Exposed Services Audit
Audit of publicly exposed services, open ports, unnecessary listeners and attack surface on Linux servers.
What We Check
An Exposed Services Audit maps the attack surface of your Linux server by identifying every service reachable from the public internet and evaluating whether that exposure is necessary and secure.
Our audit covers:
- Port scan analysis — full TCP and targeted UDP scan to identify all listening services on public interfaces
- Service identification — fingerprinting of running services behind each open port
- Version detection — software versions exposed to determine patch status and known vulnerability exposure
- Unnecessary exposure — services that should not be public (database ports, admin panels, monitoring dashboards, backup interfaces)
- Database ports — MySQL, PostgreSQL, Redis, MongoDB, Elasticsearch exposed without network-level restriction
- Admin panels — phpMyAdmin, Webmin, cPanel, Plesk, custom admin interfaces accessible from the internet
- Development tools left running — debug endpoints, staging environments, test services, profilers, package managers
- Default configurations — services running on default ports with default credentials or without authentication
- Banner and header exposure — software version disclosure in service banners and HTTP headers
- Internal service leakage — memcached, Docker API, message queues or other backend services reachable externally
Why Exposed Services Matter
Every publicly accessible service is a potential entry point. Databases exposed to the internet are routinely scanned and exploited within hours. Admin panels with default credentials are a primary target. Development tools left running in production provide detailed internal information to attackers.
Reducing your attack surface to only the services that must be public is one of the most effective security improvements you can make. An exposed services audit gives you a clear view of what is reachable and what should not be.
What You Receive
- A complete map of all publicly accessible services and ports
- Risk-rated findings for each unnecessary or insecure exposure
- Remediation guidance for each finding (firewall rules, bind address changes, service removal, access restrictions)
- Before/after comparison if a re-scan is requested after remediation
- Follow-up consultation to discuss findings and prioritize changes
