• Review & Re-Evaluate The Procedures Regularly

• Security Procedures Should Evolve. Why?

ISAWWATraining



1. DO NOT USE THE TELEMETRY COMPUTER FOR NON-TELEMETRY PURPOSES!

2. INSTALL SECURITY UPDATES FROM THE OPERATING SYSTEM VENDOR (EG MICROSOFT) FREQUENTLY AND REGULARLY.

3. DO NOT INSTALL 3RD PARTY SOFTWARE ON THE TELEMETRY COMPUTER. DO NOT ADD EXTRA HARDWARE TO THE COMPUTER.

DO NOT PLUG USB MEMORY STICKS INTO THE COMPUTER.

4. NEVER REVEAL A USERNAME/PASSWORD PAIR TO ANOTHER PERSON.

5. IF A USERNAME/PASSWORD PAIR IS SUSPECTED TO HAVE BEEN COMPROMISED, OR IF AN EMPLOYEE WHO HAD ACCESS TO

THE SYSTEM IS TERMINATED – THEN DELETE HIS/HER USERNAME/PASSWORD FROM THE SYSTEM IMMEDIATELY... AND UNTIL THIS ACTION IS TAKEN, DISCONNECT THE SCADA SYSTEM FROM THE INTERNET OR TELEPHONE LINE IMMEDIATELY.

6. DO NOT ADD EXTRA USER ACCOUNTS TO THE COMPUTER’S OPERATING SYSTEM.

7. ONLY PROVIDE TELEMETRY SYSTEM ACCESS TO PERSONNEL WHOSE JOB REQUIRES IT; AND ONLY PROVIDE THE MINIMUM

FUNCTIONALITY THAT EACH PERSON REQUIRES.

8. REGULARLY REVIEW THE ACCESS & ACTIVITY LOGS.

9. IF UNCERTAIN, CALL YOUR TELEMETRY VENDOR OR CONSULTANT FOR A CONSULTATION.

10. IF SECURITY TELEMETRY SECURITY PROCEDURES ARE NOT BEING FOLLOWED, THEN DISCONNECT FROM THE INTERNET!
