How is a Database Firewall used?

A firewall is a method designed to prevent unauthorized access to or from a private network. The database firewalls can be applied to both hardware and software, or an arrangement of both.

Database firewalls are often used to thwart unauthorized Internet users from accessing the private networks joined to the Internet, particularly intranets. All messages incoming or outgoing the intranet pass through the firewall, which inspects every message and blocks the ones that do not fulfill the specific security criterion.

The key features of the firewall protection comprise the following:

  • Varied degree of protection based on the location of the computer
    When your system joins a network, the firewall applies a level of security in harmony with the type of network. If you feel like changing the security level allocated, at first, it is possible to do so at any time in the firewall settings.
  • Security of wireless networks (Wi-Fi)
    This blocks invasion trials instigated through wireless networks (Wi-Fi). When an intruder tries to access, a pop-up warning is presented that permits you to instantaneously block the attack.
  • Right to use the network and the Internet
    It states that which programs installed on your computer can have the right to use the network or the Internet.
