CASE STUDY

How we mitigated attacks and strengthened Cloud environment cybersecurity

After a cyberattack took one of its accounts offline, Monjuá needed expert, qualified support to quickly respond to virtual threats.

The company turned to UDS Cloud Consulting for assistance in resolving the issue and strengthening its long-term security posture.

Here’s how we transformed Monjuá. Keep reading.

UDS proposed the implementation of a zero trust approach. Our DevSecOps squad implemented measures such as Multi-Factor Authentication (MFA) and restrictive access policies, in addition to restructuring Monjuá’s private network architecture.

The result was a rapid recovery of control over the infrastructure and strengthened resilience against future attacks. We established a solid foundation for the company’s security and operations – all within just three days.

Here’s how we transformed Monjuá. Keep reading.

THE COMPANY

Monjuá

Founded in 1964 in Porto Alegre, Monjuá has established itself as one of the largest fashion retail chains in Rio Grande do Sul, with more than 70 physical stores in strategic cities across the state.

Over its nearly 60-year history, the company has become a reference in innovation, customer care, and commitment to its clients, employees, and partners.

Monjuá also works with high-recognition national and international brands, offering exclusive private-label products.

THE CHALLENGE

Restore cloud infrastructure security and create strong defenses against future attacks.

EXPERTISE

After the attack, the lack of an in-house cybersecurity team highlighted the complexity of regaining access and restoring operations.

Advanced technical knowledge was needed to manage the crisis and recover the infrastructure.

SECURITY

The attack revealed multiple areas for improvement, from configurations to security policies, to create a more secure and less vulnerable environment.

It was essential to establish guidelines that would make the infrastructure sustainable in the long term.

OPTIMIZATION

While Monjuá’s existing infrastructure was robust, it was not fully leveraging its potential. Configuration and resource management deficiencies affected overall security.

The goal was to ensure that Monjuá gained greater autonomy and extracted more value from AWS resources.

Brute-force attacks are mass attempts to discover passwords and credentials. Attackers use automation and hybrid techniques to identify weak combinations and gain unauthorized access to systems.

This incident underscores the importance of measures like strong password usage and limiting login attempts to protect against unauthorized access and ensure data security.

THE SOLUTIONS

UDS Cybersecurity experts developed an attack containment plan and security guidelines.

Specialist Squad

UDS deployed a team of highly specialized Cloud and Cybersecurity experts who conducted a detailed analysis and identified the source and extent of the attack.

Security Controls

We established zero trust policies, including the implementation of Multi-Factor Authentication (MFA) for all access points, granular permission policies, and network segmentation techniques.

Private Network

We developed a virtualized private network architecture, using micro-segmentation techniques to protect critical resources. The strategy included isolated subnets and strict access controls.

INSIDE THE SOLUTION

Container
Orchestration

Implementing a private network and container orchestration played a key role in the recovery and strengthening of Monjuá’s infrastructure.

Container orchestration facilitated the automated management of applications, enabling large-scale deployment efficiently and securely.

It also ensured application performance by maintaining their operation in a controlled and resilient environment.

Zero Trust

Zero Trust is a cybersecurity model that operates on the principle of “never trust, always verify.” Instead of assuming that everything inside an organization’s network is secure, this approach requires constant verification of all access requests.

Every user and device attempting to access system resources is treated as potentially hostile until their identity and integrity are verified.

The model employs technologies such as multi-factor authentication (MFA), encryption, and network segmentation to minimize attack surfaces.

For Monjuá, implementing Zero Trust meant fortifying their infrastructure against future attacks.

THE RESULT

Recovery of infrastructure and new security policies in just three days.

The implementation of a multi-layered security framework and adherence to zero trust practices ensured Monjuá’s resilience against future attacks.

Optimizing the existing infrastructure enhanced cloud operational performance, giving the company greater autonomy and control over its environment.

Knowledge transfer to Monjuá’s internal teams and the implementation of compliance practices also resulted in valuable know-how gains for the company.

Client satisfaction was high, with solutions that met their needs and provided direction for future implementations.
