Data Privacy and Security: Concerns, Challenges, and Best PracticesData Privacy and Security: Concerns, Challenges, and Best PracticesData Privacy and Security: Concerns, Challenges, and Best Practices

Advanced computer networks and high-speed internet reinvented how businesses communicate, store data, and share resources, such as software and digital files. Virtually every modern office has computer networks and systems in place so that employees can internally share information and collaborate securely. However, with technical advancements come newfound vulnerabilities, and cybercrime is the biggest threat that companies face.

In 2021, the average healthcare data breach cost an average of $10.1 million per incident, according to CompTIA. Further, Security Intelligence reports that phishing attacks increased by 48% over the first two fiscal quarters of 2022. Those phishing attacks cost businesses approximately $12.3 million, according to estimates. No industry is immune from attacks either: In 2022, the top five most targeted industries were healthcare, financial services, retail, education, and energy and utilities, Tech Business News reports.

Considering the financial harm and other associated risks that cybercrime poses, it has motivated many companies to make cybersecurity a top priority not only for their own sake but also for their clients. Data privacy and data security are two main components of cybersecurity. Companies that wish to safeguard their data and information technology (IT) infrastructure need to understand the most relevant challenges and most effective best practices of these two concepts. Those who are interested in working to fight cybercrime should consider pursuing an advanced education in IT to develop the required skills and competencies.

Since they’re both rooted in the protection of data from cybercrime, the concepts of data privacy and data security are sometimes used interchangeably. However, when comparing data privacy vs. data security, several attributes set them apart.

Data privacy is defined in the cybersecurity and IT fields as the retention, collection, use, and deletion of data. By comparison, data security consists of the policies and methods used to protect private data from unauthorized access and use. For data to be private, it must also be secure.

Data security is what maintains the confidentiality, integrity, and availability of a company’s data. It can be thought of as a digital padlock that is only for those who have the correct credentials to access it. This begs the question of what data types are being secured and the methods of securing them. Data is divided into one of the four following categories:

Sensitive data may also be classified as confidential. Sensitive data typically consists of the following types:

Multiple methods of applying data security exist, and many companies employ a multitiered strategy when developing their data security structure. The following are some of the most common data security methods.

A data backup is a copy of the main files and databases that exist at a different location. It’s not uncommon for companies to have second, third, and fourth data backup locations. If primary data is stolen, corrupted, or otherwise fails, data backups ensure that companies have a fail-safe in place. Data backup is an example of resiliency: an organization’s ability to adapt to data security threats and recover its data.

Data loss prevention (DLP) software monitors activity and scans data for policy violations and other actions that appear out of the ordinary. When a policy violation or an anomaly occurs, DLP software either issues an automated response or creates an alert. For instance, an attempt to access secure files from outside would trigger the DLP software due to suspicious activity.

Data erasure uses specific software to permanently erase confidential or otherwise sensitive data, thus making it unrecoverable. A series of 0s, 1s, or other random digits overwrites the data. This is a far more effective method than simply deleting the data, which may still be recoverable. When recycling a computer, data erasure is typically a part of the standard protocols.

Access control designates who is allowed to access certain databases or files. This is done in two main ways. The first way is through authentication: the process of confirming that users are who they claim to be. The second way is through authorization: the process of ensuring that users who have authenticated their identity have access to the data and resources that they’re approved for. Many people set up two-factor authentication (2FA) on their smartphones and banking accounts to prevent unauthorized access.

Data masking is a method of securing data by making it unreadable. When obscuring data, data masking uses several techniques, including scrambling, substitution, and shuffling. Data masking is often used in scenarios in which data analysis, user training, or software testing is needed, but not with sensitive data.

The process of encryption often gets compared to data masking because the end result is the same — unreadable data. Using an encryption cipher or algorithm, this process converts readable plaintext into unreadable ciphertext. Without the encryption key, encrypted data is completely useless.

