What is an Intrusion Detection System (IDS)
An IDS detects malicious network or host activity after it happens. Learn what an IDS is, how it differs from an IPS, and why supply chain attacks need more.
What is an Intrusion Prevention System (IPS)
An IPS blocks malicious traffic inline in real time, but it can't stop supply chain attacks hidden inside trusted code and dependencies.
How to implement zero trust network architecture
A practical, step-by-step guide to implement zero trust network architecture: identity, microsegmentation, posture checks, policy-as-code, and verification.
How to set up a bastion host for secure SSH access
A step-by-step guide to set up bastion host SSH access on AWS, with ProxyJump configs, security group rules, and a verification checklist for hardened jump box access.
How to configure Nessus for vulnerability scanning
A step-by-step guide to installing Nessus, building scan policies, defining safe targets, and validating results — plus where supply chain risk starts beyond the network scan.
How to configure DNSSEC
A practical, command-by-command guide to configure DNSSEC on managed and self-hosted DNS, verify the chain of trust, and prevent DNS spoofing across your supply chain.
