In this installment of L.R. Kimball’s series on Next Generation 9-1-1 (NG9-1-1) Security, or NG-SEC, we will discuss information classification and protection. Classification measures are in place to protect sensitive information. Types of sensitive information include personnel records and network configurations. Personal health information recorded from emergency calls may be protected as well. Unauthorized release of sensitive information may result in law suits, exposed networks, and the possibility of violating federal laws.
Information should be classified according to its level of sensitivity. The level of sensitivity determines the level of protection. What you should consider when classifying information:
- Policies
- Regulations
- Laws
- Mandates
L.R. Kimball observed that security policies do not exist among most 9-1-1 facilities visited. However, an informal policy was implemented at each facility. It appears to be commonplace among the 9-1-1 community at large to treat uncategorized information as sensitive when the classification is unknown. L.R. Kimball found that each facility bears its own variation of informal information classification and identification of sensitive information.
Additionally, several facilities have similarities when it came to treatment of security policies. For example, many facilities required signature and pickup on a specific type of information. Although most 9-1-1 facilities tends not to create the security policy for information classification, L.R. Kimball found it to be commonplace among most emergency responders to have some form of informal policy pertaining to information classification implemented.
Responsibility for classifying and protecting information should be clearly defined. The data owner and data custodian should be known and identified. The data owner is responsible for determining the value or sensitivity of the information and assigning classification, e.g. public, internal use only, restricted. The data owner should communicate appropriate access and safeguard requirements to the data custodian and users. The data custodian is responsible for applying the restrictions established by the data owner to ensure confidentiality, integrity, and availability is maintained.

Uncategorized information could lead to the release of sensitive information. Formalizing information and classification policies will reduce the possibility of accidental release of sensitive information.
Our next blog will highlight NG-SEC section 6, General Security.
