Intro to Log Analysis! Logs are essentially time sequenced records of events across a network. Learning how to parse them to understand what actually happened during an incident is key.

Broken Access Control!
Once an attacker bypasses authorization controls, privilege escalation usually happens in one of two directionsβ Vertical or Horizontal.

Broken Access Control Introduction!
Before diving into attacks, Task 1 breaks down how systems determine whether to grant or deny access to a resource. Here is my study recap
#CyberSecurity #AppSec #OWASP
Day98 #200Dayschallenge @scriptedwebb
Dive into the raw HTTP access logs and spotted the exact attack sequence from IP 203.0.113.45
Brute Force: Multiple 401 failures on the admin user, trying passwords like 'admin123', 'password' and 'letmein'.

Instead of brute forcing the password, I registered a new account with the username aDmiN.

I completed a Portswigger lab where I was able to retrieve data from a user table with the table username and password, after which I was able to probe further to get administrator login details.

Windows Logging for SOC, I analyzed raw authentication logs to track a live intrusion. Here's what I did, launched the raw Practice Security.evtx' file on the VM's desktop. This simulates working on forensic data outside of a full SIEM.

π Day 128-129 β #Upskill_with_Dishank #200DaysChallenge
β
System Design β Database Connection Pooling
β’ Why a single shared connection becomes a bottleneck by serializing queries
β’ Why creating a new DB connection per request can exhaust backend ports and database resources
β’ PostgreSQL uses a process-per-connection architecture, so every connection requires OS resources like CPU, memory and process/file-descriptor resources
β’ Connection pooling keeps a finite number of reusable connections
β’ Borrow β Query β Return β Reuse
β’ Pool size is a tuning problem: too small β waiting, too large β DB contention
β’ In horizontally scaled systems, total DB connections multiply across instances
β
DSA @LeetCode Daily problems: Greedy + Bit Manipulation
β
Key takeaway:
In system design, performance is often about controlling shared resources rather than simply adding more of them.

When you're doing incident response, speed matters. Being comfortable in the CLI lets you grab system info, check running process and trace connections way faster than clicking through menus

Just completed OverTheWire Bandit Levels 11β21!
It wasn't easy as a beginner still learning Linux commands. I used AI as a learning guide, but I made sure I understood what each command does instead of blindly copying commands.
