Network security is important in today's digital age to protect against various threats such as crashing systems, unauthorized access of unencrypted data, traffic redirection, fraud, and malicious software. Strong passwords, encryption, firewalls, security policies, anti-virus software, and backing up data can help secure a network. System administrators should limit network access, and users should practice safe password management and email habits to avoid security risks.
