Administrative Users

·
Dedicate and limit the number of computers used to complete CustomerLink
transactions; do not allow Internet browsing or e-mail exchange and ensure these
computers are equipped with latest versions and patches of both anti-virus and
anti-spyware software.
·
Delete online user IDs as part of the exit procedure when employees leave your
company.

Assign dual system administrators for online cash management services.

Use multiple approvals for monetary transactions and require separate entry and
approval users.
·
Establish transaction dollar limits for employees who initiate and approve
online payments such as ACH batches, wire transfers, and account transfers.
Tips to Avoid Phishing, Spyware and Malware
·
Do not open e-mail from unknown sources.
Be suspicious of e-mails purporting to be from a financial institution,
government department, or other agency requesting account information, account
verification, or banking access credentials such as usernames, passwords, PIN
codes, and similar information. Opening
file attachments or clicking on web links in suspicious e-mails could expose
your system to malicious code that could hijack your computer.
·
Never respond to a suspicious e-mail or click on any hyperlink embedded in a
suspicious e-mail. Call the purported source if you are unsure who sent an
e-mail.
·
If an e-mail claiming to be from your financial organization seems suspicious,
checking with your financial organization may be appropriate.
·
Install anti-virus and spyware detection software on all computer systems. Free
software may not provide protection against the latest threats compared with an
industry standard product.
Update all of your computers regularly with the latest versions and patches of
both anti-virus and anti-spyware software.
·
Ensure computers are patched regularly, particularly operating system and key
application with security patches.
·
Install a dedicated, actively managed firewall, especially if using a broadband
or dedicated connection to the Internet, such as DSL or cable. A firewall
limits the potential for unauthorized access to your network and computers.
Check your settings and select, at least, a medium level of security for your
browsers.
Clear the browser cache before starting an online banking session in order to
eliminate copies of Web pages that have been stored on the hard drive. How the
cache is cleared depends on the browser and version you are using. This function
is generally found in the browser's preferences menu.
Tips for Wireless Network Management
Wireless networks can provide an unintended
open door to your business network. Unless a valid business reason exists for
wireless network use, it is recommended that all wireless networks be disabled.
If a wireless network is to be used for legitimate business purposes, it is
recommended that wireless networks be secured as follows:
Change the wireless network hardware (router /access point) administrative
password from the factory default to a complex password. Save the password in a
secure location as it will be needed to make future changes to the device.
Disable remote administration of the wireless network hardware (router / access
point).
If possible, disable broadcasting the network SSID.
If your device offers WPA encryption, secure your wireless network by enabling
WPA encryption of the wireless network. If your device does not support WPA
encryption, enable WEP encryption.
If only known computers will access the wireless network, consider enabling MAC
filtering on the network hardware. Every computer network card is assigned a
unique MAC address. MAC filtering will only allow computers with permitted MAC
addresses access to the wireless network.
