Definition and function of proxies

Naproxy

1. basic function of proxies

The core concept of proxies is to forward traffic from a source to a destination with the possibility of changing the source IP or the destination IP.Proxies are useful not only for hiding client IPs, but also for processing and filtering traffic at the network layer (L3) and the application layer (L7). Using proxies allows for load balancing, traffic redirection, access control, and other functions. The proxies themselves usually change the source IP of the traffic, but changing the location is not required for proxies.

2. Differences between proxies and firewalls

Although proxies and firewalls have similar functions in some cases (e.g., filtering traffic and blocking malicious IPs), they work at different levels. Proxies usually work at the application layer and are able to deeply analyze and process specific application protocols (e.g., HTTP, FTP, etc.), while firewalls work more at the network layer and deal with basic filtering of IPs, ports, and protocols.

3. Proxies usage scenarios

Proxies allow you to hide your real IP, especially when multiple services share the same IP, and use virtual hosts to direct traffic to different services.

Proxies can also be used as traffic filters, allowing users to define more specific traffic rules, especially for blocking unwanted application protocols (e.g. P2P traffic) in enterprise networks.

Proxies can also cache frequently accessed resources, reducing bandwidth consumption.

Security and Privacy

1. Challenges posed by encrypted traffic

With the popularity of HTTPS and encrypted communications, proxies face difficulties in performing traffic filtering. Encrypted traffic makes it impossible for proxies to view the content of the transmission and therefore cannot filter based on the content. new encryption protocols such as DNS over HTTPS further exacerbate this challenge.

2. Proxies on a LAN

If the proxies and clients are located on the same LAN and share the same public IP, the proxies are relatively less useful because they do not effectively hide the source IP or alter the traffic path. The value of proxies in this case is mainly in traffic management and service distribution.

Applications of Reverse Proxies

1. Role of Reverse Proxies

Reverse proxies are usually deployed between public servers and internal servers, and are mainly used to protect the internal network from external attacks and filter malicious requests. It can also be used for traffic load balancing to distribute user requests to different internal servers. The difference between a reverse proxy and a traditional proxy is that it proxies server-side traffic rather than client-side traffic.

2. Functional overlap between reverse proxies and firewalls

A reverse proxy can act like a firewall, scanning traffic passing through it and blocking non-compliant requests. However, its focus is more on protecting internal servers from direct exposure to external networks by way of proxies. Reverse proxies can also provide security measures such as authentication and access control.

Usage in Personal Home Networks

1. Proxies in home networks

The use of proxies and reverse proxies in a home environment can improve security. For example, proxies can be configured to monitor the network behavior of family members, filter undesirable content, and avoid IP leakage.

2. Combined use of virtual private networks and proxies

When dealing with applications that may leak local IPs (such as Kodi), the use of proxies or reverse proxies in combination with a virtual private network can be effective in ensuring anonymity and security of traffic. Privacy can be improved by ensuring that the application connects only through the VPN and avoids direct access to the Internet.

Summarizing

These discussions have demonstrated the diverse capabilities of proxies and reverse proxies, especially in security and traffic management. While proxies can change IPs and perform traffic filtering, their role in modern encrypted communications is limited. Reverse proxies, on the other hand, are more often used to protect internal services and enable load balancing. Both can be used in home networks and enterprise environments to enhance network security, hide real IPs, and optimize traffic management.

The above text focuses on the relationship between proxies and reverse proxies, and the following are some common expansion questions:

1. Proxies and Security

Users will be curious if they are using a proxy server in their home network with regards to its security. If the proxies and devices are located in the same network, does it still provide the same security as a remote proxy.

2. The role of proxies

According to John Klos, proxies are not directly related to security. Proxies are primarily used for purposes such as IP sharing and load balancing, not for improving security. Proxies only provide privacy protection if there are security holes in the system itself.

3. Privacy and Security

Another user (BlackBird2a) argued that proxies do correlate with security because they can change the IP from which traffic originates, thus improving privacy protection. For example, with proxies, a user's IP can be changed to where the proxy server is located, which makes it possible for accessing services to only see the proxy's IP and not be able to trace the user's real IP.

4. Firewalls and security

John Cross further explains that firewalls are indeed an important tool for improving security, but relying on firewalls alone does not fundamentally improve security. If there are security holes in the system itself, an external firewall will not fix them. The security provided by proxies is viewed as an additional layer that helps protect against external threats.

5. The right security policy

John Cross also gave Windows as an example, noting that by default, Windows operating systems are poorly secured, with many insecure services enabled by default that must be protected by a firewall. However, a better security strategy is to ensure that there are no security holes in the system itself, rather than relying solely on firewalls or proxies to compensate for security flaws.

Proxies add privacy protection and protection against external threats, but they are not a one-size-fits-all solution for improving security. The fundamental approach to securing a system should be to ensure that the system itself is free of vulnerabilities, rather than relying solely on proxies or firewalls to compensate for security flaws.
