Security News > 2020 > November > Quantum computers: How to prepare for this great threat to information security
Quantum computers also pose a big security problem.
That's because quantum computers don't just pose a threat to tomorrow's sensitive information: they'll be able to decrypt data that has been encrypted in the past, that's being encrypted in the present, and that will be encrypted in the future.
For governments, a quantum attack could mean a hostile state gains access to sensitive information, compromising state security or revealing secrets that undermine political stability.
Begin by promoting quantum literacy within your business to ensure that executive teams understand the severity and immediacy of the security threat.
How flexible is your current security infrastructure? How crypto-agile are your cryptography solutions? In order to migrate to new technology, do you need to rewrite everything, or could you make some straightforward switches?
