Threats to computer security 37
Kaspersky Internet Security stops network attacks without disrupting network
connections, by using special firewall databases. These databases contain
records identifying characteristic IP data packets sent by various hacking
programs. The application analyzes network connections and blocks in them any
dangerous IP packets.
BANNERS
Banners or ads are links to an advertiser's website, commonly displayed as
images. Displaying banners on a website does not impose any threat to the
computer's security, but is still considered an interference to the computer's
normal operation. If banners flicker on the screen they affect working conditions
and decrease efficiency. The user is also distracted by irrelevant information, and
following the banner links increases the internet traffic.
Many organizations prohibit displaying banners in interfaces as part of their data
security policies.
Kaspersky Internet Security blocks banners, based on the URL of the website to
which the banner has a link. It uses updatable Banner Ad Blocker databases
which contain a list of URLs of Russian and foreign banner networks. The
application processes links of the web page being loaded, compares them to the
address list in the databases and if it finds a match, it deletes the link to this
address from the site and continues loading the page.
