Describe in detail how I can leverage macOS system logs to access and export security event information. This must be performed using only built-in mac binaries

Output

I'll provide a detailed guide on how to access and export security event information from macOS system logs using only built-in binaries. Here are multiple approaches: 1. Using log show command: 

1
2
3
4
5
6
7
8
# View last hour of security events
log show --predicate 'subsystem contains "com.apple.security"' --last 1h

# View specific timeframe
log show --predicate 'subsystem contains "com.apple.security"' --start "2023-01-01 00:00:00" --end "2023-01-02 00:00:00"

# Export to file
log show --predicate 'subsystem contains "com.apple.security"' --last 24h --style syslog > security_events.log
2. Using log stream for real-time monitoring: 
1
2
3
4
5
# Stream security events in real-time
log stream --predicate 'subsystem contains "com.apple.security"'

# Stream with level filtering
log stream --level error --predicate 'subsystem contains "com.apple.security"'
3. Specific security event types: 
1
2
3
4
5
6
7
8
# Authentication events
log show --predicate 'process == "authentication" OR process == "authd"'

# Firewall events
log show --predicate 'process == "socketfilterfw"'

# Login/logout events
log show --predicate 'eventMessage CONTAINS "login" OR eventMessage CONTAINS "logout"'
4. Complex queries: 
1
2
3
4
5
# Multiple conditions
log show --predicate '(subsystem contains "com.apple.security") AND (eventMessage CONTAINS "failed" OR eventMessage CONTAINS "error")' --last 24h

# Specific process with security events
log show --predicate '(subsystem contains "com.apple.security") AND (process == "sudo")' --last 24h
5. Format output: 
1
2
3
4
5
# JSON format
log show --predicate 'subsystem contains "com.apple.security"' --last 1h --style json > security_events.json

# Syslog format
log show --predicate 'subsystem contains "com.apple.security"' --last 1h --style syslog > security_events.log
6. System.log access: 
1
2
3
4
5
# View system.log
cat /var/log/system.log

# Filter system.log for security events
grep -i "security" /var/log/system.log > security_filtered.log
7. Audit logs: 
1
2
3
4
5
# View audit logs (requires root)
sudo praudit /var/audit/current

# Export audit logs
sudo praudit /var/audit/current > audit_log.txt
Additional Tips: 1. Create aliases for common queries: 
1
2
# Add to ~/.zshrc or ~/.bash_profile
alias security_logs='log show --predicate '\''subsystem contains "com.apple.security"'\'' --last 1h'
2. Combining with other utilities: 
1
2
3
4
5
# Count security events by type
log show --predicate 'subsystem contains "com.apple.security"' --last 24h | grep -i "error" | wc -l

# Search for specific IP addresses
log show --predicate 'subsystem contains "com.apple.security"' --last 24h | grep -E "([0-9]{1,3}[\.]){3}[0-9]{1,3}"
3. Regular monitoring: 
1
2
3
4
5
6
# Create a simple monitoring script
#!/bin/bash
while true; do
    log stream --predicate 'subsystem contains "com.apple.security"' >> security_monitor.log
    sleep 1
done
Important Notes: 1. Some commands may require sudo privileges 2. Log retention varies based on system settings 3. Consider disk space when exporting large log files 4. Use appropriate time ranges to manage performance 5. Some security events may be in different subsystems To maintain a comprehensive security monitoring system: 1. Regular exports: 
1
2
3
# Create daily exports
mkdir -p ~/security_logs
log show --predicate 'subsystem contains "com.apple.security"' --last 24h > ~/security_logs/security_$(date +%Y%m%d).log
2. Cleanup old logs: 
1
2
# Remove logs older than 30 days
find ~/security_logs -name "security_*.log" -mtime +30 -delete
This provides a robust foundation for security monitoring using only built-in macOS tools. Adjust the predicates and time ranges based on your specific needs.

# Group events by process
log show --predicate 'subsystem == "com.apple.security"' | awk '{print $3}' | sort | uniq -c | sort -nr

# Find most common events
log show --predicate 'subsystem == "com.apple.security"' | grep -o "security.*" | sort | uniq -c | sort -nr
Important notes: - Some log access may require sudo privileges - Logs are automatically rotated by the system - The log command supports extensive filtering using NSPredicate syntax - Consider disk space when exporting large log files - Real-time monitoring can be resource-intensive Best practices: 1. Always specify a time range to limit output 2. Use appropriate predicates to filter relevant events 3. Export critical logs for backup and analysis 4. Monitor system resource usage when running extensive log queries 5. Regular review of security events for potential issues This approach using built-in tools provides a robust way to monitor and analyze security events on macOS without requiring additional software installation.

7. Filtering by Severity:

# Show only error-level events
log show --predicate 'subsystem == "com.apple.security" AND messageType == "Error"'

# Count of failed authentication attempts
log show --predicate 'process == "authd" AND eventMessage CONTAINS "failed"' --last 24h | wc -l
Important Tips: - Use `--info` flag to see available predicates and subsystems - Timestamps are in local time zone by default - Use `--timezone UTC` for UTC timestamps - Add `--debug` for troubleshooting queries - Use `--style syslog` for human-readable output - Use `--style json` for machine-readable output Best Practices: 1. Always specify a time range to prevent overwhelming system resources 2. Use specific predicates to filter relevant information 3. Export to files for long-term storage 4. Consider compression for large exports: 
1
log show --predicate 'subsystem == "com.apple.security"' --last 24h | gzip > security_events.log.gz
These commands can be combined into scripts for automated collection and analysis. Remember that some logs may require administrative privileges, so you might need to use `sudo` for certain operations.

Best Practices: 1. Always use specific time ranges or limits to avoid overwhelming output 2. Export sensitive logs to secure locations 3. Use appropriate predicates to filter relevant information 4. Consider regular archiving of important logs 5. Use proper file permissions when saving exported logs Tips for Analysis: 1. Use grep for additional filtering:

2. Combine with other tools: 
1
2
# Count events by type
log show --last 24h --predicate 'subsystem == "com.apple.SecurityServer"' | grep -i "failed" | wc -l
3. Parse JSON output: 
1
log show --style json --predicate 'subsystem == "com.apple.SecurityServer"' | grep -i "failed" | jq '.'
Remember: - Some commands may require sudo privileges - Large time ranges may take significant time to process - Consider system performance impact when running extensive log queries - Regular log rotation may affect availability of historical data - Always verify time zones when analyzing logs This approach uses only built-in macOS binaries and provides comprehensive security event information access and export capabilities.

# Create an alias for common queries
echo 'alias seclog="log show --predicate '\''subsystem == "com.apple.security"'\'" --last 1h' >> ~/.zshrc
Important tips: - Use `sudo` when necessary for accessing privileged logs - Always specify time ranges to manage log volume - Consider compressing large exports:

These commands use only built-in macOS binaries and provide a comprehensive way to access, filter, and export security event information. The logs can be used for security auditing, troubleshooting, or compliance purposes. Remember to regularly clean up exported log files as they can grow large over time:
