Cloud Cybersecurity Basics

 

There are a number of security issues that affect cloud computing. For example, third-party storage, internet access, and data center hardware are all vulnerable to hacking and other security threats. Additionally, power outages can affect data centers and permanently wipe out data. A recent power outage at Amazon's cloud data facility resulted in hardware damage. In short, cloud cybersecurity can be a daunting task. However, by following some simple rules, cloud users can protect their data and minimize the risk to their business.

Shared responsibility model

While the shared responsibility model in cloud security places some of the security responsibilities on the provider, it also places a significant amount of responsibility on the users. Users must ensure that the security of their data, applications, and user devices is maintained throughout the application lifecycle. To do this, users need to install appropriate security tools and use proper encryption. They must also maintain proper identity management and access management, and secure their integrations with the cloud provider.

The shared responsibility model for cloud cybersecurity requires clear communication between the customer and the cloud provider. The customer and the CSP must identify and address the security risks to cloud data and infrastructure. Any agreement should also clearly define the responsibility for security and any remediation necessary if an incident occurs. Further, the customer must be aware of how much responsibility he or she bears for cloud infrastructure and applications. A shared responsibility model is beneficial for organisations that have both a limited security budget and a limited amount of IT staff.

Segmentation of services

In a fluid environment, the concept of cloud segmentation makes sense. It helps to create an application-based approach to cybersecurity. Instead of developing applications and sending them to security for review, developers can focus on business agility and application development. This approach preserves agility and business value and ensures that cloud security policies are aligned with the business strategy. Moreover, developers can focus on product development and application delivery, without compromising security.

Micro-segmentation is another way to achieve security objectives. This approach detaches segmentation from the network and enables organizations to define policies that apply across east-west communication. It can protect high-value applications, compliance mandates, and sensitive data. It works by applying granular policies across workloads. Micro-segmentation is an example of a highly effective application-centric approach to cybersecurity.

End-to-end encryption

While end-to-end encryption can reduce the risk of data breaches and protect your privacy, it is not sufficient in itself. End-to-end encryption is necessary when your information is being transmitted across an insecure network. Without it, unauthorized third parties could read your information and use it to target advertisements. Additionally, end-to-end encryption does not allow outside users to manipulate data before it is delivered. Without it, hackers and other malicious actors would not be able to access your private data, which is why end-to-end encryption is important.

The advantages of end-to-end encryption are numerous. It protects your data from hackers, but it also hinders the ability of law enforcement to use it. If your data is encrypted, the service provider's server would not be able to read it, and hackers could be unable to find any evidence based on the encrypted data. Furthermore, end-to-end encryption also prevents service providers from decrypting your data, which would be problematic if law enforcement wanted to find out if your information is secure.

Compliance with data protection laws

Complying with data protection laws is a necessity in some industries. GDPR has made compliance across the EU and EEA simple by establishing uniform data privacy rules across the member states. This extends to cloud infrastructure as well, which must conform to data protection laws and regulations. Non-compliance may lead to hefty fines, lawsuits, and the loss of customers. Here's how to ensure compliance with data protection laws when using cloud cybersecurity:

For the most part, compliance with data privacy laws requires a thorough understanding of how to protect the information collected by organizations and third parties. Organizations should also know what cloud services they use and review how data is transferred to them. The right level of protection is based on the sensitivity of the data, so organizations must consider the country of origin before placing it in the cloud. But while compliance isn't an exact science, it should be a top priority when using cloud cybersecurity.

Training for users

There are several different types of cloud security training available, ranging from general information to specific classes that target specific industries or solutions. The type of training you need depends on what you hope to accomplish with cloud cybersecurity. The most basic class will cover general cybersecurity issues, while more advanced courses will focus on specific topics such as virtualization, industrial control systems, or vendor-specific information. Training for cloud cybersecurity users is important no matter what your company's goals are.

If you are new to cloud security, you should consider a general cloud administration certification such as the CompTIA Cloud+. This certification covers a broad range of cloud security topics and is an excellent way to demonstrate that you understand the basics of protecting your cloud infrastructure. The Cloud+ certification is the successor to the CompTIA Cloud Essentials+ certification. The Cloud+ cert requires no formal prerequisites, but it is advised that you have at least two to three years of sysadmin experience.
