Finding ID Severity Title Description
V-265870 High Microsoft SQL Server products must be a version supported by the vendor. Unsupported commercial and database systems should not be used because fixes to newly identified bugs will not be implemented by the vendor. The lack of support can result in potential vulnerabilities. Systems at unsupported servicing levels or releases will not receive security updates for new vulnerabilities, which leaves them subject...
V-214046 High Applications must obscure feedback of authentication information during the authentication process to protect the information from possible exploitation/use by unauthorized individuals. To prevent the compromise of authentication information, such as passwords and PINs, during the authentication process, the feedback from the information system must not provide any information that would allow an unauthorized user to compromise the authentication mechanism. Obfuscation of user-provided information when typed into the system is a method...
V-214045 High When using command-line tools such as SQLCMD in a mixed-mode authentication environment, users must use a logon method that does not expose the password. To prevent the compromise of authentication information, such as passwords and PINs, during the authentication process, the feedback from the information system must not provide any information that would allow an unauthorized user to compromise the authentication mechanism. Obfuscation of user-provided information when typed into the system is a method...
V-214028 High The SQL Server default account [sa] must be disabled. SQL Server's [sa] account has special privileges required to administer the database. The [sa] account is a well-known SQL Server account and is likely to be targeted by attackers and thus more prone to providing unauthorized access to the database. This [sa] default account is administrative and could lead to...
V-214023 High SQL Server must implement NIST FIPS 140-2 or 140-3 validated cryptographic modules to generate and validate cryptographic hashes. Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. The application must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated. For detailed information, refer to NIST FIPS Publication...
V-214022 High SQL Server must implement NIST FIPS 140-2 or 140-3 validated cryptographic modules to provision digital signatures. Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. The application must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated. For detailed information, refer to NIST FIPS Publication...
V-213972 High SQL Server must protect the confidentiality and integrity of all information at rest. This control is intended to address the confidentiality and integrity of information at rest in non-mobile devices and covers user information and system information. Information at rest refers to the state of information when it is located on a secondary storage device (e.g., disk drive, tape drive) within an organizational...
V-213969 High SQL Server must use NIST FIPS 140-2 or 140-3 validated cryptographic modules for cryptographic operations. Use of weak or not validated cryptographic algorithms undermines the purposes of utilizing encryption and digital signatures to protect data. Weak algorithms can be easily broken, and not validated cryptographic modules may not implement algorithms correctly. Unapproved cryptographic modules or algorithms should not be relied on for authentication, confidentiality, or...
V-213968 High SQL Server must enforce authorized access to all PKI private keys stored/utilized by SQL Server. The DoD standard for authentication is DoD-approved PKI certificates. PKI certificate-based authentication is performed by requiring the certificate holder to cryptographically prove possession of the corresponding private key. If the private key is stolen, an attacker can use the private key(s) to impersonate the certificate holder. In cases where SQL...
V-213967 High Confidentiality of information during transmission is controlled through the use of an approved TLS version. Transport Layer Security (TLS) encryption is a required security setting as a number of known vulnerabilities have been reported against Secure Sockets Layer (SSL) and earlier versions of TLS. Encryption of private information is essential to ensuring data confidentiality. If private information is not encrypted, it can be intercepted and...
V-213966 High If passwords are used for authentication, SQL Server must transmit only encrypted representations of passwords. The DOD standard for authentication is DOD-approved PKI certificates. Authentication based on User ID and Password may be used only when it is not possible to employ a PKI certificate and requires AO approval. In such cases, passwords need to be protected at all times, and encryption is the standard...
V-213964 High If DBMS authentication using passwords is employed, SQL Server must enforce the DOD standards for password complexity and lifetime. Windows Authentication is the default authentication mode and is much more secure than SQL Server Authentication. Windows Authentication uses Kerberos security protocol, provides password policy enforcement with regard to complexity validation for strong passwords, provides support for account lockout, and supports password expiration. A connection made using Windows Authentication is...
