What Is Data Encryption?
Data encryption is safeguarding sensitive information by encoding it with encrypted information (called ciphertext ), which can only be decoded with a unique key generated at or before encryption is performed, making sure only authorized individuals have access or use of keys generated at encryption time or before.
Typically used during storage or transmission and authentication services to ensure access or usage rights remain exclusively within authorized hands.
Why Is Data Encryption Necessary?
Promotes Data Integrity
Data encryption helps ensure data authenticity by guarding against alteration or manipulation from third parties while at the same time helping prevent corruption that often arises when data travels from one system to the next - adding an extra level of protection against unintended data corruption.
Supports Compliance
Many industries impose stringent regulations regarding protecting and handling sensitive information, with healthcare falling under HIPAA and financial services adhering to PCI-DSS as requirements for security compliance.
Businesses can meet regulatory compliance by adopting data encryption solutions; doing so could save them from incurring potential fines or penalties for noncompliance.
Protects Data In Transit
Data transferred between devices or systems can be particularly susceptible to unauthorized access. Encryption protects this sensitive data during transit by only allowing parties with the relevant decryption key to access it.
With more employees accessing company information from mobile devices than ever, risks associated with data breaches have escalated exponentially; encryption protects sensitive information on mobile devices and that sent between these devices and company networks.
Protect Data In Cloud Storage
Cloud storage offers many advantages for businesses, including increased accessibility and reduced infrastructure costs.
Still, it can pose unique security issues for users. Companies storing data with cloud services must protect it while at rest or stored on servers - adding extra protection with data encryption can ensure unauthorized parties don't gain access to encrypted information without first possessing the key required for decryption.
Securing Remote Work
Remote work has become more widespread. Data breaches and security incidents related to employees who work from home or other remote locations have significantly increased as more employees telecommute for work purposes.
When employees access sensitive data remotely, key Encryption can offer the best protection possible because it guarantees that it will stay secure even if their devices or connections are hacked.key Encryption can provide the perfect protection for sensitive information accessed remotely by employees - it ensures it remains protected even if their devices or connections become compromised.key Encryption can provide the perfect protection for sensitive information accessed remotely by employees - it ensures it remains protected even if their devices or connections become compromised.
Protects Intellectual Property
Intellectual property, such as trade secrets and proprietary algorithms or product designs, is crucial to an enterprise.
Protecting this valuable information helps preserve a competitive edge while preventing corporate espionage; data encryption provides another layer of defense by making certain that even if untrusted parties gain access to this sensitive data, they cannot decrypt its contents and use them against you.

What Is The Encryption Process?
Complex mathematical algorithms combined with digital keys are employed for key encryption to secure data. A cipher algorithm and key are utilized for data encoding before being decoded back once transmitted to their destination recipient.
Data encryption success relies on its keys; they act like physical locks to only open encrypted information with their correct coded keys.
You can create them manually or use encryption security software that scrambles your data before making its encryption key.
There are two methods available to generate encryption keys.
- Bit sequence: Keyspace refers to the total number of possible key combinations specified as logarithmically increasing units; as more keyspace becomes available, more robust encryption against brute-force attacks becomes.
- Password-Based Key Derivation 2 (PBKDF2): Creates keys by employing passwords. Pseudorandom strings are added to each password and translated into bit sequences of any desired length using a cryptographic hash function.
What Is The Purpose Of Encrypting Information?
Modern encryption protects more than sensitive data.
- Protects privacy: Encryption can help ensure privacy by safeguarding the information on our computers, like tax forms, banking records or application forms - whether this data resides directly on or is viewed through a web browser.
- Blackmail and identity theft: Hackers try to blackmail and steal data to demand ransom from its owners. Attackers then threaten to release sensitive details if you do not comply, possibly leading them to use stolen identities to commit identity fraud. However, by using encryption for personal data security purposes, these hackers won't be capable of decrypting it, so holding onto your information won't be worthwhile as ransom demands.
- Secure file sharing: 2021 saw an average cost for data breaches at organizations with four or more remote employees totalling $5 Million, as cybercriminals easily intercept data sent over unprotected networks by remote employees. Encryption ensures no unauthorized person or software can gain access to shared files.
