tomcat - AWS Data Transfer issue -

-

i've spot problem in aws cloud. i'm getting big bill data transfer(month data transfer out). ec2 instance contains tomcat server mobile application. have 1.5k users , use rest webservices. i've setup benchmarks , showed send 1 - 3gb per month responses. got bill 9.5 tb data transfer out. few days ago monitoring instance , see server output trafic approx 200gb/day. don't know, maybe hacked, use security groups on aws , users have access 80 port , ip has access 22(ssh) only. can find solution? or maybe have suggestion can be? lot.

i'd enable access logging on tomcat, , ensure isn't data coming out of tomcat. should able sum amount of traffic access logs , determine if tomcat source.

i assume don't have apache in front, , you're using elastic load balancer translate 80 8080? if have apache or similar in front, enable access logging on that. don't running tomcat root on port 80.

what other components using in setup? check isn't automated backup solution!

hope helps,
