Introduction:

Adversaries no longer need to exploit software vulnerabilities; they simply log in using stolen or overprivileged identities. With machine and AI identities now outnumbering humans 109 to 1, traditional Privileged Access Management (PAM) falls short. Palo Alto Networks’ new platform, Idira, addresses this shift by introducing Zero Standing Privilege (ZSP) and agentic functionality to secure every human, machine, and autonomous identity.

Learning Objectives:

  • Understand Zero Standing Privilege and its application to human and non-human identities
  • Implement ephemeral, just-in-time access controls using native Linux and Windows tools
  • Audit and harden machine identities (API keys, service accounts, AI tokens) against modern adversary techniques

You Should Know

  1. Demystifying Zero Standing Privilege (ZSP) with Linux/Windows Commands

ZSP means no permanent privileged access exists. Instead, privileges are granted just-in-time (JIT) and revoked immediately after use. This mimics Idira’s core promise – “democratized privileged access.”

Step‑by‑step guide – Linux (JIT sudo with audit):

  1. List all users with sudo privileges (standing access):

`grep -Po ‘^sudo.+:\K.$’ /etc/group`

Remove unnecessary users with `sudo deluser username sudo`

2. Enable sudo command logging for accountability:

`echo “Defaults log_output” >> /etc/sudoers.d/custom`

  1. Implement temporary sudo via `timeout` and shell aliases: 
    alias temp-sudo='function _ts() { sudo -k; sudo -v; timeout $1 sudo "$2"; }; _ts'
Usage: temp-sudo 300 "apt update"

4. Audit historical privilege usage (Linux auth log):

`journalctl _COMM=sudo | grep -E “COMMAND|USER”`

Step‑by‑step guide – Windows (JIT with JEA and PAM):

1. Check for users with permanent Admin rights:

`net localgroup Administrators`

Remove with `net localgroup Administrators username /delete`

  1. Configure a JIT role using Just Enough Administration (JEA): 
    New-PSRoleCapabilityFile -Path .\JITMaintenance.psrc -ModulesToImport @{ ModuleName='Microsoft.PowerShell.LocalAccounts' }
Restrict to specific commands (e.g., Restart-Service)

  2. Create a temporary group membership for 30 minutes: 

    $group = [bash]"WinNT://./BackupOperators"
$user = [bash]"WinNT://./jsmith"
$group.Add($user.Path)
Start-Sleep -Seconds 1800
$group.Remove($user.Path)

  3. Enable PowerShell transcription to log all privileged sessions:

`Set-PSReadLineOption -HistorySaveStyle SaveNothing` and enforce via GPO.

  1. Securing Machine Identities: API Keys and Service Accounts

Machine identities (API keys, service account passwords, OAuth tokens) are prime targets. Idira consolidates their governance. Here’s how to harden them using native tools.

Step‑by‑step guide – API key rotation and least privilege:

  1. Discover hard‑coded secrets in code (Linux – using gitleaks): 
    wget https://github.com/gitleaks/gitleaks/releases/latest/download/gitleaks_linux_x64.tar.gz
tar -xzf gitleaks_linux_x64.tar.gz
./gitleaks detect --source . --verbose

2. Rotate AWS IAM access keys automatically (CLI):

aws iam create-access-key --user-name jenkins-sa
aws iam update-access-key --access-key-id OLD_KEY --status Inactive --user-name jenkins-sa
 Delete old key after verifying new one works
aws iam delete-access-key --access-key-id OLD_KEY --user-name jenkins-sa
  1. Apply Azure Managed Identity instead of static credentials: 
    Assign system-assigned managed identity
az vm identity assign -g MyRG -n MyVM
Grant identity access to Key Vault secret
az keyvault set-policy -n MyKV --secret-permissions get list --object-id <identity-principal-id>

4. Windows – detect overprivileged service accounts:

Get-WmiObject win32_service | Where-Object {$<em>.StartName -ne "LocalSystem" -and $</em>.StartName -ne "NT AUTHORITY\NetworkService"} | Select Name, StartName

Mitigation: Replace each service account with a Managed Service Account (MSA) or gMSA: 

New-ADServiceAccount -Name BackupSvc -DNSHostName backup.domain.com -PrincipalsAllowedToRetrieveManagedPassword "Domain Computers"
  1. Agentic Identity Hardening: Protecting AI Agents and Autonomous Systems

AI agents consume identities via API tokens, session cookies, or OAuth2 bearer tokens. Idira’s “agentic functionality” means these identities must prove their legitimacy continuously.

