Navigating the Evolution of Cybersecurity: Understanding the Transition from NIST CSF 1.0 to CSF 2.02/28/2024 The landscape of cybersecurity is constantly evolving, challenging organizations to adapt and enhance their security measures. The National Institute of Standards and Technology's Cybersecurity Framework (NIST CSF) has been a pivotal guide in this journey. With the release of CSF 2.0, significant advancements have been made, building upon the foundation laid by CSF 1.0. In this blog post, we will explore the key differences and improvements brought by CSF 2.0, focusing on its scope, focus, structure, and additional features.

In 2023, the cybersecurity world witnessed a diverse array of sophisticated threats. From credential stuffing to ransomware, and nation-state attacks, the landscape has evolved rapidly, presenting new challenges for businesses and individuals alike. This post delves into some of the year's most significant breaches, highlighting crucial lessons and strategies for a more secure future.
In the digital age, the importance of information security cannot be overstated. As we navigate the complex landscape of cybersecurity, one factor often stands out as both a potential risk and a line of defense: the human factor. This was the focus of my recent doctoral dissertation, where I explored the behavioral and cross-cultural factors that influence an individual's intention to comply with information security policies. It is well known that humans are the weakest link in the information security chain, but specifically, who are them? Well, you may guess, “they” are everyone. I have been in both sides, as a user and as a system admin; and in both sceneries humans tend to make mistakes. It’s human nature.
Blended Learning: An Alternative for Undergraduate Anatomy Teaching in Developing Countries3/16/2018 Anatomy, the study of tissues, organs and systems in the body, is an essential component in the curricula of many health professions. Due to curricular design, complexity of the learning material, and time devoted to teaching, anatomy learning could be compromised. Anatomy instructors and educational institutions must look for ways to complement anatomy teaching in order to better prepare students for what they will find at both, the graduate level and the work environment. In this review, we compared multiple approaches for anatomy teaching, and blended learning appears to give better results for contents comprehension, retention, and academic development.
The objective of this research was to develop a framework for understanding the Convergence of Cloud Computing, Machine Learning, and Internet of Things as the future of Decision Support Systems. To develop this framework, the researchers analyzed and synthesized 35 research articles from 2006 to 2017. The results indicated that when the data is massive, it is necessary to use computational algorithms and complex analytical techniques. The Internet of Things, in combination with the large accumulation of data and data mining, improves the learning of automatic intelligence for business. This is due to the fact that the technology has the intelligence to infer and provide solutions based on past experiences and past events. In the last decade of the proliferation of the World Wide Web, there has been a shift from normal human combat warfare to electronic warfare, where a person with a computer can do more damage to the infrastructure of a country than thousands of soldiers. The amount of data, intelligence, and damage generated by such warfare is astronomical. This type of warfare requires artificial intelligence and Expert Systems to go to the forefront of the battlefield in order to analyze data and trends to identify potential attacks and provide countermeasures to such attack. AI has put in a new perspective how Decision Support Systems (DSS) improve defense. DSS implemented today are in place to stop and deter in the shortest possible amount of time a cyberattack, and assist cyber defenders in finding the correct response. WannaCry or Wanna Decrytor ransomware is an informatic virus that attacks Windows operating system based computers primarily (including servers) by taking advantage of system vulnerabilities exploited by Eternalblue, a tool believed to be developed by the USA National Security Agency. What is the unique effect once infected by the virus? Well, you will notice it fast. The system will show you a Popup window letting you know that your computer is infected, all your files are encrypted, and for you to recover it all, they require a ransom payment using bitcoins. Unless you make the payment, all your files will stay encrypted. The worst thing about this virus is that, if you do not pay in a certain period, the ransom payment will keep rising.
But, wait! The intention of this article is not to create panic. Even though you should panic if your computer got infected and you didn't backed up your files recently (last day or night before the infection). Today more than ever, we are living in the interconnected and social era. Generation X and the famous Millennials, are so connected to the Internet, and spend so much time sharing almost everything about themselves, that they don’t imagine their life could go any other way. This is without online presence, in their social communities and networks, 24 hours a day, 7 days a week, 365 days a year.
