Most scripts in this project require root privileges to:

• Configure kernel parameters (/sys/block/zram*, /proc/sys/vm/*)
• Manage swap devices
• Load/unload kernel modules

Recommendations:

1. Review scripts before running with sudo
2. Use configuration files instead of command-line arguments for sensitive values
3. Run benchmarks in isolated environments when possible

All scripts use safe defaults:

• No destructive operations without explicit confirmation
• Graceful fallbacks when features are unavailable
• Logging of all configuration changes
• Backup creation before modifying system files

1. PID file race conditions: Daemon scripts use PID files which could theoretically be exploited. Mitigated by root-only permissions.

2. Temporary files: Some scripts create temporary files in /tmp. These are cleaned up on exit but could be targets during execution.

3. Loop devices: Writeback setup uses loop devices. Ensure backing files are on trusted filesystems.

If you discover a security vulnerability:

1. Do NOT open a public issue
2. Email the maintainers directly (see repository contact info)
3. Include:
   • Description of the vulnerability
   • Steps to reproduce
   • Potential impact
   • Suggested fix (if any)

We will respond within 48 hours and work with you to address the issue.

1. Verify downloads: Check release signatures when available
2. Review before running: Especially scripts from forks or PRs
3. Monitor system: Use the included monitoring tools to detect anomalies
4. Keep updated: Apply security updates to your kernel and this toolkit
5. Backup configurations: Before major changes to ZRAM setup
