How does network security generally handle threats?

Network security addresses threats primarily by employing firewalls and encryption. Firewalls act as a barrier between a trusted internal network and untrusted external networks, controlling incoming and outgoing traffic based on predetermined security rules. This helps to prevent unauthorized access and potential attacks from external sources. On the other hand, encryption secures data by encoding it, ensuring that even if data is intercepted during transmission, it cannot be easily read or accessed without the appropriate decryption key. This combined approach enhances the overall security posture of the network, making it more resilient against various forms of cyber threats.

In contrast, ignoring potential vulnerabilities would leave a network exposed to risks, while focusing solely on software solutions would neglect hardware-related security measures. Reducing hardware resources could further compromise security by limiting the capacity for implementing effective protective measures. Therefore, employing a diverse set of tools like firewalls and encryption is essential for robust network security.
