示例代码
例
This code logs suspicious multiple login attempts.
bad PHP
function login($userName,$password){
if(authenticate($userName,$password)){
return True;
}
else{
incrementLoginAttempts($userName);
if(recentLoginAttempts($userName) > 5){
if(recentLoginAttempts($userName) > 5){
writeLog("Failed login attempt by User: " . $userName . " at " + date('r') );
}
}
}
This code only logs failed login attempts when a certain limit is reached. If an attacker knows this limit, they can stop their attack from being discovered by avoiding the limit.
