The to Reporting for Board

88% of boards now classify cybersecurity as a business risk.

But most CISOs still struggle to make cyber risk meaningful for the board.

The Pentera GOAT Guide is your playbook to:
✅ Report with confidence
✅ Use outcome-driven metrics
✅ Align security with business priorities

🧱 IPTables, Demystified — Linux Firewall Fundamentals for Blue Teams

If you’re in SysAdmin, DevSecOps, Cloud, SOC, or Network Security, this is core knowledge for traffic control, segmentation, and incident response on Linux hosts.

🧠 What the Guide Breaks Down

1️⃣ Firewall Architecture 101
External vs internal firewalls and where IPTables fits
Stateful inspection & connection tracking in plain language

2️⃣ How IPTables Is Structured
Tables: filter, nat, mangle, raw, security
Chains: INPUT, OUTPUT, FORWARD, etc.
How a packet actually travels through the kernel routing path

3️⃣ Building Real Rules (Not Just Copy-Paste)
Why a default DROP policy is your safest baseline
Letting only ESTABLISHED and RELATED traffic through
Handling loopback, DHCP, SSH, FTP/TFTP the right way
From zero to “basic firewall deployed & persistent”

4️⃣ Advanced Topics for Practitioners
Connection tracking with conntrack
Passive vs active FTP nuances
Tuning modules and limits (e.g. nf_conntrack_max, timeouts, NAT helpers)

Real-World Cybersecurity Scenario-Based Questions SOC

SOC Interviews Aren’t About Tools — They’re About Thinking Under Pressure

If you’re preparing for SOC Analyst interviews, this resource is gold. I came across a Scenario-Based Cybersecurity Interview Guide that uses the S.T.E.P. method (Situation → Triage → Evaluation → Prevention/Response) — and it perfectly reflects how real SOC work is assessed today.

This isn’t theory. It’s real-world incident thinking.

📘 What’s inside the guide:

🔐 Credential & Identity Attacks
• Suspicious foreign logins
• MFA fatigue attacks
• Azure AD / IAM compromise scenarios

🦠 Endpoint & Malware Incidents
• Obfuscated PowerShell via Office macros
• C2 beaconing & EDR response
• Post-exploitation detection

🔄 Lateral Movement & Privilege Abuse
• SMB / WMI attacks
• Kerberos anomalies & Mimikatz
• Domain admin misuse

📤 Data Exfiltration Scenarios
• HTTPS + DNS tunneling
• 7z staging & off-hours transfers
• DLP and egress control decisions

📧 Business Email Compromise (BEC)
• Mailbox rule abuse
• Auto-forwarding & vendor fraud
• SOC–Finance incident coordination

☁️ Cloud & Supply Chain Attacks
• Compromised IAM roles
• API abuse & cryptomining
• Malicious software updates

Methods for Stealing Passwords in Browser

The document provides details on tables and columns in the Chrome and Firefox browsers that may contain sensitive user information like saved passwords, browsing history, cookies, and more.

It lists the table names and relevant column names for Chrome and Firefox that could be used to extract passwords, browsing data, autofill form information, and other private browsing data from the browsers. The tables described contain a wealth of personal data that could be abused if improperly accessed.

Introducing Network Security

Network security isn’t just an IT responsibility anymore — it’s a business-critical priority.

From evolving threat vectors to hybrid-cloud complexity, the modern enterprise demands architecture, visibility, and resilience at a level never seen before.

That’s why we created this comprehensive Network Security Guide — a distilled view of frameworks, architectures, KPIs, governance models, and threat insights that every cybersecurity leader must keep on their radar.

Built using industry best practices and expert insights, this guide simplifies complexity so teams can build stronger, smarter, and future-ready network defenses.

📘 Explore the full guide and take a meaningful step toward stronger security maturity.

Linux Privilege Escalation

Linux Privilege Escalation — The Skill Every Cybersecurity Professional Must Master in 2025

I just reviewed one of the most comprehensive Linux PrivEsc guides I’ve seen and it’s packed with real techniques attackers actually use in real breaches. If you work in Red Teaming, Pentesting, Threat Hunting, SOC, DFIR or even Cloud this is the kind of knowledge that separates beginners from true professionals.

🧠 What the PDF Covers (and Why It Matters)

🔹 Deep Enumeration: kernel version, sudo rights, SUID/SGID binaries, environment variables, cronjobs, backups, hidden files, services, shells (pages 1–3)
🔹 Automated Enum: LinEnum, LinPEAS, enumy, linuxprivchecker (page 4)
🔹 Kernel Exploits: searchsploit + exploit suggester (page 4)
🔹 Weak Permissions Abuse: /etc/shadow, /etc/passwd, binary overwrites (pages 5–6)
🔹 Credential Harvesting: history grep, config leakage, memory dump tools like mimipenguin (page 6)
🔹 Docker & LXD Breakouts: mounting host FS, privilege containers (pages 7–8)
🔹 SUID/SGID Exploits: PATH hijacking, shared object injection, cron abuse (pages 9–10)
🔹 LD_PRELOAD / LD_LIBRARY_PATH attacks: hijacking libraries to spawn root shells (pages 11–13)
🔹 Python Module Hijacking: creating fake modules to escalate privileges (page 14)
🔹 GTFOBins techniques the ultimate misconfiguration weapon (multiple pages)
🔹 NFS no_root_squash exploitation (page 17)
🔹 Session Hijacking (screen/tmux) (pages 18–19)
🔹 Reverse Shell Hijacking (page 20)

This is not theory ✨ these are the exact paths attackers use after initial access. If you can’t detect or replicate them, you can’t defend against them.

My biggest takeaway:
Privilege escalation isn’t a toolset it’s a mindset of finding one misconfiguration that changes everything.
