  5. Backup Key Information

1. Help Protect Sensitive Information

  • Never give out a PIN, SSN, personal or banking information in response to an email.
  • Emails are not a 100% secure method to send information. Do not include any account information or identity information in a non-secure email.
  • Use “strong” passwords with at least 8 characters that include a combination of mixed case letters, symbols and numbers.
  • Don’t share passwords.
  • Change passwords frequently.
  • Avoid using an automatic login feature that saves your username and password.

2. Help Defend Computers Against Attacks

  • Keep computer operating systems and applications up-to-date on workstations and servers.
  • Install AntiVirus software and desktop firewalls to limit unauthorized network access.
  • Download and install Trusteer, Inc’s free Rapport security software from The Commerce Bank of Washington website.
  • Consider using dedicated computers for business online banking. Do not use public or unsecured computers.
  • Do not open emails from unknown sources. Be suspicious of emails claiming to be from a financial institution. Opening file attachments or clicking on web links could expose your system to malicious code that could hijack your computer.
  • Do not install software from unknown sources.

3. Implement Operational Safeguards

  • Separate financial duties, so that one individual does not handle all aspects of the company’s online transactions.
  • Enable dual approval control for all money movement and transactions, including cash management services.
  • Establish transaction dollar limits for initiation, approval, and release of money transfers.
  • Take advantage of available alerts. Receive notification when balances are low, transfers are made, passwords are changed and email addresses are updated.
  • Reconcile accounts daily and review transactions for validity.
  • Delete online user IDs, as part of the exit procedure, when employees leave your business.
  • Utilize check stock safety features, such as: watermarks, thermo chromatic ink, high resolution borders, etc.

4. Never Be Too Cautious

  • Never leave your computer unattended. Install screensaver timeouts, so your computer locks automatically after a specified time range.
  • Encrypt sensitive data.
  • Dispose of computers, mobile devices, and documents with secure information in a secure manner.
  • If you suspect fraudulent activity, call your Customer Service Representative as soon as possible at 206-292-3900.

5. Backup Key Information

  • In the event of a hardware or software failure due to fraud, ensure computers and servers are being backed up to protect important data.
