Resource exhaustion can occur when an unlimited number of concurrent requests are allowed on a web site, facilitating a denial of service attack. Mitigating this kind of attack will include limiting the parameter values associated with keepalive, (i.e., a parameter used to limit the amount of time a connection may be inactive). HAProxy provides an http-request timeout parameter that set the maximum allowed time to wait for a complete HTTP request. Setting this parameter will mitigate slowloris DoS attacks. Slowloris tries to keep many connections to the target web server open and hold them open as long as possible. It accomplishes this by opening connections to the target web server and sending a partial request. Periodically, it will send subsequent HTTP headers, adding to—but never completing—the request.
Checks: C-43272r665284_chk

At the command prompt, execute the following command: grep 'timeout http-request' /etc/haproxy/haproxy.cfg If the value of ''timeout http-request" is not set to "5000", is commented out, or is missing, this is a finding.

Session management is the practice of protecting the bulk of the user authorization and identity information. As a load balancer, HAProxy must participate in session management in order to set the session management cookie. Additionally, HAProxy must also ensure that the backend server which started the session with the client is forwarded subsequent requests from the client.

Transport Layer Security (TLS) is optional for a public web server. However, if authentication is being performed, then the use of the TLS protocol is required. Without the use of TLS, the authentication data would be transmitted unencrypted and would become vulnerable to disclosure. Using TLS along with DoD PKI certificates for encryption of the authentication data protects the information from being accessed by all parties on the network. To further protect the authentication data, the web server must use a FIPS 140-2 approved TLS version and all non-FIPS-approved SSL versions must be disabled. FIPS 140-2 approved TLS versions include TLS V1.0 or greater. NIST SP 800-52 specifies the preferred configurations for government systems.

Data exchanged between the user and the web server can range from static display data to credentials used to log into the hosted application. Even when data appears to be static, the non-displayed logic in a web page may expose business logic or trusted system relationships. The integrity of all the data being exchanged between the user and web server must always be trusted. To protect the integrity and trust, encryption methods should be used to protect the complete communication session. In order to protect the integrity and confidentiality of the remote sessions, HAProxy uses SSL/TLS.

Remote access to the web server is any access that communicates through an external, non-organization-controlled network. Remote access can be used to access hosted applications or to perform management functions. By providing remote access information to an external monitoring system, the organization can monitor for cyber attacks and monitor compliance with remote access policies. The organization can also look at data organization wide and determine an attack or anomaly is occurring on the organization which might not be noticed if the data were kept local to the web server.

An accurate and current audit trail is essential for maintaining a record of system activity. If the logging system fails, the SA must be notified and must take prompt action to correct the problem. Minimally, the system must log this event and the SA will receive this notification during the daily system log review. If feasible, active alerting (such as e-mail or paging) should be employed consistent with the site's established operations management systems and procedures.
Checks: C-43284r665320_chk

Interview the ISSO. Determine if logging failure events are monitored, and warnings provided to the ISSO. If logging failure events do not provide warnings in accordance with organization policies, this is a finding. If alerts are not sent or the web server is not configured to use a dedicated logging tool that meets this requirement, this is a finding.

The DoD standard for authentication is DoD-approved PKI certificates. A certificate’s certification path is the path from the end entity certificate to a trusted root certification authority (CA). Certification path validation is necessary for a relying party to make an informed decision regarding acceptance of an end entity certificate. Certification path validation includes checks such as certificate issuer trust, time validity and revocation status for each certificate in the certification path. Revocation status information for CA and subject certificates in a certification path is commonly provided via certificate revocation lists (CRLs) or online certificate status protocol (OCSP) responses.

Failure in a known state can address safety or security in accordance with the mission/business needs of the organization. Failure in 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. Failure in a known safe state helps prevent systems from failing to a state that may cause loss of data or unauthorized access to system resources. Applications or systems that fail suddenly and with no incorporated failure state planning may leave the hosting system available but with a reduced security protection capability. Preserving information system state information also facilitates system restart and return to the operational mode of the organization with less disruption of mission/business processes. An example is a firewall that blocks all traffic rather than allowing all traffic when a firewall component fails. This prevents an attacker from forcing a failure of the system in order to obtain access. Web servers must fail to a known consistent state. Validating the server's configuration file during start and restart events can help to minimize the risk of an unexpected server failure during system start.

Information needed by an attacker to begin looking for possible vulnerabilities in a web server includes any information about the web server and plug-ins or modules being used. When debugging or trace information is enabled in a production web server, information about the web server, such as web server type, version, patches installed, plug-ins and modules installed, type of code being used by the hosted application, and any backends being used for data storage may be displayed. Since this information may be placed in logs and general messages during normal operation of the web server, an attacker does not need to cause an error condition to gain this information.

Leaving sessions open indefinitely is a major security risk. An attacker can easily use an already authenticated session to access the hosted application as the previously authenticated user. By closing sessions after an absolute period of time, the user is forced to re-authenticate guaranteeing the session is still in use. Enabling an absolute timeout for sessions closes sessions that are still active. Examples would be a runaway process accessing the web server or an attacker using a hijacked session to slowly probe the web server. HAProxy provides a 'tune.ssl.lifetime' parameter, which will set an absolute timeout on SSL sessions.

