Why does it seem like more attacks are taking place?
Perhaps because more higher impact incidents are making the media these days. Perhaps there is an actual increase in threat actors, their activities, or the effectiveness of their activities. Perhaps the defenses have been spread too thin, perhaps … oh heck, perhaps all sorts of things. I know that in
Privilege Escalation and Trust
Privilege escalation has always been a problem in computers, and after all these years, we still don’t seem to have a handle on the issue. I think this is closely related to our lack of understanding and systematic deployment of trust models and the nature of trust. Non-zero trust One
Standard Deviation vs Standard Error: Clearing up the Confusion with Visual Examples
Standard deviation and standard error are two statistical measures that often get confused with each other. While both measures describe the variability in the data, they serve different purposes. Standard deviation measures the spread of the data. It calculates how far the individual data points deviate from the mean of
Generative AI and the abuse of social media
A new tactic appears to have arisen in the use of generative AI in social media. This tactic is comprised of rapidly generating seemingly knowledgeable responses to other people. One of the many challenges of this approach is that the generative AI is so lightweight in terms of understanding (It
Mastering Central Limit Theorem (CLT) with Intuitive Examples
Let’s explore the Central Limit Theorem (CLT) with an example of rolling two dice multiple times (let’s say 30 times). We will calculate the mean of the two dice values and plot its distribution to understand the CLT intuitively. Round 1: We roll the dice and get 2 and 5.
Why does a 20 year old have access to TS/SCI and what do we do about it?
This is not the first time a young person has had authorized access to substantial amounts oftop secret sensitive compartmented information (TS/SCI) and leaked it. How could thishappen? It’s easy to understand… What do 20-year old people do in the military? Among other things, they are in the field being
Demystifying Degrees of Freedom with Visual Examples: A Beginner’s Guide
The concept of degrees of freedom is essential in statistical analysis, and it is commonly used in various statistical tests. In this blog post, we will explore A) Without any restriction B) With a restriction C) Degrees of freedom in contingency tables D) Bessel’s correction with examples. This will help
A Beginner’s Guide to t-tests: Real-life Applications of t-test: One-Sample, Two Sample and Paired Sample t-test
William Sealy Gosset, an English statistician who was also a beer brewer, developed the t-test. He used this test to ensure the consistency and quality of the beer he produced. Gosset published his work under the pseudonym “Student”, which is why the t-test is also known as the Student’s t-test.
Basics of Blockchain Technology
Blockchain technology has gained popularity in recent times. This article covers some of the fundamental concepts associated with it, including: What is blockchain? Why do we need blockchain? How does blockchain ensure trust? Who invented it? When to use it? When not to use it? So, let’s get started. What
