100 Days. No shortcuts. No excuses.

From confusion to clarity, from failure to resilience — today I stand stronger, sharper, and certified by experience. Every late night, every setback, every lesson built this version of me.

Routing table. Router decides:
Same network? Send ARP. Find MAC. Deliver direct.
Different network? Send to next router.
No route? Send to default gateway.
ARP for local. Route for remote.

Day 64/100

As networks grow, keeping all devices on one network can cause congestion.

LAN segmentation helps:

▪️ Single segment: simple, low cost
▪️ Multiple segments: reduces broadcast traffic, improves performance

Smart network design = better performance.

MOU = Handshake. We agree to talk.
MOA = Contract. We agree to terms.
SLA = Promise. Here's what you get.

MOU starts. MOA makes real. SLA keeps honest.

Day 62/100

In Zero Trust Architecture (ZTA), Trust is a Vulnerability.

Key Concepts:
🔹 Never Trust, Always Verify
🔹 Micro-segmentation
🔹 Identity-Centric

Ditching broad access for Least Privilege.

Day 60 #100DaysOfCyberSecurity
Cryptography = turning your data into a secret code 🔐

It protects your passwords, messages, and online transactions from hackers.

Without it, apps like WhatsApp wouldn’t be safe to use.

Simple idea:
Encrypt (lock it) → Decrypt (unlock it)

[Victory Okechukwu @VictoryOkechuk3]

Day 59/100

Today I learned about routing tables and routing entries

Routers store network paths, not individual hosts
Routes can be static (manual) or dynamic (learned)
Default route forwards packets when the destination network is unknown

Day 46 of my #100DaysofCyberPH
I studied System configuration and it simply means setting up a computer, software, or network so it works properly and securely.

It includes things like adjusting settings, installing necessary software, and applying security controls.

Day 46 of the #100DaysofCyberPH

Today I explored the Application Layer — the layer that connects user applications to network services through protocols like HTTP, DNS, and FTP.

Day 45 of my #100DaysOfCyber with @phcybergiants

Today’s topic: “Theoretical Example: Code of Ethics” from ISC2.

In cybersecurity, technical skills are important, but ethics guide how those skills are used.

Key takeaway:
Cybersecurity professionals must always

Day 39/100 @phcybergiants

🔐 Network security isn’t just firewalls—it’s risk management. From secure architecture & encrypted traffic to monitoring, access control & policies, it’s about keeping data, systems, and business safe.

Day 42 of 100

I simulated a home network to automate IP management using Cisco Packet Tracer.

In the lab I;
✔ Set router IP to 192.168.5.1
✔ Configured DHCP pool (192.168.5.126, 75 users)
✔ Connected 3 PCs and enabled DHCP

Port 21 (FTP) sends your password in plain text. Anyone on the network can steal it.
Port 22 (SSH) encrypts everything. This is why we use secure alternatives.Port 23 (Telnet) still exists in 2026. #PHCyberGiants
