The migration of business operations to the cloud is advancing steadily, driven by the promise of agility and efficiency. However, this digital transformation process conceals cybersecurity risks that many organizations continue to underestimate, as industry experts warn.
Néstor Markowicz, COO of CertiSur, identifies a invisible risk main:believing that the cloud is, by definition, secure . According to him, this perception leads to the assumption that hiring a provider solves all security issues. Reality shows that the most frequent attack vectors do not come from the provider's infrastructure, but from failures in internal management.
Markowicz notes that the most frequent attack vectors come from misconfigurations, unmanaged access, or exposed credentials . In this context,a cloud is secure only if the company assumes its share of the commitment . The executive adds that the most common mistake is the false sense of complete protection that outsourcing the service generates.
Cloud security is governed by a shared responsibility model, where the provider manages the infrastructure, but the management of data, access, and configurations falls on the user company.
This model, while allowing companies to focus on their business, also creates gray areas . Markowicz warns:no one knows for certain who is responsible for a control, and that's where problems usually appear . For this reason, clear governance of roles and responsibilities becomes essential, especially in multicloud environments.
With the disappearance of the traditional security perimeter in the cloud, the Zero Trust (Zero Trust) approach consolidates as an effective strategy. This model is based on the principle of don't trust anyone and always verify.
Protecting the perimeter is no longer enough, because in the cloud the perimeter becomes blurred , Markowicz maintains. The Zero Trust model forces granular control of access, continuous monitoring of behaviors, and minimization of privileges . While the approach is technologically robust, its implementation requires a profound cultural change within organizations.
In this complex security scenario, digital certificates fulfill an essential function. Markowicz emphasizes that they are the piece that guarantees the authenticity of identities, the integrity of communications, and the encryption of data in transit and at rest . In essence, they are the component that makes a trusted cloud possible.
However, their management is one of the most common weak points. Maintaining an updated inventory of keys, certificates, and credentials is key to preventing vulnerabilities and avoiding service interruptions or breaches.
CertiSur's COO emphasizes that security is a process, not a product. There is no magic solution, but rather a comprehensive and sustained strategy over time.
To strengthen cloud security, Markowicz recommends:
-
Identity and access management with clear policies and multi-factor authentication.
-
Complete visibility over data, identities, and cryptographic assets.
-
Encryption of data in transit and at rest.
-
Continuous monitoring and periodic audits.
-
Implementation of Zero Trust.
