Information Security Management System

Information Security Management System

HAMC' CSO (Chief Strategy Officer) oversees and manages the our information security management system and strategies. Notably, we have established a CISO (Chief of Information Security Officer) with over 5 years of experience in dedicated information security work under the CSO's office to manage the protection of all corporate information, including personal information. The security officers, HR Team, General Affairs Team, and Legal Compliance Team work together to increase awareness of the Security Policy throughout the company. In addition, we carry out support activities such as monitoring compliance of information protection & personal information protection regulations. Our holding company's security team, which is comprised of specialized security personnel, is in charge of periodic monitoring, risk management and corrective action requests. The security officer performs security activities and management monitoring, and reports the results to the Security Team. The Security Team evaluates, corrects and manages this.

KEY Performance Target

Information security pledge signed by all employees every year HS Hyosung Advanced Materials operates a security system that raises awareness of data protection and
prevents illegal use and leakage of data to protect valuable technology, personal, and asset data.

Technical Security

Cybersecurity

Cyberattacks such as the unauthorized reading of emails, distribution of hacked e-mails, establishment of infected websites, and spread of malicious codes are detected in real-time through security controls, and any incident is immediately shared with related departments to minimize damage. HS Hyosung Advanced Materials protects internal networks with firewalls and installs security programs, such as antivirus, to protect data from ransomware and other malicious attacks. Especially, logs generated from security solutions such as servers, network equipment, application program logs, and firewalls are managed cohesively in order to prevent log loss and tampering and securely store logs. Using the security information and event management(SIEM) solution, an alert is immediately triggered if an action exceeds the threshold value, followed by an immediate action. The SIEM rule and threshold value are periodically adjusted. Dedicated managers by stage review these security logs and upload their opinion to protect internal information and communication networks. The company blocks access to malicious IPs and URLs and protects in-house data from cyber threats by restricting access to non-work-related websites such as P2P lending sites.

Smart Data Leak Prevention System

HS Hyosung Advanced Materials' access control system prevents the leakage of our globally competitive technology and trade secrets by the invasion of external users. We block any unauthorized access by applying differentiation access control policies for the end user and system administrator, allowing only authorized persons to access the intranet. All work histories of internal network users are logged, and accounts are automatically locked when the number of login attempts exceeds a certain count. HS Hyosung Advanced Materials uses a virtual private network(VPN) to encrypt and protect the communication section when accessing the internal business system from outside the organization, such as when working from home, traveling, or during a business trip. We minimize the risk of cybersecurity incidents resulting from account data leakage by applying two-factor authentication with a unique one-time password(OTP). IP addresses other than the administrator ID are restricted to access the system server, and OTP verification is required in the server. According to the "Need-To-Know" principle, only those who have been authorized to access the work system via VPN from outside the organization when working from home due to COVID-19 and business trips. A separate approval process takes place for additional access authority. We record the commands performed on the server to prevent data leakage and swiftly identify the exact account of an incident. In addition, media control programs are used to prohibit the unauthorized copying of files stored on PCs to USB storage devices, and data loss prevention solutions are employed to prevent the unauthorized disclosure of sensitive data such as trade secrets. All files stored in PCs are restricted from bringing them outside the company without prior approval. History of file transfers and PC usage, including emails, are saved in the server even after they have been approved. This serves as evidence when an employee commits abnormal behaviors. We also control document exports and saving documents on PCs and monitor document distribution to strengthen document security and reduce the possibility of data leakage and loss.

Physical Security System

Places that require restricting unauthorized access by outsiders, such as offices and business sites, are designated as protected areas, and access records are managed by installing an ID card or fingerprint-based access system at the entrance. Areas that require particularly stringent access control (e.g. computer rooms) are designated as controlled areas, with security guards deployed or surveillance cameras installed. It is prohibited to carry out corporate assets or carry in a personal computer or storage media without prior authorization.

Centralized Document Management System

Modifying and storing security data are only allowed in our centralized document management system (enterprise content management; ECM), and only approved documents can be exported. Through ECM, we have established a consistent document security policy across all business sites, ensuring visibility throughout the document distribution process. The entire life cycle of a document is managed through the system, and all importing and sharing activities are centrally controlled and monitored by the system. Even when working from home, we provide an environment in which employees can access the centralized document management system and utilize work-related documents with ease, thereby enhancing the efficiency of telecommuting. Only personnel authorized by the team leader according the IT service request procedure are allowed to access ECM.

Compliance with Document Retention Period

HS Hyosung Advanced Materials stipulates the retention period of documents in accordance with its document management regulations and standards. We guide employees to discard expired documents and prevent data leakage during disposal.

Internalization of Security and Raising Security Awareness

Every year, HS Hyosung Advanced Materials conducts information security training for employees both online and offline, including awareness training of information breaches, personal data protection, customer data protection, and sharing of data breach cases, to enhance security awareness. Online training is provided to all employees once a year, and additional offline training is conducted once a year for the designated information security staffs at all teams. In addition, we inform employees of relevant regulatory updates and notifications through e-mail and company bulletin boards. We also improve accessibility to related education sources by creating pop-up windows announcing information security notice so that employees read the notice at least once a day when they log on to the company's IT platform.

