Key Considerations for Virtual Machine Security in Cloud Computing

0

Virtualization is quite popular in cloud computing. There is a seamless transition from physical devices that are replaced with servers that are run through hypervisors in cloud infrastructures. In addition to a reduction in spending, the move to virtual machines (VMs) provides greater flexibility and scalability. However, security in cloud computing is still a major concern among organizations. This article will highlight key considerations for virtual machine security in cloud computing.

Enforce strict access controls

One of the most basic measures one needs to undertake to secure VMs is to put strict access controls in place. A comprehensive access control policy should be implemented using the principle of least privilege. To achieve this, restrict access to sensitive information to those who genuinely need it. A good access policy should account for how users will interact with VMs.

Regular patch maintenance

Regular patch maintenance is necessary to secure VMs. Running VMs with outdated patches creates a window of opportunity for hackers to exploit vulnerabilities in the patch history. Regular maintenance can significantly reduce potential threats to the system.

User behavior analysis

Every user who interacts with the VMs can either provide an extra layer of security or become a liability. Any authorized user who is granted access to the VM should be trained and fully aware of their role in keeping the system secure. Similarly, log everything that authorized users are doing on the system to detect misuse or potential threats.

Encrypt sensitive information

Encryption can be used to safeguard information that organizations wish to keep secure. Successful organizations should never allow any sensitive information to be transmitted over the internet without encryption. VMs can store customer data or personal data that are invaluable to organizations. Encryption can provide an extra layer of protection if there was ever a data breach.

Ensure data backup

It is essential to ensure that data stored in VMs is backed up to protect against data loss. In addition, ensure that data backups are also stored off-site. This means that even if a VM is affected by any form of data loss, sensitive data can still be retrieved from backups.

Segregation of network

Ideally, organizations should not run VMs in a single network environment. This is because if one VM is compromised, it can affect other VMs in the same environment. Instead, create multiple segregated network environments to limit the scope of any possible attacks.

In conclusion, organizations must ensure that the cloud provider they use has efficient systems in place to guarantee the security of the VM infrastructure. In addition, security policies should continuously evolve and be reviewed to account for new and emerging security threats. With these key considerations in place, VMs in cloud computing should be secure from external and internal threats, ensuring both customer satisfaction and trust.