- Protects stolen and lost devices smartphones, Laptops and Tablets are easily lost or misplaced: hackers have access to them with relative ease, giving them access to data not adequately protected by encryption on lost or stolen devices - hackers cannot gain entry without first knowing an encryption key (password).
- Encryption ensures compliance: Encryption helps businesses meet regulatory standards and requirements, such as those in your industry's regulations, to maintain compliance. Encryption may even be mandatory to meet such rules. For instance, the General Data Protection Regulation and California Consumer Privacy Act mandate businesses to encrypt customer personal data stored and transmitted across public networks.
The Difference Between Symmetrical And Asymmetric Encryption
The type of encryption depends on the intended use and who will access the data.
Private Encryption Key (Symmetric Encryption)
Symmetric encryption utilizes a private key for encryption and decryption, making the method faster than its asymmetric counterparts and ideal for individuals or closed systems.
When applied openly, such as in networks with multiple users or with many users sharing one password or account, however, the transmission of keys creates a potential theft risk; AES cryptography is one of the more famous examples of symmetric cryptography.
Asymmetric Encryption (Public Encryption Key)
Asymmetric encryption uses mathematically linked pairs of keys that must only be used together when decrypting data, so asymmetric encryption can only be used by multiple people on open networks like the Internet due to public key sharing; ElGamal is one such asymmetric type.

Types Of Data Encryption
Data Encryption Algorithms Examples
The most common data encryption algorithms are:
- Triple DES (DES or 3DES): 3DES runs the old standard DES three times to create an extended key length and can use one, two or all three keys as possible for increased security. As a block cipher, it is vulnerable to attacks like block collision.
- RSA: was among the original public key algorithms, employing an asymmetric, one-way encryption method with long key length for increased popularity on the Internet. Used widely across multiple security protocols like SSH, OpenPGP and SSL/TLS protocols and browsers establishing secure connections over insecure networks, this long key length has made RSA popular and widespread usage on this virtual space.
- Twofish: VeraCrypt and KeePass all include VeraCrypt as one of their fastest algorithms with sizes 128, 196 and 256 bits that utilize an intricate essential structure that ensures maximum security. Plus, free and open-source software programs such as VeraCrypt use it!
- Elliptic Curve Cryptography: ECC was designed to improve RSA to offer more excellent protection with shorter key lengths and can also be used within SSL/TLS protocols. It uses an asymmetrical method called ECC for encryption purposes.
- Advanced Encryption Standard: AES encryption was adopted as the US Government standard by law and implemented with ease with both hardware and software solutions. Utilizing block ciphers and symmetric key algorithms, AES comes in sizes of 128, 192 and 256 bits with increasing rounds of encryption depending on its size - designed to be easily implemented for every task at hand.
- Blowfish: is an asymmetrical cipher with key length options ranging from 32 bits to 448. Performance depends upon which key length is selected; Blowfish utilizes block ciphering encryption technology which divides data into blocks with 64-bit sizes for encryption purposes.
- Format-Preserving Encryption: This encryption algorithm offers content anonymization by encrypting information while keeping its format unchanged; for instance, if a customer ID contains two letters and 10 digits, then when encrypted, the version will retain those characters and numbers while altering some characters to safeguard data privacy.
Data Encryption Standards
Here are two standards you should watch for regarding data encryption algorithms used in organizations.
Nist Federal Information Processing Standard (Fips) 140-2
FIPS was developed according to the Federal Information Security Management Act to meet government agency encryption needs.
Still, many private businesses also employ FIPS encryption protocols to protect sensitive data.
Standard Criteria For Information Technology Security Evaluation
CC stands for Cooperative Computing (CC), not encryption standards; instead, it is an international collection of guidelines evaluating product security claims.
Although encryption software was initially excluded from CC standards for projects, encryption has increasingly become part of project-specific security standards over time.
CC guidelines aim to ensure security products can be evaluated relatively by an impartial third-party supervisor without regard to the vendor.
Effects submitted voluntarily for review can be assessed on whole or individual functionality and tested up to seven levels compared with applicable standards based on product type.
Data At Rest Vs. Data In Transit: Encryption
Data must be protected and covered effectively, whether in transit between users or stored on servers. Depending on its state, its protection can vary accordingly.
Data Encryption On Transit
Any time information goes between devices, whether it's across a private network, the Internet, or from a laptop to a thumb drive, it's considered to be "data in transit.".
