What is IAM?

Identity and Access Management (IAM) is a framework of business processes, policies and technologies that facilitates the management of electronic or digital identities. It encompasses the creation, maintenance, and management of user profiles and their corresponding identity data within a system. The purpose of IAM is to ensure that the right individuals access the right resources at the right times for the right reasons.

Definition and Purpose

IAM systems assign every user a distinct digital identity with permissions tailored to the user’s role, compliance needs, and other factors. This way, IAM ensures that only authorized users can access the resources they need while blocking unauthorized access and activities.

The goal of IAM is to strike a balance between keeping important data and resources inaccessible to most but still accessible to some. It makes it possible to set controls that grant secure access to employees and devices while making it difficult or impossible for outsiders to get through.

Core Elements

The four main components of IAM include Authentication, Authorization, Administration, and Auditing and Reporting.

1. Authentication: This process actively verifies the identity of employees or users by requesting their unique identifiers and necessary credentials to prove the authenticity of each user.
2. Authorization: This is the act of granting access to tools and resources. It creates the boundary and jurisdiction where the user can operate.
3. Administration: This component manages users’ accounts, groups, permissions, and password policies. It monitors the creation and modification of users’ accounts.
4. Auditing and Reporting: This deals with examining, recording, and adequately reporting users’ access logs and all security-related activities within the system.

IAM in Different Sectors

IAM is crucial for securing access to digital resources, encompassing devices, applications, and data across various platforms. It applies to mobile devices, electronic tools, storage rooms, IoT devices, etc.

In the workplace, IAM solutions can streamline access control in complex environments with remote and hybrid workforces and a mix of legacy on-prem systems and newer cloud-based apps and services.

IAM also plays a vital role in regulatory compliance. Standards like GDPR, PCI-DSS and SOX require strict policies around who can access data and for what purposes. IAM systems allow companies to set and enforce formal access control policies that meet those standards.

What is SIEM?

Security Information and Event Management (SIEM) is a solution that combines security information management (SIM) and security event management (SEM) functions into one security management system. It helps organizations detect, analyze, and respond to security threats before they harm business operations by collecting event log data from a range of sources, identifying activity that deviates from the norm with real-time analysis, and taking appropriate action.

Definition and Purpose

The core purpose of SIEM is to provide organizations with visibility into activity within their network so they can respond swiftly to potential cyberattacks and meet compliance requirements. SIEM technology collects log and security data from computers, network devices, and applications on the network to enable alerting, archiving, and reporting.

By aggregating relevant data from multiple sources, identifying deviations from the norm, and taking appropriate action, SIEM systems help detect external and internal threats, monitor activities of privileged users, monitor server and database resource access, correlate user activity across systems, provide compliance reporting, and support incident response.

Core Elements

The core capabilities of SIEM technology include:

1. Data aggregation: SIEM systems gather vast amounts of data in one place, organize it, and determine if it shows signs of a threat, attack, or breach.
2. Event correlation: The data is sorted to identify relationships and patterns to quickly detect and respond to potential threats.
3. Incident monitoring and response: SIEM technology monitors security incidents across an organization’s network and provides alerts and audits of all activity related to an incident.

SIEM in Different Sectors

SIEM is routinely cited as a basic best practice by every regulatory standard and its absence has been regularly shown as a glaring weakness in every data breach post mortem. It plays a vital role in various sectors for securing access to digital resources, encompassing devices, applications, and data across platforms.

In the workplace, SIEM solutions can streamline access control in complex environments with remote and hybrid workforces and a mix of legacy on-prem systems and newer cloud-based apps and services. SIEM also supports compliance reporting for standards like HIPAA, PCI/DSS, SOX, FERPA, and HITECH.
