Zhejiang Security Firewall Parameter Configuration263

In order to ensure the security and stability of the Zhejiang monitoring system, it is necessary to configure the firewall parameters of the monitoring equipment reasonably. The following article will introduce the specific configuration methods of the firewall parameters for the monitoring equipment in Zhejiang.

1. Configure the Firewall Zone

First, you need to configure the firewall zone. The firewall zone is a logical division of the network, which can be used to control the access of different networks. In the monitoring system, the firewall zone can be divided into the following types:
Trusted zone: This zone includes the monitoring center and other trusted devices.
Untrusted zone: This zone includes the monitoring points and other untrusted devices.
DMZ zone: This zone is located between the trusted zone and the untrusted zone. It can be used to place devices that need to access both the trusted zone and the untrusted zone.

After dividing the firewall zone, you need to configure the firewall rules to control the access between different zones.

2. Configure the Firewall Rules

The firewall rules are used to control the access of different networks. In the monitoring system, the firewall rules can be divided into the following types:
Allow rules: These rules allow specific traffic to pass through the firewall.
Deny rules: These rules block specific traffic from passing through the firewall.

When configuring the firewall rules, you need to pay attention to the following points:
The firewall rules are processed in order from top to bottom.
The first matching rule will be applied to the traffic.
If no matching rule is found, the traffic will be blocked.

In the monitoring system, the firewall rules can be used to control the access of the following types of traffic:
Monitoring traffic: This traffic is used for the transmission of monitoring data.
Management traffic: This traffic is used for the management of the monitoring system.
Other traffic: This traffic includes all other traffic that is not related to monitoring.

3. Configure the Firewall Logging

The firewall logging can be used to record the traffic that passes through the firewall. This information can be used for troubleshooting and security analysis.

When configuring the firewall logging, you need to pay attention to the following points:
The firewall logging can be configured to log all traffic or only specific traffic.
The firewall logging can be configured to log the traffic in different formats.
The firewall logging can be configured to send the logs to a specific server.

In the monitoring system, the firewall logging can be used to record the following types of traffic:
Monitoring traffic: This traffic is used for the transmission of monitoring data.
Management traffic: This traffic is used for the management of the monitoring system.
Other traffic: This traffic includes all other traffic that is not related to monitoring.

4. Monitor the Firewall

After configuring the firewall, you need to monitor the firewall to ensure that it is working properly. The following methods can be used to monitor the firewall:
Check the firewall logs: The firewall logs can be used to identify any problems with the firewall.
Use a firewall monitoring tool: A firewall monitoring tool can be used to monitor the firewall in real time.

By monitoring the firewall, you can ensure that the firewall is working properly and that the monitoring system is secure.