Step‑by‑step guide – validating and restricting AI agent tokens:

  1. Implement token binding (prevent replay) using JWT `jti` claim (Python example): 
    import jwt, redis
r = redis.Redis()
def verify_token(token):
decoded = jwt.decode(token, options={"verify_signature": True})
if r.sismember("used_jti", decoded["jti"]):
raise Exception("Replay detected")
r.sadd("used_jti", decoded["jti"])
r.expire("used_jti", 300)  5 min window

  2. Linux – enforce rate limiting on agent API endpoints (using fail2ban): 

    /etc/fail2ban/jail.local
[agent-api]
enabled = true
port = http,https
filter = agent-auth-fail
logpath = /var/log/nginx/agent_access.log
maxretry = 10
findtime = 60
bantime = 900

  3. Windows – apply OAuth2 scopes for AI service accounts (PowerShell + Azure AD): 

    $app = Get-AzureADApplication -Filter "DisplayName eq 'AI-Scraper'"
$scope = New-AzureADApplicationScope -AppId $app.AppId -ScopeName "data.read" -AdminConsentDescription "Read only"

  4. Simulate an AI agent identity attack (token exfiltration via environment variable): 

    Attacker view
ps aux | grep -i agent
cat /proc/<PID>/environ | tr '\0' '\n' | grep -i token

Hardening: Store tokens in hardware security modules (HSMs) or use systemd’s `LoadCredential` to pass secrets without env vars: 

 /etc/systemd/system/ai-agent.service
[bash]
LoadCredential=api-token:/etc/secrets/agent.token
ExecStart=/usr/bin/agent --token ${CREDENTIALS_DIRECTORY}/api-token
  1. Migrating from Legacy PAM (CyberArk) to Modern Platforms like Idira

Organisations locked into traditional PAM face identity silos. Idira promises consolidation. Here’s a practical migration playbook using open-source tools to achieve “ephemeral for all” (as one commenter said).

Step‑by‑step guide – extraction and ephemeral adoption:

  1. Export all CyberArk safe members and platforms (REST API): 
    curl -k -u "CyberArkUser:Pass" "https://cyberark.example.com/PasswordVault/api/Safes" > safes.json

2. Identify long‑standing privileged accounts (Linux script):

 Find accounts with password last set > 90 days
for user in $(getent passwd | cut -d: -f1); do
lastchange=$(chage -l $user | grep "Last password change" | awk -F': ' '{print $2}')
echo "$user $lastchange"
done | awk '{if(NR>1) print}'
  1. Replace with temporary credential broker (Teleport example – open source): 
    Install Teleport
curl https://goteleport.com/static/install.sh | bash
Configure JIT access with request workflow
tctl users add --roles=access-requestor jane

  2. Windows – convert shared admin accounts to LAPS (Local Administrator Password Solution): 

    Deploy LAPS via GPO
Import-Module AdmPwd.PS
Set-AdmPwdComputerSelfPermission -OrgUnit "OU=Workstations,DC=domain,DC=com"
Force password rotation every 30 days
Get-AdmPwdPassword -ComputerName PC01

Critical validation: Ensure no service breakage by running a shadow environment with Teleport’s `tsh proxy` for 7 days.

5. Cloud Hardening for Identity Silos Breakdown

Idira unifies identities across clouds and on‑prem. Use these commands to break identity silos in AWS, Azure, and GCP.

Step‑by‑step guide – cross‑cloud conditional access:

  1. AWS – enforce MFA for all IAM users (policy snippet): 
    {
"Effect": "Deny",
"Action": "",
"Resource": "",
"Condition": {"BoolIfExists": {"aws:MultiFactorAuthPresent": false}}
}

2. Azure – block legacy authentication (PowerShell):

$caPolicy = New-AzureADConditionalAccessPolicy -DisplayName "Block Legacy Auth" -State "enabled" -Conditions @{ ClientAppTypes = @("exchangeActiveSync", "other") } -GrantControls @{ Operator = "OR"; BuiltInControls = @("block") }
  1. GCP – enforce workforce identity federation (no static keys): 
    gcloud iam workload-identity-pools create idira-pool --location=global
gcloud iam workload-identity-pools providers create-aws aws-provider --workload-identity-pool=idira-pool

4. Audit cross‑cloud privilege escalations (using `cloudsplaining`):

pip install cloudsplaining
cloudsplaining download --profile aws-prod
cloudsplaining scan --input-file aws-prod.json --output findings/

Mitigation: Enable Azure AD Identity Governance access reviews for all cloud roles monthly: 

New-AzureADAccessReview -DisplayName "Cloud Admin Review" -StartDateTime "2026-06-01" -EndDateTime "2026-06-30" -ScopeId "/" -ScopeType "DirectoryRole"

6. Vulnerability Exploitation: How Attackers Abuse Overprivileged Identities

Understanding the adversary is key. Idira’s Zero Standing Privilege directly counters these techniques.

