Securing Applications and Their Services with CyberArk CCP

How AKAT Technologies removed hardcoded credentials from Python, Django, Linux scripts, and systemd-managed services

One of the most important areas in modern infrastructure security is the way applications, scripts, services, and automation processes handle credentials.

In many environments, operational scripts and application services are built over time to solve business and infrastructure needs quickly. As these systems grow, credentials will almost always remain stored directly inside application files, configuration files, scripts, or service definitions.

This creates enormous risk.

Even when the server itself is protected, plain-text passwords and API keys inside local files can expose critical systems if the server, backup, repository, or configuration is accessed by the wrong person.

To address this, AKAT Technologies a powerful solution provided by CyberArk as the leading identity security provider vendor worldwide. We implemented a secure credential retrieval model using CyberArk Central Credential Provider, also known as CyberArk CCP.

The goal was clear:

Remove hardcoded passwords and API keys from Linux applications, Python/Django scripts, bash scripts, and systemd-managed services, and replace them with secure runtime retrieval from CyberArk.

The Challenge

Before the implementation, some application components and Linux services depended on locally stored secrets.

These included:

 Linux user passwords used by application logic
 Application service account credentials
 API connection keys used by Python services
 Credentials required by background workers and systemd-managed services
 Secrets stored directly in scripts or local configuration files

This approach worked functionally, but it introduced several security and operational concerns.

The main risks were:

🔹 Plain-text credentials stored on disk
🔹 Higher exposure if files were copied, backed up, or accessed
🔹 Difficult password rotation
🔹 Manual changes required when credentials changed
🔹 No central control over secret usage
🔹 Limited auditability
🔹 Increased risk of unauthorized access to critical systems

For a secure enterprise environment, this model had to be improved.

The Solution

AKAT Technologies implemented CyberArk CCP integration across the Linux application stack.

Instead of storing credentials directly inside files, the applications and services now retrieve secrets securely from CyberArk when they are needed.

The implementation covered several areas:

 Python scripts
 Django application components
 Bash scripts
 systemd-managed Linux services
 API integrations
 Linux service accounts
 Runtime environment variables
 Secure local temporary secret handling
 CyberArk-managed password rotation

This allowed the environment to move from a local, file-based credential model to a centralized, secure, auditable credential management model.

Business Value

This implementation helped transform the credential model from a local file-based approach into a secure, centralized, and auditable privileged access model.

Before: Passwords and API keys stored inside scripts and configuration files

After: Passwords and API keys managed by CyberArk and retrieved securely at runtime

This reduces the risk of credential exposure and improves operational control.

For AKAT Technologies customers, this type of implementation provides a practical and secure foundation for infrastructure automation, application security, and privileged access management.

 

How the Integration Works

The integration uses CyberArk CCP as the trusted source for secrets.

At runtime, the application or service sends a controlled request to CyberArk CCP using defined parameters such as:

  • Application ID

  • Safe name

  • Folder

  • Object name

  • Username

CyberArk validates the request and returns the required secret only if the requesting system and application are authorized.

The application then uses the secret during execution, without storing it permanently in the code or configuration.

 

The simplified flow looks like this:

 

Application or systemd service starts
        
CyberArk CCP request is sent
        
CyberArk validates AppID, Safe, Object, and access policy
        
Secret is returned securely at runtime
        
Application uses the secret
        
Secret is not printed in logs or stored in code

 

This approach significantly reduces credential exposure while keeping the application logic fully functional.

Python and Django Integration

One part of the implementation focused on Python and Django services.

Before the change, application passwords were stored directly in application files or configuration logic.

After the change, the application retrieves the password from CyberArk CCP during startup or before the protected operation is executed.

 

Example implementation logic:

def get_cyberark_password():
    “””
    Retrieve password from CyberArk CCP.
    Returns the password string or None if retrieval fails.
    “””

The Python code was updated to:

 Connect to CyberArk CCP
 Request the correct account object from the correct CyberArk Safe
 Read the returned secret from the Content field
 Stop the application safely if the secret cannot be retrieved
 Avoid printing the secret in logs

This is important because secure automation should not continue blindly when the required secret cannot be retrieved.

 

If CyberArk is unavailable, if the account object is missing, or if the response is invalid, the application fails safely instead of starting with missing or incorrect credentials.

A typical failure protection model was added:

If CyberArk retrieval succeeds:
    Continue application startup

If CyberArk retrieval fails:

    Stop startup
    Print controlled error
    Do not expose secret

This gives both security and operational teams clear behaviour during incidents.

API Key Protection

Another important part of the implementation was protecting API connection keys.

Instead of storing API keys directly in local Python files, the keys were moved into CyberArk and retrieved through CCP.

This was applied to services that communicate with external or internal API systems.

The updated code follows a reusable function model:

 

def get_cyberark_ccp_content(app_id, safe, folder, obj, username):
    “””
    Fetch a secret from CyberArk CCP and return the Content field.
    “””

This created a cleaner and more reusable approach for multiple secrets.

