Organizations use a wide variety of encryption technologies for various purposes

Question

Organizations use a wide variety of encryption technologies for various purposes. A key aspect of security is to apply the correct and necessary levels of encryption and hashing. The type of encryption and hashing needed varies according to the type of organization: government, military, healthcare, academic, business, financial, etc. For this discussion, address at least two of the following questions. Why is cryptology important in information security? What implications would follow from not using cryptological technologies? Why might vendors propose proprietary encryption methods? Why is this recommendation suspect and what are possible or likely downside risks to adopting a proprietary encryption technology? What are the benefits of using encryption? What are the negatives or costs associated with using encryption?

Explanation / Answer

All efforts to protect systems and networks attempt to achieve three outcomes:

data availability, integrity, and confidentiality.

And as we have also seen, no infrastructure security controls are 100% effective.

In a layered security model, it is often necessary to implement one final prevention control wrapped around sensitive information encryption.

Encryption is not a security panacea.

It will not solve all your data-centric security issues.

Rather, it is simply one control among many.

asymmetric cryptology techniques is used .

Benefits

Separation: Data encryption allows the data to remain separate from the device security where it is stored.

No Data Breaches

Encryption Is On The Data: In encryption is on the data itself, the data is secure regardless of how it was transmitted.

Negatives:

Maintenance cost is high.

Compatability
