Best Practices For Event Logging and Threat Detection

Executive summary

This publication defines a baseline for event logging best practices to mitigate cyber threats. It was developed by the Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC) in cooperation with the following international partners:

• United States (US) Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI) and the National Security Agency (NSA)
• United Kingdom (UK) National Cyber Security Centre (NCSC-UK)
• Canadian Centre for Cyber Security (CCCS)

• Singapore Cyber Security Agency (CSA)
• The Netherlands General Intelligence and Security Service (AIVD) and Military Intelligence and
• Security Service (MIVD).

Event logging supports the continued delivery of operations and improves the security and resilience of critical systems by enabling network visibility. This guidance makes recommendations that improve an organisation’s resilience in the current cyber threat environment, with regard for resourcing constraints. The guidance is of moderate technical complexity and assumes a basic understanding of event logging.
