Retail company –

Microsoft Azure Cloud

Situation
Approach
Result

As part of an extensive digitalization project, a retail company will be relying heavily on the Microsoft Azure Cloud in future. The aim is to gain broader access to technologies, establish more transparent cost structures within the company and become less dependent on local data centers. Due to different levels of knowledge within the company, a central cloud competence center is to be defined and established in order to empower individual teams and business units.

TEAL supports the customer in the coordination and overarching planning for the central competence center. The first step was to determine the needs of the internal customers and to ascertain their level of knowledge. Services must be established in order to automatically develop deployable infrastructure-as-code services, an internal consulting and onboarding team must be set up to ensure a secure and simple start in Azure and a connectivity team must be implemented for the standardization and operation of network services. All operational tasks must be largely automated and handed over to an external provider.

Together with the customer, TEAL developed an appropriate operating model including all associated processes and standards. These were tested, improved and introduced as part of a hypercar. Operational tasks were outsourced to an external service provider where possible and appropriate.

International development partner of the automotive industry

Situation
Approach

An internationally active development partner in the automotive industry for complex metal and hybrid structures with a large number of locations and more than 10,000 employees approached us to secure the complex and globally distributed infrastructure. In the course of security-relevant incidents in the said industry, TEAL was commissioned to check and secure the Active Directory infrastructure. TEAL was also commissioned to make preparations for the use of cloud services.

For this purpose, a detailed analysis of the customer’s security infrastructure was undertaken, risks were evaluated and weighted, and finally an action plan was proposed. TEAL was then commissioned to implement this plan. For this purpose, we designed a new security concept (TIER0), which we implemented with the customer in a cooperative atmosphere.

The security aspects of the customer infrastructure are thus conceptually re-implemented and secured, and at the same time prepared for the use of cloud services. This minimizes potential attack risks while at the same time future-proofing the core infrastructure.

Company from the public sector

Situation
Approach
Result

After in-depth online research, a government agency approached us to analyze and secure their existing Active Directory infrastructure for full protection against cybersecurity attacks.

Due to the ever-increasing security awareness factor in the media, the customer wanted to restructure in this area and stabilize the basic pillars of infrastructure and identity management through external expertise.

In order to work out a suitable solution, we first carried out a three-day assessment in the customer’s environment to find out how possible attackers could get into the company’s network and how the customer could ideally protect itself against this. This resulted in a roadmap with recommendations and concrete implementation measures to effectively increase infrastructure security.

In further steps, implementation packages were derived, structured and prioritized. These packages were then implemented together with the customer. This included both organizational and technical measures and individualized concepts, which were adapted on the basis of the customer’s environment and other circumstances.

First, we started by establishing the common SAE basics. These include both the tiering concept and the introduction of PAW systems combined with consistent account separation. Extensive info is also available in our blog series on (E)SAE.

In the future, we will use the Enforce Suite to achieve extensive and permanent system hardening of the infrastructure as well as compliance with established hardening standards such as BSI or CIS.

International Manufacturing Company

Situation
Approach

The goal was to harden and secure an existing Active Directory of an international company with 5,000 employees in the manufacturing industry according to SAE standards. In addition, PAWs were to be introduced for Tier 0 and Active Directory objects were to be assigned to the Tiers in order to implement all measures to make potential lateral movement more difficult.

In order to find a suitable solution, we first conducted a three-day assessment in the customer’s environment to determine how potential attackers could gain access to the company’s network and how the customer could effectively protect itself against them. The corresponding findings were then elaborated and evaluated by us. Our consultants were then able to implement these together with the operations team and carry out the process changes.

Meanwhile, the customer can administer its secured Active Directory structure through special secured PAWs (including multi-factor authentication) and has also established an encapsulated and hardened Tier0 environment.

Telco Group –

Infrastructure modernisation

Situation
Approach
Result

In order to increase the customer functionality of the largest IP TV solution in Germany with nearly 2 million customers even further, the provider decided to implement a new version of the Microsoft IP TV solution. Along with the new release, the basic infrastructure was to be extended, modernized and to be brought up to the current software version.

