Affordably reduce the attack surface of evolving telecommunications infrastructure

An Affordable Approach for Reducing the Attack Surface of the Evolving Telecommunications Infrastructure

Telecommunications service providers are constantly launching new service offerings that require new infrastructures and cloud technologies. This requires managing the security posture in hybrid and complex environments, many times having to use different tools for each.

Guardicore has taken an entirely new approach that simplifies the challenge and makes the process significantly more effective. With Guardicore Centra, telecommunications service providers can segment their most important assets by focusing on three steps:

  • Visualize
  • Build
  • Enforce

Let’s look at each of these in-depth.

Visualize Telecommunications Infrastructure

Adonias Filho, Senior Sales Manager at Italtel, a leading telecommunications provider and Guardicore strategic partner, notes, “Segmentation is a need that has long been felt – but unfortunately never [previously] been achieved in an effective way. The micro-segmentation projects have been catastrophic, because it was not possible to segregate something if you don’t know exactly what it is.”

In other words, you can’t design an effective segmentation program if you don’t have complete visibility into application interdependencies and communication flows. Guardicore Centra rectifies that issue, making it quick and easy to visualize and secure on-premise and cloud workloads.

Adonias adds, “The main point Guardicore brings to this context is visibility. Starting out from visibility, one can propose rules for separation, segmentation, micro-segmentation, and nano-segmentation. With Guardicore, I was able to implement micro-segmentation rapidly and with stability – that is to say, without any problems.”

Centra collects and maps detailed information about application functionality, communication flows, and dependencies. These maps make it simple for security teams to assess potential for exposure and identify when assets have been compromised. They can also define expected behavior and identify areas where additional controls can be applied to reduce the attack surface.

Build Rules With Ease

Telecommunications service providers feel constant pressure from regulations and industry standards. In addition, they operate complex infrastructures. The two issues combine to create a challenging situation, wherein managing/enforcing security controls and reporting on risk across a diverse set of technologies on multiple platforms is resource intensive. Moreover, frequent reconfiguration needs can result in production downtime.

Because of these security challenges, telecommunications communities often end up with security gaps and broad attack surfaces. This leaves them vulnerable to illicit activities.

With a single click, Guardicore Centra generates automated rule suggestions and enables organizations to quickly build strong security policies. Intuitive workflows and a flexible policy engine allows for continuous policy refinement and reduces costly errors.

Enforce Consistent Security Controls

Guardicore Centra helps Telecommunications companies maintain consistent security controls, regardless of their underlying infrastructure. Leveraging software-based overlay segmentation technology enables telecommunications companies to achieve network segmentation in record time, with significant risk reduction across all types of infrastructure.

What’s more, Guardicore provides integrated breach detection and response capabilities, enabling businesses to see policy violations in the context of an active breach. Data exfiltration in particular – a threat which telecommunications services are vulnerable to due to the new infrastructure and technologies they support – requires the kind of protection that Guardicore provides.

All an attacker needs is an opening to a single network-connected resource in order to be able to move laterally across the network. At that point, they can access the entire infrastructure and destroy, ransom, or steal any data they want.

As Adonias comments, “Protection in data centers and clouds defends, at the origin, the companies that subcontract provider services. Why try to invade directly a large company, with its defenses up to speed, if there is an open door to it through a provider from whom it outsourced – for example its financial department?”

With Guardicore, organizations can contain this type of attack before it spreads across the company, keeping it from becoming a true disaster. Using Guardicore Centra, telecommunications providers have been able to dramatically shrink their attack surfaces across thousands of critical servers without service disruptions, significantly reducing risk and impact of security breaches.
