Electricians use a special tool called a fish tape (a stiff wire with a hooked end wound onto a spool) to thread cable through walls. If you have a fish tape, feed the tape into the cavity and out through the box hole, then secure the end of the NM cable onto the hook of the ta...
Doing this will make you significantly more secure than the majority of people, who don't do this. Understand your adversaries There's no such thing as a system being secure, only being secure against a particular adversary. This is why it's important to understand who your adversaries are,...
A soft firewall is generally one that is installed on the system and provides an easy-to-use interface. A hard firewall is an appliance installed on the consumer’s home network, and moderates the traffic coming in and out of the network. "User’s need firewalls to ensure that their sys...
You've learned about the purpose of the Azure ExpressRoute service, and the services for which you can use it. Now you're ready to start learning about how the service works. Let's examine how it interacts with Azure and on-premises networks to help create a secure and reliabl...
From the answers to these questions, you should hopefully be able to determine how secure the Ethernet setup is -- and hopefully write recommendations to improve security based on what you find. Like I said earlier, though, you should definitely check with the client before...
or just simply changing over an electrical wall switch or outlet, I'm here to help. I will show youhow to wire a 2-Way Switchorhow to wire a 3-Way Switchor even how to wire an Outlet, but also teach you a little bit of theory on how the circuit is controlled. So if you are...
Thread the wire through the next eyes in a line, according to your pattern. At an opposing corner, loop the wire through the eye, pull it taut, and secure it with a ferrule. Based on your pattern, you can minimize the number of places you need to secure the wire. I ended up using...
Use secure protocols and software. Non-encryption protocols transmit data packets in plaintext. Attackers can use tools such as Wireshark to easily capture network traffic and view sensitive information such as passwords transmitted in plaintext. Therefore, use encryption protocols instead of non-encryp...
Another reason to use Wireshark to sniff networks is for security troubleshooting of network devices or applications. For example, you can use Wireshark to troubleshoot firewall rules. If systems running Wireshark are connected to either side of a firewall or router, you can see which packets...
Devices and their apps have regular updates that developers create to keep them secure and working as they should. Neglecting updates could leave vulnerabilities for hackers to exploit, which is bad news for your data. Regularly check for device and software updates. Better yet, switch on automati...
