The increasing importance of mobile workers in today’s businesses has been acknowledged. The mobile worker population is split into three main segments, home-based mobile workers, office-based mobile workers and non-office-based mobile workers.

Organisations should develop a proactive policy and strategy that embraces new ideas and methods to create a secure mobile workplace. “Secure mobility” is typically defined as the ability to provide employees and customers with secure “anytime, anywhere, any device” access to the corporate network.

One typical security problem that remote users may encounter is the transfer of viruses or other malware via memory cards or sync connections from infected mobile devices to laptops. Then, when infected laptops plug into a corporate network, there is the potential of further infection of internal corporate resources, possibly causing substantial damage to valuable and sensitive information. However, this is not the only security problem affecting mobile devices. The loss of data privacy that can result from a misplaced, stolen, or improperly used phone can also severely compromise corporate information.

Educate employees to use only devices that are provided by company. There are technologies to prevent unauthorised access to the network. For example, Network Admission Control (NAC) enforces policy for remote devices connecting to the corporate network, and Wireless detection devices Install wireless detection technology on your wireless networks to monitor unauthorised wireless users and the deployment of rogue access points.

There are technologies to prevent compromise of the endpoint: Client Security Software’s, Host-based Intrusion Detection/Prevention Software (IDS/IPS), and Anti-Spywares. There are technologies to prevent information loss or data loss or exposure to information: Data Encryption, and Information/Data Leak Prevention (ILP / DLP) software’s. Monitor compliance with your organisation’s mobile policy

Benefits of Mobile workers:-
1. Improved employee productivity.
2. Eliminating traditional work boundaries and creating a more flexible workspace.
3. Improved client interactions.

There are two forms of network virtualization, external and internal. External virtualization generally combines multiple networks — or parts of networks — into a single virtual entity. Internal virtualization provides system-wide sharing and other network functionality to the software containers, which act as hosting environments for the software components of the network, on a single physical system. The external variety is the most commonly used method to create virtual networks. Vendors that distribute these virtualization tools generally offer either one form or another