Protection of Stakeholder Data

  • Privacy & Information
    Processing Policy

    In the process of collecting, using, and providing the data of employees, customers, and other stakeholders, HS Hyosung Advanced Materials goes to great lengths to safeguard the data so that data providers can enjoy our services without any concern. By allowing everyone to see the consent to the collection and use of personal data, we establish a business ecosystem that benefits both companies and data subjects.

    Easy-to-read Privacy & Information Processing Policy Move Page

  • Personal Data Protection of Stakeholders

    When collecting personal data of employees, customers, and partners, the data are collected only upon obtaining their consent, which includes items to be collected, the retention period, and the provision of the data to a third party. In addition, to store only necessary data, unused data are destroyed after a certain period of time. We keep the access logs of personal data to regularly check whether data whose retention period has expired are completely destroyed. When destroying personal data, we analyze if they have any chance of affecting other systems. We notify the data provider before destroying data to build a trustworthy relationship. In particular, we monitor any amendments made to applicable laws to reflect the changes in our policies, and we conduct personal data protection training once a year for personnel in charge of personal data handling.

  • Regular System Checkup

    All systems that contain personal data, such as websites and personal databases, conduct vulnerability tests regularly, and we conduct inspections and training of all departments, employees, and consignors who handle personal data. We continue to strengthen related processes so that employees can recognize the importance of personal data protection and utilize related policies and regulations in practice. Since 2021, we have voluntarily taken out liability insurance to fulfill our responsibility for damages in the event of personal data leakage.

  • Transparent Information Disclosure

    HS Hyosung Advanced Materials guarantees shareholders' rights to know and take part in disclosures to promote voluntary investment in information security. The status of information security such as investment, workforce, certification, and activities are disclosed for the safe use of the internet by various stakeholders.

Effective Information Security Risk Management

Information and Security Risk

HS Hyosung Advanced Materials has established and applied a systematic information security management system to protect all business-related trade secrets, core technologies, R&D information, customer information, and personal information. In order to respond to external infringements, we are implementing security management at all times or on a regular basis to the office area and process facility area through administrative/physical control. In addition, in order to prepare for external security attacks, including hacking, in real time, we regularly inspect security vulnerabilities, conduct mock hacking, and implement related trainings for employees to continuously improve our security level and response capabilities. HS Hyosung Advanced Materials provides information security education to employees at least once a year to raise the awareness among employees about security.

Information Security Vulnerabilities Check

In the case of introducing or changing an information system, HS Hyosung Advanced Materials reviews the system beforehand to minimize any security risk. Even when network control policies are modified, such as when the web server is opened to the public, security reviews are carried out to prevent unauthorized access. Particularly, annual security vulnerability inspections on information systems such as servers, network equipment, and application programs take place, and any found are patched.

Security Accident Response Process

According to the operating standard for security incident response, HS Hyosung Advanced Materials classifies the incidents into eight: (1) Leakage, alteration, or damage of confidential or personal data; (2) Leakage, stealing, and destruction of information asset; (3) Service stops or delays due to malicious code; (4) Attacks against or intrusion into the company's information system by an unauthorized individual; (5) Misuse of internal resources by an insider or authorized outsider; (6) Attacks that make the information system reject the service(e.g. DDoS attack); (7) Unauthorized intrusion of a physically restricted area or internal computer network; and (8) other infringement incidents. We maintain a professional organization that can provide immediate support in case any security incident take place. The Computer Emergency Response Team(CERT) quickly takes action and manages the emergency communications network. In the event of a security incident, the case is handled in accordance with the Security Incident Response Standards which also include five-step response procedures.

Information Security Risk Assessment and Scenario-based Training

HS Hyosung Advanced Materials established a risk assessment plan that corresponds to the Business Continuity Operating Standards so as to identify and list information assets and assign an importance rating to each asset. Since 2021, we have been measuring risks that may arise from each asset to establish a strategy to deal with those risks, and conducting regular re-evaluations and simulation exercises to assess information security risks. Risk assessment is conducted on a regular basis according to the likelihood, impact, and vulnerability level of information security status. We prevent security incidents that may occur in the most vulnerable areas, as well as conduct IT security exercises and distribute the response guideline. To prevent security incidents such as hacking, we collect information on domestic and global intrusions through an external security company to prevent similar incidents and execute security control 24/7.

Information Security Consultation and Treatment

Employees are encouraged to report any internal data leaks and pre/post-security risks, as well as any inconvenience or questions while using internal systems to the IT Inquiry Center, the Security Team, or the dedicated Information Security TF. As cyberattacks are diversified, such as hacking, virus, personal data infringement, and illegal spam, HS Hyosung Advanced Materials operates an integrated counseling system called the "Whistleblowing Center" to minimize inconvenience caused to various stakeholders, including customers, partners, and employees.
