Security / iam Dark mode The Principle of Least Privilege The principle of least privilege (granting every identity only the minimum access it needs to do its job) is one of the simplest ideas in security and one of the most violated. It says that every identity, whether a person, a device, an application, or […]
Security / iam Dark mode RBAC vs ABAC: Which Access Model to Use Every system that controls who can do what has to answer one question: on what basis do we grant access? The two dominant answers are RBAC and ABAC. Role-based access control decides by who you are. Attribute-based access control decides by who […]
Security / understanding risk Dark mode Risk Scoring: Likelihood, Impact, and the Matrix Every risk decision comes down to two questions: how likely is this, and how much would it hurt. Risk scoring is the discipline of answering both in a way that lets you compare one risk against another and decide where to spend […]

Security / ransomware Dark mode Ransomware Response Playbook: The First Hours When a ransomware attack is live, improvising is often the costliest thing you can do. There is a right order to the response, and most of the damage that turns a contained incident into a company-wide disaster happens in the first hour, when people […]
Security / ransomware Dark mode Ransomware Backup and Recovery Strategy When ransomware succeeds, backups are what stand between a bad week and a closed business. But the old advice to “keep backups” is often no longer enough, because modern attackers commonly go looking for your backups and destroy them before they encrypt anything. A backup […]
Security / ransomware Dark mode Ransomware Prevention: The Controls That Work There is no magic box that stops ransomware. Prevention works the way the attack does: in stages. Each control you put in place removes a step the attacker depends on, and enough of them in sequence break the chain before encryption ever happens. Zero […]
Security / ransomware Dark mode How Does Ransomware Work? The Attack Chain Modern ransomware is not a single moment when files lock up. It is the last step of a planned operation that often runs for days or weeks before anyone sees a ransom note. Understanding that chain, from the first foothold to the final […]
Security / incident response Dark mode Incident Response Tabletop Exercises A plan you have never tested is a hypothesis. A tabletop exercise (a discussion-based drill where the team talks through a scenario with no live systems touched) is how you test it. The team gathers, someone reads out a realistic incident scenario, and everyone talks […]
