Since 2016 – when a hospital in Los Angeles paid US$17,000 (£14,000) to cure itself of an infection – the healthcare sector in particular and the world, in general, have suffered the effects of a sporadic outbreak of ransomware attacks. Though viruses and other strains of malware can cause headaches, data corruption, and financial losses, they tend to do so … Read More
A Closer Look at Multilevel Lattice Security Models
Organizations looking to regulate access to the information they routinely work with, and computer systems and communications networks seeking to preserve the confidentiality and integrity of the data they store or transmit will typically require some kind of formalized framework to govern how this is done. Information classifications such as Universal, Unclassified, Confidential, Secret, and Top Secret are one manifestation … Read More
What is Link Layer Encryption?
Network security is frequently implemented by considering the network as a series of layers, each dedicated to a particular function (data transport, applications, user interactions, etc.). This model has the underlying logic that, with several layers to have to work against, any potential attacker won’t find it easy to break through to the heart or kernel of the system, where … Read More
The Dangers of MaaS (Malware as a Service)
Information Technology has become a commodity in its own right. Virtually all aspects of IT are now available as some variant of the “XaaS” family, which includes Software as a Service (SaaS), Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and numerous others. They all save time, effort, and money for individuals or enterprise subscribers. And the advantages … Read More
Shift Row Transformation and Other Examples of Advanced Encryption
These days, we’re often warned about the dangers of hacking and data theft, or reminded of the need to protect our vital documents, sensitive information, and credentials by encryption, when they’re transmitted over the internet or an unprotected network. But what does that mean, exactly? Well, in simple terms, encryption is the process of taking a recognizable item (such as … Read More
What is Public Key Infrastructure (PKI) and How is it Used in Cybersecurity?
The process of encryption – the scrambling of information so that it can’t be readily understood, even if it’s intercepted in transit – is all very well as a standalone process for safeguarding the content of the data involved. But encryption is typically performed on documents and messages as a prelude to their transmission. And if the recipient of an … Read More

Cybersecurity Risk Assessment – Qualitative vs Quantitative Assessments
The overall security status of an organization is made up of inputs from the various business units which in turn make up the enterprise – such as Operations, Development, Finance, Audit, and Compliance. One way of establishing the contribution from each department is by assigning it a “risk status” on the basis of cybersecurity risk assessment performed on it over … Read More
The Evolving Role of Artificial Intelligence in Cybersecurity
It’s often been observed that technological advancement is a double-edged sword – and this is especially true in the realm of cybersecurity. Attackers have been known to use automation technology to stage and sustain their strikes – while those same machine learning algorithms and real-time response mechanisms can help enterprises that suffer an assault to speed up their efforts at … Read More
Anatomy of a TCP Sequence Prediction Attack
With so much of our business and personal lives relying on the transfer of information between points on the internet, it’s little wonder that cyber-criminals have long favored these connections as a target for their operations. Hijacking connections and/or intercepting data streams offers hackers a prime opportunity to extract valuable information assets, siphon off digital financial ones, or to interject … Read More