Leaving sessions open indefinitely is a major security risk. An attacker can easily use an already authenticated session to access the hosted application as the previously authenticated user. By closing sessions after a set period of inactivity, the web server can make certain that those sessions that are not closed through the user logging out of an application are eventually closed. Acceptable values are "5" minutes for high-value applications, "10" minutes for medium-value applications, and "20" minutes for low-value applications. HAProxy provides an appsession parameter, which will invalidate an inactive cookie after a configurable amount of time.

Remote access to the web server is any access that communicates through an external, non-organization-controlled network. Remote access can be used to access hosted applications or to perform management functions. A web server can be accessed remotely and must be capable of restricting access from what the DoD defines as nonsecure zones. Nonsecure zones are defined as any IP, subnet, or region that is defined as a threat to the organization. The nonsecure zones must be defined for public web servers logically located in a DMZ, as well as private web servers with perimeter protection devices. By restricting access from nonsecure zones, through internal web server access list, the web server can stop or slow denial of service (DoS) attacks on the web server. As the web server for the vRA Virtual Appliance Management Interface (vAMI), Lighttpd is the primary remote access management system for vRA. Lighttpd must be configured to restrict inbound connections from nonsecure zones. To accomplish this, the SSL engine must be enabled. The SSL engine forces Lighttpd to only listen via secure protocols.

There are many aspects of appropriate web server logging for security. Storage capacity must be adequate. ISSO and SA must receive warnings and alerts when storage capacity is filled to 75%. Writing events to a centralized management audit system offers many benefits to the enterprise over having dispersed logs. Centralized management of audit records and logs provides for efficiency in maintenance and management of records, enterprise analysis of events, and backup and archiving of event records enterprise-wide. The web server and related components are required to be capable of writing logs to centralized audit log servers. This requirement can be met by configuring the web server to utilize a dedicated log tool that meets this requirement.

A web server will typically utilize logging mechanisms for maintaining a historical log of activity that occurs within a hosted application. This information can then be used for diagnostic purposes, forensics purposes, or other purposes relevant to ensuring the availability and integrity of the hosted application. While it is important to log events identified as being critical and relevant to security, it is equally important to notify the appropriate personnel in a timely manner so they are able to respond to events as they occur. Manual review of the web server logs may not occur in a timely manner, and each event logged is open to interpretation by a reviewer. By integrating the web server into an overall or organization-wide log review, a larger picture of events can be viewed, and analysis can be done in a timely and reliable manner.

Transport Layer Security (TLS) is optional for a public web server. However, if authentication is being performed, then the use of the TLS protocol is required. Without the use of TLS, the authentication data would be transmitted unencrypted and would become vulnerable to disclosure. Using TLS along with DoD PKI certificates for encryption of the authentication data protects the information from being accessed by all parties on the network. To further protect the authentication data, the web server must use a FIPS 140-2 approved TLS version and all non-FIPS-approved SSL versions must be disabled. FIPS 140-2 approved TLS versions include TLS V1.0 or greater. NIST SP 800-52 specifies the preferred configurations for government systems.

Data exchanged between the user and the web server can range from static display data to credentials used to log into the hosted application. Even when data appears to be static, the non-displayed logic in a web page may expose business logic or trusted system relationships. The integrity of all the data being exchanged between the user and web server must always be trusted. To protect the integrity and trust, encryption methods should be used to protect the complete communication session. In order to protect the integrity and confidentiality of the remote sessions, HAProxy uses SSL/TLS.

The HTTP protocol is a stateless protocol. To maintain a session, a session identifier is used. The session identifier is a piece of data that is used to identify a session and a user. If the session identifier is compromised by an attacker, the session can be hijacked. By encrypting the session identifier, the identifier becomes more difficult for an attacker to hijack, decrypt, and use before the session has expired. In order to protect the integrity and confidentiality of the remote sessions, HAProxy uses SSL/TLS.

During the initial setup of a Transport Layer Security (TLS) connection to the web server, the client sends a list of supported cipher suites in order of preference. The web server will reply with the cipher suite it will use for communication from the client list. If an attacker can intercept the submission of cipher suites to the web server and place, as the preferred cipher suite, a weak export suite, the encryption used for the session becomes easy for the attacker to break, often within minutes to hours.

Limiting the total number of connections that a server is allowed to open prevents an attacker from overloading a web server. Overloading the server will prevent it from managing other tasks besides serving web requests. This setting works together with per-client limits to mitigate against DDoS attacks.

Security flaws with software applications are discovered daily. Vendors are constantly updating and patching their products to address newly discovered security vulnerabilities. Organizations (including any contractor to the organization) are required to promptly install security-relevant software updates (e.g., patches, service packs, and hot fixes). Flaws discovered during security assessments, continuous monitoring, incident response activities, or information system error handling must also be addressed expeditiously. Organization-defined time periods for updating security-relevant software may vary based on a variety of factors including, for example, the security category of the information system or the criticality of the update (i.e., severity of the vulnerability related to the discovered flaw). This requirement will apply to software patch management solutions used to install patches across the enclave and to applications themselves that are not part of that patch management solution. For example, many browsers today provide the capability to install their own patch software. Patch criticality, as well as system criticality will vary. Therefore, the tactical situations regarding the patch management process will also vary. This means that the time period used must be a configurable parameter. Time frames for application of security-relevant software updates may be dependent upon the Information Assurance Vulnerability Management (IAVM) process. The application will be configured to check for and install security-relevant software updates within an identified time period from the availability of the update. The specific time period will be defined by an authoritative source (e.g., IAVM, CTOs, DTMs, and STIGs).
