NEESComm Cybersecurity Plan (version 2.10) Download a copy – NEESComm_Cybersecurity_Plan_v2_1.pdf (280 Kb, uploaded by Richard B White 3 years 5 months ago)


The NEES Cyberinfrastructure (CI) system is composed of fourteen equipment sites and one central IT facility, henceforth referred to as NEEScomm IT. With IT resources (hardware and software) spread across the system and connected together with internet protocols over the public internet, computer security is of prime concern. As a leading Cyberinfrastructure project, NEES has developed a comprehensive cybersecurity approach that includes best practice cybersecurity policies and mechanisms at NEESCentral and an annual security audit at each of the NEES sites.

The purpose of the NEEScomm CyberSecurity Plan (CSP) is to:

  • Delineate responsibilities, roles and expected behavior of all individuals who access NEEScomm IT services.
  • Provide an overview of the security requirements for NEES machines at the sites.
  • Identify a strategy for responding to security incidents.

The security plan should be viewed as documentation describing the structured process to plan adequate, cost-effective security protection for NEES CI. As a result, this document provides a list of standards, guidelines and procedures for the implementation of the NEEScomm CSP. It is recommended that the security plan be reviewed and updated annually to reflect enhancements to the NEEScomm IT services, the assets at the sites, and to react to new security threats from the ever-changing computer security field.

The target audience for this document is the entire NEES community. This audience includes NEEScomm IT members, NEES IT members at each site, and researchers and practitioners in earthquake engineering who make decisions involving or make use of NEES information technology systems.

The current document builds on several sources, including the last available NEES cybersecurity policy document 2. However, the document is outdated (it dates back to 2005). Much of the policy was never put in practice and many of the IT resources and practices have changed since then. This current document is therefore significantly different from this previous document.

Roles and Responsibilities

NEES CI security is the responsibility of everyone who can affect the security of NEES CI systems. However, since the specific duties and responsibilities of various individuals and organizational entities vary considerably, certain key responsibilities should be made explicit for the sake of clear accountability.

Senior Management

Ultimately, overall responsibility for the success of the NEES CI system lies with the senior management team comprising the NEEScomm IT Director and the NEEScomm Center Director. This management team will be assisted by the NEEScomm Cybersecurity Officer (CSO) in the matter of the cybersecurity program and its overall goals, objectives, and priorities in order to support the overall mission of NEES. The senior management team is also responsible for ensuring that adequate resources are applied to the security program to ensure its success.

Cyberinfrastructure Security Management

The NEES CSO (currently identified as Saurabh Bagchi at NEEScomm) in collaboration with the NEES IT director directs NEEScomm’s day-to-day management of its security program, including maintaining a security website with policies and guidelines, providing security advice to the NEES community, and conducting regular security audits. This person is also responsible for coordinating all security related interactions among the various participating organizations of NEES.

Site IT Managers

To ensure that proper security measures are taken at each equipment site, site security should ultimately be the responsibility of both the NEES equipment site Principal Investigator and the Site IT Managers who are responsible for the day-to-day operations of the NEES equipment sites, including the supporting computer systems. Arguably the most important cybersecurity practice the Site IT Managers can follow is to patch the installed software base promptly. We have found in our security audits (described in Section 6.0) that the overwhelming majority of vulnerabilities arise from patches not having been installed in the deployed software, even though the patches had been publicly available. Prompt patching is understandably a complex task due to several reasons – the patch may bring out an incompatibility in the software and break the installation, the vendor may not have adequately automated the process and the Site IT Manager may need to do tedious work to put this in place, and the frequency of patch releases may overwhelm some. Despite these challenges, we believe it is well worth the effort to promptly patch the deployed software base. Most vendors have news feeds or notifications that one can subscribe to and this helps with getting a prompt news of the patch. Other responsibilities include enforcing appropriate security controls such as management, operational, and technical controls that comply with NEEScomm’s CSP. It is the Site IT Managers who are ultimately responsible for the security of a site’s IT systems. They are responsible for implementing technical security on computer systems and for being familiar with security technology that relates to their systems. They also are required to ensure the continued operation of their IT services to meet the needs of NEES researchers, as well as analyze technical vulnerabilities in their systems and their security implications.

Authentication and Authorization Policy

Controlled access to IT resources is essential for NEEScomm to fulfill its mission. This policy describes our plan for Authentication and Authorization that can support current needs for electronic access and accommodate future services and technologies by employing standardized mechanisms for Identification, Authentication, and Authorization.


