The IBM Aspera Platform must be configured to support centralized management and configuration.
Medium Severity
<VulnDiscussion>Without the ability to centrally manage the content captured in the audit records, identification, troubleshooting, and correlation of suspicious behavior would be difficult and could lead to a delayed or incomplete analysis of an ongoing attack. The content captured in audit records must be managed from a central location (necessitating automation). Centralized management of audit records and logs provides for efficiency in maintenance and management of records, as well as the backup and archiving of those records. Network components requiring centralized audit log management must have the capability to support centralized management. The DoD requires centralized management of all network component audit record content. This requirement does not apply to audit logs generated on behalf of the device itself (management). Support of centralized management of the IBM Aspera Platform is accomplished via use of IBM Aspera Console.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
SRG-NET-000131-ALG-000085
1 Rule
<GroupDescription></GroupDescription>
The IBM Aspera Platform must not have unnecessary services and functions enabled.
Medium Severity
<VulnDiscussion>Information systems are capable of providing a wide variety of functions (capabilities or processes) and services. Some of these functions and services are installed and enabled by default. The organization must determine which functions and services are required to perform the content filtering and other necessary core functionality for each component of the ALG. These unnecessary capabilities or services are often overlooked and therefore may remain unsecured. They increase the risk to the platform by providing additional attack vectors. The primary function of an ALG is to provide application specific content filtering and/or proxy services. The ALG application suite may integrate related content filtering and analysis services and tools (e.g., IPS, proxy, malware inspection, black/white lists). Some gateways may also include email scanning, decryption, caching, and DLP services. However, services and capabilities which are unrelated to this primary functionality must not be installed (e.g., DNS, email client or server, FTP server, or web server). Next Generation ALGs (NGFW) and Unified Threat Management (UTM) ALGs integrate functions which have been traditionally separated. These products integrate content filtering features to provide more granular policy filtering. There may be operational drawbacks to combining these services into one device. Another issue is that NGFW and UTM products vary greatly with no current definitive industry standard.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
SRG-NET-000339-ALG-000090
1 Rule
<GroupDescription></GroupDescription>
IBM Aspera Console must implement multifactor authentication for remote access to non-privileged accounts such that one of the factors is provided by a device separate from the system gaining access.
Medium Severity
<VulnDiscussion>For remote access to non-privileged accounts, the purpose of requiring a device that is separate from the information system gaining access for one of the factors during multifactor authentication is to reduce the likelihood of compromising authentication credentials stored on the system. Multifactor solutions that require devices separate from information systems gaining access include, for example, hardware tokens providing time-based or challenge-response authenticators and smart cards such as the U.S. Government Personal Identity Verification card and the DoD common access card. A privileged account is defined as an information system account with authorizations of a privileged user. Remote access is access to DoD-nonpublic information systems by an authorized user (or an information system) communicating through an external, non-organization-controlled network. Remote access methods include, for example, dial-up, broadband, and wireless. An example of compliance with this requirement is the use of a one-time password token and PIN coupled with a password; or the use of a CAC/PIV card and PIN coupled with a password. Satisfies: SRG-NET-000339-ALG-000090, SRG-NET-000340-ALG-000091, SRG-NET-000349-ALG-000106</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

1 Rule
<GroupDescription></GroupDescription>
The IBM Aspera Console must protect audit information from unauthorized read access.
Medium Severity
<VulnDiscussion>Auditing and logging are key components of any security architecture. Logging the actions of specific events provides a means to investigate an attack, recognize resource utilization or capacity thresholds, or to simply identify an improperly configured network element. Thus, it is imperative that the collected log data from the various network elements, as well as the auditing tools, be secured and can only be accessed by authorized personnel. This does not apply to audit logs generated on behalf of the device itself (management). Satisfies: SRG-NET-000098-ALG-000056, SRG-NET-000099-ALG-000057, SRG-NET-000100-ALG-000058</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

