Drive Encryption For Client And Tax Data – Security Six

Drive encryption is a critical component of cybersecurity that helps protect sensitive data stored on various devices from unauthorized access. With the growing threat of cyberattacks, the need for encryption has become more prevalent to prevent sensitive data from being accessed by unauthorized individuals.
Encryption is a complex process that involves converting data on a computer into a code that can only be read by someone with the correct key or password. In the context of drive encryption, the data stored on a hard drive, laptop, desktop, server, or any other removable media is encrypted to prevent unauthorized access. The Security Six and IRS Publication 4557 require the use of encryption to protect client and tax information stored on any drive.
In the absence of encryption, attackers can easily gain access to sensitive information stored on a device if it is lost or stolen. Encryption is an important tool that provides an added layer of security to protect data from unauthorized users. It is not foolproof, but it is a crucial step in ensuring the protection of sensitive data.

The Evolution Of Encryption In The Digital Age

With the advancements in technology, encryption has become an essential tool for protecting sensitive information in the digital age. Encryption has come a long way since the days of the scytale and Caesar Cipher. In the early days of computing, encryption was primarily used by governments and military organizations to protect their communication channels. However, with the rise of the internet and the proliferation of digital devices, encryption has become ubiquitous, and its importance has only grown.
One of the earliest encryption methods used in computing was the Data Encryption Standard (DES), which was developed by IBM in the 1970s. This was a symmetric key encryption system that used a 56-bit key to encrypt and decrypt data. While DES was widely used for many years, its relatively short key length made it vulnerable to brute force attacks.
In response to the weaknesses of DES, the Advanced Encryption Standard (AES) was developed in the late 1990s. AES is a symmetric key encryption system that uses a 128, 192, or 256-bit key to encrypt and decrypt data. AES has become the standard encryption algorithm used by the US government and is widely used in commercial applications.
Another important development in encryption has been the emergence of public key cryptography. In the 1970s, Whitfield Diffie and Martin Hellman introduced the concept of public key cryptography, which uses a pair of keys (public and private) to encrypt and decrypt data. Public key cryptography has many advantages over symmetric key cryptography, including improved security, scalability, and ease of use.
Today, encryption is used for a wide range of applications, from securing online banking transactions to protecting personal information stored on smartphones and other devices. In addition to AES and public key cryptography, there are many other encryption methods available, including elliptic curve cryptography and homomorphic encryption.
Despite the importance of encryption in protecting sensitive information, there are still challenges to its implementation. For example, some governments have called for encryption backdoors, which would allow them to bypass encryption to access data in certain circumstances. However, implementing backdoors would undermine the security of encryption and could lead to the exposure of sensitive information.
Encryption has a long and fascinating history, and its importance has only grown in the digital age. From the scytale to AES and public key cryptography, encryption has evolved to become an essential tool for protecting sensitive information. As we continue to rely on digital devices for more aspects of our lives, encryption will play an increasingly important role in ensuring the security and privacy of our data.

What Is Encryption?

Encryption is a vital tool in the field of cybersecurity as it helps to protect sensitive data from unauthorized access. It involves the use of complex algorithms to convert plain text into scrambled text or ciphertext, which cannot be read without a decryption key. This ensures that data can be accessed only by those who are authorized to do so.
There are two main types of encryption: symmetric and asymmetric. Symmetric encryption involves the use of a single key to both encrypt and decrypt the data. This method is simpler and faster, but it requires the key to be kept secret. Asymmetric encryption, on the other hand, uses two keys: a public key for encryption and a private key for decryption. This method is more secure but can be more time-consuming.
Encryption is a widely used method for protecting data in various industries, such as finance, healthcare, and government. It can be used to secure data at rest, which is data that is stored on a device or server, as well as data in transit, which is data that is being transmitted over a network.
It is important to note that encryption is not foolproof and can be vulnerable to attacks if not implemented correctly. Therefore, it is crucial to use strong encryption methods and keep the keys secure. Additionally, regular updates and maintenance are necessary to ensure that encryption technology stays up to date with the latest security standards.

