Information Security

What is information security?

Information security refers to technologies and practices that protect data that is stored on computers and other devices (such as mobile phones and PDAs) or transmitted over networks. Information security prevents individuals who do not have authorization from accessing, using, destroying, modifying, or disrupting confidential or sensitive data.

Why does my organization need information security?

Information security is critical for organizations of all sizes and in all sectors-business, government, healthcare, and education. When there is a breach in information security, confidential information about customers, finances, or intellectual property can fall into the wrong hands-a competitor or a criminal, for example. The possible consequences of such breaches include law suits, harm to a company's brand and credibility, financial losses, and even bankruptcy. Information security is also extremely important for safeguarding the privacy of individuals.

How does information security work?

Information security means different things to different people and organizations. For large enterprises, information security involves protecting networks and systems and implementing a security risk management strategy that prioritizes actions taken to minimize exposure to threats. A similar approach is taken for mid-size businesses that are interested in streamlining information security management because they often lack dedicated security resources. For small businesses, information security solutions include protection against spam, spyware, phishing, Trojans, and other common exploits. And, for individuals, information security means installing anti-virus, anti-spam, and firewall software on their computers to protect what they value and minimize concerns about identity theft and loss of privacy.

Conclusion: Information security is a wise investment for home users, small businesses, medium businesses, and global enterprises.
