What are the effective protective measures for enterprise cloud?

A large amount of data accumulated by enterprises in the cloud has become an important target of cyber attacks. The National Internet Emergency Center tracked and monitored the domestic cloud network security incidents of 20 domestic mainstream cloud service providers. It shows that from 20 18 1 1 to 12, 44 1 cloud service providers' web pages have been maliciously tampered with, accounting for 58.3% of the total number of tampered web pages in China.

On the one hand, more and more services and data are carried on the cloud, and the protection risks are gradually exposed; On the other hand, compared with traditional enterprises, cloud users pay more attention to the protection of network security.

So, what network security protection measures can enterprises take on their own initiative?

Security protection strategy

1. firewall -WAF (network application firewall)

Now almost all applications are provided by the Web. Compared with traditional firewall equipment, Web application firewall provides the protection ability of application layer and is more professional. Web application firewall is used to monitor and prevent common attacks on websites. Support the discovery of network attacks, such as SQL injection and XSS cross-site. It can reduce the risk of downtime, tampering and data theft for users, and hide the source station to prevent direct attacks on the source station.

2. Encryption and authentication technology

In order to prevent the line from being stolen and ensure the integrity of the network session, all data, files, passwords and control information that need to be transmitted through the network are encrypted. In order to verify the identity of the data receiver at the client and server, it is necessary to provide a valid security password and information card and verify the information before obtaining data information.

3. Network security defense measures

The frequent occurrence of security accidents such as network attacks and network intrusions is mostly due to the insufficient deployment of defense tools. There are many protections against DDoS attacks that websites often encounter, and the most effective ones are as follows: high protection IP, high protection server, and high protection CDN acceleration. Blue Team Cloud provides systematic DDoS network defense products and services, reduces the cost of DDOS defense, and provides users with cost-effective DDOS defense services.

Step 4 protect customers

(1) In order to reduce viruses and prevent them from spreading in the enterprise network, virus prevention, virus detection and anti-virus technology are mainly adopted. The client must install antivirus and Trojan horse killing software to kill viruses and Trojans in time.

(2) Download and install patches in time, fix system and software vulnerabilities, and effectively reduce potential security vulnerabilities.

(3) Do a good job in the use of mobile media protection, must be disinfected before use.

5. Data backup and recovery

Data backup is the basis of disaster tolerance, and it has become an important means for enterprises to recover data when catastrophic events occur in the system. Data backup and recovery is the process of copying all or part of data sets from the hard disk or array of the application host to other storage media to prevent the system from losing data due to operational errors and system failures. Establishing and strictly implementing a complete data backup scheme can ensure that the system and data can be recovered quickly and safely when they are damaged.
