πŸ¦‘ Troubleshooting OSPFv2 Neighbor Adjacencies Made Easy! πŸ› 
Are your OSPFv2 neighbors stuck in states like Init, 2-Way, or ExStart? Troubleshooting OSPF can be tricky, but with the right approach, you can resolve issues quickly! Here's a checklist to help:

βœ… 1. Check Network Types
Ensure both devices are on the same network type (Broadcast, Point-to-Point, Non-Broadcast, etc.). A mismatch could lead to adjacency issues.
βœ… 2. Verify Subnet Masks
Neighbors must share the same subnet. Run show ip ospf interface to confirm.
βœ… 3. Confirm Hello and Dead Timers
Default timers should match. Use show ip ospf neighbor to check compatibility.
βœ… 4. Authentication Configurations
Is OSPF authentication enabled? Double-check the keys and methods (Plaintext/MD5).
βœ… 5. MTU Mismatch
A mismatch in MTU can cause neighbors to get stuck in ExStart. Use ip ospf mtu-ignore if necessary.
βœ… 6. Router IDs
Each router must have a unique Router ID. Conflicts can disrupt adjacencies.
βœ… 7. Passive Interfaces
Is OSPF accidentally configured as passive on the neighbor-facing interface? Check your configs!
βœ… 8. Access-Lists or Firewalls
Ensure UDP packets on ports 520 and 89 aren't blocked by ACLs or firewalls.
Troubleshooting OSPF is all about systematic checks and leveraging show/debug commands. Here's my golden rule: Start from Layer 1 and move up!
πŸ’‘ What’s your go-to step when troubleshooting OSPF adjacencies?

πŸ¦‘The cyber skills gap isn't about talent.

It's about access. πŸ‘‡

The cybersecurity learning curve can feel steep.

But here's something many people don't know:

You can get world-class training without spending a dime.

1. Start with the Basics:

- Google's Cybersecurity Professional Certificate walks you through:
* cyber foundations
* risk management
* essential coding skills.
You'll master Linux, SQL, and Python basics in under 6 months.

- The ISC2 Certified in Cybersecurity program is a gem.
The training and certification exam are free - you only pay a $50 annual fee after passing.

2. Level Up with Technical Skills (hands-on practice):

- Security Blue Team offers 6 beginner-friendly courses with real demonstrations.
It's like having a mentor guide you through your first steps.

- TryHackMe and Hack The Box offer hands-on practice in real environments.
You'll learn by doing, not just watching.

3. Build Specialized Knowledge

- The Python Institute is there will elevate your scripting skills.

- The CompTIA Security+ prep materials cover core principles you'll need for entry-level positions.

- SANS teaches you practical basic security concepts.

4. Master Advanced Topics:

- Dive into defensive security and cyber risk management.

- Learn the NIST CSF framework and practical strategies.

- Learn OSINT for smart ways to gather and use public data for defense.

Pentesting is primarily concerned with identifying and exploiting vulnerabilities within a specific target system, striving to uncover as many weaknesses as possible.
This process aids in shoring up an organization's defenses by pinpointing areas of vulnerability.

On the other hand, a red team engagement shifts its focus. Instead of merely finding vulnerabilities, it aims to assess an organization's defensive capabilities by simulating real-world attacks.
The goal is to evaluate how well the organization can detect and respond to these simulated threat actors.

You will find below a list of resources for Red Teaming.
