October is Cybersecurity Awareness Month and being aware of all your devices is as important as ever before. Most people are online every day, which opens themselves up to a threat of being hacked. Whether it be a mobile device, laptop, or personal computer, everyone needs to have cyber awareness.


Steven Weldon, director of the Cyber Institute at Augusta University’s School of Computer and Cyber Sciences said many straightforward things that can be done to protect devices, such as having lock screens, making sure operating systems are up to date and simply recognizing how, when and where devices are being used.


“Smart phones today are probably the most capable computing device that we have and we have it on us all the time,” said Weldon.



“The data that can be extracted from these devices can be put together to build a pattern of life on us: where we go, what we do and when we do it. All of this data is potentially at risk if we’re not being careful about who gets access to our smart phones. That’s a great reason to lock the screen and require at least a password or pin to unlock the phone.”


Gokila Dorai, PhD, assistant professor in the School of Computer and Cyber Sciences, suggests using biometrics to enhance security.


“I would strongly recommend for women, young adults even teenagers, if it’s possible for you to have biometrics as a way to unlock your device, then go for that. These unique ways of unlocking a device would add a layer of protection,” said Dorai.



Dorai is one of the growing experts in the field of mobile forensics and her research projects are federally funded. In addition, several SCCS faculty are mentoring undergraduate and graduate students working on cutting edge research related to mobile device security and digital forensics.


She also suggested adding a two-factor authentication or multi-factor authentication to add an extra layer of security.


When out in the public, it’s easy to connect a mobile device to an unprotected Wi-Fi network. Doing so could open up sites you visit to a hacker. Weldon suggests people should be careful of what apps are used when on public Wi-Fi, since they may expose a lot of personally identifiable information. His suggestion is to use a virtual private network to help protect data that’s being transmitted and received.


“We should recognize the data on our smart phones and protect them accordingly,” added Weldon. “Recognizing the value and sensitivity of the data on our smart phones can guide us in how we protect these devices. We may not think as much about the security and privacy of our smart phones as we do about our laptops and desktops. When we think about everything we use our smartphones for, how ubiquitous they are in our lives, we come to realize just how central they are to today’s lifestyle in the digital age.”


It’s tough to identify when a mobile device has been hijacked, so both Weldon and Dorai suggest paying close attention to any unusual behavior, even small things such as a battery draining faster than usual. Both are indicators you may need to take corrective actions.



Dorai added the government can do more to protect a person’s privacy.


“With the introduction of more and more Internet of Things devices in the market, with several different manufacturers, there’s a lot of user data that’s actually getting exchanged. These days, the most valuable thing in the world is data. So stricter measures are required,” she said.


She indicated it needs to be a collaborative effort between industry, academia, government, and practitioners to come together and work on ideas to strengthen security.



“Yes we want security. We are willing to put up with a little bit of friction for additional security. We want it easy and we generally want it free,” said Weldon. “We don’t read licensing agreements, but we would generally be willing to take certain actions, make certain tradeoffs, to be more secure.”


One other major concern are apps in general. While Google Play Store and Apple routinely remove some apps that may be out of date or have security vulnerabilities, they may still be running on a user’s device.


“Mobile applications may also hide from you in plain sight in the sense the app icons may not be showing up on the screen, but still they are running in the background,” added Dorai.




In essence, the device user is the first line of defense. Taking all the necessary steps to prevent a third party from getting your information is of the utmost importance in the digital age.


“I believe a big part of it this discussion is about user awareness. We want that free app but that app is asking for a lot of permissions. There’s an old saying in cybersecurity: if you are not paying for the product, you are the product. There’s also another saying: if it’s smart, it’s vulnerable,” said Weldon.

Can you benefit in transferring high-interest credit card debt?

