Do you feel like every click could trigger a cyberattack? You are not alone! Cybercriminals are becoming increasingly sophisticated, with more and more ingenious attack methods.
Fortunately, solutions like PAM (Privileged Access Management) exist to effectively protect your business. In this article, we’ll demystify PAM and explain why it has become essential for any organization concerned with its security.
What is PAM (Privileged Access Management) and Why is it Necessary ?
Privileged Access Management (PAM) encompasses a set of tools and processes designed to control and monitor privileged users’ access to critical systems. These users, such as network or system administrators, hold elevated rights that allow them to perform sensitive tasks.
PAM plays a key role in limiting this access, often using the “Just-in-Time” (JIT) principle, which grants temporary privileges only when necessary, thus minimizing risks.
According to Gartner, there are four main categories of PAM tools:
Privileged Account and Session Management (PASM)
At the core of PAM, PASM focuses on the centralized management of privileged accounts, whether they are administrator, service, or emergency accounts. It allows for controlling access to these accounts, recording sessions for audit and compliance purposes, and enforcing strong password policies.
Privilege Elevation and Delegation Management (PEDM)
PEDM finely manages the temporary elevation of privileges, granting users additional rights only for the duration of a specific task. This “just-in-time” approach significantly reduces the attack surface.
Secrets Management
Secrets, such as encryption keys or passwords, are critical to security. Secrets Management securely stores these pieces of information, uses them in a controlled manner, and renews them regularly.
Cloud Infrastructure EntitlementManagement (CIEM)
With the growing migration to the cloud, CIEM has become indispensable. It ensures fine-grained permission management in cloud environments, identifying and controlling excessive or unauthorized access.
Why is Privileged Account Management So Important ?
Privileged accounts are the keys that open all the doors to your information system.
They grant their holders extensive powers, enabling them to modify configurations, access sensitive data, and control the infrastructure. This is why they are a prime target for cybercriminals.

A hacker who compromises a privileged account can:
- Move laterally across your network to access other systems and sensitive data.
- Install malware to spy on your activities, steal your data, or disrupt operations.
- Take control of your systems to demand a ransom (ransomware) or launch denial-of-service (DDoS) attacks.
The Main Types of Privileged Accounts
To better understand the importance of managing privileged accounts, it’s essential to identify the different types of accounts within an organization:
- System Administrator Accounts: These control the core of your IT system; compromising them can cripple your business.
- Network Administrator Accounts: These manage network infrastructure; their compromise can lead to service disruptions and data loss.
- Developer Accounts: With access to your application’s source code, their compromise can introduce vulnerabilities.
- Service Accounts: Automated accounts performing critical tasks, whose compromise allows attackers to execute arbitrary commands.
Risks Associated with Privileged Accounts
Unprotected privileged accounts pose a persistent threat to corporate security. Poor management of these accounts can lead to catastrophic outcomes, such as:
- Compromise of Sensitive Data: Attackers can access confidential information, including customer data, trade secrets, or financial records.
- Service Interruptions: Critical systems can be brought offline, causing significant financial losses and damaging the company’s reputation.
- Infrastructure Takeover: Attackers can gain complete control of corporate systems and use them maliciously, such as launching attacks on other organizations.
Among the most common attacks targeting privileged accounts are:
- Pass-the-Hash Attacks: Stealing password hashes from privileged accounts to log into other systems.
- Privilege Escalation: Exploiting vulnerabilities to gain higher-level access than originally granted.
- Brute Force Attacks: Attempting to guess passwords by systematically trying every possible combination.
Mitigating Risks Through Robust PAM Strategies
- Pass-the-Hash attacks: Attackers steal the password hash of a privileged account to access other systems.
- Privilege escalation: Attackers exploit vulnerabilities to gain higher access rights than they initially possess.
- Brute force attacks: Attackers attempt to guess passwords by trying all possible combinations.
To mitigate these risks, implementing robust Privileged Access Management (PAM) strategies is essential, including least privilege access, regular audits, and multi-factor authentication (MFA).
How to Deploy an Effective Privileged Access Management Strategy
The deployment of a PAM solution is a complex process that requires careful planning and a methodical approach. Here are the key steps to follow:
Phase | Key Tasks | Objectives |
1. Assessment and Planning | Analyze requirements, choose the solution, define roles | Evaluate the company’s specific needs and set the foundation for deployment |
2. Discovery and Inventory | Identify accounts, classify them, document access | Gain a comprehensive overview of privileged accounts and their permissions |
3. Implementation | Integrate the solution, create policies, configure JIT access | Deploy the PAM solution and secure privileged access |
4. Monitoring and Management | Record sessions, analyze behaviors, set up alerts | Continuously monitor activities and detect anomalies |
5. Maintenance and Continuous Improvement | Apply updates, review policies, train users | Ensure the solution remains effective and adapt to evolving needs |
Key Components and Features of Privileged Access Management (PAM)
PAM solutions provide a set of essential features to secure privileged access and ensure compliance:
- Least Privilege Access: This feature restricts a user’s rights to only those necessary to perform their tasks. It significantly reduces the attack surface in case of account compromise.
- Role-Based Access Control (RBAC): RBAC assigns specific privileges to user groups based on their roles within the organization. This simplifies access management and minimizes human errors.
- Real-Time Monitoring: PAM solutions offer continuous monitoring of privileged user activities, enabling quick detection of anomalies such as unusual access or privilege escalation attempts.
- Session Recording: All actions performed by privileged users are recorded for audit and compliance purposes. These recordings can be used to trace incidents and identify those responsible.
- Password Management: PAM centralizes the management of privileged passwords, providing secure storage, automatic rotation, and strong password generation features.
- Just-in-Time (JIT) Access: JIT grants temporary privileges to a user for a specific task and automatically revokes them once the task is completed.
- Segregation of Duties (SoD): SoD ensures that no single individual has the permissions needed to perform an end-to-end critical action.
