What Are the Fundamentals of Multi-cloud Security?

As people transition to the cloud due to its many benefits, the security of the data can become a real problem. Having a single security definition is not enough anymore. People require stronger and more agile security implementations. If you are someone whose business depends on data distributed along with multiple clouds, then multi-cloud security is something that you should be aware of. Of course, having more than one cloud system does have its benefits, but the challenges themselves are rather steep. Additional security is required to handle multiple requests of the data sending and receiving when dealing with multi-cloud security.

Challenges Persisted by Cloud Computing

Although multi-cloud intervention is a great thing to have for multiple people to use, it must be made sure that all the data that resides within the cloud is kept safe. These multi-cloud vendors have to secure your data in transit or at rest and make sure that your network, storage and basic computing needs are also free from vulnerabilities.

But wait a minute, there is more to it than meets the eye when it comes to securing all these assets. Users have a shared responsibility model with their cloud vendor, which means that the cloud vendors are not entirely in charge of securing your data if there are going to be some inconsistencies from your side. It could be providing access to the wrong people, choosing weaker passwords or not caring about specific security rules; in that case, the cloud vendor can't do anything.

This division of responsibility is known as the shared responsibility model with the user and the cloud vendor at different ends. Both need to work together if the security is to be guarded. The following are some more points regarding the shared responsibility model:

  • Traditional issues that come with cybersecurity need to be dealt with along with those who affect the workloads within the cloud.
  • Some broad items such as social engineering, application security, incident detection and vulnerability management are the broad categories that are included in it.
  • At times, some new challenges might surface with the cloud platforms; these might include a lack of visibility into some of the security events that happen within the cloud. Other than that, quick changes to the infrastructure and newer threats that might target these cloud services are also included in it.

The fundamentals of network security also need to be implemented at the same time as multi-cloud security. It will singlehandedly provide the best protection and security to all the data and information that already exists or is being shared continuously to these cloud services.

If you are interested in keeping your every transaction fully secure with multiple cloud systems, then you have come to the right place. The following are some of the best security fundamentals that you need to know or practice if you have a multi-cloud approach:


Identity is the first fundamental in guarding your assets, which is data when it comes to the multi-cloud approach. Suppose that a hacker can have the root access and makes himself the admin; you can only dream of all the havoc caused by this. That person will have access to all the files stored onto these shared cloud systems. Additionally, user accounts and other corporate information will also not be that far away from the attacker. This becomes an intermittent security threat—one that needs to be dealt with on a priority basis.

In order to secure your identity or user identity, you must preach a strong password adoption policy. It involves choosing a complicated enough password known to the user or otherwise can't be cracked using any dedicated form of attack, such as the dictionary attack, which guesses the password over various tries. Most users pick something easy to guess or even break, and that is where the problem lies. Even if they choose a more diverse and complex password, they will write it over something and forget all about it, only to be found by someone else, and the whole cycle repeats itself.

Issuing the multi-factor authentication can quickly take care of this issue. If you have enabled the multi-factor authentication system, then it means that you are using more than one way of authenticating yourself with the server. There is normally a password associated with another pin, but in most cases, using your phone number or email address as a source of authenticating can also be used in this regard. This way, it will become more difficult for hackers to crack. Another approach is having no password at all. Some strict security management for your privileged accounts can be employed to make sure that the hackers stay at bay at all times.


If there is a use case for protecting your identity in the first place or it is used as the fundamental of multi-cloud systems, it would have to be to protect the data. When a hacker gains access to your login information or your identity, the next thing they will do is scour your account or server system for possible data. It can be your data, financial data or some other corporate information. Still, the problem is they are after data, because it is the only thing that is of any use to them once they have breached the security of your account on multi-cloud systems.

Therefore, the need to secure it is imminent. The intensity to do so strengthens when we are talking about the multi-cloud systems, because the data is likely to travel here and there and remain in transit more often than it has to. That is why it should be encrypted at all times, not only in transit but also in rest. Encrypting it is the best way of securing the data. On the other hand, if an attacker or hacker gets their hands on it, then they won't be able to read it because it is encrypted into hashes ad symbols that otherwise can't be decrypted that quickly and not in the allotted time frame that the attacker will have when they have breached the security of the cloud.

So, even if they have penetrated the cloud systems' security, they will have a hard time getting around the encryption protocols that you have set. Encrypt all of your data, the one that is in transit and the one that is at rest, traveling through the email system or simply living in the memory of the cloud. This is the first line of defense adopted by the cloud security experts, knowing that it can help them secure the data that the cloud carries.


Among the list of security fundamentals for multi-cloud systems, the infrastructure security is well placed and a crucial factor to consider. You want to make sure that anyone who resides outside of your network or cloud architecture must not penetrate the firewalls and other security elements placed to restrict unauthorized entry, which can be done by strengthening your cloud infrastructure.

Adding passwords and more methods for identifying the users' authenticity are the first steps. Bringing encryption to the board is an improvement, but other things should also be considered and brought to the spotlight when trying to manage the cloud's infrastructure. Adding in firewalls to the network and the server where all the critical data and user account information is stored is surely a big leap in this stead, this way you will be strengthening not only the overall security of your cloud systems but making sure that hackers conveniently have a more challenging time getting around all the security implementations. Adding anti-virus and anti-malware systems would do the same for you, which is to add weight and protection to your overall cloud intensive infrastructure.


Automation is the key to the digital future. If something can be automated, and the manual input can be put to some other and more productive use, it should be done right away, which is what automation is all about. But as innovative and convenient, it may sound a lot of thinking that needs to be allocated to this approach to make it work. First, you must understand your company's working areas to the multi-cloud systems, which area does what, and how efficient or essential it is. Only when you have this information should you continue with integrating automation to various sites in your multi-cloud network.

This way, you will have a more direct understanding, such as which sites would work well with automation and which sites don't require its services just yet. Remember, it is not recommended to stick automation everywhere, even to the places where it doesn’t even belong. All it takes is a single server to glitch or cause the problem, and your whole multi-cloud system could go down. That is why you must practice caution when moving forward with this approach. Another thing can be done here: You can implement a professional to take care of the automated systems, such as reviewing the code from time to time and providing it with sudden inputs when required.

There are companies who practice automation to its breaking point, which means more often, and there are others who try their best to keep it to a bare minimum. It depends on your requirements and the type of infrastructure you have to work with at the end of the day. As illustrated earlier, make sure to add some manual gates and checks to review the process of automation from time to time. It would definitely help you catch any problems with automation and take care of any other elements before things start to get a little out of hand. This way, your data and all other digital assets remain secure.


Talking about a multi-cloud system, you are probably thinking about tons of data roaming around, some of it being in transit while the other at rest or in the cloud's memory. The point here is that you should exercise some standardization and try to bring it into the cloud platform itself. This can be done by analyzing and ingesting any logs that the data has left behind, changing cloud spaces from time to time. Analytics can help you with it. You need a good enough system in which such massive data can be fed and insights can be drawn.

These insights could point in several directions, such as improving the overall definition of security, adding more check and balance systems, improving cloud functionality, encrypting data or stabilizing the whole system even under heavy load. Analysis of the data that is stored within the cloud must be done from time to time; not only will it reveal the current state of the cloud but it also helps you make certain changes to improve the efficiency of the cloud systems.