V-213952 High SQL Server software installation account must be restricted to authorized users. When dealing with change control issues, it should be noted any changes to the hardware, software, and/or firmware components of the information system and/or application can have significant effects on the overall security of the system. If the system were to allow any user to make changes to software libraries,...
V-213932 High SQL Server must enforce approved authorizations for logical access to information and system resources in accordance with applicable access control policies. Authentication with a DoD-approved PKI certificate does not necessarily imply authorization to access SQL Server. To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DoD-approved PKIs, all DoD systems, including databases, must be properly configured to implement access control policies. Successful...
V-213930 High SQL Server must integrate with an organization-level authentication/access mechanism providing account management and automation for all users, groups, roles, and any other principals. Enterprise environments make account management for applications and databases challenging and complex. A manual process for account management functions adds the risk of a potential oversight or other error. Managing accounts for the same person in multiple places is inefficient and prone to problems with consistency and synchronization. A comprehensive...

This information helps Microsoft improve the product to better meet customer...
V-214025 Medium The system SQL Server must off-load audit data to a separate log management facility; this must be continuous and in near real time for systems with a network connection to the storage facility and weekly or more often for stand-alone systems. Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading is a common process in information systems with limited audit storage capacity. The system SQL Server may write audit records to database tables, to files in the file system, to other kinds of local repository,...
V-214024 Medium SQL Server must implement NIST FIPS 140-2 or 140-3 validated cryptographic modules to protect unclassified information requiring confidentiality and cryptographic protection, in accordance with the data owners requirements. Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. The application must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated. It is the responsibility of the data owner...
V-214021 Medium SQL Server must generate audit records for all direct access to the database(s). In this context, direct access is any query, command, or call to SQL Server that comes from any source other than the application(s) that it supports. Examples would be the command line or a database management utility program. The intent is to capture all activity from administrative and non-standard sources.
V-214020 Medium SQL Server must generate audit records when successful and unsuccessful accesses to objects occur. Without tracking all or selected types of access to all or selected objects (tables, views, procedures, functions, etc.), it would be difficult to establish, correlate, and investigate the events relating to an incident, or identify those responsible for one. In an SQL environment, types of access include, but are not...
V-214018 Medium SQL Server must generate audit records when concurrent logons/connections by the same user from different workstations occur. For completeness of forensic analysis, it is necessary to track who logs on to SQL Server. Concurrent connections by the same user from multiple workstations may be valid use of the system; or such connections may be due to improper circumvention of the requirement to use the CAC for authentication;...
V-214017 Medium SQL Server must generate audit records showing starting and ending time for user access to the database(s). For completeness of forensic analysis, it is necessary to know how long a user's (or other principal's) connection to SQL Server lasts. This can be achieved by recording disconnections, in addition to logons/connections, in the audit logs. Disconnection may be initiated by the user or forced by the system (as...
V-214016 Medium SQL Server must generate audit records when unsuccessful attempts to execute privileged activities or other system-level access occur. Without tracking privileged activity, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.

V-214015 Medium SQL Server must generate audit records for all privileged activities or other system-level access. Without tracking privileged activity, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. System documentation should include a definition of the functionality considered privileged. A privileged function in this context is any operation that modifies the structure of...
V-214014 Medium SQL Server must generate audit records when successful and unsuccessful logons or connection attempts occur. For completeness of forensic analysis, it is necessary to track who/what (a user or other principal) logs on to SQL Server. It is also necessary to track failed attempts to log on to SQL Server. While positive identification may not be possible in a case of failed authentication, as much...
V-214012 Medium SQL Server must generate audit records when successful and unsuccessful attempts to delete categorized information (e.g., classification levels/security levels) occur. Changes in categorized information must be tracked. Without an audit trail, unauthorized access to protected data could go undetected. To aid in diagnosis, it is necessary to keep track of failed attempts in addition to the successful ones. For detailed information on categorizing information, refer to FIPS Publication 199, Standards...
