Expert Insight:
- PoLP everything - making sure your users can do precisely what they’re supposed to do is key for your daily operations, including security. Too permissive and you’ll have a huge mess, too little and no one can work. Yes, preventing your users from adding new apps to your iDP as they pleased is also a big no no.
- Connect everything to your iDP - if it’s not connectable, then it’s unmanageable.
- Advanced MFA - using 2FA such as emails, OTP or text messages is so 2018 and could be easily abused. Use FIDO2 such as passkeys or external hardware devices (even native mobile devices!) to authenticate your users using advanced methods that are phishing resistant.
- Remove un-needed access to organizational apps - remember that user that last logged in to that app over a year ago? And it’s storing sensitive data? They don’t need access to it! Continuously monitor for stale app access as it might be your next potential breach.
- Well defined password policies can be the difference between Pwn to Own - leaked credentials, weak passwords and using the same password are the main reasons why threat actors are able to gain access to organizational accounts and data. Make sure to rotate users passwords every 90 days, using password managers, looking for leaked creds (yes, you can subscribe to HaveIbeenPwned.com) will enable you to minimize potential identity attacks.
