The cons of using a hybrid cloud and CARTA

Hybrid cloud network services can act as a strong ally when the IT managers have issues related to information confidentiality, service quality, and the enterprise system performance that the enterprise will have after migrating to the cloud.

If the option for migration is the hybrid cloud, then it is essential to know its cons:

Difficult in implementing

It can, at times, be tough to implement and hard to maintain the hybrid cloud. When it comes to setting up a private cloud, it can be a project that is remarkably hard in itself because you require a demand that is high for local infrastructures like storage, servers, and the capabilities of the network.

In house expenses

It tends to have the disadvantage of being very expensive if you compare it to the public cloud. The cost that you will have to undergo during the maintenance and installation of servers is very high.

Concerns regarding security because of involving the third party

Because the hybrid cloud combines both the private and the public cloud, there tends to be no risk of intrusion of neighbors on the public cloud. Still, there is a tendency for infrastructure misuse contracted by another company, which can place your company under the risk of an attack from the main server, which then ends up the client’s systems' opening breach.





Data integration and compatibility

Compatibility, which is between files reused in the public and private cloud, can be a headache when utilizing the hybrid cloud. If that is the strategy you are trying to plot, ensure to have the software in place that will be able to run a variety of files on both platform and, for security purposes, convert files.

Because private and public clouds have fundamental differences, you have to know if they are compatible or not. It can be the difference between failure and success of your business. Both applications and data in a hybrid cloud are available in a symbiotic relationship, denoting that one will be useless unless it is with the other one.

Therefore, when you are considering where you will store each of the applications or data, it is essential to find out how the integration will be done.

Visibility

With your information and resources placed on the public and private based cloud networks, you might end up losing sight of the full view of the other information. It might become very complicated, especially if you are utilizing several third-party cloud services providers.

Should we use Continuous Adaptive Risk and Trust Assessment in a hybrid cloud environment?

Continuous Adaptive Risk and Trust Assessment (CARTA) is a strategic approach to IT security that aims to provide continuous and contextual evaluation of risk and trust for users, devices, applications and data in a dynamic IT environment. CARTA was introduced by Gartner in 2010 as an evolution of its Adaptive Security Architecture .

Continuous Adaptive Risk and Trust Assessment has many benefits for IT security, such as enabling faster detection and response to threats, reducing the attack surface, enhancing user experience and supporting digital transformation. However, CARTA also has some disadvantages, especially when applied to a hybrid cloud environment, which combines on-premises and cloud-based resources.

Some of the disadvantages of CARTA in a hybrid cloud environment are:

- Adaptability: Adapting to the changing risk and trust levels in the hybrid cloud environment can be demanding, as it requires constant updating and fine-tuning of security rules, thresholds and actions. This can also introduce latency or performance issues, as well as potential conflicts or trade-offs between security and functionality .

- Complexity: Implementing CARTA requires a high level of integration and coordination among various security tools, processes and policies across the hybrid cloud environment. This can increase the complexity and cost of security management, as well as the risk of configuration errors or inconsistencies .

- Trust: Establishing and maintaining trust among different entities in the hybrid cloud environment can be difficult, as there may be conflicting or incompatible trust models, policies or mechanisms. For example, some cloud providers may not allow customers to verify or modify their security settings, or may not disclose their security incidents or vulnerabilities .

- Visibility: Achieving full visibility and control over the hybrid cloud environment can be challenging, as different cloud providers may have different security standards, protocols and interfaces. Moreover, some cloud services may not support the level of monitoring and auditing required by CARTA .

In conclusion, Continuous Adaptive Risk and Trust Assessment is a promising approach to IT security that can help organizations cope with the challenges and opportunities of the digital age. However, CARTA also has some drawbacks, especially when applied to a hybrid cloud environment, which requires careful planning, implementation and evaluation to ensure its effectiveness and efficiency.
