  System for Cross-domain Identity Management (SCIM) is an open standard protocol for automating the exchange of user identity information between identity providers and service providers. SCIM streamlines user provisioning, deprovisioning, and synchronization processes in cloud-based applications and services. It defines a set of RESTful APIs for creating, updating, querying, and deleting user identities and their associated attributes across different systems. SCIM helps organizations improve efficiency, reduce manual intervention, and enhance security by ensuring consistent identity management practices across multiple platforms and services. It simplifies identity lifecycle management and enables seamless integration between identity management systems and cloud-based applications, enhancing overall security and productivity. Learn fast and easy. Networking and Security and cocepts made simple for everyone to remeber it for long time.

What is a cloud firewall? A firewall offering in cloud infrastructure from the firewall vendors. Few vendors already have a cloud infra built across and offer their firewall from the cloud service edges. Some traditional firewall vendors also offer their firewall instance which we can install in the cloud availability zone of our choice. The basic idea would be if we are unwilling to purchase a firewall, we can take cloud firewall as a service and tunnel all the traffic to cloud  firewall for filtering our traffic.   

From my perspective, having observed numerous operation teams and being a part of various networking operation teams, whether dealing with voice, data, or transmission, I strongly believe that operation teams should take ownership of specific devices. This sense of ownership fosters a greater sense of responsibility. Currently, most operation teams work in shifts, with tickets assigned to individuals who strive to resolve them. This model effectively addresses many challenges such as managing personnel, shifts, and ensuring everyone gets an opportunity to work in different shifts, promoting rotation and prioritization of tickets. However, there is a significant challenge with this approach—no one is fully accountable for a particular region, set of customers, or even devices. Consequently, there is a lack of ownership, making it more challenging. Typically, agents are solely focused on resolving their tickets, moving on to the next one, and avoiding escalations and just complete their

Arbitrary code refers to a code which an attacker can run once he has access to a OS or Hardware. Arbitrary is added when the attacker can run any or random code on a system. With this a attacker can trigger a problem that already exists, modify information within a program, load different code, or install a problem to run later. If the vulnerability allows this code execution we should consider it with high severity as the chances once breach has occured is numerous. 

CUG stands for closed user group, this is a group configuration that limits access to the group members. Where in a CUG group can subscribe to call each other within the group. The group will be a subset of users that have been grouped to use certain SWIFT services and products in a defined context. In the data world CUG would be a group which carry the same privileges, for example access to certain pages, devices or folders. 

 A stub area is an area in OSPF which when configured does not accept routing updates from outside its autonomous system.
