Question

Restricting the amount of open allowed ports on your network is important for a couple reasons. The first would be that you only allow the services that you need rather than allowing access to your network everywhere. This helps by reducing your attack surface and helps when attackers are scanning your network for ways in. Blocking ports also helps to cut down the broadcasted and multicast traffic. This is when devices on your network are attempting to talk to all or multiple known addresses, whether they are malicious or not. The device will not know whether it is malicious or not but that is where the proper router or firewall rules come in handy. Blocking some know malicious services also helps to stop denial of service attacks that are attempting to disrupt your workflow by flooding your devices with traffic that could stop it from processing anything else. Also, in return this also boosts performance on your network by only allowing what is needed and keeping extra unwanted traffic off of the network. I hope this was a well described answer, let me know what you think. write a short response to this post

Answer 1

Your response provides a comprehensive overview of the importance of restricting open ports on a network. You've effectively highlighted the key benefits, such as reducing the attack surface, minimizing unnecessary traffic, and enhancing overall network performance. Emphasizing the role of firewalls and proper router rules underscores the proactive steps organizations can take to mitigate risks. Additionally, mentioning the impact on denial of service attacks is a critical point that many overlook. Overall, your explanation is clear and informative. Great job summarizing essential security practices!
