Why Port Monitoring is Important for Security

Why Port Monitoring is Important for Security

As IT pros already know, when we speak of ports, we mean the 16-bit virtual ports used when interconnecting systems i.e. during communication over protocols such as TCP or UDP and not physical connections on the system such as USB, HDMI etc. See the OSI model and list of port numbers and their assigned function if not an IT pro.

WhatsUp Gold vs. Azure Application Insights

Disclaimer: Azure Monitor’s official documentation is more than 2700 pages of fascinating material. Azure Application Insights is a small part of it. Given the variety of nodes, features, apps and development methods in an Azure infrastructure, app and performance monitoring objectives can be achieved in many ways.

Why Azure is Better Than AWS

Why Azure is Better Than AWS

If you are reading this, you are likely interested in or already utilize cloud solutions. Both Azure and AWS (Amazon Web Services) offer a variety of infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS) offerings. Selection between the two, with AWS the dominant market leader, is typically based on business requirements and online research or direct referrals (some of your contacts recommend a solution based on pricing, uptime or other).

5G is Coming – What Does It Mean For Your Business?

Often perceived as a precursor to Industry 4.0, the rollout of 5G, if the marketing is to be believed, will allow innovations that were previously restricted or unreliable due to lack of bandwidth. Speeds of up to 10Gbps are promised by telecom companies but since we have yet to experience real-life usage scenarios, this is mere speculation.

Are Disruptive Technologies Making Bandwidth Monitoring More Important?

Are Disruptive Technologies Making Bandwidth Monitoring More Important?

As a former cubicle-based drone, I can readily identify with the bandwidth problems faced by users, with slowdowns and interruptions suffered for a variety of reasons, whether it is essential backups best run after-hours, problems with new security patches or updates, failing hardware or streaming video addicts.

How to Easily Monitor Bandwidth Usage Per Device

How to Easily Monitor Bandwidth Usage Per Device

For home users, monitoring bandwidth usage per device may seem like a pointless exercise but their business counterparts typically recognize the value of doing so. Bandwidth is not a limitless resource and total broadband bandwidth (as provided by your internet service provider or ISP) is shared between all the devices connected to the network.

Managing User Permissions in Active Directory is the Logical Choice active directory

Managing User Permissions in Active Directory is the Logical Choice

Users are part of any network and while sometimes troublesome, it’s the responsibility of the IT admin team to ensure that users can access only the resources necessary to perform their roles. The receptionist has no need to access software project data and software developers have no interest in HR resources. Therefore, user permissions are necessary.
