One of many high considerations I hear from prospects is that they’re nonetheless grappling with level options deployed in the course of the pandemic that served time-sensitive wants however have left IT groups with an inefficient and complicated infrastructure framework. Think about this: 94% of enterprises supply versatile work choices for workers, and on the identical time, the functions accessed by these workers are shifting from the on-prem information facilities to the general public cloud infrastructure, and normally, it’s a couple of.
These traits have considerably expanded the menace floor leading to new menace vectors within the enterprise. With cyberattacks rising in numbers and class, the job of the IT admin is not only harder than ever – it’s extra essential than ever. Right now, the IT admin should guarantee worker productiveness isn’t impacted, that functions and networks proceed to be extremely accessible, all whereas securing the enterprise.
Enabling a easy and safe zero-trust infrastructure
One of many primary challenges right this moment is there are numerous islands of insurance policies that aren’t linked on account of office modernization (i.e. IT managed and unmanaged endpoints), hybrid work (distant and on-prem employees), and transition to cloud. This disconnectedness creates a necessity for distributed belief boundaries that minimize throughout totally different domains. Most options accessible out there right this moment deal with enabling the end result by implementing insurance policies on particular enforcement factors within the community such because the entry change, the firewall, the router, and so forth. The fact is that every of those are simply certainly one of a number of enforcement factors that should be supported throughout the campus, information heart, department, and cloud.
One of many key tenet’s of Cisco’s zero trust-based strategy to securing the community is Software program Outlined Entry (SDA). SDA is not only the material that permits community segmentation; it additionally contains end-point classification utilizing AI/ML primarily based profiling, coverage analytics, anomaly detection, menace detection, and menace response. These capabilities (and extra) can be found in Catalyst Heart, with profiling and micro-segmentation additionally accessible in Meraki, with extra to be added usually.
In June we introduced that we’re additional extending the capabilities in SDA with a brand new function referred to as Widespread Coverage. Widespread Coverage simply shares context throughout domains, thereby permitting finish to finish segmentation enabled by clean and area agnostic coverage creation and enforcement. It begins with constructing our coverage constructs round a key Cisco Innovation – the Safety Group Tag (SGT), which is extensively adopted throughout Cisco and third-party merchandise. The SGT is only one kind of context – shifting ahead, the identical infrastructure will probably be leveraged to share extra context reminiscent of posture of the end-point and Operation System (OS) operating on end-points.
We additionally introduced we’re evolving the segmentation constructs in SDA to change into much more versatile and extensible, giving customers the flexibility to construct material both utilizing LISP or BGP-EVPN.
What would a Widespread Coverage deployment appear like?
Think about this situation within the monetary vertical – an IP Digital camera in a financial institution must entry two functions: 1) one within the cloud for lifecycle administration of the software program operating within the digital camera and a couple of) one other within the on prem datacenter (DC) to retailer the video feed. These movies ought to solely be accessible by particular surveillance personnel and solely whereas they’re within the financial institution. Distant entry to the movies shouldn’t be allowed for safety and regulatory causes.
Moreover, surveillance operators don’t handle the cameras, so they aren’t allowed to entry the lifecycle administration software. To allow this final result right this moment, prospects need to construct insurance policies primarily based on IP addresses and implement them throughout the assorted enforcement factors. IP addresses are ephemeral and are liable to misconfigurations, thereby leading to safety gaps. And when the IP addresses change, prospects need to undergo the handbook strategy of updating the coverage throughout all of the related enforcement factors.
The widespread coverage structure allows prospects to configure ISE to hook up with the appliance infrastructure within the personal DC the place the storage app is hosted, and the general public cloud the place the lifecycle administration software is hosted. Each the functions i.e. the storage app and the lifecycle administration software, will probably be represented as distinctive SGTs in ISE, that are then shared with the assorted enforcement factors throughout the infrastructure. Cisco Safe Entry, which is certainly one of these shoppers, will leverage the SGTs to provision a coverage that might forestall the distant surveillance personnel from accessing the video storage app that’s on-prem. The on-prem firewall, which may very well be one other enforcement level that consumes the context, will forestall the surveillance personnel from accessing the lifecycle administration app within the cloud, whereas permitting the digital camera to take action. There are numerous different verticals reminiscent of healthcare, manufacturing, and retail the place this functionality is immediately relevant.
How does Widespread Coverage work?
Previous to widespread coverage, prospects configured Cisco Identification Companies Engine (ISE) to assign SGTs to customers and units that linked to the community, primarily based on numerous attributes like the kind of the machine, the group that the consumer belonged to, the posture of the machine that was used to hook up with the community, and so forth. These tags have been made accessible to the community and safety infrastructure (e.g. on-prem firewall, safety companies edge) to implement insurance policies by both passing the tag within the information path, which allowed the answer to scale the efficiency of the enforcement factors; or by sharing the bindings within the management aircraft, for leverage by the broader safety ecosystem throughout Cisco and third-party platforms.
Widespread Coverage considerably simplifies the method. Coverage could be set wherever, with the identical final result throughout all enforcement factors.
Now ISE can join on to the appliance internet hosting infrastructure, each on-prem and within the cloud, which permits prospects to map the appliance constructs to SGTs. These mappings are routinely shared, thereby permitting coverage definition primarily based fully on SGTs – a considerably easier expertise for IT directors.
Within the newest model simply introduced at Cisco Reside, ISE3.4 can now:
- Connect with Cisco Utility Coverage Infrastructure Controller (APIC)
- Uncover the end-point teams (EPGs) and end-point service teams (ESGs) and permit prospects to map these constructs to SGTs
- Connect with the cloud companies suppliers (AWS, Azure, GCP) and on-prem virtualization infrastructure (vCenter) to find the workload and VMs, and map these to SGT
A continued dedication to the challenges of IT groups
The sharing of context enabled by widespread coverage permits prospects to leverage ISE to bridge networking and safety domains, which is important for making certain complete zero belief safety outcomes for the fashionable enterprise. Many shoppers have cherished and used ISE to safe their consumer and machine entry to the community infrastructure. Widespread coverage enhances ISE to increase the identical worth proposition to functions and workloads, each on-prem and within the cloud. Cisco is the one firm on the planet who can do that. We are going to stay devoted to fixing the important challenges confronted by right this moment’s IT groups.
