Solution
The common method to protect a network from unauthorized access and attacks is "Regularly updating and patching software".
Here's why:
-
Opening all ports on the firewall: This is not a good practice as it can expose the network to potential threats. Firewalls are used to block unwanted traffic, and opening all ports would defeat this purpose.
-
Using default login credentials for devices: This is also not a good practice. Default login credentials are often well-known and can be easily guessed by attackers. It's important to change default passwords to something unique and strong.
-
Regularly updating and patching software: This is a common and effective method for protecting a network. Software updates often include patches for security vulnerabilities that have been discovered since the last version was released. By regularly updating and patching software, you can protect your network from known threats.
-
Block all ports on Firewall: This is not practical as it would prevent all incoming and outgoing network traffic, including legitimate traffic. While it's important to block unnecessary ports to reduce potential entry points for threats, blocking all ports would likely disrupt normal network operations.
