Iseva yewebhusayithi inokukuthintela njani ukuhlaselwa kweCC/ddos? php anti-attack code deployment

Isishwankathelo seli nqakuWordPressUhlaselo lwe-Anti-CC, indlela yokuhlasela yeDDOS.

Injongo yokubhala eli nqaku kukuba abaninziIntengiso ye-Intanethiukusetyenziswa kwabasebenziIwebhusayithi yeWordPress,Iiwebhusayithi zihlala ziphantsi kohlaselo lweCC/DDOS, okubangela ukuba iiseva zewebhusayithi zilayishwe kakhulu kwaye zicothe ukulayisha, ezichaphazelaEzorhweboIndawo yewebhuseoumgangatho.

Ngoku i-CC ihlasela / i-DDOS ihlasela ikakhulu ibiza i-N ezininzi ze-IP, rhoqo ukuhlaziya iphepha elithile lewebhusayithi, ukwenzela ukuba izicelo zomncedisi ziqhubeke, kwaye ekugqibeleni zibangele ukuba iseva ilayishwe kwaye ihla.

Iseva ye-WordPress ye-anti-CC, ikhowudi yokuhlaselwa kwe-ddos

• Umsebenzi oyintloko wale khowudi ilandelayo kukukhomba idilesi ye-IP ethi "ihlaziya iphepha ngaphezu kwamaxesha e-3 okanye ngaphezulu ngokuqhubekayo ngaphakathi kwemizuzwana ye-5" kwidilesi ye-IP yendawo 127.0.0.1.
• Le ndlela iya kuba ngcono ukukhusela ukuhlaselwa kweCC kunye neDDOS.

$_SESSION['ll_times'] = $ll_times;
}else{

$_SESSION['ll_lasttime'] = $ll_lasttime;
}
//现在时间-开始登录时间 来进行判断 如果登录频繁 跳转 否则对session进行赋值
if(($ll_nowtime - $ll_lasttime) < 3){
if ($ll_times>=5){
