2. Use a Strong Password. Make sure that, first & foremost, you are password protecting your desktop and mobile devices. Secondly, make sure that you are using a strong password. I know, remembering passwords, especially these days when everything requires a password can be difficult. For non-critical sites such as emails, subscriptions, newsletters, etc. I have been using Lastpass (www.lastpass.com) for the last 3 years. This is a great program as it can be installed on almost all browsers, automatically captures site information & login information when you sign up for any service, rates the strength of your password and helps generate strong passwords. There are many ways to generate strong passwords, the simplest one I have found is to make sure that it is at-least 8-10 characters, contains alphabets, numbers & signs and has at-least 2 Upper cases.
3. Update Your Browser & Use Safe Sites. Make sure that you are using the most recent version of your browser and that its "Safe Search" is turned on. These days, almost all the popular browsers (IE, Chrome, Firefox, Safari, etc.) have their safe search mode turned on by default. This function will warn you if any site that you are visiting is not safe or contains malware.
4. Don't Clicking on links that you don't know where they will take you. Quite often we receive emails or pop-ups that offer links to other sites. If you are not sure or have even an iota of doubt as to the purpose of the link, do not click on it.
5. Do Your Due Diligence. As users, it is our responsibility that we are always alert when browsing to make sure that the sites that we are visiting, the links that we are clicking on or the password / username that we are creating are strong & safe. Do not post your SSN number or other personal details just because someone is asking for it.