The function validates:

 HTTP response status
 JSON response format
 Presence of the Content field
 CyberArk errors
 Timeout handling
 Controlled exception handling

 This makes the integration more reliable and easier to maintain.

Instead of each script handling credentials differently, the same pattern can be reused across the application stack.

 

Linux Accounts Managed by CyberArk

As part of the implementation, the required Linux accounts were onboarded into CyberArk.

This included application users, service users, and other accounts required by the environment.

CyberArk now manages these accounts centrally, including:

 Password storage
 Password access control
 Password rotation
 Safe permissions
 Account ownership
 Audit trail
 Controlled retrieval by authorized applications

This is a major improvement compared to unmanaged local credentials.

It also allows security teams to apply consistent governance across accounts used by applications and automation processes.

systemd-Managed Services

The implementation was not limited only to Python code.

Some Linux services are managed by systemd, and these services also required access to secrets such as API tokens.

For these cases, AKAT Technologies implemented a secure runtime environment approach.

The goal was to avoid storing secrets directly inside service configuration files.

The model works like this:

 

systemd starts the service
        
ExecStartPre runs a root-only CyberArk fetch script
        
The script retrieves secrets from CyberArk CCP
        
Secrets are written to a protected runtime environment file
        
The service reads the secrets as environment variables
        
The service starts with the required credentials

 

The runtime secret file is created under a protected temporary runtime path and secured with strict permissions:

0600 root:root

This ensures that only root can read the file.

The systemd service is then configured to load the environment file before startup.

 

Example concept:

EnvironmentFile=/run/application/secrets.env
ExecStartPre=/usr/local/sbin/fetch_secrets_ccp.sh

 

This provides a secure and flexible pattern for services that cannot call CyberArk directly from their own application logic.

Security Controls Added

Several important security controls were included in the implementation.

1. No secrets in code

Passwords and API keys were removed from application files, Python scripts, bash scripts, and service configuration files.

2. No secrets in logs

The scripts were designed not to print passwords or tokens.

Where validation was required, only safe information such as token length or success/failure status was printed.

Example:

Secret retrieved successfully
Token length validated
Password value not printed

3. Runtime-only retrieval

Secrets are retrieved only when needed.

This reduces the amount of time secrets are present on the system.

4. Root-only temporary files

For systemd-managed services, temporary environment files are created with strict permissions.

0600 root:root

5. CyberArk access policies

Only authorized applications and systems can request the defined secrets.

This protects the accounts even if someone knows the Safe or Object name.

6. Rotation support

CyberArk can rotate passwords on a defined schedule or after use.

This makes credential lifecycle management much stronger and reduces the risk of long-lived exposed passwords.

7. Safe failure behavior

If CyberArk retrieval fails, the application or service does not continue insecurely.

This prevents services from starting in an unknown or unsafe state.

Operational Benefits

The value of this implementation is not only technical.

It improves daily operations for administrators, security teams, and application owners.

For administrators, it means:

🔹 No need to manually update passwords inside scripts
🔹 Complete password rotation
🔹 Fewer emergency changes after credential updates
🔹 Cleaner application configuration
🔹 Reduced risk during server access or troubleshooting
🔹 More consistent service startup behaviour

For security teams, it means:

🔹 Better control over privileged credentials
🔹 Centralized credential governance
🔹 Clear audit trail
🔹 Reduced exposure of sensitive data
🔹 Stronger compliance posture
🔹 Lower risk of unauthorized access

For application owners, it means:

🔹 Zero touch password rotation for critical Application services
🔹 Secrets are handled in a controlled way
🔹 Less dependency on local configuration files
🔹 More secure integration with infrastructure systems

Why CyberArk CCP Is Important

CyberArk CCP is designed exactly for this type of use case.

It allows applications and automation processes to retrieve credentials securely without requiring human interaction.

This is important in modern environments where many processes are automated and cannot rely on manual password input.

The real strength is that secrets are no longer treated as static values inside files.

They become centrally managed security objects.

CyberArk controls:

 Where the secret is stored
 Which application can retrieve it
 Which server can request it
 When the password is rotated
 Who has access to the account
 How usage is audited

This changes the security model completely.

Conclusion

Hardcoded credentials are one of the most common risks in infrastructure and application environments.

They often exist because they are convenient, but over time they become difficult to manage, difficult to rotate, and risky to protect.

By integrating CyberArk CCP with Linux applications, Python/Django services, bash scripts, and systemd-managed services, AKAT Technologies helped remove this risk and replace it with a secure, controlled, and auditable model.

This is where CyberArk provides real enterprise value.

It is not only a password vault.

It is a privileged access control layer that allows applications and automation processes to work securely without exposing sensitive credentials.

At AKAT Technologies, we believe that secure automation is not only about making systems faster.

It is about making them safer, more controlled, and easier to manage.
