1 accept all related and established states
2 accept all packets from the icmp protocol (ping etc.)
3 accept everything coming to the loopback interface (lo)
4 accept ssh traffic – port 22 on the tcp protocol
5 accept http traffic – port 80 on the tcp protocol
6 accept https traffic – port 443 on the tcp protocol
7 drop all other packets.

Those IPs are in private IP space, so I doubt it. How did you determine they are “attacking” you?
