Ahead of The Latest Threats
What Is Data Exfiltration?
Data exfiltration refers to the unauthorized transfer, copying or retrieval of sensitive or confidential data from an organization's network or system to an attacker-controlled server or other external location. This can occur via various methods, including the installation of malware or other malicious tools that steal data, exploiting vulnerabilities in a network, or physically stealing hardware or devices containing confidential business information.
Organizations with high-value data, such as healthcare, financial, hospitality and legal institutions, face a heightened risk of attacks leading to data exfiltration. Data exfiltration carries severe consequences for organizations, including financial and data loss, breach of compliance regulations, and serious reputational harm.
How Does Data Exfiltration Occur?
The most common data exfiltration methods used against organizations include:
Accidental Insider Threats
Insider threat incidents, whether accidental or malicious, are one of the top causes of data exfiltration. Besides trusted individuals with malicious intent, accidental insider threats are a serious concern for businesses, accounting for over one-third of all data breach. These incidents can occur when a user is tricked into interacting with a phishing email, exposing sensitive credentials or confidential data. In addition, weak or reused passwords, or a lack of multi-factor authentication (MFA), are common weaknesses that threat actors look for to infiltrate a user’s account.
Data Misuse
Data misuse, which can occur when users intentionally or unintentionally attempt to circumvent security controls or policies, is another leading cause of data exfiltration. For instance, an employee may use unsanctioned third-party software for their own convenience, resulting in unintentional data exfiltration. Employees can also exfiltrate corporate data via personal email accounts, cloud storage, printers, file-sharing sites, keyboard shortcuts, and other means.
Cloud Apps, Databases & Removable Storage Media
Databases and cloud apps are invaluable to attackers due to the high-value data they contain, and are frequently targeted by both insiders and external threat actors as a result. Even in the age of ubiquitous cloud storage, removable media is another common threat vector, and old-school data exfiltration methods like flash drives remain a pervasive threat.
Safeguards Critical Data with Encryption & Advanced Authentication
Data is a valuable asset for all businesses that should not be overlooked. Guardian Digital recognizes that data protection is a vital part of any successful cybersecurity strategy and has engineered a cloud email security solution that provides full-managed, end-to-end control of businesses’ email infrastructure, safeguarding sensitive data as it is sent or received over email with robust encryption and advanced authentication. Implementing the SPF, DKIM, and DMARC email authentication standards to the fullest, Guardian Digital EnGarde Cloud Email Security ensures that all email messages delivered are safe, legitimate, and indeed from who they claim to be. EnGarde’s proactive security system goes beyond traditional measures to protect sensitive data, analyzing and tracking sender reputation to enhance its protection against future attacks.
Closes Critical Gaps in Built-In Microsoft 365 & Google Workspace Email Security
Built-in email protection in Microsoft 365 and Google Workspace is unable to defend against malicious URLs and attachments that are not included in its static URL lists, and is thus ineffective alone in securing against data exfiltration due to human error. Given that one in 10 employees will click on a malicious link in a phishing email, often resulting in the compromise of sensitive data, implementing additional layers of proactive email protection is critical for all organizations.
Guardian Digital EnGarde Cloud Email Security’s intelligent auto-learn system leverages dynamic URL and file analysis to protect against phishing and other dangerous attacks, which frequently involve malicious links and attachments. The intuitive platform is also capable of identifying conversation-style anomalies to detect stealthy spear phishing and business email compromise (BEC) scams that often deceive users into sharing sensitive data with adversaries.
