Question

Which of the following can be used as countermeasures against VM escape?

1) Network segmentation
2) Regular patching
3) Strong access controls
4) Encryption
5) Intrusion detection system

Answer 1

Effective countermeasures against VM escape include network segmentation, regular patching, strong access controls, and implementing an intrusion detection system. These methods help prevent the breach and contain any potential damage.

Step-by-step explanation:

The question pertains to countermeasures against VM escape, which is a security breach that allows an attacker to access the host machine from within a virtual machine. The following countermeasures can be effective:

1. Network segmentation: Isolating different parts of the network can contain breaches and prevent attackers who have compromised one virtual machine from easily accessing others or the host.
2. Regular patching: Updating systems, applications, and virtualization software with the latest patches can fix known vulnerabilities that might be exploited for a VM escape.
3. Strong access controls: Implementing strict access policies can help in preventing unauthorized access to virtual machines.
4. Encryption: While encryption protects data at rest and in transit, it does not necessarily prevent VM escape, but it does protect sensitive data if a breach occurs.
5. Intrusion detection system (IDS): An IDS can monitor the network and systems for suspicious activities that might indicate a VM escape attempt.

Overall, a combination of these countermeasures, where applicable, enhances the security of a virtualized environment.
