How the Net Works
This numerical label uniquely identifies every device connected to the Internet.
What is an IP address?
This device forwards data across networks.
What is a router?
Data that relates to or describes an individual—such as a full name, birthdate, fingerprint, or location data—is known as this.
What is PII (Personally Identifiable Information)?
The process of encoding a plain text message into a secret format so only authorized parties can read it.
What is encryption?
In 2017, Equifax learned their lesson on why this method of data protection, which involves improving how your computer or a program operates, is so important.
What is updating your software?
Often called the "phonebook of the Internet," this system translates domain names like “google.com” into numeric IP addresses.
What is the DNS (Domain Name System)?
The maximum amount of data that can be sent over a network connection in a fixed amount of time.
What is bandwidth?
A deceptive social engineering trick where attackers attempt to bait users into revealing sensitive credentials like passwords or banking info.
What is phishing?
This method of encoding a message shifts each letter in the alphabet by a set number. Don't be afraid to take a stab at it!
What is Caesar’s cipher?
What is computer virus scanning software (or anti-virus software)?
Before data travels across the Internet, it is broken down into these small chunks to be transmitted and reassembled at the destination.
What are packets?
The sequence of connections that data takes to travel all the way from a sender to a receiver.
What is a path?
This kind of malicious software records everything a user types on their device to steal secret credentials.
What is keylogging?
This kind of encryption system uses one shared secret key for both encrypting and decrypting messages.
What is symmetric key encryption?
This account verification method requires evidence from at least two categories: something you know, something you possess/have, or something you are.
What is MFA (Multi-Factor Authentication)?
This protocol assigns unique addresses to connected devices so data messages know where to go.
What is IP (Internet Protocol)?
A network maintains this property when it can continue functioning normally even if individual connections or components fail.
What is fault tolerant?
Bad actors use this device to connect to a secure network, giving them unauthorized access to network traffic.
What is a rogue access point?
Hackers attempt this when they try to decode a secret message without knowing all the details of the cipher.
What is cracking an encryption?
When inputting personal information using the World Wide Web, this protocol, which uses SSL/TLS to protect communication by encrypting data, ensures you have a secure connection.
What is HTTPS (Hypertext Transfer Protocol Secure)?
This transport protocol numbers packets and performs error-checking to guarantee every packet is received and in proper order.
What is TCP (Transmission Control Protocol)?
Adding extra components or multiple paths to a network creates this feature, which ensures data can reroute if a connection goes down.
What is redundancy?
This broad term refers to software created specifically to damage a computing system or take unauthorized partial control of its operation.
What is malware?
What is asymmetric (or public key) encryption?
These trusted third-party organizations issue digital credentials that help verify a secure connection reaches the intended website and not a fake one.
What are certificate authorities?
