Output

**Leveraging macOS System Logs for Security Event Information** macOS maintains extensive system logs that capture various system-related events, including security-relevant occurrences. You can utilize these logs to access and export security event information using built-in macOS binaries: 1. **Identify Security-Related Logs:** The primary macOS system log file is `/var/log/system.log`. However, for security-specific events, it's recommended to focus on the following additional log files: - `/private/var/log/security.log` - `/private/var/log/auth.log` - `/private/var/log/appfirewall.log` - `/private/var/log/audit.log` (if auditd is enabled) 2. **Access the Logs:** - **Using Terminal:** Open Terminal and navigate to the desired log file directory, typically `/var/log` or `/private/var/log`. Use the `tail` command to view the last portion of the log:

     tail -n 100 /var/log/security.log
     tail -n 100 /private/var/log/auth.log
     

- **Using Console.app:** Open Console.app located in `/Applications/Utilities/`. In the left sidebar, select "System Logs" and then expand the "syslog" or "private" directories to access the desired log files. Filter the events based on the keyword "security" or relevant search terms. 3. **Export Security Logs:** - **Using log command:** This command allows you to extract specific log lines matching a pattern. For example, to export all security-related events from `/var/log/system.log`, use:

     log show --predicate 'category == "security"' --info > security.log
     

- **Using Console.app:** In Console.app, select the events you want to export. Right-click and choose "Export" to save the events to a file in various formats such as Plain Text, JSON, or XML. **Tips:** - **Enable Auditd:** Auditd is a powerful auditing daemon that can collect and log detailed security events. Enable it using the following command:

   sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.auditd.plist
   

- **Configure Remote Logging:** You can configure macOS to send logs to a remote syslog server using the steps outlined in Apple's support article: [Configure remote logging](https://support.apple.com/en-us/HT200108). By following these steps, you can leverage macOS system logs to access and export valuable security event information that can aid in incident response and security monitoring efforts.

Output

**Accessing macOS System Logs** **1. Terminal:** Open Terminal (Applications > Utilities > Terminal). **2. Use 'console' Command:**

console

This will open the Console utility that displays system logs. **Filtering Security Logs** **1. Search Bar:** Type "Security" in the search bar to filter logs for security events. **2. System Domains:** Expand the tree on the left pane and navigate to: - Authentication and Authorization - Security and Privacy - System Configuration **Exporting Security Event Information** **1. Export as Text:**

console

Select the desired logs, then click on the Gear icon > "Export As" > "Text". Choose a location to save the text file. **2. Export as Syslog:**

syslog -D -F exported-syslog.log

Run this command in Terminal to export all system logs as a Syslog file. You can specify a destination file name with "-F". **3. Export Using 'log' Command:**

log stream --style json -p security --file exported-security.json

This command exports security logs as a JSON file. Adjust the "-p" argument to specify specific log components. **4. Export Using 'ausearch' Command:**

ausearch -f exported-security-ausearch.log --filter "%(subject)s %(/action)s %(/object)s" --format syslog

This command exports security-audit logs in a filtered and serialized format. **Additional Options:** * **Export All Logs:**

console -e > exported-all-logs.txt

* **Tail Security Logs:**

console -f -s Security

* **Follow Security Audit Logs:**

ausearch -f /var/log/audit -w 10

**Accessing Security Events from System Logs** 1. **Open Console.app:** - Go to Applications > Utilities > Console.app. 2. **Filter for Security Events:** - Click on the filter icon (funnel) in the top-right corner. - Enter "securityd" in the filter field and press Return. **Exporting Security Event Information** 1. **Go to Console.app Preferences:** - In the Console menu bar, click on "Console" > "Preferences". - In the "Logs" section, select "System.log." 2. **Export Logs:** - Click on the gear icon in the bottom-left corner and select "Export." - Choose the location and filename for the exported logs. Ensure the file extension is ".log." 3. **Use grep to Filter Exported Logs:** - Open Terminal.app and change the directory to the location where the logs were exported. - Run the following command to filter the logs for security events:

   grep -i "securityd" [filename].log > security_events.log
   

**Additional Notes:** * **securityd:** This is the main security logging facility on macOS. It logs all security-related events, including authentication, authorization, system configuration changes, and more. * **Console.app:** Console is a built-in macOS utility used to view and manage system logs. * **grep:** grep is a command-line utility used to search for patterns in text files. * **Format of Exported Logs:** The logs exported from Console.app will be in plain text format. * **Time Zone Considerations:** Ensure that the time zone settings on your Mac align with the timestamps in the logs, as they are stored in UTC.

**Accessing System Logs** 1. Open Terminal (Applications > Utilities > Terminal) 2. Type the following command to list all available log types:

logger --info --stderr

**Filtering System Logs for Security Events** 1. To filter the logs for security events, use the `security` keyword:

logger --info --stderr | grep security

**Exporting Security Event Logs** **Using the `log` Command** 1. Capture the security events into a text file using the `log` command:

log show --style syslog --source login -f

2. Save the output to a file using file redirection:

log show --style syslog --source login -f > security_log.txt

**Using the `syslog` Utility** 1. Pipe the filtered log output to the `syslog` utility to save it to a file:

logger --info --stderr | grep security | syslog -F security_log.txt

**Manually Parsing Security Logs (Optional)** Once you have exported the security logs, you can manually parse them to extract specific information. Mac system logs follow the [syslog format](https://en.wikipedia.org/wiki/Syslog). Here are some common fields you may find: * **timestamp:** Time of the event * **facility:** Subsystem (e.g., `authpriv`, `syslog`) * **source:** Source process or application (e.g., `securityd`) * **priority:** Level of the message (e.g., `err`, `info`) * **message:** Description of the event **Tips:** * You can use regular expressions (grep, sed) to extract specific data from the log files. * Use different log sources (e.g., `authpriv`) to capture specific security events. * Consider using a SIEM or log analysis tool for more advanced monitoring and analysis.

Output

**Leveraging macOS System Logs to Access and Export Security Event Information with Built-in Binaries** **1. Collect Logs with `log show`**

log show --style syslog --predicate 'subsystem == "securityd"'

* This command displays logs from the `securityd` subsystem in syslog format. * Filter logs by specific categories using `--predicate`, e.g., `authd` or `authorization`. **2. Extract Event Data with `auditlogfmt`**

auditlogfmt -e -d 'event.code=="0","event.ident=="login"'

* Converts raw log data into human-readable format. * Uses `-e` to display events as JSON and `-d` to display only specific data (e.g., events with code "0" and ident "login"). **3. Filter Logs with `grep`**

log show --predicate 'subsystem == "securityd"' | grep audit_succeeded

* Filters logs for specific keywords (here, "audit_succeeded") after collecting logs. **4. Parse Events with `auditp`**

auditp -f TEXT -P date,uid,success,event,ticket 6091843248.903651.txt

* Parses audit events into a specified format (here, CSV). * Specify the input file (`6091843248.903651.txt`) which contains log data collected using `log show`. **5. Export Logs** To export logs to a file:

log show --style syslog --predicate 'subsystem == "securityd"' > ~/security_events.log

To export in JSON format:

log show --style json --predicate 'category == "securityd"' > ~/security_events.json

**Additional Notes:** * Consider using a SIEM (Security Information and Event Management) tool for more comprehensive log analysis and security event monitoring. * Logs can also be collected and parsed using other tools like `syslog`, `awk`, or `bash` scripting. * Ensure you have sufficient permissions to access security logs (e.g., run commands as root).
