o hack and gather passcodes from conference service providers to use for their personal benefit. The network roadmap addresses such issues and helps secure the product in the following ways: Run a security scan on the product to detect security vulnerabilities. Requirements for updating different vulnerabilities could be prioritized and made part of the roadmap. Find security glitches that affect parts of the product and incorporate planned security patches as part of the roadmap. This would require enough planning and testing to ensure that functionality and features are not impacted. Actively monitor new security threats and information bulletins regarding these and proactively protect and update the product's technology to ensure that the security threats are handled. Ensure network redundancy options are enabled to be able to route calls and functionality through alternate network nodes when some nodes have been compromised or rendered ineffective by attacks. An example would be the concept of an MME pool that helps provide such redundancy along with load-balancing capabilities. Ensure new features do not introduce additional security vulnerabilities. CHAPTER 4 NETWORK ROADMAPS Engage a security consultancy to do a security audit of the product and the network, which could mean: Intensive testing of the system for attacks by simulating these Probing the system for vulnerabilities Strengthening security of the system by reviewing password policies Ensuring all protocols and communications are secure Also ensuring all paper systems surrounding the product are secure The resulting input would be features that could then make their way into the network roadmap to ensure a secure product that can withstand all threats. Summary We began this chapter by examining the need for technology roadmaps and how they can be formulated. We looked at different perspectives that such roadmaps can provide, and the level of detail that can be established in them. We then looked at Network Roadmaps and demonstrated how network opt
