What is FWaaS? Firewall as a Service (FWaaS) is a cloud-based security solution that delivers firewall functionality via the internet, rather than through traditional on-premises hardware. It provides centralized, scalable, and policy-driven protection for users, applications, and data—no matter where they’re located. Key Features of FWaaS: Cloud-Native Firewall Hosted in the cloud, removing the need…

 What is extended ACL (access control list)?                   An Extended Access Control List (ACL) is a type of ACL used in networking, particularly in Cisco devices, to control traffic based on multiple criteria such as source and destination IP addresses, protocols, and port numbers. It provides more granular control compared to Standard ACLs, which can…

What is just in time access? Just-in-Time (JIT) Access is a security practice where users, applications, or devices are granted access to systems, resources, or data only for a limited period of time — and only when it’s absolutely necessary. How it Works Instead of giving permanent access (which increases risk), JIT access allows users…

What is the principle of least privilege (PoLP)? The Principle of Least Privilege (PoLP) is a foundational security concept that dictates that users, systems, and processes should be granted only the minimum access and permissions necessary to perform their designated functions. This principle applies to human users—such as employees, contractors, and administrators—as well as to…

What is zero trust access control? Zero Trust Access Control is a security framework that operates on the principle of “never trust, always verify.” It requires strict identity verification for every user and device attempting to access resources, regardless of their location—whether inside or outside the network perimeter. Key Principles of Zero Trust Access Control:…

What is a MAB account? A MAB (MAC Authentication Bypass) account is a network access method used in environments that require device authentication but where traditional user-based authentication methods (such as 802.1X) are not feasible. MAB allows devices to connect to the network by verifying their MAC (Media Access Control) addresses, which are unique identifiers…

How does Aruba ClearPass work? Aruba ClearPass, while a powerful network access control (NAC) solution, comes with challenges and potential drawbacks that organizations should carefully consider before implementation. Key Concerns with Aruba ClearPass: Complex Implementation: Setting up ClearPass can be overwhelming, especially for organizations without a large IT team. The solution requires significant configuration, including…

What does FortiNAC do? FortiNAC is designed to provide network visibility, device profiling, and policy enforcement to secure network access. However, its implementation and functionality face several technical challenges and limitations that can negatively impact its effectiveness: 1. Architecture and Deployment Challenges Out-of-Band Operation: FortiNAC operates out-of-band, avoiding inline network traffic processing. While this reduces…

How does Forescout NAC work? Forescout Network Access Control (NAC) is designed to provide organizations with visibility and control over devices connecting to their networks. In theory, it promises to enforce security policies, ensure compliance, and mitigate risks associated with unauthorized devices. However, in practice, many organizations report significant challenges with its implementation and performance:…

How can customer identity and access management improve the user experience without compromising security? Customer Identity and Access Management (CIAM) enhances both security and user experience by streamlining how users engage with applications while protecting sensitive data. A robust CIAM solution simplifies access through single sign-on (SSO), which allows users to log in once and…

What is Network Access Control and How Does It Work? Network Access Control (NAC) is a security framework that governs how devices connect to a network, ensuring only authorized and compliant devices can access company resources. The primary goal of NAC is to enhance network security by enforcing policies that verify the identity and status…

What is a network access control list, and how does it function within an enterprise network? A network access control list (ACL) is a fundamental component of network security, operating as a list of rules designed to filter incoming and outgoing traffic across network devices like routers, firewalls, and switches. The primary function of a…
