The CSIRT should anticipate that potential information security incidents may be reported from various sources in various formats, both manually and automatically. To enable constituents to report information security incidents more effectively, the CSIRT should provide one or more mechanisms as well as guidance or instructions on what and how to securely report information security incidents. Reporting mechanisms can include email, a website, a dedicated information security incident reporting form or portal, or other appropriate methods to enable reports to be submitted safely and securely. Reporting guidance, if not included as part of an information security incidents reporting form itself, should be provided in separate documentation or via a webpage, and should list the specific information that is desirable for inclusion in the report. Due to the potentially large number of automatically escalated potential information security incidents detected via an Information Security Event Management service, this must be planned for in advance of adopting such interfaces or authorizing constituents to use them.",

This applies to any formats and sources: hardware, firmware, memory, software, etc. Any artefact or evidence must be preserved and collected without any modification, and kept in isolation. As some artefacts and data may become evidence in the context of law enforcement activities, specific regulations or requirements may apply. Even without preserving a chain-of-custody, this service usually involves complex and time-consuming tasks, and requires expertise, setting up dedicated and monitored analysis environments--with or without external accesses from standard wired or wireless networks (such as performing the forensics activities in a sealed or Faraday room), logging of activities, and compliance with procedures. As part of the handling of information security incidents, digital artefacts may be found on affected systems or malware distribution sites. Artefacts may be the remnants of an intruder attack, such as executables, scripts, files, images, configuration files, tools, tool outputs, logs, live or dormant pieces of code, etc. The analysis is carried out in order to find out some or all of the information listed below, which is not considered to be a complete list: The context required of the artefact to run and to perform its intended tasks, whether malicious or not\nHow the artefacts may have been utilized for the attack: uploaded, downloaded, copied, executed, or created within an organization’s environments or components\nWhich systems have been involved locally and remotely to support the distribution and actions\nWhat an intruder did once to access to the system, network, organization, or infrastructure was established: from passively collecting data, to actively scanning and transmitting data for exfiltration purposes, or collecting new action requests, updating itself or making a lateral movement inside a compromised (local) network\nWhat a user, user process, or user system did once the user account or user device was compromised\nWhat behavior characterizes the artefacts or compromised systems, either in standalone mode, in conjunction with artefacts or components, connected to a local network or the Internet, or in any combination\nHow the artefacts or compromised systems establish connectivity with the target (e.g., intrusion path, initial target, or detection evasion techniques);\nWhat communication architecture (peer-to-peer, command-and-control, both) has been utilized\nWhat were the actions of the threat actors, what is their network and systems footprint\nHow the intruders or artefacts evaded detection (even over long periods of time which may include reboot or reinitialization) This can be achieved through various types of activities including media or surface analysis\nreverse engineering\nruntime or dynamic analysis\ncomparative analysis Each activity provides additional information about the artefacts. Analysis methods include but are not limited to identification of type and characteristics of artefacts, comparison with known artefacts, observation of artefact execution in a runtime or a live environment, and disassembling and interpreting binary artefacts. In carrying out an analysis of the artefacts, an analyst attempts to reconstruct and determine what the intruder did, in order to detect the exploited vulnerability, assess damages, develop solutions to mitigate against the artefacts, and provide information to constituents and other researchers.",

While systems are compromised or malware is active on end user systems, further data losses and more compromises occur. It is usually the main objective of attacks to reach out to specific data and systems, including attacks (including but not limited to lateral movements) to other organizations both inside and outside the organization suffering from the information security incident. Stopping or at least limiting the extent of any malicious activities or further losses requires short-term actions such as blocking or filtering traffic and removing access to specific services or systems, and can also result in the disconnection of critical systems. Denying further access to potentially critical evidence data will allow a full analysis of such evidence. Denying further access to other systems and networks will also limit the exposure from liability as a result of damage done to other organizations. Stopping immediate damage and limiting the extent of malicious activity through short-term tactical actions (for example, blocking or filtering traffic) can also involve regaining control of systems. As long as attackers or active malware have ready access to more systems or networks, no return to normal operation will be possible.",
