IT Fundamentals

HTTPS

HTTPS stands for Hypertext Transfer Protocol Secure. It is the secure version of HTTP, which is the protocol used for transmitting data over the internet. HTTPS uses encryption to protect the data being transmitted between a user's browser and a website, ensuring that it cannot be intercepted or tampered with by unauthorized parties. It is commonly used for secure online transactions, such as online banking, e-commerce, and sensitive data transfers.

Security +

The Security+ certification is a widely recognized credential in the field of information security. It validates the knowledge and skills required to secure computer networks and protect against various threats. The certification covers topics such as network security, cryptography, access control, and risk management. It is often sought after by IT professionals looking to enhance their career in cybersecurity.

DNS

DNS stands for Domain Name System. It is a decentralized system that translates domain names (such as www.example.com) into IP addresses (such as 192.0.2.1) that computers can understand. DNS plays a crucial role in the functioning of the internet by enabling users to access websites using human-readable domain names instead of remembering complex IP addresses. It works by using a hierarchical structure of servers that store and distribute domain name information. When a user enters a domain name in their web browser, the DNS system resolves the domain name to the corresponding IP address, allowing the user to connect to the desired website.

Malware

Malware, short for malicious software, refers to any software designed to harm or exploit computer systems, networks, or devices. It includes various types of harmful programs such as viruses, worms, Trojans, ransomware, spyware, and adware. Malware can be spread through email attachments, infected websites, or compromised software. Its effects can range from disrupting computer operations to stealing sensitive information or even taking control of a system. To protect against malware, it is important to use antivirus software, keep software up to date, exercise caution when downloading files, and regularly back up data.
