Protection Tips:
- Vet vendors for cybersecurity practices.
- Use encryption and access controls for shared data.
- Monitor vendor activity closely.
2.8 Zero-Day Exploits
Zero-day vulnerabilities are software flaws unknown to developers. Attackers exploit these vulnerabilities before patches are available. In 2025, the growing complexity of software will increase the frequency of zero-day exploits.
Protection Tips:
- Implement a robust patch management process.
- Use intrusion detection and threat intelligence tools.
- Limit system privileges to reduce potential damage.
2.9 Insider Threats
Insider threats involve employees or contractors misusing access, whether intentionally or accidentally. Data theft, sabotage, and policy violations fall into this category.
