Understanding your cloud environment will enable you to develop a strong Cloud Security Strategy and ensure your organization’s data is protected from cyber threats.
1. Understand the Different Cloud Service Models
Cloud services can be classified into three categories: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS).
SaaS offers software applications over the internet, PaaS provides a platform for developing, testing, and deploying applications in the cloud, and IaaS offers virtualized computing resources like servers, storage, and networking.
Understanding these different cloud service providers’ models will help you select the one that best suits your business’s needs.
2. Know Your Cloud Deployment Models
Cloud deployment models refer to where the cloud services are hosted, the ownership structure, and the customer’s level of control over the infrastructure.
The four main deployment models are Public Cloud, Private Cloud, Hybrid Cloud, and Multi-Cloud.
A public cloud is owned and operated by a third-party service provider and made available to the general public.
On the other hand, a private cloud is a single-tenant environment, providing more control and security over the infrastructure.
Hybrid Cloud combines public and private clouds, while multi-cloud combines any two or more cloud deployment models.
Knowing these deployment models will help you determine the best approach for sourcing your cloud services.
3. Understand Your Cloud Architecture
Cloud architecture illustrates how all cloud infrastructure components are connected and interact.
It consists of several layers, including the physical infrastructure, the virtualization layer, the cloud platform, the application layer, and the user interface layer.
Understanding the architecture of your cloud environment will help you identify potential areas of improvement and streamline cloud operations.

Adopting a robust and comprehensive cloud security strategy will help you protect your data and significantly reduce the risk of cybersecurity threats.
Set up access controls in your Cloud Security Strategy
Securing your cloud infrastructure is critical to protecting your digital assets. One key step in developing a robust cloud security strategy is the implementation of access controls.
By restricting access to authorized personnel or processes, you can prevent unauthorized access, limit the scope of a potential security breach, and reduce the impact of an attack.
Access controls are necessary for securing your cloud-based applications and data, whether you’re using Infrastructure-as-a-Service, Platform-as-a-Service, or Software-as-a-Service.
Don’t wait until a breach occurs to take action. Make access control a foundational element of your cloud security strategy today.
1. Defining Access Controls
Before diving into how access controls work, defining what we mean by access controls is essential. Access controls are security measures to restrict access to specific data, systems, applications, or networks.
These measures ensure that only authorized individuals can access sensitive data or carry out specific functions within a system.
Access controls can be physical, such as security gates or fingerprints, or logical, such as usernames, passwords, or other authentication methods.
2. How Access Controls Work
Access controls work by assigning specific roles or permissions to individuals’ identities, such as a username and password, and only granting access to specifically authorized personnel based on these roles.
A role is a predefined set of permissions that an individual can use to access specific resources, perform specific tasks, or have specific privileges. Access controls can be applied to cloud storage or applications to ensure that only authorized individuals can access data.
Data sensitivity can be categorized based on public, confidential, or top-secret labels, which is an additional layer of data security.
3. Types of Access Controls
There are several types of access controls to consider when developing your cloud security strategy. The three primary types are mandatory, discretionary, and role-based access controls.
Mandatory controls are typically used in government agencies and other sensitive situations. They are designed to prevent people with different levels of security clearance from accessing data or resources that are above their clearance level.
Discretionary controls are used to grant or deny access to specific resources based on individual privileges.
Lastly, role-based access controls are used to grant or deny access to resources based on job roles, which provides a more streamlined way of managing access control.
4. Benefits of Access Controls
When implementing access controls, you ensure only authorized individuals can access sensitive data or system resources. This ensures you are protected from the threat of unauthorized access, which can result in data breaches, loss of confidential information, and unauthorized system access.
It also protects from other security threats, such as viruses, malware, and cyber threats.
Access controls help you maintain better control over your system and data, enabling you to track and monitor user activity and provide accountability for employees.
Invest in robust security solutions
Ensuring that your cloud security strategy is rock-solid is paramount in today’s digital age. Cyber threats are becoming more sophisticated and dangerous by the day, and investing in robust security solutions is the only way to stay ahead of the curve.
With cloud storage becoming increasingly popular with businesses of all sizes, the importance of solid security options in the cloud cannot be overstated.

Investing in security shows your clients, partners, and employees that you are serious about your business and data security. It sends a strong message that you value privacy and are committed to protecting sensitive information. This can help to build trust and credibility with customers, giving them confidence that they can trust you to keep their information safe.
Develop a disaster recovery plan
The final step in developing a comprehensive cloud security strategy is to have a disaster recovery plan.
It is necessary to have a plan that outlines what to do in the event of a data breach, disaster, or other security threats.
Your disaster recovery plan should include backup procedures, recovery actions, and preventive steps to minimize the impact of a security breach.
1. Identify the Critical Assets and Evaluate the Risks
The first step in creating a disaster recovery plan is identifying the company’s critical assets that need protection. This can include data, servers, applications, network infrastructure, and software.
Once these assets are identified, evaluate the risks associated with their failure, disruption, or data loss. This analysis will help you prioritize which assets are most crucial for the business and should be given priority in the recovery plan.
2. Define the Recovery Objectives and Strategies
After identifying the risks and prioritizing the assets for recovery, the next step is determining recovery objectives and strategies.
This involves defining recovery time objectives (RTO), recovery point objectives (RPO), and restoration strategies. RTO is the maximum time permissible for returning systems to operational normalcy, while RPO is the maximum acceptable quantity of data loss.
These objectives should be aligned with the business needs and regulatory requirements. Restoration strategies can be automated, manual, or a combination of both and should factor in the cost-benefit and practicality of the recovery.
3. Set up the Recovery Team and Communication Plan
With the strategy defined, the next step is setting up the disaster recovery team with clear roles and responsibilities.
The team should comprise IT personnel, business continuity managers, and executives with the authority to make decisions.
A communication plan should be established, specifying how the DRP is activated and who should be informed in case of an incident.
4. Regularly Test and Update your DRP
Testing the DRP is crucial to ensure its effectiveness and identify areas of improvement. Conduct regular drills to test the restoration time and recovery accuracy.
Regular updates are essential to ensure the DRP is up-to-date and compliant with evolving business needs, technology, and industry changes.
