Without a data logging feature, the organization loses an important auditing and analysis tool for event inv | ||||
| SV-256944r902346_rule | APWS-AT-000230 | CCI-001749 | HIGH | All Automation Controller NGINX front-end web server files must be verified for their integrity (e.g., checksums and hashes) before becoming part of the production web server. | Being able to verify that a patch, upgrade, certificate, etc., being added to the web server is unchanged from the producer of the file is essential for file validation and nonrepudiation of the information. The Automation Controller NGINX web server ho | ||||
| SV-256945r903522_rule | APWS-AT-000240 | CCI-001749 | MEDIUM | Expansion modules must be fully reviewed, tested, and signed before they can exist on a production Automation Controller NGINX front-end web server. | In the case of a production web server, areas for content development and testing will not exist, as this type of content is only permissible on a development website. The process of developing on a functional production website entails a degree of trial | ||||
| SV-256946r902352_rule | APWS-AT-000250 | CCI-000381 | MEDIUM | All Automation Controller NGINX front-end web servers must not perform user management for hosted applications. | Web servers require enterprise-wide user management capability in order to prevent unauthorized access, with features like attempt lockouts and password complexity requirements. Unauthorized access to the web server makes the web server and the organizat | ||||

| SV-256952r903524_rule | APWS-AT-000370 | CCI-000382 | MEDIUM | All Automation Controller NGINX web servers must be configured to use a specified IP address and port. | From a security perspective, it is important that all Automation Controller NGINX web servers are configured to use a specified IP address and port because “listening” on all IP addresses poses a vulnerability to the web server. Not confining the web | ||||
| SV-256953r903525_rule | APWS-AT-000400 | CCI-000186 | MEDIUM | Only authenticated system administrators or the designated PKI Sponsor for an Automation Controller NGINX web server must have access to any Automation Controller NGINX web server's private key. | Each Automation Controller NGINX web server's private key is used to prove the identity of the server to clients and securely exchange the shared secret key used to encrypt communications between the Automation Controller NGINX web server and clients.

| SV-256958r903555_rule | APWS-AT-000620 | CCI-001312 | MEDIUM | The Automation Controller NGINX web server must display a default hosted application web page, not a directory listing, when a requested web page cannot be found. | It is important that Automation Controller NGINX web server display a default hosted application web paged and not a directory listing when a requested web page cannot be found, because the web server will be vulnerable to intrusion. For this reason, acce | ||||
| SV-256959r902391_rule | APWS-AT-000640 | CCI-001312 | MEDIUM | Debugging and trace information, within Automation Controller NGINX web server, used to diagnose the web server must be disabled. | It is important that Automation Controller NGINX web server debugging and trace information used to diagnose the web server is disabled, because debugging information can yield information about the Automation Controller NGINX webserver, like web server t | ||||
| SV-256960r903547_rule | APWS-AT-000700 | CCI-001082 | MEDIUM | Nonprivileged accounts on the hosting system must only access Automation Controller NGINX web server security-relevant information and functions through a distinct administrative account. | It is important that Automation Controller NGINX web server security features are separated from nonprivileged users. Special “privileged” roles need to be developed so that only they can have access to those features and administer the web server, wh | ||||
| SV-256961r902397_rule | APWS-AT-000780 | CCI-001813 | MEDIUM | The Automation Controller NGINX web server application, libraries, and configuration files must only be accessible to privileged users. | Automation Controller NGINX web servers can be modified through parameter modification, patch installation, upgrades to the web server or modules, and security parameter changes. With each of these changes, there is the potential for an adverse effect suc | ||||
| SV-256962r903550_rule | APWS-AT-000830 | CCI-002385 | MEDIUM | The Automation Controller NGINX web server must be protected from being stopped by a nonprivileged user. | An attacker has at least two reasons to stop an Automation Controller NGINX web server. The first is to cause a DoS, and the second is to put in place changes the attacker made to an Automation Controller NGINX web server configuration. To prohibit an at | ||||
| SV-256963r902403_rule | APWS-AT-000850 | CCI-002418 | MEDIUM | The Automation Controller NGINX web server must employ cryptographic mechanisms (TLS/DTLS/SSL) to prevent the unauthorized disclosure of information during transmission. | Preventing the disclosure of transmitted information requires that the Automation Controller web server take measures to employ some form of cryptographic mechanism in order to protect the information during transmission. This is usually achieved through | ||||
| SV-256964r903551_rule | APWS-AT-000900 | CCI-002418 | MEDIUM | Automation Controller NGINX web servers must maintain the confidentiality of controlled information during transmission through the use of an approved TLS version. | Transport Layer Security (TLS) is a required transmission protocol for a web server hosting controlled information. The use of TLS provides confidentiality of data in transit between the web server and client. FIPS 140-2 approved TLS versions must be enab | ||||
| SV-256965r902409_rule | APWS-AT-000920 | CCI-002420 | MEDIUM | The Automation Controller NGINX web servers must maintain the confidentiality and integrity of information during preparation for transmission. | Information can be either unintentionally or maliciously disclosed or modified during preparation for transmission, including, for example, during aggregation, at protocol transformation points, and during packing/unpacking. These unauthorized disclosures | ||||
| SV-256966r903536_rule | APWS-AT-000940 | CCI-002605 | MEDIUM | Automation Controller NGINX web servers must install security-relevant software updates within the configured time period directed by an authoritative source (e.g., IAVM, CTOs, DTMs, and STIGs). | Security flaws with software applications are discovered daily.
