Way to Security for Service Provider's Solution

By Enterprise Networking Mag | Tuesday, June 11, 2019

FREMONT, CA: Service providers have recognized how important security is in a network infrastructure. It is pervasive, multi-dimensional, resilient, and effective. Security and integrity of the infrastructure and devices are vital to support a thriving business that depends on networks. Defense in depth is a recommended approach to security services. It is a common practice which creates layers of security spanning across firewalls, cryptography, authentication, safety, and many more.

Protecting services delivered on network infrastructure impacts customer service level agreements. Network security always concentrates on protecting against unacceptable behaviors and keeping unwanted guests out, limiting access to critical resources, and providing adequate visibility to detect bad behaviors. A way to control the integrity of the devices has always been missing. Building and maintaining device integrity is the primary goal with a trustworthy device.

Platforms are composed of both software and hardware. The first set of instructions of a device run on the CPU which is stored in tamper-resistant equipment. Microloader, network OS, bootloader, and applications are software elements that cannot be compromised. If tampered actives go undetected, identifying it can be challenging. Reliable software mitigates the risk of compromised devices. The primary step is the integrity of the software image that is being loaded. Devices can also run for years between a reboot, and unintended binaries could be produced.

Good practices include developing software with the ability to build runtime defenses. It protects against attacks on buffer overflows and memory locations where crucial data resides. Surrounding environment needs security tools and the ability to visualize reports on it. Preparation and mature process are required to build trustworthy devices. Manufacturers having a detailed process which outlines a secure development process is the best practice when approaching product development. These guidelines include safe design, secure coding, security requirements, vulnerability testing, and static analysis.

Many companies are enhancing the security and resilience of their products and solutions. Vendors cannot guarantee security. Transparency and accountability is the key to act as a trustworthy partner to our customers and address security challenges. Trust is a multi-dimensional difficulty that spans across the hardware and software of devices operated in the network.
