How do firewalls protect your data?


Firewalls are designed to safeguard your computer and personal data from a variety of potential threats, including:

  1. Individuals attempting to hack into your system
  2. Malicious programs like viruses and worms spread via the Internet
  3. Unauthorized traffic through your computer caused by viral infections

Firewalls protect your system and data from attacks by unscrupulous individuals and programs, creating a shield between your computer or network and any external security threats. Depending on how a firewall is configured, it can block access from specific locations while at the same time allowing connections from authorized sources. For users who depend on "always on" Internet service through DSL or cable modems, such features are particularly advantageous.
