Defense in Depth: The Way to Stronger Security.

Layered protection through security design, policies and processes

As regulatory compliance and audits increase in frequency and complexity, organizations are motivated to address security now rather than later. Many an IT professional has begun to fret about the latest network or application incident, whether the last security fix broke something, and which assets have been left unattended in the complex world of today’s mobile environments.

The solution to these concerns is Defense in Depth: multiple layers of protection that reduce a network’s exposure if one layer is compromised. A single layer, no matter how robust, cannot be exclusively relied upon within a sound system. By coordinating multiple security countermeasures, Defense in Depth adds layers of protection against threats which have already been protected against.

But these double checks don’t just create a firmer security foundation for your system. Defense in Depth also minimizes adverse impacts in case of attack, by making it more difficult for hackers to exploit vulnerabilities within the system.

Our recommendation: begin by analyzing your organization’s environment and creating the necessary risk management solution—layered protection through security design, policies and processes, and defining roles and responsibilities. We also recommend that you include off-site and mobile device management through your data centers, as well as critical assets all the way to the edge of the network, installing intrusion prevention solutions where needed at the network egress points, in a well thought-out risk management model.

In addition to improved security, your organization will also benefit from: better network protection, faster identification and resolution of security problems, enhanced visibility, reduced risk, increased compliance, and efficiency—ultimately, a successfully protected and managed business.
