Follow @ASM_Educational Using DHCP Server with Inter-Vlan Routing (Router on stick) On Last Video we talked about the router on stick that is we made sure that client from Network 10.10.10.0 can communicate with Network 20.20.20.0
Follow @ASM_Educational Setting up VLAN’s On a new switch, all the ports are in VLAN 1 by default. We just plug in the Ethernet cables and the devices can communicate. Furthermore, all the ports are in the up/up (administratively up) mode.
Alternatively referred to as a bus slot or expansion port, an expansion slot is connection or port located inside a computer on the motherboard or riser board that allows a computer hardware expansion card to be connected.
Power Supplies Okay, now that we’ve tested our AC outlet and put some protective power devices into play, let’s go ahead and talk power supplies.
You may not typically handle the insides of your computers, but if your business requires knowledge of Central Processing Units (CPU), then you’ll also need to learn about CPU sockets

Tunneling is a method of transferring data from one network to another by encapsulating the packets in an additional header. The additional header provides routing information so that the encapsulating payload traverse the intermediate networks.
IPSec IPSec is an architecture or framework for security services for IP networks. It works at the Network Layer of the OSI Model. It is actually a standard for secure data transmission. It provides mechanisms for authentication and encryption. Defined by RFC 4301 and carries a set of functions, it is mandatory in IPv6. IPSec… Read more »

The Types of Wireless Attacks Part 2 CompTIA Security+ Objective 1.2 WPS Attacks Wi-Fi Protected Setup (WPS) allows users to configure a wireless network without typing in the passphrase. Instead, users can configure devices by pressing buttons or by entering a short personal identification number (PIN). For example, a user can configure a new wireless… Read more »
The Types of Wireless Attacks Part 1 CompTIA Security+ Objective 1.2 Replay Attacks A replay attack occurs when an attacker copies a stream of messages between two parties and replays the stream to one or more of the parties. Unless mitigated, the computers subject to the attack process the stream as legitimate messages, resulting in a range… Read more »
CompTIA and Immersive Labs are challenging cybersecurity professionals in the United States and United Kingdom to test their penetration testing skills this month. The two organizations launched the pen test challenge on the opening day of RSA® Conference 2019. “Penetration testing, if done right, is a proven and valuable activity that all organizations should engage… Read more »
The nature of cyberattacks is constantly in flux, always evolving to keep pace with the times. Hacking of websites, theft of credit card information and other personal information has become an almost daily occurrence, along with illegal remittances via Internet banking. Recent years have witnessed the accelerating dissemination of new technologies such as IoT… Read more »
Richard Clarke, a former counter-terrorism expert for the United Government, once said, “If you spend more on coffee than on IT security, you will be hacked. What’s more, you deserve to be hacked”. While the latter is a tad harsh (we wouldn’t wish a cyber attack on anyone!), the former is certainly true. If you… Read more »
