    • Consumer Technology in the Workplace: Managing Security Risks and Maximizing Employee Productivity Point of View As employees become more mobile and use more consumer To protect the organization from these new threats, an IT technologies in the workplace, corporate systems and department needs to create an extended security model that information are increasingly at risk from security breaches. better secures the most exposed and weakest layers in the All organizations know that they should strengthen IT security, environment—the endpoints and the network infrastructure— but smart IT departments approach the task in a way that and that includes employee education and policies that direct improves, rather than stifles, employee productivity. user behavior. However, this needs to be done in a way that still gives employees access to tools and capabilities they Traditional security models in which corporate information need to do their jobs more efficiently and effectively. is protected by secure network perimeters only around an organization’s office environment are becoming obsolete. Enhancing Endpoint Security This is due to more mobile employees accessing corporate For today’s employees, the nine-to-five workday is a thing systems from outside the office and a proliferation in of the past and the workplace can be just about anywhere. the number of device types and online tools, including Depending on where they are and what they are doing, smartphones, netbooks, Web 2.0 applications and social employees may choose to work on different devices, such as networking sites, that increase the number of corporate a laptop in the office, a smartphone while checking emails network entry points. These trends will only gain momentum on the weekend, and a netbook while traveling. While out of as younger-generation ‘digital natives’ enter the workforce the office they may be connecting to the network via a phone and more organizations allow employees and contractors to connection or even an unsecured wireless link, which renders bring personally-owned devices into the workplace. the traditional security perimeter around a single office The productivity benefits gained from the increased employee environment obsolete. To support the anytime, anywhere mobility, flexibility and job satisfaction that result from the workplace, organizations need a new security perimeter that use of these new IT tools are considerable. However, as IT expands beyond four walls and flexes to cover all possible departments come under pressure to effectively manage device types and connections an employee chooses to use and protect employee behaviors enabled by new tools, threats at any given time. to the corporate network are becoming more sophisticated, When employees connect endpoints (such as PCs, netbooks, targeted and insidious. Viruses, malware, spyware and PDAs or smartphones) to the network at the office, they are phishing attacks are increasingly tailored to exploit specific protected by an enterprise-class security infrastructure that security holes created by new device types and online tools. includes firewalls, IPS, proxy servers and more. However, Employee downtime and the time and resources required to recover from such attacks have a real impact on employee when employees take devices out of the office, they become and business productivity. an exploitable leak in the perimeter.
    • An employee using a device outside of the office can specifies which external devices (such as USB drives, MP3 unintentionally let his or her guard down, catch a silent virus, players, Bluetooth devices and DVDs) can be used on a PC and then carry the virus inside the organizational perimeter and what data can and cannot be copied onto these devices, upon return to the office. An infected endpoint can enable even when the user is not connected to the corporate network. a person with malicious intent to gain ‘authorized’ access Windows 7 also includes technology that prevents applications to a device or corporate network by collecting and re-using from being loaded onto a device unless they are on a defined an authorized account and password, or take advantage list, and a function that acts as a ‘kill switch’ to remotely of the user’s access when he or she is logged in. Viruses disable a device so that the data on it cannot be accessed. and malware are not the only threats. An opportunity for These built-in solutions can be powerful tools for securing unauthorised access to the corporate network or sensitive devices, but it is up to the IT department to enable them as data can happen as simply as an unsecured laptop or USB an integrated part of a security solution. device being misplaced or stolen. This is why a critical element Enhanced endpoint security provides a strong layer of of an extended security model is enhanced endpoint security protection against threats and gives organizations more that includes stronger technology solutions to protect against confidence in allowing employees to be more mobile and infection and unauthorized access. use a wider range of devices and applications that enhance Most organizations have endpoint security in place through productivity. However, some threats will still permeate the the use of host-based firewalls, anti-virus and anti-malware endpoint layer so an extended security model must also software, and identity management solutions. However, IT include greater protection for another vulnerable layer: the departments are not going to be able prevent every breach, network infrastructure. so the challenge is to find the infection faster and eliminate it at the endpoint before damage occurs. Despite long-term Controlling Network Access use, virus and malware controls on endpoints are not entirely The necessary reality these days is that an endpoint should effective. This is because most existing controls are based be treated as a threat unless proven otherwise. Network on blacklists that block access to known threats but are less Access Control (NAC) requires devices to prove they are effective against unknown threats, which can sit hidden safe to connect to the network (pre-admission), as well as within a device or the network for some time until activated. controls where the endpoints are authorized to go and what Whitelist or behavioral-based threat protection solutions they are authorized to do. When an endpoint attempts to deployed to endpoints help identify, quarantine and eliminate access a network, an established security policy is invoked unknown risks more quickly, so they should be part of an to ensure the endpoint meets all the required criteria in enhanced security model. the policy. For instance, the policy might require that the To further protect against access threats, other important endpoint has an appropriate firewall and anti-virus protection aspects of an enhanced security model are robust access installed before the endpoint will be allowed to communicate management and identity authentication solutions on on the network.

NAC solutions allow network administrators Not only are there more sophisticated solutions for endpoint to define policies for endpoints without the need to have full security being brought to market every day by security vendors, (or any) control of those endpoints. NAC solutions provide these solutions are increasingly being installed onto devices a layer of protection against improperly used, infected or by OEMs and included in the latest versions of operating rogue endpoints attempting to connect to internal network systems.

For this reason it is also important over security. However, it is becoming more common for for organizations to increase protection for data at rest in organizations to allow employees or contractors to connect storage devices as well as data in motion on the network. their personally-owned devices to corporate networks. For highly-sensitive data, this may mean implementing Employee-owned equipment is a potential carrier of infections encryption technology as well as improving NAC. across the security perimeter.

The second part requires additional effort to truly measure the levels of employee productivity, the bottom-line value, Balancing Security With Productivity and the benefits versus the cost. The most immediate place For every organization, productivity may mean something to start is by surveying workers and managers regarding their slightly different, such as employees’ ability give higher quality needs, if and how they use the IT tools they are given, and service to customers or citizens, meet critical deadlines, the benefits they see from greater mobility and the use of drive new innovations, or bring products or services to market consumer IT tools. Common methodologies, such as Six Sigma faster.

By within the organization. From evaluating these two parts, the tightening security controls too much and denying employees productivity benefits can be weighed against the increased the right tools, access and data, productivity is stifled. security costs to enable employees to be more mobile and use The key question presented to IT departments today is: how a greater selection of consumer technologies in the workplace. can they measure the productivity benefits gained from mobility With the many different types of IT devices available, the and consumer technology against the risks and costs of growing popularity of social networking sites and Web 2.0 an extended security model?
