Is it Safe to Use Unsecured WiFi in Hotels?

No, it is not safe to use unsecured WiFi in hotels. Using any public WiFi network presents a risk to your private information and security. There are many threats that you become vulnerable to on unsecured hotel WiFi such as a man-the-middle attack or malware. Read on to learn more about the risks of using unsecured WiFi in hotels and how you can stay safe if you can’t avoid using it.

What is CGNAT (Carrier-grade NAT)?

Today we'll be discussing CGNAT, or Carrier-Grade Network Address Translation. This technology was created to address the finite number of public IP addresses that were available under the IPv4 protocol. In the 1980s, it was anticipated that each computer would have its own unique public IP address, but the total number of addresses available, 4 billion, eventually ran out. As a result, IPv6 was developed to address the limited address space of IPv4, but it is not backwards compatible.

Load Balancing Kubernetes Application Traffic for Best Results

In the same way that conventional software relies on application load balancers for dependability, accessibility, and efficiency, a cloud-based setup necessitates a cloud load balancer to distribute workloads across a company's cloud resources. It's crucial to balance the traffic of Kubernetes applications for optimal user experience. A cloud load balancer spreads network traffic across multiple clouds and load balancing traffic for Kubernetes applications, allowing for the distribution of demand evenly across the Kubernetes pods that constitute the service.

Kubernetes network policy best practices

Controlling and filtering traffic when containerizing a workload within Kubernetes Pods is just as crucial as a firewall in a more traditional network setup. The difference is that, in this scenario, those capabilities are provided by the Kubernetes NetworkPolicy API. This article will explore Kubernetes NetworkPolicy by creating an example network policy and examining its core parameters. Then, we’ll look at some common NetworkPolicy use cases and learn how to monitor them using kubectl.

Firewall Log Management and SIEMs

Firewalls are the first line of defense in any network. Firewalls can be software or appliances, and organizations can configure them up to allow or disallow some or all IP traffic, or to verify specific traffic types based on rules that use deep packet inspection. For maximum effectiveness, it’s critical to monitor the operation of your firewalls to spot threats and misconfiguration.
