In network applications, public IP is an important concept. A public IP address is an IP address that can be directly accessed on the Internet and is the entrance to network communication. However, public IP addresses are also vulnerable to hackers, so they need to be set up to ensure security.
1.Enable encryption: When you set a public IP address, you need to enable encryption to prevent hacker attacks. WPA2 encryption is generally used to protect the network.
2.Change the default password: The default password of the router can be easily cracked, so you need to change the default password to strengthen the network security.
3.Update your router's firmware regularly: There are security vulnerabilities in your router's firmware that hackers can exploit to attack your network. Therefore, it is necessary to update the router firmware regularly to fix the security.
4.Deploy a firewall: Use a firewall to protect your network from unauthorized access and attacks. By setting policies, the firewall can block specific access requests and ensure the security of intranet servers.
5.Hide public IP addresses: Hackers usually scan public IP addresses to find potential targets. By using a VPN or service, you can hide your public IP and thus reduce the risk of being attacked.
6.Replace high-risk ports: For some common hacker attack ports, such as remote desktop port 3389 and database port 1433, try not to map them directly or enable DMZ, which may increase the risk of being attacked.
7.Data backup: Develop a good Xi of backing up your data regularly in case of data loss in the event of a server failure. At the same time, backing up data can also quickly restore the system in the event of an attack.
8.Regularly monitor network traffic: By regularly monitoring network traffic, you can detect abnormal traffic and potential attacks in a timely manner.
A NAS is a network storage device that can connect to computers and other devices over a network. NAS can be used to store data, back up data, and share data. When using NAS, you need to set access permissions to prevent unauthorized access.
Public IP settings are an important step to protect network security, and you need to set DHCP, port mapping, firewall and other functions, pay attention to enabling encryption, changing the default password, and regularly updating the router firmware. When you use NAS, you need to set access permissions to ensure data security.
