7 Best Practices to Secure AWS S3 Storage

Like all cloud services, you’ve to require responsibility to secure cloud storage.

In this piece of article, we'll discuss the simplest tips to secure AWS S3 storage.

Before we see the ideas for securing AWS S3 storage, we should always know why it's crucial. information technology degree

 In 2017 it had exposed critical data like private social media accounts and classified data from the Pentagon.

Since then, every organization pays close attention to securing their data stored within the AWS S3.

Does that mean S3 is an insecure storage solution from Amazon Web Services? Not in the least, S3 may be a secure storage solution, but it depends on the user how they need to secure their data.

AWS Shared Responsibility Model

Most of the solutions offered by the general public cloud provide a Shared Responsibility Model. this suggests the responsibility for the safety of the cloud platform is taken care of by AWS, and therefore the cloud customers are liable for security within the cloud.

This shared model helps mitigate against the info breaches. The below diagram shows the overall responsibility of the AWS and the customer’s responsibility for securing the info.

Study the above diagram to familiarise yourself with the responsibilities that you simply need to take. Preventative measures to secure S3 storage is important, but every threat can't be prevented. AWS provides a couple of ways to assist you in proactively monitor and avoid the danger of data breaches.

Let’s check out the subsequent best practices to secure AWS S3 storage.

Create a personal and Public Bucket

When you create a replacement bucket, the default bucket policy is private. an equivalent is applied for the new objects uploaded. you'll need to manually grant access to the entity that you simply wish to access the info.

By using the mixture of bucket policies, ACL and IAM policies give the proper access to the proper entities. But, this may become complex and hard if you retain both private and public objects within the same bucket. By mixing both the general public and personal objects within the same bucket will cause a careful analysis of ACLs, resulting in a waste of your productive time.

A simple approach is that the separate the objects into a public bucket and a personal bucket. Create one public bucket with a bucket policy to grant access to all or any the objects stored in it. Next, create another bucket to store private objects. By default, all the access to the bucket is going to be blocked for public access. you'll then use the IAM policies to grant access to those objects to specific users or application access.

Encrypting Data at Rest and Transit

To protect data during rest and transit, enable encryption. you'll set this up in AWS to encrypt objects on servers-sider before storing them in S3.

This can be achieved using default AWS-managed S3 keys or your keys created within the Key Management Service. To enforce encoding during transit by using HTTPS protocol for all the bucket operations, you want to add the below code within the bucket policy.

Utilize CloudTrail

CloudTrail is an AWS service that logs and maintains the trail of events happening across the AWS services. the 2 sorts of CloudTrail events are data events and management events. Data events are disabled by default and are far more granular. The management events ask for creating, deleting, or updating S3 buckets. and therefore the Data events ask the API calls made on the objects like PutObject, GetObject, or GetObject.

Unlike management events, data events will cost $0.10 per 100,000 events.

You create a selected trail to log and monitor your S3 bucket during a given region or globally. These trails will store logs within the S3 bucket.

CloudWatch and alerting

Having CloudTrail setup is great for monitoring, but if you would like to possess control over alerting and self-healing, then use CloudWatch. AWS CloudWatch offers immediate logging of events.

Also, you'll set up CloudTrail within a CloudWatch log group to make log streams. Having a CloudTrail event within the CloudWatch adds some powerful features. you'll found out the metric filters to enable CloudWatch alarm for suspicious activities.

Setup Lifecycle Policy

Setting up a lifecycle policy secures your data also to prevent money. By fixing the lifecycle policy, you progress the unwanted data to form it private and later delete it. This ensures that unwanted data can not be accessed by hackers and save cash by freeing the space. Enable the Lifecycle policy to maneuver the info from the quality storage to AWS Glacier for saving money.

Later the info stored within the Glacier is often deleted if it adds no more value to you or the organization.

S3 Block Public Access

AWS has taken steps to automate the functionality to dam public access of a bucket, previously a mixture of CloudWatch, CloudTrail, and Lambda was used.

There are instances where developers will accidentally make the objects or bucket for the general public. To avoid accidental access to creating the bucket or objects public, these features are available in handy. The new block public access setting feature will prevent anyone from making the bucket to be public. you'll enable this setting within the AWS console, as shown within the above video. you'll also apply this setting on the account level, as explained within the below video.

They offer recommendations in 5 categories; one of the crucial features is security. Since Feb 2018, AWS alerts you when the S3 buckets are made to be publicly accessible.

Third-party AWS security tools

Other than Amazon, there's some third party that gives security tools to secure your data. they will prevent tremendous time and keep the info secure at an equivalent time. a number of the favored tools are mentioned below:

Security Monkey

It is a tool developed by Netflix to watch the AWS policy changes and alerts if it finds any insecure configurations. Security Monkey performs a couple of audits on S3 to make sure the simplest practices are in situ. It also supports the Google Cloud Platform.

