How to Deal with Corporate Network Monitoring

As technology advances, corporate network monitoring has shifted from traditional physical monitoring to digital monitoring. This article explores common network monitoring methods used by modern enterprises and provides legal privacy protection advice.

The Evolution of Corporate Network Monitoring

The monitoring methods of modern enterprises have shifted from traditional physical monitoring (such as cameras, on-site inspections, etc.) to more sophisticated digital monitoring systems. This transition makes monitoring more covert and cost-effective.

Common Network Monitoring Methods

One of the core methods of corporate network monitoring is tracking through DNS servers. The specific implementation methods include:

Deploying dedicated DNS servers within the corporate network
Forcing the use of corporate DNS through DHCP services
Establishing a correspondence between IP addresses and workstations

The Technical Principles of Monitoring

Even today, with the widespread use of HTTPS, DNS queries are still transmitted in plain text. This means:

All domain name resolution requests will be recorded
Although the specific content accessed cannot be seen, the domain names of the websites visited can be known
Combined with timestamps, employee internet behavior patterns can be analyzed

Solutions for Protecting Personal Privacy

To reasonably protect personal privacy, consider the following solutions:

Use personal mobile networks
Configure private DNS services
Use secure VPN services

Please note: When taking any privacy protection measures, one should comply with relevant laws and regulations and corporate policies.
