The Minimalist Guide to VMWare vSphere Security
Cyber-attacks are now more sophisticated and can be carried out by organized cyber criminals or nation-sponsored groups. Virtualized environments are becoming more secure and offer many security features. However, it is important to be vigilant against cyber-attacks.
Malware used to disappear when it detected a virtualized environment. But that is no longer true. Malware makers are now realizing that IT is becoming more virtualized. Once malware has detected a virtual machine, it won’t self-destruct or encrypt it as it did in the past.
Many IT professionals worry about malware and malicious code spreading between their workloads. Virtualization allows servers to run multiple workloads simultaneously while sharing some system resources. It’s important to be aware of security vulnerabilities and threats. It’s much easier to steal virtual machines if they are reduced to one file. Migrating workloads to cloud requires different levels protection.
You will face more difficulties as you dive deeper into a virtualization effort. Cybercriminals are more attracted to virtualized assets when there is consolidation. VMware is expanding to keep up with this increase in interest. However, there isn’t one security mechanism that can completely protect your VMware workloads. It is necessary to have a multi-layered approach in the VM, vSphere and virtualization stack.

It is important to know what security features are available when learning about vSphere. VMware vSphere 6.5 includes VM Encryption and audit-quality logging. Secure Boot is also available. Encryption is performed at the ESXi kernel by applying a storage policy to VM encryption.
Secure Boot verifies every signature of the ESXi. This means that you can’t install unsigned code or VIBs. Secure Boot can be enabled on individual VMs. Audit-quality logs are also useful for auditing purposes. You can see who did what, and where.
Explaining VM encryption
VM Encryption can be managed using a storage policy-based system. You can manage the requirements for virtual disks. You can use the VM Storage Policy tab to apply policies and VM encryption to VM objects such as virtual disks. First, you need to add a key management system (KMS).
Encrypting your Virtual Machine Disk files as well as virtual machine executable (VMX), configuration files, snapshots, and VMX Swap files will result in them being encrypted and stored in files. The hypervisor manages encryption, so keys cannot be accessed by VM’s memory. This provides better protection against cyber criminals.
Learn how data is accessed
It doesn’t matter where you have your data, as long as you can access it. This necessary step is essential to identify any potential breaches. Cyber-attacks can occur anywhere there is vulnerability, whether it is on-premise or virtual. These areas can only be protected if you know where they exist.
Protect communications with the hypervisor
The hypervisor is where hackers can find account numbers and passwords. It is best to use your Secure Sockets Layer, (SSL), in all communications to protect it. To prevent cyber-theft issues, it is recommended that you install the feature yourself if it is not available by default.
Add encryption to the hypervisor
Although it may sound strange, encryption is more agnostic when performed at the hypervisor level than the VM. This allows you to manage it through storage policy. You can also use the VM Encryption Tool in vSphere. To implement the encryption infrastructure, you must first create a proof of concept (POC).
