Cybersecurity for beginners
Before you start learning about cybersecurity, it’s important to know some basic terms. This part will cover network basics, internet protocols, IP and MAC addresses, DNS, DHCP, routers, and bots. Knowing these basics is key to understanding cybersecurity.
Network Basics and Internet Protocols
A network connects two or more computers. The internet links computers worldwide using routers and servers. Internet Protocols, like the Internet Protocol (IP), help manage data across the internet.
IP Addresses and MAC Addresses
An IP address is a unique number for devices on a network. It looks like a series of four numbers, like 168.192.10.3. A MAC address is also unique and shows up as a 12-digit number, like D8-FC-93-C5-A5-EO.
DNS and DHCP
DNS, or the Domain Name System, is like the internet’s phonebook. It changes domain names (like www.example.com) to IP addresses. DHCP, the Dynamic Host Configuration Protocol, gives IP addresses to devices automatically.
Routers and Bots
A router sends data to where it needs to go. Bots are programs that work without you knowing, doing things like sending emails or changing settings.
Learning these basic cybersecurity terms is a great start. Next, we’ll explore common cyber threats and attacks.
Common Cyber Threats and Attacks
In today’s digital world, cyber threats are more common than ever. Cybercriminals use many tactics to break into systems and get to sensitive info. Knowing about distributed denial of service (DDoS) attacks and man-in-the-middle attacks is key to fighting back.
Malware is a big threat, including viruses, worms, and more. It can harm your system, steal data, or demand a ransom. This makes it a big worry for everyone online.
Phishing attacks trick people by looking like trusted contacts in emails. They aim to steal info and passwords. There are different types, like spear-phishing and whaling, targeting specific people.
Password attacks are a big deal too. Hackers use methods like brute-force attacks to guess passwords. Strong passwords and extra security steps can help fight this.
Man-in-the-Middle attacks happen when hackers tap into your online chats. They can steal and change data. Staying off public Wi-Fi and using encryption helps avoid these threats.
Other threats include SQL injection attacks, DoS and DDoS attacks, and insider threats. Each one needs its own defense plan. A strong cybersecurity plan is key to stay safe.
Knowing about these threats helps us protect our online stuff. It’s important for both people and companies to stay ahead of these dangers.