What Is Decryption?

Decryption is the process of converting ciphertext (scrambled text) back to plain text, making it readable again. The decryption process requires a decryption key, which is typically the same as the encryption key used to encrypt the data. This key is essential to the process of decryption and is generated during the encryption process.
There are two types of keys used in the decryption process: master keys and recovery keys. A master key is used to decrypt the data when paired with the correct password or hardware key (e.g. USB). It should be kept confidential and never shared with anyone. A recovery key, on the other hand, is a string of characters that can be used to decrypt an encrypted drive if the user forgets or loses their password.
While drive encryption is an effective way to protect data, it is important to note that it is not foolproof. Mistakes during the encryption or decryption process can result in the loss of data, which is why it is crucial to work with an experienced professional. Attempting to encrypt or decrypt a drive without the necessary expertise can lead to irreversible damage and the loss of important information.
To ensure that sensitive data is kept safe, it is recommended to hire a specialist who can handle the encryption and decryption process and manage recovery keys. A professional can also help with selecting the appropriate encryption method and ensure that all necessary precautions are taken to protect the data from unauthorized access.

Risks And Limitations Of Encryption

Encryption is a powerful tool for protecting sensitive data, but it’s important to understand its limitations and potential risks. Here are some of the key risks and limitations of encryption:

Key Management:

Encryption relies on keys to encrypt and decrypt data. The security of encryption is only as strong as the security of the keys used to encrypt and decrypt the data. If keys are lost or stolen, encrypted data can be lost forever.


No encryption method is completely secure. New vulnerabilities are discovered all the time, and even the most advanced encryption methods can be hacked by skilled attackers. It's important to keep software and hardware up-to-date and to use encryption methods that are well-known and trusted in the industry.

User Error:

Encryption is only effective if it is used correctly. A common user error is to store encryption keys on the same device as the encrypted data. If that device is stolen or compromised, the encrypted data is no longer secure.

Limited Scope:

Encryption only protects data while it is encrypted. Once the data is decrypted, it is vulnerable to attack. Encryption does not protect against other types of attacks such as malware or phishing.


Encryption can be complex and difficult to manage, particularly for non-technical users. It can also be resource-intensive, requiring significant processing power and storage capacity.

Legal Issues:

In some countries, the use of encryption is tightly regulated or even prohibited. Users need to be aware of local laws and regulations governing encryption and ensure they comply with them.

Encryption is a powerful tool for protecting sensitive data, but it is not a silver bullet. Users need to be aware of the risks and limitations of encryption and take appropriate steps to mitigate those risks. This includes using well-known and trusted encryption methods, keeping software and hardware up-to-date, and implementing appropriate key management practices.

BitLocker And FileVault

BitLocker and FileVault are essential tools for securing sensitive data stored on a computer or other devices. Both BitLocker and FileVault use strong encryption algorithms to prevent unauthorized access to encrypted data, and they are designed to work seamlessly with their respective operating systems, Windows and macOS. One of the most important features of these tools is the recovery key, which is a unique code that can be used to decrypt the drive in case of emergency, such as when a user forgets their password or loses their hardware key.
Windows-based computers that support BitLocker typically have a specialized chip known as a Trusted Platform Module (TPM). This chip is responsible for securely storing the encryption keys used by BitLocker, providing an extra layer of security to the encryption process. The TPM chip also helps protect against malicious software attacks by verifying the system’s integrity before allowing access to encrypted data.
Using BitLocker or FileVault to encrypt a drive is a highly effective way to protect sensitive data, but it is important to note that encryption alone is not enough. It is also essential to create strong passwords or use hardware keys, and to keep the recovery key in a safe place that is easily accessible in case of emergency. Additionally, it is recommended to hire an expert to assist with encryption, especially for individuals lacking experience with drive encryption, to prevent irreversible loss of data due to errors or mistakes in the encryption process
