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.

802.1x is an authentication protocol used for network access control. It allows users to be authenticated before being allowed connection to a local area network (LAN). It helps ensure only authorized users can gain access, protecting the network from malicious activity or data loss. To use 802.1x, devices must support the protocol and have an authentication server in place. The device attempting to connect sends credentials which are verified against those stored on the authentication server before granting access.

SSL (Secure Sockets Layer) is the most widely used security protocol on the Internet. It is a technology that establishes an encrypted link between a server and a client, ensuring that all data passed between them remains private and secure. It works by verifying the identity of each end using digital certificates issued by Certificate Authorities, to ensure secure communication between the two. SSL is mainly used for e-commerce websites to ensure safe online transactions for their customers. It can also be used to secure email servers, webmail services, instant messaging applications and other online communication services. Additionally, SSL helps protect against cyber attacks as it provides encryption and authentication capabilities that help prevent unauthorized access to sensitive information. By providing data encryption and authentication measures, SSL can help protect organizations from malicious attempts to compromise networks or harvest data.

Cross-site scripting (XSS) is a type of cyber attack where malicious code is injected into websites to steal user data. It can be used to gain access to administrative accounts, redirect users to other pages or inject malicious content onto the website. XSS is most easily deployed by sending malicious code via links or web forms and can be prevented with proper validation and sanitization techniques. XSS attacks are extremely dangerous as they can allow attackers to control your website and access confidential information.

mTLS (mutual TLS) is a cyber security protocol that provides secure communication between two or more entities. It works by authenticating each party involved in the communication through encryption and certificates. mTLS establishes trust between parties, ensuring that only those with valid certificates can access the network, data, or application. This makes it difficult for malicious actors to infiltrate or tamper with data as they need a valid certificate to gain access. mTLS is used in many industries, including finance, healthcare and e-commerce, to protect sensitive information from unauthorized access and ensure the authenticity of transactions. mTLS provides an extra layer of protection for digital assets and services, making it essential for organizations looking to adopt robust cybersecurity measures.
