Why Should You Use a Firewall

Internet Security- Why Should You Use a Firewall?

What is a firewall and how it will protect your internet security?

A

firewall is usually part of the internet router and basically works by passing traffic between

secure and insecure areas.

There are to kinds of firewalls: proxy servers and packet filters. Proxies are generally

more expensive than packet filters.

Computers are identified by IP numbers a firewall can tell if a source is legitimate by comparing

it to a set of rules that it employs. With a packet filter, the firewall won't let in sources that do

not pass the rules. It more or less stands guard over your computer and won't let things pass

through that do not adhere to its standards.

While firewalls are meant to keep things coming in, in some rare cases it can actually prevent

users from getting out as well. This can be frustrating when you are trying to visit a site that

you know is secure but for some reason your firewall has a problem with it and won't let you

access it.

If this becomes a major hindrance, you can reconfigure your firewall settings. Of course, if you

are part of an Intranet, such as at a place of business, there is little that you can do unless

you, yourself, have access to the main computer and passwords. If you do have access,

owever, you can always add the site that you are trying to access as a 'safe site” so that the

firewall will let you in in the future.

You can purchase internet security programs that contain firewalls. It is best to do some

research on them first to get a good feel of what you are purchasing. Some are created superior

to others. If you get a good program, it should also come with some adware and spyware

blockers as well, and perhaps an anti-virus program. Of course, most good anti-virus programs

also come with firewalls.

A

lthough people often bemoan firewalls and the fact that they try to keep people out of sites that

are sometimes legitimate, they can be a great way to protect your computer from harmful

attacks. If you own and operate a business and have employees accessing the internet they can

be especially helpful, too. It can be difficult to protect your internet security when you are dealing

with multiple internet users. It's hard enough being safe yourself!

Internet security-Signs That Your Child's Safety Might Be Compromised

A

lthough you do everything you can to protect your child, sometimes things get past parents

and your child's internet security protection is compromised nonetheless. So how will you

know if there is something going on with your child? The following is a list of signs to watch for

that might indicate your child is suffering from internet related concerns.

1

.Your child turns off the computer the minute you walk into the room. They might have been

catting with their crush or significant other, or been been chatting with their best friend about

something that they thought should be private. Or, they could have been looking at an

inappropriate website. For this reason, you might want to invest in a tracking tool that creates

logs of your child's internet activity that you can review.

2.Your child receives standard mail or packages from people you don't know. It is possible that

they ordered something online. Ask them and then check your bank account or credit cards.

However, sometimes predators do get online and pretend to be something that they are not. In

some cases, they send their victims gifts in order to get them to become beholden to them.

Open any packages that you weren't expecting. In some cases, it is better to ask for forgiveness

than permission.

3

.You find pornography on your child's computer. While it was true that growing up you might have

sneaked a look at Playboy or something similar, Internet pornography can be difficult to get a grasp

on. It is rampant and much of it is fairly different than the almost chaste images seen in Playboy.

Some of it is also “deviant” pornography that includes bestiality and even child pornography.

Therefore, the content should be monitored and communication should exist.

4

.Your child becomes withdrawn. Sex offenders and other people who prey on children do

their best to upset family interactions. If your child tells them a problem that they are having at

ome, the person will often try to make that problem appear larger in order to make the child

more upset at the parent or sibling in an attempt to drive a wedge through the family itself. This

is to gain more control of the child.

5

.Your child spends a lot of time on the computer, especially at night. Invest in a time

control device that limits the amount of time they can spend on the internet at once.