V-214010 Medium SQL Server must generate audit records when successful and unsuccessful attempts to delete security objects occur. The removal of security objects from the database/DBMS would seriously degrade a system's information assurance posture. If such an action is attempted, it must be logged. To aid in diagnosis, it is necessary to keep track of failed attempts in addition to the successful ones. Satisfies: SRG-APP-000501-DB-000336
V-214008 Medium SQL Server must generate audit records when successful and unsuccessful attempts to delete privileges/permissions occur. Changes in the permissions, privileges, and roles granted to users and roles must be tracked. Without an audit trail, unauthorized elevation or restriction of privileges could go undetected. Elevated privileges give users access to information and functionality that they should not have; restricted privileges wrongly deny access to authorized users....
V-214006 Medium SQL Server must generate audit records when successful and unsuccessful attempts to modify categorized information (e.g., classification levels/security levels) occur. Changes in categories of information must be tracked. Without an audit trail, unauthorized access to protected data could go undetected.

V-213998 Medium SQL Server must generate audit records when successful and unsuccessful attempts to access categorized information (e.g., classification levels/security levels) occur. Changes in categorized information must be tracked. Without an audit trail, unauthorized access to protected data could go undetected. For detailed information on categorizing information, refer to FIPS Publication 199, Standards for Security Categorization of Federal Information and Information Systems, and FIPS Publication 200, Minimum Security Requirements for Federal Information...
V-213995 Medium SQL Server must be able to generate audit records when successful and unsuccessful attempts to access security objects occur. Changes to the security configuration must be tracked. This requirement applies to situations where security data is retrieved or modified via data manipulation operations, as opposed to via specialized security functionality. In an SQL environment, types of access include, but are not necessarily limited to: SELECT INSERT UPDATE DELETE EXECUTE...
V-213994 Medium Security-relevant software updates to SQL Server must be installed within the time period directed by an authoritative source (e.g. IAVM, CTOs, DTMs, and STIGs). Security flaws with software applications, including database management systems, 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...
V-213993 Medium When updates are applied to SQL Server software, any software components that have been replaced or made unnecessary must be removed. Previous versions of DBMS components that are not removed from the information system after updates have been installed may be exploited by adversaries. Some DBMSs' installation tools may remove older versions of software automatically from the information system. In other cases, manual review and removal will be required. In planning...
V-213992 Medium SQL Server services must be configured to run under unique dedicated user accounts. Database management systems can maintain separate execution domains for each executing process by assigning each process a separate address space. Each process has a distinct address space so that communication between processes is controlled through the security functions, and one process cannot modify the executing code of another process. Maintaining...
V-213991 Medium SQL Server must maintain a separate execution domain for each executing process. Database management systems can maintain separate execution domains for each executing process by assigning each process a separate address space. Each process has a distinct address space so that communication between processes is controlled through the security functions, and one process cannot modify the executing code of another process. Maintaining...
V-213990 Medium SQL Server must disable network functions, ports, protocols, and services deemed by the organization to be nonsecure, in accord with the Ports, Protocols, and Services Management (PPSM) guidance. Use of nonsecure network functions, ports, protocols, and services exposes the system to avoidable threats.
V-213989 Medium SQL Server must produce audit records of its enforcement of access restrictions associated with changes to the configuration of SQL Server or database(s). Without auditing the enforcement of access restrictions against changes to configuration, it would be difficult to identify attempted attacks and an audit trail would not be available for forensic investigation for after-the-fact actions. Enforcement actions are the methods or mechanisms used to prevent unauthorized changes to configuration settings. Enforcement action...
V-213988 Medium Windows must enforce access restrictions associated with changes to the configuration of the SQL Server instance. Failure to provide logical access restrictions associated with changes to configuration may have significant effects on the overall security of the system. When dealing with access restrictions pertaining to change control, it should be noted that any changes to the hardware, software, and/or firmware components of the information system can...
V-213987 Medium SQL Server must enforce access restrictions associated with changes to the configuration of the instance.

When dealing with access restrictions pertaining to change control, it should be noted that any changes to the hardware, software, and/or firmware components of the information system can...
V-213986 Medium SQL Server must record time stamps in audit records and application data that can be mapped to Coordinated Universal Time (UTC, formerly GMT). If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis. Time stamps generated by SQL Server must include date and time. Time is commonly expressed in Coordinated Universal Time (UTC), a modern continuation of Greenwich Mean Time (GMT), or...