1 Rule
<GroupDescription></GroupDescription>
The IBM Aspera Console must protect audit tools from unauthorized access.
Medium Severity
<VulnDiscussion>Protecting audit data also includes identifying and protecting the tools used to view and manipulate log data. Therefore, protecting audit tools is necessary to prevent unauthorized operation on audit data. Network elements providing tools to interface with audit data will leverage user permissions and roles identifying the user accessing the tools and the corresponding rights the user enjoys in order make access decisions regarding the access to audit tools. Audit tools include, but are not limited to, vendor-provided and open source audit tools needed to successfully view and manipulate audit information system activity and records. Audit tools include custom queries and report generators. This does not apply to audit logs generated on behalf of the device itself (management). Refer to the IBM Aspera Console Admin Guide for data requirements for the SAML assertion including default attribute names, the IBM Aspera Console User Field, and required format within the assertion.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

1 Rule
<GroupDescription></GroupDescription>
IBM Aspera Console must be configured with a preestablished trust relationship and mechanisms with appropriate authorities (e.g., Active Directory or AAA server) which validate user account access authorizations and privileges.
Medium Severity
<VulnDiscussion>User account and privilege validation must be centralized in order to prevent unauthorized access using changed or revoked privileges. IBM Aspera Console must use an IdP for authentication for security best practices. The IdP must not be installed on the IBM Aspera Console virtual machine, particularly if it resides on the untrusted zone of the Enclave. Refer to the IBM Aspera Console Admin Guide for data requirements for the SAML assertion including default attribute names, the IBM Aspera Console User Field, and required format within the assertion. For security best practices also ensure that the system hosting IBM Aspera Console uses Network Time Protocol or another system to keep times synchronized with the IdP/SAML Provider providing the SAML assertions. Clock drift between The IBM Aspera Console server and the IdP/SAML Provider will result in expired assertions and the inability to be successfully authenticated into IBM Aspera Console. Satisfies: SRG-NET-000138-ALG-000063, SRG-NET-000138-ALG-000088, SRG-NET-000138-ALG-000089, SRG-NET-000140-ALG-000094, SRG-NET-000147-ALG-000095</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
SRG-NET-000062-ALG-000011
1 Rule
<GroupDescription></GroupDescription>
The IBM Aspera Console feature must be configured to use encryption services that implement NIST FIPS-validated cryptography to protect the confidentiality of remote access sessions.
High Severity
<VulnDiscussion>Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote access session. Remote access is access to DoD nonpublic information systems by an authorized user (or an information system) communicating through an external, non-organization-controlled network. Remote access methods include broadband and wireless connections. Remote access methods include, for example, proxied remote encrypted traffic (e.g., TLS gateways, web content filters, and webmail proxies). Encryption provides a means to secure the remote connection so as to prevent unauthorized access to the data traversing the remote access connection, thereby providing a degree of confidentiality. The encryption strength of the mechanism is selected based on the security categorization of the information. This requirement applies to ALGs providing remote access proxy services as part of its intermediary services (e.g., OWA or TLS gateway). For implementations using the IBM Aspera Console feature, the default configuration of Console has TLS 1.0 and 1.1 enabled to support older browsers.

<GroupDescription></GroupDescription>
IBM Aspera Console interactive session must be terminated after 10 minutes of inactivity for non-privileged and privileged sessions.
Medium Severity
<VulnDiscussion>Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port that has been left unattended. In addition, quickly terminating an idle session will also free up resources committed by the managed network element.

<GroupDescription></GroupDescription>
IBM Aspera Console must prevent concurrent logins for all accounts.
Medium Severity
<VulnDiscussion>Limiting the number of current sessions per user is helpful in limiting risks related to DoS attacks. This requirement addresses concurrent sessions for information system accounts and does not address concurrent sessions by single users via multiple system accounts. The maximum number of concurrent sessions must be the same as the requirements specified for the application for which it serves as intermediary. This policy only applies to application gateways/firewalls (e.g., identity management or authentication gateways) that provide user account services as part of the intermediary services.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

IBM Aspera Console passwords must be prohibited from reuse for a minimum of five generations.
Medium Severity
<VulnDiscussion>Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. If the information system or application allows the user to reuse their password consecutively when that password has exceeded its defined lifetime, the end result is a password that is not changed per policy requirements.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

