1 Encryption Methods and Key Types
When designing a key management system, the first step is to decide what encryption methods and key types to use for the data. Symmetric encryption uses the same key for both encryption and decryption, making it faster and simpler than asymmetric encryption. However, a secure way to distribute and store the key must be established. Asymmetric encryption uses a pair of keys, one public and one private, for encryption and decryption. This is more secure and flexible but more complex and slower. Hybrid encryption combines symmetric and asymmetric encryption, offering advantages of both methods while reducing their drawbacks. Factors such as the type and size of the data, the level of security required, the performance and scalability of the system, and the compatibility and interoperability of devices and applications should be taken into account when deciding on the encryption methods and key types.

(Two-way encryption): - Symmetric Encryption: Same key is used for both encryption and decryption and more efficient for bulk encryption ex: AES (Advanced Encryption Standard, DES (Data Encryption Standard, 3DES (Triple Data Encryption Standard)- Asymmetric Encryption (Public-Key Encryption): A pair of keys is used: a public key for encryption and a private key for decryption (or versa) useful for exchange keys ex: RSA (Rivest-Shamir-Adleman, Elliptic Curve Cryptography (ECC)(one-way encryption): - Hashing: data is converted into a fixed-length string of characters called a hash value. It's used for data integrity verification and password storage.

2 Key Storage and Rotation
The next step in designing a key management system is to determine how and where you will store and rotate your keys. Key storage refers to the physical or logical location and format of the keys, as well as the access control and protection mechanisms applied to them. Key rotation involves changing or replacing keys periodically or after a certain event, such as a breach, a compromise, or a policy update. When considering key storage and rotation, you must take into account the storage location (on-premise, cloud, or hybrid), format (plain text, encrypted, or wrapped), protection (encryption, authentication, authorization, logging, auditing, backup, recovery, destruction), and rotation frequency (daily, weekly, monthly, quarterly, yearly). On-premise storage gives you more control over your keys but also more responsibility for their maintenance and security. Cloud storage offers more convenience and scalability but also more dependency on the cloud provider. Hybrid storage balances the benefits and challenges of both options. Plain text keys are easy to use but also easy to steal and misuse. Encrypted keys require another key to decrypt them. Wrapped keys are encrypted with a master key stored separately. Key rotation increases security by reducing exposure and lifespan of your keys; however it also increases complexity due to coordination among parties involved and more testing/validation of new keys.

- 🔐 Determine key storage location (on-premise, cloud, hybrid) based on control, convenience, and security requirements.- 🔒 Use encrypted or wrapped keys for enhanced protection, with plain text keys only as a last resort.- 🛡️ Implement strong access control measures, including encryption, authentication, authorization, logging, and auditing.- 🔄 Establish a key rotation policy with a defined frequency (daily, weekly, monthly, etc.) to reduce exposure and enhance security.- 📦 Ensure robust backup, recovery, and key destruction processes to maintain integrity and availability of keys.

3 Key Auditing and Monitoring
The final step in designing a key management system is to establish how and when you will audit and monitor your keys. Key auditing is the process of verifying the integrity, security, and compliance of your keys, as well as identifying and resolving any issues or anomalies. Key monitoring involves tracking and measuring the performance, availability, and usage of your keys, as well as detecting and responding to any threats or incidents. The scope of key auditing depends on the complexity and risk of your system, the type and purpose of your keys, and the regulatory and compliance standards. You can audit your keys at different intervals, such as on-demand, periodically, or continuously. Different tools and methods can be used for auditing your keys, such as manual inspection, automated scanning, penetration testing, vulnerability assessment, compliance audit, incident response, forensic analysis, and remediation. When it comes to key monitoring metrics, you can measure availability, performance, usage, quality, security, and cost.
