Speed and Efficiency: excels in encrypting large data volumes due to its faster processing compared to other methods like asymmetric encryption Low Resource Consumption: ideal for devices with limited computing power, like mobile phones or embedded systems Shared Key Management: requires secure sharing of a single secret key between authorized parties, which might be challenging in complex scenarios Suitable Files/Data:- Large data sets, Streaming data & Disk encryption Strengths and Security:- Confidentiality, Integrity & Algorithmic security Limitations:- Key Management & Non-Repudiation Context matters: Consider factors like data sensitivity, resource constraints, and access control needs when choosing an encryption method.

Pros : 1. This makes symmetric encryption ideal for scenarios where quick processing is required. 2. Their straightforward nature simplifies the encryption process, making it accessible for a wide range of applications. 3. Since the key needs to be shared only with the intended recipients, it is a practical solution for scenarios where data sharing is limited. Cons : 1. Key securely distributing the encryption key to all authorized parties 2. alone does not provide built-in mechanisms for data integrity and authentication. 3. distributing the key to numerous recipients becomes impractical and poses a security risk.

Symmetric Encryption is faster and more suitable for large volumes of data at rest. It requires only a single key and easier to handle; but managing and sharing becomes a problem. It only provides confidentiality. So based on these aspects, symmetric encryption should be used accordingly.

Symmetric encryption is a type of encryption that uses the same key for both encrypting and decrypting data. The key is typically a random sequence of bits or characters and should be kept secret and shared only with the intended recipients. Symmetric encryption is fast and efficient and can handle large amounts of data. Some of the most common symmetric encryption algorithms are AES, DES, and Blowfish. Symmetric encryption is suitable for data at rest that does not need to be shared with many parties, such as personal files, local databases, or internal network communications.

Public-key Infrastructure: Public key is freely shared, while the private key stays secret, enabling secure communication without pre-shared secrets Digital Signatures: Provides non-repudiation & data integrity verification Key Exchange: Securely establishes shared secret keys for symmetric encryption in complex scenarios Suitable Files/Data: Small, sensitive data, Key exchange. Strengths & Security: Confidentiality, Non-repudiation, Mathematical Complexity Limitations: Performance & Key Management Remember: Consider context: Use asymmetric encryption when secure communication, non-repudiation or digital signatures are crucial Combine techniques: Pair it with symmetric encryption for bulk data encryption or efficient decryption

Thinking about using asymmetric encryption for your stored data? Here’s what to expect: 𝐏̲𝐫̲𝐨̲𝐬̲:̲ 𝐏𝐞𝐚𝐜𝐞 𝐨𝐟 𝐦𝐢𝐧𝐝: Two keys mean it's tougher for intruders to access your info. 𝐓𝐫𝐮𝐬𝐭: You can be sure your data stays as it was when you saved it. 𝐀𝐜𝐜𝐨𝐮𝐧𝐭𝐚𝐛𝐢𝐥𝐢𝐭𝐲: It's clear who sent what, cutting down on disputes. 𝐂̲𝐨̲𝐧̲𝐬̲:̲ 𝐏𝐚𝐭𝐢𝐞𝐧𝐜𝐞 𝐧𝐞𝐞𝐝𝐞𝐝: It's not as quick as other methods, so large files take time. 𝐊𝐞𝐲 𝐜𝐚𝐫𝐞: Lose the private key, and you could lose access to your data. 𝐒𝐞𝐭𝐮𝐩 𝐬𝐰𝐞𝐚𝐭: It's a bit more complex than just setting a password. Great for sensitive info, but consider if the extra steps fit your daily needs. #DataAtRest #AsymmetricEncryption #TechTips

There are two keys, a public key and a private key, one to encrypt and the other one to decrypt. The encryption process is slow and resource utilization is high. It is used to transfer small amounts of data. It provides confidentiality, authenticity, and non-repudiation. The length of key used is 2048 or higher. They can be used for key exchange mainly.

Asymmetric encryption is a type of encryption that uses a pair of keys, one public and one private, to encrypt and decrypt data. The public key can be shared with anyone and is used to encrypt data. The private key is kept secret by the owner and is used to decrypt data. Asymmetric encryption is more secure and flexible than symmetric encryption, but it is also slower and more complex. Some of the most common asymmetric encryption algorithms are RSA, ECC, and ElGamal. Asymmetric encryption is suitable for data at rest that needs to be shared with many parties, such as emails, digital signatures, or certificates.

"At Rest" Defense: Even if your device is powered off or stolen, your data remains shielded by the encryption. This adds a layer of security crucial in cases of physical theft or loss. Ideal Files & Data: Sensitive Personal Information, Confidential Business Data, Intellectual Property & Compliance Requirement. Performance: Full disk encryption may slightly impact system speed, particularly on older hardware. Modern systems generally handle this well Key Management: Choosing a secure password or utilizing hardware-based security solutions (like a Trusted Platform Module) is vital to protect your encryption key In summary, disk encryption offers a superior security solution for any sensitive data needing strong, "always-on" protection

Disk encryption is a technology that encrypts an entire disk or a partition of a disk, rather than individual files or folders. Disk encryption can provide a high level of security for data at rest, as it prevents unauthorized access to the data even if the disk is removed or stolen. Disk encryption can be implemented at the hardware level or the software level. Hardware-based disk encryption uses a dedicated chip or circuit to perform encryption and decryption, and requires a password or biometric authentication to unlock the disk. Software-based disk encryption uses a program or a feature of the operating system to perform encryption and decryption, and requires a password or a key file to unlock the disk.