This policy is guided by the following objectives:

  1. To ensure that NEEScomm can, without limitation, operate and maintain its IT resources;
  2. To ensure that NEEScomm can, without limitation, protect the security and functionality of its IT resources and the data stored on those resources;
  3. To protect NEEScomm’s other property, rights, and resources;
  4. To preserve the integrity and reputation of NEEScomm;
  5. To safeguard the privacy, property, rights, and data of users of NEEShub;
  6. To comply with applicable existing NSF regulations; and
  7. To comply with existing Purdue University Henceforth, whenever just University is mentioned without any qualification, it will mean Purdue University. policies 1, standards, guidelines, and procedures.

Policy Statement

Access Control

Identification, Authentication, and Authorization are controls that facilitate access to and protect NEEScomm IT resources and data. Access to non-public IT resources will be achieved by unique User Credentials and will require Authentication.

NEEScomm will assign a username and password for Identification and Authentication purposes to each individual that has a business, research, or educational need to access NEEScomm IT resources. In all cases, only the minimum privileges necessary to complete required tasks are assigned to that individual. Privileges assigned to each individual will be reviewed on a periodic basis and modified or revoked upon a change in status within the NEES community.

All NEEScomm IT resources must use only encrypted Authentication and Authorization mechanisms unless otherwise authorized by the CSO.

User Credentials Standard

In general NEEScomm will maintain open operations in that it will allow users from different sectors, academic and industrial, and from all different geographies, to be registered users on NEEShub. The minimum requirement we will mandate at the time of account creation is that the user have a valid email account. However, NEEScomm CSO maintains the right to block any account creation request if the CSO suspects that the account is being created for malicious purposes, such as, but not limited to, automated creation of accounts, use of NEEScomm CI resources for launching attacks, and affecting other legitimate users. The CSO also reserves the right to request for further information prior to approving the request for account creation, including, but not limited to, reference material from a university administration, reason for request for account creation, prior evidence of participation in the earthquake engineering or IT or education-outreach-training (EOT) communities. If an account creation request is denied, the entire chain of actions leading to the denial will be documented and will be made available to NSF upon request.

User Credentials Standard

The password will be used as the primary user credential, to be used along with the username. A password may be used only by the authorized user. Passwords or accounts should never be shared with anyone, including trusted friends or family members. Account owners will be held responsible for any actions performed using their accounts. NEES IT staff will never ask users to disclose their passwords in any manner. Passwords should never be written down and left in plain sight, or stored in plain text online.

Passwords for NEEScomm IT resources must comply with the following standards:

  • Passwords must contain at least 1 letter.
  • Passwords must contain at least 1 number or punctuation mark.
  • Passwords must be at least 8 characters long.
  • Passwords must contain more than 4 unique characters.
  • Passwords must not contain easily guessed words (e.g. Purdue, nees, boiler).
  • Passwords must not contain your name or your username.
  • New passwords must be different than the previous password (re-use of the same password will not be allowed for one (1) year).

The use of group accounts for administrative purposes and shared passwords for those accounts should be minimized where technically feasible. In situations where group accounts for administrative purposes and shared passwords for those accounts is required (e.g. “Root” or “Administrator” accounts), the passwords used must also follow the standards stated above.

Password Expiration

All NEEScomm IT resource passwords must be changed at least every one hundred twenty (120) days. Any group password must be changed every one hundred twenty (120) days and immediately upon any personnel change within the group.

Two-Factor Authentication

Two-factor authentication (TFA) offers inherently greater security than reusable passwords. TFA utilizes a “something you have and something you know” method of authenticating users. The “something you have” is a hardware device such as a token or smart card, and the “something you know” is a PIN (personal identification number, or alphanumeric code). The combination of the hardware device and the PIN authenticates users to systems. NEEScomm IT will be using RSASecurID  fobs selectively for controlling access to critical IT assets. What constitutes critical IT assets is an operational decision that will be made by the NEEScomm IT Director and the CSO as and when the situational need arises.

In addition, TFA devices of all kinds (tokens, smart cards, etc.) should be safeguarded and kept with the user at all times. If the TFA device has been lost or stolen, this should be reported to the NEEScomm CSO immediately.

Privacy Policy

The right to privacy is a deeply held conviction, especially within intellectual and academic communities. Privacy is critical to the intellectual freedom that forms the foundation of higher education. While the right to individual privacy is highly valued in the University community, it must, however, be balanced with legal obligations and the larger needs of the community.

