Unfortunately, legacy security solutions require organizations to allow access to a broad range of IP addresses, port ranges and protocols in order to use SaaS and other modern apps that use dynamic IPs and ports. The principle of least privilege is all about providing the minimum amount of privilege possible for users to get their work done. The benefits of PoLP for modern applications Safeguards against human error that can happen through mistake, malice or negligence.Improves operational performance with reductions in system downtime that might otherwise occur as a result of a breach, malware spread or incompatibility issues between applications.The principle of least privilege also stops lateral network movement that can launch an attack against other connected devices by limiting malware to the entry point. Reduces malware propagation by not allowing users to install unauthorized applications.Minimizes the attack surface, diminishing avenues a malicious actor can use to access sensitive data or carry out an attack by protecting superuser and administrator privileges.What Are the Benefits of the Principle of Least Privilege? The principle of least privilege strikes a balance between usability and security to safeguard critical data and systems by minimizing the attack surface, limiting cyberattacks, enhancing operational performance and reducing the impact of human error. The principle of least privilege is an important information security construct for organizations operating in today’s hybrid workplace to help protect them from cyberattacks and the financial, data and reputational losses that follow when ransomware, malware and other malicious threats impact their operations. Why Is the Principle of Least Privilege Important? Video Description: Kumar Ramachandran, senior vice president of Prisma SASE, explains the principle of least privilege within ZTNA 2.0. The principle of least privilege as executed within ZTNA 2.0 eliminates the need for administrators to think about the network architecture or low-level network constructs such as FQDN, ports or protocols, enabling fine-grained access control for comprehensive least-privileged access. This includes modern communication and collaboration applications that use dynamic ports. Within ZTNA 2.0, the principle of least privilege means the information technology system can dynamically identify users, devices, applications and application functions a user or entity accesses, regardless of the IP address, protocol or port an application uses. Without incorporating the principle of least privilege, organizations create over-privileged users or entities that increase the potential for breaches and misuse of critical systems and data. The principle of least privilege works by limiting the accessible data, resources, applications and application functions to only that which a user or entity requires to execute their specific task or workflow. How does the principle of least privilege (PoLP) work? ![]() The principle of least privilege within ZTNA 2.0 eliminates the need for administrators to think about network constructs and enables fine-grained access control to implement comprehensive least-privileged access. Within a ZTNA 2.0 framework, the principle of least privilege provides the ability to accurately identify applications and specific application functions across any and all ports and protocols, including dynamic ports, regardless of the IP address or fully qualified domain name (FQDN) an application uses. The principle of least privilege is also a fundamental pillar of zero trust network access (ZTNA) 2.0. Organizations that follow the principle of least privilege can improve their security posture by significantly reducing their attack surface and risk of malware spread. The principle of least privilege (PoLP) is an information security concept which maintains that a user or entity should only have access to the specific data, resources and applications needed to complete a required task. ![]()
