systemctl status onepam-agent
The installer auto-registers the endpoint. Confirm the service is active.
Before OnePAM
SSH keys scattered across Oracle DB servers
# DBA team shares SSH keys to oracle@db-prod ssh-copy-id [email protected] ssh-copy-id [email protected] # Multiple DBAs have the same key — no individual accountability
Oracle Database servers accumulate shared SSH keys for the oracle user
No identity-based SSH for privileged DBA access
# SSH keys grant direct oracle/root access # No SAML/OIDC integration for SSH on OL # Ksplice patches the kernel but not SSH key sprawl
Ksplice keeps the OS patched, but SSH access remains unmanaged
SOX and PCI DSS audit gaps
# SSH logs in /var/log/secure per server # No centralized view of DBA server access # No session recording for privileged operations # SOX auditors flag SSH key management gaps
Oracle Database environments face strict compliance requirements
After OnePAM
Install OnePAM agent
curl -sSL https://onepam.com/install/YOUR_ORG_UUID | sudo bash
Works on Oracle Linux 7, 8, and 9 — compatible with Ksplice and UEK
Verify service and registration
systemctl status onepam-agent
The installer auto-registers this endpoint with your organization
SSH with corporate identity
onepam ssh orcl-prod-01.corp.com # → Redirected to Okta/Azure AD/Oracle IDCS # → MFA verified, short-lived certificate issued # → Session recorded for SOX compliance

Overview

Why Oracle Linux Servers Need Identity-Based SSH Access

Oracle Linux powers mission-critical enterprise workloads — Oracle Database, Oracle WebLogic, E-Business Suite, and Oracle Cloud Infrastructure. With Ksplice zero-downtime patching, Oracle Linux keeps kernels updated without reboots, but SSH access still relies on static keys and local accounts. DBAs, application administrators, and cloud engineers accumulate SSH keys across Oracle Linux servers that run for years in production. OnePAM adds SAML/OIDC SSO to SSH on Oracle Linux without modifying sshd configuration or disrupting Ksplice. The local agent installs with a single command and is compatible with Oracle Linux 7, 8, and 9. The gateway SSH proxy protects Oracle Linux servers without agent installation — shielding database servers from SSH zero-day vulnerabilities. Both modes enforce MFA, issue short-lived certificates, record privileged sessions, and provide the audit trails required by SOX, PCI DSS, and Oracle's own database security guidelines.

Local Agent

Install the OnePAM agent on Oracle Linux with a single command. Compatible with UEK (Unbreakable Enterprise Kernel) and Ksplice. Supports Oracle Linux 7, 8, and 9.

Gateway SSH Proxy

Deploy a OnePAM gateway to proxy SSH connections to Oracle Linux servers. No agent required. Ideal for Oracle Database Appliance, Exadata, and environments where agent installation is restricted by Oracle support policies.

SSH Security Risks

SSH Security Risks on Oracle Linux

Without identity-based SSH access, these risks threaten your servers every day.

Oracle Linux servers running Oracle Database are high-value targets — a compromised SSH session can expose terabytes of sensitive financial or customer data
UEK and RHCK kernels receive Ksplice patches, but OpenSSH vulnerabilities still require traditional patching and change control windows
SSH key sharing for the oracle and grid OS users creates unauditable privileged access to production database servers
Oracle Linux 7 servers in extended support run older OpenSSH versions that may lag behind upstream security fixes
DBAs with long-lived SSH keys retain access to Oracle Database servers long after role changes or employment ends
The Challenge

SSH Security Challenges

These are the risks organizations face with traditional SSH authentication.

Shared Oracle User Access

Multiple DBAs SSH as the oracle or grid user. Static SSH keys provide no individual accountability for database operations performed over SSH.

Ksplice Doesn't Patch SSH Keys

Ksplice provides zero-downtime kernel patching, but SSH key sprawl and orphan access are application-layer problems that Ksplice cannot address.

SOX/PCI Compliance Gaps

Oracle Database environments processing financial transactions require SOX and PCI DSS compliance — including identity-verified SSH access with session recording.

OCI and On-Premises Split

Oracle Linux runs both on Oracle Cloud Infrastructure (OCI) and on-premises. SSH access management is fragmented across cloud console and traditional key management.

