The uses of encryption and the benefits of securing communications by hash functions
Provide Additional Considerations for the CISO
You have satisfactorily identified key management gaps. Incorporate these additional objectives of an enterprise key management system as you compile information for the CISO.
1. Explain the uses of encryption and the benefits of securing communications by hash functions and other types of encryption. When discussing encryption, be sure to evaluate and assess whether or not to incorporate file encryption, full disc encryption, and partition encryption. Discuss the benefits of using triple DES or other encryption technologies. To complete this task, review the following resources:
2. Describe the use and purpose of hashes and digital signatures in providing message authentication and integrity. Review these resources on authentication to further your understanding. Focus on resources pertaining to message authentication.
3. Review the resources related to cryptanalysis. Explain the use of cryptography and cryptanalysis in data confidentiality. Cryptanalysts are a very technical and specialized workforce. Your organization already has a workforce of security engineers (SEs). Cryptanalysts could be added to support part of the operation and maintenance functions of the enterprise key management system. Conduct research on the need, cost, and benefits of adding cryptanalysts to the organization’s workforce. Determine if it will be more effective to develop the SEs to perform these tasks. Discuss alternative ways for obtaining cryptanalysis if the organization chooses not to maintain this new skilled community in-house.
4. Research and explain the concepts and practices commonly used for data confidentiality: the private and public key
Sample Solution
Encryption: Encryption is the process of converting data into a form that is unreadable by unauthorized parties. It is a critical security measure that can be used to protect sensitive data, such as passwords, credit card numbers, and medical records. There are many different types of encryption, including file encryption, full disc encryption, and partition encryption.Full Answer Section
- Encryption: Encryption is the process of converting data into a form that is unreadable by unauthorized parties. It is a critical security measure that can be used to protect sensitive data, such as passwords, credit card numbers, and medical records. There are many different types of encryption, including file encryption, full disc encryption, and partition encryption.
- File encryption: File encryption is the process of encrypting individual files. This is a good option for protecting sensitive files that are not stored on a central server.
- Full disc encryption: Full disc encryption is the process of encrypting the entire hard drive of a computer. This is a good option for protecting all of the data on a computer, including the operating system, applications, and personal files.
- Partition encryption: Partition encryption is the process of encrypting a specific partition on a hard drive. This is a good option for protecting data that is stored on a shared drive or a removable media device.
- Hash functions: Hash functions are a type of encryption that is used to create a unique identifier for a piece of data. This identifier, called a hash, cannot be reversed to reveal the original data. Hash functions are often used to verify the integrity of data, as well as to create digital signatures.
- Triple DES: Triple DES is a type of encryption that uses three different keys to encrypt data. This makes it much more secure than single DES encryption.
- Data security: Encryption can help to protect sensitive data from unauthorized access.
- Data integrity: Hash functions can help to verify the integrity of data, ensuring that it has not been tampered with.
- Digital signatures: Digital signatures can be used to verify the authenticity of a message or document.
- The sensitivity of the data: The more sensitive the data, the stronger the encryption method should be.
- The type of data: Some types of data, such as images and videos, are more difficult to encrypt than other types of data, such as text.
- The performance requirements: Some encryption methods can have a significant impact on performance.
