Section 1: Purpose


  1. The purpose of this policy is to define a security incident and to outline the steps to be taken as a response. These steps are designed to ensure that employees know and understand the actions that will be taken if our college network, equipment, or data are compromised. This policy includes the communication and actions that will include 精东影业视频 Computing Services, NSHE IT, System Computing Services (SCS), and outside entities. An IT security incident is defined as an event that impacts or has the potential to impact the confidentiality, availability, or integrity of 精东影业视频 information technology resources from outside or inside sources. Standards, procedures, and guidelines regarding IT security incident response are included in this document. Specific procedures vary depending on the type of incident, but all procedures include the following steps:
    1. Preparation
    2. Detection and Analysis
    3. Containment
    4. Eradication
    5. Recovery
    6. Post-incident Activity
  2. With all incidents, it is important to maintain a centralized incident handler to avoid miscommunication, duplication of work, freelance investigation that could impact services or evidence, etc. To this end, ALL incidents will be assigned to 精东影业视频 Computing Services who will be responsible for managing the response.
  3. For the purposes of these incident response procedures, incidents will be classified in three categories based upon the sensitivity of the data involved, legal issues, magnitude of the service disruption, threat, expanse, and public interest. The identified class of incident helps determine the level of internal notification required as well as the potential requirement under NRS for notification to affected individuals. It is assumed that Computing Services has authority to disconnect 精东影业视频 systems from the network if required to protect assets and/or reduce the magnitude and expanse of a breach. This will be done with notification provided to the President of 精东影业视频, Vice President of Administrative Services and General Counsel, Vice President of Academic and Student Affairs, and System Computing Services (SCS). Established service disruption notification procedures will be followed to communicate outages to users.
  4. The remainder of this document will provide for incident response procedures that will be followed for most types of incidents with the understanding that there is no practical way to account for all potential incidents. The incident response general flow is illustrated in APPENDIX A and is meant as a guideline rather than a rule.

  3. Incident Response Procedures for Copyright Infringement:
    SCS receives Copyright Infringement notifications for multiple NSHE campuses including 精东影业视频. Most notifications are received via e-mail to abuse or host master. When a notification is received:
    1. The 精东影业视频 Network Functional Area will open a ticket and review the IP address information to determine the appropriate routing of the infringement.
    2. Notification is sent to the 精东影业视频 Information Security Officer and the Director of Computing Services.
    3. If the IP address in question is assigned to another NSHE institution, K-12 school, or agency, send the complaint notification back to SCS.
    4. If the IP address in question is on a 精东影业视频 managed network, the ISO will be notified and a ticket will be assigned to the Network Admin Functional Area.
    5. The ISO shall promptly acknowledge notification of each infringement claim. If the claim fails to comply in supplying information, the ISO shall promptly attempt to contact the person making the notification or take other reasonable steps to assist in the receipt of the notification that substantially complies.
    6. The ISO will examine the notification for:
      1. Identification of the copyrighted work claimed to have been infringed.
      2. Identification of the material that is claimed to be infringing and that is to be taken down or disabled, and information reasonably sufficient to enable 精东影业视频 to locate the material.
      3. A statement that the complainant has a good faith belief that use of the material in the manner complained of is not authorized by the copyright owner, the owners agent, or the law.
      4. A statement that the complainant has a good faith belief that use of the material in the manner complained of is not authorized by the copyright owner, the owners agent, or the law.
      5. A statement that the information in the notification is accurate and that, under penalty of perjury, the complainant is authorized to act on behalf of the copyright owner.
      6. If the complaint meets the appropriate requirements, the ISO shall direct prompt removal of material or removal of all local or wide area network access to the material or activity claimed to be infringing.
      7. The ISO will take responsible steps to notify the alleged infringer promptly of the take-down. This notice will specify information required to make a counterclaim.
      8. The ISO may terminate access and exercise disciplinary and/or other correctional measures for any copyright infringement claim, including repeated claims and/or violations or flagrant misuse of 精东影业视频 information systems equipment or network connections and/or services.
  4. Incident Response Procedures Counter-notification
    If the person responsible for the alleged infringing distribution of copyrighted material believes the material was misidentified or the distribution was lawful, they should send a counter-notification to the ISO containing the following:
    1. A physical signature of the person responsible for the alleged infringing distribution.
    2. An incident handler will be assigned by the ISO and will gather information as per APPENDEX E: Risk Assessment Report standard.
    3. A statement under penalty of perjury that the alleged infringer has a good faith belief that the material was removed or disabled as a result of mistake or misidentification of the material.
    4. The alleged infringers name, address and telephone number, and a statement that the alleged infringer consents to the jurisdiction of the federal district court for the judicial district in which the alleged infringer is located and that the alleged infringer will accept service of process from the complainant.
