In enterprise Kubernetes environments, security risks often arise from overlapping administrative access. Platform engineers, infrastructure operators and developers may all touch sensitive resources, like secrets. This creates opportunities for privilege misuse or data exposure. By separating admin duties using Confidential Containers, organizations can prevent insider threads, simplify compliance, and align with zero-trust principles.Kubernetes role-based access control (RBAC) enforces access policies by defining roles and permissions for users, groups, and service accounts. It allows you to

The demand for AI talent has surged by 450% in the last five years, and 65% of future generations will work in jobs that don’t yet exist. AI is transforming industries, economies and daily life at an unprecedented pace. By 2030, AI is projected to add $15.7 trillion to the global economy, and the European Union plans to invest €20 billion per year in AI initiatives. Yet, despite this rapid growth, a critical challenge remains: the AI skills gap. A Red Hat EMEA survey showed that AI is a key driver of cloud investments for IT managers, yet AI is the #1 skills gap for respondents.At Red Hat,

Firewalls are essential components in cybersecurity that control incoming and outgoing network traffic based on predetermined security rules. Firewalls can be categorized in several ways based on how they operate and where they are deployed.

Here’s a breakdown of types of firewalls:

🔹 1. Packet-Filtering Firewalls

How it works: Inspects packets (headers) and allows or blocks them based on IP addresses, ports, or protocols.

Layer: Network Layer (Layer 3)

Pros: Fast and simple

Cons: Doesn’t inspect payloads; limited protection against complex threats

🔹 2. Stateful Inspection Firewalls

How it works: Tracks the state of active connections and makes decisions based on the context of the traffic (e.g., TCP handshake).

Layer: Network & Transport Layers (Layer 3 & 4)

Pros: More secure than packet-filtering; tracks connection state

Cons: More resource-intensive than stateless filtering

🔹 3. Application-Level Gateways (Proxy Firewalls)

How it works: Acts as a proxy between users and the resources they access, inspecting the actual data (e.g., HTTP traffic).

Layer: Application Layer (Layer 7)

Pros: Deep inspection of traffic; can log and filter based on content

Cons: Slower performance; more complex to manage

🔹 4. Next-Generation Firewalls (NGFW)

How it works: Combines traditional firewall with advanced features like:

Deep Packet Inspection (DPI)

Intrusion Detection/Prevention (IDS/IPS)

Application awareness

User identity tracking


Layer: Multi-layer (3 to 7)

Pros: Advanced threat detection, modern security capabilities

Cons: Expensive; requires skilled admins

🔹 5. Circuit-Level Gateways

How it works: Monitors TCP handshakes and sessions without inspecting packet contents.

Layer: Session Layer (Layer 5)

Pros: Lightweight and fast

Cons: No payload inspection; can’t prevent content-based attacks

🔹 6. Cloud-Based Firewalls (Firewall-as-a-Service – FWaaS)

How it works: Centralized firewall delivered via the cloud, protects users and devices regardless of their location.

Use case: Remote workers, branch offices, hybrid clouds

Pros: Scalable, easy to deploy, no physical hardware

Cons: Internet dependency; trust in third-party provider

🔹 7. Web Application Firewalls (WAF)

How it works: Specifically filters, monitors, and blocks HTTP/S traffic to and from web applications.

Focus: Protects against OWASP Top 10 (e.g., SQLi, XSS)

Pros: Essential for modern web apps and APIs

Cons: Not a full replacement for a network firewall

🔹 8. Host-Based Firewalls

How it works: Software-based firewall installed on individual servers or endpoints.

Scope: Local to the host

Pros: Fine-grained control; protects even if the network firewall is bypassed

Cons: Must be configured on each host; hard to manage at scale

🔹 9. Virtual Firewalls

How it works: Deployed in virtual environments (e.g., VMware, KVM, OpenStack) to secure VM traffic.

Use case: Cloud and virtualized data centers

Pros: Agile, integrates with SDN and orchestration

Cons: Requires knowledge of virtual infrastructure
