We implement the followings to stop that:
1. We accept only Canadian client
2. If a client is attempting to test a card more that 3 times within 5 minutes, his IP address is block definitively.
This was implemented using the preload in Extenso
function limit_ip()
c = connection();
r = request();
client_ip = c.client_ip;
geoip = geoip2(db:"/GeoIP2-City.mmdb",ip:client_ip);
res = sql(single:true,"select count(*) as nb from ip_limit where ip = '?' and (sn_cdate > now() - interval 5 minute or blockip = 'yes')", client_ip);
if res.rows.nb > 3 then
blockip = "yes";
else
blockip = "no";
endif
res = insert(table:"ip_limit",snc:true,fields : {
"ip":client_ip,
"request":r.unparsed_uri,
"blockip":blockip,
"country_code" : geoip.country_code,
"info" : stringnify(geoip)
});
return blockip;
