What are the various non-biometric security measures?

 Companies are using firewalls. A firewall is a combination of hardware and software that controls the flow of incoming and outgoing network traffic and prevents unauthorized communication into and out of the network.

The firewall identifies names, Internet Protocol (IP) addresses, applications, and other characteristics of incoming traffic.

It checks this information against the access rules programmed into the system by the network administrator. There are a number of firewall screening technologies:

Packet filtering examines fields in the headers of data packets flowing between the network and the Internet, examining individual packets in isolation, Stateful inspection determines whether packets are part of an ongoing dialogue between a sender and a receiver.

Network Address Translation (NAT) conceals the IP addresses of the organization’s internal host computer(s) to protect against sniffer programs outside the firewall.

Application proxy filtering examines the application content of packets. A proxy server stops data packets originating outside the organization, inspects them, and passes a proxy to the other side of the firewall.

If a user outside the company wants to communicate with a user inside the organization, the outside user first “talks” to the proxy application and the proxy application communicates with the firm’s internal computer.

Intrusion Detection Systems: These systems detect and deter intruders. In case of a suspicious incident, the device triggers an alert.

Antivirus and Antispyware Software: Most antivirus software is effective only when it is written against a known malware. The antivirus software must be continuously updated to continue to be effective.

Unified Threat Management Systems (UTM): It is an information security term that refers to a single security solution and usually a single security appliance, the provides multiple security functions at a single point on the network