Although NEEScomm seeks to create, maintain, and protect the privacy of electronic information on its IT resources, users should be aware that the use of NEEScomm IT resources is not completely private. Accordingly, users of NEEScomm IT resources are hereby specifically notified that they have no expectation of privacy in connection with their use of such IT resources. Except as provided in this policy, NEEScomm does not routinely monitor the content of communications or transmissions using IT resources. The normal operation and maintenance of the NEEScomm IT resources require the back up and caching of data and communications, the logging of activity, the monitoring of general usage patterns, and other such activities. There are also special circumstances such as illness; death; violation of NEEScomm policies, regulations procedures or rules; or illegal activity which may warrant intrusive or restrictive action within an individual’s computer account and/or devices.


The purpose of this policy is to outline the special circumstances under which NEEScomm may access content or electronically stored wire and electronic communications and information on its IT resources in order to protect its legitimate operational and strategic interests. Those interests include NEEScomm’s need to ensure that it can, without limitation, operate and maintain its IT resources as well as protect the integrity, security, or functionality of data stored on NEEScomm IT; protect NEEScomm’s other property, rights, and resources; ensure compliance with University policies, procedures, or regulations; preserve the integrity and reputation of the University; safeguard the property, rights, and data of third parties; and comply with applicable laws.

Policy Statement

This policy covers the following types of information:

  1. Data and computer accounts on NEEScomm systems or other NEEScomm-owned devices.
  2. Voice and data telecommunications traffic to, from, or between IT resources, including without limitation any of the devices listed above.

In general, the types of information enumerated above are considered private and cannot be accessed by someone other than the person to whom the IT resource account has been assigned, the person from whom the information originated, or the person to whom the device has been assigned. According to the separate data sharing and archiving policy, project data must be uploaded to NEEScomm Data Repository and made public after a certain length of time. Furthermore, as noted above, NEEScomm does not routinely monitor the content of communications or transmissions using IT resources. NEEScomm does, however, specifically reserve the right, with or without notice, to intercept, access, monitor, inspect, copy, store, use, or disclose the contents of communications or transmissions employing IT resources when it reasonably believes these actions are appropriate in order to protect its interests.

More specifically, and without limiting the foregoing general rights, NEEScomm reserves the right to monitor and inspect computer accounts and devices as warranted by the need to protect the information and services held on NEEScomm IT resources and any legal obligations that arise, and NEEScomm may, without notice, use: (a) security tools designed to locate security flaws in equipment connected to IT resources; (b) network monitoring hardware and software that capture the contents of packets traversing the network; © network hardware and software designed to protect IT resources and users of IT resources, including without limitation Anti-Phishing Services, Anti-Virus Services, Intrusion Detection Systems, Spam Filtering Services, and Anti-Spyware Services; or (d) system log information, including without limitation source and destination for a connection, session start and end times, login name, timestamps, and commands issued. In addition, and again without limiting the above-enumerated general right to act when it reasonably believes these actions are appropriate in order to protect its interests, NEEScomm may, acting through NEEScomm-authorized technicians and administrators and pursuant to the procedures specified herein, access or permit access to the contents of communications or electronically stored wire and electronic communications and information employing IT resources if it:

  • Has a reasonable belief that a process active in the account or device is causing or may cause significant damage to NEEScomm IT resources or could cause loss/damage to user, NEEScomm, or third-party data.
  • Receives a written request from federal, state, or local law enforcement agencies and complies with applicable NEEScomm policies.
  • Has a reasonable belief that an individual has or is violating NEEScomm policies, regulations, procedures, or rules using the accounts or devices in question.
  • Receives a written request from the NSF Director of Audits when an audit is investigating fiscal misconduct linked to the user whose account or device is in question.
  • Is authorized by an appropriate order of a court of competent jurisdiction and complies with applicable NEEScomm policies relating to the handling of such orders.

Again, without limiting the foregoing general rights, NEEScomm may, in its sole discretion, disclose the results of any general or individual monitoring or accessing permitted as described below in this section, including the contents and records of individual communications, to appropriate NEEScomm personnel or law enforcement agencies or use those results in appropriate NEEScomm disciplinary proceedings. Where applicable and warranted, the account or equipment user will be notified of the accessing or monitoring and the corrective actions taken.

The contents of the user’s e-mail, computer accounts, devices, and network traffic may be recorded and stored to prevent destruction should the information be requested pursuant to valid legal process.

