TECH TALK WITH JOHN RUDY: Additional Security Issues


tech talk

In August,  I talked about the importance of proper passwords for your computer life and stressed that using the same password for everything risks that someone able to find it has access to your whole life.  I also said that simple passwords like your spouse’s first name or the name of your first pet are too easy to crack.   Thanks to Facebook and easy hacker tools, data about you is readily available so you have to come up with complex passwords at least 8 characters long.  So how can you remember all this?  The first step is to get them off paper and into a computer file, like an Excel spreadsheet.  But don’t name the spreadsheet “passwords” and put it into a folder called “important computer information”.

Any file on your computer can be encrypted.  Yes, I know that is one more password to remember.  Depending on the version of Microsoft Office you have, there are somewhat different processes, and you can Google to find them.  For Word 2010 or Excel 2010, click on FILE, then on INFO, then on PROTECT DOCUMENT and you can supply a password.

IMPORTANT: practice this on some test documents until you are sure you remember just how to do it.

Quite a few companies sell password Managers (protected by a password) where you can store all your passwords and information about the passwords.  These managers make it easy to retrieve the password you want from a variety of devices (desktop, laptop, smartphone, and tablet).  Here is a review from PC Magazine of the best password Managers in 2016.  There is a lot of interesting material in this article and it is interesting to me that the PW Managers most talked about a couple of years ago are no longer on this list.,2817,2407168,00.asp

To switch topics …

I received a note asking me about the unsubscribe link found at the bottom of many emails sent by commercial companies. The question (reminds me of Marathon Man) was “Is it safe?”  Well, that depends.  If you are certain that the email is from a legitimate company, then the unsubscribe is a perfect way to stop getting their email.  But sometimes, the email is unsolicited and might be what is called phishing.  It looks like it is from a legitimate company but is not, and the unsubscribe is a trick to get you to click on to a link that will import malware to your computer.  But let’s say that the email is from a legitimate source.  Then hitting the unsubscribe tells the sender that you are real, and that may give it information about you that is tucked into your response, setting you up for other advertising from complicit companies.  I recently got an email containing an unsubscribe link.  The source address on it was  I suspect it is okay, but anyone can buy an address like that.  The UNO home page is so I would have been more comfortable if I had received the email from that url or a subset of that url.

Next month’s talk will be on travel, but before we get to that, here is a reminder: Take out all the credit cards and other stuff (like SS card and license) in your wallet and place it on your printer.  Take pictures of both sides. Then take a picture of your passport.  Put these pictures in your safe deposit box and another safe place in your house so if your wallet is stolen you know what the crooks have.  Why not limit it to your safe deposit box?  Because if the theft is Saturday at 4pm you won’t be able to get to the safe deposit box until Monday morning.
