Web Technology is widely accepted as the central source of why the world has advanced so much in the 21st century. We are now more accessible, secure, and reliable now than we were ever before.

Experts denote many reasons for this success story. However, we feel it is the cumulative result of services like AWS STS, due to which we can now achieve things that were once thought to be impossible.

What Is AWS STS? Explained

If you are a beginner and do not know what an STS is, then fret not, because this is precisely what we will decode in this guide.

In a nutshell, it is a temporary account access credential providing service offered by Amazon Web Services for your AWS account.

What is STS

STS, or as it’s known by its full abbreviation, Security Token Service, is a service offered to grant temporary access to your organization’s AWS account identity. These limited privilege credentials can be created for many purposes.

Essential Job of STS

The essential job for establishing and using an STS could be of various natures. Purposes like security checks, cross-platform working to even third-party maintenance access can be the reason behind it.

Primary Reason to Employ a Security Token Service?

Application development and management take a village to make it work. The fundamental reason why organizations prefer to use STS over handing over their organization’s permanent credentials is security.

A security token service only provides temporary access, and usually, this access expires after 12 hours. You can request AWS to extend this access.

Sometimes, it is commonly requested when different interdepartmental teams are working on a cross-platform application.

However, this access is only for 12 hours, so you can ensure that even if you use a third party for any consultancy or in a work capacity, they could not access your account once their work is done.

Scenarios & Examples Where AWS STS Use Is Paramount

The followings are the scenarios and examples where the use of AWS STS proves its worth and importance.

1. Third-Party Services Access

Application building and maintenance is a complex procedure. You need help from various professionals to make it work adequately.

Plus, regardless of how competent your own staff is, there are instances when external support is required.

STS is perfect for these instances because it allows you to get the help your application needs without compromising your organization’s credentials on a long-term basis.

Using this service, you can disable this security token to have your privacy back as soon as the work is done.

2. Transfer of Power

Sometimes web applications aren’t developed in-house; instead, they are developed by hired professionals.

Now, because of the nature of various businesses, they cannot rely even on manufacturers once they have taken over the application.

So they request the final transfer of power to be made in STS form. Once the owners have control, they can change the credentials to their liking.

This ensures the utmost privacy for their property.

3. Audits & Governance by Authorities

There are various national and international authorities involved in auditing or governing your business practices.

To ensure you are not breaking any laws, you have to share your credentials with them from time to time, and during this, STS is the perfect way to share.

This allows the concerned authority to go over your business practices and does not even compromise your security and privacy.

Because once they are done, you can change your credentials back to private.

4. Threats of Corporate Espionage

Threats of espionage are another situation where security tokens can prove fruitful.

Because if you are having doubts that someone from your organization is capable of leaking your organization’s confidential data, you can lock everything down and only provide access to the top brass through STS.

By applying these methods, you can quickly sort out who has access, who logged in, and when and if a breach happened from where it began.

5. Suspicion of Getting Your Application Hacked

Another situation where STS is ideal is when you are suspicious of getting hacked.

You can deploy this service to ensure that your previous credentials are null and void until you are sure about the severity of the hack.

If there is no attack, your original credentials will be restored after 12 hours.

But in case there were, you would have prevented it. And it would have provided you the required time to make changes to your application access and privacy settings.

6. Under/During Security Attack

We believe your application is under any form of attack at any given time. Then it is also an excellent situation where you can utilize a security token service to save your application.

This service will disable access to your account. Only the people you will provide access to will be able to access it.

Making this move can save you from catastrophe. It will also provide your security team with adequate time to come up with a plan to counter the attack you were under.

7. Vigilant Security Checks

The final situation where we believe STS could be worth using is when you perform vigilant security checks on your application.

You can test the credibility of your security team by enabling this to mimic an attack. If your security team is good enough, they will be able to counter this.

However, if they are unable to counter it. Then it will inform you about a much bigger issue of how easily your security could be compromised. And you need to update your team’s competency level.

Benefits of Deploying Amazon STS?

So far, we have discussed quite a few benefits that are enough to consider using this service. But, are you still unsure about this being the service your business needs?

To change your mind about them, we have highlighted their foremost benefits. Take a look at them, and we are confident your perception is bound to change:

1. Provides You Temporary Credentials

The most significant benefit we believe STS provides is that it allows you to generate and distribute temporary credentials.

There are many security-related measures when you are not confident in sharing your Amazon Web Services’ actual credentials.

So, in a situation like this, temporary credentials are life-saving. They allow you to perform the task that needs to be performed and simultaneously keep the power to disable this service and suspend credentials as you feel like.

2. Allows You Permission Customization Capability

The second benefit of using STS is that it allows you to customize the access you are generating through it.

Who do you want to access your application, when do you want them to access it, and how much do you want to allow them access? These are all decisions you can make if you use this service.

3. Provides You with an Enhanced Layer of Protection

The final benefit of this service is that it provides you with an enhanced layer of protection. While dealing with security tokens, you are always in charge. The moment you feel uncomfortable, you can terminate the access.

Drawbacks of Using Amazon Security Token Service?

We have informed you about the benefits Amazon’s security token service has.

However, they aren’t perfect, and to be completely honest with you, we have to share them with you. So the following are the drawbacks of using this service from AWS.

1. Too Much Power Under One Central Command

The most prominent drawback is that it allows one central source to have complete command over your application.

If you aren’t the owner and are a team member who has master access, you can compromise the complete application. This much power in one place is dangerous.

2. Slows Organization Productivity Down

The second drawback is that this constant access and non-access issue slows the work productivity in your business.

People who are developing or managing your application are constantly looking for a new access code, which can significantly hinder progress.

3. Creates Tension of Mistrust

The final drawback of using Amazon’s STS is that it can create tension of mistrust among your employees.

Security is essential, but if employees feel they are not appreciated, it can reduce their drive to work for the progression of your business.
