To improve the security of the switch and avoid breaches in the future, the company should change default credentials, disable unused features, implement strong access controls, enable logging and monitoring, and regularly update firmware.
To improve the security of the switch and avoid such breaches in the future, the company should take the following steps:
Change default credentials: The company should immediately change the default usernames and passwords of the switch to unique and strong credentials that are not easily guessable.
Disable unused features: Disable any unnecessary features or services on the switch to reduce the potential attack surface.
Implement strong access controls: Configure the switch to only allow authorized users to access it. This can be done by enabling authentication mechanisms like RADIUS or TACACS+ and implementing role-based access control.
Enable logging and monitoring: Set up logging and monitoring on the switch to detect any suspicious activities or unauthorized access attempts.
Regularly update firmware: Ensure that the switch firmware is up to date with the latest security patches to fix any known vulnerabilities.
The probable question may be:
A company recently faced a security breach through its network switch. They learned that the attacker was able to access the switch using the default credentials. What steps should the company take to improve the security of the switch and avoid such breaches in the future?
