Each pillar works together to cover an important part of protecting data and systems, independently the pillars are defined as follows.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Confidentiality<\/h2>\n\n\n\n<p>This is in relation to preventing important or sensitive information from<br>being accessed by unwanted individuals. You may find that an organization will have varying<br>levels of scrutiny in this pillar depending on how much they value the info that is being<br>protected. An organization may also have training for those that will be working with or<br>handling important systems or documents. This training could include simple things like how to<br>make and set up strong passwords or more complex tasks for the IT department, like how to set<br>up firewalls (Hashemi-Pour &amp; Chai, 2023).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Integrity<\/h2>\n\n\n\n<p>Here the most important thing is making sure that information is not<br>improperly modified or deleted, unless done by authorized individuals. It also is important to<br>keep data accurate and trustworthy no matter whether it is being kept for long periods or being<br>moved often (NIST SP).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Availability<\/h2>\n\n\n\n<p>This the pillar focuses on making sure that data is easily accessible to authorized individuals. This means always keeping up with hardware maintenance, making sure proper updates are made, all to limit any errors that could happen (HashemiPour &amp; Chai, 2023).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How the pillars work together<\/h2>\n\n\n\n<p>While these pillars each cover only a small area of IT security, they work best when put<br>together. The CIA Triad can help guide organizations to better understand how to protect their<br>systems and data while keeping trust in that data by the workers in the organization itself.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Authentication and Authorization<\/h2>\n\n\n\n<p>Moving on to what the differences between authentication and authorization. These<br>two are related but still distinct when in an organization. When it comes to authentication, this<br>is what verifies a user\u2019s identity. This is done through things like a password or other credentials<br>to prove someone\u2019s identity. This can make authentication something that happens before any<br>authorization can take place as a system needs to know who is using it before any access can be<br>given.<\/p>\n\n\n\n<p>When authorization comes into play, it takes what user is trying to access its data or<br>system and then determines based on that, what the user is allowed to do. Such as only letting<br>members of a financial department edit or delete files related to the companies income or<br>losses.<br><br>Working together authentication and authorization can make sure that data is secure<br>and controlled by stopping any unwanted individuals from accessing important information. By<br>making this prosses hard to bypass it can limit any damage that a hacker would normally be able<br>to do without these safeguards in place (Kosinski, 2025).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">References<\/h2>\n\n\n\n<p>Confidentiality, integrity, and availability: The CIA triad.
