Information Security Management and Compliance
Records Management Standard
Disposition of records shall be conducted in a timely manner following the retention period and based on their information classification level.
Failure to adhere to disposition schedules can lead to the unnecessary expenditure of resources to store, maintain, search for, and produce records. Records not disposed of at the end of their retention period remain subject to records requests under statute or legal proceedings.
Retention periods are counted form the date of creation of the record, unless other instructions (e.g., “3 years from termination”) are noted in the Records Retention Schedule. Disposition would normally occur following the end of the month of year that marks the end of the retention period; thus, disposition of a record for which the retention period ends on July 10 would take place as soon after July 31 as practicable.
There may be conditions under which records destruction must be deferred even if they have reached or exceeded the end of their retention period. These conditions include:
To protect the confidentiality of information and the related privacy rights of CSULB students, faculty, staff, donors, patrons, vendors, and others, Level 1 and Level 2 information contained in all software and/or computer files, storage media devices and hard copy must be sanitized prior to disposal. The sanitization process ensures that recovery of information is not possible. Several methods can be used to sanitize media; however, the two major types of sanitization are clearing and destroying.
Clearing information is a level of media sanitization that protects the confidentiality of information against a robust keyboard attack. Simple deletion of items does not suffice for clearing. Clearing must not allow information to be retrieved by data, disk, or file recovery utilities and must be resistant to keystroke recovery attempts executed from standard input devices and from data scavenging tools. Overwriting is an acceptable method for clearing media. The security goal of overwriting is to replace written data with random data.
There are several overwriting software products to overwrite storage space on media. CSULB Network Services provides software tools and instructions to securely clean the data from ATA based hard drives and other storage media. Overwriting cannot be used for media that are damaged or not rewritable. In such cases, media should be destroyed.
Recommendations for sanitizing media types are found in Attachment C – Media Sanitization Methods.
