Networks are the lifeblood of any business. This is why we have developed a few rules for better Internet and Networks.
If you have a Remote Access VPN, it is important to ensure that the VPN is secure. VPNs are a common point of attack in cyber security incidents - if a bad actor can get into your VPN, they're in your network.
If you are going to install a service pack on a machine, moving a virtual server to another drive or doing any critical system level changes, make sure you back up your machine first. For virtualized machine, make sure you back up all related files, including vhd, avhd etc.
w3dt.net supplies a DNS report tool which can help administrator to troubleshoot DNS issues with domains, name servers, SOA, and other information. We need to get all green ticks except for:
Keeping networks and VLANs separated is an essential aspect of a robust security strategy. This is particularly true for less secure networks such as automation and HVAC systems, which are often targeted by cybercriminals looking to gain unauthorized access to the network.
Have you ever faced a scenario where an unauthorized device is discreetly connected to an open port on your network switch, potentially intercepting sensitive data or disrupting critical services? This situation isn’t just theoretical - it can lead to serious security breaches, data theft, and system downtime if you do not restrict the MAC addresses allowed to connect.
The goal is: No one is stressed thinking their backup is not working.
Follow up your team to back up their PCs, then their mobile phones.
Microsoft Update is a service that allows for the periodic patching of system files to address known issues with Microsoft products. Originally called Windows Update, it was specifically focused on Operating System patches for Windows but has been expanded to include all Microsoft products and the name has changed to Microsoft Update, allowing the automated patching of non-OS software such as Internet Explorer and Microsoft Office.
When we configure networks we give all computers in the company a naming theme like:
- Buildings
- Cars
- Countries

- Fruits
- Vegetables, etc
