Identity security

Digital business processes in the context of organizations, end users, and machines in shared systems require robust identity security management

Coveted goods on the Darknet

Woman lying on her stomach and typing something in her tablet. She is holding a gold credit card in her hand.

Is the person logging into the intranet actually authorized to do so? Is the software which issues a command to a computer authorized to do this? In the analogue world, we prove our identity with a passport and a driver's license. In the digital world, people or objects are clearly identified using a digital identity, which protects against misuse and makes work difficult for hackers.

However, on the web there is one commodity for which sellers are consistently achieving higher prices: digital identities and digital certificates. Machine identities are particularly popular on the Darknet. On marketplaces such as Dream Market, BlockBooth, and Galaxy3, SSL/TLS certificates cost up to several thousand US dollars. At the start of 2019, IT security researchers from Kaspersky Lab Material found more than 60,000 stolen existing digital identities on the Darknet shop Genesis.

If misuse of a digital identity is to be prevented, identity data must be securely generated, securely stored, and securely processed. But users are already complacent when choosing the right password. Four out of five data attacks take place due to simple and hackable character combinations. T-Systems offers various processes and solutions with which companies can generate digital identities, secure websites, and passwords.

Your digital ID: certificates and public key infrastructure

Man stands in a room next to a glass and looks directly into the camera.

In addition to issuing certificates, the full-service Trust Center also develops complex public key infrastructures (PKI) for industrial customers, authorities, countries, and organizations. The security and performance of individual solutions and products from the Trust Center are safeguarded through regular certifications. The team works in compliance with EU regulation on electronic identification and trust services (eIDAS), as well as the specifications of the European Telecommunications Standards Institute (ETSI). Furthermore, gematik approval for the electronic health card is available.

The Internet of Things (IoT) and machine-to-machine communication in connection with cloud and Industry 4.0 applications are only possible if millions of communicating things and machines are clearly virtually mapped through the automated mass issuance of digital identities.

Your secure authentication: access management

Input field for password against a green background

The use of a two-factor authentication solution enables companies to optimally secure access to their data in line with their protection requirements.

The intelligent service generates one-time passwords to log into online services and protected systems, is easy to integrate, and offers increased security through strong two-factor authentication, as well as cost optimization through minimal bureaucracy. It enables users to access many systems and services with a single login process.

Securing your most valuable identities: privileged account management

A passport is on a boarding card.

Privileged account management allows companies to safeguard administrative access to their most critical IT resources (on-premises or in the cloud). PAM solutions help companies with the storage, management, and monitoring of privileged accounts and their credentials in a secure digital safe that fulfills compliance requirements (ISO 27001, BSI basic security...).

By creating a central secure storage space for privileged identity information, companies can:

  • Check and monitor the use of privileged accounts (where necessary also using third-party providers)
  • Eliminate hard-coded plain text passwords in machine-to-machine communication
  • Equip automated processes with one-off, scalable identities
  • React to identity theft of admin identification in real time

Privileged Identity Protect Pro

Risk-based authorization and session management for privileged accounts to protect against attacks.

  • Scanning for privileged accounts
  • Central security of admin passwords and SSH keys
  • Role-based access controls
  • Dynamic rotation of admin passwords 
  • Session monitoring
  • Continuous threat analysis

Secure keys for digital identities: smart cards and secure elements

A man with a laptop in his hand and a woman standing in a server room. The woman points to visualized records.

We carry it in our wallets and coat pockets, use it on our travels, or use it for checking into our office PC. But hardly anyone is aware that, by doing this, they are entrusting their personal data to one of the most secure operating systems on the IT market: the TeleSec Chipcard Operating System – or TCOS. The highly-secure smart card operating system is certified by the Federal Office for Information Security (BSI).

TCOS for passports or ID cards has been checked in accordance with the internationally recognized process of “Common Criteria”. It is therefore one of the most secure systems for international travel documents. More than 100 million passports, personal and company ID cards, digital tachographs, and electronic tickets in Europe are equipped with the highly secure TCOS operating system.

TCOS encrypts personal data

The PACE protocol protects against the unauthorized reading of data via a contactless interface. The chip on identity documents has a passport photo and fingerprints stored on it, among other things. The software organizes the encryption, the secure readout of personal data, and protects these against unauthorized access. TCOS is also able to safely store keys and calculate the cryptographic algorithm within the chip. Securely imported keys never have to leave the chip card again.

TCOS fulfills the toughest requirements

The combination of the TeleSec chip-card operating system and the security chip has been conceived with international requirements for electronic identity documents in mind. But we don't stop there: working with various chip manufacturers, we are continuously checking the use of new smart card technologies, as well as application areas. Examples of application areas are mobile security, company ID cards, electronic driving licenses (European driver's license), security for cloud solutions, and security for data in web solutions, such as intelligent electricity meters (smart meters).

TCOS Smart Cards

Identity systems for electronic passports and national ID cards. Smartcard-based project solutions.

Identity security at the highest level: trusted IT operations

Trust Center

A trust center serves as an independent certification point and trusted authority for the electronic exchange of data. T-Systems is accredited by the German Federal Network Agency (Bundesnetzagentur) as a trusted service provider. In order to guarantee the highest possible security, all Trust Center services are based on the latest technologies from the security sector – whether it is for the encryption of data and networks or for two-factor authentication.

As the first German Trust Center, T-Systems offers security services as a trusted independent service provider, based on an ISO-certified security concept. The Trust Center, accredited by the German Federal Network Agency, serves as an independent certification point and trusted authority for the electronic exchange of data.  

All services are backed by a highly secure environment across geo-redundant data centers based in Germany. If one area has an outage, a second data center automatically steps in. All data, the entire IT infrastructure, and all network connections are mirrored in this data center. In this way, not only are we safeguarding a reliable and highly-available operation but we are also complying with the highest German and European requirements for data protection and security.

The creation of the certificate for this is carried out in our own Trust Center and exclusively by trained and security-screened personnel. This produces certificates of the highest security level. T-Systems guarantees a secure, electronic exchange of data, even for highly-sensitive information.
