What is SD-WAN? A Smarter Approach to Wide Area Network Management SD-WAN (Software-Defined Wide Area Network) is a software-based technology designed to simplify and optimize the management of wide area networks. Unlike traditional WAN architectures, SD-WAN enables intelligent control of traffic flow, improves bandwidth utilization, and enhances overall network performance. [...]
Overview
Privileged Access and Account Management (PAM) refers to a set of cybersecurity practices that control, monitor, and secure access to critical systems and sensitive data within an organization. These practices are essential for protecting high-value accounts such as administrators, IT operators, and system integrators—users who typically have elevated permissions and are often targeted in cyberattacks.
Key Components
Access Control
Role-Based Access Control (RBAC) ensures users can only access resources necessary for their job responsibilities. Excessive privileges are removed to minimize exposure.
Privileged Access Management (PAM)
PAM solutions manage and secure privileged credentials through password vaults, session monitoring, approval workflows, and audit logs. They prevent misuse and ensure traceability of every privileged session.
Multi-Factor Authentication (MFA)
Privileged accounts require stronger verification. In addition to passwords, access must be confirmed via a secondary factor such as a mobile authenticator, SMS code, or hardware token.
User Behavior Monitoring
All privileged activities are continuously logged and analyzed for anomalies. Suspicious behavior—such as unusual login times or access to unauthorized systems—can trigger real-time alerts.
Principle of Least Privilege
Users should be granted only the minimum level of access required to perform their duties. This principle reduces lateral movement and privilege escalation risks during an attack.
Access Reviews and Recertification
Access permissions should be reviewed regularly to reflect role changes, employee offboarding, or organizational restructuring. Unused or outdated privileges must be promptly revoked.
Secure Password Management
Privileged credentials must be strong, frequently rotated, and stored in encrypted vaults. Storing credentials in unprotected files or personal devices should be strictly prohibited.
Conclusion
Privileged Access and Account Management is a critical element in modern enterprise security strategies. By enforcing robust access control, real-time monitoring, and detailed auditing, organizations can drastically reduce the risk of data breaches, insider threats, and compliance violations.
