Notes

* It does not support the multisite function of WordPress.
* It only supports Apache 1.3, 2.x for Web servers.
* To use the CAPTCHA function, the expansion library “mbstring” and “gd” should be installed on php.
* To use the management page filter function and login page change function, “mod_rewrite” should be loaded on Apache.
* To use the WAF Tuning Support, WAF ( SiteGuard Server Edition ) should be installed on Apache.

There are the following functions.

* Admin Page IP Filter

It is the function for the protection against the attack to the management page (under wp-admin.)
To the access from the connection source IP address which does not login to the management page, 404 (Not Found) is returned.
At the login, the connection source IP address is recorded and the access to that page is allowed.
The connection source IP address which does not login for more than 24 hours is sequentially deleted.
The URL (under wp-admin) where this function is excluded can be specified.

* Rename Login

It is the function to decrease the vulnerability against an illegal login attempt attack such as a brute force attack or a password list attack.
The login page name (wp-login.php) is changed. The initial value is “login_<5 random digits>” but it can be changed to a favorite name.

* CAPTCHA

It is the function to decrease the vulnerability against an illegal login attempt attack such as a brute force attack or a password list attack,
or to receive less comment spam. For the character of CAPTCHA, hiragana and alphanumeric characters can be selected.

* Login Lock

It is the function to decrease the vulnerability against an illegal login attempt attack such as a brute force attack or a password list attack.
Especially, it is the function to prevent an automated attack. The connection source IP address the number of login failure of which reaches
the specified number within the specified period is blocked for the specified time.
Each user account is not locked.

* Login Alert

It is the function to make it easier to notice unauthorized login. E-mail will be sent to a login user when logged in.
If you receive an e-mail to there is no logged-in idea, please suspect unauthorized login.

* Fail Once

It is the function to decrease the vulnerability against a password list attack. Even is the login input is correct, the first login must fail.
After 5 seconds and later within 60 seconds, another correct login input make login succeed. At the first login failure, the following error message is displayed.

* Disable Pingback

The pingback function is disabled and its abuse is prevented.

* Block Author Query

Prevents leakage of user names due to "/?author=<number>" access.

* Updates Notify

Basic of security is that always you use the latest version. If WordPress core, plugins, and themes updates are needed , sends email to notify administrators.

* WAF Tuning Support

It is the function to create the rule to avoid the false detection in WordPress (including 403 error occurrence with normal access,)
if WAF ( SiteGuard Server Edition ) by EG Secure Solutions is installed on a Web server. WAF prevents the attack from the outside against the Web server,
but for some WordPress or plugin functions, WAF may detect the attack which is actually not attack and block the function.
By creating the WAF exclude rule, the WAF protection function can be activated while the false detection for the specified function is prevented.