V-213985 Medium SQL Server must provide an immediate real-time alert to appropriate support staff of all audit log failures. It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impending failure of the audit capability, and system operation may be adversely affected. The appropriate...
V-213984 Medium SQL Server must provide a warning to appropriate support staff when allocated audit record storage volume reaches 75% of maximum audit record storage capacity. Organizations are required to use a central log management system, so, under normal conditions, the audit space allocated to SQL Server on its own server will not be an issue. However, space will still be required on the server for SQL Server audit records in transit, and, under abnormal conditions,...
V-213983 Medium SQL Server must allocate audit record storage capacity in accordance with organization-defined audit record storage requirements. In order to ensure sufficient storage capacity for the audit logs, SQL Server must be able to allocate audit record storage capacity. Although another requirement (SRG-APP-000515-DB-000318) mandates that audit data be off-loaded to a centralized log management system, it remains necessary to provide space on the database server to serve...
V-213980 Medium Use of credentials and proxies must be restricted to necessary cases only. In certain situations, to provide required functionality, a DBMS needs to execute internal logic (stored procedures, functions, triggers, etc.) and/or external code modules with elevated privileges. However, if the privileges required for execution are at a higher level than the privileges assigned to organizational users invoking the functionality applications/programs, those...
V-213979 Medium SQL Server must prevent non-privileged users from executing privileged functions, to include disabling, circumventing, or altering implemented security safeguards/countermeasures. Preventing non-privileged users from executing privileged functions mitigates the risk that unauthorized individuals or processes may gain unnecessary access to information or privileges. System documentation should include a definition of the functionality considered privileged. Depending on circumstances, privileged functions can include, for example, establishing accounts, performing system integrity checks, or...
V-213978 Medium SQL Server must reveal detailed error messages only to documented and approved individuals or roles. If SQL Server provides too much information in error logs and administrative messages to the screen, this could lead to compromise. The structure and content of error messages need to be carefully considered by the organization and development team. The extent to which the information system is able to identify...
V-213977 Medium Access to database files must be limited to relevant processes and to authorized, administrative users. SQL Server must prevent unauthorized and unintended information transfer via shared system resources. Permitting only SQL Server processes and authorized, administrative users to have access to the files where the database resides helps ensure that those files are not shared inappropriately and are not open to backdoor access and manipulation.
V-213976 Medium SQL Server must prevent unauthorized and unintended information transfer via Instant File Initialization (IFI). The purpose of this control is to prevent information, including encrypted representations of information, produced by the actions of a prior user/role (or the actions of a process acting on behalf of a prior user/role) from being available to any current user/role (or current process) that obtains access to a...
V-213975 Medium SQL Server must prevent unauthorized and unintended information transfer via shared system resources. The purpose of this control is to prevent information, including encrypted representations of information, produced by the actions of a prior user/role (or the actions of a process acting on behalf of a prior user/role) from being available to any current user/role (or current process) that obtains access to a...
V-213974 Medium The Master Key must be backed up and stored in a secure location that is not on the SQL Server. Backup and recovery of the Master Key may be critical to the complete recovery of the database. Not having this key can lead to loss of data during recovery.
V-213973 Medium The Service Master Key must be backed up and stored in a secure location that is not on the SQL Server. Backup and recovery of the Service Master Key may be critical to the complete recovery of the database. Creating this backup should be one of the first administrative actions performed on the server. Not having this key can lead to loss of data during recovery.
V-213971 Medium SQL Server must maintain the authenticity of communications sessions by guarding against man-in-the-middle attacks that guess at Session ID values. One class of man-in-the-middle, or session hijacking, attack involves the adversary guessing at valid session identifiers based on patterns in identifiers already known. The preferred technique for thwarting guesses at Session IDs is the generation of unique session identifiers using a FIPS 140-2 or FIPS 140-3 approved random number generator....
