CyberSecurity Article – 9 (The 7 Pillars of Zero Trust Model -  Strong & Effective Security Strategy Based on “Never Trust, Always Verify” Principle) There have been multiple variations of the Zero Trust model , and some models may have more or fewer pillars with regards to Zero Trust . Here I would like to emphasize on the 7 pillars of the Zero Trust model , as defined by National Institute of Standards and Technology (NIST) , which are comprehensive set of principles that are designed to help organizations building a strong and effective security strategy. The model is based on the principle of "never trust, always verify" which means that no user or device is trusted by default  and every access request must be verified and authorized before access is granted. These 7 pillars are a framework that provides a clear and concise approach to implement the Zero Trust model which covers the entire spectrum of security  from identifying and protecting asset...

  End User Security Awareness | A Chain Cannot be Stronger More Than Its Weakest Link One of the familiar phrases " A chain is only as strong as its weakest link " means that the strength of a System or Organization is only as strong as its weakest element . In other words, a System or Organization is only as secure as its weakest security control. In the context of Cybersecurity , I am trying to emphasize on the importance of Identifying and Addressing vulnerabilities in a system . A single weak link in a cybersecurity system could Compromise the Entire System , regardless of the strength of other security controls . For example, if a company has strong firewalls and intrusion detection systems but fails to educate employees about phishing scams , a single employee falling for a phishing scam could compromise the entire system . Hence, User education and awareness play a crucial role in preventing cyber-attacks  by educating users about potential cyber threats...
