The greatest inherent risk when performing a disaster recovery plan (DRP) test is disruption to the production environment. A DRP test involves simulating a disaster scenario to ensure that the organization's plans are effective and that it is able to recover from an incident. However, this involves running tests on the production environment, which has the potential to disrupt the normal operations of the organization. This inherent risk can be mitigated by running tests on a non-production environment or by running tests at times when disruption will be minimized.

A common drawback of email software packages that provide native encryption of messages is that the encryption cannot interoperate across product domains. This means that emails sent from one product cannot be read by another product, as the encryption keys used are not compatible. This can be a problem when sending emails to people who use different software packages, as the encrypted emails cannot be read.
