Resilience in a contested cyber environment is like a castle’s walls standing strong against a siege. Its cloud networks are the moat that protects it from attack, while its cybersecurity measures are the drawbridge and portcullis that keep out intruders.
Resilience is the ability to stay online and continue business operations despite cyber-attacks, and it requires protection of data at rest, in transit, and in use. Businesses should prioritize security of data that is defined by regulation, intellectual property, and financial data, as well as anything that is essential to survival and sustainability. The cloud provider promises availability of resources in an SLA, and backups of critical data should be spread across multiple vendors. Visibility into the cloud network can be achieved with cloud access service brokers, and incident response tests should be conducted periodically to assess preparedness.
