Internet Access Security

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.

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.

Allowlist is a tool used to protect digital assets and networks. It blocks malicious activity by creating a list of known safe IP addresses, domains and URLs that are authorized to access the network. This helps prevent unauthorized access, phishing attacks and malicious software downloads. By allowing only trusted sources into the system, organizations can safely manage their cyber security risks. Allowlist/Whitelist is easy to use - it just requires setting up an allowlist policy within the system's firewall.

Content spoofing is a form of cyber attack in which attackers replace legitimate content on a website with malicious content. It is used to distribute malware and steal confidential information from unsuspecting users. Content spoofing can be done by creating malicious websites, inserting malicious code into existing websites or redirecting traffic. To protect yourself from content spoofing, always look for signs of suspicious activity such as unfamiliar URLs, strange pop-ups or sudden changes in the layout of a website.

Network segmentation is a cyber security technique used to divide a network into smaller, isolated parts. It helps decrease the risk of malware or malicious attacks spreading across the entire network, as well as keep sensitive data and applications separate from other less secure components. Segmentation works by creating virtual walls between different network segments, making it difficult for unauthorized users to gain access to restricted areas. This technique is often used in conjunction with firewalls and other security protocols to further reinforce the safety of the network. Network segmentation is extremely important for enterprise-level organizations that have complex networks and need additional safeguards in place. With this technology, they can ensure that their networks remain secure while still allowing authorized personnel access to needed resources.
