What is Zero Standing Privileges (ZSP) in cybersecurity? Zero Standing Privileges (ZSP) is a modern security concept rooted in the principle of least privilege and just-in-time (JIT) access. At its core, ZSP eliminates persistent administrative or privileged access rights across an organization’s IT environment. Instead of users or service accounts having continuous elevated permissions—standing privileges—ZSP…

What is the ACME protocol and how does it work? The Automatic Certificate Management Environment (ACME) is a protocol developed by the Internet Security Research Group (ISRG), primarily to automate interactions between certificate authorities (CAs) and web servers. Its main goal is to streamline the process of obtaining, renewing, and revoking SSL/TLS certificates, thereby promoting…

What is firewall as a service (FWaaS)? Firewall as a Service (FWaaS) is a cloud-based network security model that provides firewall protection as a centralized, scalable service rather than through traditional on-premises hardware. FWaaS simplifies management, enhances security across distributed environments, and enables secure access from any location. How Firewall as a Service Works –…

What is SSH and How Does It Work? SSH, or Secure Shell, is a cryptographic network protocol that allows secure communication between devices over an unsecured network. Originally developed as a replacement for insecure login protocols like Telnet, SSH provides a secure channel through which users can log into another computer, transfer files, or run…

What is a bastion host and why is it used? A bastion host is a special-purpose computer on a network specifically designed and configured to withstand attacks. It typically serves as the single point of entry into a private network from the public internet, acting as a secure gateway that administrators can use to access…

What is the Automated Certificate Management Environment (ACME)? The Automated Certificate Management Environment (ACME) is a protocol designed to automate the process of obtaining, renewing, and managing SSL/TLS certificates from a certificate authority (CA). It is widely used to secure websites and services with encryption.   How ACME Works: Domain Validation: The ACME client proves…

What is FWaaS? Firewall as a Service (FWaaS) is a cloud-based security solution that delivers firewall functionality via the internet, rather than through traditional on-premises hardware. It provides centralized, scalable, and policy-driven protection for users, applications, and data—no matter where they’re located. Key Features of FWaaS: Cloud-Native Firewall Hosted in the cloud, removing the need…

Understanding Data Centric Security In an era where data breaches and cyber threats are increasingly sophisticated, the importance of data centric security (DCS) cannot be overstated. DCS is a transformative paradigm that shifts the focus from securing infrastructure—such as networks, servers, and applications—to securing the data itself. This approach ensures that data remains protected, irrespective…

What is cloud network security, and how does it work? Cloud network security refers to the practices, policies, technologies, and controls designed to protect cloud-based environments from cyber threats. As organizations increasingly migrate to cloud infrastructures—including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS)—securing network access, data,…

Introduction to Post Mortem Analysis In the dynamic field of cybersecurity, understanding and mitigating risks is a continuous endeavor. One of the most critical processes for this is the post mortem analysis. After a security breach, this structured review serves as an indispensable tool to dissect the incident thoroughly. It aims to illuminate the root…

Understanding User and Entity Behavior Analytics The importance of advanced analytical tools cannot be overstated. User and Entity Behavior Analytics (UEBA) is emerging as a cornerstone in contemporary network security strategies, offering a nuanced method to monitor and understand the actions of both users and devices within a network. UEBA’s strength lies in its ability…

Introduction to Sandboxing in Cybersecurity Cybersecurity threats are becoming increasingly sophisticated, requiring innovative strategies to safeguard sensitive data and systems. One effective method is sandboxing, a technique that runs code in an isolated environment to evaluate its behavior before it interacts with a live system. This approach has become a vital tool for cybersecurity professionals,…
