Cisco And Tennessee's Transportation CIO Report On Cybersecurity Trends
The digital transformation is rapidly moving the transport industry from a closed, patented and analogous ecosystem to an open, networked and always active mobility platform. It is already an excellent example of the efficiency and revenue-generating potential of the Internet of Things (IoT), and soon, as promised by legacy and upstart automakers, it will become the prototype of the future autonomous robotic, powered by artificial intelligence. .
Becoming digital, however, means a new life in the cybersecurity trenches.
The Cisco Mid-Year Cybersecurity Report 2017 includes interesting findings from a survey of 180 information security officers and security operations professionals in the transportation industry. These are the highlights, backed up by comments from Joe Kirk, CIO of the Tennessee Department of Transportation (TDOT), "moving Tennessee forward" for more than 100 years and winner of the 2017 National Road Safety Award.
The transportation industry, reports Cisco, increasingly uses the Internet as its network of choice due to several factors: the increase in maintenance costs and the complexity of existing proprietary systems; new consumer demands for security and mobility services (for example, the use of applications in their cars); and the employees of transport organizations require more and more ease of use of the connected systems.
"Our transportation network was built over many years," says Kirk, "mostly outside of IT control, which has created several challenges as we prepare to face the challenges of urbanization, population growth and connected and autonomous vehicles ". Kirk sees three key challenges related to cybersecurity: providing security to legacy devices that do not support current technology; have a workforce with the right skills to manage modern networks; integrating the separate worlds and skill sets of Information Technology (IT) and Intelligent Transport Systems (ITS) to create the optimal basis for a modern transportation system.
The transport industry is already being attacked
Cisco reports that almost half of the transport security professionals have already addressed public scrutiny due to a data breach. 35% said they see thousands of daily threat alerts, of which only 44% are investigated. Of the alerts investigated, 19% are considered legitimate threats, but only 33% of legitimate incidents are remedied.
Infractions can also have a lasting impact on the industry. 31% of security professionals said their organizations lost revenue due to last year's attacks, with an average revenue loss of 9%. In addition, 22% said they lost customers and 27% said they lost opportunities due to the attacks.
More than a third of transport security professionals said advanced persistent threats (APT) and the proliferation of BYOD and smart devices were high security risks for their organizations. In addition, 59% of security professionals said that infrastructure in the cloud and mobile devices are among the most challenging risks to defend against attacks.
As Kirk explains, human error is often the culprit. "Bad guys just have to find a hole once to get in, but we have to stop them every time to keep them out, all the technology in the world will not prevent a user from clicking on the wrong link," he says. As a result, in TDOT as in many other companies, many resources are dedicated to educating the workforce about the best cybersecurity practices. However, "Internet of Things changes that priority a bit," says Kirk. "You will not educate a device that is on the side of the road." The solution, in his opinion, is to have "an operating system for the Internet of things that does not depend on people doing the right thing".
The scarcity of cybersecurity skills negatively affects transport organizations
29% of cybersecurity professionals say that the lack of trained personnel is a major obstacle to the adoption of advanced technologies and processes. "This is particularly challenging for state governments," says Kirk. "One way to combat this is to find quality partners and cybersecurity experts to enter and educate your staff, find someone to teach your young engineers."
In fact, almost 50% of organizations outsource some or all of their security tasks to compensate for the lack of internal expertise, Cisco reports. Of the organizations that subcontract, cost efficiency (52%) and impartial vision (44%) were the main reasons for doing so.
But Kirk warns about relying too much on external experience. "We firmly believe that we must build the right level of experience and culture within TDOT before delivering part of the work to outside services," he says. "We want our partners to complement and support our team, but we do not want them to develop our strategy, we have many partners and we can not allow each of them to manage their own strategy, it is our responsibility to have the overall vision."
The value of Big Data on the edge
To meet the demands of access to information, transport security teams recognize that the data must be located at the edge of the network and be available in real time. Controlling access to data, and making sure it is available to those who need it, is a key concern for security professionals, reports Cisco. They also recognize that this problem will only increase as they eliminate closed and patented systems, and expect to have to manage a greater number of more complex threats.
"A Department of Transportation (DOT) owns an asset that no one else owns, the right of way on the side of the road," says Kirk. "A huge amount of data will flow between all the vehicles and devices that make up a modern transportation system."
This represents an unprecedented opportunity for transport departments. "We have to put the intelligence on the network to know when it is necessary that these data go back to the DOT, so that it can be used for capacity planning and when they should use our road devices to increase road safety," Church says. "It's a challenge, but we believe that the network we are building today lays the foundation for this type of work tomorrow," he adds.

