In conclusion, to provide corporate level security for laptops operating outside the safe office environment, CSOs should consider layered security architecture on a hardware appliance.

A dedicated appliance can hold all of the best of breed security softwares, and is able to re-introduce the two lines of defense enjoyed by office based PCs.

By introducing a security gateway, should security be breached, the damage stops at the gateway. Businesses around the world are being bombarded with sophisticated threats against their data and communications networks every day.

1. As enterprises invest heavily in fortifying their IT infrastructures and enforcing comprehensive and constantly upgraded security policies against malicious code attacks, another home-grown threat - the mobile workforce - is opening the floodgates to compromised enterprise data and corporate network contamination.
2. Though mobile working offers gains in commercial and operational value, enterprise security policies often stifle the effectiveness and productivity of mobile workforce devices. Here we examine why best of breed softwares, in isolation, are not able to provide the mobile workforce and their laptops with the same high level security afforded to office based workers.

Two lines of defence in a protected corporate environment. Currently organisations anticipate, detect, and prevent threats from laptops attacks via a layered approach. This is coupled with centralized, uncompromising IT policy which overrides an individual’s control over his/her own laptop.

As IT departments prioritise corporate IT governance, their primary method of effectively enforcing organizational security policies is by controlling all networking components.

When connecting to the Internet from within the corporate network, laptop users are protected by two lines of defence:

A comprehensive set of IT security appliances running secured and hardened Operating Systems, and security software including firewalls, Intrusion Prevention/Detection System, antivirus, antispyware, antispam, and content filtering, all of which are completely controlled by the respective corporate IT organization.
