Security Best Practices

We offer these guidelines to help you protect against transactional and online fraud. When you consider the potential financial losses, business disruption, recovery time, and costs associated with fraud, implementing these security best practices and due diligence upfront is well worth the effort.

With the increase of cybercrime and fraud scams, you cannot rely on a single system or service to effectively mitigate against transactional and online fraud risks. We urge our customers to adopt many risk mitigation best practices such as multiple layers of security, refinement of operational procedures and system controls, and installation of IBM® Security Trusteer Rapport® and other security software to achieve higher levels of security protection.

When it comes to fraud and cybercrime, you have the tools and responsibility to prevent losses to your business. Please consider the recommended guidelines below, as well as all current and new tools that become available to help safeguard and strengthen your business against financial fraud.


Verify payment information with sender when notified via email for payment

Call the email originator at a previously documented number (provided outside of the email) to confirm payment instructions are accurate. Fraudsters send emails to individuals and businesses from an email account that is disguised to be from a known vendor. Fraudsters may also alter the original email instructions, causing the funds to be rerouted to the fraudster instead of the intended vendor. Be cautious of emails that press urgency and secrecy. Look for slight variations in email addresses and subtle discrepancies.


Install IBM Security Trusteer Rapport

We provide this complimentary software to help you combat financial fraud. Trusteer Rapport’s innovative technology picks up where conventional security software falls short. From the moment it is installed, Trusteer Rapport protects the customer’s device and mitigates financial malware infections. It provides instant PC and Mac anti-fraud protection against financial malware, as well as phishing attacks.


Implement dual control (Bank’s Standard Settings) to initiate and release payment transactions on separate machines

Having a minimum of two persons involved in a transaction ensures accuracy, and adds a layer of complexity to keep fraudsters and internal employees from compromising your accounts.


Establish appropriate company and/or user transaction dollar limits

This will help limit the exposure in case of unauthorized payment attempts.


Never disclose or write down usernames, passwords, and token passcodes

Never disclose these types of sensitive information to another party via phone, email, text or chat. Bank personnel will never ask for passwords and token information.


Review full details of the payment transaction before release


Promptly review ACH, Wire Transfers, and other transaction notifications


Set up email alerts for ACH, Wire Transfer, and balance thresholds

Email alerts will help bring your attention to unauthorized transactions and unusual changes to your account balance.


Reconcile account activities daily


Regularly review user access

Allocate permissions and access to staff on an “as needed” basis to manage risk and limit over-privileged users. Promptly deactivate employee access when it is no longer needed.

Trusteer Rapport

Always update to current versions of firewall/antivirus software and related technologies (operating systems, browsers, and security suites) and scan on a regular basis.

Security updates patch vulnerabilities that may be exploited by malware and help keep users and their data safer. You are only as protected as your system and security software updates.


Dedicate a computer with restricted internet access to conduct financial activities (accounting, online banking, and outgoing ACH/Wire transfers)

Restricting web surfing, email, and other access of the computer will help limit the exposure and possibility of infections.


Enhance your password security by making your passwords more complex and use different passwords for different accounts and systems

Try combining random words together for easy remembering. Incorporate upper and lower case letters, numbers, and symbols. Do not use birthdays, family names, or telephone numbers.


Consider using false answers for security authentication questions

Fraudsters do their research before taking action on their target. They can gather general public knowledge and formulate detailed information. Thus using mixed or untrue information will help strengthen your accounts’ security.


Do not open unrecognized email and open familiar emails with caution. You can never tell who is truly behind the email


Email is not a secure medium of communication. Only general inquiries should be sent via email. Encrypt sensitive data before sending

Do not respond to any messages requesting the following information:

  1. Online banking credentials
  2. Personal information (social security number, business TIN, mother’s maiden name, and etc.)
  3. Bank account, credit card or ATM/debit card numbers


Disable ‘AutoComplete’ or other memorize password functions on browsers


Avoid downloading attachments or clicking on embedded links in emails or websites whether you are or are not familiar with them


Log off when you’ve finished your banking or if leaving your computer unattended


Restrict access to computer functions, including software installations, USB, and CD Burner


Use HTTPS websites


Avoid connecting to unsecure Wi-Fi

Unsecure internet networks may allow fraudsters to intervene and steal information as it is being transmitted. Review your mobile device’s setting to disable ‘Auto Connect’ feature to avoid connecting to unknown/unverified networks.


Avoid use of public computers and unsecure internet connection

Utilize Positive Pay Service

Utilize ACH Blocks & Filters

You can either block all incoming debits with ACH blocks, or designate a list of authorized debits/credits with filters. If the ACH originator is not on the authorized list you provide, we will return unauthorized transactions.


Utilize dual control throughout your check stock storage, printing, issuing, signing, and dispatching


Audit and destroy old inventory


Customize your check stock with security features

Customizing your check with a watermark, chemical resistance, fluorescent fibers, bleach-reactive brown stain, photocopy void pantograph, security ink message, micro-printing, or holographic marker helps prevent check altering and counterfeits.
