ElasticComputeService (ECS) is a computing service with flexible processing capacity, and its management mode is simpler and more efficient than physical servers. CVM helps you quickly build more stable and secure applications, reduces the difficulty of developing OPS and the overall IT cost, and enables you to focus more on core business innovation. More and more enterprises and technical teams are willing to put their business and data on the cloud, and sense of security is more likely to deal with data on the cloud. The professional network protection capability of cloud service providers can effectively resist attacks, intrusions and other means, and the risk of stealing and tampering with data is significantly reduced.

The CVM has early warning measures for security crises, strategies for correctly dealing with security incidents, and a technical team to monitor the network environment all the time. Many people realize that storing data in a cloud is more secure than renting a traditional server.

Excellent cloud service provider platform has a secure, solid infrastructure, highly secure computing, storage and network environment. In contrast, the traditional IT system has some disadvantages, such as outdated hardware, unable to update in real time, slow response to security crisis and so on, which is more likely to make malicious attacks successful, resulting in online business and core data loss.

Of course, it is incorrect to think that any cloud platform is absolutely secure. There are many cloud hosting products in the market, and the capabilities of cloud computing service providers are still different.

Established service providers have perfect security mechanism, complete professional certification, and strong ability to defend against network attacks. Put data on their cloud without having to worry about data security and network risks. Therefore, it is critical to choose a cloud service provider, with professional certification, such as Western Digital.

The adoption of CVM by enterprises is a safe security solution. When abnormal status and security risks occur, the cloud will send reminders to users to help users avoid human error. Efficient safety management enables users to standardize operation and strengthen safety protection awareness.

Security measures for CVM

Do not install redundant programs

When renting a CVM, do not install other redundant programs such as QQ, game client, video player, etc., and do not watch movies and play games on the CVM, so as to avoid occupying broadband and system resources, thus affecting the normal operation of the server. In addition, do not browse unsafe websites on the server to avoid poisoning.

You should be careful to modify the port

There are many important ports for CVM. It is recommended that you modify 3389, 21 and other important ports, so as to reduce the chance of being scanned by hackers, but you must be careful when modifying. You need to be fully familiar with the modification process before you modify it, so as to avoid that the server cannot log in or some important functions cannot be used properly due to modification errors. Friends who will not modify suggest contacting cloud computing service providers for help.

Avoid downloading large data and software

Make sure that the download speed can be set within the scope of use.

Recommendations for data security protection of CVM

Back up data regularly

The significance of data backup is that when network attacks, virus intrusions, power failures or operation errors occur, the original system can be restored completely, quickly, succinctly and reliably, and the normal operation of the system can be guaranteed within a certain range. In terms of data backup, enterprises should regularly carry out tape backup, database backup, network data backup and update, remote mirroring operations, etc., as well as multiple data backups.

Establish a disaster recovery center

In the face of regional and devastating disasters such as earthquake and fire, only data backup can not be recovered. at this time, it is necessary to have a disaster recovery center to make a remote backup of the data to ensure that the original data will not be lost or destroyed. The recovery time of data disaster recovery is relatively long, and the main methods are real-time replication, timing replication and store-and-forward replication. Of course, data backup is the most basic, there is no data backup, any disaster recovery is of no practical significance.

Raid disk array storage

To put it simply, multiple independent hard drives are combined in different ways to form a hard disk group, which provides higher storage performance and data backup technology than a single hard disk, thus greatly enhancing the security of data. The different ways to form a disk array are called raid levels, and choosing the appropriate raid level according to the actual situation can meet the user's requirements for storage system availability, performance, and capacity.

Do not operate or modify blindly

Human misoperation is an important reason for data loss of CVM. Sometimes files are accidentally deleted, or misformatted, mispartitioned, miscloned partitions, lost partition table information (MBR), etc., poor handling may paralyze the entire server.

In addition to not modifying or blindly manipulating the server, it is necessary to set reasonable permissions, such as giving "edit" rights to users responsible for daily updates. This can greatly reduce the misoperation of non-professionals and improve the data security of the server.