Transfer methods, particularly ones that involve decrypting before transfer, can place information at risk; end-to-end encryption protects privacy even if data is intercepted during transport.
Data Encryption In Rest
Data stored on devices at rest is inactive - meaning no active use or transfer occurs. Due to security features that restrict access, stored information can be less vulnerable than data in transit; however, theft could still pose an increased threat as valuable items become more straightforward targets.
By lengthening access times and granting us more security, encrypting data at rest lowers the risks of data theft due to lost or stolen devices, unplanned password sharing, or unintentional permission grants.
time to detect data loss, ransomware infections, remote erased files or altered credentials.
Can Encrypted Data Be Hacked?
Yes, encrypted data can be compromised via various techniques available to attackers. There exist multiple means by which attackers could compromise encryption systems that protect sensitive information.
- Malware in endpoint devices: Numerous endpoint devices come equipped with encryption mechanisms such as full disk encryption. Malware could use these encryption methods against them and decrypt data on them. This opens them up for attack from cyber criminals who wish to compromise endpoint devices and gain entry.
- Brute Force Attacks: An attacker will often try different keys at random to crack encryption, with crucial size having an immediate bearing on their chances of success; most encryption standards require 256-bit keys, while some systems employ weak ciphers that may be susceptible to brute-force attacks.
- Cryptanalysis: Cyber attack involves exploiting weaknesses within a cipher to access sensitive data.
- Side channel attacks: Searching for vulnerabilities within a system's design that allow users to decrypt or prevent information from being encrypted without breaking its cipher is known as pen testing. Cracking requires breaking its cipher completely and cracking its encryption keys directly.
- Social Engineering Attacks: Employing social engineering techniques such as phishing to persuade privileged users to provide access keys is the quickest and most straightforward way to gain entry to encrypted data.
- Insider Threats: Data encryption can come under threat when someone with access to its database turns against an organization and abuses his position to steal sensitive information. Insider threats may also arise due to users failing to abide by security policies.
Encryption remains an effective and robust security measure despite these risks. However, its success must still be evaluated as part of an organization's defensive posture, not its sole defense mechanism.
What Is Cloud-Based Encryption (CBE)?
Cloud service providers typically offer encryption as part of their offerings or independently. You must research their offerings before selecting a cloud service provider and purchasing cloud-based security.
- How strong is the encryption? Does it meet the requirements of the organization?
- There are different models, including client-managed and fully-managed encryption keys.
- How to implement end-to-end encryption to encrypt data from the cloud to the end user and back.
Cloud encryption is an integral component of any cloud security strategy, yet organizations should remain mindful of several critical points:
- Users often view Cloud encryption as complicated, mainly when it involves end-to-end encryption.
- Cloud encryption can be complicated for systems that run on-premises or endpoint devices.
- It is essential to monitor cloud encryption, as it is a computationally intensive process. It can result in high cloud prices depending on the pricing model.
- If keys are not managed properly, they can be lost, rendering the data useless. Encryption will also offer no benefit if the keys are not protected.
Data Encryption Solutions: Key Features
Data encryption solutions enable organizations to implement widespread encryption.
They feature advanced algorithms and management Encryption tools designed to deploy encryption quickly across an enterprise; deploy password management tools; set access policy; monitor implementation progress -- everything needed for successful enterprise encryption implementation!
Data encryption solutions should be straightforward to implement or, even better, transparent to encrypt sensitive information without human interference.
They must also be scalable enough to handle expanding volumes and quick enough not to hinder employee productivity.
These are the features to look out for when looking to encrypt data:
- Substantial encryption standard: The industry standard today for encryption is Advanced Encryption Standard with a key of 256 bits.
- Encryption at Rest: Data can be stored on file servers or databases, employee workstations and in the cloud. It is essential that the solution can reach all of these locations and encrypt sensitive information.
- Encryption in transit: The answer should be capable of encrypting data transmissions with transport layer security (TLS), a protocol encrypted that ensures the authenticity of messages and prevents listening.
- Granular Controls: The solution should allow for selective encryption of sensitive data within the organization without data encryption. It can, for example, allow encryption of specific folders, programs, storage devices or file types.
