Zero trust architecture has risen in cybersecurity relevance over the last stint of time, especially as work becomes more remote, data becomes more digitized, and processes become more cloud-based. This kind of digital security model helps protect information from both malicious and accidental security breaches, which is a growing priority for organizations everywhere. Without constant and reliable security, companies leave their business vulnerable to cybercriminals and other threats that can cause irreparable damage.

For companies that want to improve their security while keeping their business as efficient as possible, there are key components and functions one must consider to have the best results. Read on to learn about zero trust architecture and how modern businesses use it to proactively protect their people and data.

What Is A Zero Trust Architecture?

Zero trust architecture is a digital security model that requires all users and devices to be authenticated and authorized continuously in order to access information, applications, and data. Such authorization limitations apply to users inside and outside of an organization to prevent both intentional or unintentional breaches in a network. Essentially, a zero trust network always assumes that the network faces hostile threats, both internal and external.

Remote work, hybrid-cloud resources, and other business communication practices that rely on connectivity are bringing zero trust architecture to the front of cybersecurity. Especially as digital transformation sweeps the workforce and business worldwide, companies must have secure networks and internet access to competitively perform at scale. This architecture uses tools and principles like Zero Trust Network Access (ZTNA), which makes it possible for devices and other endpoints to remain secure, even spread across multiple locations used by dozens of different people. This helps businesses stay productive, efficient, and most importantly, safely connected.

Wie Zero-Trust-Architekturen funktionieren

A zero trust architecture framework uses modern technology to identify and verify users and systems that seek to access a network or other data endpoint. Such technology includes multi-factor authentication, next-generation endpoint security, and cloud workload technology, all of which protect endpoints like the cloud, email, encrypted data, and a myriad of other potential targets. A zero trust network is designed to:

  • Log and inspect all network traffic of an organization
  • Limit and monitor access to the network
  • Continuously verify network assets

You may be wondering how this type of security is different from others, and while there are other ways to protect your data, a zero trust system cuts out as much risk as possible by rejecting the idea of “trust by verify.” It’s easy to want to trust users and even commonly used devices—this often appears to be more convenient, too. But this mindset leaves more room for human error at best and severe intentional damage or leakage at worst.

A zero trust system removes the risk by assuming all devices or users need to be authenticated before accessing sensitive systems or data, no matter how trustworthy the user or convenient the device is. What makes zero trust so appealing is how it actively authenticates and verifies without slowing down connectivity or workflow. The right system will also enforce specific procedures that protect your security, such as creating accounts with different levels of accessibility according to your role and authority in an organization.

With the important task of ensuring that all users or applications are safely supporting an IT infrastructure, zero trust architecture prioritizes real-time insight into every participant’s or ecosystem component’s status, such as factors like:

  • Geological location
  • User ID & type
  • Credentials
  • Endpoint hardware
  • Software and firmware updates
  • Installed applications on the endpoint
  • Risk mitigation through monitoring and other security detectors
  • Behavioral patterns in users

Brauchen Sie Zero Trust?

