BYOD Risks
BYOD risk literacy — data mixing, privacy, wipe scope, jailbreak — enterprise policy reading on $MOB_LAB.
Visual · t27_byod_risks
BYOD = named risk tradeoffs. Policy literacy. $MOB_LAB. Original Cyberlium.
Opening
BYOD trades convenience for blurred boundaries — name the risks defenders document before anyone enrolls a personal phone.
BYOD risk literacy: corporate data on personal devices, personal apps accessing work tokens, incomplete wipe (selective vs full), jailbreak/root on personal hardware, privacy expectations vs IT visibility, lost device without reporting, shadow IT sideload. Defenders: user enrollment, app-level protection (MAM), DLP, conditional access, clear acceptable-use policy. Cyberlium policy review on $MOB_LAB — NOT coercing employees to install MDM without disclosure, NOT wiping personal photos without policy authority, NOT BYOD 'tests' on stranger phones. Lab row: five BYOD risks with one control each and privacy note.
1. Named BYOD risks
Data mixing, token leakage, jailbreak on personal device, selective wipe gaps, shadow sideload — five rows.
Link jailbreak Module 6 implications to BYOD conditional access.

BYOD risks: personal apps + corporate data on same device
controls: work profile / managed app config / conditional access
privacy: separate corp container vs personal photos/messages
never: enroll stranger personal phones or exfiltrate MDM tokens

2. Defender controls
MAM containerization, conditional access, DLP, user enrollment privacy tiers, incident lost-device playbook.
Policy must disclose visibility — ethics parallel Module 9 responsible scope.
3. Refused
No BYOD enrollment experiments on people without informed consent.
No full wipe of personal device outside documented policy authority.
4. What you ship: BYOD risk table
Five risks + control + privacy note + NEVER non-consensual enrollment line.
5. What you record before the next lesson
BYOD risk table path.
6. Wrong vs right: stranger phones vs lab emulator apps
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
Wrong
Force roommate BYOD enrollment without explaining IT visibility scope.
Right
BYOD risk table from $MOB_LAB policy review. Next: Enterprise Controls.
Mission: BYOD risk table
1) List five BYOD risks. 2) One control per risk. 3) Privacy disclosure note. 4) Write NEVER non-consensual enrollment.
