CHAPTER 1 Networking and Security: Trends and Challenges 11 These materials are © 2020 John Wiley & Sons, Inc. Any dissemination, distribution, or unauthorized use is strictly prohibited. Too many siloed security tools and integration challenges Security teams are frequently inundated by mountains of data from standalone, point security products that don't integrate with other products and require different knowledge levels and skill sets to operate and maintain. The Enterprise Strategy Group reports that 31 percent of organizations use over 50 disparate tools, and Cisco research indicates that the majority of them find it challenging to orchestrate alerts from these different tools. This lack of integration and interoperability makes it difficult, if not impossible, for security analysts to monitor and correlate security and threat information in real-time. These challenges have grown exponentially as connected branch and remote offices have proliferated. Each location typically requires a router and firewall at minimum. In remote and branch locations, these are often purchased as commodity components that provide limited functionality and remote management capa- bilities. When switching to DIA at remote locations, there is a need to deliver the right level of security to users — web security, firewalls, data loss prevention, and so on. However, it's impracti- cal to buy a separate stack of security appliances for each location. Even if some of these components in branch locations do include security tools, there are usually no IT personnel in these locations to maintain them. Over time, the hardware can't cope with the ever-increasing traffic loads, so the security tools will need to be displaced from these appliances to the cloud where they can be applied and managed centrally. There's light at the end of the tunnel. According to the Cisco CISO benchmark study, 93 percent of CISOs agree that moving security to the cloud has increased efficiency, allowing security teams to focus on other areas. Security talent shortage and increasing personnel costs The worldwide shortage of security professionals and the high ongoing investment necessary to train and retain qualified secu- rity staff is a very real problem for organizations everywhere. According to Cybersecurity Ventures, 3.5 million cybersecurity jobs worldwide will not be filled by 2021. The Enterprise Strategy
