Set aside time each month to take stock of your online accounts. This process could include closely reviewing your credit card statements - particularly following the holiday season - for suspicious transactions; closing down online accounts you no longer use; and changing a handful of passwords to make them stronger.
Make this part of your regular routine. Don't assume that other companies are going to do security right on your behalf. We have to take our own responsibility to do a little more. All these things will help you be more resilient against future breaches and attacks.
