T0127 - Exposed database

Exposing a database to the public internet can be a critical security issue, as attackers can use it to gain access to sensitive information. In the context of cloud security and infrastructure as code, this attack technique typically involves misconfigured security group rules or network access control lists (ACLs) that allow public access to a database. It can also occur when developers or system administrators accidentally expose database credentials or when misconfigured server configurations allow database access.

Mitigations

ID
TYPE
SUMMARY
DESCRIPTION
M1270
Mitigation
Mitigation Implement proper access control for databases Review and restrict security group rules, network ACLs, and firewall rules associated with the database to allow access only from authorized IP addresses or CIDR blocks.
Avoid allowing unnecessary public access and follow the principle of least privilege by granting only the minimum permissions required for legitimate users and applications.
M1271
Mitigation
Mitigation Protect database credentials Avoid hardcoding database credentials in code or configuration files.
Use secure methods for managing and storing credentials, such as encrypted secrets management tools or credential vaults. Limit the access and exposure of database credentials to only authorized personnel, and promptly revoke access for users who no longer require it
M1272
Mitigation
Mitigation Audit server configuration Regularly audit server configurations to ensure that there are no misconfigurations that allow unauthorized database access.
Check for misconfigured firewall rules, open ports, and any other configurations that may expose the database to the public internet. Follow security best practices and recommendations from your cloud service provider for securing database instances
M1550
Mitigation
Mitigation Implement strict access control for clouds Limit access to cloud resources to only authorized users and ensure that proper authentication and authorization mechanisms are in place.
Mitigation Implement strict access control for clouds Limit access to cloud resources to only authorized users and ensure that proper authentication and authorization mechanisms are in place.
M1720
Mitigation
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.

SUMMARY
DESCRIPTION
D1131
Detection
Detection Implement SIEM Implement a SIEM system to centralize and analyze logs and events from various sources, including user account-related activities.
Use SIEM rules or correlation rules to detect any abnormal or suspicious user account-related activities, such as multiple failed login attempts, changes to account settings outside of normal patterns, or simultaneous login attempts from different locations.
D1260
Detection
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.
D1261
Detection
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
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.
D1270
Detection
Detection Implement network scanning Conduct regular network scans to identify open ports and services exposed to the public internet.
Look for unexpected or unauthorized open ports associated with services that may indicate misconfigurations or vulnerabilities.
D1510
Detection
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.