TEAL supported the modernisation of the infrastructure by upgrading the server operating systems as well as their management systems (system centre configuration, operations, and data protection manager) in several environments with a total of over 1,000 servers. Furthermore, a modern certificate infrastructure, secured by HSM modules, was implemented and transferred to operations.

Thanks to the comprehensive infrastructure modernisation project, the basis was created to operate the new version of the IP TV solution securely, steadily and at a high performance. After the successful launch of the new version, the provider was able to offer their customers mobile access for the first time as well as an enhanced video-on-demand platform with many new and enhanced features.

Public data centre operator –

Linux RPM build pipeline

Situation
Approach
Result

The development team of a public data centre operator in Austria couldn’t focus its full capacity on the development of new features and products because, with each new build, it had to carry out numerous manual steps until the packages were developed, tested and deployed. To resolve this drawback, an automated testing and deployment pipeline was to be implemented.

TEAL employees developed a standardised, fully automated and monitored build environment based on Red Hat RPM and augmented by the products of GitLAB, Jenkins and Mock. A distributed GIT instance stores and manages the source code which can be automatically compiled in the build environment by Jenkins at any time. Subsequently, MOCK processes create and check new RPM packages in a rule-based manner which can then be rolled out to the target systems via Satellite.

The client is now able to use the capabilities of its development team more efficiently to further develop business applications. At the same time, the number of errors was reduced thanks to the fully automated processes and test procedures and the deployment time for new releases was significantly reduced.

INTERNATIONAL COMMERCIAL VEHICLE MANUFACTURER –

SECURE ADMINISTRATION OF THE ACTIVE DIRECTORY LANDSCAPE

Situation
Approach
Result

One of the leading manufacturers for commercial vehicles with more than 30,000 employees was faced with the challenge of implementing a comprehensive strategy program to realign its IT infrastructure and increase IT security. Protecting the Active Directory has a major impact on this increase in security. The corporation has a blueprint based on the Microsoft ESAE approach which it uses for this. The aim of the project was to adapt and implement this blueprint to the local circumstances.

TEAL supported manufacturer by analyzing the company blueprint, designing the target architecture and implementing the Secure Administration Environment (SAE). The solution consists of three Active Directory Forests for production (“Gold Forest”), administration (“Red Forest”) and the hypervisor (“Iron Forest”) with corresponding admin tiering. Each tier is protected by numerous measures such as 2-factor authentication, Privilege Administration Workstations (PAWs), Security Baseline GPOs and secure operating processes. This provides an exceptionally high level of protection against Pass the Hash and Pass the Ticket attacks.

The project has significantly increased the security level of all high-priority IT assets and has thus laid the foundation for further measures to increase IT security. Together with TEAL, the commercial vehicle manufacturer was not only able to implement the corporate blueprint, but also improve it. The SAE architecture has thus become a key element in the IT security of the entire corporation.

IT service provider insurance –

Secure Global Authentication Platform (based on ESAE)

Situation
Approach
Result

As part of a major strategy programme, the international insurance group with 40,000 employees restructured its IT portfolio. The goal was to improve co-operation among the group’s individual companies and to intensify the use of global services. These services were to be recreated centrally and operated as safely as possible. The first step was to be the development of a global authentication platform for both Kerberos-based and token-based services.

TEAL assisted the client in defining the architecture and implementation of this global authentication platform in two new co-located data centres. The authentication platform consists of an active directory architecture based on Microsoft’s Enhanced Security Administrative Environment (ESAE, you can find out more about this in our blog) for Kerberos-based services and an ADFS platform for token-based applications. Administrative rights are granted only temporarily by a Privileged Access Management (PAM) solution to minimise the risk of being attacked (and from subsequent consequences) due to stolen passwords. By almost exclusively using Windows Server 2016 Core, the points of attack were reduced further. Hereafter, the monitoring of the use of high privileges can be further improved by the complete integration in an SIEM system and the pairing of the distribution of rights to the change and incident tools.

Thanks to the new authentication platform based on ESAE, the foundation for the globally shared services has been laid. These systems can now be operated within a secure environment and made available to the end user.
