The vCenter PostgreSQL service must encrypt passwords for user authentication. |
The DOD standard for authentication is DOD-approved PKI certificates.
Authentication based on User ID and Password may be used only when it is not possible to employ a PKI certificate and requires AO approval.
In such cases, database passwords stored in clear text, using reversible encryption, or using unsalted hashes... |

Medium |
The vCenter PostgreSQL service must off-load audit data to a separate log management facility. |
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.
The database management system (DBMS) may write audit records to database tables, to files in the file system, to other kinds of local... |

V-259184
|
Medium |
The vCenter PostgreSQL service must log all client disconnections. |
Disconnection may be initiated by the user or forced by the system (as in a timeout) or result from a system or network failure. To the greatest extent possible, all disconnections must be logged.
For completeness of forensic analysis, it is necessary to know how long a user's (or other... |

Medium |
The vCenter PostgreSQL service must log all connection attempts. |
For completeness of forensic analysis, it is necessary to track successful and failed attempts to log on to PostgreSQL. Setting "log_connections" to "on" will cause each attempted connection to the server to be logged, as well as successful completion of client authentication.
Satisfies: SRG-APP-000503-DB-000350, SRG-APP-000503-DB-000351, SRG-APP-000506-DB-000353, SRG-APP-000508-DB-000358 |
|
V-259182
|
Medium |
The vCenter PostgreSQL service must use Coordinated Universal Time (UTC) for log timestamps. |
If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis.
Time stamps generated by PostgreSQL must include date and time. Time is commonly expressed in UTC, a modern continuation of Greenwich Mean Time (GMT), or local time with an... |

V-259181
|
Medium |
The vCenter PostgreSQL service must have log collection enabled. |
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... |

V-259180
|
Medium |
The vCenter PostgreSQL service must provide nonprivileged users with minimal error information. |
Any DBMS or associated application providing too much information in error messages on the screen or printout risks compromising the data and security of the system. The structure and content of error messages need to contain the minimal amount of information.
Databases can inadvertently provide a wealth of information to... |
|
V-259179
|
Medium |
The vCenter PostgreSQL service must write log entries to disk prior to returning operation success or failure. |
Failure to a known secure state helps prevent a loss of confidentiality, integrity, or availability in the event of a failure of the information system or a component of the system. Preserving system state information helps to facilitate system restart and return to the operational mode of the organization with... |
|
V-259175
|
Medium |
The vCenter PostgreSQL service must require authentication on all connections. |
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... |

Medium |
The vCenter PostgreSQL service must be configured to use an authorized port. |
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/services on information systems.
Applications are capable of providing a wide variety of functions and services.... |

V-259173
|
Medium |
The vCenter PostgreSQL service must not load unused database components, software, and database objects. |
Information systems 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 (e.g., key missions, functions).
It is detrimental for software products to provide, or install by default, functionality exceeding requirements... |

V-259172
|
Medium |
The vCenter PostgreSQL service must be configured to protect log files from unauthorized access. |
If audit data were to become compromised, then competent forensic analysis and discovery of the true source of potentially malicious system activity is difficult, if not impossible, to achieve. In addition, access to audit records provides information an attacker could potentially use to his or her advantage.
To ensure the... |

V-259171
|
Medium |
The vCenter PostgreSQL service must produce logs containing sufficient information to establish what type of events occurred. |
Information system auditing capability is critical for accurate forensic analysis. Without establishing what type of event occurred, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.
Audit record content that may be necessary to satisfy the requirement of... |
|
V-259170
|
Medium |
The vCenter PostgreSQL service must initiate session auditing upon startup. |
Session auditing is for use when a user's activities are under investigation. To be sure of capturing all activity during those periods when session auditing is in use, it needs to be in operation for the whole time the database management system (DBMS) is running. |
|
V-259169
|
Medium |
The vCenter PostgreSQL service must generate audit records. |
Under some circumstances, it may be useful to monitor who/what is reading privilege/permission/role information. Therefore, it must be possible to configure auditing to do this. Database management systems (DBMS) typically make such information available through views or functions.
This requirement addresses explicit requests for privilege/permission/role membership information. It does not... |
|
V-259168
|
Medium |
The vCenter PostgreSQL service configuration files must not be accessible by unauthorized users. |
Without the capability to restrict which roles and individuals can select which events are audited, unauthorized personnel may be able to prevent or interfere with the auditing of critical events.
Suppression of auditing could permit an adversary to evade detection.
Misconfigured audits can degrade the system's performance by overwhelming the... |
|
V-259167
|
Medium |
The vCenter PostgreSQL service must enable "pgaudit" to provide audit record generation capabilities. |
Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.
Audit records can be generated from various components within the database management system (DBMS) (e.g., process, module). Certain specific application functionalities may... |
|
V-259166
|
Medium |
The vCenter PostgreSQL service must limit the number of concurrent sessions. |
Database management includes the ability to control the number of users and user sessions utilizing a database management system (DBMS). Unlimited concurrent connections to the DBMS could allow a successful denial-of-service (DoS) attack by exhausting connection resources, and a system can also fail or be degraded by an overload of... |
