23.4. Destroy media containing SPI when it is no longer needed for business or legal reasons by following procedures including, but not limited to:
23.4.1. Disposal of media containing SPI so that it is rendered unreadable or undecipherable, such as by burning, shredding, pulverizing, or overwriting. Media sanitization processes should be implemented following the NIST 800-88 standard, where possible.
23.4.2. Disposal logs should be maintained that are secured and that provides an audit trail of disposal activities. The log will be kept for a minimum of ninety (90) days.
23.4.3. Certificates of destruction should be maintained for at least one year.
24. Messaging Security
24.1. All incoming email should be scanned for viruses, phishing attempts, and spam.
24.2. Outgoing email should have data loss prevention (DLP) monitoring in place.
24.3. Any messaging service must be approved by Information Security prior to usage and must include appropriate audit trails and encryption of data at rest and in transit. Data loss prevention (DLP) tools and processes should be implemented, where possible.
25. Removable Media
25.1. All removable media brought in from outside iCIMS should be scanned for viruses/malware prior to use. Any identified malware/viruses should be removed with the assistance of End User Support prior to use.
25.2. Sensitive Personal information (SPI) is prohibited on any kind of removable device, unless the device is encrypted following data encryption policy. Notwithstanding the foregoing, if stored or cached information resides on a removable device, Personnel will follow company policies and procedures, including acceptable use requirements as defined in the Employee Handbook and Data Security and Privacy Statement, to mitigate the risk of a Data Breach.
25.3. Individuals in sensitive positions, with access to SPI, SCI or customer data, should not store such data on removable media, unless required by their role and approved by Information Security.
