Tanker Management and Self Assessment sets safety and cyber risk rules for ship operators. Engineering teams meet tmsa compliance by logging system commands and locking down database permissions.
Maritime operators run shore apps and vessel software to manage cargo and crew schedules. Industry inspectors check these digital systems during routine vessel and office audits. If an operator fails a review, charterers may refuse to hire their ships. Security managers must prove that only approved staff can run changes on production servers.
Scope and audit evidence for tmsa compliance
The Oil Companies International Marine Forum created this framework to measure safety management systems. Element thirteen of the guide focuses on maritime cyber security and data protection. It requires ship operators to protect both office networks and onboard control systems. Auditors look for clear rules that govern how engineers log in to critical databases.
During an assessment, inspectors ask for proof of strong access controls across all environments. Teams must show that each engineer uses a unique identity rather than shared keys. Auditors also ask for complete logs of every command run against production data. These records must show who ran a query, when it ran, and who approved it.
Many maritime firms align these controls with broader frameworks like ISO 27001 or SOC 2. When teams collect command logs for those standards, they also satisfy maritime audit checks. Inspectors want to see that managers review role permissions on a regular schedule. Clear log records make it easy to pass these reviews without weeks of manual work.
Why identity rules need command logs and data masking
Setting up single sign-on and role groups is a great first step for security. Still, static role groups do not show what an engineer does after logging in. A developer with valid database credentials might still run a risky update by mistake. Periodic role reviews only show who had permissions, not which queries they actually ran.
Runtime command logs close this gap by recording every action at the query level. Security teams can see the exact SQL statements or shell commands run during maintenance. Teams can also add approval steps before someone runs a sensitive command in production. This creates a clean audit trail that proves tight control over shore and ship systems.

Maritime databases also store crew records that fall under strict privacy laws like GDPR. When engineers query these tables to fix a bug, results may hold personal data. Response masking rewrites matched fields like emails, phone numbers, card numbers, or national IDs. Engineers can fix the app issue while the system protects crew privacy in query results.
Building a practical audit workflow for maritime systems
Security managers should map every critical database and server across shore and vessel networks. Next, teams should remove shared admin accounts and link all logins to an identity provider. Every production session should leave a detailed log of the commands that ran. Managers should review these logs each month to verify that rules work as planned.
Check database and API queries on the wire
Identity tools, roles, and network rules decide who opens a session. Setup alone cannot check what each query does or mask sensitive values in a response once a session starts. When workflows touch Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, or internal HTTP APIs, hoop.dev runs beside those services as an open-source proxy, a sidecar for your Postgres or API. It inspects requests coming in and results going back on the wire.
Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run. On responses, hoop.dev data masking rewrites matched sensitive values in memory. Furthermore, hoop.dev holds SOC 2 Type II, is MIT licensed, and writes every query and decision to an audit trail that generates evidence for HIPAA, GDPR, and PCI DSS. See the source on GitHub.
Frequently asked questions
What part of the TMSA framework covers IT and engineering systems?
Element thirteen covers cyber security across office networks and onboard vessel systems. It requires operators to manage user permissions, protect sensitive data, and log system activity.
What audit evidence do maritime inspectors ask engineering teams to provide?
Inspectors ask for user permission lists, approval records for production changes, and command logs. These records prove that only authorized staff ran updates on critical operational databases.
How does response masking help maritime teams protect crew data?
Masking rewrites emails, phone numbers, card numbers, and national IDs in query results. This lets engineers fix database issues while keeping crew personal data safe during support work.
Short role checks help teams work fast. Simple rules make each review clear. Good logs keep every team safe. Scoped keys stop bad changes early.
Teams test new role rules in staging first. Clear owner lists speed up each audit. Small role scopes cut down on risk. Regular log checks catch drift right away.