Cloud Custodian

Cloud Custodian helps you to manage resources during a cloud aligned with the simplest practices. In simple words, once you've got identified the simplest practice, you'll use this tool to scan the resources within the cloud to make sure that it's being met.

If they aren’t met, you'll use many options to send alerts or enforce the missing policies.

Cloud Mapper

Duo Security created the Cloud Mapper, which may be a great cloud visualization and audit tool. It carries an identical feature of Security Monkey to perform the scan of S3 buckets for any misconfigurations. It offers an excellent visual representation of your AWS infrastructure to reinforce the identification of further issues.


Since most of the work is administered using data, securing them should be one of the core responsibilities.

One can never know when and the way the info breach will happen. technology credit union Hence a preventive action is usually recommended. Better be safe than sorry. Securing the info will prevent thousands of dollars.

Build your own cloud and save millions!

There are numerous things to require care of, like server space, development environments, security, software stacks, software updates, hardware maintenance, that the entire platform maintenance costs tend to be overwhelming. Companies that develop and deploy applications got to allocate many of their resources to stay the platform running –resources that would rather be leveraged for software development purposes.

That’s why the necessity for cloud platform solutions arose. These solutions employ a cloud computing model to supply everything the developers got to do their work, from hosted development environments and database tools, to finish application management capabilities. Developers working within a cloud platform have access to all or any of the resources they have to create, deploy, and launch software applications. For companies, the cloud platform could provide a scalable base for brand spanking new applications that require to be delivered briefly terms. With a pay-as-you-grow model, there’s no need for long-term investments in on-premises platforms.

Why open source?

Now that we stated the advantages of cloud versus traditional, on-premises platforms, the subsequent question to ask is why an open-source cloud platform may be a better option than a proprietary cloud platform. the foremost obvious answer is that the cost: the licenses of proprietary solutions always involve higher price tags. Another important advantage is that the flexibility and freedom to settle on from a good sort of frameworks, clouds, and services.

Proprietary platforms, on the opposite side, may tie you to the tools and services they own. In exchange, they provide certain advantages, like a commitment to SLAs (service-level agreements) and relieving you from hurdles like testing and integration, but those advantages hardly overweight the advantages of openness.

Below you'll find a variety of open-source cloud platforms for the enterprise that rule today’s market.

Cloud Foundry

Originally developed by VMware (now owned by Pivotal Software), Cloud Foundry outstands for being available as an open-source, stand-alone software application, which makes it independent of cloud providers. It is often deployed on VMware vSphere or other cloud infrastructures, like HP Helion, Azure, or AWS. otherwise, you could even prefer to host it yourself on your OpenStack server. Through the utilization of buildpacks, Cloud Foundry facilitates runtime and framework support. Whenever you push an app, the Cloud Foundry Application Runtime chooses the foremost convenient buildpack for it. Then, the build pack takes care of compiling the app and preparing it for launch.

Cloud Foundry is meant to supply fast application development and deployment through a highly scalable architecture and DevOps-friendly workflows. Its language support includes Python, Ruby, PHP, Java, and Go, among many others. However, to suit adequately in Cloud Foundry is suggested that your project follows the Twelve-Factor application standard: a strategy specially designed for developing optimal software-as-a-service (SaaS) apps.

Udemy got a pleasant course on developing for the cloud with Cloud Foundry.


If you're employed intensely on SOA, you want to surely affect tons of internal and external APIs. that's the scenario where WSO2 shines, because of its API Manager, which is capable of handling the complete API lifecycle. WSO2 provides compliance with most of the wants your clients could suggest, including versioning, API documentation, and SSL offloading.WSO2 uses a store concept during which developers can find, try, and rate APIs. The deployment is straightforward and easy, providing many options to regulate the flow of the API. It also offers an auto-recovery feature, just in case an endpoint suspension occurs. of these qualities aim to scale back time-to-market, simplify the value management and, overall, improve business process agility.

A big plus of WSO2 API Manager is its easy integration with WSO2 Identity Server, an API-driven IAM (Identity and access manager) solution. This integration offers a friendly platform for authentication across cloud environments.


Cloudify is an orchestration framework designed to model applications and services while automating their lifecycles. This includes the power to deploy on any cloud environment or data center and perform continuous maintenance. It also offers tools to watch all aspects of the deployed applications, detecting failure conditions, and solving them, either manually or automatically.

One of Cloudify’s most notable features is TOSCA-based blueprint modeling. This innovation lets developers use YAML to make blueprints of the application’s topologies. YAML may be a human-readable data serialization language, used for writing definitions supported by the TOSCA specification, which provides developers a uniform thanks to describing interconnections between applications, systems, and cloud infrastructure components.

