What are some best practices for administrators and employees to secure transactions?

Do not share passwords, PIN, security tokens or any other account credentials. That includes reusing the same credentials elsewhere or sharing them with another person. Keep them secure.

Always use strong and unique passwords that are not easily guessable. An 8 characters or longer, random password that contains a combination of upper and lower case letters, numbers and symbols is much harder to break.

Review account transactions daily and reconcile frequently.

Avoid using public computers to access your account—even if additional security measures have been taken.

Practice security principles of least privilege and separation of duties. BILL provides granular, role based access control capabilities in the product. Use them to carefully grant and monitor access. Grant minimal access needed for employees to do the assigned job duties. Promptly remove the access when no longer needed. Assign different roles to different employees so that a single person alone can not compromise the transaction workflow.

Building a security culture where everyone understands their part in keeping an organization secure goes a long way. Train everyone in the company on best practices in information security, not just financial personnel. Identify regular opportunities to routinely discuss security best practices, such as staff meetings or other group check-ins.

Set up Multi-Factor Authentication to help further protect your account from unauthorized log-ins.

What are the best practices for administrators?

Install reputable anti-virus and anti-malware software and update it frequently. Most modern software updates automatically.

Keep operating systems, browser, and email patches up to date.

Keep your web browser software up to date by regularly installing the most recent version.

Use reputable network and desktop firewall solutions.

Require and monitor that users sign off their computer or employ a lock screen when not in use.

Consider disabling CD, DVD and USB drives on all computers where these drives are not needed.

What are the best practices for accountants and employees?

Do not click on links or attachments in an email that seem suspicious, and do not reply to it. Forward all suspicious emails directly to your IT and/or Risk team.

Be suspicious of requests for secrecy or pressure to take action quickly.

Watch for bogus email messages disguised to appear as authentic. Fraudsters commonly spoof legitimate email domains with ones that look similar (e.g., name@busines.com or name@business.net instead of name@business.com).

Hover over an email address to ensure it isn’t being masked as something it’s not.
