Looking back at recent data breaches, it’s interesting to note that the largest breaches didn’t involve stolen credit card or social security numbers. Instead a myriad of personal information is being stolen in massive quantities. Why this shift? It’s just more valuable!

Cybercriminals are driven by opportunity and go where the money is. As soon as the good guys figure out how to stop them, they’ve already figured out their next move. So, it’s no wonder that the cyber threat environment is constantly changing, and exploits continue to evolve and shift.

Data classification is as fundamental a part of securing your organization's information as knowing what data you have and who can access it. It's the process of identifying and assigning pre-determined levels of sensitivity to different types of information. If your organization doesn’t properly classify your data, then you cannot properly protect your data.

Email completely changed the way we communicate and the way we do business. While it makes us more efficient, it comes with a cost. And that is the risk of a data breach. There are a myriad of studies that reach the same conclusion year after year. The majority of cyberattacks begin when someone clicks on a link in a phishing email.

Many successful cyberattacks start with someone clicking a link in an email. According to Verizon’s latest Data Breach Investigations Report, phishing and pretexting represented 93% of all social breaches they studied. And email was the most common attack vector (96%). But it’s impossible to imagine doing your job without email, so what can you do to mitigate some of the risk?   

Documenting step-by-step processes that are easy to follow, repeatable, and transferable, is a great way to create institutional knowledge. It makes your organization more cyber mature, and therefore, more resilient. Checklists are one of the methodologies that you can use to make that happen.

It’s not unusual to encounter an organization that is using practical knowledge, a.k.a. tribal knowledge, to operate. Practical knowledge is what each individual professional knows in-practice and is able to perform, but isn't really documented anywhere. It may be about how hardware is configured, how applications are designed, or in some cases, it involves information about historical decisions. The issue with tribal knowledge is that it disappears from an organization when people move on.

Checklists are a great tool for keeping us on track. Surgeon Atul Gawande argues in The Checklist Manifesto: How to Get Things Right, that the simple checklist – perhaps one of the most basic organizational tools — can improve the effectiveness of teams and individuals performing complex tasks. When his team introduced a two-minute checklist to eight hospitals as part of a research study in 2008, deaths were reduced by almost half.

A crucial piece of building a cyber resilient organization is taking a risk-based approach to decision making. You need to balance risk against rewards, and manage cybersecurity risk in a way that is consistent with your organization’s objectives. Having an effective Risk Management Program can ensure your organization’s resilience.

Even more than five years later, the Target breach is still one of the top 10 data breaches of the 21st century. It was also a watershed moment for cybersecurity. Not only did it shine a spotlight on payment card security, it also brought to light the idea that third-party vendors are a potential cybersecurity risk that organizations need to consider.
