How to Protect Yourself

Internet Security

Font Size 

The Middlefield Banking Company is taking advantage of the enormous potential offered by the Internet by making more and more of our products and services available "online". The Middlefield Banking Company uses a variety of technologies and techniques to secure its products and services. You can also enhance security and help control risks when using your personal computer or when conducting business online. Here are some of the steps you can take.

Online Security Guidance

Your Computer Security

  • Control physical access to your personal computer. Do what you can to prevent unauthorized persons from using your computer.
  • If you are using your computer and need to walk away from it for any reason, log off your online account or lock your workstation.
  • Select passwords that would be difficult for others to guess and change them frequently.
  • Do not give your passwords to anyone. Do not save passwords on your website or leave written notes with your password near your computer.
  • Report suspicious activity you notice relating to your computer or use of your computer to the appropriate parties and do so as quickly as possible. If you notice suspicious activity relating to accounts at The Middlefield Banking Company that you access online, promptly report that activity to your MB customer service representative.

Virus Management

  • Install virus management software on your computer and use it regularly.
  • Keep it up to date (i.e., latest signature files, product upgrades).
  • Be cautious when downloading and running programs, Java applets or ActiveX applets as they may contain unsecure data which cannot be filtered, for example, using firewall or anti-virus software.
  • Use extreme caution when opening Email received from unknown sources and pay special attention to any attachments. Do not launch or open an attachment from an unknown source. When in doubt...delete it without opening it.

PC Software

  • Understand and use the security features provided by your computer software, such as those included in many operating systems, browsers and word processing systems.
  • Ensure that your browser uses the strongest encryption available and be aware of the level of encryption used when you connect to various sites and applications. For example, the EasyLink Online Banking system currently requires the use of 128-bit encryption.
  • Use only software from reliable vendors.
  • Stay abreast of the latest release and patch levels of the computer software you use.

Encryption/Browser Check

Encryption is the scrambling of data into a code that is unreadable to anyone who does not have the key that deciphers it. Only you and The Middlefield Banking Company have the key to unlock your code. With EasyLink Online Banking, all your account information is protected by 128-bit encryption to maintain the privacy and confidentiality of your data. To take advantage of strong encryption technology, you will need to obtain a secure browser, one that supports 128-bit encryption.