Exadata/ODA Restrictions

Oracle Database Appliance and Exadata systems have strict policies about third-party agent installation. SSH security must work within Oracle's support boundaries.

DBA Offboarding Delays

When DBAs leave or change roles, their SSH keys remain on Oracle Linux database servers. Manual cleanup across RAC clusters and Data Guard environments is error-prone.

Setup Guide

How OnePAM Adds SSO to SSH on Oracle Linux

Step-by-step guide to deploying identity-based SSH access.

1

Choose Agent or Gateway Deployment

Install the OnePAM agent on Oracle Linux, or deploy a gateway SSH proxy for agentless protection of Oracle Database servers.

Agent: Run 'curl -sSL https://onepam.com/install/YOUR_ORG_UUID | sudo bash' on Oracle Linux 7+. Compatible with UEK and Ksplice. Gateway: Deploy OnePAM gateway to proxy SSH — ideal for Exadata and ODA where agent installation may be restricted.
2

Connect Your Identity Provider

Configure Okta, Azure AD, Oracle IDCS, or any SAML 2.0/OIDC provider for SSH authentication on Oracle Linux.

OnePAM supports Oracle Identity Cloud Service (IDCS) natively. IdP attributes are mapped to Oracle Linux users (oracle, grid, root) with fine-grained access policies.
3

Map IdP Groups to DBA Access

Define which IdP groups can SSH to which Oracle Linux servers, as which users, and with what sudo privileges.

Example: IdP group 'dba-prod' gets SSH as oracle user on production RAC nodes with MFA step-up. 'dba-dev' gets access to development instances. 'app-admins' get WebLogic server access.
4

SSH with Corporate Identity

DBAs and administrators SSH to Oracle Linux servers using their corporate credentials. Short-lived certificates replace shared SSH keys.

Run 'onepam ssh orcl-prod-01.corp.com'. OnePAM handles IdP authentication, issues a time-limited certificate, and maps the user to the oracle OS account based on IdP group membership.
5

Audit and Comply

Every SSH session is logged with IdP identity, MFA status, and optional keystroke recording for SOX and PCI DSS.

Compliance teams get a unified audit trail: who accessed which Oracle Linux server, as which OS user, from which device, with what MFA method. Full session recordings available for forensic analysis.
Key Benefits

Benefits of SSH SSO on Oracle Linux

What changes when you deploy identity-based SSH access.

Individual DBA Accountability

Every SSH session to Oracle Linux database servers is tied to a named corporate identity — no more shared oracle user SSH keys.

Frequently Asked Questions

SSO for SSH on Oracle Linux FAQ

Common questions about SSH SSO and zero-day protection.

Is OnePAM compatible with Oracle's UEK and Ksplice?

Yes. The OnePAM agent is fully compatible with Oracle's Unbreakable Enterprise Kernel (UEK) and Ksplice zero-downtime patching. OnePAM operates at the SSH authentication layer and does not interfere with kernel-level components.

Can OnePAM protect Exadata and Oracle Database Appliance?

Yes. The gateway SSH proxy requires no agent installation on the Exadata or ODA system. The gateway authenticates users and proxies SSH connections, keeping the appliance configuration untouched and within Oracle's support boundaries.

Does OnePAM support Oracle IDCS as an IdP?

Yes. OnePAM supports Oracle Identity Cloud Service (IDCS) as a SAML 2.0 and OIDC identity provider. This enables Oracle Linux SSH access to be authenticated through the same IDCS tenant used for Oracle Cloud applications.

How does OnePAM handle the shared oracle OS user?

OnePAM maps individual corporate identities to the oracle OS user via IdP group membership. Each DBA authenticates with their personal credentials and MFA, then receives a certificate that grants access as the oracle user. Session recordings tie every action back to the individual.

Does OnePAM meet SOX requirements for Oracle DB server access?

OnePAM provides identity-verified access logs, multi-factor authentication, session recordings, and access reviews that satisfy SOX Section 404 controls for IT general controls over database server access.

Can OnePAM work alongside Oracle Linux's built-in security features?

Yes. OnePAM coexists with Oracle Linux security features including SELinux, firewalld, and Oracle's security-hardened kernel configurations. No modifications to existing security policies are required.
