Firewall / Internet Security Appliance
Firewalls use one or more of three methods to control traffic flowing in and out of the network:
- Packet filtering - Packets (small chunks of data) are analyzed against a set of filters. Packets that make it through the filters are sent to the requesting system and all others are discarded.
- Proxy service - Information from the Internet is retrieved by the firewall and then sent to the requesting system and vice versa.
- Stateful inspection - A newer method that doesn't examine the contents of each packet but instead compares certain key parts of the packet to a database of trusted information. Information traveling from inside the firewall to the outside is monitored for specific defining characteristics, then incoming information is compared to these characteristics. If the comparison yields a reasonable match, the information is allowed through. Otherwise it is discarded.
Some operating systems come with a firewall built in. Otherwise, a software firewall can be installed on the computer in your home that has an Internet connection.
This computer is considered a gateway because it provides the only point of access between your network and the Internet. Big B does not recommend a software firewall as the reality that software is to vulnerable to becoming disabled, obsolete, corrupted or eventually hacked.
With a hardware firewall, the firewall unit itself is normally the gateway. A good example is the Linksys Cable/DSL router. It has a built-in Ethernet card and hub. Computers in your network connect to the router, which in turn is connected to either a cable or DSL modem. You configure the router via a Web-based interface that you reach through the browser on your computer. You can then set any filters or additional information.
Content Filtering / Parental Control
Business which have Internet access shared among employees are at risk to myriad problems both inside the company network and outside. Malicious websites can install adware / Adware on business computers and bottleneck the network & Internet connection. In addition to productivity loss, restriction to websites can protect the company from legal action.
Families are getting involved with their Internet connections as well. However, managing a tech savvy teen on the web can be tough and far from foolproof.
Among the subject based categories provided in Content Filtering solutions, you will also have control over:
- What Web content their children can access.
- What time of day they are allowed to access the Internet.
- How much time they spend online every day.
- What Internet applications they are allowed to use.
One of the most common shortcomings of software based parental control solutions is that they are relatively easy to bypass. Since parental control software is installed directly on a PC, tech-savvy children can often find information on the Internet or from friends on how to bypass most software parental control. Common techniques include:
- Installing software patches or cracks designed to bypass a specific software package.
- Installing a second operating system to make the PC a dual-boot system (average parents don't even know what that means!)
- Using a CD bootable operating systems such as KNOPPIX Linux, to bypass Windows entirely.
- Inviting a friend with a laptop or Internet ready PDA over.
- Gaining access to a PC in the home which does not have any parental control software installed.
A hardware based solution provides parental control for the entire home by enforcing all the parental controls at the gateway.
Anti-Virus Protection
Protect your network and computers from viruses, worms, Trojan horses, blended threats, SPAM, and other unwanted content. Experts estimate that the Mydoom worm infected approximately a quarter-million computers in a single day in January 2004. (Times Online). Back in March 1999, the Melissa virus was so powerful that it forced Microsoft and a number of other very large companies to completely turn off their E-mail systems until the virus could be contained. The ILOVEYOU virus in 2000 had a similarly devastating effect. That's pretty impressive when you consider that the Melissa and ILOVEYOU viruses are incredibly simple.
Data Protection
Redundant hard drives can be installed on systems which hold critical data. Using Backup strategies can also improve your data security but will be worth their weight during a disaster recovery.
