Understanding the Requirements for M2131 Logging

M2131 logging is a compliance requirement that has become increasingly important in today's digital landscape. With the rise of data breaches and privacy concerns, organizations are under immense pressure to ensure that their log data is properly managed and secured.

But what exactly are the requirements for M2131 logging? In this section, we will delve deeper into the specifics of this compliance standard and explore how Azure Data Explorer (ADX) and Azure Data Lake Gen 2 can help you meet these requirements effectively.

Firstly, let's define what M2131 logging is. M2131, also known as M-21-31, is a memorandum issued by the U.S. Office of Management and Budget (OMB) in 2021. This memorandum, titled "Improving the Federal Government’s Investigative and Remediation Capabilities Related to Cybersecurity Incidents," is part of the federal government's response to increasing cybersecurity threats, particularly in the wake of significant incidents like the SolarWinds breach. M-21-31 provides detailed guidance for federal agencies to enhance their visibility and response capabilities before, during, and after a cybersecurity incident.

The memorandum was issued in support of Executive Order 14028, "Improving the Nation's Cybersecurity," signed by President Biden in May 2021. This executive order aims to bolster cybersecurity across federal civilian agencies and the private sector, focusing on areas such as sharing threat information, securing software development processes, and establishing standard operating procedures for responding to security incidents.

M-21-31 introduces a maturity model for event log management across federal agencies, categorized into four event logging (EL) tiers, ranging from EL0 (Not Effective) to EL3 (Advanced). These tiers define the requirements for log management, such as the types of logs to be collected, data details to be included in the logs, log retention standards, and security measures for log information. For instance, the basic requirements (EL1) include details like timestamp, event type, device ID, IP addresses, and user information in the logs, while the advanced requirements (EL3) encompass automated response playbooks and integration of security tools.

Federal agencies are responsible for assessing their current maturity levels against this model and addressing any gaps to meet the specified requirements within set timelines. They are also encouraged to share relevant logs with cybersecurity authorities like the Cybersecurity and Infrastructure Security Agency (CISA) and the FBI to help protect federal information systems and manage security risks.

In addition to having an audit trail, organizations must also ensure that their log data remains tamper-proof and easily accessible for at least one year. This ensures that any suspicious activity can be traced back and investigated promptly.
