CA API Gateway ALG Security Technical Implementation Guide
Rules, Groups, and Values defined within the XCCDF Benchmark
-
The CA API Gateway must 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 pro...Rule Medium Severity -
The CA API Gateway providing content filtering must integrate with an ICAP-enabled Intrusion Detection System that updates malicious code protection mechanisms and signature definitions whenever new releases are available in accordance with organizational configuration management policy and procedures.
Malicious code protection mechanisms include, but are not limited to, antivirus and malware detection software. In order to minimize any potential negative impact to the organization caused by mali...Rule Medium Severity -
The CA API Gateway providing content filtering must be configured to perform real-time scans of files from external sources at network entry/exit points as they are downloaded and prior to being opened or executed.
Malicious code includes viruses, worms, trojan horses, and spyware. The code provides the ability for a malicious user to read from and write to files and folders on a computer's hard drive. Malici...Rule Medium Severity -
The CA API Gateway providing content filtering must send an immediate (within seconds) alert to the system administrator, at a minimum, in response to malicious code detection.
Without an alert, security personnel may be unaware of an impending failure of the audit capability, which will impede the ability to perform forensic analysis and detect rate-based and other anoma...Rule Medium Severity -
The CA API Gateway providing content filtering must block or restrict detected prohibited mobile code.
Mobile code is defined as software modules obtained from remote systems, transferred across a network, and then downloaded and executed on a local system without explicit installation or execution ...Rule Medium Severity -
The CA API Gateway providing content filtering must prevent the download of prohibited mobile code.
Mobile code is defined as software modules obtained from remote systems, transferred across a network, and then downloaded and executed on a local system without explicit installation or execution ...Rule Medium Severity -
To protect against data mining, the CA API Gateway providing content filtering must prevent SQL injection attacks launched against data storage objects, including, at a minimum, databases, database records, and database fields.
Data mining is the analysis of large quantities of data to discover patterns and is used in intelligence gathering. Failure to prevent attacks launched against organizational information from unaut...Rule Medium Severity -
To protect against data mining, the CA API Gateway providing content filtering must detect SQL injection attacks launched against data storage objects, including, at a minimum, databases, database records, and database fields.
Data mining is the analysis of large quantities of data to discover patterns and is used in intelligence gathering. Failure to detect attacks launched against organizational databases may result in...Rule Medium Severity -
The CA API Gateway must off-load audit records onto a centralized log server.
Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading is a common process in information systems with limited audit storage capacity. Th...Rule Medium Severity -
The CA API Gateway providing user authentication intermediary services 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.
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 ...Rule Medium Severity -
The CA API Gateway must prohibit the use of cached authenticators after an organization-defined time period.
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 ...Rule Medium Severity -
The CA API Gateway providing user authentication intermediary services must conform to Federal Identity, Credential, and Access Management (FICAM) issued profiles.
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 addr...Rule Medium Severity -
The CA API Gateway must only allow incoming communications 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 a...Rule Medium Severity -
The CA API Gateway providing content filtering must be configured to integrate with a system-wide intrusion detection system.
Without coordinated reporting between separate devices, it is not possible to identify the true scale and possible target of an attack. Integration of the ALG with a system-wide intrusion detectio...Rule Medium Severity -
The CA API Gateway providing content filtering must generate a notification on the console when root-level intrusion events that attempt to provide unauthorized privileged access are detected.
Without an alert, security personnel may be unaware of major detection incidents that require immediate action, and this delay may result in the loss or compromise of information. The ALG generate...Rule Medium Severity -
The CA API Gateway providing content filtering must generate an alert to, at a minimum, the ISSO and ISSM when Denial of Service (DoS) incidents are detected.
Without an alert, security personnel may be unaware of major detection incidents that require immediate action, and this delay may result in the loss or compromise of information. The ALG generate...Rule Low Severity -
The CA API Gateway providing user authentication intermediary services must transmit only encrypted representations of passwords.
Passwords need to be protected at all times, and encryption is the standard method for protecting passwords. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily c...Rule Medium Severity -
The CA API Gateway providing user access control intermediary services must generate audit records showing starting and ending time for user access to the system.
Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an in...Rule Medium Severity -
The CA API Gateway providing encryption intermediary services must implement NIST FIPS-validated cryptography for digital signatures.
Use of weak or untested encryption algorithms undermines the purposes of using encryption to protect data. The network element must implement cryptographic modules adhering to the higher standards ...Rule Medium Severity -
The CA API Gateway that provides intermediary services for HTTP must inspect inbound and outbound HTTP traffic for protocol compliance and protocol anomalies.
Application protocol anomaly detection examines application layer protocols such as HTTP to identify attacks based on observed deviations in the normal RFC behavior of a protocol or service. This t...Rule Medium Severity

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