    5. Once the complaining party receives the claim, the DMCA permits 精东影业视频, as a service provider, to restore materials or access within two weeks unless the complaining party serves notice that it intends to seek a court order to restrain infringement. 精东影业视频, NSHE, or SCS policy may mandate for other reasons that materials or access not be restored, and that other investigation, containment, or disciplinary measures proceed.
  5. Incident Response Procedure for Suspicious Activity (Examples: sweeps, scans, unusual connections, excessive bandwidth consumption)
    Sweeps and scans are common occurrences however, a sweep/scan coming from a 精东影业视频 institutional network against SCS controlled resources, specifically iNtegrate, or from within SCS can indicate a compromised system.
    1. A ticket will be opened and assigned to the ISO.
    2. An incident handler will be assigned by the ISO and will gather information as per Policy Documents: Risk Assessment Report standard.
    3. If the scan/sweep is coming from a 精东影业视频 Institution, the ISO from SCS will inform the appointed ISO and provide the information gathered by the SCS incident handler.
    4. If the same IP address continues to scan/sweep SCS resources, specifically iNtegrate, after notification, the 精东影业视频 ISO will instruct that IP address be blocked via firewall or router ACL.
    5. If the scan/sweep originates from within 精东影业视频 and is not authorized by the 精东影业视频 ISO, an investigation will be conducted to determine the cause of the scan/sweep and if violation of Acceptable Use or 精东影业视频 Computer Use policy has occurred. The ISO will notify the Computing Services Director and the Vice President of Administrative Services and the Vice President of Academic and Student Affairs regarding any such violation of policy and investigation.
    6. Excessive bandwidth consumption and unusual connections are most often discovered through network reports, SIEM and IDS alerts and other network monitoring tools. Upon report of such suspicious activity:
      1. A ticket will be opened and assigned to the ISO.
      2. An incident handler will be assigned by the ISO and will gather information as per APPENDEX E: Risk Assessment Report standard.
      3. Incident handler will, with the assistance of need-to-know internal technical experts if required, perform an initial assessment depending on the OS, application, symptoms, and role of system.
    7. DO NOT USE COMMANDS ON COMPROMISED SYSTEM!
    8. Write down each command performed on any live system.
    9. Minimize any actions that write to disk.
    10. Gather and save any pertinent log information including but not limited to:
      1. Local application, security, system logs
      2. Anti-virus log files
      3. Network, IDS, SEIM logs
    11. Record network connections using known good command (from secured USB device).
    12. Record all running processes using known good command (from secured USB device).
    13. On workstations, provide an inventory list of for the system in question.
    14. Create a forensic image using authorized tools if:
      1. Compromise may lead to criminal investigation
      2. If system needs to get back online quickly by re-installing (investigation may continue)
      3. If compromise may lead to legal or HR/Personnel related investigation
      4. If cause of compromise is not readily known and more detailed investigation is needed
  6. Notification
    Per NRS 603A.220 (APPENDIX I) notification of a data breach must be provided to the owner of the PII of any breach of the security of the system data immediately following discovery if the personal information was, or is reasonably believed to have been, acquired by an unauthorized person.
    1. Notification methods may include:
      1. Written notification
      2. Electronic notification, if the notification provided is consistent with the provisions of the Electronic Signatures in the Global and National Commerce Act.
      3. Substitute notification, if the data collector demonstrates the cost of providing notification would exceed $250,000, the affected class of subject persons to be notified exceeds 500,000 or the data collector does not have sufficient contact information.
        Substitute notification must consist of all the following:
        • Notification by electronic mail when the data collector has electronic mail addresses for the subject persons.
        • Conspicuous posting of the notification on the Internet website of the data collector, if the data collector maintains an Internet website.
        • Notification to major statewide media.
    2. If any incident is determined to meet or believed to meet the definition of a data breach of personally identifiable information as per Nevada Revised Statute, the ISO will notify the Vice President of Administrative Services and General Counsel who shall determine the appropriate course of action to comply with State law.
  7. Post Incident
    1. After an incident has been resolved it is important that Computing Services review the response to improve the incident response procedures. The lessons learned review should be conducted within two weeks of the incident closure for Class 2 and Class 3 incidents.
      1. The incident handler assigned to the incident will summarize the incident and the results of the response.
      2. The ISO will send a summary to the Vice President of Administrative Services and General Counsel.
      3. The incident handler will schedule a meeting of Computing Services
      4. The incident response team will determine action items necessary to improve the incident response procedures.
      5. Computing Services will update and publish current documentation within 30 days of the Post Incident Review.
    2. Note: Incidents involving personnel should remain confidential and therefore will not be subject to this review. Incident review when PII data, legal or law enforcement matters are involved will be conducted at the discretion of the Vice President of Administrative Services and General Counsel
  8. Incident Documentation
    1. When a potential incident is reported to the ISO and assigned an incident handler, the first step is to classify the incident and initiate the appropriate response procedures. This involves gathering information and documenting the incident; assessing the reported information to determine the severity, and determining the incident type. See APPENDIX H for Data for Incident Documentation Reporting.
