How To Use AWS Cloud Key Management Service (KMS) To Protect Your Secrets ?

Last Updated : 13 Feb, 2024

In the ever-changing cloud computing landscape, protecting tangible information is paramount. Cloud Key Management Service (KMS) is emerging as the key to protecting your secrets, encryption keys, and personal data. This article will walk you through how to use Cloud KMS to strengthen the security of your packages and services.

Let’s imagine that your database server was hacked, hackers got get right of entry to all the sensitive information about your consumer and the business.
If your records are closing as plain text hackers can do what they want with this information. But your information is encrypted already hackers will have a difficult time decrypting your database statistics. ThereAnd there are main techniques of encryption purchaser-aspect encryption and server-aspect encryption.
In client-side encryption, you may encrypt your information and manage your keys. You can use KMS for it if required. Next in the server-aspect encryption your server Amazon Web Services(AWS) will encrypt your information and manage the key for you. Most of the AWS services like EBS, and S3 offer this server-side encryption with the help of KMS.

Step-By-Step Process For Creating KMS

Step 1: We need to create a CMK. To do it first, log into the AWS control console with your credentials. If you haven’t an account snatch one by way of clicking right here. Then look for KMS and it will redirect to the KMS dashboard. To Know How to Create AWS Free Tier Account Refer to Amazon Web Services (AWS) – Free Tier Account Set up.

Step 2: And then start by clicking the create key.

Step 3: Give a name to the key

Step 4: choose symmetric or asymmetric

Step 5: When choosing key configuration there is a special issue to mention. The sort of the important thing relies upon at the location that you have decided on. Some regions haven’t any uneven key and a few have. But it's miles endorsed to apply symmetric keys in the AWS. So I will pick out symmetric keys.

Step 6: Here I can pick who are the administrators of this key. And I pick my IAM consumer to hold.

Step 7: And then we are able to see what are the regulations and the get admission to rules for this person. By this, I can affirm whether the above-selected user has get right of entry to to the KMS or not.

Step 8: After those steps, you will successfully create your key. Then continue our tutorial with managing passwords on our local device. Here I actually have created a textual content record with my all passwords and touchy statistics.

Step 9: Now we can use the CMK that we have already created to create our data key. For that, we will use AWS-cli.

Step 10: Then you may configure your AWS according to the IAM consumer by using including an get right of entry to key and, a secret get right of entry to key.

Step 11: And then generate the data-key to your password file using the command shown below.

aws kms generate-data-key --key-id alias/<alias-name> --key-spec AES_256 --region <region-name>

Step 12: Then I will add that data-key into a file called, keys.txt with the following code.

aws kms generate-data-key --key-id alias/<alias-name> --key-spec AES_256 --region <region-name> > keys.txt

And then we can encrypt our data-key fields separately. To do that I use an online device to encrypt my facts-key fields. After encrypting my records-key I can encrypt my password.
Txt record by way of the use of the records-key and then delete my passwrod.Txt record. It will confirm the protection of my all passwords and as soon as I want my passwords, I can decrypt them the usage of the above statistics-key. This is how you can manipulate your passwords and sensitive statistics the use of AWS KMS.

Conclusion

In conclusion, AWS-KMS is a service to control the symmetric and asymmetric keys to make certain the safety of our information. This academic will guide you how to manipulate your sensitive information using AWS-KMS effectively. Hope you understood and live tuned for extra.