  1. Die Sicherheitslandschaft entwickelt sich rasant. Damit wachsen auch die Herausforderungen, denen sich Unternehmen bei der Entwicklung robuster Cybersicherheitsmassnahmen gegenübersehen. Angesichts dieser Dynamik drängt sich die Frage geradezu auf: "Wer sollte dringend über die Einführung eines Zero-Trust-Frameworks nachdenken?" Denn in bestimmten Szenarien ist die Einführung dieses zukunftsorientierten Security-Modells weniger eine Option als vielmehr ein Muss.
  2. Eine Frage der Compliance-Pflicht: Wenn Ihr Unternehmen vertrauliche Daten wie Finanzunterlagen, Gesundheitsinformationen oder personenbezogene Daten (PII) verarbeitet, speichert oder überträgt, müssen Sie in aller Regel Compliance-Vorschriften wie DSGVO, HIPAA oder PCI DSS einhalten. Mit den detaillierten Kontrolle des Datenzugriffs und der kontinuierlichen Überwachung durch das Zero-Trust-Framework ist es leichter, diese strengen Standards einzuhalten. Dadurch verringert sich auch das Risiko für unnötige Bussgelder, die mit der Nichteinhaltung verbunden sind.
  3. Verteilte Belegschaft: zentralisierten Belegschaften, die an einen einzigen Standort gebunden sind, werden immer seltener. Mit dem Trend zur Remote-Arbeit greifen die Beschäftigten von den verschiedensten Standorten aus auf Unternehmensressourcen zu, oft über private Geräte. Dies stellt die traditionellen Sicherheitsmodelle vor enorme Schwierigkeiten, da sie nicht für solch komplexe Anforderungen ausgelegt sind. Durch die Implementierung eines Zero-Trust-Frameworks ist sichergestellt, dass jeder Touchpoint in dieser vielfältigen Landschaft authentifiziert und kontinuierlich überwacht wird. Dies reduziert das Risiko für Sicherheitsverletzungen signifikant.
  4. Komplexe Cloud-Umgebungen: Nutzen Sie bereits eine Multi-Cloud- oder Hybrid-Cloud-Infrastruktur, dann kennen Sie die immensen Vorteile und sind sich der damit verbundenen Sicherheitsherausforderungen bewusst. Ein einziger Fehler bei der Zugriffskontrolle kann Ihr gesamtes System anfällig machen. Komplexe Umgebungen brauchen robuste Zugriffskontrollen, die sich an die Nuancen komplexer Cloud-Ökosysteme anpassen können. Diese bietet das Zero-Trust-Framework mit seinem Ansatz „Nie vertrauen, immer überprüfen“.
  5. Hochwertiges geistiges Eigentum: Wer mit proprietären Informationen oder geistigem Eigentum wie Patenten, Designs oder Softwarecodes arbeitet, habt im Falle einer Sicherheitsverletzung sogar noch mehr zu verlieren. Zero Trust sichert Ihre wertvollsten Assets durch Mikrosegmentierung des Zugriffs und die Durchsetzung der Multi-Faktor-Authentifizierung. Damit sichergestellt ist, dass nur autorisierte Personen Zugriff auf hochsensible Informationen haben.
  6. Dynamische Geschäftspartnerschaften: Wer auf die Zusammenarbeit mit Dritten wie Anbietern, Zulieferern oder Freiberuflern angewiesen ist, für den vervielfachen sich die Sicherheitsrisiken. Jeder externe Eintrittspunkt in Ihr Netzwerk könnte potenziell ausgenutzt werden. Das Zero-Trust-Framework minimiert dieses Risiko, indem es strenge Zugriffskontrollen auch für Drittbenutzer durchsetzt und so Ihre Gefährdung durch potenzielle externe Bedrohungen begrenzt.

Warum Unternehmen eine Zero-Trust-Architektur brauchen

Most organizations would benefit from using a zero trust architecture, but your company or organization should more seriously consider zero trust if some of the following scenarios apply to them.

  • Hybrid data management. If you use a multi-cloud, hybrid, or multi-identity system, you need a zero trust architecture to protect your internet-dependent data. The more access control you have over cloud and container systems, the better.
  • Industry compliance. If your business could be completely ruined by failing to follow compliance protocol, a zero trust model can help reduce that risk to your business.
  • Remote work environments. If you have a distributed workforce, your employees need the structure of a zero trust system to prevent data breaches that happen outside of a stationary office.

Key Components of a Zero Trust Architecture

There are three zero trust principles that make this type of architecture successful, which are user authentication, device authentication, and trust. At the very least, a reliable zero trust architecture should have the following components to ensure that those three elements are implemented.

  • Identity management. To have a reliable monitoring system, all devices, applications, endpoints, and users need to be identifiable with a strong authentication process.
  • Manage data. Organizing or classifying data is the first step to protecting data, along with data encryption and other security measures.
  • Device, network, and endpoint visibility. All endpoints must be carefully monitored, especially when granting (or denying) access to a network.
  • Analytics. The more you can document patterns and understand the behavior of users, the safer a company can behave.
  • Automation and other tools. When specialists can hand off security monitoring to advanced and trustworthy automation systems (and other similar tools), the faster and more accurate threats tend to be handled.

The Benefits of Choosing Zero Trust Architecture

Remember: this type of security is meant to reduce business and organizational risk, grant organizations better visibility and control, and ultimately prevent data breaches that otherwise interfere with your business initiatives. More specifically, a zero trust model provides benefits like:

  • Protecting identifiable personal information
  • Protecting intellectual property
  • Protecting financial information
  • Improving connectivity without putting data at risk
  • Reinforcing safe data and device use among employees
  • Having proactive tools that manage threats when they do arise
  • Enjoying better network performance and troubleshooting
  • Using simplified but advanced logging and monitoring tools
  • Having faster breach detection and response times
