In this guide, we’ll cover some of the most typical security threats companies face throughout cloud migration in addition to finest practices you can follow to combat these hazards.
Is information in cloud migration secure?
According to the Flexera State of the Cloud Report 2022, public cloud adoption continues to speed up, with half of all research study respondents’ work and data residing in a public cloud. As an effect of this development, there are likewise growing issues about information security throughout cloud migration.
A few of these security issues consist of the following.
The application programming interfaces used to link cloud applications, information and infrastructure can be a significant source of vulnerability for cloud information security. APIs might have weak authentication and authorization controls, an absence of sandbox protection, and excessive opportunities. Organizations needs to thoroughly evaluate these vulnerabilities when moving information to the cloud.
Security blind spots
Must-read security protection
Cloud data can also be at danger since of security blind areas in the cloud facilities. Issues such as using software-as-a-service applications for sensitive data and developing shadow IT networks prevail in some cloud environments. Organizations needs to know these potential vulnerabilities when migrating to the cloud and take actions to alleviate them.
Lots of companies need to comply with regulatory requirements when moving information to the cloud. Security compliance requirements can be a substantial challenge for companies, particularly if the cloud service provider does not fulfill these requirements.
Lastly, migrating information to the cloud can increase the danger of data loss. This is particularly real if the cloud service provider does not have robust controls in location to secure and recuperate data in case of a security occurrence.
Tips for protecting information in cloud migrations
While there are lots of prospective security problems that can arise throughout a cloud migration, there are likewise several steps your team can require to better secure your applications and information. We advise the following 7 pointers to protect your company’s information during cloud migrations.
Understand your data
Business getting ready for a cloud migration need to make certain they have a precise understanding of their information and its requirements. That implies migration groups need to understand their information’s present and future use as well as storage and retention policies established by the company’s information governance framework.
Various cloud management tools are readily available to help with some of these data understanding and optimization jobs, consisting of information deduplication software. Securing cloud data starts with understanding what it consists of and how it will become used and/or disposed of.
Understand your data compliance requirements
In addition to understanding the data itself, organizations need to be aware of any compliance requirements that use to their datasets throughout cloud migrations.

For example, numerous business go through regulative structures such as GDPR, PCI-DSS and HIPAA, which include strict requirements for the stripping of personally recognizable details prior to data migration.
Organizations should ensure cloud infrastructure suppliers fulfill compliance requirements or carry out additional controls where required.
Protect your APIs
When moving information to the cloud, protecting the numerous APIs that control access to and between cloud applications and facilities is essential. For boosted API security, you can begin by using strong authentication and authorization controls, protecting APIs from destructive or automatic attacks, and eliminating excessive user gain access to opportunities.
Encrypt your data during transit
Transferring data in cloud migrations can create additional security vulnerabilities. One effective way to secure sensitive information is utilizing end-to-end file encryption.
This procedure is generally done utilizing an encryption protocol like Transportation Layer Security, which adds an extra layer of security by securing all information prior to it leaves the source system and decrypting it after it arrives in the location system. Numerous file encryption algorithms are offered to pick from depending on the quantity of protection you need, but many use modern industry standards like AES or RSA.

Companies ought to likewise make sure to firmly store any encryption keys and qualifications required for gain access to and make regular backups in case of data loss. Making use of a cloud company that provides integrated file encryption services can streamline this process. However, business must still conduct their due diligence to guarantee they have the correct tools and security steps before initiating the migration.
Restrict data gain access to during cloud migration
Restricting access to information during cloud migration is a vital action for companies looking for to transfer their information safely. You must take numerous actions to guarantee only designated users can access the information as essential. These actions include:
- Implementing and implementing user-level authentication and permission guidelines
- Setting up robust two-factor authentication procedures
- Using built-in security policies from the cloud supplier
- Making it possible for encryption of all information prior to the transfer
- Auditing who has access regularly over the migration period
- Finishing periodic vulnerability scans on systems with delicate info throughout the migration
- Deleting any credentials or access secrets associated with terminated employees
Consider a phased migration method
It’s never ever a great concept to migrate data in one go, especially when handling large volumes of sensitive details. A phased migration technique can help prevent data loss or other security problems and permits organizations to develop processes that avoid unapproved access while data remains in transit.
In addition, it’s usually easier to execute security procedures at a small scale and after that expand them as required over time, which allows business to proactively identify and attend to potential risks before they end up being a larger issue.
Carry out decommissioning and sanitization activities
Decommissioning describes taking a look at all of your gadgets, drives and servers that remain in your information center. Have a list that documents all of that hardware, so you can be sure to eliminate everything from your existing cloud or on-premises storage servers.

You should also guarantee any information kept in off-site places is firmly erased. In addition, it can be valuable to perform a security audit of your cloud infrastructure company to make certain they have robust security procedures in location to protect and monitor their systems.
How can you prevent information loss during cloud migration?
There are a number of measures companies can take to assist prevent data loss during cloud migrations, including:
- Using robust encryption and authentication tools for data in transit
- Restricting access to sensitive data during migration and auditing who has gain access to regularly
- Supporting critical data in a system that is not central to your migration strategy
- Utilizing a phased migration technique that allows for steady and regulated shifts
- Executing security procedures like decommissioning, which includes removing and sterilizing all devices, drives and servers from the source system
- Dealing with a cloud service provider with integrated security measures and protocols to guarantee information is protected throughout the migration process
By taking proactive steps to secure information throughout cloud migrations and thoroughly preparing the migration process to follow regulative requirements, organizations can guarantee their most important assets are not lost or compromised throughout the procedure.