V-213970 Medium SQL Server must uniquely identify and authenticate non-organizational users (or processes acting on behalf of non-organizational users). Non-organizational users include all information system users other than organizational users, which include organizational employees or individuals the organization deems to have equivalent status of employees (e.g., contractors, guest researchers, individuals from allied nations). Non-organizational users must be uniquely identified and authenticated for all accesses other than those accesses explicitly...
V-213965 Medium Contained databases must use Windows principals. OS/enterprise authentication and identification must be used (SRG-APP-000023-DB-000001). Native DBMS authentication may be used only when circumstances make it unavoidable, and must be documented and Authorizing Official (AO)-approved. The DOD standard for authentication is DOD-approved PKI certificates. Authentication based on User ID and Password may be used only when it...
V-213963 Medium SQL Server must uniquely identify and authenticate organizational users (or processes acting on behalf of organizational users). To assure accountability and prevent unauthenticated access, organizational users must be identified and authenticated to prevent potential misuse and compromise of the system. Organizational users include organizational employees or individuals the organization deems to have equivalent status of employees (e.g., contractors). Organizational users (and any processes acting on behalf of...
V-213962 Medium SQL Server must be configured to prohibit or restrict the use of organization-defined ports, as defined in the PPSM CAL and vulnerability assessments. In order to prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable or restrict unused or unnecessary physical and logical ports on information systems. Applications are capable of providing a wide variety of functions and services....
V-213961 Medium SQL Server must be configured to prohibit or restrict the use of organization-defined protocols as defined in the PPSM CAL and vulnerability assessments.

It is detrimental for software products to provide, or install by default, functionality exceeding requirements...
V-213953 Medium Database software, including DBMS configuration files, must be stored in dedicated directories, separate from the host OS and other applications. When dealing with change control issues, it should be noted any changes to the hardware, software, and/or firmware components of the information system and/or application can potentially have significant effects on the overall security of the system. Multiple applications can provide a cumulative negative effect. A vulnerability and subsequent exploit...
V-213951 Medium SQL Server must limit privileges to change software modules, to include stored procedures, functions and triggers, and links to software external to SQL Server. If the system were to allow any user to make changes to software libraries, then those changes might be implemented without undergoing the appropriate testing and approvals that are part of a robust change management process. Accordingly, only qualified and authorized individuals must be allowed to obtain access to information...
V-213950 Medium SQL Server must limit privileges to change software modules and links to software external to SQL Server. If the system were to allow any user to make changes to software libraries, then those changes might be implemented without undergoing the appropriate testing and approvals that are part of a robust change management process. Accordingly, only qualified and authorized individuals must be allowed to obtain access to information...
V-213948 Medium SQL Server must protect its audit configuration from authorized and unauthorized access and modification. Protecting audit data also includes identifying and protecting the tools used to view and manipulate log data. Therefore, protecting audit tools is necessary to prevent unauthorized operation on audit data. Applications providing tools to interface with audit data will leverage user permissions and roles identifying the user accessing the tools...
V-213944 Medium The audit information produced by SQL Server must be protected from unauthorized access, modification, and deletion. If audit data were to become compromised, then competent forensic analysis and discovery of the true source of potentially malicious system activity is difficult, if not impossible, to achieve. In addition, access to audit records provides information an attacker could potentially use to his or her advantage. To ensure the...
V-213943 Medium SQL Server must be configurable to overwrite audit log records, oldest first (First-In-First-Out - FIFO), in the event of unavailability of space for more audit log records. It is critical that when SQL Server is at risk of failing to process audit logs as required, it take action to mitigate the failure. Audit processing failures include; software/hardware errors; failures in the audit capturing mechanisms; and audit storage capacity being reached or exceeded. Responses to audit failure depend...
V-213942 Medium SQL Server must by default shut down upon audit failure, to include the unavailability of space for more audit log records; or must be configurable to shut down upon audit failure. It is critical that when SQL Server is at risk of failing to process audit logs as required, it takes action to mitigate the failure. Audit processing failures include: software/hardware errors; failures in the audit capturing mechanisms; and audit storage capacity being reached or exceeded. Responses to audit failure depend...
