Basic Cybersecurity Terminologies
Exploring cybersecurity can feel overwhelming, but knowing basic terms is key. We’ll cover important ideas like networks, the internet, internet protocols, IP and MAC addresses, DNS, DHCP, routers, and bots.
Networks, Internet, and Internet Protocols
Networks and the internet are central to cybersecurity. A network connects devices like computers and smartphones. The internet links these networks worldwide, letting devices share information.
Internet protocols like IP and TCP set rules for sending data. They make sure data gets to the right place.
IP and MAC Addresses
Every network device has a unique IP address for online identification. Each device’s NIC also has a MAC address for local network communication.
Domain Name Servers (DNS) and DHCP
DNS servers translate domain names into IP addresses. This makes it easier to visit websites without remembering long numbers.
DHCP assigns IP addresses automatically when devices connect to a network. It makes setting up devices simpler and ensures each has a unique IP.
Routers and Bots
Routers connect networks and manage internet traffic. They help keep connections secure.
Bots are automated programs that can do tasks online without human help. While some bots are helpful, others can cause harm, like in DDoS attacks.
Common Types of Cyber Attacks
Cybersecurity is key in our digital world. It’s important to know the common cyber attacks to protect yourself and your data. These include DDoS attacks, password hacking, and phishing scams. The world of cyber threats is always changing.
Distributed Denial of Service (DDoS) Attacks
DDoS attacks happen when someone floods a website or server with traffic. This makes it hard for real users to get in. For businesses, these attacks can cause big problems, like downtime and losing money.
Man-in-the-Middle Attacks
In a man-in-the-middle attack, someone intercepts messages between two people. They can listen in or change the messages. This attack is sneaky and can happen without the people affected knowing.
Password Attacks
Password attacks try to guess or break your passwords. They use methods like dictionary attacks, brute-force attacks, and rainbow table attacks. These methods try many passwords or use pre-made lists of common passwords.
Email Attacks: Phishing and Spoofing
Phishing and spoofing are attacks that use email to trick people. They try to get you to share sensitive info or do something you shouldn’t. Phishing emails pretend to be from real places or people. Spoofing makes it look like an email came from someone else.
Knowing about these cyber attacks helps us protect ourselves and our data. It’s key for making good cybersecurity plans.
| Attack Type | Description | Impact |
|---|---|---|
| DDoS Attacks | Flooding a website or server with traffic to overwhelm its resources | Causes downtime and financial losses for businesses |
