Enhancing Information Security with Virtualization
Information security, risk management, business continuity planning enhancement, alongside compliance with global regulations and security requirements in contractual relationships with customers and partners, are some of the major considerations that are prompting organizations towards looking at deployment of virtualization solutions.
Virtual machines have become essential to the productivity of computation, providing features such as enhanced security, integrity, and convenience, along with minimal overhead costs and improved ROI.
Pertinent Pointers to Address IT Security
IT personnel need to take cognizance of a few critical issues in their efforts towards enhancing the information security in their organizations and minimizing cyber threats and cyber attacks.
- Management and monitoring of network access
- Processes adopted for network and application upgrade
- Protection being used for third party services
- Effectiveness of the existing security system in blocking hackers
- Compliance of the system with government mandates
Designing Security with Virtualization
While it is an unrealistic proposition to try and eliminate risk in its entirety, organizations can look at adopting a proper strategy that will enable them to manage risk and also meet their privacy, data protection and information security requirements. Virtualization is an enabling technology for this strategy that ensures maximum control and protection of enterprise infrastructure and data, in addition to enabling the right level of user access.
A few of the major advantages provided by a well-defined virtualization solution over those from traditional security models include resource centralization, policy-based access control, access from any device and inbuilt data compliance.
A majority of today’s cloud solutions are built on virtualization technology. Virtualization enables increased IT agility, flexibility, and scalability in addition to cost savings.
The Key Drivers
There are several reasons that justify the need to utilize virtualization for strengthening information security.
- Increased support for mobility and flexibility: Organizations are increasingly encouraging flex-work as an enterprise strategy for increasing productivity, achieving uninterrupted business operations and reducing travel, labor and real estate costs. Virtualization ensures that mobility and flex-work initiatives are simplified while making them more secure, less expensive and faster to implement.
- Privacy, prevention of data loss, and protection of intellectual property: Virtualization helps organizations secure and manage data effectively at a single location than in multiple locations within and outside the organization, by centralizing resources in the data center.
- Global compliance: Through a centralized, granular policy control, virtualization enables organizations to develop the correct information security strategy and set of policies suiting their business needs, industry and risk profile.
- Increased value of security investments: Virtualization simplifies and accelerates endpoint security by centralizing maintenance, enabling IT personnel in organizations to focus on protection of data in the data center and respond faster to any new security requirements.
- Support for business expansion: Virtualization enables the extension of an organization’s security model to cover newer locations, groups and personnel in a cost-effective manner. Additionally, virtualization enables the IT teams to provide instant access to virtual desktops bypassing the requirement for network integration.
Virtualization ensures that desktops, data and apps are centralized, secured and delivered on demand using the data center. In addition, the access control policies coupled with the centralized data management, help in preventing data loss, safeguarding business assets and ensuring privacy.
By adopting virtualization as one of the central elements of their approach to security, organizations will be able to not just effectively manage information security risks, but also derive the optimal flexibility essential for business growth.
