You have spent money on software and hardware, implemented best practices, and believe you are secure, right? You may have overlooked the weakest link: your employee. Many breaches occur as a result of an employee mistakenly clicking on a link or visiting a site that allows a virus to be unknowingly downloaded, giving hackers access to your network. Today, a well-trained workforce is a necessity and may even be your most important cybersecurity tool. In this webinar, security expert David Willson will discuss how many breaches have occurred and are occurring, the tools and techniques hackers use to trick employees into clicking on links or opening attachments, and how to prevent such behavior.

Leadership is evolving beyond traditional leadership skills, and it has never been so important. In an era of constant change, digital disruption, increased employee expectations and rising business complexity, today’s leaders require more than the fundamentals.  In years past, leadership development focused on helping leaders set performance expectations, communicate effectively, provide feedback, coach and motivate their employees. While these skills remain important, they are no longer sufficient to meet the business requirements of the 21st century. Leaders now require skills and competencies to ensure that they also build highly productive teams, accelerate organizational results and transform customer experiences in a fast-paced, highly competitive and global working environment. In this hour-long webinar, leadership consultant Kim Caughlin will reveal and discuss the new high-demand skills and competencies required to lead effectively in the 21st century.

In the last two posts I discussed aspects of services in the context of some landscaping work that I’m having done. This is clearly what many people would call a “non-IT example.” I often use similar examples in my classes. However, I might initially describe an example that seems unrelated to IT, but will conclude with a challenge to students. That challenge is, “identify the IT in this example.” The truth of the matter is that most businesses these days are underpinned by some form of information technology. In fact, technology has become so ingrained into everyday services that often even the service providers themselves don’t realize how technology supports their business.

The ITIL® event management process defines three event types: informational, warning and exception. In this post, I will discuss the different event types and give real-world examples of each.
