DAY 68

Went deeper into routing today.

Learned how routers use routing information to choose paths and how packets move through multiple hops toward their destination.

Also explored how congestion can increase latency, cause packet loss, and slow down communication.

DAY 67

Learned about network congestion and how routers choose paths for packets to reach their destination.

Also understood that congestion can cause delays, packet loss, and slower communication.

DAY 66

Went deeper into Broadcast Domains and the ARP process today.

Also went through ARP step by step and how devices find the MAC address associated with an IPv4 address.

Today was a slow day.

I didn’t study anything new or make significant technical progress. No fake progress. Just keeping the streak alive.

DAY 65

Very light day today.

Just got introduced to monitor mode in wireless adapters and how it can be used to capture wireless traffic. Didn't study much, so I'll come back to this topic properly later.

DAY 63

Got introduced to broadcast domains today.

Learned what a broadcast domain is and how broadcast traffic stays within a network.

Also saw how routers separate broadcast domains and why this matters when designing larger networks.

DAY 62

Learned about ARP today and how it maps an IP address to a MAC address on the local network.

Another piece of the puzzle connecting IP, MAC, and Ethernet together.

DAY 61

Got introduced to Nikto today.

Explored how it can scan web servers and help identify potential vulnerabilities, misconfigurations, and outdated components.

Another tool added to my cybersecurity toolkit.

DAY 60

Back to Cybersecurity + Networking.

Started exploring Wireshark, filtering packets, and checking DNS requests to see network traffic in action.

Finally getting to see what's happening behind the scenes.

DAY 58 & 59

Continued building the college event website today and spent some time recalling the cybersecurity concepts I've covered so far.

Not a heavy learning day, but getting back on track. Will continue the proper learning path soon.

DAY 55

Continued Cisco Networking today.

Went deeper into NAT and got introduced to PDU
PDU isn't fully clear yet, so that's tomorrow's topic.

DAY 54

Got introduced to Splunk today and explored how it works at a high level.

Learned how it collects and analyzes logs to help security teams monitor activity and spot suspicious events.

Just the basics, but it connects well with SIEM.

DAY 53

Went deeper into NAT, gateways, switches, and servers today.

Understood how gateways and NAT differ, how switches use MAC addresses, and how a normal PC can act as a server.

Also connected it to AI ,why GPUs are important for heavy workloads.

DAY 52

Back to networking today.

Went deeper into DHCP and the DORA process, and understood the role of the default gateway.

Also revised private IPv4 ranges and IPv4 classes, and practiced DHCP configuration in Packet Tracer.
