Social media is a blessing and a curse. It assists you in stay on touch with others but can also leak a lot of data and increase your vulnerability to breaches. Accordingly, remove any old accounts you don’t need to reduce risk.
Also try not to post information on social networks that might make you vulnerable, such as your address or information about your schedule or routine. If your social connections post information about you, make sure the combined information is not more than you would be comfortable with strangers knowing. Also be considerate when posting information, including photos, about your own social contacts.
