Blog 1: The Importance of Firewalls in SME Cybersecurity

Firewalls are a vital defense against external threats. They serve as a barrier between your devices and networks you don't control. Here are some things to consider when it comes to firewalls:

1. Correct Configuration: Ensure that all your devices and environments have properly configured firewalls. This includes the Windows firewall and a firewall separating your internal network from the outside world.
2. Protect the Administrative Interface: The interface used to administer the firewall should be safeguarded with robust security measures, such as complex passwords and multi-factor authentication.
3. Change Default Passwords: Many devices come with default passwords, which are often widely known. It's essential to change these default passwords to enhance security.
4. Default Deny: Configure your firewall to deny traffic by default. This means that all network traffic is blocked unless explicitly allowed, preventing unexpected data breaches.

By implementing these firewall measures, small organizations can significantly enhance their cybersecurity defenses.
