@ChiamzyNorah @RealTryHackMe Day 30 Mission Complete✅ What a journey! This challenge stretched me, tested me, and grew me.🚀 Shoutout to @ChiamzyNorah and everyone who inspired & supported me—community makes the journey worthwhile. 💙 Remember: networking is the backbone of cybersecurity. Keep learning!

We go live in 4 hours 51 minutes. See you there : ) Tell a friend to tell a friend.

@ChiamzyNorah @RealTryHackMe Day 29 of #30DaysNetworkingChallenge Final Project: Designed & implemented a 3-floor hotel network 🏨 ▪️VLANs per department ▪️Inter-VLAN routing (router-on-a-stick + OSPF) ▪️DHCP on routers for dynamic IPs ▪️Wireless access on each floor 📡 ▪️SSH for secure remote login 🔐

@ChiamzyNorah @RealTryHackMe Day 28 of #30DaysNetworkingChallenge Dove into a CTF-style room on @RealTryHackMe : Blue 💻 ▪️Recon → found SMB port 445 open ▪️Exploited EternalBlue (MS17-010) via Metasploit ▪️Upgraded to Meterpreter for persistence ▪️Cracked password hashes & captured flags 🏁 @ChiamzyNorah

@ChiamzyNorah @RealTryHackMe Day 27 of #30DaysNetworkingChallenge Jumped into Python for Network Automation 🐍⚡ ▪️Set up Python + VS Code ▪️Learned variables, data types, lists & dictionaries ▪️Explored loops, conditionals & functions ▪️Played with string formatting (f-strings >concatenation) @ChiamzyNorah

@ChiamzyNorah @RealTryHackMe Day 26 of #30DaysNetworkingChallenge Dived into network hardening on @RealTryHackMe ▪️Patching & disabling unused services 🛠 ▪️Least privilege + secure creds 🔑 ▪️VPN hardening (MFA + strong encryption) 🌐 ▪️Firewalls & monitoring to shrink attack surface 🚫 @ChiamzyNorah

@ChiamzyNorah @RealTryHackMe Day 25 of #30DaysNetworkingChallenge Today was a follow-along session exploring network monitoring basics. 🔍 Used Nmap for practical scanning 📡 Paired with Wireshark to visualize packet activity ✅ Hands-on: discovering hosts, open ports, and verifying traffic @ChiamzyNorah

@ChiamzyNorah @RealTryHackMe Day 24 #30DaysNetworkingChallenge 🔹Built a site-to-site IPsec VPN in Cisco Packet Tracer 🌐 🔹Prepped with OSPF, then enabled security K9 🛠️ 🔹Configured ACLs 🔹Set up IKE Phase 1 & 2 (AES-256, PSK) 🔑 🔹Applied crypto maps → encrypted tunnel ✅ @ChiamzyNorah

@ChiamzyNorah @RealTryHackMe Day 23 #30DaysNetworkingChallenge IDS/IPS & Firewalls @RealTryHackMe IDS = Detect 🚨 | IPS = Detect + Block 🛡️Signature vs anomaly-based detection. Hands-on: packet analysis, port scans, evasion w/ Nmap & Netcat Evasion: spoofing, fragmentation, port hopping & tunneling Firewalls

@ChiamzyNorah Day 22 of #30DaysNetworkingChallenge Dove into Network Security Basics on @RealTryHackMe 🔐 Explored hardware vs software defenses 🛡️ Learned the Cyber Kill Chain framework 🖥️ Hands-on: scanned with Nmap, exploited FTP anonymous login, SSH’d into a Linux box @ChiamzyNorah

@ChiamzyNorah Day 21 #30DaysNetworkingChallenge Follow-along: troubleshooting EtherChannel on switches. ✅ Checked physical links + trunk mode ✅ Aligned channel-groups ✅ Standardized on LACP 🔎 Verified with show etherchannel summary & show interfaces trunk → stable bundles @ChiamzyNorah

@ChiamzyNorah Day 20 #30DaysNetworkingChallenge Built a redundant switched network in Packet Tracer & explored Spanning Tree Protocol (STP) 🌉 Preventing loops with blocked ports 🏆 Root bridge election via Bridge ID 📊 show spanning-tree for port roles ⚙️ Path cost & port priority decisions

@ChiamzyNorah Day 19 of #30DaysNetworkingChallenge Built a wireless + wired lab in Packet Tracer: 📡 Configured a WRT300N router as DHCP 💻 Installed wireless NICs on laptops 🔐 Secured Wi-Fi with WPA2-PSK (AES) 🔌 Integrated a wired PC ✅ Verified with ping test @ChiamzyNorah #networksecurity

@ChiamzyNorah Day 18 #30DaysNetworkingChallenge Port Security in Cisco Packet Tracer By default, all switch ports are open — a potential invite to attackers. ✅ Configured static & sticky MAC address binding. ✅ Tested violation modes to block unauthorized devices. ✅ Security starts at Layer2

@ChiamzyNorah Day 17 #30DaysNetworkingChallenge Spanning Tree Protocol (STP) in action! 👑 Root bridge elected via lowest priority + MAC. 🚧 Ports move through Blocking → Listening → Learning → Forwarding. 🔧 Forced root bridge change by adjusting priority. 🛣 Link cost decides best path.

@ChiamzyNorah Day 16 #30DaysNetworkingChallenge Inter-VLAN Routing 1️⃣Router-on-a-stick – One router port, multiple subinterfaces, 802.1Q tagging, all VLANs talking through a single link. 2️⃣Layer 3 Switch – SVIs as gateways + ip routing = fast, hardware-based inter-VLAN communication.

When I finished my networking task for the day, I was completely drained and couldn't do other things in my "to-do-list". Burn out is real😫sometimes your body just needs rest. Let me go and do the needful before @AllenOracle comes for me…..
