How Plaintiffs Prove Negligence In Data Breach Lawsuits
A data breach does not always mean the company was legally negligent. Plaintiffs need to show that the organization had a duty to protect sensitive information, failed to use reasonable safeguards, and caused legally recognized harm. This process can involve looking at cybersecurity practices, company policies, state laws, industry standards, vendor relationships, and what the company knew before the attack. At Net Law Advocates, we help people whose information was compromised by possible cybersecurity failures. Our lawyers look into what happened before, during, and after a breach to see if there is evidence for a compensation claim.
What Does Negligence Mean In A Data Breach Lawsuit?
Negligence law generally requires a plaintiff to establish a duty, breach of that duty, causation, and legally recoverable damages. The precise requirements depend on the state law governing the case.
In cybersecurity cases, the main question is whether the organization took reasonable steps to protect the sensitive information it collected or stored. Even if a criminal hacker caused the attack, that does not automatically answer this question. A company might still be accused of having weak security that made the breach possible or let an attacker access information that better precautions could have protected.
We look at more than just whether a cyberattack happened. We check what information the defendant had, how sensitive it was, how it was stored, who could access it, what security measures were in place, if known problems were fixed, and if any warnings were ignored.
Establishing That The Defendant Owed A Duty To Protect Data
The first issue is duty. Businesses routinely receive sensitive information from employees and consumers, including Social Security numbers, financial records, login credentials, medical information, dates of birth, addresses, and government identification numbers.
A plaintiff may argue that the circumstances created a duty to use reasonable care in storing and protecting that information. State statutes can also be important evidence of the security obligations imposed on organizations.
For example, Illinois’ Personal Information Protection Act, 815 ILCS 530/45, requires covered data collectors maintaining personal information concerning Illinois residents to implement and maintain reasonable security measures against unauthorized access, acquisition, destruction, use, modification, or disclosure. The statute also addresses security requirements when personal information is disclosed under a contract.
California also has its own data-security laws, and other states have different rules about security, breach notifications, privacy, or certain types of information. Since Net Law Advocates works with clients across the United States, we look at the specific laws that apply to each person instead of assuming one state’s rules fit everyone.ly important.
Evidence of a breach of duty might include claims that the defendant did not fix known problems, had weak access controls, did not protect credentials well, set up systems incorrectly, failed to watch for suspicious activity, skipped employee security training, or did not properly oversee vendors.
The FTC’s Safeguards Rule illustrates how detailed cybersecurity obligations can become in regulated industries. Covered financial institutions must maintain a written information-security program designed to protect customer information. The FTC identifies measures including risk assessments, access controls, encryption, multifactor authentication, security monitoring and testing, employee training, and oversight of service providers.
These requirements do not mean every cybersecurity lawsuit has the same standard of care. They demonstrate why determining what constituted reasonable security requires examining the defendant, the information involved, the applicable law, and the circumstances existing before the breach.
Using Internal Records To Establish What The Company Knew
One of the most important questions can be what the defendant knew before the breach.
Cybersecurity problems rarely exist in isolation. A company may have received penetration-testing results, vulnerability reports, security audits, employee warnings, vendor notifications, previous intrusion alerts, or recommendations to upgrade outdated systems.
During litigation, evidence may potentially include security policies, internal communications, incident reports, risk assessments, audit records, system logs, vendor contracts, training materials, and other corporate records obtained through discovery.
A written cybersecurity policy alone does not establish that adequate security actually existed. The FTC has previously emphasized the importance of companies implementing their written security policies in practice, including meaningful oversight of third-party vendors.
If records show that decision-makers knew about a serious vulnerability and failed to correct it, that evidence may become highly relevant to the negligence analysis.
Connecting The Security Failure To The Data Breach
Proof of inadequate cybersecurity is only part of a negligence case. Plaintiffs generally must also establish causation. Suppose attackers gained access using compromised credentials. The investigation might examine whether multifactor authentication should have been required, whether unusual login activity generated alerts, whether access privileges were unnecessarily broad, and whether reasonable controls could have prevented or limited the intrusion.
Vendor breaches raise similar questions. Companies increasingly give outside service providers access to customer or employee information. Under the FTC Safeguards Rule, covered financial institutions have obligations concerning the selection, contractual requirements, and assessment of service providers that receive customer information.
Our attorneys examine the sequence of events to determine whether the defendant’s alleged failure can be connected to the unauthorized access and resulting exposure.
Proving That Plaintiffs Suffered Legally Recognized Harm
A plaintiff must also address injury and damages. This can become one of the most heavily disputed parts of data breach litigation.
The harm may include unauthorized transactions, identity theft, fraudulent accounts, costs incurred responding to fraud, lost business funds, damage associated with compromised accounts, and other financial losses. Depending on the governing law and circumstances, additional forms of injury or statutory relief may be available.
The nature of the compromised information matters. Exposure of a Social Security number, financial account credentials, medical information, or authentication information can create different risks from exposure of less sensitive information. Illinois law, for example, expressly identifies categories such as Social Security numbers, government identification numbers, financial account information, medical information, health-insurance information, biometric data, and certain online-account credentials within its definition of protected personal information.
Plaintiffs should preserve breach notifications, fraudulent transaction records, correspondence, credit reports, invoices, account alerts, and records of other consequences following an incident. Documentation can help establish both the existence and extent of the claimed harm.
Federal And State Laws May Affect A Data Breach Claim
There is no single federal statute that creates a universal private negligence claim for every data breach in the United States. Instead, data breach litigation can involve state common law, state privacy and data-security statutes, consumer-protection laws, contracts, and sector-specific federal requirements.
For example, the Gramm-Leach-Bliley Act and the FTC Safeguards Rule impose information-security requirements on covered financial institutions. The Rule requires administrative, technical, and physical safeguards appropriate to the institution and the sensitivity of customer information.
Section 5 of the Federal Trade Commission Act, 15 U.S.C. § 45, also gives the FTC authority concerning unfair or deceptive acts or practices, and the agency has used that authority in privacy and data-security enforcement. However, an FTC enforcement authority should not be confused with an automatic private right to sue under that statute.
State law can provide additional requirements. Illinois’ Personal Information Protection Act, for example, requires reasonable security measures and provides that a violation of the Act constitutes an unlawful practice under the Illinois Consumer Fraud and Deceptive Business Practices Act.
Which statutes and causes of action apply must therefore be determined case by case.
Why A Cyberattack Does Not Automatically Excuse A Company
Companies facing data breach litigation may argue that sophisticated criminals, rather than the company, caused the incident. The existence of criminal conduct is certainly relevant, but it does not necessarily answer whether the defendant exercised reasonable care.
Cyberattacks are a known business risk. The legal inquiry may therefore focus on whether the particular attack or vulnerability was reasonably foreseeable and whether appropriate safeguards could have prevented the intrusion or reduced its consequences.
The question is not whether a company could guarantee perfect security. No system can eliminate every cyber threat. The issue in a negligence case is generally whether the defendant acted reasonably under the applicable circumstances and whether an unreasonable failure caused the plaintiff’s injury.
