scraping and specific attacks against your site. It’s recommended to use this at all times, unless you have readers using your site via RSS readers.

= Advanced XSS Protection =
By enabling Advanced XSS Protection you can add an additional layer of protection against XSS attacks.

= Delete the Default Readme.txt =
When you Delete the Default Readme.txt which contains information about your website, you reduce the chances of it ending in a potentially vulnerable sites list, used by hackers.

== Activity Log ==

Here you can monitor in detail the activity of registered, unknown and blocked visitors. If your site is being hacked, a user or a plugin was compromised, you can always use the quick tools to block their future actions.

**Important!**
You can set a custom log lifetime ( in days ), using the following filter we have provided for that purpose.

`
add_filter( 'sgs_set_activity_log_lifetime', 'set_custom_log_lifetime' );
function set_custom_log_lifetime() {
    return 'your-custom-log-lifetime-in-days';
}
`

If you need to disable the activity log, you can use the following filter. Keep in mind that this will also disable the Weekly Activity Log Emails.

`
add_action( 'init', 'deactivate_activity_log' );
function deactivate_activity_log() {
    update_option( 'sg_security_disable_activity_log', 1 );
}
`

In case you have disabled the native WordPress Cron Job, and using UNIX cron setup instead, you can add the following rule to your website wp-config.php file in order to have the logs cleared on time:

`
define( 'SG_UNIX_CRON', true );
`

== Post-Hack Actions ==

= Reinstall All Free Plugins =
If your website was hacked, you can always try to reduce the harm by using Reinstall All Free Plugins. This will reinstall all of your free plugins, reducing the chance of another exploit or the re-use of malicious code.

= Log Out All Users =
You can Log Out All Users to prevent any further actions done by them or use.

= Force Password Reset =
Force Password Reset to force all users to change their password upon their next login. This will also log-out all current users instantly.

= WP-CLI Support =

In version 1.0.2 we've added full WP-CLI support for all plugin options and functionalities.
