To prevent specific programs from being connected to the network can be achieved through system firewalls or third-party tools. 1. Windows users can use their own firewall, create new rules in the "outbound rules" to select the program path and set "block connection"; 2. Third-party tools such as GlassWire or NetBalancer provide graphical interfaces that are more convenient to operate, but pay attention to source reliability and performance impact; 3. Mac users can control networking permissions through the command line with pfctl or using LittleSnitch and other tools; 4. A more thorough way is to use the off-network whitelist strategy to prohibit all programs from being connected to the network by default and only allow trusted programs to access. Although the operation modes of different systems are different, the core logic is consistent, and attention should be paid to the details of the path and scope of the rules taking effect.
Sometimes you may not want a program to access the network, such as to protect privacy, reduce bandwidth usage, or prevent background updates. The good news is that most systems provide ways to prevent specific programs from being connected to the network.
1. Use Firewall Settings (Windows)
The firewall that comes with Windows is actually very powerful and allows you to fine-grained control of network permissions of each program. The operation steps are as follows:
- Open Control Panel → Windows Defender Firewall → Click Advanced Settings on the left
- Click "New Rules" in "Outbound Rules"
- Select "Programs" and browse to find the installation path of the program you want to limit
- After the settings are completed, select "Block connection" in "Operation"
- Give the rule a name and remember to apply it to all network types (domain, dedicated, public)
In this way, the program cannot actively connect to the network. If you want to restore access permissions in the future, you just need to find the corresponding entry in the outbound rule and disable it.
2. Third-party tools: more convenient but need to pay attention to safety
If you don’t like to mess with system settings, you can also use some third-party software to implement similar functions. For example, GlassWire or NetBalancer, they usually provide a graphical interface that can prevent programs from being connected to the Internet with one click.
The advantage of using this type of tool is that it is simple to operate and has strong visualization, which is suitable for those who do not want to move the rules of the system. However, the following points need to be paid attention to:
- Make sure the source is reliable when downloading and avoid the introduction of malware
- Some tools are paid, and the free version may be limited
- They themselves require certain permissions to run and may have a slight impact on performance
3. What should Mac users do?
There is no direct "outbound rules" setting on Mac like Windows, but you can control it indirectly through the included "App Firewall". Although it can only control whether inbound connections are allowed by default, more fine-grained control can be achieved through the command line and pfctl .
An easier way is to use a third-party tool, such as Little Snitch , which can tell you clearly which program is trying to connect to the network and let you decide whether to let it go. Suitable for users who often need to carefully control network access.
4. A more thorough way: strategy for disconnecting the network and whitelisting
If you are a person who is particularly sensitive to privacy, you can also consider the reverse idea: by default, disconnect the network permissions of all programs and allow only a few trusted programs to be connected to the Internet.
This can be achieved on Windows by batch creating outbound rules; on Mac, it relies on third-party tools. Although setting up troublesome points at the beginning, once completed, you can fully control which programs can access the Internet and which cannot.
Basically these are the methods. Different operating systems have different approaches, but the core logic is the same: restrict the network access of the program through a system firewall or third-party tools. It is not too difficult to operate, but it is easy to ignore details, especially the path settings and the scope of the rules taking effect. If you check it a few times, you won’t make any mistakes.

What is AI
Jun 26, 2025 pm 09:01 PM
The core of artificial intelligence is algorithms, especially models that can learn laws from data, such as deep learning. It trains the system through a large amount of data, allowing it to make judgments on new situations, such as face recognition and chatbots. AI is not really intelligent, but statistical methods that mimic human behavior. Common applications include voice recognition (such as Siri), image recognition (such as Alipay face-scanning payment), recommendation systems (such as TikTok and Taobao recommendations), and autonomous driving. AI's capabilities have boundaries, it can only work within the scope of training data, has no real awareness, and relies on a large number of computing resources. When looking at AI, it should be rational. It is an efficient tool but not perfect. It can be used to improve efficiency, but it also needs to be wary of its limitations.