V-213941 Medium SQL Server must include additional, more detailed, organization-defined information in the audit records for audit events identified by type, location, or subject. Information system auditing capability is critical for accurate forensic analysis. Reconstruction of harmful events or forensic analysis is not possible if audit records do not contain enough information. To support analysis, some types of events will need information to be logged that exceeds the basic requirements of event type, time...
V-213940 Medium SQL Server must initiate session auditing upon startup. Session auditing is for use when a user's activities are under investigation. To be sure of capturing all activity during those periods when session auditing is in use, it needs to be in operation for the whole time SQL Server is running.
V-213939 Medium SQL Server must generate audit records when successful/unsuccessful attempts to retrieve privileges/permissions occur. Under some circumstances, it may be useful to monitor who/what is reading privilege/permission/role information. Therefore, monitoring must be possible. DBMSs typically make such information available through views or functions. This requirement addresses explicit requests for privilege/permission/role membership information. It does not refer to the implicit retrieval of privileges/permissions/role memberships that...
V-213937 Medium SQL Server must allow only the ISSM (or individuals or roles appointed by the ISSM) to select which auditable events are to be audited. Without the capability to restrict which roles and individuals can select which events are audited, unauthorized personnel may be able to prevent or interfere with the auditing of critical events. Suppression of auditing could permit an adversary to evade detection. Misconfigured audits can degrade the system's performance by overwhelming the...
V-213936 Medium SQL Server must be configured to generate audit records for DoD-defined auditable events within all DBMS/database components. Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within SQL Server (e.g., process, module). Certain specific application functionalities may be audited as...
V-213935 Medium SQL Server must protect against a user falsely repudiating by ensuring only clearly unique Active Directory user accounts can connect to the instance. Non-repudiation of actions taken is required in order to maintain data integrity. Examples of particular actions taken by individuals include creating information, sending a message, approving information (e.g., indicating concurrence or signing a contract), and receiving a message. Non-repudiation protects against later claims by a user of not having created,...
V-213934 Medium SQL Server must protect against a user falsely repudiating by ensuring the NT AUTHORITY SYSTEM account is not used for administration. Non-repudiation of actions taken is required in order to maintain data integrity. Examples of particular actions taken by individuals include creating information, sending a message, approving information (e.g., indicating concurrence or signing a contract), and receiving a message. Non-repudiation protects against later claims by a user of not having created,...
V-213933 Medium SQL Server must protect against a user falsely repudiating by ensuring all accounts are individual, unique, and not shared. Non-repudiation of actions taken is required in order to maintain data integrity. Examples of particular actions taken by individuals include creating information, sending a message, approving information (e.g., indicating concurrence or signing a contract), and receiving a message. Non-repudiation protects against later claims by a user of not having created,...
V-213931 Medium SQL Server must be configured to utilize the most-secure authentication method available. Enterprise environments make account management for applications and databases challenging and complex. A manual process for account management functions adds the risk of a potential oversight or other error. Managing accounts for the same person in multiple places is inefficient and prone to problems with consistency and synchronization. A comprehensive...
V-213929 Medium SQL Server must limit the number of concurrent sessions to an organization-defined number per user for all accounts and/or account types. Database management includes the ability to control the number of users and user sessions utilizing SQL Server. Unlimited concurrent connections to SQL Server could allow a successful denial-of-service (DoS) attack by exhausting connection resources; and a system can also fail or be degraded by an overload of legitimate users. Limiting...
V-214044 Low If the SQL Server Browser Service is specifically required and approved, SQL instances must be hidden. The SQL Server Browser simplifies the administration of SQL Server, particularly when multiple instances of SQL Server coexist on the same computer. It avoids the need to hard-assign port numbers to the instances and to set and maintain those port numbers in client systems. It enables administrators and authorized users...
V-214042 Low The SQL Server Browser service must be disabled unless specifically required and approved. The SQL Server Browser simplifies the administration of SQL Server, particularly when multiple instances of SQL Server coexist on the same computer. It avoids the need to hard-assign port numbers to the instances and to set and maintain those port numbers in client systems. It enables administrators and authorized users...
