Dipakai di mana ini, kok sampai rawan kayak gitu ? Warnet ? Hotspot ?
Coba bantu dengan yang ini =

Code: Select all

#Protect from ip_spoofing
echo "1" > /proc/sys/net/ipv4/conf/*/rp_filter

# Protect from SYN_flood_attack
echo "1" >  /proc/sys/net/ipv4/tcp_syncookies

#Ignoring all ICMP echo request
echo "0" > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts

# Reject all ICMP redirect"
echo "0" > /proc/sys/net/ipv4/conf/*/accept_redirects
echo "0" > /proc/sys/net/ipv4/conf/*/send_redirects

#Protect from MITM"
echo "1" > /proc/sys/net/ipv4/conf/*/secure_redirects

#ping request limitation
iptables -I FORWARD -i $NIC -p icmp --icmp-type echo-request -m limit --limit 1/m --limit-burst 10 -j ACCEPT
iptables -A INPUT -i $NIC -p icmp --icmp-type echo-request -m limit --limit 1/m --limit-burst 10 -j ACCEPT
Install juga arpon

Code: Select all

apt-get install arpon

saya kira klo menghambat ddos ngak bisa tuchh
kecuali ente punya server tersendiri buat ngeredam ddos tersebut..
lagian buthh biaya besar juga kan hekekekekk.....
