“The Internet of Things has changed the nature of the work of network professionals. In today’s networks, the responsibilities of network professionals are no longer to secure the network connection of computers and smartphones and the security of data in servers, but to ensure that new models are increasingly available. The devices are always online and continuously available and provide protection for the network connections of these devices.
From the intelligent light switch in the building to the infusion pumps used in hospitals and oil temperature sensors on oil rigs to industrial control equipment, there are countless new devices of this kind. Connecting these devices to the network can help companies increase profits. Our report shows that by 2020, 46% of network devices will implement inter-machine communication.
Every new device has potential security holes. According to the Gartner IoT Network Survey, 35% of respondents believe that security issues are the biggest obstacle to the success of IoT projects. Our midyear cybersecurity report also showed that attackers now have the ability to infect 100,000 IoT devices within 24 hours.
For many years, Cisco has been committed to building a network that supports the Internet of Things. We believe that the influence of the Internet of Things is sufficient to fundamentally change the way the network is constructed and managed. This process will inevitably have huge technical challenges, but it will also bring a variety of business opportunities so that Cisco can create more value for customers and partners.
This is the reason why we are leading the industry in transition to an intent-based network. With an intent-based network, network professionals will be able to manage the self-activation of networked devices on a large scale and perform other management tasks. We provide new software that helps IT teams identify and locate IoT devices, make policy settings, and activate strategies on a large scale across IT and business units. Ultimately, these software can provide companies with real-time insights that drive operational efficiency.
Recently, we announced the introduction of Cisco DNA enhancements to further help you manage the ever-expanding network and extend the many benefits of Intention-Based Networks to the Internet of Things. We will do our best to help you migrate to an extended enterprise network environment that is highly dependent on the Internet of Things. These enhancements have made great progress in the following three areas:
1, through the identity service engine to improve visibility and security of the Internet of things
If you do not see the threat, you cannot protect it. As a result, Cisco is committed to providing greater visibility and insight into IoT devices connected to the network to address the biggest obstacles to IoT adoption.
Cisco Identity Services Engine (ISE) is software that identifies when a device is connected to the network and reports detailed device data (such as manufacturer, model, and installed software). ISE can control everything that accesses the corporate network through wired networks, wireless networks, and VPN connections, and feeds user and device details back to the DNA center to generate more practical intelligence.
In the latest ISE software upgrade, Cisco has doubled the number of IoT devices and user device groups that ISE can automatically identify and classify, enabling support coverage for those using industrial and building automation communication protocols such as BACNet, Profinet, and CIP. And Modbus) equipment. To successfully manage a large number of new devices that flood into the network, you must first ensure that the network recognizes these devices.
2. Extending software-defined access (SD-Access) to extended enterprises
In June last year, we introduced SD-Access. As a revolutionary new management model, it can help network administrators to configure and manage access rights in an automated manner to effectively respond to the explosive growth in the number of networked devices. With SD-Access, you will be able to simplify the deployment of network segments to more easily protect your network, data and applications. This new segmentation method no longer defines rules based on the physical characteristics of the network, but rather expresses network rules in a way that companies think about business strategies. Networks built using SD-Access are safer, more flexible, and easier to maintain and manage. This is indispensable for us to deal with the dynamic changes of today's users and devices.
Today, Cisco extends the advantages of SD-Access from the campus to extended enterprises (such as distribution centers, warehouses or manufacturing plants) and outdoor environments (roads or oil rigs). The latest DNA center software version can support some industrial Ethernet switches, compact switches and all-digital building switches.
As a result, IT departments can easily extend network policies to outdoor environments and non-office space, and avoid additional management costs; business operations teams will also be able to manage their own terminals. The network operations team will no longer need to manage multiple networks, and IT personnel can manage and protect the operating environment with confidence.
3. Make the network a tool for business optimization with Operational Insights
Operational Insights is our new cloud-based service that leverages network intelligence to optimize and protect business processes. Our various tools collect data from sensors and provide IT teams with location analysis so they can track assets and IoT devices. On this basis, the network will be able to automatically notify the appropriate personnel to take specific actions at specific times based on the sensors and location data. This service is ideal for industries that require increased safety and optimized operations, such as the medical industry, manufacturing, and retail. For example, hospitals can locate important medical devices in real time, and retailers can determine whether the expensive items returned by customers are actually sold by themselves.
Operational Insights allows your business to be familiar with capital equipment and has practical insights in addition to basic connectivity information.
All in all, these enhancements allow you to manage connected devices through a single network platform, which is very different from the traditional port-based and complicated rules most network administrators are familiar with. These intent-based web tools not only make device management more intuitive, but they are also essential to address the explosive growth in IoT device connectivity. If you need more help with IoT devices and deploying intent-based networks, Cisco Services and the Cisco Partner Ecosystem can provide a dedicated team of experts to help you minimize risk, accelerate innovation, and increase your return on investment.
In addition to the above new technologies, our team has also been committed to launching more intent-based network innovation technologies, including the new Catalyst 9500 supporting 100G services, the incomparably intelligent Aironet 4800 wireless access point, and enabling customers to access any Get a world-class SD-WAN new routing software subscription service on the platform.