Photo credit: paulaveryevans According to Lendingtree, Americans have over $1 trillion in credit card debt. The average American has around $6,500 in credit card debt. When you factor in the high interest that credit cards charge, it can be a daunting task to get the balance to zero. Many cards offer 0% APR on balance transfers for certain length of times. But is it worth it if you don’t plan on paying off the entire balance during the promotional period? Wendy Habegger, PhD, senior lecturer in the James M. Hull College of Business, said you need to be careful when taking advantage of such offers. “The benefit one would get in this situation is short-lived,” said Habegger. “While one might enjoy no interest for the promo period, when that period is over, the interest rate they are charged could be more than the credit card from which they transferred. My recommendation is that if one does a balance transfer, then only do so if you are able to pay off the balance before the period ends.” Some may think of doing a second balance transfer but Habegger said that it is not a good idea and could have a negative impact on a person’s credit score. It also gives the appearance the customer is at increased risk of default, which could trigger an even higher interest rate and higher fees. Not only may one incur higher rates, it could certainly impact their credit score, which can have a long-lasting financial impact. Even a large purchase on a 0% APR card will affect someone’s credit score. “A large purchase indirectly impacts one’s credit score based on credit utilization,” she added. “If one uses more than 30% credit utilization, it could impact credit scores.” Personal debt and credit are trending and important topics in America today - and if you're looking to know more, we can help.

Changes in college football continue to be driven by dollars (and sense?)

The landscape of college sports, and particularly that of college football, has changed significantly in recent years. First, we have seen an almost constant realignment of collegiate athletic conferences, resulting in a few major mega-conferences, such as the SEC and ACC, Big  Ten and Big 12, and the disintegration of a former major conference, the Pac 12. Most of the other changes related to the athletes, such as the ease with which student-athletes could transfer from one school to another and the ability for them to be paid for their name, image and likeness. All of these issues were potentially pointing to new business models in college sports, but within the last week, that landscape was shaken even further. Last week, the NCAA and its five major conferences settled multiple lawsuits to pay past and present student-athletes a total of $2.8 billion. The settlement also laid the foundation for the payments of college athletes starting in fall 2025. “The major unresolved questions are who will get paid and how much,” said Rick Franza, PhD, professor in the Hull College of Business at Augusta University. “If we ‘follow the money,’ we see that football and basketball (particularly men’s basketball) generate almost all of the revenues, and most of the revenues comes from major conferences. Therefore, most of the player payments are going to go to football and basketball, and given the size of the relative rosters, football teams will be much more costly.” Franza added that the settlement will further exasperate the revenue and cost differences between major conferences and their smaller conferences as well as between football and the so-called Olympic sports which generate little, if any revenue. It was always clear that from both a revenue and cost perspective, college football is very different from other sports. Revenues are much higher for the major conferences in football, and there is not the same extent of revenue sharing as there is in basketball due to the NCAA Tournament. On the cost side, with the new realignment of the mega conferences and expanded geographic footprints, there is a significant increase in travel costs for the Olympic sports. “While those expanded conferences were mainly driven by football revenues, they are also making all other sports more costly. Therefore, the time has come to separate football from other sports,” said Franza. One solution was first proposed by Chip Kelly, former Oregon and UCLA head football coach and now Ohio State offensive coordinator. He proposed a 64-school football conference in which the members would share all revenues, including television, which would more easily cover the NIL, and player pay costs. In recent months, similar proposals have been made for a college football “Super League,” which would include up to 80 schools. “This makes too much sense not to happen,” Franza said. “It allows the bigger football schools to share the plentiful available revenues while being able to pay the players what they will demand. At the same time, the other college sports would be able to revert to their traditional, geographical conferences and reduce travel costs driven up by the realigned mega- conferences.” He added that two conferences, the SEC and Big Ten, the most successful under the current alignment, could delay the implementation. Franza also predicts that an agreement taking the first steps toward such a structure will be reached sometime in 2024. “While it makes a lot of sense to go in this direction prior to the player settlement, it makes even more dollars and ‘sense’ now given the settlement,” said Franza. “While  the SEC and BigTen currently make more money than any other conference, I think they will see the light for what is best for the future of college football.” Covering the business of sports and looking to know more?
