README

This tool designed for simple limiting some user requests. It makes it easy to add some protection from DB ddos or bruteforce attack.

INSTALL

1: install via composer

composer require ircop/antiflood

2: add service provider to providers array in config/app.php:

Ircop\Antiflood\AntifloodServiceProvider::class,

3: add facade alias to aliases array in config/app.php:

'Antiflood' => Ircop\Antiflood\Facade\Antiflood::class,

Usage

Checking for record existance with given ident.

Ident can be ip-address, login, anything unique.

$maximum - is maximum allowed value for this ident. Default is 1.

\Antiflood::check( $ident, $maximum = 1 );

// Or with IP identity

\Antiflood::checkIP( $maximum = 1 );

Putting record for given ident on given $minutes:

\Antiflood::put( $ident, $minutes = 10 );

// Or with IP identity

\Antiflood::putIP( $minutes = 10 );

Examples:

Limiting wrong login attempts for given IP address:

This example limiting wrong login attempts from one ip-address to 5 tryes per 20 minutes:

public function postLogin()
{
	$key = $_SERVER['REMOTE_ADDR'];
	
	// If this ip has >= 5 failed login attempts in last 20 minutes, redirect user
	// back with error:
	if( \Antiflood::check( $key, 5 ) === FALSE )
		return redirect()->back()->withErrors(['Too many login attempts! Try again later.']);
	
	// ....
	// ....
	// ....

	// After failed login put user ipaddr to antiflood cacte on 20 min.
	// If there is no records with this ident, record will be added with value=1, else
	// it will be increased.
	\Antiflood::put( $key, 20 );
}

Limiting password recovery for 1 try per 30 min.

This code shows how to limit some functions like email, etc. to prevend flood from our server, for example.

public function postPasswordRecover()
{
	$key = \Input::get('email');
	if( \Antiflood::check( $key ) === FALSE )
		return redirect()->back()->withErrors(['.....']);
	
	// ....
	// ....
	// ....

	\Antiflood::put( $key, 20 );
}