Cloudify cloud orchestration provides a solid base for IT governance and security, letting users apply access restrictions with different roles and permission levels. to speak with external services, like Kubernetes containers, cloud services (AWS, Azure, vSphere, OpenStack), and configuration management tools (Puppet, Ansible, Chef), Cloudify uses its set of official plugins, while many other services are supported by generic existing plugins.


OpenShift may be a Kubernetes-based platform, with a versatile and really fast installer and extensive API support, which allows developers to expand the platform consistent with their needs. it's built with security in mind, which is illustrated by an example: containers are expected to run as non-root users, and when that’s not the case, OpenShift requires a particular override to run the container.

Its use of Kubernetes requires a substantial server count, and it takes a particular learning curve to master it. that's why this platform isn't well-suited for little deployments unless they might become a bigger deployment within the near future.

OpenShift users highlight its fast installation and configuration procedures, also because it is straightforward to take care of modules and gears. Another plus is that the fact of getting its own Git repo. What they don’t like an excessive amount of is the difficulty of reading and interpret logs. especially, when there's a failure while uploading a project, it's hard to know where the matter is.

Learning OpenShift is straightforward.


Rede Globo, the second-largest commercial TV network worldwide, launched Tsuru as a Docker-based PaaS (platform as a service) product capable of orchestrating and running applications during a production environment. it's an open-source multi-provisioner platform that supports sites with many users, developed by Globo.com.

Tsuru users affirm that it improves substantially the time to plug without abandoning simplicity, high availability, security, or stability. It is often run during a sort of cloud infrastructure, whether or not they are public or private, as long as they're supported by a Docker machine. It also supports almost every programming language available, which provides the developers the liberty to settle on consistent with their preferences.

With Tsuru, you'll use diverse data stores, including SQL or NoSQL databases, or in-memory alternatives, like Memcached or Redis. you only select the one among your preference and plug it into your app. To manage the app, you'll choose from using the instruction or an internet interface and later deploy via Git. The Tsuru infrastructure will look out for all the nitty-gritty details.


Stackato may be a polyglot PaaS product supported by Cloud Foundry and Docker that runs on top of your cloud infrastructure and is a launching platform for your applications. Stackato users say that it provides an agile and robust application platform that helps to enhance the productivity of both cloud administrators and developers. it's well-suited from enterprise cloud deployments, combining the pliability of accessing the VM within the cloud infrastructure with the automated configuration provided by a full-featured PaaS. The supported cloud infrastructures include HP Cloud Services, Citrix XenServer, AWS, OpenStack, VMware, among others. In Stackato, each application has its own Linux container (LXC), which guarantees an efficient and secure sharing of resources. Its range of services consists of Helion Control Plane, which Stackato uses to speak with the underlying cloud and to manage service lifecycles; Helion Service Manager, a repository of add-in services available to applications; Helion Cloud Foundry, an elastic runtime designed to simplify app hosting and development; Helion Code Engine, endless delivery service integrated with Git repositories, either private or public and Helion Stackato Console, an internet interface to manage all of the Helion Cloud features.


Although it's hardly mentioned when talking about open-source cloud platforms and PaaS, the Alibaba Cloud computing business has been growing at a meteoric rate, having already conquered 50% of the Chinese public cloud market and conscientiously learning the way to serve markets outside of China. for instance, they're starting to provide billing support in US dollars across 168 countries and designing services specially tailored for overseas markets.

The cloud platform services included in Alibaba’s offering encompass many free features, including container services for Docker and Kubernetes, Container Registry, Auto Scaling, and DataWorks, a secure environment for offline data development. Its services are well documented and accompanied by everything you'll get to start migrating your apps to the cloud directly, like many tutorial videos. Following a couple of simple steps and without investing a dollar, Alibaba invites you to start out building in no time.


Luckily enough for all developers, openness rules the cloud world. a few years ago, competing for container technologies (Docker, Kubernetes, Mesos, Nomad, ECS, to call a few) threatened to divide the market into watertight compartments, generating considerable risks whenever you needed to select a platform. But, although nowadays there are more platforms to settle on from, the differences between today’s open-source choices are only on the details: different cost schemes, different management tools, different approaches to security. In other words, if you choose an open-source cloud platform today and you’re not satisfied, you'll attend another one tomorrow, and therefore the costs won't kill you.

With the knowledge we gave you here, you'll hopefully be ready to choose the platform that better suits your needs and allows you to ditch headaches like server capacity, middleware, frameworks, virtual machines, data stores, and so on. information technology degrees

Once you've got freed yourself of all that, you'll be ready to put all of your resources and every one your attention on the one thing that basically matters to you: deliver your kick-ass application to your users as fast as possible, and keep them happy while using it.
