SECURE NETWORK

Network security begins with authentication, which is typically done to use a username and password. This is also referred to as one-factor authentication because it only requires the password to authenticate the user name. Something the user “holds” (such as with a security token or “dongle,” an ATM card, or a mobile phone) is also used with two-factor authentication, and something the user “is” is also used with three-factor authentication (e.g., a fingerprint or retinal scan).

An access control list, such as which services network users are authorized to access, is enforced by a firewall after identification. Despite being effective at blocking illegal entry, this component might overlook potentially hazardous data transmitted from across network, such as Keyloggers or computer worms.

Your network and data are protected from hacks, invasions, and other dangers via network security. This is a broad and inclusive phrase that covers hardware and software options, procedures or policies, and configurations pertaining to network use, accessibility, and overall threat protection.
