Open Google Drive on web based browser like Chrome
On each of the folders if you see a person symbol it’s shared, if you don’t see the symbol its not shared
For each folder -> click SHARE -> Advanced -> Check which user has view rights and which user has edit rights -> Disable options to download, print, and copy for commenters and viewers -> Prevent editors from changing access and adding new people.
For each folder -> click SHARE -> Advanced -> SHARE SETTINGS -> Change -> Check settings there are 4 to 5 options
Note -> Even if your folder is not shared, files inside it can be in shared mode – This seems to be a big missing feature in Google Drive. There is no clear way to check this in one go for all files and we individually need to check each file. Workaround: Write Java code using Google Developers API to check this: https://developers.google.com/drive/
Android security settings to explore:
Emergency info – Settings -> Users -> Emergency info -> INFO & CONTACT – Note: Can be seen on locked screen
Settings -> Security -> Screen Lock
Encryption ON – at-least Android 6 required, by default it’s on from 6/7 onward – Settings -> Security
Setup OTP and recovery emails for all your accounts
Check permissions that various apps have on your phone
When you get an option – TRUST THIS DEVICE in Gmail or similar accounts, only select this option on your personal devices not public devices
Keep your desktop, laptop & mobiles password protected & encrypted if possible
Use standard Anti-Virus like McAfee, Windows Defender, Symantec, Norton, etc. Note: Android phones also have anti-virus
Explore and use a good VPN service
Go to your ACCOUNT settings regularly in Linkedin, Facebook, Gmail, etc. and see the logged in sessions (Who is using your account) and check which apps are integrated with your account, what information they are taking out – typically they take your friend’s list / relatives, age, email, phone number, etc.
Learn to backup your data in Cloud or external Hard Disk or both
Setup locate your phone, remote wipe, virus scan, link check, capture pic on wrong password attempts, etc. especially on Android via Anti-Virus or other means.
Update your devices across laptop, desktop and mobiles regularly using the official update process
Do not root your mobile devices
In Android don’t switch on the feature to TRUST UNKNOWN APPS to install APKs. Always install APPs from Android Play Store and Apple App Store only
Keep Bluetooth, WIFI, NFC off when not in use
When you leave your home switch off your WIFI
Change your passwords of WIFI, emails, accounts once in 6 months at-least. Your WIFI at home via router should be on encrypted network not non-encrypted, check the ADMIN page. Change the ADMIN password of your router at home, mostly many don’t change the username/password from admin/admin which is an easy entry point for wrong use. Update your router software also regularly via the official update option
For storing your passwords either use a diary / notebook OR there are encrypted software like password managers / wallets which store your passwords safely as an APP in your mobile – use them. See their ratings in PLAY STORE / APP STORE and then install or use. Don’t store passwords in plain text on computer or mobile.
Don’t keep same passwords across all your accounts – if you do so and one gets compromised all others get compromised
