Advanced Persistent Threats (APTs): Protect your organization with Cosmikal Endurance
4 de October de 2024Today’s organizations face the challenge of protecting their digital resources and assets from all kinds of threats. Remote work is increasingly common, and the boundaries between professional and personal life are blurring. This makes it more common for employees to use personal devices to access company assets. It’s as common as doing it from anywhere at the most unexpected time, far from the company’s data centers.
This adds an extra risk to the security policies of organizations, which, until a few years ago, based their entire strategy on limiting access to a connection, a location, or specific hours, setting permissions and restrictions according to user profiles, or acting retrospectively, based on recorded activity.

Change of model
The Zero Trust strategy is a network security model that originated in 2010 with a paradigm shift. That year, analyst John Kindervag proposed transforming the previously valid ‘trust and verify’ approach into ‘never trust, always verify.
This new approach assumes that no person or device, whether inside or outside the network, can be trusted by default to access information or operate within the system.
Instead of relying on a static network perimeter, the Zero Trust model is based on continuous verification of the identity and authorization of all users and devices attempting to access network resources, regardless of whether they are inside or outside the corporate network.
Components of a Zero Trust Architecture
A Zero Trust cybersecurity framework generally has the following common characteristics:
- Multifactor Authentication (MFA): requires multiple forms of identity verification from the user before granting access.
- Network Segmentation: divides the network into smaller, controlled segments to limit the spread of attacks.
- Microsegmentation: applies granular security policies at the application level to restrict access only to the necessary resources.
- Traffic Inspection: examines and validates all network traffic to detect and prevent threats.
- Continuous Monitoring: constantly monitors network and user activity to identify suspicious behaviors.
Thus, the Zero Trust architecture seeks to address common security challenges through proactive, rather than reactive, techniques. This model, also known as ‘perimeterless security,’ operates autonomously as an architecture. It is also present in network access (ZTNA) or gateways (SWG).

Advantages and Differentiating Values
It is evident to point out that the main advantage of a Zero Trust model is the improvement of security. This is actually due to a reduction in risk by operating on the principle of trusting no user or device by default.
A competitive advantage over other security strategies is that the attack surface is drastically reduced against any threat. Access controls are much stricter than in other models, the network is divided into very small segments, and specific, granular security policies are applied at a lower level. The combination of all these factors results in minimal exposure to potential threats.
Today, it’s not just individuals who access resources; applications and automations also need to connect to other assets to function. This forces the teams responsible for designing information technologies to rethink the access model so that all types of users, including third parties, can continue to access resources quickly and easily while ensuring security. The Zero Trust architecture addresses this need by providing detailed security and reducing access complexity.
Furthermore, a security policy based on Zero Trust architectures helps organizations comply with security and privacy regulations by ensuring strict control over access to sensitive resources and data.
How to Implement the Zero Trust Security Model
Before implementing a transformative model in the organization’s security policy, it is essential to study whether the new proposal aligns with its objectives. Therefore, it is advisable to follow this process when rethinking the advanced security policy in any company:
- Evaluate the Current Security Posture: Identify vulnerabilities and weak points in the existing security infrastructure.
- Design a Zero Trust Architecture: Develop a plan to implement stricter security controls and segment the network.
- Implement Security Controls: Deploy tools and technologies that support multifactor authentication, micro-segmentation, and traffic inspection.
- Education and Awareness: Train employees on security best practices and the importance of adhering to Zero Trust policies.
- Continuous Monitoring and Adjustment: Constantly monitor the network and adjust security policies as needed to adapt to new threats and changes in the environment.
Compliance with each of these phases requires the dedication of technical and human resources only achievable by a few. However, implementing a Zero Trust security architecture is simplified by choosing a solution like Cosmikal Endurance, a set of tools designed and integrated for the protection of digital assets of any type of organization, regardless of its size and scope.
Cosmikal Endurance is designed as an ecosystem that facilitates the transition to Zero Trust in an organic, transparent, and straightforward manner for the organization and all its users. It is developed to integrate with other tools or solutions already implemented in the company, which helps to streamline and adapt resources.
Used as a standalone solution or in combination with other resources, it provides a fully reliable security model tailored to the technical and human needs of organizations.

Is Zero Trust valid for everyone?
The Zero Trust model is highly beneficial for many organizations, but its implementation can be more challenging for some companies, especially those with older or less flexible network infrastructures. However, with proper planning and the selection of appropriate tools and technologies, most organizations can adopt a Zero Trust approach to improve their security posture.
Thus, Cosmikal Endurance provides the necessary technology to equip the organization with a preventive security architecture, as well as a method of implementation that simplifies the onboarding processes and user training, without affecting service continuity.
As a solution fully aligned with the Zero Trust model, Cosmikal Endurance enhances the organization’s resources and keeps threats much farther away.
