Why should you be concerned about Jenkins security?

Jenkins is a programme that interacts with various components, services, servers, etc., so you should consider security of your Jenkins system carefully. Jenkins needs access to those services and/or credentials in order to complete this.

Consider that your Jenkins application is running on AWS and that it requires access to ECR, ECS, and EC2. To accomplish this, you would provide Jenkins EC2 admin access and an IAM user—not the best choice available, but still a highly popular one.

Imagine a situation where someone gains access to your Jenkins instance and finds the environment variables where your IAM credentials were stored.

This person can now cause chaos for you, your business, and your clients, which is not a good scenario to be in.

By exercising caution, you should try to stay away from this kind of terrible circumstances. As they say, prevention is always preferable to cure.
