What’s one of the most commonly used methods of verifying a download can be trusted?
Run a checksum or hashing total on the file
(a hash total is available from the trusted source most often)
How do you use a hashing total?
You compare the string available from the trusted source (MD5 or SHA256) to a hashing total generated on the downloaded file
On a Windows system, the PowerShell command _____ will generate a hash total for comparison with the hash value provided by the trusted source.
Get-FileHash
According to Microsoft, what is an untrusted source?

What is a secure connection?
encrypts network traffic before it is transmitted over a communication medium
What type of secure connections do web browsers provide for the requests it sends to web servers over an HTTPS link?
they apply SSL or TLS encryption for the requests to web servers
SSL/TLS provide what 3 layers of encryption for the web page transmitted back to the user?
- Encryption
- Authentication
- Integrity
What does encryption mean?
it keeps the data private
What does authentication mean?
ensures the data is from the same site the user requested it from
What does integrity mean?
ensures the data isn’t altered in transit
What’s another way besides SSL/TLS encryption to validate that a site is real/not a fake?
with a security certificate
Why is a security certificate another way to be secure?
the certificate itself can be verified (which validates and authenticates a site’s ownership and its domain name)
How do you view the security certificate for a website?
click the padlock icon on a browser’s address bar
What is a pop-up?
Generally a nuisance, an object that displays over the top of a web page (may or may not be associated with the page)
(some legit sites require pop-ups for the site to function)
Virtually all browsers have a setting for blocking….?
pop-ups

A browser saves what 2 types of data?
- caching data
- browsing data
What is caching data?

What is browsing data?
browser history, a historical record of the sites you’ve visited and downloaded during a period of time
(titles, URLs, time and date of the visit, data provided)
What does the Private Browsing Mode do?
It doesn’t record the user’s online activities or cache downloaded files
What don’t private browsers mask?
the identity of the user and in some cases like on a smartphone, records a small amount of browsing history
What is Sign-in/Browser data synchronization?
user coordinates browser software and settings between devices (like Firefox tabs open on PC and on phone)
Any action is duplicated on the other after both devices are synchronized
How do ad blockers work?
they remove coding from the downloaded web page file that would display the ad
