The NIST Cybersecurity Framework

The NIST Cybersecurity Framework

NIST is an acronym for the National Institute of Standards and Technology at the U.S. Department of Commerce, and the NIST Cybersecurity Framework is commonly referred to as the CSF. The Framework provides a structure for private enterprises to assess and improve their ability to prevent, detect, and respond to cyber incidents.

First formulated in 2014, a recent study reported that 70% of the surveyed organizations see the NIST framework as a widespread best practice for computer security, 50% have noted that to do so requires a significant monetary investment, which is a barrier for adoption

Redshift vs. Postgres

Redshift vs. Postgres Compare Performance & Functionality Xplenty

The critical differences of Redshift vs. Postgres:
1. Table data is implemented via rows with Postgres, while Table data is implemented via columns with Redshift,
2. Indexing and Keys are handled differently by Redshift and Postgres,
3. A Clustered vs Single Node is the key architectural difference of Redshift and Postgres implementations.

This article will define, discover and compare the performance and functionality differences of both Redshift and Postgres, and how theses variances can potentially determine which choice you will make when deciding between the two when selecting a database warehouse solution to manage your critical business data.

RAID Storage Systems and how RAID is changing with SSD

RAID Storage Systems and How RAID Is Changing With SSD

RAID (Redundant Array of Independent Disks) is a method of storing the same data in different locations on multiple hard disk drives (HDD) or solid-state drives (SSD) to protect data in the event of a drive failure.

This method increases the speed of storing and accessing data while preventing data loss and unplanned downtimes – as data is shared over multiple disks, this increases the mean time between failures (MTBF). Storing data redundantly also increases fault tolerance

Post Implementation Review

Post Implementation Review Report

The objective of Post Implementation Reviews (PIRs) is to provide an independent review of the achievements of the overall project, identify project performance in key areas and generate recommendations as to how performance in future projects may be improved. The recommendations include lessons learnt in areas where improvement is warranted as well as in areas where things were done well. The report also captures any outstanding issues and follow-up actions.

Business Case Document

Business Case Document

Nearly every project needs to be approved—whether that means getting the simple go-ahead from your team or gaining the support of an executive stakeholder. You may be familiar with using a project plan or project charter to propose a new initiative and get the green light for a project. But if your proposed project represents a significant business investment, you may need to build a business case.

As Built Document

As Built Document

The basic definition of as-built documentation can be derived from its name with relative ease – it is a set of documents (either a drawing or a 3D data set) showcasing the building in question exactly how it was built. As-built documentation includes all of the current dimensions of the project’s results, from the facade to various doors, windows, cables, pipes, and more. It should also include every change made during construction without planning beforehand.

There is one main reason as-built documentation needs to exist in the first place, and it is self-explanatory. The issue here is that there is always a difference between the original project’s intent and the finished product since these projects are so massive in scale and complex. Many issues could lead to this problem – from scheduling problems and budget changes to unpredictable happenings that affect the construction process in one way or another.

Project Schedule

Project Plan

A project schedule is a timetable that shows the start and end date of all project tasks, how the tasks relate to each other and usually which team members or other resources are responsible for delivery.

It is a dynamic document that is created during initial the planning stage. The approved project schedule acts as a baseline to work to, but it is maintained and updated throughout the project as things change.

A project plan is a series of formal documents that define the execution and control stages of a project. The plan includes considerations for risk management, resource management and communications, while also addressing scope, cost and schedule baselines.
