3. Regular updates and security patches
Open-source tools often have rapidly growing communities, but they do not always provide professional support. Regular maintenance (patch management) is essential to prevent the exploitation of known vulnerabilities.
What to check:
- How frequently the project releases new versions
- Whether it has a clear security policy and a registry of known vulnerabilities (CVE)
- Whether upgrades can be automated (e.g., via Docker)
Example:
PostgreSQL regularly releases security updates – failing to apply them can lead to serious issues such as SQL injection vulnerabilities.
