What is AWS CodeCommit? Streamlining Source Control in the Cloud.

In the era of cloud computing, source control is a pivotal aspect of the workflow, ensuring that code changes are managed efficiently, collaborative efforts are streamlined, and the integrity of the codebase is maintained. Amazon Web Services (AWS) offers a robust solution for source control in the cloud with AWS CodeCommit. This article delves into the features, benefits, and use cases of AWS CodeCommit. We will also go ahead and create a code commit repository and clone the repo to our local machine, add files, commit and push them to our AWS code repository.

What is AWS CodeCommit?

AWS CodeCommit is a version control service hosted by Amazon Web Services that allows developers to store and manage their source code, binaries, and other assets in the AWS cloud. Additionally, it is designed to work seamlessly with existing Git tools, making it easy for developers to integrate it into their current workflows.

Key Features of AWS CodeCommit.

Fully Managed Service: AWS CodeCommit takes care of the backend infrastructure, so developers can focus on writing code. There are no servers to manage.

Scalability: CodeCommit can handle repositories of any size, with the ability to scale up as your project grows.

High Availability and Durability: your repositories are always accessible and your data is protected against loss.

Security: CodeCommit integrates with AWS Identity and Access Management (IAM) to provide robust access control. You can use IAM policies to define who can access your repositories and what actions they can perform.

Integration with AWS Services: CodeCommit integrates seamlessly with other AWS services such as AWS CodeBuild, AWS CodeDeploy, and AWS CodePipeline. This allows you to create a complete CI/CD pipeline using AWS tools, enhancing your development and deployment workflows.

Standard Git Interface: CodeCommit supports the standard Git interface, so developers can use their preferred Git client, command-line tools.

Getting Started with AWS CodeCommit

Prerequisite.

Make sure you have full permission to Codecommit, or you can log in as an administrative user additionally, you should have git installed and configured on your machine.

Create a Repository

In the code commit UI on the left-hand side, select repositories then click Create Repository.

In the create repository dashboard, under repository settings, name your repo, will call mine demo-commit-repo.

Codecommit is encrypted by default using KMS, but you can also choose your custom keys. We will leave it at AWS-managed keys with KMS.

Leave all other settings as default then click Create Repository.

Success, we are greeted with connection steps. We can see HTTPS, SSH, HTTPS(GRC).

If you don’t see SSH then it means you are connected as the root user.

We will for now use HTTPS git credentials for Codemmit to connect to our git repository.

So let us log in to the I AM console.

Select users. Click your username, move to the security tab then scroll all the way down to HTTPS for git credentials.

Click on generate and your codecommit credentials will be generated. Click the download button.

Go back to the codecommit repository select your repo then click the drop-down button of the clone URL then select clone HTTPS.

In this case, it will copy the HTTPS-type URL.

Use your preferred Git client to clone the repository to your local machine. This allows you to start adding code and making changes.

Go back to your terminal and type in git clone and paste in the cloned URL. When you press enter, you will be prompted for your username and password. Paste them in then press enter.

We have cloned our remote repo into our local machine.

With the repository cloned, you can push your changes to CodeCommit.

We will now copy a few files into our directory, commit these files, and push them to our remote repo.

Using linux command make sure you are in the repo directory then add copy files to your repo.

Using git add the files and then commit the changes as shown in the picture bellow.

Once the changes are commited, you can then push them to the remote repo by using the below command.

Now let’s go and check codecommit, and yes indeed the new files have been pushed to the codecommit repository.

If you click on the commits on the left side of the repo UI, you can see the commit history.

This brings us to the end of this blog. AWS CodeCommit offers a powerful, secure, and scalable solution for source control in the cloud.