The NEEScomm Center Director or his or her designee may authorize access in the event that he or she reasonably determines that: (a) there exists an emergency that materially threatens NEEScomm’s interests, (b) that emergency access is reasonably required in order to protect the NEEScomm’s interests, and © he or she specifies the scope and conditions of any permitted access. The CSO shall, as soon as reasonably possible after such emergency, make a written finding verifying the existence and satisfaction of the foregoing conditions.

Any access permitted hereunder shall be the minimum access required in order to protect NEEScomm’s interests.

Incident Response Policy

For the purpose of this section, we define an incident as any event involving NEEScomm IT resources which:

  • violates local, state or U.S. federal law, or
  • violates regulatory requirements which NEEScomm is obligated to honor, including without limitation regulatory requirements specified by NSF, or
  • violates a Purdue University policy, or
  • is determined to be harmful to the security and privacy of NEEScomm data, or IT resources, or
  • constitutes harassment under applicable law or University policy, or
  • involves the unexpected disruption of NEEScomm services.


A formal policy for the reporting of and response to IT incidents is necessary to ensure the secure operation of NEEScomm IT resources, to protect the data security and privacy of all NEEScomm users.

This section sets forth a set of policies for any NEEShub user to report any incident to the NEEScomm Cybersecurity team and for the efficient response to IT incidents in order to maintain the security and privacy of IT resources, data and other assets, as well as satisfy requirements of state and federal law.

Policy Statement

Reporting an incident

NEEScomm users should report any incident, even if they are not completely certain if it falls under the purview of the definition of incident given above, to the NEEScomm IT team at the earliest possible opportunity. The effect of the incident may be restricted to the site’s IT resource as it pertains to the operation of NEEScomm or it may apply to the NEEScomm IT resources at Purdue University. Examples of incidents which need to be reported are breakin to a legitimate user account, data being compromised because it lay unprotected for some length of time, detection of malicious scans originating from a site, and evidence of malware infecting machines at the sites which are used to access NEEScomm IT services. To report an incident, the user is expected to use either of the two options below:

  1. If the incident is likely restricted to the site’s IT resources only, then the user should use the web form at  to report the incident. The web form will guide the user to provide as much of the relevant details as possible, including, but not limited to, the hardware and the software configuration of the machines affected by the incident, the time of the first observation of the incident and the ingress point, and the extent of the effect on the site’s IT resources. The web form will ask the user to submit a contact telephone number so that the CIR can contact the user for remediation actions. The user should use a machine that is definitely not affected by the incident for this said reporting purpose. On receiving the report, a NEEScomm IT staff member will immediately acknowledge receipt and the CIR will generate the initial response within 8 hours. If the acknowledgment of receipt is not received by the user, then he/she should use option 2 immediately since it indicates the reporting of the incident was not successful.
  2. For broader scopes of the incident than in option 1 above, the user should use the toll-free number for NEEShub purposes. On dialing this toll-free number, the user will be directed to an option for reporting cybersecurity incidents. This number will be staffed 24×7 and the CIR will provide an initial response within 8 hours of the incident report filed through the telephone call.

Receiving Reports

The CIR upon receiving a report is responsible for assessing its veracity, determining whether or not the event constitutes an IT incident and classifying the IT incident, and initiating handling procedures. The CIR reserves the right, subject to applicable law and other applicable NEEScomm policies, to use the following resources for IT incident detection and/or response:

  1. System and application logs
  2. Passive network traffic monitoring (e.g., IDS, and other network packet analyzers)
  3. Active scanning of systems suspected of violating NEEScomm policy, or systems exhibiting symptoms of compromise
  4. Other resources as determined appropriate by the CIR and as allowed by NEEScomm policy and applicable law.

To facilitate accurate reporting, handling, and record keeping, the above two-step process should be followed for communicating an incident report. The CIR should also maintain a record of communication and data collection for all events reported to the CIR.


In order to facilitate the accurate and productive response to IT incidents, all IT incidents must be classified and assessed by the CIR for severity at their onset. As the IT incident progresses, its classification may be reevaluated and changed as necessary to ensure proper handling. We will follow the classification system outlined below for NEEShub incidents.

