Whenever you write a message, open an account or visit a site, your information goes through local and international networks. Although this type of connectivity simplifies and accelerates life, it puts users at risk of cyber dangers that are becoming more and more dangerous.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Network security is a practice that involves securing networks, network devices, and data against unauthorized access, misuse or cyberattacks. With the more sophisticated cyber dangers, learning how to safeguard yourself is no longer a matter of choice but a must-have tool to all individuals who utilize the internet.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The article will give a comprehensive description of network security, the types of threats, and how to be safe on the Internet.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Network_Security_is\"><\/span><strong>What Network Security is?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Network security is a term used to describe the combination of technologies, policies, procedures and practices aimed at securing computer networks and data against attacks, damage or unauthorized access.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cybersecurity awareness is based on understanding the basic network security concepts. The concepts assist users and organisations in safeguarding confidential data, as well as ensuring safe online spaces.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Network security is centered around three basic principles:<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"CIA_Triad_Principles\"><\/span><strong>CIA Triad Principles<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Confidentiality<\/strong>: Makes sure that sensitive data is accessed by authorized personnel. This will avoid hackers or unauthorized users accessing confidential information.<\/li>\n\n\n\n<li><strong>Integrity<\/strong>: Assures that data is not distorted, compromised or corrupted when being transmitted or stored.<\/li>\n\n\n\n<li><strong>Availability<\/strong>: Guarantees the availability of systems, services and data when required by authorized users.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These three concepts are commonly known as the CIA Triad which is a fundamental model in the field of cybersecurity.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_Importance_of_Network_Security\"><\/span><strong>The Importance of Network Security.<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">With the growing reliance on digital systems, network security is becoming more and more important.
