How to reduce the security threat of data in the cloud? Security is the key reason why many companies are unwilling to "get involved in cloud hosting". Because cloud computing technology will lead to many changes in the actual operation mode, it is normal for companies to choose the cloud carefully. After data information is transferred from the server intranet to the cloud, it seems that its harm is more serious, and data information browsing is also vertical. Naturally, enterprises and information technology departments are trying to reduce the security threat of data information between clouds.

1. Know where the data information is. If you don't know where the data is, how can you ensure its security? Naturally, server firewalls, intrusion prevention systems and defense forces can avoid most intruders, and database encryption can also make data information more secure. But when you stop the service project or the cloud business goes bankrupt, can you know where the data information is? You can lean on a device and say that your data information is on this computer, which is very beneficial to ensure the security factor of data information between clouds. Dedicated hardware configuration is an important factor for cloud computing technology to meet the most stringent security rules.

2. Frequently back up data information. One of the most easily overlooked aspects of cloud computing technology is that it is also a very simple way to improve the operation of data information: no matter what happens, you have the security of data information to back up data. Detailed data backup with data information is not only conducive to ensuring network information security, but also reassuring.

3. Ensure that the network server or big data center attaches great importance to security risks. By knowing which server network or big data center the data information is located in, the company can detect and investigate all feasible security methods it has deployed. Companies can see if their security systems comply with authoritative security verification. If the network server or big data center can display service projects in a manageable way, it can also improve many benefits and expertise for the company, thus making application software, data information, business processes, etc. more coordinated. For example, manageable server firewalls and manageable intrusion prevention systems are usually provided by reputable big data centers or cloud distributors. Such manageable service items can enhance the security measures of manageable network servers.

4. Get reference suggestions from other customers. When the company has questions, why not consult other customers of cloud distributors, especially those with strict security measures? For example, why not consult with an auto insurance company? Although reference to others' suggestions cannot guarantee anything, it is very useful if other companies using the same distributor have similar safety plans with your company. Please be sure to contact such customers as soon as possible to find out what the enterprise has done to ECS and what security precautions it has taken.

5. It is unnecessary to assume what is safe for continuous detection. The only way to detect whether data information between clouds is secure. For enterprises with high aspect ratio confidential data, it is very important to hire a skilled social morality hacker to check their own security. Vulnerability scanning systems and assessments are particularly important both inside and outside the cloud. Note: If you can find a way to browse data without authorization, others can also.

6. Data encryption of static data, application data and transmitted data information is considered to be the best way for all companies that attach great importance to security awareness, and its high cost performance ratio is attractive to companies that choose cloud computing technology. The company adopts appropriate data encryption methods to make data information more secure and get twice the result with half the effort. When data information is in the cloud, virtual disk, database query between clouds, or in Alibaba Cloud OSS, it is very easy to be exposed. During the whole data transmission process, when the data is transferred from the client's computer browser to the remote server in the cloud or the middle of the virtual machine, interception is likely to occur. A really nasty network hacker may even browse the root account of the virtual machine and query the running memory of the network server when applying data information and computing. The company should be clear about this probability and choose a solution that can deal with this risk.

7. Define security management Many policies, regulations or standards (such as PCIDSS) stipulate that data should be encrypted at several points. This means that data encryption is not a problem for others (customers, dealers, machine equipment manufacturers, etc.), But it is a problem for the company. On the issue of network information security, we don't need to rely too much on the energy of the outside world, and we must learn to "do our own work, and be comfortable with food and clothing". According to statistics, many enterprises and even their own virtual machines have been hacked. On the issue of cloud data encryption, the company must assume obligations. The key is to clarify what kind of elite team should be the security commitment of data information; What obligations should the company assume if its safety is damaged due to mistakes.

8. It is not easy to check various options of cloud data encryption and select the strongest scheme to correctly implement data encryption. The best choice is to apply the scheme that experts believe. The company should check the data encryption scheme available to the ECS. Choosing a private or cloud computing platform plays a key role in choosing a cloud data encryption scheme. The company should ensure that the strongest data encryption standards are applied and checked frequently.

9. Prepare for data encryption in advance for the worst case. In order to better prevent external network hackers from browsing enterprise data, you may have strengthened the network server, but what about internal employees? The company should make preparations in advance to solve the worst situation. For data information that has been encrypted with strong data, the company should only allow employees who need to work to browse, learn how to train such employees to browse encrypted data information, where to browse, and stipulate that they comply with security regulations. Don't forget data encryption, backup data, and snapshot updates. The purpose of data encryption is to maintain several data packets and backup data, especially the key.

10. Maintenance key The purpose of handing over the key to the security manufacturer or cloud distributor is to show the overall goal to network attacks. The company should apply the strongest data encryption key technology, such as stateful key management, to enhance the security of the key. Homomorphic key displays two keys, in which the master key of data encryption is handed over to the application software or data message

Information itself can still maintain data encryption in the whole process of application software and data information. Even if the master key of data encryption is stolen, illegal customers still cannot open data information.
