Processes & Governance
- Regularly Review and Update Incident Response Plans: Have a clear, up-to-date incident response plan that outlines steps to be taken in case of a data breach.
- Conduct Regular Security Audits and Risk Assessments: Periodically review and assess your security posture and practices to identify and address vulnerabilities.
- Employee Training and Awareness Programs: Regularly train employees on security best practices, potential threats like phishing attacks, and the importance of following company policies.
- Develop and Enforce Strong Security Policies: Create comprehensive security policies covering aspects like acceptable use of company resources, data access, and breach reporting procedures.
- Regular Backups and Data Recovery Plans: Regularly back up critical data and have a robust disaster recovery plan to minimize data loss in case of a breach.
- Establezca un proceso de aprobación para los dispositivos móviles de los empleados. Con el aumento de las capacidades de los dispositivos de consumo, como los teléfonos inteligentes y las tabletas, se ha hecho fácil interconectar estos dispositivos con las aplicaciones y la infraestructura de la empresa. El uso de estos dispositivos para interconectarse con el correo electrónico, el calendario y otros servicios de la empresa puede difuminar los límites entre los controles de la empresa y los del consumidor. Los empleados que solicitan y reciben la aprobación para acceder a la información de la empresa a través de sus dispositivos personales deben entender y aceptar las limitaciones y los controles impuestos.
- Govern Internet Usage: Most people use the internet without a thought to the harm that can ensue. Employee misuse of the internet can place your company in an awkward, or even illegal, position. Establishing limits on employee internet usage in the workplace may help avoid these situations. Every organization should decide how employees can and should access the web. You want employees to be productive, and this may be the main concern for limiting internet usage, but security concerns should also dictate how internet guidelines are formulated.
- Gestionar el uso del correo electrónico: Muchas violaciones de datos son el resultado del mal uso del correo electrónico por parte de los empleados, lo que puede provocar la pérdida o el robo de datos y la descarga accidental de virus u otros programas maliciosos. Deben establecerse normas claras sobre el uso del correo electrónico, el contenido de los mensajes, el cifrado y la conservación de los archivos.
- Govern Social Media: All users of social media need to be aware of the risks associated with social media networking. A strong social media policy is crucial for any business that seeks to use social networking to promote its activities and communicate with its customers. Active governance can help ensure employees speak within the parameters set by their company and follow data privacy best practices.
- Oversee Software Copyright and Licensing: There are many good reasons for employees to comply with software copyright and licensing agreements. Organizations are obliged to adhere to the terms of software usage agreements and employees should be made aware of any usage restrictions. Also, employees should not download and use software that has not been reviewed and approved by the company.
- Secure Physical Access to Company Premises: Implement measures like keycard access, visitor logs, and surveillance to secure physical access to your business premises.
- Manage Use of Portable Media: Portable media, such as DVDs, CDs and USB "flash drives," are more susceptible to loss or theft. Allow only encrypted data to be downloaded to portable storage devices.
Data
- Keep Only What You Need: Reduce the volume of information you collect and retain to only what is necessary. Minimize the places you store personal data. Know what you keep and where you keep it.
- Destroy Before Disposal: Cross-cut shred paper files before disposing of private information. Also destroy CDs, DVDs and other portable media. Deleting files or reformatting hard drives does not erase data. Instead, use software designed to permanently wipe the drive, or physically destroy it.
- Safeguard Data: Lock physical records in a secure location. Restrict access to employees who need to retrieve private data. Conduct employee background checks and never give access to temporary employees or vendors.
- Safeguard Data Privacy: Employees must understand that your privacy policy is a pledge to your customers that you will protect their information. Data should only be used in ways that will keep customer identity and the confidentiality of information secure. Of course, your employees and organizations must conform to all applicable laws and regulations.
Legal
- Legal Compliance and Data Protection Laws: Stay informed about and comply with relevant data protection laws and regulations like GDPR, CCPA, etc.
- Report Security Incidents: A procedure should be in place for employees or contractors to report malicious malware in the event it is inadvertently imported. All employees should know how to report incidents of malware and what steps to take to help mitigate damage
The Significance of Breach Reporting:
Effective communication and prompt notification about breaches are essential for efficient remediation and recovery, as well as for meeting compliance and regulatory requirements.
