Disabling unused ports and interfaces.
Securing administrative access.
Router hardening means that the router is secured against attacks as best as possible. Router hardening is one among the three areas of router security that must be maintained to secure an edge router at the network perimeter. Basically, router hardening secures from tough-to-crack passwords, to the shutting down of unnecessary interfaces, ports, and services. Look for any unused router interfaces and disable them by issuing the shutdown command. Disabling unused services typically include BOOTP, CDP, FTP, TFTP, PAD, and a few others. You can also disable administrative and management protocols currently not being like HTTP or HTTPS, DNS, and SNMP.
The reason nonessential protocols are a security issue that you should be concerned about is that: A. nonessential ports provide additional areas of attack.
<h3>What is information security?</h3>
Information security can be defined as a preventive practice which is typically used to protect an information system (IS) that use, store or transmit information, from potential theft, attack, damage, or unauthorized access, especially through the use of a body of technologies, encryption, frameworks, processes and network engineers.
In Cyber security, the reason nonessential protocols are a security issue that an end user should be concerned about is that nonessential ports would provide additional areas of attack because all protocols have weaknesses based on the principle of least privilege.
