Apache has always been the top three Web server software in the world. Enterprises need to comprehensively consider the security of their Web applications to ensure they can respond to network threats such as denial of service (DoS) attacks, traffic eavesdropping, and data leakage, this ensures the security of enterprise portal websites.
In addition to the industry's popular firewalls, IDS/IPS Intrusion Detection Systems/intrusion defense systems), WAFWeb application firewalls), and

According to relevant information, a large number of servers are still using IIS to provide Web Services, and even compete to occupy the Apache market. In today's increasingly severe Web threats, we certainly need to use anti-virus, firewall, UTM, NAC and other means to enhance network security. However, building a honeypot correctly is also an essential task for dealing with hackers.
What is a honeypot? In short, a honeypot is a

2.1Lab Area Overview
The sample area of the experiment is the old city of xuchang City, Henan Province. The area is 1.8 square kilometers, with thousands of individual buildings. The ancient and modern buildings in the area coexist, and there is a large area of water and green space, fully reflecting the complexity and diversity of general cities, it is very representative.

The Cartesian coordinate system is defined as a "flat" coordinate system following the curvature of the Earth. it's not flat in the sense that it usually follows the Earth's curvature in one direction and has a known scale-error in the other direction relative to the distance of the origin. the most well-known coordinate system is the Universal Transverse Mercator (UTM), but surveyors define their own little local flat coordina

In 1977, the US National Bureau of Standards and Regulations officially implemented the US Data Encryption Standard DES, disclosed its encryption algorithm, and approved the use of it for non-confidential organizations and commercial confidential communications. Then DES became the world's most widely used encryption standard. The encryption and decrypti

In general, if there is a ANR occurrence, the system will generate trace files in the/data/anr/directory, by analyzing the trace file, you can locate the cause of the ANR. There are many reasons for the ANR, such as high CPU usage, no timely response to events, deadlocks, and so on, which shows how to analyze