Data is a company’s entire knowledge base. It comprises everything from confidential information about products and services to sensitive information about employees. Most companies have proprietary information and customer data that must remain under lock and key; this is why data security is important. It ensures that sensitive data is never stolen or made public. Data security also ensures that organizations remain compliant with government and industry regulations.

Companies that fall victim to a data breach may incur the following:

Data privacy is defined in the cybersecurity and IT fields as the method of handling data, especially when referring to privacy best practices, regulations, and data protection laws. When discussing data privacy, it helps to think of it in terms of control. How data is handled, used, transferred, and stored all relate back to how much control an individual or a company has over the data. People have the right to select which pieces of information they wish to share about themselves, to what parties they wish to share them with, and when they want to share them.

Several laws and regulations govern data privacy, including the following:

Privacy is widely considered a basic human right, which is why several laws and regulations are in place to protect that right. The ability of an individual or organization to control their own data and how it’s used is why data privacy is so important. Further, data privacy is a necessary element when doing business with a company or an organization. Customers need the reassurance that a business won’t exploit their data by sharing or selling it without their permission.

When data privacy is compromised, it can lead to negative results, including the following:

A cyberattack can target any individual or organization, resulting in stolen or compromised data. Cyberattacks take many forms; this means that several data security measures must be implemented to defend against them. Below are some of the main cyber and data security threats.

A phishing scam targets individuals and company employees by using an email that appears to be from a familiar source, such as a co-worker, friend, family member, or company they do business with. The scammer attempts to trick the email recipient into revealing personal information about themselves. After obtaining this personal information, the scammer can use it to open new accounts, access existing accounts, or commit other forms of abuse.

Although cloud-based systems carry plenty of benefits and have advanced how organizations maintain their data, they aren’t without their vulnerabilities. One of the main vulnerabilities is misconfigurations: gaps or glitches in the cloud infrastructure that can be exploited. Another vulnerability is data theft and loss, which is particularly dangerous to cloud-based systems. Further, cyber criminals can exploit cloud-based servers that are out of compliance, have weak access management, or have vulnerable application programming interfaces (APIs). Data privacy and security careers addressing cloud-based systems are in high demand now that more companies have adopted cloud-based servers.

Malware is defined as any software specifically designed to disrupt a computer, network of computers, or server in a way that compromises data, grants unauthorized access to cybercriminals, restricts access to authorized users, or otherwise interferes with functionality. On a related note, one of the leading smartphone security concerns is malicious apps, which are various types of malware designed to impact cell phones.

Ransomware comprises various types of malware. Once ransomware has been installed on a device or network, it encrypts all the files and makes them inaccessible to users. Victims must pay a ransom (hence the name) within a certain time frame, or their data will be destroyed or otherwise made unrecoverable. CompTIA reports that ransomware attacks grew by 41% in 2022, making them one of the most common data security threats in IT.

Endpoint devices, such as computers, printers, smartphones, and tablets, are capable of remotely communicating with and connecting to secure networks. If an endpoint device is unprotected, it can be exploited and grant cyber criminals unauthorized access. Phishing scams and ransomware attacks are two of the biggest ongoing endpoint threats in cybersecurity.

Weak passwords remain one of the biggest vulnerabilities to secure networks. Cyber criminals have long been able to access networks due to passwords that are overly simple or that use a piece of easily obtainable personal information, such as a birthday or a pet’s name. Once a cyber criminal figures out a user’s password, they can access the user’s accounts, then change the passwords so that the user is locked out.

An attack from within an organization is deemed an internal threat. An internal threat can be an individual pretending to be an employee who has possession of their credentials. It can also be a current or former employee who has malicious intent against an organization. Negligent employees who don’t follow proper security protocols are also a threat to an organization.

Considering the various cyber threats that can impact individuals and organizations, government agencies all over the world stress the importance of establishing cybersecurity measures and following a system of best practices. Best practices for cybersecurity programs that the U.S. Department of Labor recommends include the following:
