For many organizations, Wi-Fi access is no longer a luxury. Employees need flexible access as they roam about the office, and customers and partners expect to connect whenever they are on site. But providing unsecured access opens a host of potential security problems if access points aren’t rigorously monitored, patched and maintained. As the number of access points grows, it’s easy to let this important maintenance task slip.
Security teams are so busy fighting fires that preventing maintenance is often overlooked. Kaspersky Labs recently analyzed data from nearly 32 million Wi-Fi hotspots around the world and reported that nearly 25% had no encryption at all. That means passwords and personal data passing through those devices can be easily intercepted by anyone connected to the network.
Virtual private networks (VPNs) are one way to keep things secure, but 82% of mobile users told IDG they don’t always bother to use them. The profusion of software-as-a-service (SaaS) options encourages this. Gartner has estimated that by 2018, 25% of corporate data will bypass perimeter security and flow directly to the cloud.
The Wi-Fi landscape is changing, thanks to mobile devices, cloud services and the growing threat of cyber attacks. This means that Wi-Fi security must be handled holistically, with a centralized approach to management and an architecture that integrates both endpoint protection and network traffic analysis. Cisco has spent more than $1 billion on security acquisitions since 2015, and it has put in place the necessary pieces to provide this integration.
Cisco Umbrella, which the company announced last month, is a new approach to securing the business perimeter that takes into account the changing ways people access the internet. Umbrella gives network and security managers a complete picture of all the devices on the network and what they are doing. For example, by combining Umbrella with Cisco Cloudlock Cloud Access Security Broker technology, organizations can enforce policies customized to individual SaaS applications and even block inappropriate services entirely. They can also block connections to known malicious destinations at the DNS and IP layers, which cuts down on the threat of malware. Umbrella can even discover and control sensitive data in SaaS applications, even if they’re off the network.
Cisco’s modernized approach to security also uses the power of the cloud for administration and analysis. Cisco Defense Orchestrator resolves over 100 billion Internet requests each day. Its machine learning technology compares this traffic against a database of more than 11 billion historical events to look for patterns that identify known malicious behavior. Defense Orchestrator can thus spot breaches quickly so they can be blocked or isolated before they do any damage. Thanks to the cloud, anonymized data from around the Internet can be combined with deep learning to continually improve these detection capabilities. Predictive analytical models enable Cisco to identify where current and future attacks are staged. In other words, Cisco’s security cloud gets smarter every day.
Umbrella can integrate with existing systems, including appliances, feeds and in-house tools, so your investments are protected. It’s built upon OpenDNS, a platform that has been cloud-native since its inception more than a decade ago. It’s the bases for Cisco’s security roadmap going forward.
A great way to get started with Cisco Umbrella is by revisiting protection on your Wi-Fi access points. We know Cisco networks inside and out, so let us put you on the on-ramp to the future of network security.
