What does F-Secure Security Services Personal Firewall mean, and what is a Firewall?
F-Secure Security Services has built-in Firewall (Personal Firewall), that protects you when other users are trying to intrude on your workstation and prevents hacking by denying port scans on your computer. There are advantages to having a F-Secure Security Services Personal Firewall over a traditional Firewall: a traditional Firewall protects the entire network from outside attacks, whereas the F-Secure Security Services Personal Firewall protects individual computers by monitoring inbound/outbound connections from/to unknown sources plus it has an advanced intrusion detection system.
