What is a Man-in-the-Middle Attack
A man-in-the-middle attack lets adversaries intercept trusted connections -- from Wi-Fi logins to CI/CD package fetches -- with real-world cases and defenses.
Types of Vulnerability Assessments and When to Use Each
Network, host, application, database, wireless, and cloud assessments each answer a different question. Knowing which type fits which risk is half the job.
What Is TLS? Transport Layer Security Explained
TLS is the protocol that encrypts data in transit across the internet, turning the padlock in your browser into real protection against eavesdropping and tampering.
Tools in Cyber Security: A Starter Map by Category
The tools in cyber security span network defense, application security, identity, and data protection, and the fastest way to get oriented is a map by category rather than a vendor list.
Migrating VPN to Zero Trust: Supply Chain
A phased playbook for retiring corporate VPN concentrators in favor of zero trust network access, with specific guidance for protecting software supply chain pipelines.
What is Zero Trust Security
Zero trust means never trusting a user, device, or workload by default. Here's what NIST 800-207 actually requires, why it applies to supply chains too.
Automated Network Security: What to Automate First
Automated network security works best when teams target the repetitive, high-volume tasks first, patch verification, config drift detection, alert triage, rather than trying to automate everything at once.
Lateral movement
A precise breakdown of what lateral movement is, the MITRE ATT&CK techniques and pivoting methods attackers use, and how to detect them before they spread.
What is Egress Filtering in CI
Egress filtering in CI restricts where build jobs can send traffic, so a compromised dependency can't exfiltrate your secrets. Here's how to roll it out without breaking builds.
What is a VPN
A plain-English breakdown of what a VPN is, how it encrypts traffic, and why VPN gateways have become one of the most exploited attack surfaces in enterprise networks.
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.
