DoD Public Key Infrastructure (PKI) Tokens

Definition and purpose of PKI tokens

The Department of Defense Public Key Infrastructure (PKI) token is a crucial component in securing sensitive information and systems within the military network. These tokens are physical devices, such as USB drives or key fobs, that store digital certificates and cryptographic keys. The main purpose of DoD PKI tokens is to provide secure authentication and authorization to access DoD networks and resources.

PKI tokens play a vital role in implementing robust security measures for accessing classified systems, the NIPRNet (Non-secure Internet Protocol Router Network), and the SIPRNet (Secret Internet Protocol Router Network). They are designed to meet the stringent security standards and protocols required by the Department of Defense.

Components of DoD PKI tokens

At the heart of every DoD PKI token is a secure element, which is a specialized chip designed for cryptographic operations. This secure element ensures that the cryptographic keys are kept separate from the token’s operating system, making them nearly impossible for malware or unauthorized individuals to access.

The DoD PKI operates as a hierarchical system on the NIPRNet, with a Root Certification Authority (CA) at the top and several issuing CAs that provide scalability and disaster recovery capabilities. This infrastructure issues certificates for Common Access Cards (CACs) and software certificates to meet various application requirements.

On the SIPRNet, the DoD operates CAs under the National Security System (NSS) PKI Root CA, which supports all federal agencies with users or systems on secret networks. The NSS PKI issues certificates for SIPRNet hardware tokens and software certificates to address specific application needs.

Security features of PKI tokens

DoD PKI tokens offer several security features that make them highly effective in protecting sensitive information:

Two-factor authentication (2FA): PKI tokens require both the physical device and a PIN for login, adding an extra layer of security beyond traditional username and password combinations.
Digital signatures: The tokens enable users to digitally sign emails and documents, ensuring data integrity and non-repudiation.
Encryption capabilities: PKI tokens allow for the encryption of sensitive information, ensuring confidentiality during transmission and storage.
Centralized management: The DoD PKI and NSS PKI provide centralized infrastructures for managing keys and certificates throughout their lifecycle, from issuance to revocation or expiration.
Directory services: These infrastructures support directory services that provide CA certificates, certificate revocation information, and user encryption certificates.

The implementation of DoD PKI tokens has had a significant impact on military network security. It has improved intrusion detection and protection by facilitating the creation of secure network domains using Non-Person Entity (NPE) certificates for workstations, web servers, and devices.

By utilizing PKI tokens, authorized personnel can securely access restricted websites, enroll in online services, and encrypt/decrypt and digitally sign emails across various DoD networks. This comprehensive approach to security helps maintain the integrity and confidentiality of classified systems while enabling efficient communication and information sharing among DoD members, coalition partners, and other authorized users.

Appropriate Uses of DoD PKI Tokens

Accessing secured military networks

DoD Public Key Infrastructure (PKI) tokens play a crucial role in enabling authorized personnel to access secured military networks. These tokens provide authenticated identity management, allowing DoD members, coalition partners, and other authorized users to securely access restricted websites and enroll in online services. The tokens are essential for accessing both the Non-secure Internet Protocol Router Network (NIPRNet) and the Secret Internet Protocol Router Network (SIPRNet).

On the NIPRNet, Common Access Cards (CACs) serve as the primary hardware token for identifying individuals and granting logical access to resources. The DoD PKI operates as a hierarchical system on this network, with a Root Certification Authority at the top and several issuing CAs that provide scalability and disaster recovery capabilities.

For the SIPRNet, which handles classified information, the DoD operates Certification Authorities under the National Security System (NSS) PKI Root CA. This infrastructure supports all federal agencies with users or systems on secret networks. SIPRNet tokens, which are PIN-protected, allow authorized individuals to access resources over globally dispersed SIPRNet nodes securely.

Digital signatures for official documents

One of the key features of DoD PKI tokens is their ability to facilitate digital signatures for official documents. This capability ensures the integrity and authenticity of electronic communications and documents within the military infrastructure. Digital signatures provide a way to verify that the sender is who they claim to be and that the content has not been altered during transmission.

Commanders at all levels use DoD PKI to enable DoD members and authorized personnel to digitally sign emails and other official documents. This process helps to maintain the chain of custody for sensitive information and supports non-repudiation, which is crucial in military operations and communications.

Encrypting sensitive communications

DoD PKI tokens are instrumental in encrypting sensitive communications across military networks. This encryption capability is vital for maintaining the confidentiality of classified information and protecting it from unauthorized access or interception.

Authorized users can utilize their PKI tokens to encrypt emails and other forms of electronic communication. This ensures that sensitive information remains secure during transmission and can only be accessed by intended recipients who possess the appropriate decryption keys.

The encryption capabilities provided by DoD PKI tokens are particularly important for communications on the SIPRNet, where classified information is routinely exchanged. By using these tokens, military personnel can securely share sensitive data, operational plans, and other critical information without compromising national security.

In addition to email encryption, DoD PKI tokens support the encryption of information in transit through various protocols, such as Transport Layer Security (TLS). This comprehensive approach to encryption helps to create a secure environment for the exchange of sensitive military information across different networks and systems.

By enabling these appropriate uses, DoD PKI tokens serve as a cornerstone of information security within the Department of Defense, ensuring that only authorized personnel can access, sign, and encrypt sensitive military communications and documents.

