Best Practices zur Entwicklung einer Hybrid Cloud-Sicherheitsstrategie
Cloud sprawl is an inevitable challenge as your organization shifts workloads from on-prem data centers to multiple public, private and hybrid cloud platforms. The traditional security perimeter blurs, creating complex environments that demand a new approach to protection.
To secure this hybrid-cloud reality, you must shift security controls left, adopt modern tools and ground strategies around core cloud security principles that lead to hybrid-cloud exposure management.
Hybrid-cloud exposure management gives you a comprehensive view of your cloud attack surface. By combining public cloud, private cloud and on-prem resources, hybrid-cloud models introduce greater agility and increase the potential for cyber risk. Exposure management helps by contextualizing security findings so you can prioritize remediation based on your unique policies, business needs and risk tolerance.
Exposure management normalizes how you identify and manage risk across different environments. It eliminates security blindspots and strengthens defenses against attackers’ lateral movement.

7 steps to harden cloud security posture
Cloud breaches are alarmingly common, even as your organization invests heavily in threat detection and response tools. The root cause of most of these breaches isn’t sophisticated attacks. It’s poor cloud hygiene. Simple misconfigurations, vulnerabilities or excess privileges can create undetected and unremediated exposures that leave your organization vulnerable.
Three core challenges drive this trend: speed, scale, and skills shortages.
The pace of cloud adoption is relentless, with cloud-first organizations seeing developer-to-security ratios as high as 100:1.
Meanwhile, the complexity of cloud-native architectures — microservices, containers, Kubernetes and infrastructure as code (IaC) — magnify the risk. A single misstep can replicate across environments at scale. Adding to the burden, every cloud platform has its own security tools, best practices and skill requirements, further stretching already overwhelmed security teams.
Exposure management is critical to overcoming these challenges. By focusing on proactive identification, prioritization and remediation of cloud risks, you can shift from reacting to breaches to preventing them altogether.
In this white paper, you’ll learn:
- Einen pragmatischer Ansatz zur Industrialisierung von Cloud-Sicherheit und zur Prävention von Sicherheitsverletzungen
- Insights into high-profile breaches — and how they could have been prevented
- How to navigate the security-tool acronym soup and choose what to adopt and when
- Wichtige Indikatoren und Überlegungen zur Messung des Erfolgs Ihres Sicherheitsprogramms

Häufig gestellte Fragen zu Cloud-Sicherheit
Haben Sie Fragen zu Cloud-Sicherheit? Hier finden Sie einige häufig gestellte Fragen und dazugehörige Antworten:
Was ist Cloud-Sicherheit?
Welche Sicherheitsrisiken bestehen im Cloud Computing-Bereich?
While cloud computing offers your organization great flexibility and scalability, it also has a number of security risks. Any time you move your data and workloads off-premises, you lose some control.
For example, Amazon Web Services (AWS) has a shared responsibility model. That means AWS is responsible for physical security of the cloud, but you are responsible for your data and workloads.
Ferner aggregieren die meisten Cloud-Provider Daten und Services in ihren Systemen, wodurch Angreifer häufig mit weniger Aufwand auf mehr Daten zugreifen können. Dies wiederum bedeutet, dass Cloud-Umgebungen den Wert eines Hacking-Ziels erhöhen können.
Other potential risks include:
- Blind spots in your cloud environment
- Not meeting legal requirements or compliance obligations
- Losing service if your cloud provider goes down or you lose connectivity to your cloud
- Unauthorized access to your data by your cloud provider’s employees
- The potential that you could lose your data stored in the cloud
Warum ist Cloud-Sicherheit wichtig?
Cloud security ensures your data, business workloads, and apps remain safe while stored off-site within a cloud infrastructure.
Auch wenn die meisten Cloud-Provider ein weit höheres Maß an Sicherheit bieten als viele On-Premises-Lösungen, trägt die kontinuierliche Erfassung und Bewertung Ihrer Cloud-Assets dazu bei, die Sicherheit Ihrer in der Cloud gespeicherten Informationen weiter zu erhöhen.
Whether you’re a business facilitating cloud workloads or an individual needing extra storage for your files, cloud security can help ensure all of your data remains secure.
Was sind Cloud-Angriffe?
Die Cloud ist ein potenzieller Angriffsvektor, über den Hacker Schwachstellen ausnutzen und Ihr Unternehmen gefährden können.
Attackers can attempt to exploit your cloud environments in several ways. For example, an attacker can inject malware to access information stored in the cloud and, once inside, move laterally to affect other systems. Denial-of-Service- (DoS) oder Brute-Force-Angriffe, Wrapping-Angriffe, Service-Hijacking, Man-in-the-Middle-Angriffe, Angriffe durch Insider und Seitenkanalangriffe sind weitere Arten von Cloud-Angriffen.
