Who this course is for

What the 6 lessons cover

  1. Think like a defender. Most breaches come through four boring routes: a guessed or reused password, an unpatched system, a tricked person and a service left open. Defence has a shape: know what you have, reduce exposure, patch, watch, and be able to recover.
  2. The attacks you will actually meet. Phishing (including fake bank SMS and WhatsApp code requests), business email compromise, password spraying and credential stuffing, malware from cracked software, ransomware and social engineering. Payment instructions are confirmed on a known phone number.
  3. Hardening a network: the controls that carry the weight. Five controls carry the weight: multi-factor authentication on email first, patching, least privilege, segmentation such as a separate guest Wi-Fi, and nothing exposed that does not need to be, such as remote desktop or default CCTV passwords.
  4. Watching: logs, monitoring and knowing you were breached. Log sign-ins, failed attempts, admin actions and edge traffic, keep logs off the machine, test the alert path end to end, and respond in four steps: contain, assess, eradicate and recover, learn.
  5. The human layer and the law. Specific rules, rewarding reports and simulated phishing work better than lectures, and punishing a click hides the next one. PECA 2016 makes testing a system without written permission a crime.
  6. The security career from here. Security is rarely a first job: most people arrive from IT support, networking or development. Practise in a home lab, audit a real small office, and write up what you fixed.

Try the first exercise (in Urdu)

ایک ایسے network کی فہرست بنائیں جس کے آپ ذمہ دار ہیں — گھر، خاندانی دکان، آپ کے اپنے devices۔ اس پر ہر device لکھیں (networking-basics والی router کی client list انہیں دکھاتی ہے)، باہر سے پہنچنے کے قابل ہر service، اور admin حقوق والا ہر account۔ زیادہ تر لوگوں کو کم از کم ایک چیز ملتی ہے جو وہ بھول چکے تھے۔ یہی حیرت سبق ہے۔
