Private key data is used to prove that the entity presenting a public key certificate is the certificate's rightful owner. Compromise of private key data allows an adversary to impersonate the key holder. Private key data associated with software certif

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 syst

Off-loading ensures audit information does not get overwritten if the limited audit storage capacity is reached and also protects the audit record in case the system/component being audited is compromised. Off-loading is a common process in information s

Without a real-time alert, security personnel may be unaware of an impending failure of the audit capability and system operation may be adversely affected. Alerts provide organizations with urgent messages. Real-time alerts provide these messages immedi

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

Unrelated or unneeded proxy services increase the attack vector and add excessive complexity to the securing of the ALG. Multiple application proxies can be installed on many ALGs. However, proxy types must be limited to related functions. At a minimum, t

In addition to the reauthentication requirements associated with session locks, organizations may require reauthentication of individuals and/

Organizational users include organizational employees or individuals the orga

User account and privilege validation must be centralized to prevent unauthorized access using changed or revoked privileges. ALGs can implement functions such as traffic filtering, authentication, access, and authorization functions based on computer an

    SV-104243r1_rule SYMP-AG-000370 CCI-000766 MEDIUM Symantec ProxySG providing user authentication intermediary services must use multifactor authentication for network access to nonprivileged accounts. To assure accountability and prevent unauthenticated access, nonprivileged users must use multifactor authentication to prevent potential misuse and compromise of the system. Multifactor authentication uses two or more factors to achieve authentication.
    SV-104245r1_rule SYMP-AG-000380 CCI-001942 MEDIUM Symantec ProxySG providing user authentication intermediary services must implement replay-resistant authentication mechanisms for network access to nonprivileged accounts. A replay attack may enable an unauthorized user to gain access to the application. Authentication sessions between the authenticator and the application validating the user credentials must not be vulnerable to a replay attack. An authentication process
    SV-104247r1_rule SYMP-AG-000390 CCI-002007 MEDIUM Symantec ProxySG must prohibit the use of cached authenticators after 300 seconds at a minimum. If the cached authenticator information is out of date, the validity of the authentication information may be questionable. This requirement applies to all ALGs that may cache user authenticators for use throughout a session. It also applies to ALGs that

Authorization for access to any network element requires an approved and assigned individual account identifier. To ensure only the assigned individual is using the account, the account must be bound to a user certificate when PKI-based authentication is
    SV-104251r1_rule SYMP-AG-000420 CCI-001991 MEDIUM Symantec ProxySG providing user authentication intermediary services using PKI-based user authentication must implement a local cache of revocation data to support path discovery and validation in case of the inability to access revocation information via the network. Without configuring a local cache of revocation data, there is the potential to allow access to users who are no longer authorized (users with revoked certificates). The intent of this requirement is to require support for a secondary certificate validat

Without conforming to FICAM-issued profiles, the information system may not be interoperable with FICAM-authentication protocols, such as SAML 2.0 and OpenID 2.0. Use of FICAM-issued profiles addresses open identity management standards. This only appli

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 terminat

    SV-104265r1_rule SYMP-AG-000490 CCI-001184 HIGH Symantec ProxySG must use Transport Layer Security (TLS) to protect the authenticity of communications sessions. Authenticity protection provides protection against man-in-the-middle attacks/session hijacking and the insertion of false information into sessions. This requirement focuses on communications protection for the application session rather than for the ne

Non-DoD-approved PKIs have not been evaluated to ensure they have security controls and identity vetting procedures in place that are sufficient for DoD systems to rely on the identity asserted in the certificate. PKIs lacking sufficient security controls

Failure to a known safe state helps prevent systems from failing to a state that may cause loss of data or unauthorized access to system resources. Network elements that fail suddenly and with no incorporated failure state planning may leave the hosting s

If the network does not provide safeguards against DoS attacks, network resources will be unavailable to users. Installation of content filtering gateways and application layer firewalls at key boundaries in the architecture mitigates the risk of DoS att

If the network does not provide safeguards against DoS attacks, network resources will be unavailable to users. Load balancing provides service redundancy, which reduces the susceptibility of the ALG to many DoS attacks. The ALG must be configured to pre

DoS attacks can take multiple forms but have the common objective of overloading or blocking a network or host to deny or seriously degrade performance. If the network does not provide safeguards against DoS attack, network resources will be unavailable t
    SV-104277r1_rule SYMP-AG-000550 CCI-002403 MEDIUM Symantec ProxySG must allow incoming communications only from organization-defined authorized sources routed to organization-defined authorized destinations. Unrestricted traffic may contain malicious traffic that poses a threat to an enclave or to other connected networks. Additionally, unrestricted traffic may transit a network, which uses bandwidth and other resources. Access control policies and access co

If a boundary protection device fails in an unsecure manner (open), information external to the boundary protection device may enter, or the device may permit unauthorized information release. Secure failure ensures that when a boundary control device fa

A deny-all, permit-by-exception network communications traffic policy ensures that only connections that are essential and approved are allowed. As a managed interface, the ALG must block all inbound and outbound network communications traffic to the app
    SV-104283r1_rule SYMP-AG-000580 CCI-002400 MEDIUM Symantec ProxySG must identify and log internal users associated with denied outgoing communications traffic posing a threat to external information systems. Without identifying the users who initiated the traffic, it would be difficult to identify those responsible for the denied communications. This requirement applies to network elements that perform Data Leakage Prevention (DLP) (e.g., ALGs, proxies, or a

The required information within error messages will va
