About The Customer
This Eastern Europe agency (agency) is globally renowned for providing elite defense services that safeguard its country’s residents, visitors, infrastructure, and institutions. As one of many government departments supporting the country’s overall defense framework, this agency has embraced next-generation Unified Communications (UC) technology to help their subject matter experts collaborate in high-quality data and voice communications environments necessary to help sustain its mission.
The Challenge
The agency’s data and voice network runs in a 4G environment managed by a leading telecommunications system integrator (SI). This network supports hundreds of government teams and users, and the SI regards this community as equivalent to mobile subscribers. With the security challenges in today’s geopolitical climate, the communications integrity required for effective national defensive activities is of utmost importance. As a result, the agency approached a select few industry vendors regarding viable solutions for their mobile network and user monitoring needs. Monitoring call quality from the subscriber’s perspective was atop this list. Any call quality impairments in this military environment could jeopardize the agency’s mission, assets, and the very citizens of this country. As a result, the agency wanted to enhance monitoring of their 4G mobile network performance to validate the service responsiveness and integrity provided by their SI. The agency specifically wanted to monitor LTE/EPC Network interfaces (e.g., S1MME, S5/S8, S10, and S11) and IMS/ VoIP/VoLTE protocols (e.g., Cx, IMS, IMS DNS, SIP, Rx, and RTP). Only then would they be able to visualize the service quality being provided by their SI to their government users. As part of their overall requirements, the agency also identified a need to uncover and analyze specific calls that failed to deliver required performance. Specifically, they wanted the ability to quickly focus and analyze calls with unique parameters, including merging calls for call correlation. While the government recognized the importance of this project, the relatively small user base and highly focused scope meant there was a desire to acquire the best technical solution in the most efficient, economical way.
The Solution
The agency is addressing their mobile network voice and data monitoring challenges by deploying the NETSCOUT® nGeniusONE Service Assurance platform, with this solution located at both their SI’s facility and their own location. In addition, the agency is using Iris Session Analyzer (ISA) software to uncover and analyze specific calls and sessions that fail to deliver required performance. The smart analytics provided by nGeniusONE and ISA each leverage smart data generated by NETSCOUT Adaptive Service Intelligence™ (ASI) housed in commercial-off-the shelfbased (COTS) InfiniStreamNG (ISNG) software appliances. With nGeniusONE, the agency is proactively monitoring their LTE/ EPC and IMS/VoIP/VoLTE services. ASIgenerated smart data delivers insights to improve government network and service performance, also providing detailed IP-level views into the control and user planes, as well as network usage and behavior. The agency is taking advantage of nGeniusONE’s smart analytics for UC to monitor DNS, SIP, and RTP, specifically benefiting from the ability to provide Quality of Service (QoS) information, identify transmission errors, and present Mean Opinion Score (MOS) data for voice quality. The agency also relies on customized nGeniusONE Utilization Reporting provided by NETSCOUT Delivery Services, while also leveraging workflows originating from Dashboard views into network management, individual call views, and down to packetlevel details. In addition, the agency is correlating signaling and media to deliver a more complete picture of network issues, with Iris Session Analysis merging calls for call correlation. As a result, the agency can quickly isolate root cause and remove any performance barriers impacting call quality for users.

Enhancing Security and Compliance in Remitly's Global Money Transfer Service with Fastly
Remitly, an online remittance service, was faced with the challenge of securing its proprietary global transfer network. The company needed a security solution that could meet PCI requirements and protect customers' sensitive transactions through its mobile application. The solution had to be capable of defending against new and emerging attack types without impacting performance. Remitly also had to deal with irregular traffic patterns, such as a sudden spike in account transfers from a small network segment on the Pacific coastline of South America. The company needed to determine in real time whether such traffic indicated an attack or valid requests. A traditional web application firewall (WAF) would not be able to distinguish this traffic, potentially leading to customer frustration if the IP was blacklisted.

Major Aerospace Company Automates Asset Management
The O&M division of an aerospace and global security company was using spreadsheets to manually track more than 3,000 assets assigned to students and staff. Maintaining audit trails for this high volume of equipment became increasingly time-consuming and challenging. The chore involved knowing precisely what equipment was on hand, what had been issued, its location and the name of the custodial owner of each item. Every aspect of this task was carried owner of each item. Every aspect of this task was carried out by individuals with spreadsheets. Manually documenting the full lifecycle of each asset added to the burden. This included tracking maintenance requirements and records, incidents and damages, repairs, calibrations, depreciation, and end-of-life data.

Securing a Large Data Center in the EMEA Region: An IoT Case Study
A leading data-center operator in the EMEA region, with multiple facilities spanning over 25,000 square meters, faced significant security challenges. The operator experienced interruptions in their internal IT network due to unsupervised work of third-party technicians. Despite having a high-end building control system that provided 24x7 monitoring and control to all the building’s infrastructure, the data center was vulnerable from a cyber perspective as it was connected to the IT network infrastructure. The operator launched an urgent OT cyber security project that included both IT-OT network segmentation and OT network asset mapping and anomaly detection. The main objectives were to harden the security of the server systems, secure the facility’s power supply and server cooling system, strengthen the segmentation between building and operational systems, create a visual OT network map, and set up a system for presenting supply-chain attacks that may threaten the data center through equipment vendors’ maintenance activities.

Leveraging Graph Technology for Enhanced Cybersecurity: A Case Study on MITRE's CyGraph
MITRE, a federally-funded, not-for-profit company that manages seven national research and development laboratories in the United States, was grappling with the challenge of managing an influx of cybersecurity data. The constant changes in network environments were impacting the security posture of U.S. government agencies. Intrusion alerts, anti-virus warnings, and seemingly benign events like logins, service connections, and file share access were all potentially associated with adversary activity. The cybersecurity researchers at MITRE needed to go beyond rudimentary assessments of security posture and attack response. This required merging isolated data into higher-level knowledge of network-wide attack vulnerabilities and mission readiness. The challenge was not the lack of information, but the ability to assemble disparate pieces of information into an overall analytic picture for situational awareness, optimal courses of action, and maintaining mission readiness. The team also struggled with fully comprehending a given security environment and mapping all known vulnerabilities.