IBM Aspera Console user account passwords must have a 60-day maximum password lifetime restriction.
Medium Severity
<VulnDiscussion>Any password, no matter how complex, can eventually be cracked. Therefore, passwords need to be changed periodically. If the Aspera system does not limit the lifetime of passwords and force users to change update them, there is a risk passwords could be compromised.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
SRG-NET-000132-ALG-000087
1 Rule
<GroupDescription></GroupDescription>
The IBM Aspera Console must be configured to prohibit or restrict the use of functions, ports, protocols, and/or services, as defined in the PPSM CAL and vulnerability assessments.
Medium Severity
<VulnDiscussion>In order to prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types); organizations must disable or restrict unused or unnecessary physical and logical ports/protocols on information systems. ALGs are capable of providing a wide variety of functions and services. Some of the functions and services provided by default may not be necessary to support essential organizational operations. DoD continually assesses the ports, protocols, and services that can be used for network communications. Some ports, protocols or services have known exploits or security weaknesses. Network traffic using these ports, protocols, and services must be prohibited or restricted in accordance with DoD policy. The ALG is a key network element for preventing these non-compliant ports, protocols, and services from causing harm to DoD information systems. The network ALG must be configured to prevent or restrict the use of prohibited ports, protocols, and services throughout the network by filtering the network traffic and disallowing or redirecting traffic as necessary. Default and updated policy filters from the vendors will disallow older version of protocols and applications and will address most known non-secure ports, protocols, and/or services. However, sources for further policy filters are the IAVMs and the PPSM requirements.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

1 Rule
<GroupDescription></GroupDescription>
The IBM Aspera Console must be configured to use NIST FIPS-validated cryptography to protect the integrity of file transfers.
High Severity
<VulnDiscussion>Without cryptographic integrity protections, information can be altered by unauthorized users without detection. Remote access is access to DoD-nonpublic information systems by an authorized user (or an information system) communicating through an external, non-organization-controlled network. Remote access methods include broadband and wireless connections. Remote access methods include, for example, proxied remote encrypted traffic (e.g., TLS gateways, web content filters, and webmail proxies). Cryptographic mechanisms used for protecting the integrity of information include, for example, signed hash functions using asymmetric cryptography enabling distribution of the public key to verify the hash information while maintaining the confidentiality of the secret key used to generate the hash. This requirement applies to ALGs providing remote access proxy services as part of its intermediary services (e.g., OWA or TLS gateway).

IBM Aspera Faspex must be configured to display the Standard Mandatory DoD-approved Notice and Consent Banner before granting access to the system.
Low Severity
<VulnDiscussion>Display of a standardized and approved use notification before granting access to the network ensures privacy and security notification verbiage used is consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance. System use notifications are required only for access via login interfaces with human users and are not required when such human interfaces do not exist. This requirement applies to network elements that have the concept of a user account and have the login function residing on the network element. The banner must be formatted in accordance with DTM-08-060. Use the following verbiage for network elements that can accommodate banners of 1300 characters: "You are accessing a U.S. Government (USG) Information System (IS) that is provided for USG-authorized use only. By using this IS (which includes any device attached to this IS), you consent to the following conditions: -The USG routinely intercepts and monitors communications on this IS for purposes including, but not limited to, penetration testing, COMSEC monitoring, network operations and defense, personnel misconduct (PM), law enforcement (LE), and counterintelligence (CI) investigations. -At any time, the USG may inspect and seize data stored on this IS. -Communications using, or data stored on, this IS are not private, are subject to routine monitoring, interception, and search, and may be disclosed or used for any USG-authorized purpose. -This IS includes security measures (e.g., authentication and access controls) to protect USG interests--not for your personal benefit or privacy. -Notwithstanding the above, using this IS does not constitute consent to PM, LE or CI investigative searching or monitoring of the content of privileged communications, or work product, related to personal representation or services by attorneys, psychotherapists, or clergy, and their assistants. Such communications and work product are private and confidential. See User Agreement for details." Use the following verbiage for operating systems that have severe limitations on the number of characters that can be displayed in the banner: "I've read & consent to terms in IS user agreem't."