Benefits of Breach Disclosure in Remediation:
Prompt breach reporting notifies all affected parties, both internal and external and mobilizes them as well as key stakeholders who are involved in recovery and remediation efforts, depending on the nature and scope of the attack or compromise. For instance, if your organization is breached via a third-party, you must be alerted at once to prepare and protect your business. Similarly, if a breach in your system could affect your client, they should also be notified as soon as possible.
Effective and speedy remediation lessens the impact of a data breach, protecting the company's reputation and business relationships. It also helps retain customer trust by promptly informing customers of the impact and the measures taken to prevent further damage.
Regulatory and Compliance Standards for Breach Disclosure:
Recent data protection laws, such as the EU's General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA), mandate timely breach disclosures.
Emerging regulations highlight the increasing importance of breach reporting. new regulatory actions are continuously emerging, underlining the growing importance of breach reporting. Failure to comply with the respective privacy and data protection regulations can result in hefty fines and further reputational damage. Some notable recent regulations have reporting deadlines and requirements for breach disclosure.
Here’s what some of them require:- GDPR - The GDPR asks companies to report breaches within 72 hours "where feasible" with the only exception being if the breach does not "result in a risk to the rights and freedoms of natural persons." If an organization delays in reporting the breach, reasons for the delay need to be provided. The GDPR has heavy fines for non-compliance. Depending on violations, fines can reach:
€10 million ($11 million) or 2% of annual turnover, whichever is higher
€20 million ($22 million) or 4% of annual turnover, whichever is higher
This all depends on the regulator’s investigation, the amount of negligence, and the severity of the breach.
- California Consumer Privacy Act (CCPA) - The CCPA requires companies to report breaches within 72 hours if unencrypted data is involved or if an unauthorized user has access to encryption keys of encrypted data. It also requires companies to notify the California AG if more than 500 California residents are affected.
- New York SHIELD Act ("Stop Hacks and Improve Electronic Data Security") - The "NYS Information Security Breach and Notification Act" says a disclosure must be made “in the most expedient time possible and without unreasonable delay...." but doesn’t specify a specific timeframe. It also allows companies to delay a disclosure if law enforcement believes the disclosure can impede a criminal investigation. As is the case with the CCPA, if the breach affects more than 500 New York Residents, the affected companies must tell the NY AG within 10 days. Companies who don’t comply with the act can face up to $5,000 per violation.
- Securities and Exchange Commission (SEC) requirements - In 2022, the SEC introduced cybersecurity-related requirements for the protection of investors and now requires companies to inform investors and shareholders of "material incidents" within four business days of discovery. More recently, in March 2023, the SEC proposed updates to its cybersecurity rules, imposing stringent disclosure requirements for covered entities and requiring affected institutions to adopt "written policies and procedures" for incident response that include informing affected individuals within 30 days.
- European NIS-2 Directive ("Network and Information Security, Version 2") - The EU regulation, NIS-2, entered into force on January 6, 2023 and introduced stringent supervisory measures and streamlined reporting obligations. Affected companies must now provide an initial notification within 24 hours of becoming aware of an incident to their reporting authority and within 72 hours, the company must provide an initial breach assessment. Within one month of the attack, companies are expected to provide a final report detailing the attack's scope as well as any mitigation efforts undertaken. NIS-2 fines can be as high as €10 million ($11 million) or 2% of the company's annual revenue, whatever is higher.
- State by State reporting requirements - All 50 US states have laws relating to reporting requirements for data breaches. Puerto Rico, Guam, the District of Columbia, and the Virgin Islands also have reporting and notification requirements in place. It would be impossible to cover all of these here, but the NCSL (National Conference of State Legislatures) maintains a list of the latest bills and acts on its website.
Improving Breach Reporting in Organizations - In an age of increased cyber risks, organizations must proactively enhance their breach reporting practices. Best practices include:
- Developing a clear policy and process for breach reporting.
- Designating key stakeholders and defining their responsibilities.
- Collaborating with third parties for improved response capabilities.
- Preparing for the new normal of frequent data breaches, as indicated by our cybersecurity assessment findings.