Zero Trust Network Access (ZTNA) Best Practices Guide

Zero Trust Network Access (ZTNA) Best Practices Deployment Guide

Zero Trust Network Access (ZTNA) is a holistic approach to network security that combines multiple layers of protection. It commences with robust user authentication, employs the principle of least privilege, incorporates micro-segmentation to isolate and protect critical assets, and implements continuous monitoring to detect and respond to anomalies. User and device profiling, secure access control, and context-aware policies further enhance security. Secure remote access, an application-centric approach, and the use of secure web gateways and firewalls add additional layers of defense. By adopting this comprehensive approach, organizations can significantly enhance their network security and reduce the risk of breaches and data loss.
Implementing a Zero Trust Network Access (ZTNA) solution is crucial for enhancing network security in today’s digital landscape. Here, we provide a concise summary of the best practices for ZTNA implementation, which are essential for maintaining a robust security posture.
Identifying and Verifying Users and Devices

The foundation of Zero Trust Network Access (ZTNA) lies in robust user authentication, ensuring the security in the digital realm. This security measure involves employing advanced methods, such as multi-factor authentication (MFA) or digital certificates, to unequivocally verify the identity of both users and devices. This two-fold verification process goes beyond traditional username and password authentication, substantially increasing the confidence in the system’s ability to determine the legitimacy of access requests. By utilizing MFA, users are required to provide multiple pieces of evidence to establish their identity, making it significantly more challenging for unauthorized individuals or devices to infiltrate the network.

Least Privilege Access

In the realm of network security, the principle of least privilege is a fundamental concept. It dictates that users and devices should be granted the minimum level of access necessary to carry out their respective functions. This approach plays a pivotal role in minimizing potential damage in the event of a security breach. By restricting access to only what is essential, the attack surface is significantly reduced. Even if a malicious actor manages to compromise an account or device, the extent of the damage they can inflict is curtailed, as their access is limited to a narrow scope.

Micro-Segmentation

Micro-segmentation serves as a potent safeguard within the ZTNA framework. It involves dividing the network into smaller, isolated segments or zones, effectively creating secure compartments. The primary objective is to limit lateral movement within the network. In doing so, the risk of unauthorized access to critical assets is dramatically diminished. This approach isolates and fortifies these assets, rendering them impervious to threats that may have penetrated other parts of the network. Micro-segmentation exemplifies a proactive defense strategy, ensuring that even if a breach occurs, the potential for damage is confined to a specific zone.

User and Device Profiling

In the realm of ZTNA, creating comprehensive profiles of users and devices is a fundamental practice. These profiles encompass a wealth of information, including user roles, behavior patterns, and security postures. This in-depth understanding of the entities seeking access to the network plays a vital role in effective access control. By tailoring access permissions based on these profiles, organizations can ensure that the right individuals and devices have access to the right resources, while also flagging any deviations from the norm for further investigation.

Secure Access Control

The heart of ZTNA lies in dynamic access control policies that adapt to the ever-changing landscape of network security. These policies take into account a variety of factors, such as user behavior and the prevailing risk level. This adaptive approach ensures that security policies remain effective, regardless of the evolving circumstances. Security is no longer a one-size-fits-all approach but rather a finely tuned orchestration that responds to the nuances of each access request.

Context-Aware Policies

Context-aware access policies take the security of ZTNA to a new level. These policies consider a multitude of contextual factors, including the user’s location, the time of access, and the sensitivity of the requested resource. By factoring in these variables, access decisions become more fine-grained and secure. For instance, access to sensitive data may be restricted when a user is attempting to log in from an unfamiliar location, even if their credentials are valid. These policies add an extra layer of protection, enhancing security.

Secure Remote Access

Remote access is a critical aspect of ZTNA, and the approach to it is far from traditional. Rather than relying on conventional Virtual Private Networks (VPNs), organizations are increasingly implementing alternatives such as Software-Defined Perimeters (SDPs). SDPs offer enhanced remote security by dynamically adjusting access based on user profiles and contextual factors. This adaptive approach ensures that remote access remains secure and compliant with the principles of Zero Trust.
