Network Security

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,…

What is Advanced Encryption Standard (AES)? The Advanced Encryption Standard (AES) is a widely used encryption algorithm designed to protect sensitive data. It is a symmetric key encryption algorithm, meaning the same key is used for both encrypting and decrypting data, as opposed to asymmetric key encryption, where different keys are used. AES is known…

What is threat hunting, and why is it important in cybersecurity? Threat hunting is a proactive approach to cybersecurity where analysts actively search for undetected threats lurking within an organization’s network. Unlike traditional threat detection, which relies on automated systems to alert teams about known threats, threat hunting focuses on finding advanced threats that evade…

What is an intrusion prevention system (IPS), and how does it work? An Intrusion Prevention System (IPS) is a cybersecurity tool designed to monitor network traffic and prevent unauthorized or malicious activity in real time. IPS solutions work by actively scanning incoming data packets, comparing their contents against a database of known threat signatures, behavioral…

What is privilege escalation? Privilege escalation is a cyberattack tactic where an attacker exploits vulnerabilities, misconfigurations, or weaknesses in a system to gain higher-level access than initially authorized. It enables attackers to perform actions or access data that would normally be restricted, increasing the potential impact of their attack. How Privilege Escalation Works Initial Access:…

What is ZTNA Security? ZTNA Security (Zero Trust Network Access Security) is a cybersecurity framework designed to provide secure and controlled access to an organization’s applications, data, and resources. It is based on the principle of “zero trust,” meaning no user or device is trusted by default, even if they are within the network perimeter.…

What is zero trust access control? Zero Trust Access Control is a security framework that operates on the principle of “never trust, always verify.” It requires strict identity verification for every user and device attempting to access resources, regardless of their location—whether inside or outside the network perimeter. Key Principles of Zero Trust Access Control:…

What does FortiNAC do? FortiNAC is designed to provide network visibility, device profiling, and policy enforcement to secure network access. However, its implementation and functionality face several technical challenges and limitations that can negatively impact its effectiveness: 1. Architecture and Deployment Challenges Out-of-Band Operation: FortiNAC operates out-of-band, avoiding inline network traffic processing. While this reduces…

Who owns Forescout? Forescout Technologies, a cybersecurity firm specializing in device visibility and control, is owned by private equity firms Advent International and Crosspoint Capital Partners. In July 2020, Advent International acquired Forescout in a revised deal valued at approximately $1.43 billion, with Crosspoint Capital Partners participating as a co-investor and advisor. What does Forescout…
