Guardians of the Net: An Intro to Cyber Security

Welcome to the expansive world of the internet; a system of interconnected networks that, while providing us with infinite possibilities, also pose unique challenges to information security. In today's digital era, with masses of sensitive data in circulation, we need capable guardians to defend this complex virtual landscape. If you're a prospective or existing student curious about Cyber Security, you've come to the right place!

What is Cyber Security?

Cyber Security, or informational technology security, is the practice of protecting systems, networks, and programs from digital attacks. Its main purpose is to prevent unauthorized exploitation of systems and data. With the invent of the internet, the onus now falls on these guardians to safeguard our virtual ecosystem from potential threats.

Why is Cyber Security Important?

The increasing dependency on internet-based technology has amplified the rate of cybercrimes. Whether it's financial transactions, healthcare records, or personal messages, most data now exists online. This sensitive information, if unprotected, can be exploited, leading to financial losses or even damage to one's reputation. A strong Cyber Security infrastructure helps prevent this.

The Four Pillars of Cyber Security

Cyber Security isn't a single solution, rather, it's composed of various components. There are four basic pillars of Cyber Security: Network Security, Application Security, Information Security, and Disaster Recovery. Each pillar uniquely contributes to the protection of our online environment.

1. Network Security

Network security is about protecting your network, both hardware and software, from intruders. Whether it's malicious attackers or opportunistic malware, network security tools and systems help ward off these threats.

2. Application Security

Application security refers to the software and hardware mechanisms that guard against external threats that can be introduced in the development stage of an application. From secure coding to security testing, app security shields the application from potential vulnerabilities.

3. Information Security

Information security protects both raw and meaningful data from unauthorized access, use, disclosure, disruption, or destruction. It ensures that data is preserved, secure and accessible to authorized personnel when needed.

4. Disaster Recovery

Disaster recovery involves creating a strategy that helps recover or protect a network in case of a disaster. This can involve data backups, recovery strategies and continuous monitoring to ensure minimal data loss and swift recovery.

Where Do I Start With Cyber Security?

There's a plethora of specialised courses available for those interested in Cyber Security. Many universities offer programs on Cyber Security that explore various aspects of this field. An aptitude for problem-solving and an interest in technology usually forms a solid foundation for basic understanding in this field.

Conclusion

With our lives more connected and digitized than ever before, the need for fortified network security has never been more critical. Initiating a career in Cyber Security not only offers a challenging, ever-evolving field but you also become a member of the noble guild of guardians, safeguarding our virtual world. As daunting as it may sound, remember, every expert was once a beginner.
