For ordinary Internet users, each CDN node is equivalent to a website server placed around it.

The working principle of CDN is to cache the resources of your origin site on CDN nodes located all over the world.

This section will use this as a starting point to focus on various security risks in the cloud.

New types of attacks on the cloud environment may not have attracted the attention of the security team, but the impact of these attacks may be catastrophic.

When using cloud technology, ensuring the security of sensitive and valuable data is a top priority.

Large-scale cloud storage systems face contradictory requirements: the system needs to compress data to save storage space overhead; users want to store data encrypted for data security and privacy considerations.

This article will only share some specific experiences for website backup. Hope it will be helpful to the stationmaster students.

Every data product will have it, because we must prepare storage resources in advance for the amount of data that may be generated in the future.

Replication (Replication) is a technology that copies a set of data from one data source to one or more data sources.

In the era of cloud and big data, the massive increase in data capacity has brought new challenges to data storage and protection.

The benefits of deduplication during backup are obvious, and it has become the mainstream technology in the industry.

For staff responsible for data backup on multiple systems, it is strongly recommended that they use a strong strategy. This tip provides them with seven rules for an effective data backup process.

The author has been paying attention to the security analysis of Webshell, and recently I will share with you my experience during this period.

A brief summary can be found, there are at least 3 links can be used for WebShell monitoring.

How to quickly detect whether Web Server has been controlled by WebShell is very important to website security.

In different usage scenarios and operating environments, the functions of WebShell are not the same.

There are many ways to detect Webshell, including HTTP traffic, Web access logs, file characteristics, etc.

The website is implanted with a webshell, which means that the website has high-risk vulnerabilities that can be exploited.
