Security Measures

Protect Your Passwords

Make your passwords as obscure or abstract as possible. Avoid obvious numbers and words, such as a maiden name, birth date, or an anniversary, which would be easy to guess. Never divulge your passwords to anyone, including family or friends.

Don't E-Mail Personal or Health Data

Most email is not secure or encrypted and should not be trusted to send personal or financial information. Email you send from within Member Central (after you have logged in) on, however, is encrypted. This is the most secure way to contact us online. Otherwise, call to speak to a representative.

Steps Blue Cross Blue Shield is taking to Protect You

  • Customer Access to Account Information
    No matter how you contact Blue Cross Blue Shield of Massachusetts—online, or by phone—we verify your identity before granting you access to your information.

  • Timed Log-Off automatically logs you off after an extended period of inactivity. This reduces the risk that others could access your information from your unattended computer.

  • Firewalls
    To block unauthorized access, all our computer systems are protected by firewalls, electronic barriers that prevent unauthorized access to our networks.


Blue Cross Blue Shield of Massachusetts employs some of the strongest methods of encryption commercially available today. All online activity involving personal or sensitive information is encrypted from the point it leaves your computer until it enters our systems. For your general online security, be sure you see the letter "s" at the end of "https" at the beginning of the URL address before entering any sensitive information, indicating the site is secure (e.g., ""). Similarly, another indication that a website is secure is a padlock icon in the lower right corner of your browser.


Protect Yourself from Phishing Scams

Phishing is the mass e-mailing of messages that falsely cl aim to come from a legitimate business. These messages often provide links to phony Web sites, where you are asked to supply personal information such as passwords, credit card numbers, Social Security numbers, or bank account numbers.

Finally, know that Blue Cross Blue Shield of Massachusetts will never e-mail you requesting that you confirm your personal information or password.

Never enter personal information unless you are sure the website is legitimate. You should also be certain the site is encrypted. Look for the letter "s" at the end of "https" at the beginning of the URL address. An example of such a URL address is "" This ensures that the site is running in secure mode.

How to Recognize Phishing E-Mail

Phishing messages have evolved drastically over the last year, and they are often difficult to recognize. The creators now incorporate realistic company logos and graphics, provide links to the real company's privacy policies, and even include "legal disclaimer language" at the bottom.

To help determine if email is part of a phishing scam, ask yourself the following:

  • Do I have a relationship with this company?

  • Would I expect this company to contact me this way?

  • Would I expect this company to use this tone or make this request?

If you are at all unsure, contact the company by phone.

How to Protect Yourself from Malware and Viruses

Common types of malware are:


Software that may be installed on a computer without the user's consent to monitor use, send pop-up ads, redirect a computer to certain websites, or record keystrokes, which could lead to identity theft.


Software disguised to perform one legitimate action, but actually performs another often malicious one such as enabling unauthorized people to access the affected computer through a backdoor and sometimes to send spam from it.


A program that is attached to a file or program so it can spread from one computer to another often without the user's knowledge — often through an e-mail attachment. Some viruses are programmed to be extremely damaging, while others are programmed to have annoying effects.

Steps you can take to protect yourself from these types of dangers are:

  • Create a hard to guess password and make it unique

  • Change your password periodically

  • Keep your browser and Operating System up to date

  • Update your anti-virus software regularly

  • Use a personal firewall
