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, Lighttpd uses SSL/TLS.

Ascertaining the correct type of event that occurred is important during forensic analysis. The correct determination of the event and when it occurred is important in relation to other events that happened at that same time. Without sufficient information establishing what type of log event occurred, investigation into the cause of event is severely hindered. Log record content that may be necessary to satisfy the requirement of this control includes, but is not limited to, time stamps, source and destination IP addresses, user/process identifiers, event descriptions, application-specific events, success/fail indications, file names involved, access control, or flow control rules invoked. Lighttpd logs user activity in the access.log file using the Common Log Format (CLF). The CLF format, a World Wide Web Consortium standard, captures logs all user session information related to the hosted application session. This will enable forensic analysis of server events in case of malicious event.

Ascertaining the correct order of the events that occurred is important during forensic analysis. Events that appear harmless by themselves might be flagged as a potential threat when properly viewed in sequence. By also establishing the event date and time, an event can be properly viewed with an enterprise tool to fully see a possible threat in its entirety. Without sufficient information establishing when the log event occurred, investigation into the cause of event is severely hindered.

Ascertaining the correct location or process within the web server where the events occurred is important during forensic analysis. Correctly determining the web service, plug-in, or module will add information to the overall reconstruction of the logged event. For example, an event that occurred during communication to a cgi module might be handled differently than an event that occurred during a communication session to a user. Without sufficient information establishing where the log event occurred within the web server, investigation into the cause of event is severely hindered.

Log data is essential in the investigation of events. If log data were to become compromised, then competent forensic analysis and discovery of the true source of potentially malicious system activity would be difficult, if not impossible, to achieve. In addition, access to log records provides information an attacker could potentially use to their advantage since each event record might contain communication ports, protocols, services, trust relationships, user names, etc. Lighttpd creates its own logs. It does not use an external log system. The Lighttpd log must be protected from unauthorized deletion.

Allowing this functionality, development, and deployment is much easier for web authors. WebDAV is not widely used and has serious security concerns because it may allow clients to modify unauthorized files on the web server.

When it comes to DoS attacks, most of the attention is paid to ensuring that systems and applications are not victims of these attacks. While it is true that those accountable for systems want to ensure they are not affected by a DoS attack, they also need to ensure their systems and applications are not used to launch such an attack against others. To that extent, a variety of technologies exist to limit, or in some cases, eliminate the effects of DoS attacks. Limiting system resources that are allocated to any user to a bare minimum may also reduce the ability of users to launch some DoS attacks. Applications and application developers must take the steps needed to ensure users cannot use these applications to launch DoS attacks against other systems and networks.

In UNIX and related computer operating systems, a file descriptor is an indicator used to access a file or other input/output resource, such as a pipe or network connection. File descriptors index into a per-process file descriptor table maintained by the kernel, that in turn indexes into a system-wide table of files opened by all processes, called the file table. As a single-threaded server, Lighttpd must be limited in the number of file descriptors that can be allocated. This will prevent Lighttpd from being used in a form of DoS attack against the Operating System.

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.

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.

It is critical for the appropriate personnel to be aware if a system is at risk of failing to process logs as required. Log processing failures include: software/hardware errors, failures in the log capturing mechanisms, and log storage capacity being reached or exceeded. If log capacity were to be exceeded, then events subsequently occurring would not be recorded. Organizations shall define a maximum allowable percentage of storage capacity serving as an alarming threshold (e.g., web server has exceeded 75% of log storage capacity allocated), at which time the web server or the logging mechanism the web server utilizes will provide a warning to the ISSO and SA at a minimum. This requirement can be met by configuring the web server to utilize a dedicated log tool that meets this requirement.

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.

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 enabled and non-FIPS-approved SSL versions must be disabled. NIST SP 800-52 defines the approved TLS versions for government applications. SSL/TLS is a collection of protocols. Weaknesses have been identified with earlier SSL protocols, including SSLv2 and SSLv3, hence SSL versions 1, 2, and 3 should no longer be used. The best practice for transport layer protection is to only provide support for the TLS protocols - TLS 1.0, TLS 1.1 and TLS 1.2. This configuration will provide maximum protection against skilled and determined attackers and is appropriate for applications handling sensitive data or performing critical operations. Lighttpd must explicitly disable all of the SSL-series protocols. If these protocols are not disabled, the vRA appliance may be vulnerable to a loss of confidentiality.

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 Lighttpd 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.

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.

IP forwarding permits Lighttpd to forward packets from one network interface to another. The ability to forward packets between two networks is only appropriate for systems acting as routers. Lighttpd is not implemented as a router. With the url.redirect configuration parameter, Lighttpd can be configured to forward IPv4 packets. This configuration parameter is prohibited, unless Lighttpd is redirecting packets to localhost, 127.0.0.1.

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).
