Children present unique security risks when they use a computer - not
only do you have to keep them safe, you have to protect the data on
your computer. By taking some simple steps, you can dramatically
reduce the threats.
What unique risks are associated with children?
When a child is using your computer, normal safeguards and security
practices may not be sufficient. Children present additional
challenges because of their natural characteristics: innocence,
curiosity, desire for independence, and fear of punishment. You need
to consider these characteristics when determining how to protect your
data and the child.
You may think that because the child is only playing a game, or
researching a term paper, or typing a homework assignment, he or she
can't cause any harm. But what if, when saving her paper, the child
deletes a necessary program file? Or what if she unintentionally
visits a malicious web page that infects your computer with a virus?
These are just two possible scenarios. Mistakes happen, but the child
may not realize what she's done or may not tell you what happened
because she's afraid of getting punished.
Online predators present another significant threat, particularly to
children. Because the nature of the internet is so anonymous, it is
easy for people to misrepresent themselves and manipulate or trick
other users (see Avoiding Social Engineering and Phishing Attacks for
some examples). Adults often fall victim to these ploys, and children,
who are usually much more open and trusting, are even easier targets.
The threat is even greater if a child has access to email or instant
messaging programs, visits chat rooms, and/or uses social networking
sites (see Using Instant Messaging and Chat Rooms Safely and Staying
Safe on Social Network Sites for more information).
What can you do?
- Be involved - Consider activities you can work on together,
whether it be playing a game, researching a topic you had been
talking about (e.g., family vacation spots, a particular hobby, a
historical figure), or putting together a family newsletter. This
will allow you to supervise your child's online activities while
teaching them good computer habits.
- Keep your computer in an open area - If your computer is in a
high-traffic area, you will be able to easily monitor the computer
activity. Not only does this accessibility deter a child from
doing something she knows she's not allowed to do, it also gives
you the opportunity to intervene if you notice a behavior that
could have negative consequences.
- Set rules and warn about dangers - Make sure your child knows the
boundaries of what she is allowed to do on the computer. These
boundaries should be appropriate for the child's age, knowledge,
and maturity, but they may include rules about how long she is
allowed to be on the computer, what sites she is allowed to visit,
what software programs she can use, and what tasks or activities
she is allowed to do. You should also talk to children about the
dangers of the internet so that they recognize suspicious behavior
or activity. The goal isn't to scare them, it's to make them more
- Monitor computer activity - Be aware of what your child is doing
on the computer, including which web sites she is visiting. If she
is using email, instant messaging, or chat rooms, try to get a
sense of who she is corresponding with and whether she actually
- Keep lines of communication open - Let your child know that she
can approach you with any questions or concerns about behaviors or
problems she may have encountered on the computer.
- Consider partitioning your computer into separate accounts - Most
operating systems (including Windows XP, Mac OS X, and Linux) give
you the option of creating a different user account for each user.
If you're worried that your child may accidentally access, modify,
and/or delete your files, you can give her a separate account and
decrease the amount of access and number of privileges she has.
If you don't have separate accounts, you need to be especially
careful about your security settings. In addition to limiting
functionality within your browser (see Evaluating Your Web
Browser's Security Settings for more information), avoid letting
your browser remember passwords and other personal information
(see Browsing Safely: Understanding Active Content and Cookies).
Also, it is always important to keep your virus definitions up to
date (see Understanding Anti-Virus Software).
- Consider implementing parental controls - You may be able to set
some parental controls within your browser. For example, Internet
Explorer allows you to restrict or allow certain web sites to be
viewed on your computer, and you can protect these settings with a
password. To find those options, click Tools on your menu bar,
select Internet Options..., choose the Content tab, and click the
Enable... button under Content Advisor.
There are other resources you can use to control and/or monitor
your child's online activity. Some ISPs offer services designed to
protect children online. Contact your ISP to see if any of these
services are available. There are also special software programs
you can install on your computer. Different programs offer
different features and capabilities, so you can find one that best
suits your needs. The following web sites offer lists of software,
as well as other useful information about protecting children
