The short answer (and a common one in our industry): it depends. When comparing Cisco IOS with Juniper Junos, the decision to choose one over the other is difficult and often boils down to cost. Of course, there are other factors to consider.

I recently responded to a message on LinkedIn from a regular reader of this blog. He asked several questions which I will answer over the course of several posts. As part of his first question, he described a strategy report that his group is producing. The audience for this strategy report considers ITIL important to the future of their business, and so he must describe which ITIL processes his data center operations group works most closely with.

Systems Administrators, or SysAdmins for short, are most often frontline IT staff who are problem-solvers, (metaphorical) fire extinguish-ers, and, simply, doers.

This webinar covers the evolution from physical servers to VMs to containers and the driving factors behind this change. We explain why containers are useful in an enterprise environment and why they are so popular with developers and administrators. In addition, we list the available container solutions on AWS (Elastic Container Services – ECS, Elastic Kubernetes Services – EKS, and Fargate), GCP (Google Kubernetes Engine – GKE), and Azure (Azure Container Instances – ACI and Azure Kubernetes Service – AKS).   View the slide deck>

Examine the evolution from physical servers to VMs to containers and the driving factors behind this change. Also review the available container management solutions on AWS, Google Cloud Platform and Microsoft Azure. 

Cybersecurity is one of the most important fields of work in our world today. It’s an ever-changing discipline that requires ongoing education and adaptability, even for cybersecurity experts.

As organizations struggle to balance budgets and prioritize training, skills gaps are growing—75% of North American decision-makers report existing skills shortages. And the impacts are potentially disastrous. With so much on the line, initial and ongoing training are instrumental to project and organizational success.

Instructor-led training (ILT) allows the student to attend a live class taught by a subject matter expert they can interact with. When you need to gain skills that provide a high benefit or pose a critical risk to your business, instructor-led training guarantees your highest chance of success.  

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?

Michael Scarborough and Ryan Ballmer, co-authors of Global Knowledge ITIL courseware, discuss why ITIL is important to businesses.

Watch this recorded webinar to understand the basics of the Risk Management Framework (prescribed by NIST Standards) and how to begin to apply it.  

The use of public networks is risky. Whether wireless or wired, any public access Internet connection is putting you and your data at risk. It may be convenient to use a hotel, restaurant, or coffee shop Internet link, but the likelihood of attack or compromise is greater than accessing a private network.

For organizations with the willingness to get in shape and regain their corporate vitality, combining and aligning best practice frameworks is a sure way to achieve that goal. Admittedly, it takes work. Combining ITIL® 4 and project management should be high on your list.

Hackers are everywhere, and they have a sophisticated array of tools for cracking your passwords. The primary purpose of this white paper is to help you understand that easy-to-remember passwords are no longer considered a secure form of authentication

Watch this recorded webinar as CompTIA’s chief technology evangelist and Global Knowledge’s federal sales director discuss how pentesting has morphed.

The benefit of Private Group Training (PGT), particularly when it comes to high-priority or high-risk skills, is it gathers a group of like colleagues together in front of a subject matter expert. PGT, which can also be referred to as onsite training, coordinates the group, eliminating the disparity between co-worker skill sets.

Does your company have a risk management program? In this hour-long webinar, cybersecurity expert and Global Knowledge instructor David Willson will explain why you should. In light of recent breaches at Target, Nieman Marcus, Michaels, Yahoo, and a growing list of others, we're learning that FBI Director Mueller was right when he said getting breached is not a matter of if, but when. While having a risk management program may not prevent a breach, it can certainly lower the risk of one, ensure compliance, and reduce or even eliminate your liability if a breach does occur, enabling you to recover quickly and to protect your reputation. Beyond explaining the importance of a risk management program, David will tell you how to implement one, including conducting a basic risk assessment, policies you'll need, and training your workforce.

Are you at a crossroads professionally or looking to start training for a new job? If so, you might want to consider pursuing network administration as a career. Network administrators are responsible for maintaining computer hardware and software systems that make up a computer network, including maintaining and monitoring active data networks, converged infrastructure networks, and related network equipment.

