Tips to Build Cloud Security Architecture

The use of the cloud is increasing day by day. Several cloud application developers are involved in developing the applications specific software for different types of cloud platforms such as IaaS and PASS. However, security is an important factor for these platforms.
This platform provides security features including authentication, logging, and profile management. But still, the security issue is one of the major barriers to the adaption of cloud architecture by organizations and enterprises. Virtual machine configuration on the IaaS Platform should be performed in a secured manner. Managing the user privileges on the PaaS platform is another security concern in the cloud environment.
A major difference between public cloud and private cloud is that cloud security duties in a public cloud is shared between the cloud customer and the cloud service provider, whereas in cloud security, duties in a private cloud are managed by the customer.
Some Cloud service providers play a crucial role in securing the shared infrastructure including switches, routers, firewalls, load balancers, storage networks, hypervisors, management consoles, and cloud API.

Cloud Security Challenges

Building cloud security architecture is a challenging task. Organization’s security policies, some relevant compliance standards and the dynamic nature of cloud infrastructure are some important factors that need to be considered during the development of cloud security architecture.

Some of the major cloud security challenges are as follow –

1. Unsecured API

APIs play an important role in a cloud environment. If API is not secure and using a poor authentication mechanism then it becomes easy for attackers to access and gain control over the entire environment. So use secured API to build a secured cloud architecture system.

2. Misconfiguration

Cloud environments consist of several components and portable parts such as computing instances, a large number of buckets, databases, containers, and some server-less functions. If any of these components do not configure properly in a secure manner then it may allow attackers to access them through public networks and sometimes it may cause damage to the system and data.

3. Compliance Risk

Compliance risk should be handled properly by the cloud service provider. The customer should ensure that the cloud provider supports all-important compliance requirements and understand what controls and services as a customer, one can use to meet the compliance obligations.

4. Identity and access

Employees can create resources on the cloud easily and can also leave them unattended but cloud systems are not secured by default. Most of the cloud service provider also gives the service for managing the identity and access management capabilities. This is the responsibility of the organization to set them correctly and apply them consistently according to workload.

 

Vital Tips to Consider for Building Cloud Security Architecture

The first step before building the secure cloud architecture is that cloud architects should understand the capabilities offered by the different cloud platforms. Some important tips used to build secure architecture are given below:

1. Architect for security as service

Security automation for cloud system architecture covers several aspects such as virtual system configuration, provisioning of certificates, account-related privileges, and log configuration. Architect for security as service includes the security policies for firewall, key distribution. Testing of application should be migrated to a self-service model. This will eliminate the risk of human error and also improve operational efficiency.

2. Data Encryption

Due to the increasing use of the cloud, there is a possibility that the clouds which are private today may become a public cloud in the future. Cloud system architecture should support encryption methods to encrypt all sensitive data.

3. Conduct Due Diligence

It is important to note that before expanding a cloud deployment to additional cloud providers, organizations should carefully investigate the security and resilience properties of the cloud provider as a whole and the specific services they intend to use. The due diligence process should cover the following-

• To define the security and availability benchmarks there should be a study of data from organizations working in the same industry.
• Discovering the cloud provider’s security best practices and their impact on the organization is also an important factor to be considered.
• Customer should also understand that how the cloud service provider can help meet your compliance obligations and what are the standards of certification.
• Evaluate first-party security services and compare them to third-party alternatives.

4. Protect Cloud Endpoints

Endpoints of cloud architecture systems play an important that why many organizations are deploying multi-layer protection at the endpoints. Endpoints change from time to time on-premise and need a high level of security. End Points protection tools help the organization to control workload on their cloud. So endpoints must be secure.
Conclusion Your data can always remain safe if you make the right use of a cloud system rather than just having an on-premise storage system. All information, whether it is just about the products, or your customers or operation guidelines, the safety of it is very vital. Although, securing cloud architecture is not always a simple procedure. However, data integrity is very necessary, and having said so never has the mindset of just investing in securing the architecture once. Rather, it is better if you continue to do so repeatedly as per the latest technology.
