NIST 800-53 Compliance
The National Institute of Standards and Technology (NIST) is a world-renowned non-regulatory agency providing detailed guidelines for improving information security within federal agencies and associated organizations. Ekran System cooperates with NIST and can help you build compliant data protection and digital infrastructure protection systems.
Ekran System is listed in NIST Special Publication (SP) 1800-18 Privileged Account Management for the Financial Services Sector.
NIST 800-53 compliance: who needs it and why?
As a non-regulatory agency of the US Department of Commerce, NIST focuses on researching and establishing general guidelines and standards that federal agencies must meet.
In particular, NIST Special Publication 800-53: Security and Privacy Controls for Information Systems and Organizations is a set of guidelines and recommendations for architecting and managing secure information systems. Compliance with NIST 800-53 security control guidelines is the main key to achieving compliance with the Federal Information Security Management Act of 2002 (FISMA) and Federal Information Processing Standards (FIPS) requirements.
Since 2005, NIST has released several revisions of SP 800-53. The latest officially released version is Revision 4, published in 2013, with the official NIST 800-53 summary having been released a year later. However, according to the NIST schedule, the final publication of Revision 5 is planned for summer 2019.
The Ekran System platform is the ultimate NIST 800-53 compliance software, covering the core security controls and making it easy to secure your organization’s critical assets and sensitive data.
Using Ekran System to meet NIST 800-53 requirements
Ekran System helps you comply with NIST 800-53 security controls by providing monitoring and auditing of work involving sensitive data, identity and access management, and incident response tool sets.
NIST 800-53 Revision 4 provides detailed guidelines for three minimum security controls that cover 18 control families.
|Minimum security controls||Control families|
AC – Access Control
AU – Audit and Accountability
AT – Awareness and Training
CM – Configuration Management
CP – Contingency Planning
IA – Identification and Authentication
IR – Incident Response
MA – Maintenance
MP – Media Protection
PS – Personnel Security
PE – Physical and Environmental Protection
PL – Planning
PM – Program Management
RA – Risk Assessment
CA – Security Assessment and Authorization
SC – System and Communications Protection
SI – System and Information Integrity
SA – System and Services Acquisition
For each of these families, there’s a large NIST 800-53 controls list that includes security controls with different impact levels. However, organizations don't need to implement all of these controls to comply with FISMA and NIST SP 800-53. They need to follow the baseline recommendations for architecting information security systems but are free to choose which security tools and solutions to use for that purpose.
With Ekran System, you can implement the necessary security controls for NIST 800-53 control families including:
- Audit and Accountability (AU)
- Access Control (AC)
- Identification and Authentication (IA)
- Incident Response (IR)
As NIST 800-53 compliance software, Ekran System fully covers all of the controls in the Audit and Accountability family while also covering the majority of security controls in other control families.
The Access Control family includes a wide range of security controls for ensuring the proper level of access management. Ekran System includes a number of features that can help you meet critical NIST 800-53 access control requirements, including:
- AC-2 Account management – Ekran System contains a set of authentication features that can be used for improving your current account management system, including identity management, two-factor authentication, and privileged access management (PAM).
- AC-3 Access enforcement – Ekran System’s access management capabilities allow authorization approval to be enforced according to your access control policies.
- AC-8 System use notification – Ekran System can be configured to display notifications about login attempts within the protected perimeter.
Privileged Access and Session Management (PASM) is one of Ekran System’s key access management features. Using PASM, you can manage user privileges effectively, ensure granular time-limited access to critical assets, and monitor and manage sessions initiated by privileged users. Other access management features provided by Ekran System include manual access approval, one-time passwords, secondary authentication for shared accounts, and a free two-factor authentication tool.
Audit and Accountability
The NIST Audit and Accountability control family covers security practices required for establishing a reliable accountability system within an organization. NIST recommends performing detailed and continuous audits to detect possible cybersecurity threats and investigate incidents. Auditing and accountability are also needed to prove compliance to an external auditor.
Ekran System is a comprehensive user activity monitoring solution that can provide you with a detailed audit log of every event that happens on a monitored endpoint. The platform covers all security controls within this control family, including:
- AU-2 Audit events – Ekran System can be configured to monitor all or only specific events.
- AU-3 Content of audit records – Monitoring results are recorded in a searchable video format, indexed with metadata such as keystrokes, commands entered, web pages visited, names of files opened and applications launched, etc.
- AU-6 Audit review, analysis, and reporting – Ekran System provides a rich set of reporting capabilities. Reports can be generated manually or automatically according to a set schedule.
- AU-8 Time stamps – All recorded data is coupled with timestamps.
- AU-9 Protection of audit information – All records made by Ekran System are tamper-proof. Any unauthorized access can be detected with the help of internal logs that can be accessed via Ekran’s web-based Management Tool. The Export session feature delivers reports and monitoring details in a format that can't be altered.
- AU-14 Session audit – By default, Ekran System records all user sessions initiated on the target endpoint, including privileged user sessions.
Identification and Authentication
The Identification and Authentication control family covers a set of security controls necessary for uniquely identifying each user and device accessing your network. The ability to identify each user accessing the system and then reliably connect them to a specific event is crucial for detecting potential threats and investigating security incidents.
As a universal NIST 800-53 compliance solution, Ekran System provides a number of identity and access management features for ensuring a high level of user identity verification, including secondary authentication and multi-factor authentication (MFA). These capabilities enable identification of each user even for shared accounts and cover NIST Identification and Authentication controls such as:
- IA-2 Identification and authorization (organizational users) – the PASM and MFA capabilities provided by Ekran System allow you to uniquely identify internal employees, subcontractors, and other organizational users.
- IA-8 Identification and authorization (non-organizational users) – Ekran System’s secondary authentication feature ensures additional identification of every user logging into the system under a shared account.
The Incident Response control family covers one of the most important parts of ensuring the protection of sensitive data: what needs to be done in case of a security incident. Ekran System provides actionable tools to meet the requirements of this NIST family of controls:
- IR-4 Incident handling – Ekran System provides an alerting system to detect incidents in a timely manner and a set of manual and automated incident response tools for everything from sending warning messages to blocking users.
- IR-5 Incident monitoring – The alerting functionality in Ekran System supports predefined template-based incident triggers and fully customizable trigger rules. When an incident is detected, a security officer is notified and provided with all context needed to respond quickly.
In addition, Ekran System can export data in a forensic format for further cybersecurity incident investigation and analysis.
However, NIST SP 800-53 isn’t the only IT security standard that Ekran System can help you comply with. Using Ekran System also makes it much easier to meet the requirements of other industry standards and regulations, including FISMA, HIPAA, and PCI DSS.
