To maximize and optimize the experience of using your Lightsail instance, it is recommended that you have the flexibility to open up your firewall when necessary to precisely control network traffic. By carefully configuring your firewall rules, you can achieve optimal performance and efficiency of your network connections while maintaining the security of your system.

When developing your firewall policy, be sure to consider the security needs of your applications and data. You can grant access to specific IP addresses or IP ranges based on specific business scenarios to enable targeted network communications. At the same time, you can plan port rules wisely to allow necessary service traffic in and out while limiting potential risks.

Not only that, but as network threats and security risks continue to evolve, it is recommended that you review and update your firewall policies regularly. This helps maintain consistency with security best practices as well as adapt to changing security threats. By regularly monitoring firewall activity logs, you can detect abnormal activity early and take appropriate responsive action.

In summary, with advanced firewall configurations and continuous security policy updates, you can take full advantage of the performance of your Lightsail instances while safeguarding your system to ensure that your business continues to run stably.
