Virtualization has evolved rapidly to become a necessary part of cloud security strategies. A recent Gartner study states that over 30% organizations across the globe will implement virtualization tools for their data requirements by 2020-end. Virtual machine infrastructures have been the most adopted powerful technology in recent years, despite the related risks such as man-in-the-middle and DoS attacks.
Endpoint security remains an oxymoron concept while being the holy grail for organizations worldwide. As cybercriminals grow more and more sophisticated, security tools are evolving in tandem, with virtualization technology enabling operating system isolation and enhancing safety. This has made virtualization the best approach to cloud security, helping organizations keep sensitive information safe.
How Virtualization Drives Cloud Security
Organizations are leveraging virtual machines in several ways for enhancing their cloud security, which include operating system virtualization, application virtualization, and virtual desktop infrastructure. While the last two address a small part of the vulnerability landscape, operating system virtualization removes cloud security issues inherent in application and VDI virtualization software.
The operating system virtualization enables organizations to protect critical information against every attack vector. Also, in contrast to other approaches it ensures them to realize the performance expected and sought in professionals. With this, the end-users of an application can install, work, and access resources as and when required, without security barriers or worrying about compromising sensitive data.
Key Cloud Security Benefits with Virtualization
By adopting virtualization in their cloud environment, organizations can realize the following security benefits.
- Organizations have the flexibility to share systems without essentially having to share critical information or data across the systems.
- They can prevent loss or damage to critical data, in cases where the system is compromised owing to malicious activities.
- They have the ability to reduce the risk of multiple attacks in case of an exposure by methodically isolating applications and virtual machines.
- It improves the physical security of organizations by reducing hardware requirements, thereby leading to fewer data centers.
- A higher level of access control is offered to system and network administrators, which separates responsibilities and improves the system’s efficiency.
A key consideration that organizations must take into account is that their system must be appropriately set up or configured to leverage virtualization for cloud security effectively. Modern organizations must safeguard their virtual environments against the growing plethora of threats.
Some of the key considerations in protecting a virtual environment include keeping software updated, following configuration best practices, and utilizing AV software. While some risk of threat remains even with some defenses, it is essential for organizations to implement security tools to track changes and maintain throughput security.
The Way Ahead
Virtualizations is a viable solution for organizations that focus on strengthening their cloud security. To ensure a robust security posture, multi-layered protection must be put in place and followed thoroughly. Organizations need to strategize and have better preparedness and understanding of handling the security issues in virtual infrastructure and its components. Virtualization must be a top priority, not an afterthought, for organizations that look to strengthen their cloud security.