RATING Definition
Critical A vulnerability whose exploitation could damage NEEScomm IT services, without user action.
Important A vulnerability whose exploitation could result in compromise of the confidentiality, integrity, or availability of users data, or of the integrity or availability of processing resources.
Moderate Exploitability is mitigated to a significant degree by factors such as default configuration, auditing, or difficulty of exploitation.
Low A vulnerability whose exploitation is extremely difficult, or whose impact is minimal.

In some cases, IT incidents may fall under multiple classifications. When this happens, the classification with the highest severity should generally dictate the course of IT incident response. The CIR is responsible for providing and maintaining appropriate IT incident classification guidelines and resolution procedures.

Any incident which is of important or higher rating will be reported to NSF. NSF may impose further reporting requirements for security incidents, at its discretion.


After receiving a report, assessing its veracity, determining whether or not the event constitutes an IT incident, and classifying the IT incident, the CIR will determine if the IT incident warrants a formal response. IT incidents that do not warrant formal response at the NEEScomm IT level will be remanded to the appropriate Site IT Manager for handling. All reported events or IT incident must be documented throughout the response process.

If an event report does warrant formal IT incident response procedures by the CIR, it is the responsibility of the CIR to coordinate the appropriate resources for such response. If deemed appropriate by the CIR, a team of NEEScomm IT staff will be formed and led by the CIR for responding to the IT incident. The CIR is responsible for documenting appropriate procedures for responding to event reports and IT incidents, and coordinating incident response teams.

Business Continuity

In the course of responding to an IT incident it may be necessary, subject to applicable laws and NEEScomm policies, to require the suspension of involved or targeted services/systems in order to:

  • Protect NEEShub users, IT resources, other systems, data, and University assets from threats posed by the involved services/systems
  • Protect the service/system in question
  • To preserve evidence and facilitate the IT incident response process

The decision to suspend operations will be made by the CIR, and will require approval by the NEEScomm IT Director and the NEEScomm Center Director. In the case of mission critical applications, the CIR will make a good-faith effort to consult with the appropriate Site IT Manager, and if available, service/application owner before such suspensions are carried out. If, in the judgment of the CIR an excessive amount of time (giving due weight to the relative severity of the IT incident) has passed without response from the appropriate Site IT Manager or service/application owner, suspension may occur without consultation.

Any equipment not owned by a valid NEEScomm user which is using NEEScomm IT resources, and is found to be the target, source, or party to an IT incident may be subject to immediate suspension of services without notice until the issue has been resolved, or the subject system is no longer a threat. In all cases, it is the CIR who shall determine if and when a service suspension may be lifted.

In order to facilitate proper and timely handling of IT incident responses, it is necessary that network-connected devices can be identified and located as soon as possible. To this end, Site IT Managers are required to maintain an inventory of network-connectable devices under their control that are used to access NESScentral resources. This inventory should include, at a minimum, the primary location of the device, and the addresses for all network interfaces used by the device (per machine MAC address and all IP addresses for a machine).

Audit Policy for Site and NEEScomm IT Resources

NEEScomm’s comprehensive cybersecurity approach includes a security audit at each of the NEES sites performed once a year. The audits use security best practices to verify that each server-class system operating at a NEES site is operating in a manner to limit the potential for security incidents and breaches.

Security incidents and data breaches could invalidate data being collected by scientists, damage experimental equipment, and spread the damage to the NEEScomm IT resources. No system can be perfectly secure, to be sure. But regular audits of the system provide vital information for the regular upkeep and secure maintenance of the server systems. This section outlines the policies that will govern the audits of the site resources.


The objective of this policy section is to enable security audits with minimal impedance to the activities at each site and making the best possible use of the time and resources of IT personnel at the sites and at NEEScomm. It also lays out certain minimal requirements for the security audit as well as preferred practices that go above and beyond the minimal requirements. Yet another objective is to lay out the goals and the expected follow-on activities from a security audit.

Policy Statement

Schedule for the audit scans

Each Site IT Manager together with the NEEScomm CSO, or his designee, will work together to determine an appropriate time schedule for performing the audit. The audits will generally be done once a year. However, in the event that a security incident is suspected to have occurred or is anticipated, say due to the release of a dangerous malware that affects the IT systems at one or more sites, then further audits will be done. In all cases, the timing for the audit will be decided in consultation with the Site IT Managers, such that the site operations are minimally affected and the resources of the site IT staff are optimally utilized.

Running the audit scans

The set of scan software that will be a part of the audit will be provided by NEEScomm IT. We will be using a suite of audit software, with one necessary requirement being that each software be actively maintained with updates to the vulnerability signatures. The entire audit will consist of multiple scans, each using a different software package. We will seek to perform the scans at different layers of the software stack, from the network to the application level.

