What you will practise in this chapter
- How to use cheat sheets for revision (not as attack recipes)
- Linux day-to-day commands on Amazon Linux (
sudo yum/sudo service) with Blue notes - MySQL connect / CRUD / SELECT / keys / GRANT / safe updates / backup awareness
- Nmap host discovery and gentle lab scans (
-T2) with OWN-IP ethics - Metasploit workflow awareness on Metasploitable only (detect / patch mindset)
- One combined revision card: situation → tool recall → Blue control
- Project Build-Hack-Fix + real incidents for scan / exposure hygiene
Lab scope
Cheat sheets list commands. Every offensive-looking flag means only systems you own: host-only VirtualBox (Kali 192.168.56.10, Metasploitable 192.168.56.20, DVWA/Juice 192.168.56.30–.50), your Free Tier EC2, or your emulator. Never Nmap a cafe Wi-Fi, never Metasploit a neighbour phone, never mysqldump a client production DB without written scope. IT Act sections such as 43 and 66 apply without authority (verify current text). Lab = learn. Production = defend. Sheets = revision, not permission.
