T0135 - Vulnerable CICD system
An attacker can target the CI/CD system itself and exploit vulnerabilities in the system, such as insecure configurations or outdated software.
The attacker may also target the build scripts, which could contain secrets and sensitive information, allowing them to gain access to the underlying systems or inject malicious code into the software being built.
Some common vulnerabilities in CI/CD systems include insecure storage of credentials, unsecured APIs, and outdated software components.
Additionally, attackers may take advantage of misconfigured permissions, such as overly permissive access controls that allow them to escalate privileges or access sensitive information.

Mitigation
Implement regular patches and updates
Regular patches and updates are necessary to improve the security, performance, and reliability of software and systems.
They include bug fixes, security updates, and performance improvements.
Regular patches and updates also ensure compatibility with new technologies and can help maintain compliance with regulatory standards.
Failure to install patches and updates can leave systems vulnerable to security threats, cause system failures or crashes, and limit the functionality of software and systems.

Mitigation
Implement strong authentication mechanisms
Authentication is the process of verifying the identity of a user or entity accessing the SCM system.
Strong authentication typically involves using multiple factors to verify the user's identity, beyond just a username and password.
This may include factors such as something the user knows (e.g., password), something the user has (e.g., smart card or token), and something the user is (e.g., biometric data like fingerprint or facial recognition).
Multi-factor authentication (MFA) can significantly enhance the security of SCM systems by adding an additional layer of protection against unauthorized access.
M1861
Mitigation
Implement strong authorization mechanisms
Strong authorization ensures that users only have access to the resources and actions that are necessary for their job functions and responsibilities, and nothing more.
This can be achieved through proper access controls, such as role-based access control (RBAC) or attribute-based access control (ABAC), which define fine-grained permissions and privileges for users, groups, and repositories in the SCM system.
Regularly review user permissions and remove all unnecessary permissions for specific users.

Detection
Implement regular security audit and review
Conduct regular security audits and vulnerability assessments of your systems and storages configurations to identify and address any potential misconfigurations or vulnerabilities that could lead to exposed storage.
This includes reviewing access controls, encryption settings, and other security configurations to ensure they are aligned with best practices and organizational security policies.

Detection
Implement penetration testing
Penetration testing, also known as ethical hacking or vulnerability assessment, is a proactive approach to mitigating cybersecurity risks.
It involves simulating real-world cyber attacks on a system, network, or application in a controlled and authorized manner to identify vulnerabilities and weaknesses that could be exploited by malicious actors.
D1262
Detection
Implement vulnerability assesment
Vulnerability assessment is a proactive approach to mitigating cybersecurity risks by systematically identifying, evaluating, and prioritizing vulnerabilities in a system, network, or application.
It involves conducting regular assessments to identify potential weaknesses that could be exploited by attackers, and taking appropriate actions to remediate or mitigate those vulnerabilities.

Detection
Implement Intrusion Detection System and anti-malware
An intrusion detection system (IDS) is a security tool designed to detect and alert on unauthorized access to a computer system or network.
Implementing intrusion detection systems (IDS) and anti-malware software can help to identify and block malicious activity.
IDS is a critical security tool that helps organizations to detect and respond to security incidents in a timely manner.
By providing real-time monitoring and analysis of network traffic, IDS can help organizations to stay ahead of potential threats and reduce the risk of a security breach.
D1590
Detection
Implement continuous monitoring and logging of the CI/CD process
Continuous monitoring and logging of the CI/CD process can help organizations detect any unusual activities or deviations from the standard workflow.
This can include monitoring the pipeline for unusual resource requests or unauthorized access attempts, as well as analyzing logs for unusual activity that may indicate a potential security breach.
By establishing a baseline of normal behavior and regularly comparing it to current activity, organizations can quickly identify and respond to any anomalous behavior.
Implementing automated alerts and notifications for suspicious activity can also help security teams respond promptly to potential threats.
