VPN stands for Virtual Private Network and is a type of secure connection that creates a barrier between you and the internet, allowing you to access the web safely and privately. VPNs work by encrypting your data and connecting you to an external server, which routes your data through its own server before it reaches its destination. This helps protect your data from prying eyes and malicious activity. VPNs are used to protect sensitive information when browsing online, such as credit card numbers or passwords. Additionally, they allow users to unblock content that may be blocked in their current location. For example, if you are traveling abroad and want to stream video content from home, a VPN can help you bypass geographical restrictions. Finally, VPNs play an important role in cybersecurity by helping keep personal information safe from hackers and other cybercriminals. By avoiding public networks or accessing the internet through a secure connection like a VPN, individuals can reduce their risk of being targeted by malicious attackers.

API Token is an authentication mechanism used to identify and authorize users when accessing a website or application. It enables secure access by providing a unique, encrypted identifier that is used to approve user access. API tokens are used as an additional layer of security, ensuring only authorized users have access to the application. They are easy to use - simply enter the token when prompted during the login process. This reliable form of authentication helps ensure your data remains secure and private.

Faas means Firewall as a Service. You can use the firewall as a hardware appliance (physical computer in your network), as a virtual appliance (still a computer, but it's running in the cloud), or you can pay for a firewall as a service. It means you are not responsible for the firewall itself. Instead, your provider is making sure it's running and secure; you are just specifying what it should be doing. An example is Azure Firewall.

Mandatory Access Control (MAC) is a type of access control system that limits access to resources based on security labels. It is used in many different types of organizations and for many cyber security purposes. MAC works by assigning each user a specific label, or clearance level, that determines what data they can view or modify. Access to sensitive information like financial records or customer data is limited to those with the highest clearance levels, while access to less important information is made available to everybody. By setting up these levels of security, organizations can ensure that only authorized users are granted access to sensitive information, providing them with increased security and protection from malicious attacks.

A Firewall is a tool for securing a computer or network environment. It acts as a barrier between the internal and external networks, preventing malicious traffic from entering the network while allowing legitimate traffic to pass through. Firewalls are used to protect valuable data from unauthorized access, detect and prevent attacks, and ensure that only approved users can access restricted areas. Firewalls use various technologies such as packet filtering, application gateway security, URL filtering, etc., to monitor and control incoming and outgoing network traffic. To use a firewall effectively, it must be properly configured according to the specific needs of the organization.
