Final answer:
To prevent future security breaches through network switches, a company should enforce strong password policies, enable two-factor authentication, and conduct regular security audits.
Step-by-step explanation:
In light of the recent security breach through a network switch using default credentials, a company should take several steps to improve security and prevent future incidents. Increasing security for individuals and companies involves multi-faceted strategies, such as stronger password policies and authentication methods, and an ongoing commitment to education and awareness.
The use of default credentials is a significant security vulnerability. To mitigate this, the company should implement strong password policies that require complex and unique passwords. This would involve creating guidelines for password strength, such as minimum lengths, the inclusion of numbers, symbols, and both upper and lower case letters, and regularly scheduled changes.
A crucial layer to add is two-factor authentication (2FA). 2FA requires a second form of verification beyond just the password, such as a code sent to a user's phone, which significantly decreases the likelihood of unauthorized access.
To ensure the ongoing integrity of network security, the company should conduct regular security audits. These audits will help identify any current vulnerabilities, including poor password practices or outdated systems, and ensure that security policies are being effectively implemented and followed.
While not explicitly mentioned in the options provided, education on security best practices and the importance of not using default credentials is also imperative. This cultural shift can help prevent employees from making common security mistakes.
