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.

Software-defined Networking (SDN) is a revolutionary way for networks to be managed and operated. It separates the network control plane from the data forwarding plane, allowing for more flexibility and control. This helps enable automated networking processes, better security measures, and improved performance. SDN is used by organizations that require high levels of agility in their networks, such as those involving large enterprises or cloud computing applications. SDN also benefits cyber security by providing visibility into network traffic and giving administrators more control over how data is routed through the network. This means organizations can better protect themselves from malicious attacks and respond quickly to threats.

An encryption algorithm is a tool used to scramble and protect sensitive information. It works by turning readable data into unreadable code, making it impossible for anyone without the right key to access it. Encryption algorithms are used on websites and databases to keep data secure and safe from cyber threats, ensuring that only authorized users can access the information. To use an encryption algorithm, you must create a key and encrypt your data with it before sending it over the internet.

An identity provider (IdP or IDP) stores and manages users’ digital identities. Think of an IdP as being like a guest list, but for digital and cloud-hosted applications instead of an event. An IdP may check user identities via username-password combinations and other factors, or it may simply provide a list of user identities that another service provider (like an SSO) checks.

Layer 3 hardware is a type of network hardware that is used to read and forward data across a network. It works by reading the IP addresses contained within each packet of data and forwarding them to their destination. Layer 3 hardware is most commonly used in corporate networks, but can also be integrated into home networks for increased security. Layer 3 hardware helps protect against cyberattacks by authenticating users before allowing access to the network, and by detecting malicious traffic before it reaches its intended destination. It also offers additional features like Quality of Service (QoS) for prioritizing important traffic, as well as features like Network Address Translation (NAT) for hiding private IP addresses from public view. By providing these extra layers of protection, Layer 3 hardware helps ensure that data remains secure while it is transferred across the network.
