Cloud security trick: Ten tips for protecting virtual systems

Now, more and more enterprises are deploying desktop and server virtualization technology, all kinds of racks, computing, storage, network and other resources are integrated into the resource pool. And the future trend is also towards the "smaller performance is stronger, less energy consumption, simple and easy to use" development.

However, as enterprises move more from the physical platform to virtualization, cloud service creation and deployment is becoming more and more convenient, security has become a top priority issue. So, in the cloud environment, how to effectively protect the virtual system? Below, we provide you with the following ten tips:

I. Traditional security controls are still available

In the process of transitioning to a virtual environment, we still cannot forget some traditional security methods. such as virus protection tools, firewalls, intrusion detection, and so on, they are still on the server and virtual host on the stage. It is worth mentioning that these security tools are likely to cause unexpected interruption of service during a major security upgrade.

Ii. Protection of Hypervisor

Access portals are provided at the top level of the virtual environment. Virtual security controls can help prevent unauthorized changes and intervention in hypervisor.

Iii. creating a virtual security policy

Usually we have a security policy in the physical environment, but we also need this security policy in a virtual environment. Many of them can be used, but there are many other aspects that are different from the security policies in the physical environment.

Iv. Sectoral collaboration

Virtualization generally involves the entire enterprise sector, so it is also prone to security surprises. It is necessary to ensure that communication is open to all departments within the company in the presence of conflict and security surprises.

V. Create VIRTUAL endpoint Security

Traditional firewall and intrusion prevention monitoring system can play many roles in virtual environment and porting to cloud architecture. Virtual firewalls and IPs need to be deployed at some key architectural points. Similarly, monitoring and tracking enterprise consolidation security information and event management systems cannot be overlooked.

Vi. Batch Management

The cloud has many of the same or similar problems, and the virtual environment needs to be managed in batches based on the critical value of the system and data.

Vii. the Management privilege

role-based access control can be very promising in virtual environment. Administrative access permission settings can be continued according to the precedence rules.

Viii. deployment of virtual debate and defense-in-depth

Problems can occur in each system, virtual environment. Deploy a debate in a virtual system to log in and analyze, to add more visibility to the depth of defense for each virtualized device.

Ix. devote more effort to training

Virtual security training differs from security training in the physical world. Almost all traditional tools are deployed and managed differently in a virtual environment. Prepare budget and make plans for team training.

Ten, pay attention to the problem of compliance

Compared to the physical environment, the virtual environment will be a more skeptical attitude to look at. Therefore, it is necessary to provide a more in-depth security detection and management of virtual systems, so as to constantly close to safety compliance requirements.