Spanning Tree Protocol (STP) is dead, or at least it should be. It’s too slow to converge when there’s a change, and it causes issues with performance because there is only one forwarding path. It was developed in 1985 by Radia Perlman at Digital Equipment Corporation to allow for redundant paths within a Layer 2 topology, which was great in 1985. In fact, it was huge! So much so, that it was later standardized by the IEEE as 802.1D, and we’ve been living with it ever since.

On September 26, 2016, Microsoft announced the general availability of Windows Server 2016. We already have a taste of what the user interface looks like from Windows 10. In actuality, there are a few other features that Windows 10 picked up first, such as PowerShell 5.0 and the latest version of Hyper-V, that are also part of Windows Server 2016. Many other heavy-hitting server-only features will be here soon.

If you are considering career options or have been in the workforce a few years and are seeking a career change, you might want to consider training to become a computer support specialist.

Chief Technical Architect Craig Brown discusses the Windows 7 certification and skills tracks available to Global Knowledge students.

In this video, Practice Leader Craig Brown discusses our exclusive Server 2008 course - Configuring, Managing, and Maintaining Server 2008 R2 (M6419). Specifically, the enhancements we've made to this course through Server 2008 R2 supplemental learning materials and custom hands-on labs that enable the student to utilize critical Server 2008 R2 functions after completing the course.

New in Windows Server 2012 is the Unified Remote Access (URA) role. In Windows Server 2008 R2, DirectAccess and Routing and Remote Access Service (RRAS) were two separate roles. In fact, they could not be co-located on the same server. In Windows Server 2012, DirectAccess and RRAS can be co-located, allowing for what is now legacy remote access VPN client connectivity (L2TP/IPsec, PPTP, and SSTP). This means that the Unified Remote Access provides DirectAccess, Remote Access VPN, and site-to-site VPN and can now serve as your complete remote access solution.

There are several Wireless LAN Standards, including b, g, and n, which exist in the 2.4 GHz band. These standards need around 20 MHz of radio frequency in order to transmit their signals. In this video, Ben Miller discusses how to pick access points and channels for optimal performance.

For women in IT, advancing your career can be a challenge in itself. In the Global Knowledge 2019 IT Skills and Salary Report, only eight percent of senior- and executive-level IT professionals are women. We have pulled data from our research that sheds light on the job roles, skills, challenges, certifications and experience of women in tech who have progressed to the highest levels of an organization.

The novel coronavirus has changed many aspects of life for millions of people globally, including where they work. With the increase in remote work, it is important for both individuals and companies to be aware of the added cybersecurity risks. Join us as Paula shares real world examples and tips on how we all can be better prepared.

If you’re worn out by daily road rage—how many middle fingers can you see in one day—or irked at the prospect of being taxed to death, maybe it’s time for a change. Future job opportunity, salary, cost of living and quality of life are a balancing act. We can’t tell you what to do, but we can let you know where IT professionals are making the highest average salaries in the U.S.

Shortly after being awarded an ITIL® Foundation certification, a recipient’s natural inclination is to ask: “Now what? How do I take the best practices I’ve learned and apply them to my organization?”

Most of us have heard of "oversharing" in the social sense (i.e. giving out too many details of your personal life), but how about "under sharing" in the Windows Server realm? What does that even mean? Well, I sort of just made that up, but it does actually make some sense when you think about it in terms of creating a Windows Share that doesn’t provide enough permissions.

For several years, most news articles about a computer, network, or Internet-based compromise have mentioned the phrase "zero day exploit" or "zero day attack," but rarely do these articles define what this is. A zero day exploit is any attack that was previously unknown to the target or security experts in general. Many believe that the term refers to attacks that were just released into the wild or developed by hackers in the current calendar day. This is generally not the case. The "zero day" component of the term refers to the lack of prior knowledge about the attack, highlighting the idea that the victim has zero day's notice of an attack. The main feature of a zero day attack is that since it is an unknown attack, there are no specific defenses or filters for it. Thus, a wide number of targets are vulnerable to the exploit.
