5 Powerful Tips for Securing Cloud Infrastructure and Data

Securing Cloud Infrastructure is Critical

Cloud security is becoming a top priority for many organizations. While the cloud offers many benefits, it also introduces additional security risks. We will discuss below 5 tips for securing your cloud infrastructure.


There is good reason for writing about these 5 tips, as there are a growing number of threats and risks associated with cloud infrastructure and environments. Obviously, there are more steps you can take to safeguard your cloud infrastructure, but these five tips will get you a lot of bang for your money. 


Here are just a few of the threats and risks you need to be concerned about:

  1. Misconfigurations of cloud security settings
  2. cloud data breaches
  3. Unauthorized Access to cloud environment and assets
  4. Insecure Interfaces/APIs
  5. Lack of Visibility into cloud activities
  6. External Sharing of Data.
  7. Malicious Insiders accessing and misusing cloud assets.
  8. Cyberattacks on cloud environment


This is not an exhaustive list of threats and risks for cloud infrastructure and environments, but it covers many of the most common we are seeing out there. With all this risk, it is important to take the steps necessary to protect your environment and your organization’s data, both at rest and in transit. It is difficult to do, but it is achievable with the right people, processes, and controls.


By following these tips, you are on your way to keeping your data safe and protect your business from cyber-attacks.


Here are five tips to better secure your cloud infrastructure:

  1. Understand the shared responsibility model
  2. Implement access controls & restrict access to sensitive data
  3. Use encryption to protect your data
  4. Ensure endpoint protection is in place and relevant
  5. Maintaining logs and monitoring round the clock


Understand the shared responsibility model

The shared responsibility model is a critical concept to understand when securing your cloud infrastructure. The model divides security responsibilities between the cloud provider and the customer. Your cloud provider is responsible for securing the underlying infrastructure, while the customer is responsible for securing their own data.By understanding the shared responsibility model, you can better protect your data and keep your business safe from cyber attacks.


Cloud providers often having variations of the shared responsibility model and typically offer a wide range of security features, so it is important to familiarize yourself with their approach and then configure wisely. You need to make sure that your organization’s employees are aware of the security risks associated with using the cloud and take appropriate steps to protect their data. With a good understanding of the shared responsibility model and the right security measures in place, you have taken a strong step in the right direction in ensuring that your cloud infrastructure is safer and more secure.


Implement access controls & restrict access to sensitive data

When it comes to cloud security, one of the most important things you can do is implement proper access controls and processes. If your cloud providers offer best practices for implementing and utilizing their security features, then it is important to make sure that you are taking advantage of these practices and staying up to date on any future updates of these practices.


One of the biggest security issues for many cloud environments is misconfiguration. So, you need to have strong configuration and change control processes in place. Also, you need proper security and access controls to ensure that all the data, but especially sensitive data is protected.


Then test and verify these features, controls and processes periodically to ensure the data is protected.


One of the biggest dangers when using the cloud is granting too much access to sensitive data. If you are not careful, you can easily give away too much information and put your business at risk. It is important to restrict access to sensitive data as much as possible and ensure that only authorized users have access to this information.


Employees and contractors move into different roles and come and go from the organization, so it is important to limit their access to the least privilege, so they have just enough access to do their job. This way if there was an insider threat or someone from the access is able to gain control of an authorized users’ account, the bad actors are limited in their access and their ability to move east and west in the environment and accessing other sensitive data.


Use encryption to protect your data

The cloud is a great place to store data, but with the increasing sophistication and number of cloud-based threats, you should encrypt your data as well. Cloud providers offer a variety of encryption options; therefore, it is essential to comprehend the available options and configure the encryption settings appropriately. 


Encryption is one of the most effective methods for protecting cloud-based data. It helps ensure that, in the event of a data breach or unauthorized access to your data, it would be unreadable without the correct decryption key. Frequently, cloud service providers include encryption capabilities, or you can use third-party encryption tools. It is essential to use a robust encryption algorithm and a lengthy password or key to protect your data.


By using encryption, you can rest assured that your data is protected from most of the threats posed by the cloud. While no security measure is 100%, encryption can help reduce the risk of a data breach and keep your data safe from unauthorized access.


Ensure endpoint protection is in place and relevant

Endpoint security solutions, whether cloud-based or not are an important part of protecting your devices and data when working in or accessing data in the cloud. By using endpoint security, you can help protect your devices from malware and other threats, as well as ensure that your data is safe when it is being transmitted to and from your devices. Endpoint security can also help protect your devices while they are connected to the network and accessing data on-premise, helping to keep your data that may be transmitted to the cloud accurate and secure.


End-point security should be in place on for all users and on all devices that are used to access the cloud infrastructure and/or data. By using proper endpoint security measures, you can help protect your cloud infrastructure and data while using the cloud.


Maintaining logs and monitoring round the clock

It is important to maintain logs and monitor your cloud infrastructure around the clock in order to detect and respond to any malicious activity or threats as quickly as possible. By having an up-to-date log of all activity in your cloud environment, you can more easily track down and investigate any suspicious behavior. Additionally, by monitoring your cloud infrastructure constantly, you can quickly identify and address any issues that may arise. This helps ensure the security and stability of your cloud environment and protects your data from potential threats.


Another important reason for monitor your cloud infrastructure around the clock is it will help you detect any unusual activity or suspicious behavior. By monitoring your infrastructure this closely, you can quickly address any potential security threats before they become an incident.


In Summary

Cloud security is a complex issue that requires a dedicated and comprehensive approach in order to be effective. Implementing the appropriate security measures, such as those mentioned in the tips above are essential in protecting your cloud infrastructure and data from cyber-attacks.
