Organizations and individuals are threatened with ever-growing cyber threats and must be prepared to address them. The more we are connected to networks, the more suspectable we are to attacks, therefore enterprises must stay current applying various cybersecurity measures and maintaining awareness of cybersecurity trends.

Here are 18 certification options, in no particular order, that are worth your effort based on site searches, feedback from subject matter experts and data in the Global Knowledge 2019 IT Skills and Salary Report.

With Multiprotocol Label Switching (MPLS) as popular as it is in the provider space and private MPLS clouds for larger enterprise, we needed some tools to help troubleshoot and maintain these networks. With the providers in mind, the normal ping or traceroute may not be enough.

The key difference between hubs, switches and bridges is that hubs operate at Layer 1 of the OSI model, while bridges and switches work with MAC addresses at Layer 2 of the OSI model.

Early one morning, an engineer end user discovered that the Engineer servers were unreachable, and he didn’t know if he could reach the Internet. The administrator investigated the user’s PC with the IPCONFIG /ALL command and verified that the PC was a DHCP client, but it had received an address from the Accounting DHCP server, not the Engineering DHCP server.

When you connect your server or storage, it will send a Fabric login (FLOGI) request. This FLOGI request serves two purposes: Fibre Channel ID is the WWPN connection to this port from the FLOGI server Exchange buffer credits with the switch To better understand the first function, it is exactly the same if I rewrite it as, “request an IP address for a MAC address from the DHCP server”.

The coronavirus pandemic changed how people around the world work and receive skills training. Virtual meeting services saw incredible growth, they also faced new security challenges. As a key Global Knowledge partner, we worked closely with Gary and the Zoom team as they rapidly upgraded their platform to ensure the maximum possible level of safety for all users. However, technology is only as powerful, or safe as the people who use it. So, in this webinar Gary will provide expert (and entertaining!) advice on how to use virtual meetings safely when there is not a Global Knowledge instructor on-hand to help. Joining Gary is Kevin, our CXO: another big personality with a wealth of IT experience and a passion for ensuring our customers receive the best possible experience, every time they connect with Global Knowledge.

The world of Incident Response is evolving. No longer do we focus on indicators of compromise; we now focus on attacker behavior. MITRE has turned attacker behaviors into a usable framework shared both on their website and on GitHub. MITRE provides the MITRE ATT&CK Navigator on GitHub which includes a complete mapping of all techniques and sub-techniques to help you understand the attacker’s behavior. The Navigator can be leveraged to optimize Incident Response, evolving your team from responsive to predictive response.

The Information Technology (IT) profession is a pretty exciting place to be, right now. We’re seeing an unprecedented influx of new technologies and approaches, including AI, robotics, automation, and next-level networking. More importantly, today’s IT workers have become the guardians of identity and curators of information. Given the increased movement to remote working the IT community must be conscious their teams skillset in the midst of increasing and complex cybersecurity threats designed to hit organizations where it hurts...their people. If you’re curious about what it’s like to be part of the IT profession in quickly changing virtual world, then watch CompTIA’s Chief Technology Evangelist, Dr. James Stanger, to learn more. James discusses the pillars of IT that help create our (post)-modern world, and dispel a few myths about the cybersecurity profession. If you’re interested in learning more about the different cybersecurity pathways available to you, and how you can become a unique contributor to the cybersecurity profession, then we welcome you.