Cisco Patches Multiple Vulnerabilities In WebEx Platforms
Cisco released patches for multiple vulnerabilities in its WebEx Recording Format and Advanced Re-coding Format Players to address vulnerabilities.Failures can cause the failure of an affected player and in some cases allow the execution of arbitrary code in the system if a remote attacker sends a malicious ARF or WRF file via email or URL and convinces the user to launch the file, according to One last notice from Cisco updated on November 30, 2017.
The patch has a "Critical" severity rating and addresses CVE-2017-12367, CVE-2017-12368, CVE-2017-12369, CVE-2017-12370, CVE-2017-12371 and CVE-2017-12372.
"The vulnerabilities revealed in this notice affect the Cisco WebEx ARF Player and the Cisco WebEx WRF Player," the notice said. "The following client versions of Cisco WebEx Business Suite (WBS30, WBS 31 and WBS32), Cisco WebEx Meetings and Cisco WebEx Meetings Server are affected by at least one of the vulnerabilities described in this notice." 200-150 Practice Test Dumps
However, it is possible to completely remove all WebEx software from a system using the Meeting Services Removal Tool (for Microsoft Windows users) or the Mac WebEx Meeting Application Uninstaller (for Apple Mac OS X users).

What To Expect From Cisco In 2018
As Cisco moves from hardware to software, it launches a new product line for IoT and cloud
As the leading network company designs its plans for 2018, analysts and users say that Cisco is at a certain turning point, moving from a hardware-based company to an integrated one based on hardware and software. Cisco 200-150 VCE
In doing so, Cisco has engineered the next generation of its network management products in the form of networks based on intent. Meanwhile, as the growth of hardware sales slows down due to the workloads that change the public cloud, the company considers the Internet of things and computing as new frontiers for revenue growth.
"If you look at HPE, Dell, IBM and Cisco, all those companies are trying to reinvent themselves for this IoT world in the cloud," says Forrester's network analyst, Andre Kindness. "The traditional way of doing things is dead, they are all big enough so they do not disappear soon, but they may also have to find something else to boost them in the future, for Cisco, maybe it's IoT, maybe it's software." .
From a business perspective, Cisco is still fine. The company earned revenues of $ 49 billion in 2015 and 2016 and $ 48 billion in the fiscal year that ended in July 2017; Switching sales decreased 5% in the fiscal year, while service revenues increased 3%. Below are some of the key technology areas that the company hopes to drive a new era of network innovation in 2018 and beyond.
Networks based on intention
While the main network advances in recent years have focused on software-defined networks, in mid-2017 Cisco launched a new intent-based network (IBN) strategy that is expected to model the future roadmap for network management of the company. What is IBN? Users dictate policies and network orchestration software automatically configures and maintains the desired state of the network. In 2018, we expect the theoretical advantages of IBN to become reality as the proof-of-concept implementations are deployed.
Brad Casemore, an analyst at IDC, says Cisco also has to reconcile its somewhat unrelated IBN strategies. When Cisco launched IBN, it did so in the context of the campus network team, based on its Catalyst hardware line and the DNA Center software. Cisco says it has been doing IBN for years, although it does not call it that in the data center with its Nexus 9K router package, Application Centric Infrastructure (ACI) and Tetration analysis. "I think you'll see Cisco talking more thoroughly about how the intention-based network will extend through its portfolio, in the data center, on the campus and across the WAN," says Casemore. "I think they try to unite these narrative threads."
Kindness, the Forrester analyst, says he would not be surprised to hear Cisco apply the intention-based moniker to other management systems: intention-based security, intent-based data centers, etc.
The transition from Cisco to SaaS
In announcing their new IBN strategy, Cisco executives made a key point: they are selling the software that runs IBN in a new way. Traditionally, software running on Cisco network hardware has been sold in perpetual licenses. DNA Center, the company's IBN platform for its campus switches, can be purchased as a subscription or SaaS model.
"It's pretty obvious they're in a transition from focusing on hardware to focusing on software, and that comes with its challenges," says Amy Arnold, a Cisco user and network engineer working in the public sector in Texas. As Cisco launches its new products as DNA Center and Tetration through the software, it points out that hardware is still important. "We will still have many switching plate counts, but maybe not many," he says. Arnold says that if better software can improve uptime, reliability and allow network engineers to be more agile, then she is in favor. Casemore notes that financial investors will also be closely monitoring this transition.
The Internet of things
As traditional network hardware sales begin to stabilize, the broad Internet of Things market is an area in which Cisco expects significant growth. Cisco has already invested heavily in creating robust hardware teams that can run on IoT devices, as well as on software platforms to control IoT implementations. In 2016, Cisco purchased the IoT Jasper administration provider for $ 1.4 billion. In 2017, Cisco launched Kinetic, an IoT operations software platform that allows users to automate connections to IoT devices, extract data from them and route them for analysis. Expect Cisco to aggressively promote itself in the IoT market, both in hardware and software.

The most recent Cisco cloud strategy
After a handful of pivots, Cisco is ready to test its latest strategy in the cloud. In the past, Cisco tried to build Inter-cloud, its cloud network powered by Cisco, but surrendered in that in 2016. This time, Cisco is partnering with Google Cloud Platform to offer a hybrid cloud platform based on the code software open Kubernetes for running application containers. Cisco will allow your server's hardware systems to run Kubernetes, while offering integration with the Kubernetes service based on Google's cloud. Meanwhile, Cisco's partnership with Google is not exclusive, so it will also help customers manage connections with other public cloud providers. Because VMware is associated with AWS, Google and IBM, Cisco seems to have felt the need to establish a friendly relationship with a public cloud provider, and chose to do so with Google. In 2018, clarification could be reached about exactly what this partnership will be like and the general strategy of the Cisco cloud.
