    A personal firewall is an application which controls
    network traffic to and from a computer, permitting or denying
    communications based on a security policy.

    A personal firewall differs from a conventional firewall in terms of
    scale. Personal firewalls are typically designed for use by end-users.
    As a result, a personal firewall will usually protect only the computer
    on which it is installed.

    Many personal firewalls are able to control network traffic by prompting
    the user each time a connection is attempted and adapting security
    policy accordingly. Personal firewalls may also provide some level of
    intrusion detection, allowing the software to terminate or block
    connectivity where it suspects an intrusion is being attempted.

    Common personal firewall features:

    * Alert the user about outgoing connection attempts
    * Allows the user to control which programs can and cannot access
    the local network and/or Internet
    * Hide the computer from port scans by not responding to unsolicited
    network traffic
    * Monitor applications that are listening for incoming connections
    * Monitor and regulate all incoming and outgoing Internet users
    * Prevent unwanted network traffic from locally installed
    applications
    * Provide the user with information about an application that makes a
    connection attempt
    * Provide information about the destination server with which an
    application is attempting to communicate

    Criticisms

    * Instead of reducing the number of network-aware services, a
    personal firewall is an additional service that consumes system
    resources and can also be the target of an attack, as exemplified by the
    Witty worm.
    * If the system has been compromised by malware, spyware or similar
    software, these programs can also manipulate the firewall, because both
    are running on the same system. It may be possible to bypass or even
    completely shut down software firewalls in such a manner.
    * The high number of alerts generated by such applications can
    possibly desensitize users to alerts by warning the user of actions that
    may not be malicious (e.g. ICMP requests).
    * Software firewalls that interface with the operating system at the
    kernel mode level may potentially cause instability and/or introduce
    security flaws and other software bugs.
