Protecting Data in Cloud: Is My Data Really Safe?

Cloud is Everywhere, but Are We Truly Secure?

While the cloud has become deeply integrated into our daily lives, many people do not fully understand the risks lurking behind its convenience. As more companies accelerate their cloud transformation, the vast majority of core data is being concentrated within cloud infrastructures. The problem is that the maturity of security systems is failing to keep pace with the speed of convenience, leading to a constant stream of data breaches.

What is the Cloud? Benefits and Risks

The cloud is a remote distributed system accessed via the internet. It reduces reliance on physical hardware and allows users to instantly utilize the storage and processing power of remote servers whenever needed. For businesses, the biggest draw is the shift from CapEx (purchasing expensive hardware upfront) to OpEx (subscription-based pricing), providing both scalability and availability.

Benefits of the Cloud

A well-designed cloud environment can offer higher security than on-premises infrastructure in several ways:

• Constant Monitoring: Major Cloud Service Providers (CSPs) like AWS and Microsoft Azure operate 24/7 monitoring systems to detect anomalies.

• Rapid Patching and Updates: Unlike on-premises environments where physical constraints often delay security patches, cloud infrastructure allows for immediate updates to respond swiftly to vulnerabilities.

• High Accessibility and Availability: Data can be accessed from anywhere with an internet connection. Multi-region structures ensure service continuity even if a specific data center fails.

• Cost Efficiency: Small and medium-sized enterprises (SMEs) can implement necessary security features easily without heavy initial investments in dedicated hardware or expert personnel.

Security Risks of the Cloud

To fully enjoy these benefits, strict principles must be followed from the design stage. In real-world operations, however, various factors expand the attack surface:

• Misconfiguration: One of the most common causes of cloud breaches. This issue becomes more frequent as multi-cloud environments grow in complexity.

• Account Takeover (ATO): Attackers steal legitimate user accounts through phishing, credential stuffing, or AiTM (Adversary-in-the-Middle) attacks. If an admin account is compromised, the damage scales exponentially.

• Supply Chain Compromise: Infiltrating through linked third-party paths rather than the cloud service itself. A breach of a single large vendor can cause a chain reaction affecting thousands of customers.

• DDoS Attacks: Paralyzing services with massive traffic. CSP-level defenses alone struggle to fully block Application Layer (L7) attacks.

• Insider Threats: Difficulty in controlling risks such as unrevoked access for former employees or intentional/unintentional leaks by employees with excessive permissions.

 

 

Recent Major Global Cloud & Data Breaches

Attackers target organizations regardless of size. In March 2026 alone, several significant cloud breaches occurred:

• Stryker (Massive Attack via Admin Account Takeover): On March 11, 2026, Stryker employees across 79 countries found their screens blank. The “Handala” hacking group allegedly exploited the Remote Wipe feature of Microsoft Intune to reset approximately 80,000 devices simultaneously. By stealing an admin account and creating a new global admin, they executed the attack without malware. This caused massive disruptions in manufacturing and shipping, and some employees lost personal data and authentication app info.

• European Commission (AWS Infrastructure Breach): The EU officially confirmed a cyberattack on its Europa.eu platform infrastructure running on AWS. While a spokesperson stated the attack was contained without impacting internal systems, reports suggest hundreds of gigabytes of data were leaked. This incident caused a significant stir as a core public institution’s cloud infrastructure was directly targeted.

Representative Cloud Security Solutions

These cases prove that cloud threats are a reality, not just a possibility. Even with robust native cloud security, breaches are likely without specialized solutions. This is especially true for startups and SMEs that lack dedicated security personnel.

To bridge this gap, SaaS-based security platforms have emerged. Cloudbric is a user-centric SaaS security platform designed for non-experts. It provides:

• Expert Support: Security professionals assist in applying basic policies while allowing flexible management through detailed options.

• Intuitive UI/UX: Allows those without technical expertise to navigate security settings easily.

• Real-time Monitoring: Enables a stable security environment even without a dedicated in-house team through rapid threat response.

In an era of increasingly sophisticated threats, adopting a professional security solution is no longer an option—it is a necessity.