It is desirable that the audits be done in a manner that is as automated as possible. For this NEEScomm will generate, as far as practicable, scripts to run the audit scans automatically, collect the results, and perform a first-pass automated analysis of the scan results to identify any security vulnerabilities. The scan will be done in two modes – one where the source is a machine within the university that the site is a part of (to mimic attackers from inside the university) and the second where the source is from the general internet outside the university (to mimic external attackers). It is expected that for such technical reasons as well as operational reasons, the execution of the audit scans will be done with the participation of the Site IT Manager. The parties will determine which machines will be a part of the scan. This will be derived from the inventory of the site IT assets that will be done at the beginning of each project year. All the IT assets that are related to NEES activities, including, but not restricted to the following will be a part of the security audit – local data repositories, and machines operated by the NEES network and used to access NEEShub data and NEEShub services.

Actions following the audit scans

Each piece of scan software automatically generates reports of what it found in the target systems and usually, classifies each observation in terms of severity. These reports will serve as the starting point for a more targeted and manual analysis of the report by the NEEScomm security staff. The objective of this is to identify vulnerabilities that are very difficult to be covered by any automated analysis script due to the evolving nature of the computer security threats. A second practical objective of the manual analysis is to remove incidences of false positives that have been observed in the automatically generated reports. Such false positives arise because it is difficult to document all the configuration details of the IT systems that affect the results of the security scans; even if a configuration detail is documented, it is often present in a form (such as, free text without any standardized structure) that cannot be parsed easily by the automated scan tools. If this manual analysis finds any vulnerability or evidence of a security breach, the Site IT Manager will be immediately contacted and an incident report initiated.

A formal report will be generated once a year that summarizes the results of the audits for each site. The report will identify the assets that were a part of the audit, where the audit did find vulnerabilities and security breaches, and remediation actions, both short term and long term. This report will not be for public disclosure, keeping in view the security sensitive nature of the information. The report will be seen only by NEEScomm members, site IT members, and NSF.

Low intensity periodic scans

In addition to the annual audits, NEEScomm will install scan software that can do periodic low intensity audit scans, typically every two weeks. Such software will be from reputable sources (often from the same sources that provide the software for the annual audits). The goal of these periodic scans is to identify vulnerabilities as they come up and any possible security breaches, closer to the time of occurrence of the breach than would be possible through the annual audits. For these periodic scans, it is again important that the site activities be minimally affected, if at all. Therefore, the schedules for these scans and their priority levels will be decided by the NEEScomm CSO in consultation with the Site IT Managers. Further, any Site IT Manager may identify a critical period of operation of the site facilities where no disturbance to the normal operation should be allowed. NEEScomm IT will abide by such schedules and disable the periodic scans during these periods.

NEEScomm IT scans

The NEEScomm IT resources (at Purdue University) will also be the targets of security scans in a manner similar to the process outlined above for the site IT resources with the following modifications. We will not need any coordination with the site IT managers; the coordination will be based on release schedule of NEEShub software so that any users are not affected. Further, we will be performing source level scans of the NEEShub software, since the source code will be available to us. These are static scans that are run on the code, as opposed to dynamic scans that operate when the code is being executed. The scans that we propose to implement will serve the purpose that before the software is deployed, vulnerabilities will have been identified and rectified. The static scans can be complemented with dynamic scans, which have the added benefit over the traditional security scans, that they discover the configuration of the web applications (directory structure, which modules are actually being used) and can therefore target the security scans more precisely.

Audit of control systems

Some NEES sites have SCADA control equipments which are accessible from external IP addresses. This is required so that legitimate external entities can monitor the equipment and optionally push in software patches. In such cases, we recommend using firewall rules to restrict access to specific IP addresses, or ranges of IP addresses. Further, we recommend changing the default password immediately upon installation of the control system.


In this document, we have outlined the NEES Cyberinfrastructure (NEES CI) security plan that delineates the responsibilities, roles, and expected behavior of all individuals who access NEEScomm IT services and the policies governing the security controls that will be used to minimize the risks of cybersecurity incidents. All site IT personnel and NEEScomm IT staff should become familiar with this document. The security plan will be reviewed and updated at least annually, and further on an as-needed basis, to reflect enhancements to the NEEScomm IT services and to react to new security threats from the ever-changing computer security field.
