Cybersecurity threats are on the rise. According to a March 2021 Security Signals study, 83% of enterprises have experienced at least one firmware attack since 2019. Moreover, a Check Point cybersecurity report finds that ransomware attacks almost doubled in 2021 compared to 2020, largely due to the increase in remote work environments.
The size of your organization can also increase your risk. While organizations of any size are at risk, the more employees you have, the more chances there are for human error to occur.
At the enterprise level, your company is also at an increased risk of cybersecurity threats due to complex internal processes, interconnected systems, and multiple office locations.
With the growing threat from ransomware and data breaches, security professionals need to evaluate protocols and ensure measures are in place to protect critical data. In this article, we’ll explain what enterprise file encryption is, what it’s used for, and how it can help protect companies like yours from cybersecurity threats.
What is enterprise-level file encryption?
As the term suggests, file-based encryption protects data in files by making it inaccessible without a unique key. This is a more granular layer of protection than full-disk encryption, which works at the device level to prevent unauthorized access.
An enterprise file encryption strategy protects data across its lifecycle. This includes the following data states:
Data at rest. At-rest data is stored in a device or database and is not actively moving to other devices or networks.
Data in transit. Also known as data in motion, in-transit data is being transported to another location, whether it moves between devices, across networks, or within a company’s on-premises or cloud-based storage.
Data in use. Data that is in use is regularly accessed for operations such as processing, updating, and viewing the data.
Without encryption, each data state is vulnerable to theft and corruption due to unauthorized access.
Attackers often target data at rest because it’s easily accessible if proper protection controls are not in place. For example, an employee’s laptop can compromise your data integrity if they are not encrypting data stored on the device. If the laptop itself is stolen or lost, hard disk encryption will keep data inaccessible if a would-be attacker tries to mount the hard disk to another device.
Data in transit is susceptible to man-in-the-middle attacks, which intercept data on the way to its destination. For example, an attacker can access a network through an unsecure Wi-Fi router and capture or manipulate sensitive information.
Data in use is the most vulnerable state because it is directly accessed by one or more users. Without identity management tools, you are at an increased risk of an unauthorized individual trying to access the data.
Enterprise file encryption takes a comprehensive approach to data security, protecting all three states of your data, as well as data moving from one state to another.
The high costs of a data breach
Protecting sensitive data against cyber threats and data breaches is paramount. With today’s more distributed and remote workforces, enterprise organizations are frequently targeted in ransomware and firmware attacks.
Despite the risks, only 50% of organizations have a comprehensive encryption strategy in place. Another 37% have a limited encryption strategy, which means sensitive data could be at risk of unauthorized exposure.
Ransomware, data breaches, and other adverse cybersecurity events wreak havoc on an organization’s financial health. Research has found ransomware attacks average $4.62 million per event, and that doesn’t include the cost of the ransom itself. The other costs of ransomware are connected to the following:
Operational disruption and downtime. The cost of downtime following a ransomware event can be 50 times greater than the ransom demand. In 2020, the average ransom demand was $5,600, but the average cost of downtime was $274,200.
Recovery and rectification. Recovering from a ransomware attack cost organizations an average of $1.85 million in 2021, and it can take years to restore compromised data and systems.
Data loss. Even if you pay the ransom, you might not recover your data. For example, stolen data might be auctioned on the dark web whether or not the ransom was paid. In other cases, faulty decryption tools impact data recovery, and cybercriminals might not return stolen data after receiving the ransom money.
Like ransomware events, data breaches invoke a number of business and non-business costs. For the average $4.24 million security breach, the cost breaks down as follows:
Lost business revenue from system downtime, customer turnover, and reputational losses averages $1.59 million.
Detection and identification of the breach costs an average of $1.24 million.
Post-breach response efforts average $1.14 million.
Notifying regulatory agencies, key stakeholders, customers, and the general public of the data breach costs and average of $0.27 million.
How file encryption benefits your organization
File encryption gives companies like yours the ability to control user access and review system activity. Increasing visibility and control over organizational data can help reduce the risk of third-party and insider threats.
Access controls ensure that users have access to only what they need to do their job. Regular review of your user access controls can help you pinpoint insider threats, such as an employee who attempts to access data that is not relevant to their job role.
System activity monitoring gives you greater insight into data usage and access patterns. It can also enhance your overall security by identifying suspicious behaviors. For example, should an employee inadvertently let an attack in through a phishing scam, reviewing system activity will help IT admins quickly respond to and contain the threat.
Enterprise cybersecurity issues are not limited just to its employees and internal systems, but also to its third-party vendors. On average, a typical enterprise organization has around 5,800 third-party vendors. Each vendor that does not employ basic security controls can weaken your overall cybersecurity.
More than half of enterprise organizations have experienced a third-party data breach. The average costs of third-party data breaches are higher, increasing from $4.24 million per breach to $4.33 million per breach event.
Industry requirements and standards for file encryption
While file-level encryption is a good practice for overall data security, it may also be a requirement for your organization’s compliance with certain regulatory provisions.
Multiple industry and governmental regulations exist that specify how your data—including personally identifiable information (PII), protected health information (PHI), financial records, and other critical information—must be managed and protected.
Financial services industry requirements
The financial services industry is heavily regulated because of the high volume of sensitive customer information it collects. In fact, the financial sector is second only to healthcare when it comes to being targeted by malicious cyberactivity.
Applicable regulations include the following:
Gramm-Leach-Bliley Act (GLBA). The GLBA requires encryption of customer information both at rest and in transit on external networks. This applies to all financial institutions, which includes companies that provide financial products or services.
Federal Financial Institutions Examination Council (FFIEC). FFIEC guidelines require encryption of data at rest when the company’s risk assessment indicates that encryption is necessary.
Payment Card Industry Data Security Standard (PCI DSS). PCI DSS identifies compliance requirements for any organization that handles cardholder data, including data encryption.
Healthcare Industry Requirements
Healthcare is a heavily regulated industry to ensure the protection of patients’ health and safety. To safeguard protected health information (PHI) against unauthorized disclosure, the Health Insurance Portability and Accountability Act (HIPAA) contains the following provisions:
Any company that transmits PHI is subject to HIPAA requirements. This includes, but is not limited to, health plans, healthcare clearing houses, healthcare providers, and their associated business entities.
Document policies related to how you prevent HIPAA violations through the implementation of physical, technical, and administrative security measures.
Conduct self-audits and risk assessments to identify potential data vulnerabilities.
Encrypt PHI to NIST standards whether the data is at rest, in transit, or in use.
Encrypt data that is transmitted over an external network or stored off-site.
Implement access controls and user authentication when accessing, storing, and transmitting PHI using mobile devices.
Government Industry Requirements
Defense, military, and government industry regulations protect personal and sensitive information.
The US Federal Government requires non-miliary government agencies and government contractors to adhere to the Federal Information Processing Standards (FIPS):
Anyone who handles sensitive but unclassified (SBU) information is subject to FIPS compliance requirements.
FIPS security standards require rigorous testing to determine if a specific solution meets governmental regulatory requirements.
FIPS 140-2 is used to validate that a chosen encryption method meets the requirements necessary to protect SBU data.
The Federal Information Security Modernization Act (FISMA) compels federal agencies to implement information security practices that reduce the risk of unauthorized access and use of sensitive information:
Data systems must be encrypted to prevent the exploitation of potential vulnerabilities.
Federal organizations and government contractors identify implemented security policies in a system security plan.
Information systems and data are classified according to a range of risk levels.
Password keys must be changed regularly for data security.