Step‑by‑step guide – offensive simulation and detection:

  1. Linux – abuse a stale Kerberos ticket (pass‑the‑ticket): 
    Dump tickets from memory (requires root)
impacket-ticketer -nthash <KRBTGT_HASH> -domain-sid <DOMAIN_SID> -spn cifs/target.domain.com "Administrator"
export KRB5CCNAME=/tmp/ticket.ccache
smbclient //target.domain.com/C$ -k

2. Windows – enumerate overprivileged service accounts (PowerView):

. .\PowerView.ps1
Get-DomainUser -SPN | Select SamAccountName, ServicePrincipalName
 Request a service ticket for Kerberoasting
Request-SPNTicket -SPN "MSSQLSvc/sql.domain.com"
  1. Mitigation – detect anomalous token usage with Sysmon (Windows): 
    <!-- Sysmon config to log token creation -->
<EventFiltering>
<RuleGroup name="Token" groupRelation="or">
<ProcessCreate onmatch="exclude"/>
</RuleGroup>
</EventFiltering>

Install: `Sysmon64.exe -accepteula -i sysmon.xml`

  1. Linux – monitor for `sudo` abuse using auditd: 
    auditctl -w /etc/sudoers -p wa -k sudoers_change
auditctl -a always,exit -S execve -F uid=0 -k root_command
ausearch -k root_command --format text | grep "sudo"

7. Mitigation Playbook: Idira‑Style Protective Controls

Implement a complete identity security stack using open‑source and native tools to mirror Idira’s capabilities.

Step‑by‑step guide – unified identity hardening:

  1. Deploy Keycloak as a unified identity broker (centralises human + machine OIDC): 
    docker run -p 8080:8080 -e KEYCLOAK_ADMIN=admin -e KEYCLOAK_ADMIN_PASSWORD=changeit quay.io/keycloak/keycloak:latest start-dev
Create a client for machine identities with “Service Account” enabled

  2. Enable Just‑In‑Time (JIT) SSH access using `sshd` AuthorizedKeysCommand (Linux): 

    echo "AuthorizedKeysCommand /usr/local/bin/jit-authorizer" >> /etc/ssh/sshd_config
Script checks a short-lived signed token from Vault

  3. Windows – implement Privileged Access Workstations (PAWs) with AppLocker: 

    New-AppLockerPolicy -RuleType Exe -User "DOMAIN\Admins" -Action Allow -Path "C:\Windows\System32.exe"
Set-AppLockerPolicy -Policy $policy -Merge

  4. Continuous identity analytics with Wazuh SIEM (detect anomaly like impossible travel): 

    Wazuh custom rule
<rule id="100010" level="12">
<if_sid>2500</if_sid>
<field name="win.eventdata.logonType">10</field>
<field name="win.eventdata.sourceAddress" type="pcre2">!\b(US|EU|CN)\b</field>
<description>Impossible travel logon</description>
</rule>

Final validation: Run a breach simulation using `Caldera` with identity‑based plugins to test ZSP enforcement.

What Undercode Say

  • Zero Standing Privilege is no longer optional – With machine identities outnumbering humans 109:1, legacy PAM creates attack surface, not security.
  • Ephemeral access must be the default – The comment “ephemeral for allllll” captures Idira’s core shift: temporary, just‑in‑time privileges for every entity – including AI agents.
  • Identity silos are attack highways – Palo Alto Networks correctly identifies that fragmented IAM (cloud, on‑prem, CI/CD) allows lateral movement. Unity + ZSP is the answer.
  • Agentic identity introduces new risks – AI agents with overprivileged tokens can become autonomous attackers. Idira’s agentic functionality likely includes continuous authentication (step‑up or token binding).
  • Existing CyberArk customers need a roadmap – The article hints at an upgrade path. Organisations should start migrating service accounts to Managed Identities and implement JIT APIs before full platform adoption.

Analysis: The launch of Idira signals a maturation in identity security – moving from “who has access” to “who can request, prove, and lose access in real time.” Traditional PAM vendors will be forced to integrate machine identity governance and AI‑aware policies. However, the challenge will be operational complexity: implementing Zero Standing Privilege across legacy apps that expect static credentials. Early adopters should focus on high‑value targets (domain admins, cloud root accounts, CI/CD tokens) and expand outward.

Prediction

Within 24 months, identity‑based breaches will surpass software vulnerability exploits as the primary initial access vector. Platforms like Idira will force a market consolidation – standalone PAM, IGA, and CIEM products will merge into unified identity fabrics. However, adversarial AI will also evolve to abuse agentic identities through prompt injection on privileged AI assistants. The winning security model will combine zero standing privilege with behavioural AI detection – exactly where Idira’s “agentic functionality” points. Expect Microsoft and CyberArk to announce similar platforms by Q4 2026.
