What is a firewall?
A firewall is a security device available as computer hardware or software. It can help protect your network by acting as an intermediary between your internal network and outside traffic. It monitors attempts to gain access to your operating system and blocks unwanted incoming traffic and unrecognized sources.
How do firewalls work?
A firewall acts as a barrier or gatekeeper between your computer and another network like the internet. It works like a traffic controller, monitoring and filtering traffic that wants to gain access to your operating system.
What does a firewall protect against?
A firewall protects you from unsolicited and unwanted incoming network traffic. It validates access by assessing this incoming traffic for anything malicious like hackers and malware that could infect your computer.

Encryption is one of the most basic concepts in the world of cybersecurity as it ensures that some information does not fall into the wrong hands. There are two primary types of encryption techniques:
1. Symmetric Encryption:
Encryption is a process to change the form of any message to protect it from reading by anyone. In Symmetric-key encryption the message is encrypted by using a key and the same key is used to decrypt the message which makes it easy to use but less secure. It also requires a safe method to transfer the key from one party to another.
2. Asymmetric Encryption:
Asymmetric key encryption is one of the most common cryptographic methods that involve using a single key and its pendent, where one key is used to encrypt data and the second one is used to decrypt an encrypted text. The second key is kept highly secret, while the first one which is called a public key can be freely distributed among the service’s users.
