What Happened As we’ve seen, a bug in a CrowdStrike update caused worldwide havoc. Approximately 8 million Windows computers crashed at many companies, from airlines to broadcast news to hospitals. Desperate users took to forums, some entire organizations ground to a halt, and some problems persisted for days and longer. While CrowdStrike was able to…

The Attack Begins The blip of a new email flashed on Cora’s screen. It was yet another alert from Core Audit, and it wasn’t the first one of the day. But a quick glance at the SQLs and adrenaline jolted her awake. It felt like caffeine was pumping directly into her brain. That is not…

We previously discussed data-centric security and the need for airtight defenses. Using IDS and IPS is a first step in that direction, but let’s take things further by creating overlapping controls that will tighten security much more. The risk-control matrix is at the core of security planning. The matrix maps our risks to the controls…

We previously discussed data-centric defenses as the critical last line of defense. As such, one of our requirements is to try and make it as airtight as possible. That’s not a minor or trivial requirement. In this article, we’ll discuss how we can get there. There are two concepts we’ll need to discuss: False negatives…

We often think of cybersecurity as made up of silos. There’s network security, training, physical security, email security, etc. Each silo usually includes multiple solutions. For example, network security includes firewalls, routers, VLANs, and similar measures that are not necessarily directly related. The problem with any issue comprised of many unrelated components is that it’s…

1. Why mask? Because we can’t protect the data outside of production: Imagine copying customer data for testing. How could you protect it after copying it? Without data masking, you will expose all names, addresses, phone numbers, emails, financial information, and more. Static masking replaces these values with good fakes so you can test without jeopardizing…

Recent polls of cybersecurity professionals show most respondents (82%) have partial or no visibility into their databases and need it. Few said they have good visibility (7%) or don’t need it (11%). The surveys were conducted in various LinkedIn groups in English and Spanish, asking: “Do you have visibility into what’s happening within your database?”.…

Anomaly analysis uses behavioral analysis, helping you save time while expanding your control to vast activity volumes. These capabilities are made possible by the unique security repository technology in Core Audit. The anomaly analysis engine dynamically creates behavioral profiles based on the activity captured by the security repository, allowing you to compare the present with…

One of the popular myths about security is that you can get it out of the box. Just install something, and voila! You’re magically secured. But that never works. Regardless of what you’re trying to secure, your first step should always be understanding the activity. You should know how the system is used, by whom,…

Many organizations design their cybersecurity strategy and decide what solutions to purchase based on industry trends and best practices. The outcome is often imbalanced and inappropriate to the organization’s risk profile and security needs. Best-practice implementations are usually one-size-fits-all and not tailored to the specific environment. Being predictable, there are usually tools and guides on…

On Sunday morning, we got an anomaly alert. It was March 19, 2023. This story is about what happened. Background The Blue Core Research website uses WordPress (a free and open-source content management system). WordPress usually uses MySQL as a backend database, and our installation is no different. While our WordPress doesn’t contain sensitive data,…

Introduction When I first heard the news, my first thought was – how can a hacker group breach so many systems across so many government agencies so quickly? My answer was simple: they cannot. The inevitable conclusion is that they have infiltrated the government systems for months, if not years, waiting for the time they…

Introduction SQL Injection is one of the most well-known attack vectors, and that’s largely because it poses a significant security challenge. The only way to understand the benefits and deficiencies of different solutions is by understanding the problem and the approach each solution has to solving it. The Problem The best way to understand the…
