𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 > 𝗕𝗿𝗮𝗻𝗱𝗶𝗻𝗴 Most founders spend $10k on branding and $0 on security. Then wonder why data ends up on the dark web. Branding won’t stop breaches. Security will. 🛡️ Check SSL. Update plugins. Use 2FA. Are you protected or just lucky?

𝗪𝗶𝗻𝗱𝗼𝘄𝘀 𝗘𝘃𝗲𝗻𝘁 𝗟𝗼𝗴𝘀 ~ 𝗖𝗿𝗶𝘁𝗶𝗰𝗮𝗹 𝗜𝗗s Start with these three: • 4624 / 4625 → Successful / Failed logon • 4688 → Process created (what ran?) • 4720 → User account created (persistence?) Know them by heart. They’re your eyes into Windows activity.

𝗖𝗼𝘂𝗿𝗮𝗴𝗲 ~ 𝗦𝘁𝗲𝗽 𝗙𝗼𝗿𝘄𝗮𝗿𝗱 No one else will risk for you. Apply. Ask. Speak. Build. Action beats fear every time. One bold move today changes tomorrow. Your career is waiting go meet it.

𝗡𝗲𝘁𝘄𝗼𝗿𝗸𝗶𝗻𝗴 ~ 𝗧𝗵𝗲 𝗠𝗶𝘀𝘀𝗶𝗻𝗴 𝗣𝗶𝗲𝗰𝗲 Jumping straight into security tools without networking knowledge is a trap. Understanding how devices communicate lets you: • Make sense of alerts • Read logs accurately • Investigate incidents faster

NAT isn’t magic it maps private IPs to public ones. Types: •Static NAT → one-to-one mapping •Dynamic NAT → pools of addresses •PAT (Port Address Translation) → many-to-one mapping NAT hides internal IPs from the internet.

Sent out a job application into the void two weeks ago. Followed up today. It feels awkward, but what's the worst that can happen? Silence? It was already silent. Be politely persistent.

𝗗𝗮𝘆 12 | 𝗡𝗲𝘁𝘄𝗼𝗿𝗸 𝗧𝘆𝗽𝗲𝘀 𝗠𝗶𝗻𝗱𝘀𝗲𝘁 (𝗦𝗢𝗖 | 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴) Networks don’t just connect devices. They define scope and reach. • LAN = local office/home • WAN = wide-area connections • MAN = city-level networks • PAN = personal device networks I’m comparing types daily. Context > complexity.

𝗗𝗮𝘆 10 | 𝗪𝗶𝗿𝗲𝘀𝗵𝗮𝗿𝗸 𝗠𝗶𝗻𝗱𝘀𝗲𝘁 (𝗦𝗢𝗖 | 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴) Packets don’t lie. They tell stories if you listen. • Capture network traffic • Read TCP handshakes • Filter relevant packets • Identify anomalies and threats I’m dissecting traffic step by step. Observation > assumption.

𝗗𝗮𝘆 9 | 𝗣𝗼𝗿𝘁𝘀 & 𝗣𝗿𝗼𝘁𝗼𝗰𝗼𝗹𝘀 𝗠𝗶𝗻𝗱𝘀𝗲𝘁 (𝗦𝗢𝗖 | 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴) Ports don’t just allow traffic. They reveal intent. • TCP vs UDP differences • Common ports (HTTP, HTTPS, FTP, SSH, DNS, SMTP) • Analyze connections for unusual behavior • Map traffic patterns to services

𝗡𝗲𝘁𝘄𝗼𝗿𝗸𝗶𝗻𝗴 𝗕𝗮𝘀𝗶𝗰𝘀 𝗠𝗶𝗻𝗱𝘀𝗲𝘁 (𝗦𝗢𝗖 | 𝗟𝗲𝗮𝗿𝗻𝗶𝗻𝗴) Tools don’t explain traffic. They visualize it. • Learn how packets move • Understand IPs before alerts • Know ports before assumptions • Read logs before dashboards I’m learning this step by step. Clarity comes before confidence.

Python isn’t hard. It’s just misunderstood. Most beginners fail because they jump to libraries too early. Learn this order instead: • Variables → store ideas • Loops → repeat logic • Functions → reuse thinking • Lists & dicts → real data Master basics first. Speed comes later.

𝗠𝗼𝗯𝗶𝗹𝗲 𝗙𝗼𝗿𝗲𝗻𝘀𝗶𝗰𝘀 𝗠𝗶𝗻𝗱𝘀𝗲𝘁 (𝗨𝗙𝗘𝗗) Tools don’t create truth. They preserve it. • Extract mobile data at depth • Recover deleted artifacts • Verify integrity with hashing • Produce defensible reports Forensics isn’t breaking devices. It’s proving facts clearly, repeatably, in court.

Where is the lie? 😂 😆

Had a mock interview today and fumbled the "tell me about yourself" question. It happens! The trick is to have a simple story: "Here's what I did before, here's what I'm learning now, here's why I'm excited about this role." Practice it in the mirror.

𝗗𝗮𝘆 6/30 ~ 𝗗𝗡𝗦 𝗠𝗶𝗻𝗱𝘀𝗲𝘁🧵 If DNS fails, everything feels broken. • Name → IP • A, AAAA, CNAME, MX ↓ Most “internet down” tickets = DNS. Always test DNS first.
