Wrapped up the Intro. to Cybersecurity course on Cisco🎉 From threats to mitigation to the CIA triad, first milestone in dr. @ireteeh's mentorship, done and dusted 🙌🏽 #TeamApexG6 @ko_ceeherself @NwogodorPro2co @thedigitalmira @morak013 @PinkyQueen001 @Acyberstory @RootHawk_

I want to thank the interview team! @lady_sheraz @AleroLacherie Thank you!!! @ireteeh This opportunity will not be wasted, I assure you Ma❤️ @ChiamzyNorah Ma gee! We are in this together, one love!! Congratulations to all my Brothers and Sisters!!!💃🏽💃🏽

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 🔐

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

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

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

Day 23 #30DaysNetworkingChallenge IDS/IPS & Firewalls @tryhackme 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

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

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

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

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.

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.

Day 15 #30DaysNetworkingChallenge 🌐 Jumped into Layer 3 switching today. 🔄 Explored how it blends switching + routing for faster networks. 🛠 Practiced Inter-VLAN routing in Packet Tracer. 🏁Trunking carries multiple VLANs over one link 🔧 Resolved DHCP issues @ChiamzyNorah

Day 13 #30DaysNetworkingChallenge Basic firewall config in Cisco Packet Tracer 🔥 ✅ Blocked ICMP (ping) between PCs ✅ Allowed IP communication despite blocking ping ✅ Learned inbound rule setup & wildcard masks 💡 Firewalls can be protocol-specific, not all-or-nothing!
