Network virtualization is a way of combining different physical networks to make them function collectively as a single virtual network or vice versa. At times, the process may also include virtualization of storage solution, which facilitates using all storage devices as a single resource. Network virtualization can serve multiple purposes, depending upon the specific requirements of an organization. This may be aimed at either improving the efficiency of the in-house IT systems or lowering investment in additional hardware components.

Given below are some of the benefits offered by network virtualization:

Centralizing Confidential Data

Due to the increasing data breaches and other online attacks, many business owners are considering storing their data on a centralized location. With this, a hacked computer system, lost/stolen device or negligence on the part of an employee would not pose a major risk to the security of sensitive information. When IT administrators store the data on a centralized server, it mitigates the risk of theft, malware infections and unauthorized access to the company’s intellectual property.

Setting Up A Sandbox

Sandboxing involves demarcating and isolating all the applications that may pose a potential threat to the internal network of the company. Network virtualization proves to be a great help in this regard. When a sandbox is created for web browsing, it prevents all the online attacks from affecting the host server and applications that are operating out of the virtual environment.

Facilitating Secure Network Access

With the increase in ‘bring your own device’ (BYOD) and work from home culture, a lot of employees access the corporate network from their personal devices as well as from multiple locations. When virtualization is used, the employees do not have to deal with the management and security aspects of the network. All these can be handled at the back-end by trained IT staff at the office.

Security Risks Of Network Virtualization

• When virtualization is added to the IT infrastructure, it can make it more difficult to monitor and detect security issues, such as advanced persistent threats (APTs).
• Network virtualization creates a dynamic environment which, at times, may lead to virtual sprawl. This means that the administrator may not be able to keep a track of the online activities and security vulnerabilities that can be exploited.
• To eliminate these risks, it is important to improve the security of the host machine. Virtual systems that are not performing important business operations or remain unused should be removed from the network. Lastly, strict access control policies must be implemented to secure the virtual network.

Wearable devices have provided a tremendous opportunity for business organizations to keep the employees connected to work and improve their efficiency. The use of smart glasses, watches, headgear etc. facilitate better data collection and better customer service abilities. However, just like every other technology, security risks are bound to come along. The extensive functionality served by these devices can sometimes magnify the threat surface, thereby introducing many new ways in which data can be compromised.

Here are some of the common security risks posed by wearable devices:

Lack Of Data Encryption

Wearable devices do not use encryption protocols to store the information securely. There is no sophisticated PIN or password required to gain access to the data. They also do not have any biometric or other authentication methods to validate the identity of the users. As a result, there is a serious risk of data theft if the device is lost or stolen.

Difficulty In Patch Management

Most wearable devices function on a completely different operating system and run several third party applications. Hence, frequent software updates and patches are not readily available for these devices. This makes them an easy target for the hackers to carry out malicious attacks in order to exploit the vulnerabilities and intercept information shared through the wireless networks.

Insecure Wireless Connectivity

In order to function efficiently, wearable devices need to be connected to your mobile device through Wi-Fi, Bluetooth or Near Field Communication (NFC) technologies. However, when you keep the connectivity options enabled, you may inadvertently allow hackers to download malware or malicious programs to your device. They may also launch a brute force attack to breach the password of your device’s wireless network.

Recording Sensitive Information Through Photos, Videos and Audio

Wearable devices come along with a very discreet ability to record the important information about your company in the form of audio, video and images. Smartwatches and smart glasses can easily be used to capture and transmit confidential data to the hackers, without leaving any trace. This type of data breach cannot be prevented by anti-malware, anti-spyware and any other form of security software.
