Zero Day Malware: How It Works and How to Contain It
Zero day malware exploits unknown vulnerabilities before patches exist, making signature-based detection useless and forcing reliance on behaviour analysis.
Firewall Pulse Handbook Desk
The Firewall Pulse Handbook Desk is the part of the Firewall Pulse newsroom that covers reference guides that explain the ideas behind the headlines. It is a newsroom desk, not a single person. Sections: Guides. Guides are drafted with AI assistance, carry no invented statistics and are reviewed when the facts change. It has published 65 articles so far.

Cyber Attacks
Vishing Attack Meaning: How Voice Phishing Works and How to Stop It
Voice phishing exploits psychological urgency rather than software flaws, making technical controls alone insufficient for defence against social engineering.
Threat Intelligence
Detection Engineering Lifecycle: Build, Tune and Maintain Alerts
Detection engineering transforms raw telemetry into reliable signals by treating alerts as code that requires continuous validation and iterative refinement.
Vulnerabilities
Out-of-band patches: what small businesses need to know
Emergency updates bypass standard testing cycles, creating a high risk of system instability if applied without rigorous validation procedures.
Cyber Attacks
Man-in-the-Middle Attack Prevention Checklist for Secure Connections
Encrypting data at rest does not protect it while moving across networks, leaving sensitive information exposed to interception during transit.
Cloud Security
How CI/CD Pipeline Attacks Work: Step-by-Step Breakdown
Attackers target the build pipeline because it holds the keys to the kingdom, allowing them to plant malware before your security tools ever see the code.
Threat Intelligence
Implement Mean Time to Detect: A Step-by-Step Rollout Plan
Detecting threats faster requires mapping data sources to specific attacker actions, not just counting alerts from generic security tools.
Cyber Attacks
OAuth Consent Phishing: How the Attack Works and Where to Block It
Attackers bypass traditional security controls by tricking users into voluntarily handing over access tokens that legitimate applications would use.
Cyber Attacks
Build a Security Operations Center: A Practical Implementation Plan
Most teams fail because they buy tools before defining detection logic, creating alert fatigue that buries real threats under noise.
Threat Intelligence
Unified Kill Chain: The 10 Questions You Need Answered
The Unified Kill Chain exposes how traditional models miss the critical window where attackers operate inside trusted network segments before exfiltrating data.
Malware & Ransomware
Stop Mobile Malware: Practical Prevention That Actually Works
Relying on app stores alone fails because malware hides in legitimate apps that steal credentials before they reach security filters.
Vulnerabilities
Exposed Admin Panels: How Attackers Gain Access Step by Step
Most administrative interfaces remain accessible to the public internet because default configurations prioritise convenience over isolation, leaving the back door open.
Cloud Security
Implement Cloud Compliance: A Step-by-Step Guide for Secure Infrastructure
Compliance fails when teams treat it as a periodic audit rather than a continuous state enforced by automated policy checks at the infrastructure level.
Data Breaches
How Breach Notification Letters Work: The Hidden Mechanics
The notification letter is the final output of a legal and technical triage process that often begins weeks before you receive it, shaped by regulatory thresholds rather than pure impact.
Data Breaches
How to Stop Source Code Leaks Before They Happen
Most source code leaks occur not from external hacks, but from internal misconfigurations and unsecured developer environments that expose repositories to the public internet.
Malware & Ransomware
Disaster Recovery Plans: Definition, Purpose, and Execution Steps
A disaster recovery plan dictates how you restore systems after failure, distinct from the broader business continuity strategy that keeps operations running.
Cloud Security
How Cloud Backup Works: The Hidden Mechanics and Limits
Cloud backup relies on immutable storage objects and client-side encryption to prevent ransomware, but network latency and API rate limits dictate your actual recovery speed.
Threat Intelligence
Fast Flux DNS: How Attackers Hide Malware and How to Stop It
Fast flux networks obscure malicious infrastructure by rotating IP addresses faster than standard reputation systems can block them, creating a moving target for defenders.
Vulnerabilities
Least Privilege Access Checklist for Secure Systems
Removing unnecessary permissions breaks the chain of lateral movement, forcing attackers to compromise every single account individually rather than escalating from one foothold.
Malware & Ransomware
IoT Malware Risks: Practical Protection for Small Business Networks
Standard antivirus software cannot inspect the closed operating systems of most internet-connected devices, leaving a blind spot that attackers exploit to pivot into your main network.
Threat Intelligence
Threat Intelligence Sharing: How Collective Data Stops Attacks
Sharing indicators of compromise transforms isolated defensive data into a coordinated shield that reduces detection times across entire sectors without requiring direct operational control.
Cloud Security
How Workload Identity Works: The Mechanism Behind Cloud Service Auth
Workload identity replaces long-lived secrets with short-lived tokens, shifting the security boundary from credential storage to identity verification at runtime.
Data Breaches
Stop Unauthorized Access: Practical Controls That Actually Work
Most breaches succeed because attackers move laterally after initial entry, not because they bypass the outer perimeter.
Data Breaches
Leaked Source Code: How to Contain and Neutralise the Threat
Exposed code reveals internal logic and hidden credentials, turning standard defensive measures into predictable obstacles for attackers.