Inappropriate Uses and Security Risks

While DoD Public Key Infrastructure (PKI) tokens are essential for securing military networks, their misuse can lead to significant security vulnerabilities. Understanding the inappropriate uses and associated risks is crucial for maintaining the integrity of classified systems and protecting sensitive information.

Using tokens on public computers

One of the most significant risks associated with DoD PKI tokens is their use on untrusted or public computers. When a DoD personnel inserts their token into a potentially compromised device, they expose themselves to a host of security threats. Malicious software on these machines can exploit the token’s functionality without needing physical access to the private key.

For instance, viral infections on home PCs pose a considerable risk. According to a report, a substantial percentage of Windows computers are infected with at least one backdoor Trojan. This means that when DoD personnel use their tokens on personal devices for email signatures or authenticated SSL connections, they become vulnerable to various attacks.

These attacks can range from simple PIN phishing to more sophisticated exploits. Malware can capture the PIN as it’s entered, transmitting it along with the token’s serial number to hackers. This information can then be used to compromise the token if it’s ever stolen.

Sharing tokens with others

Sharing DoD PKI tokens with others is strictly prohibited and poses a severe security risk. Users are responsible for maintaining positive control of their tokens and must not allow others to access their CLO-enabled SIPRNet accounts. This rule is crucial because sharing tokens can lead to unauthorized access to classified information and compromise the integrity of secure communications.

When a token is shared, it becomes impossible to maintain accountability for actions performed using that token. This situation undermines the principle of non-repudiation, which is essential in military operations and communications. Moreover, shared tokens can lead to unintended data exposure and potentially compromise entire networks.

Using tokens for personal activities

DoD PKI tokens are designed for official use only and should never be used for personal activities. Using these tokens for non-work-related tasks increases the risk of exposure to malicious actors and can lead to unintended consequences.

For example, if a user employs their token to access personal email or social media accounts, they may inadvertently expose sensitive information or create vulnerabilities that can be exploited by cybercriminals. Additionally, using tokens for personal activities can blur the line between official and personal communications, potentially leading to security breaches or policy violations.

To mitigate these risks, DoD personnel must treat their PKI tokens with the same level of care as they would a Common Access Card (CAC). This includes reporting any loss, theft, or damage immediately and returning tokens when they are no longer needed for SIPRNet access or upon command check-out.

By understanding and avoiding these inappropriate uses, DoD personnel can help maintain the security of classified systems and ensure the proper handling of sensitive information across military networks.

Best Practices for DoD PKI Token Usage

These practices help maintain the integrity of classified systems and prevent unauthorized access to sensitive data on networks like NIPRNet and SIPRNet.

Proper storage and handling

DoD PKI tokens, including SIPRNet tokens, require careful handling and storage to maintain their security. Authorized personnel should treat these tokens with the same level of care as they would a Common Access Card (CAC). It’s essential to keep the token in a secure location when not in use and never leave it unattended or inserted into a computer system.

Users must maintain positive control of their tokens at all times. This means keeping them on their person or in a locked drawer when not actively using them for PKI-required tasks. It’s crucial to remember that these tokens should only be used within their designated classification level. For instance, never use a SIPRNet token on the NIPRNet or vice versa.

Regular updates and maintenance

To ensure the continued effectiveness of DoD PKI tokens, regular updates and maintenance are necessary. This includes keeping the associated systems and software up to date with the latest security patches and firmware versions. For mobile endpoints with DoD Mobile PKI Credentials, it’s important to update to the most recent operating system, security patch level, and firmware versions within 30 days of their public release.

DoD enterprise management systems should enforce compliance monitoring to ensure that mobile endpoints’ configuration settings do not deviate from the approved baseline. This includes checking for proper STIG configurations, approved OS versions, and ensuring devices are not rooted or jailbroken.

It’s also important to note that mobile endpoints that no longer receive the latest patches or updates from the vendor or carrier should be considered end-of-life. These devices should be retired from service and wiped of all DoD information to maintain the security of classified systems.

Reporting lost or compromised tokens

In the event that a DoD PKI token is lost, stolen, or potentially compromised, immediate action is crucial to protect sensitive information and maintain the security of DoD networks. Users must report any tampering, damage, or loss of their token to their security point of contact without delay.

DoD enterprise management system owners and Authorizing Officials (AOs) must have a documented process in place to ensure that mobile endpoints are remotely wiped and the DoD Mobile PKI Credentials are revoked if a device is tampered with, damaged, or lost. This process helps prevent unauthorized access to classified systems and protects sensitive data on networks like NIPRNet and SIPRNet.

If a user loses their CAC, they can continue to use their DoD Mobile PKI Credentials on their mobile endpoint or authenticator. However, upon being issued a new CAC, the user will need to recover their new encryption keys. In cases where a mobile endpoint or authenticator with DoD Mobile PKI Credentials is lost, users may be required to obtain new encryption keys to maintain the security of their access to DoD networks.

By following these best practices, authorized personnel can help ensure the appropriate use of DoD Public Key Infrastructure tokens and maintain the security of classified systems across DoD networks.

The appropriate use of DoD Public Key Infrastructure tokens is crucial to maintaining the security of classified systems and protecting sensitive information across military networks.
