Besides talking to your kids, officials say there are things to watch out for if you think your child may be engaging in inappropriate activity online.
Warning signs include instances when a child minimizes windows or shuts the computer down suddenly, along with noticing a tendency for the child to isolate him or herself from the rest of the family.
The Sioux City Police Department says it's important to limit the time your kids spend online, check the computer's website history, and have access to their social media accounts.
The computer's location is also an important factor.
"We would recommend that you have the computer out in the open somewhere, either in the living room, a kitchen area somewhere, and have the screen facing the open area so that anybody can walk by and see what's on that screen," said Chad Sheehan, Sioux City Police.
The police department recommends an educational website that can help parents keep their kids safe.
