Potential Security Risks
- 22: Used for SSH (Secure Shell) access, which can be targeted for unauthorized access.
- 514: Commonly used for syslog; poor configurations can expose logs to attackers.
- 9000 & 9200: Often used by databases like Elasticsearch, which if misconfigured,
can allow unauthorized access.
- 5060 & 5061: Used for SIP (Session Initiation Protocol); potential for VoIP
vulnerabilities.
- 135, 139, 445: Commonly associated with Windows file and printer sharing; well-known
for exploitation (e.g., SMB vulnerabilities).
- 3306: MySQL database port; if exposed, can lead to database leaks or attacks.
Safe Ports
- 80: HTTP; widely used but can be vulnerable if not secured.
- 443: HTTPS; generally secure when properly configured.
- 515, 631, 9100: Printing services; less commonly targeted but still require attention.
- 2020, 8000, 8080, 8089: These are used for various web services and applications;
security is dependent on service configuration.
Conclusion
Given the mix of commonly used and high-risk ports, immediate actions should include
assessing security configurations, implementing access controls, and considering regular vulnerability
scanning and monitoring. Prioritize securing ports that are frequently targeted, like 22
and 445, and ensure that secure protocols like SSH and HTTPS are enforced.
