Privileged Access Management
Privileged access management, called PAM, protects the accounts that hold the most power in a cloud environment. Administrators, root users, and automation tools can change settings, read all data, and delete entire systems. Attackers target these accounts first, so organizations guard them with extra layers.
The Bank Vault Analogy
A bank teller opens a cash drawer all day. Only a few managers can open the vault, and they need two keys, a witness, and a written log. Privileged accounts deserve vault-level care. Daily accounts handle routine work, and powerful accounts require stronger proof and closer watching.
What Counts as Privileged Access
- Root or owner accounts of a cloud subscription
- Database administrator accounts
- Service accounts that run applications
- API keys with write or delete rights
- Emergency break-glass accounts
Why These Accounts Matter
One compromised administrator account can turn a small incident into a full breach. The attacker disables logging, copies databases, and creates hidden users. Reducing the number of powerful accounts and watching them closely cuts that risk sharply.
Core PAM Practices
Just-in-Time Access
Staff request elevated rights only when a task requires them. The rights expire after a set time, often one hour. Standing administrator access disappears.
Credential Vaulting
A secure vault stores passwords and keys. Engineers check out a credential, the vault rotates it after use, and nobody memorizes or shares it.
Session Recording
The system records what happens during a privileged session. Reviewers replay the session if something looks wrong.
Approval Workflows
A second person approves high-risk requests, such as access to production databases.
How Just-in-Time Access Flows
Engineer --> Request admin rights (reason + duration)
|
v
Manager approves
|
v
PAM system grants temporary role (60 minutes)
|
v
Session recorded --> Rights expire automatically
Standing Access Versus Just-in-Time Access
| Feature | Standing Access | Just-in-Time Access |
|---|---|---|
| Rights available | All day, every day | Only during approved windows |
| Attack surface | Large | Small |
| Audit trail | Weak | Clear reason and approver |
| Effort for staff | Low | Slightly higher |
Real-World Example: A Midnight Fix
A database slows down at midnight. An engineer needs administrator rights to repair it. She submits a request that names the ticket number. The on-call manager approves within minutes, and the vault grants a one-hour role. She completes the repair, the system captures the session, and the role vanishes. A reviewer reads the recording the next morning and confirms every command matched the ticket.
Protecting Service Accounts and Keys
Machines hold privileges as well. Applications often store keys in code or configuration files, and attackers search public repositories for them. Store machine credentials in a secrets vault, rotate them on a schedule, and limit each key to one task.
The Break-Glass Account
A break-glass account provides emergency access when normal login systems fail. Store its password in a sealed, monitored location. Alert the security team the moment anyone uses it. Test it twice a year to confirm it works.
Key Takeaways
PAM limits who holds power, when they hold it, and how closely the organization watches. Just-in-time rights, vaulted credentials, and recorded sessions shrink the damage any single account can cause.
