Having common sense and being able to use the internet works for me. I have never been scammed by an exchange or by trading, and though there are many exchanges out there that are clones of real sites and are used for phishing. When you're using an exchange, make sure the SSL certificate is authentic and make sure that the URL is correct with no misspellings- there are sites out there that have one or two misspelled letters, and some people I know have fallen victim to such sites.
For sites you're unsure about, search on this forum to make sure whatever exchange or service you are using is legitimate. I search on Google using the format "(Site Name) Bitcointalk" to find threads and posts from this forum, and clicking on a few threads from the results you find typically help out in deciding whether a service or exchange is legit or not.
If you're unsure how old a site is, doing a Whois search of the website can reveal when the domain was registered. Many scam websites have very recently registered domains and/or hidden whois information, and either of these is a huge red flag most of the time.

What about the cases where there are dangerous phishing apps or fake wallets on legit online stores?
