How to enhance the security protection of CVM? In view of this problem, today, the editor summarizes this article on the security protection of CVM, which can be used for reference by interested friends. I hope it will be helpful to you.

The methods to enhance the security of server rental are basically to isolate resources, encrypt user data, strengthen the security of the server rental system, invest in some security testing and protection equipment independently developed or purchased from third parties, and at the same time invest in a large number of security teams and operation and maintenance teams to provide 24-hour service. In addition to these, there are some security issues to enhance the security of CVM:

1. Basic security

First of all, the cluster is distributed and deployed in multiple data centers, and there are strict rules and mechanisms for the assets, equipment, materials and consumables of the data center. The network is basically located in the core backbone area, and the property security is patrolled in segments for 7 × 24 hours. And carry out 7 × 24-hour centralized video surveillance on all infrastructure. It ensures the strong guarantee of physical machine and operating environment.

2. Network security

In the aspect of network security, multiple defenses are adopted, and the traffic in the cluster is strictly controlled through firewalls, ACL and other security measures to protect the servers in the cluster from internal and external network attacks. All physical machines and server leases are strictly separated by VLAN, and the same tenant falls into a VLAN, while different tenants do two-tier isolation, which can effectively prevent security threats such as arp spoofing and port scanning caused by server leasing. The access control list is set in the form of whitelist, so that only trusted hosts can access the hosts in the cluster; the investment of self-developed top protection products, such as website bodyguard, network full traffic analysis and other equipment can effectively prevent common network attacks such as syn   flood and cc.

Regular security scanning, timely detection of security vulnerabilities, rapid repair or protection of vulnerabilities.

3. Account and system security

Organize a professional security team, combined with years of practical security experience, the server leased image has carried out a series of security reinforcement strategies. This includes account management and security authentication, such as prohibiting root account login (no restrictions are imposed by other cloud service providers), disabling unused ports and hiding historical operation records; complex password settings include mandatory password length and complexity settings that must contain uppercase and lowercase letters, effectively reducing the risk of user accounts being violently cracked.

The physical machine system chooses the stable version of the operating system in release, installs the software package in a custom way, deploys the basic system in a way that minimizes installation, and updates patches and software versions in time to plug known vulnerabilities. Two-factor authentication is supported. After purchasing and renting a server, it is bound to the tenant's mobile phone. You need to enter a check code to reset the password, reinstall the system, and delete the system to continue the operation. The addition of two-factor authentication is another effective guarantee for the security of the account.

4. Safe operation and maintenance

Centralized group and role management system to define and control permissions,   operation and maintenance engineers have a unique identity; through encrypted channel management, with identity authentication and authentication; all login and operation processes are audited in real time. Establish an internal traffic convergence point to monitor the dynamics and traffic of the whole network.

Real-time CPU, bandwidth and disk monitoring of physical machines and servers are leased, and anomalies are immediately alerted by SMS and email.   real-time resource monitoring is an effective way to show the use of resources, and it is also one of the effective ways to automate operation and maintenance.

5. Security audit

All the physical machines in the cluster enable shell   log to redirect logs to independent log servers; provide a unified log security audit system for the entire security infrastructure, including virtual environment;   enables audit for account management, login events, system events, policy changes, account login events success and failure.

Server renters should strive to provide high-performance, reliable and secure cloud services for enterprises and individual users, minimize the IT infrastructure technology and cost threshold needed for enterprise development, and provide maximum convenience and professional security service system guarantee for enterprises to migrate to the cloud.

This is the end of the way to enhance the security protection of CVM. I hope the above content can be helpful to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