Here are some common methods used to encrypt data in the cloud: -Server-Side Encryption: occurs after the cloud receives your data, but before the data is written to disk and stored -Client-Side Encryption: encrypted on the user's device before transferred to cloud -In-Transit Encryption: encrypting data while it is being transferred using TLS -At-Rest Encryption: encrypting data stored 'at rest' -Zero-Knowledge Encryption: only the user has the encryption keys, ensuring that no one else, not even the service provider, can decrypt the data -Customer-Managed Encryption Keys: User can create and manage their own encryption keys through Cloud Service -Third-Party Encryption Tools: encrypt your files before you upload them to the cloud

In the digital era, securing data stored in the cloud is crucial. Cloud encryption, transforming data into a format readable only with a key, is vital for protection. Use strong encryption methods like AES-256 for data at rest. Opt for cloud services that offer built-in encryption and manage your keys securely, keeping them separate from the data. Encrypt data before uploading for an extra security layer. Remember, while cloud platforms secure the infrastructure, data protection is often up to you. Understand your cloud service's security features and adopt best practices to ensure your information remains safe. #CloudSecurity #DataEncryption #DigitalSafety

Cloud encryption is a technology that encrypts data before it is stored on a cloud service provider's servers, or while it is in transit between the user and the cloud. Cloud encryption can protect data at rest against unauthorized access by the cloud service provider or third parties, as well as against interception or manipulation during transit. Cloud encryption can be performed by the user or by the cloud service provider. User-side cloud encryption uses a program or a plug-in to encrypt data with a key controlled by the user before uploading it to the cloud. Provider-side cloud encryption uses a service or a feature to encrypt data with a key controlled by the provider after uploading it to the cloud.

Data masking is essential for securing sensitive data at rest. Start by identifying which data needs protection, like personal or financial information. Use static masking for data stored for non-real-time use and dynamic masking for live environments to maintain usability while ensuring privacy. Update masking protocols regularly to align with new regulations and organizational changes. Combine data masking with encryption for robust security. Regular audits are crucial to confirm compliance and effectiveness. Implementing these strategies enhances data safety without losing functionality.#DataSecurity #DataMasking #RiskManagement

Data handling techniques should be used to prevent personal identity from being revealed by deleting or masking Personal Data attributes. Some of the scenarios where this should be done are: Used in any non-production environment for any purpose Shared with any external party unless it’s to perform a service through a contractual arrangement Used for a secondary purpose that would not otherwise be permitted if the data was identifiable Sensitive data can be handled by the following methods: AGGREGATION ANONYMIZATION ENCRYPTION FILTRATION GENERALIZATION HASHING MINIMIZATION MASKING / REDACT / SUPRESS SUBSTITUTION / SYNTHETIC DATA GENERATION TOKENIZATION VARIANCE

We can’t say one technology is better than another. Different technology solves different purposes. In many cases we choose combination of more than one technology. So when we design overall data at rest strategy of the organisation then all above mentioned technologies will be used in combination depending on the use case and underlying service where it is applied.

Data encryption isn’t difficult. Key management is difficult. Data Restoration is difficult. Building a process to provide a remote Executive on another continent with a Bitlocker key at 2:30am on a Sunday morning over a holiday weekend is difficult. Understand your requirements, build your processes, contingency plan worst-case scenarios, then EXERCISE those plans regularly.

The best encryption is the one that works. There are different applications, processing speed, strength of protection, compatibility, and ease of implementation to consider. Use guidance from organization that specialize in the information, such as the NSA. Typically, these types of organizations test and approve different types of encryption for the use case and recommend strengths. Use these as a baseline to make these decisions for your situation. It's a bad idea to create your own solution as encryption algorithms are very complex and rigorously tested, well beyond what a typical organization can provide. Lastly, be aware of quantum computing. Quantum encryption has started, and will evolve quickly when quantum computing is mainstream.

A while back I was assessing a few block-encryption appliance solutions for NAS/SAN storage in the glass house. The customers weren't really clear on what loss scenario they were trying to prevent. I hypothesized that the solutions seemed to mainly address physical theft of the media, which at the time would've likely involved use of a wrecking ball and a forklift. They wanted the solution to prevent access to all but authorized users (i.e., those who had credentials and authorization defined). While this may have technically satisfied PCI requirements, it wouldn't have moved the bar for data theft - steal the credentials, steal the data. Transparency of a cryptographic solution is usually inversely proportional to its effectiveness.

In certain cases, not all data needs to be encrypted during storage (data at rest). Identify the data sets/fields considered business-critical or confidential, and encrypt only those, rather than encrypting the entire database. This approach improves efficiency when retrieving data, as encrypting the entire database could be time-consuming and slower when data retrieval is necessary.

The choice of encryption method depends on factors such as security requirements, system compatibility, and performance considerations. Here are some widely adopted encryption technologies for securing data at rest: 1. AES (Advanced Encryption Standard 2. TDE (Transparent Data Encryption) 3. BitLocker 4. FileVault: For MAC OS 5. LUKS (Linux Unified Key Setup) 6. Self-Encrypting Drives (SED) 7. Vormetric Data Security Platform 8. dm-crypt 9. Hardware Security Modules (HSM) 10. Hybrid Cloud Encryption Solutions When implementing data-at-rest encryption, it's essential to manage encryption keys securely, monitor and audit access, and ensure proper key rotation practices.
