Everyday Tools for Internet Security |
Anti-Virus Scanners
Anti-Virus software is made to prevent and remove infection from viruses downloaded from the internet and other sources, and
viruses that exist already on the target system. These products can intercept files as they are downloaded, scan them for viruses
and alert the user that the potential infection has been thwarted. In addition to on-demand scans they also handle scanning of
complete systems for any sign of malware that may have been present prior to installation of the tool.
Internet Filtering Software
Internet Filters stop users from accessing inappropriate material found on the internet, by analyzing the content or visited sites,
and allowing or preventing access depending on the results. Good filters analyze requests for internet sites
as they are initiated by the user and compare them to lists of known illicit websites or keywords. Others allow the requests
to go out but they then analyze the returning data and use intelligent analysis to review the incoming data,
including image scanning, keyword lists etc.
Firewall Software
Firewalls maintain security against hackers and other malicious intruders by monitoring network traffic and preventing
attacks from aross the internet or from a connected network. Many now also intercept outbound messages that originate from malicious software
on the computer; these attacks are more prevalent than ever. The intention is to obtain private data on the computer and send it to a third
party without the user's consent. These invaders can take the form of ActiveX controls, trojans, etc. and firewalls provide security against
such attacks.
Hard Drive Cleaners
These software tools are used to search a computer for adult material that already exists there and help
remove it. This has become more essential because the internet is just one of many paths for illicit material
to find its way onto computer hard drives. With removable storage, USB drives, rewritable CD and DVD media etc.
there are now many more paths for material to arrive through.
