CHAPTER 202INFORMATION SECURITY STANDARDS
SUBCHAPTER CSECURITY STANDARDS FOR INSTITUTIONS OF HIGHER EDUCATION
RULE §202.75Information Resources Security Safeguards

State institutions of higher education shall apply the following Information Resources Security Safeguards based on documented risk management decisions. Any exception to the following safeguards shall be approved, justified and documented in accordance with §202.71(c)(1)(H) and (d)(5) of this chapter.

  (1) Manage access to information resources to ensure authorized use.

  (2) Confidentiality of data and systems.

    (A) Confidential information shall be accessible only to authorized users. An information file or record containing any confidential information shall be identified, documented, and protected in its entirety in accordance with §202.70(1) of this chapter.

    (B) Information resources assigned from one institution of higher education to another, or from an institution of higher education to a contractor or other third party, at a minimum, shall be protected in accordance with the conditions imposed by the providing institution of higher education.

  (3) Identification/Authentication.

    (A) Each user of information resources shall be assigned a unique identifier except for situations where risk analysis demonstrates no need for individual accountability of users. User identification shall be authenticated before the information resources system may grant that user access.

    (B) A user's access authorization shall be appropriately modified or removed when the user's employment or job responsibilities within the institution of higher education change.

    (C) Information resources systems shall contain authentication controls that comply with documented institution of higher education risk management decisions.

    (D) Information resources systems which use passwords shall be based on industry best practices on password usage and documented institution of higher education risk management decisions.

    (E) For electronic communications where the identity of a sender or the contents of a message must be authenticated, the use of digital signatures is encouraged. Institutions of higher education should refer to guidelines and rules issued by the department for further information. (Ref. 1 TAC Chapter 203.)

  (4) Encryption. Encryption requirements for information storage devices and data transmissions, as well as specific requirements for portable devices, removable media, and encryption key standards and management shall be based on documented institution of higher education risk management decisions.

    (A) Confidential information that is transmitted over a public network (e.g.: the Internet) must be encrypted.

    (B) Confidential information stored in a public location that is directly accessible without compensating controls in place (e.g.: FTP without access control) must be encrypted.

    (C) Storing confidential information on portable devices is discouraged. Confidential information must be encrypted if copied to, or stored on, a portable computing device, removable media, or a non-agency owned computing device.

    (D) An institution of higher education may also choose to implement additional protections, which may include encryption, for other data classifications.

  (5) Auditing.

    (A) Information resources systems shall provide the means whereby authorized personnel have the ability to audit and establish individual accountability for any action that can potentially cause access to, generation of, modification of, or effect the release of confidential information.

    (B) Appropriate audit trails shall be maintained to provide accountability for updates to mission critical information, hardware and software and for all changes to automated security or access rules.

    (C) Based on the risk assessment, a sufficiently complete history of transactions shall be maintained to permit an audit of the information resources system by logging and tracing the activities of individuals through the system.

  (6) Systems development, acquisition, and testing.

    (A) Test environments shall be kept either physically or logically separate from production environments. Copies of production data shall not be used for testing unless the data has been authorized for public release or unless all custodians involved in testing are otherwise authorized access to the data.

    (B) Information security, security testing, and audit controls shall be included in all phases of the system development lifecycle or acquisition process.

    (C) All security-related information resources changes shall be approved by the information owner through a change control process. Approval shall occur prior to implementation by the institution of higher education or independent contractors.

  (7) Security Policies. Each institution of higher education head or his/her designated representative and information security officer shall create, distribute, and implement information security policies. The following policies are recommended; however, institutions of higher education may elect not to implement some of the policies based on documented risk management decisions and business functions. These policies are not all inclusive and may be combined topically.

    (A) Acceptable Use--Defines scope, behavior, and practices; compliance monitoring pertaining to users of information resources.

    (B) Account Management--Defines the rules for establishing user identity, administering user accounts, and establishing and monitoring user access to information resources.

    (C) Administrator/Special Access--Establishes rules for the creation, use, monitoring, control, and removal of accounts with special access privileges.

    (D) Application Security--Establishes processes and coding practices to ensure development, deployment, and maintenance of secure applications.

    (E) Backup/Recovery--Establishes the rules for the backup, storage, and recovery of electronic information.

    (F) Change or Configuration Management--Establishes the process for controlling modifications to hardware, software, firmware, and documentation to ensure the information resources are protected against improper modification before, during, and after system implementation.

    (G) Electronic communication--Establishes prudent and acceptable practices regarding the use of electronic communications for the sending, receiving, or storing of electronic messages. Ensures compliance with applicable statutes, regulations, and mandates.

    (H) Encryption--Establishes encryption controls for institution of higher education-specified data classifications (e.g., confidential information), portable devices, removable media, transmission security, and encryption key standards and management.

    (I) Firewall--Describes how to manage network traffic coming into and going out of the security domain. The firewall policy should address:

      (i) Virtual and physical architecture;

      (ii) Protocols and applications that are permitted through the firewall, both inbound and outbound;

      (iii) Traffic monitoring rule set;

      (iv) Assignment of responsibility for monitoring and enforcing the firewall policy;

      (v) Approval process for updating or changing rule sets; and

      (vi) Auditing and testing to verify a firewall's configuration, rule set accuracy, and effectiveness.

    (J) Incident Management--Describes the requirements for dealing with computer security incidents including prevention, detection, response, remediation, and reporting.

    (K) Identification/Authentication--Establishes the rules for verifying the identity of a user, process, or device, as a prerequisite for granting access to resources in an information system, e.g., something you know (password), something you have (coded identity card), or something you are (biometric information).
