You may not pay attention to the URL or site address, after you do a search or click on a link from one site to another, but you need to start. Before you log in or enter any information on a site, you need to make sure that the address starts with https:// – and not http://, like https://Infoportal.data-command.com. The “s” at the end makes all the difference in the world! Once you get to a site, look for the lock in the address bar, next to the site URL. This indicate that the site is protected by TLS formerly SSL.
If the lock is showing, then you are probably okay. But it never hurts to make sure the certificate is valid. Most newer browsers will tell you if they are not.
