As a result, preserving data from inadvertent deletion should be at the top of the priority list. You can add an extra degree of protection to <a href=\"https:\/\/www.workfall.com\/learning\/blog\/how-to-fetch-contents-of-json-files-stored-in-amazon-s3-using-express-js-and-aws-sdk\/\">AWS S3<\/a> by configuring buckets to enable MFA delete, which can help prevent unintentional bucket deletions and their contents.<\/p>\n\n\n\n<p class=\"has-text-align-justify\">Securing objects from accidental deletion or an intended deletion is one of the important security concerns as it may affect the customers and the business.<\/p>\n\n\n\n<p class=\"has-text-align-justify\">To avoid such scenarios, AWS has a feature called MFA delete which can be implemented on the S3 buckets with Versioning Enabled. In this blog, we will demonstrate step-by-step implementation for enabling MFA delete on a S3 bucket.<\/p>\n\n\n\n<h2>In this blog, we will cover:<\/h2>\n\n\n\n<ul><li>What is MFA delete?<\/li><li>Authentication required for MFA delete<\/li><li>Enable MFA on S3 bucket<\/li><li>Enable Versioning on S3 bucket<\/li><li>Install Google Authenticator<\/li><li>Activate MFA<\/li><li>Setup Access Key ID and Secret Access Key for Root Account<\/li><li>Install and Configure AWS CLI<\/li><li>Verify MFA delete<\/li><li>Testing and Verification<\/li><li>Disable MFA delete on S3 bucket<\/li><li>Conclusion<\/li><\/ul>\n\n\n\n<h2><strong>What is MFA delete?<\/strong><\/h2>\n\n\n\n<p class=\"has-text-align-justify\">When you try to delete a file, MFA delete simply protects the versioning of the file; when you delete the file, it actually deletes it from the bucket but preserves a version. When deleting through the AWS interface, the behavior is similar; it deletes the file but does not allow you to delete the version.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https:\/\/lh5.googleusercontent.com\/UnERNA1xnUwRfP9C9f_XdhuCjEbDN6d5pheFH9iIu0JcnA0ZpCvqdJm05dZmnQce6YYdY8RCpvjozNzVNqJfhDhfIGe-Qm1HiKDwrDZhnrcHwBV5sidzwwaBlZI7NFoaqGde3D5cdkGoMIXMB4CEKw\" alt=\"What is MFA delete?\"\/><\/figure>\n\n\n\n<p>This regulation can assist you in meeting the following compliance requirements:<\/p>\n\n\n\n<ul><li>Payment Card Industry Data Security Standard (PCI DSS)<\/li><li>General Data Protection Regulation (GDPR)<\/li><li>APRA<\/li><li>MAS<\/li><li>NIST 800-53 (Rev. 4)<\/li><\/ul>\n\n\n\n<p>Working with the AWS Well-Architected Framework is made easier with this rule.<\/p>\n\n\n\n<p>Versioning plays an important role in keeping multiple versions of the same file, using which MFA delete works.<\/p>\n\n\n\n<p>MFA (Multi-factor Authentication) adds a layer of security from:<\/p>\n\n\n\n<ul><li>Changing the versioned state of the objects<\/li><li>Permanent delete of the versioned objects<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https:\/\/lh6.googleusercontent.com\/LGZBlEWZUa4pzH0nNDZ7ETXokQqDl5JEztw4CYe2HljPxHC1rwXA9SNcGlDywGjIcZ4eI0JLTq1S-jMd48DQfmgXbC6b4WSxsXcQnpaz0-Cn95nfhBeLb3kglybQdNhZpgs35YFJzrceyJqkKykwhQ\" alt=\"What is MFA delete?