- Key Management: is an integral part of encryption management. When access to the data is denied, the solution should be able to swiftly produce encryption keys, distribute them to the data owners, backup those keys, and then delete them.
- Enforcement of policies: solutions should allow organizations to define and enforce encryption policies automatically. For instance, actions like saving a document to removable storage or emailing it can be blocked until an employee encrypts that file.
- Always on encryption: With many systems, sensitive files' encryption can continue to function even after being copied or changed.
Data Encryption Trends Types
Here are some trends that will likely drive the development and growth of data encryption.
Bring Your Encryption
BYOE (Bring Your Key or BYOK) is a cloud computing security model which enables customers to utilize encryption keys managed with their software, often called BYOK or Bring Your Key (BYOE), with applications hosted in the cloud.
Customers use virtualized versions of their encryption software in combination with cloud applications.
Encryption As A Service (EAAS)
EaaS (Encryption as a Service) is a subscription-based model where cloud providers charge customers on a usage basis.
This service addresses compliance concerns while giving customers control of their encryption to protect data within multi-tenant environments. EaaS services may offer full disk encryption (FDE), database or file encryption as part of this package.
Cloud Storage Encryption
Cloud storage providers use encryption algorithms for all data stored online, similar to what would be done in-house; however, critical distinctions may exist.
Cloud customers must take time and care to understand the policies and procedures of their provider regarding encryption and key management to ensure their encrypted data remains as safe as possible.
End-To-End Encryption (E2EE).
E2EE ensures that an attacker intercepting a communication channel cannot see any data being transferred. However, this cannot be guaranteed with Transport Layer Security (TLS), an encrypted channel between clients and servers, because attackers could still gain access to content before or after both clients decrypt it and before or after the server does decrypt.
Field-Level Encryption
Field-level encryption enables you to encrypt specific fields, like credit card numbers, Social Security numbers, account numbers or health information.
Sequential Link Encryption
This method encrypts data before leaving its host, decrypts it on each subsequent network connection (relay or host), and then re-encrypted before sending it to another link; each may use different algorithms or keys for data encrypting.
This process continues until all recipients of data receive it.
Network-Level Encryption
This method provides cryptographic services at the network forwarding layer (level 3 of the OSI model), located above the data-link layer but below the application layer.
Internet Protocol Security (IPsec) is one solution that achieves level 3 encryption by creating an environment of secure communication in IP networks using IETF standards.

Benefits Of Encryption
Protects Data Across Devices
Data is constantly in motion, whether conversations between friends or financial transactions. Encryption with additional security features like authentication can ensure data stays protected while it moves along its journey.
Ensures Data Integrity
Encryption protects data against theft or alteration from malicious actors who could misuse it to commit fraud, extort money from people they don't like, or falsify essential documents.
Protects Digital Transformations
Cloud storage has quickly become popular with individuals and organizations alike. Encryption plays an integral part in protecting data during its journey to rest on servers at rest, processing by workloads in and processing through Google Cloud Platform servers.
We offer various levels of encryption and essential management encryption services from Google.
Comply With Compliance Requirements.
Strong encryption is required by many data privacy and security laws, such as for healthcare transactions involving credit and debit cards (Payment Card Industry Data Security Standard PCI DSS, General Data Protection Regulations GDPR and Fair Credit Practices Act FCPA), retail transaction information with Fair Credit Practices Act FCPA etc.
Encryption Has Its Disadvantages.
Ransomware
Encryption can protect the information, but malicious actors have used encryption as a weapon against organizations by holding their data hostage until paying a ransom payment.
Key Management
Encryption becomes less effective if the cryptographic key that encrypts data is compromised. Attackers frequently target organizations looking for their encryption keys; lost encryption keys could result in their being locked out entirely from critical data.
Organizations often employ key-management systems to manage and secure these keys.
Quantum Computing
Quantum computing poses a substantial threat to modern encryption methods. Once it becomes mainstream, quantum computers will be capable of processing massive data volumes much more rapidly than current computers; as a result, quantum encryption could potentially crack existing encryption.
Quantum encryption could soon become standard among organizations looking for better protection of their information assets and passwords against future quantum attacks from quantum computers. However, quantum computers haven't cracked modern encryption standards. NIST recently unveiled four "quantum-resistant" algorithms which protect from these quantum attacks.
