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 provide versatile work choices for workers, and on the identical time, the functions accessed by these workers are transferring from the on-prem information facilities to the general public cloud infrastructure, and generally, it’s multiple.
These traits have considerably expanded the risk floor leading to new risk vectors within the enterprise. With cyberattacks rising in numbers and class, the job of the IT admin isn’t just harder than ever – it’s extra vital than ever. At present, the IT admin should guarantee worker productiveness isn’t impacted, that functions and networks proceed to be extremely out there, all whereas securing the enterprise.
Enabling a easy and safe zero-trust infrastructure
One of many essential challenges at present is there are a lot of islands of insurance policies that aren’t linked resulting from 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 completely different domains. Most options out there out there at present deal with enabling the end result by implementing insurance policies on particular enforcement factors within the community such because the entry swap, the firewall, the router, and so forth. The fact is that every of those are simply one in every of a number of enforcement factors that must 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 isn’t just the material that allows community segmentation; it additionally contains end-point classification utilizing AI/ML based mostly profiling, coverage analytics, anomaly detection, risk detection, and risk response. These capabilities (and extra) can be found in Catalyst Heart, with profiling and micro-segmentation additionally out there in Meraki, with extra to be added recurrently.
In June we introduced that we’re additional extending the capabilities in SDA with a brand new function known as Widespread Coverage. Widespread Coverage simply shares context throughout domains, thereby permitting finish to finish segmentation enabled by easy 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 – transferring ahead, the identical infrastructure might be leveraged to share further context corresponding to 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 turn out to be much more versatile and extensible, giving customers the power to construct material both utilizing LISP or BGP-EVPN.
What would a Widespread Coverage deployment appear to be?
Think about this state of affairs 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 pair 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 don’t seem to be allowed to entry the lifecycle administration utility. To allow this consequence at present, prospects need to construct insurance policies based mostly on IP addresses and implement them throughout the assorted enforcement factors. IP addresses are ephemeral and are vulnerable to misconfigurations, thereby leading to safety gaps. And when the IP addresses change, prospects need to undergo the guide means 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 applying infrastructure within the non-public DC the place the storage app is hosted, and the general public cloud the place the lifecycle administration utility is hosted. Each the functions i.e. the storage app and the lifecycle administration utility, might be represented as distinctive SGTs in ISE, that are then shared with the assorted enforcement factors throughout the infrastructure. Cisco Safe Entry, which is one in every of these shoppers, will leverage the SGTs to provision a coverage that may stop 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 stop 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 corresponding to healthcare, manufacturing, and retail the place this functionality is straight relevant.
How does Widespread Coverage work?
Previous to widespread coverage, prospects configured Cisco Identification Providers Engine (ISE) to assign SGTs to customers and gadgets that linked to the community, based mostly on numerous attributes like the kind of the machine, the group that the person belonged to, the posture of the machine that was used to hook up with the community, and so forth. These tags have been made out there to the community and safety infrastructure (e.g. on-prem firewall, safety providers 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 will be set wherever, with the identical consequence throughout all enforcement factors.
Now ISE can join on to the applying internet hosting infrastructure, each on-prem and within the cloud, which permits prospects to map the applying constructs to SGTs. These mappings are robotically shared, thereby permitting coverage definition based mostly fully on SGTs – a considerably less complicated expertise for IT directors.
Within the newest model simply introduced at Cisco Reside, ISE3.4 can now:
- Hook up with Cisco Software 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
- Hook up with the cloud providers 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 trendy enterprise. Many purchasers have liked and used ISE to safe their person 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 this planet who can do that. We are going to stay devoted to fixing the important challenges confronted by at present’s IT groups.