\"\/><\/figure>\n\n\n\n<h3><strong>Authentication required for MFA delete<\/strong><\/h3>\n\n\n\n<p>While configuring MFA delete on the S3 buckets, there are two forms of authentication required.<\/p>\n\n\n\n<ul><li>Your security credentials which is Access Key ID and Secret Access Key<\/li><li>Six-digit code from the approved authentication device such as Google authenticator installed on mobile<\/li><\/ul>\n\n\n\n<h2>Hands-on<\/h2>\n\n\n\n<h3><strong>Enable MFA on the S3 bucket<\/strong><\/h3>\n\n\n\n<p>To create an S3 bucket, Go to the S3 console<\/p>\n\n\n\n<p>Click Create bucket, Enter the name for the S3 bucket and then click Create bucket.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https:\/\/lh5.googleusercontent.com\/HoHtLuQVAdpiI9FelHelKVJsBBjQgm0-GgA07vD4x4uhA-H1tMN1c4JPBpvyPI_THdEZnAxkm4WSICsYTbuLSmzOKKoOyaIyq6HadjYAmkFTVIvUzWLj0GeojBdYJrJ-_zkKcZGzKUA5wKPo_yQVpg\" alt=\"\"\/><\/figure>\n\n\n\n<p><strong>Enable Versioning on S3 bucket<\/strong><\/p>\n\n\n\n<p class=\"has-text-align-justify\">After the S3 bucket is created, Versioning can be either enabled using the command line interface or using the AWS console.<\/p>\n\n\n\n<p>To enable versioning using the AWS console, Open the S3 console, Select the bucket.<\/p>\n\n\n\n<p>Then select Properties.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https:\/\/lh6.googleusercontent.com\/yH2HISFCC-WAbetFqBzKr8niR2au1tYxYEJYlaqz5AnGOjNl72rf5md-GiYF_t2fs4We7Zf3K3k09Nf8r_7iwSrLUdXketRIE3T2qW4QcdmsOCybPyVw1MsgNLx41YIa2usmoXPF4glk1G7XxgW4Ww\" alt=\"\"\/><\/figure>\n\n\n\n<p>Click Edit for Bucket Versioning<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https:\/\/lh4.googleusercontent.com\/EwN-f-dPYZdlx1qb2ELyMGzPcKWWUET_yY8nYc4etxRqOWNuYqRpscRR_RnfSo--dbshhfb_iHvC1yXhqrTSqk03oU5xrDrEbK2doW75bwgl2JnK4rZ7G5Kxlqy1dld3Vls9GgNLvrP1HHPAWIl36Q\" alt=\"\"\/><\/figure>\n\n\n\n<p>&nbsp;And then Choose Enable and Click Save changes.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https:\/\/lh3.googleusercontent.com\/Mjht-7RU0IEoe97xv6oBACAyPC_2tlBD3YhtCFGOjNkWnJCC_lB59b4qFNYlwILGGj4sawnjATRiKJ3DpluAblJLOWM8S1fqRyy0O1_7B-wZa-zUexmil6j5c3AvSgcVgG1O0-gKBNlfOMDew4PdYQ\" alt=\"\"\/><\/figure>\n\n\n\n<p>Versioning for the S3 bucket is Enabled.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https:\/\/lh6.googleusercontent.com\/0cQEhjq9VugWGkYmElGP155SvnWrq90NtYk21qZBIV8XKG-t34yOmDaJfhD4mSqeGs31G8XE2INUjfZgOlu2xfiPEl7ww4e8ncGMA5GEmxzHDE-XDaN0d0W0aqj-5orw1kHHkdtyBhpN60pCi0JzUg\" alt=\"\"\/><\/figure>\n\n\n\n<p class=\"has-text-align-justify\">Enabling versioning on the S3 buckets can be done using IAM users.

MFA delete adds a layer of security for the objects stored in the S3 bucket which can only be Enabled and Disabled by the Root User. Deleting the versioned object is not even possible for the root user unless MFA is used. We have implemented a strategy to secure the file stored in the S3 bucket using versioning and MFA delete features offered by AWS.
