Common Cloud Security Threats

Cloud deployments, whether public, private, hybrid or community, are susceptible to all the traditional cybersecurity threats and more. Let's look at the most common threats:

1. Virtual machine attacks: Active VMs are vulnerable to all traditional attacks that can affect physical servers. Once a VM is compromised, it may be able to attack other VMs running on the same physical host because the VMs share the same hardware and software resources. In addition, the compromised VM may be able to attack other VMs and hosts throughout the LAN.
2. Hypervisor attacks: Compromising the hypervisor enables a bad actor to gain control over the VMs as well as the host. One example of a hypervisor attack is hyperjacking, which involves installing a rogue hypervisor that can take complete control of a host. This may be accomplished through the use of a VM-based rootkit that attacks the original hypervisor, inserting a modified rogue hypervisor in its place.