IBM Aspera Shares must implement multifactor authentication for remote access to non-privileged accounts such that one of the factors is provided by a device separate from the system gaining access.
Medium Severity
<VulnDiscussion>For remote access to non-privileged accounts, the purpose of requiring a device that is separate from the information system gaining access for one of the factors during multifactor authentication is to reduce the likelihood of compromising authentication credentials stored on the system. Multifactor solutions that require devices separate from information systems gaining access include, for example, hardware tokens providing time-based or challenge-response authenticators and smart cards such as the U.S. Government Personal Identity Verification card and the DoD common access card. A privileged account is defined as an information system account with authorizations of a privileged user. Remote access is access to DoD-nonpublic information systems by an authorized user (or an information system) communicating through an external, non-organization-controlled network.

<VulnDiscussion>Configuring the network element to implement organization-wide security implementation guides and security checklists ensures compliance with federal standards and establishes a common security baseline across DoD that reflects the most restrictive security posture consistent with operational requirements. Configuration settings are the set of parameters that can be changed that affect the security posture and/or functionality of the network element. Security-related parameters are those parameters impacting the security state of the network element, including the parameters required to satisfy other security control requirements. For the network element, security-related parameters include settings for network traffic management configurations. The askmscli tool sets content-protection secrets only for each user, not for groups and not for all users on a node.

The IBM Aspera High-Speed Transfer Server must limit the number of concurrent sessions to an organization-defined number for all accounts and/or account types.
Medium Severity
<VulnDiscussion>Network element management includes the ability to control the number of users and user sessions that utilize a network element. Limiting the number of current sessions per user is helpful in limiting risks related to DoS attacks. This requirement addresses concurrent sessions for information system accounts and does not address concurrent sessions by single users via multiple system accounts. The maximum number of concurrent sessions must be the same as the requirements specified for the application for which it serves as intermediary. This policy only applies to application gateways/firewalls (e.g., identity management or authentication gateways) that provide user account services as part of the intermediary services. The number of incoming transfer requests to the IBM Aspera High-Speed Transfer Server permitted via a POST to the REST service can be limited by the setting of "transfer_manager_max_concurrent_sessions" in The IBM Aspera.conf.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Medium Severity
<VulnDiscussion>By default, all system users can establish a FASP connection and are only restricted by file permissions. Restrict the user's file operations by assigning them to use aspshell, which permits only the following operations: Running Aspera uploads and downloads to or from this computer. Establishing connections in the application. Browsing, listing, creating, renaming, or deleting contents. To assure accountability and prevent unauthenticated access, organizational users must be identified and authenticated to prevent potential misuse and compromise of the system. Organizational users include organizational employees or individuals the organization deems to have equivalent status of employees (e.g., contractors). Organizational users (and any processes acting on behalf of users) must be uniquely identified and authenticated for all accesses except the following. 1) Accesses explicitly identified and documented by the organization. Organizations document specific user actions that can be performed on the information system without identification or authentication. 2) Accesses that occur through authorized use of group authenticators without individual authentication. Organizations may require unique identification of individuals in group accounts (e.g., shared privilege accounts) or for detailed accountability of individual activity. This requirement applies to ALGs that provide user proxy services, including identification and authentication. This service must use the site's directory service (e.g., Active Directory).

The IBM Aspera High-Speed Transfer Server must restrict users from using transfer services by default.
Medium Severity
<VulnDiscussion>Successful authentication must not automatically give an entity access to an asset or security boundary. The lack of authorization-based access control could result in the immediate compromise and unauthorized access to sensitive information. All DoD systems must be properly configured to incorporate access control methods that do not rely solely on authentication for authorized access. Authorization is the process of determining whether an entity, once authenticated, is permitted to access a specific asset. Information systems use access control policies and enforcement mechanisms to implement this requirement. Authorization procedures and controls must be implemented to ensure each authenticated entity also has a validated and current authorization. Access control policies include identity-based policies, role-based policies, and attribute-based policies. Access enforcement mechanisms include access control lists, access control matrices, and cryptography. ALGs must use these policies and mechanisms to control access on behalf of the application for which it is acting as intermediary. The IBM Aspera High Speed Transfer Server inherently uses file and group ownership of files and directories to support authorization for all supported operating systems. As an additional step and security best practice, ensure all transfers in or out of the authenticated connection are configured to be controlled based on privileges granted to specific users and groups within IBM Aspera configuration.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
