Final answer:
According to Charles Pfleeger, an information system is secure when it performs its intended functions without unintended actions. Ensuring the security of information systems is critical for maintaining private information and the integrity of organizations and the national financial system. Enhanced security measures are essential for protecting against data breaches and maintaining online privacy and security.
Step-by-step explanation:
According to Charles Pfleeger, an information system is secure when it does what it is intended to do and nothing else. Security in information systems is a crucial concern given the need for individuals to maintain the privacy of their personal, financial, and medical data when engaging with various organizations. For businesses and governments alike, protecting this information against unauthorized access, such as hacking attempts, and ensuring the integrity of operations and national security are paramount.
Organizations face significant challenges in preventing data breaches, which can lead to identity theft and undermine the stability of business operations and the financial system. During incidents like the 2008-2009 financial crisis, we've seen how critical the integrity of the financial system is and the consequences when it is compromised.
Consequently, implementing increased security measures, like two-factor authentication, implementing stronger passwords, and ongoing education to safeguard against scams, are essential components in enhancing online privacy and security. For companies and governments, strengthening website protections is vital to prevent unauthorized access and maintain trust with clients and citizens.
