We read this week of malicious apps being available on the accredited app stores, that would steal personal data including contacts and photos.
Whilst this is rare, and the app stores try to block these malicious apps, it is yet another good reason to have a list of approved apps from which your staff and volunteers can freely choose.
This would normally be a part of your IT security or acceptable use policies. If we can help you to review yours, or even create them, then just get in touch.
