Public progress update
Weekly Status: July 1–7, 2026
Focused on Layer 1 and Layer 2 security, vulnerability analysis, defensive controls, and continued wargame practice.
weekly_status --public
This week moved from introductory security concepts into lower-layer network protections and practical attack-defense thinking.
student@dvcltr:~$ status --week module-02
./completed_this_week
- Continued wargame practice with Bandit or Natas.
- Studied physical layer and data link layer attacks and defenses.
- Worked on a vulnerability analysis assignment related to Layer 2 protections.
- Added module vocabulary through the glossary activity.

[COMPLETED] Layer 2 Security Vulnerability Analysis
Focus: Data Link Layer / Defensive Controls
Summary: Reviewed how lower-layer network protections can reduce exposure to common network threats.
What I learned: Security is not only an application-layer concern; weaknesses lower in the stack can affect the whole environment.
[COMPLETED] Layer 1 and Layer 2 Security Discussion
Focus: Physical and Data Link Layer Defense
Summary: Compared attack and defense ideas across the first two OSI layers.
What I learned: Effective defense requires matching controls to the layer where the risk appears.
[COMPLETED] Wargame Practice
Focus: Enumeration / Command-Line Practice
Summary: Continued solving security exercises through a wargame environment.
What I learned: Repetition helps build a more reliable workflow for investigating systems.

echo $BIGGEST_TAKEAWAY
The biggest takeaway this week was that network defenses need to be layered. Even basic infrastructure choices can influence whether later security controls are effective.
next --focus
- Review IP addressing and subnetting.
- Practice more command-line security exercises.
- Connect network-layer concepts to realistic defensive planning.
