As a cybersecurity professional, how numb have you become to vendors who try to scare you with frightening statistics in an effort to sell you a new product? It is understandable that a vendor has to present as much information in a limited amount of attention-grabbing time, so their doomsday technique makes some sense. Perhaps the vendors’ approach...

OVAL is the Open Vulnerability Assessment Language, which uses XML based documents to define vulnerabilities based on characteristics of a host system. It can also be used to gather information about the host. When an OVAL file is evaluated, it generates a report file with the results of the vulnerability evaluation or a system characteristics file...

As I mentioned previously, this year, I’m going back to school. Not to take classes but to teach a course at my alma mater, Fanshawe College. I did this about a decade ago and thought it was interesting, so I was excited to give it another go. Additionally, after a friend mentioned that their kid wanted to learn Python, I developed an Intro to...

2020 was dominated by news of the pandemic and anchored by reality that we all found ourselves in – entire families logging in remotely, trying to keep school and work feeling “normal.” While we tested the limits of what a home office could sustain, the privacy and security of a fully remote world was put front and center. In this piece, we take a...

Unfamiliar territory As a security analyst, engineer, or CISO, there are so many aspects of the field that require immediate attention that one cannot possibly know everything.

As the retail world’s center of gravity shifts to the cloud, payment card fraud has followed suit. According to Verizon’s retail vulnerabilities study, attacks against e-commerce applications are by far the leading cause of retail data breaches. This trend mirrors similar outcomes in other industries, like food service. A complimentary Verizon study...

Last week, the United States Cybersecurity & Infrastructure Security Agency (CISA) advised on initial steps to take in response to the SolarWinds software that was compromised by advanced persistent threat actors. While federal agencies were under a deadline to complete certain actions, this issue will require continued clean-up and longer-term...

We’ve previously discussed best practices for securing Microsoft Azure and Amazon Web Services but, this time, we are going to turn our attention to Google Cloud Platform. Google Cloud Platform (GCP) is growing at an impressive 83 percent year over year but generally receives less focus than AWS and Azure. We can use some of our best practice cloud...

It’s been a little while since we last reviewed a book, but a lot of my team has been spending time with Ghidra this year. Craig Young taught a course on the subject, and I’ve used it with my students at Fanshawe College in their Malware Analysis course. Given our fascination with Ghidra, reviewing The Ghidra Book: The Definitive Guide by Chris...

Life for university students has changed massively during the coronavirus pandemic, as it has for all of us. While some in-person lectures and seminars are still taking place, there has been a big shift to remote learning. This has, perhaps understandably, led to concerns about how well students are engaging with this way of studying. Many...

Digital threats confronting Critical National Infrastructure (CNI) are on the rise. That’s because attackers are increasingly going after the Operational Technology (OT) and Industrial Control Systems (ICS) that shareholders use to protect these assets.
