Maritime Infrastructure Is Under Attack — Are You Prepared?
Super Hero IT Solutions | Cybersecurity & Compliance for Critical Infrastructure
The Rising Threat Where IT Meets OT
Add to the ever increasing list of businesses, ports, shipping operators, and maritime facilities are increasingly targeted by cyberattacks. As legacy Operational Technology (OT) systems connect with modern IT networks, new vulnerabilities appear—opening the door to ransomware, credential theft, and nation‑state threats.
At Super Hero IT Solutions, we deploy high‑impact, low‑disruption improvements that reduce risk fast and align with compliance mandates.
Fast, High‑Impact Security Wins
These quick wins support the U.S. Coast Guard Final Rule and frameworks like CMMC Level 2 and NIST 800‑171.
- > Strengthen password policies across IT & OT
- > Enforce Multifactor Authentication (MFA)
- > Eliminate shared or over‑privileged accounts
- > Apply the principle of least privilege
- > Lock out accounts after repeated failed attempts
- > Separate credentials for critical systems
- > Revoke access immediately when staff depart
Why Access Control Still Matters
Most breaches start with a single compromised account. Phishing, password reuse, and shared logins are still the easiest way in. Strong access control is your first line of defense—without it, even the best perimeter tools can’t keep attackers out.
What the Coast Guard Final Rule Requires
- > Enable automatic account lockout after repeated failed logins across password‑protected IT systems
- > Change default passwords (or apply compensating controls) before using any IT or OT system
- > Maintain minimum password strength on all IT and OT systems capable of password protection
- > Implement multifactor authentication (MFA) on password‑protected IT and remotely accessible OT systems
- > Apply least privilege to administrator and privileged accounts on both IT and OT systems
- > Maintain separate user credentials on critical IT and OT systems
- > Remove or revoke user credentials immediately when a user leaves the organization
Quick Win #1: Fix Password Practices Today
Default or shared passwords like admin123 on critical systems are open invitations to attackers. Start here:
- > Enforce strong passwords (12+ chars, mixed case, numbers, symbols)
- > Eliminate password reuse—especially between IT and OT systems
- > Immediately change all default credentials
- > Deploy a secure password manager to ease adoption
- > Enable automatic lockout after multiple failed attempts and periods of inactivity
Compliance Tip: Documented password policies and evidence of enforcement help demonstrate compliance with the Coast Guard Final Rule and NIST 800‑171 controls 3.1.1 and 3.5.7.
