Adversaries may take control of preexisting sessions with remote services to move laterally in an environment. Users may use valid credentials to log into a service specifically designed to accept remote connections, such as telnet, SSH, and RDP. When a user logs into a service, a session will be established that will allow them to maintain a continuous interaction with that service.
Adversaries may commandeer these sessions to carry out actions on remote systems. Remote Service Session Hijacking differs from use of Remote Services because it hijacks an existing session rather than creating a new session using Valid Accounts.(Citation: RDP Hijacking Medium)(Citation: Breach Post-mortem SSH Hijack)

| PR.AA-05.03 | Service accounts | Mitigates | T1563 | Remote Service Session Hijacking |
Comments
This diagnostic statement is for the implementation of security controls for service accounts (i.e., accounts used by systems to access other systems), such as granting service accounts only the minimum necessary permissions.

| PR.AA-05.02 | Privileged system access | Mitigates | T1563 | Remote Service Session Hijacking |
Comments
This diagnostic statement protects against Remote Service Session Hijacking through the use of privileged account management and the use of multi-factor authentication.

Comments
This diagnostic statement protects against Remote Service Session Hijacking through the use of privileged account management. Employing auditing, privilege access management, and just in time access protects against adversaries trying to obtain illicit access to critical systems.

| PR.PS-01.03 | Configuration deviation | Mitigates | T1563 | Remote Service Session Hijacking |
Comments
This diagnostic statement provides protection from Remote Service Session Hijacking through the implementation of security configuration baselines for OS, software, file integrity monitoring and imaging. Security baseline configuration of the Operating System and integrity checking can help protect against adversaries attempting to compromise and modify software and its configurations.

| PR.AA-01.02 | Physical and logical access | Mitigates | T1563 | Remote Service Session Hijacking |
Comments
This diagnostic statement describes how the organization ensures users are identified and authenticated before accessing systems, applications, and hardware, with logical access controls permitting access only to authorized individuals with legitimate business needs. Logical access controls in relation to systems can refer to the use of MFA, user account management, and other role-based access control mechanisms to enforce policies for authentication and authorization of user accounts.

| PR.IR-01.01 | Network segmentation | Mitigates | T1563 | Remote Service Session Hijacking |
Comments
This diagnostic statement is for the implementation of network segmentation which helps prevent access to critical systems and sensitive information. Blocking network traffic that is not necessary can mitigate, or at least alleviate, use of remote services to move laterally in an environment.

| PR.IR-01.03 | Network communications integrity and availability | Mitigates | T1563 | Remote Service Session Hijacking |
Comments
This diagnostic statement protects against Remote Service Session Hijacking through the use of secure network configurations, architecture, implementations of zero trust architecture, and segmentation.

| PR.IR-01.05 | Remote access protection | Mitigates | T1563 | Remote Service Session Hijacking |
Comments
This diagnostic statement implements security controls and restrictions for remote user access to systems. Remote user access control involves managing and securing how users remotely access systems, such as through encrypted connections and account use policies, which help prevent adversary access.

| PR.IR-01.06 | Production environment segregation | Mitigates | T1563 | Remote Service Session Hijacking |
Comments
This diagnostic statement provides protections for production environments. Measures such as network segmentation and access control reduce the attack surface, restrict movement by adversaries, and protect critical assets and data from compromise.

Comments
This diagnostic statement protects against Remote Service Session Hijacking through the use of hardened access control policies, secure defaults, password complexity requirements, multifactor authentication requirements, and removal of terminated accounts.

| PR.PS-01.08 | End-user device protection | Mitigates | T1563 | Remote Service Session Hijacking |
Comments
This diagnostic statement protects against Remote Service Session Hijacking through the use of limiting access to resources to only authorized devices, management of personal computing devices, network intrusion prevention, and the use of antimalware.
