Networks are under attack as hackers try to access systems to compromise or steal sensitive data and information. Understand the threats posed by malware, ransomware and social engineering.

To understand the difference between Ethernet II and 802.3, you first must know how Ethernet works. While Ethernet cables transmit data, their role is relatively simple compared to that of the Ethernet card — also referred to as an adapter. It’s within the function of this card that you find the differences between Ethernet II and 802.3.

The bad guys just keep getting better! No matter how much patching and tweaking we do, the bad guys' constantly changing tactics and techniques continue harming our networks, stealing and damaging data, and just generally screw things up. What motivates someone to do such terrible things in the first place? How have these hackers changed and improved? What kinds of attacks are popular now and why? In this hour-long webinar, security expert, former hacker and Global Knowledge instructor Phillip D. Shade will provide insight into understanding the latest hacking techniques, what the current threat landscape looks like, and suggested countermeasures to mitigate threats. He will include specific examples of the current threat landscape, including data mining, social engineering cyber threat terminology, man-in-the- middle attacks and Denial of Service (DoS) attacks.

According to Cisco marketing, Dynamic Multipoint VPN (DMVPN) “will lower capital and operation expenses, simplifies branch communications, reduces deployment complexity, and improves business resiliency.” Okay. But what is it, really, and why should we care?

“Twisted Pair” is another way to identify a network cabling solution that’s also called Unshielded Twisted Pair (UTP) and was invented by Alexander Graham Bell in 1881. Indoor business telephone applications use them in 25-pair bundles. In homes, they were down to four wires, but in networking we use them in 8-wire cables. By twisting the pairs at different rates (twists per foot), cable manufacturers can reduce the electromagnetic pulses coming from the cable while improving the cable’s ability to reject common electronic noise from the environment.

One of the main weapons of organized crime on the Internet is the use of junk email, also called spam. Hackers use spam for a number of purposes such as selling counterfeit products (medicines, particularly) to steal your personal or financial information, or to infect your computer with spyware and malware. This malicious software can then hijack your computer and your Internet connection to help propagate itself.

The Open Group Architectural Framework (TOGAF) provides a structure for describing all transformational work within an enterprise. While TOGAF focuses on the role of an enterprise's architects, it also very much addresses the space in which business analysts (BAs) play. This can lead to role confusion, blurred deliverables, and duplicate work. In this one-hour webinar, business analysis expert and Global Knowledge instructor Adam McClellan will focus on those parts of TOGAF in which the business analyst is typically the most active, and he will outline how the analyst's work contributes to the broader architecture. He will also provide perspective for architects who work with BAs and for BAs interested in the architecture disciplines.

Kirsten Lora, Global Knowledge Senior Product Director, explains the difference between our Business Analysis Essentials course and Business Process Analysis course.

This year, CISSP-certified IT professionals have the third highest global salary ($116,573) and the 10th highest in North America ($123,815). This is nothing new—CISSP has ranked in the top 10 in the U.S. each year since 2015, even coming in first in 2018. CISSP is a top-paying certification year after year. But how has it remained so relevant and valuable?
