About IT Security

IT Security refers to the process of protecting computer networks, hardware, and software from unauthorised access. IT Security professionals are responsible for protecting digital assets and monitoring systems to ensure they are safe from threats. If a threat is detected or a cybersecurity attack occurs, these professionals must take steps to minimise damage and restore security to the affected device, network or system.

　　As society’s reliance on technology grows and hackers become more advanced, IT Security only grows in importance. Government agencies, large corporations and small businesses alike require the protection provided by talented IT Security professionals.

　　

Is IT Security right for me?

IT Security professionals are creative problem solvers and solution-oriented people. They love a challenge and have a keen eye for detail. They should also have a passion for technology, always keeping on top of the latest developments to ensure they can anticipate and respond to evolving IT Security threats.

　　Most IT Security professionals work in office environments while some are able to work remotely. Due to the unpredictable nature of IT Security attacks, you may have to respond to threats at odd hours. This might involve tackling threats in the middle of the night from home or even travelling to the office to work directly on the affected devices or systems.

　　

IT Security study options and costs

　　Because IT Security is an emerging field, there are no strict prerequisites in terms of degrees. Many IT Security professionals transitioned from other IT-related roles, maybe picking up a certification or two before making the move. If you do choose to pursue an IT degree, you can expect to pay around AUD$30,000 a year in Australia for a Bachelor’s degree or USD$18,000 a year in the US for an Associate’s degree.

　　To stay on top of evolving threats, it’s also important to brush up on your certifications every now and then. Some popular certifications include Certified Information Systems Security Professional (CISSP), CompTIA Security+ and Certified Ethical Hacker (CEH).

　　

Future outlook

IT Security will continue to see immense growth as technology continues to evolve and cybersecurity attacks become more sophisticated. With a cybersecurity attack occurring every 39 seconds, it’s no surprise IT Security professionals are in such high demand at the moment. In fact, there are currently 2.39 million cybersecurity positions open around the world and some IT Security jobs are set to see 33% growth by 2030!

　　

Career pathways for IT Security graduates

　　

Information Security Analyst

　　Information security analysts are responsible for defending networks, putting up firewalls and encryptions to minimise breaches and audit systems for any suspicious activity. You’ll also be responsible for implementing best IT Security practices throughout your organisation, ensuring the organisation continually responds to challenges and evolves accordingly.

　　

Penetration Tester

　　Penetration testers or ethical hackers are employed to test system vulnerabilities, just like a potential hacker would. By doing so, they’re able to expose flaws and recommend solutions. Penetration testers also develop new penetration tools to ensure organisations stay one step ahead of malicious hackers.

　　

Security Consultant

　　Security consultants are all-rounders when it comes to cybersecurity, being hired to evaluate threats and provide solutions. You’ll design and implement security protocols, policies and plans for your clients, endeavouring to cover all possible security threats. You may also need to train staff to recognise and defend against threats.

　　

Computer Forensics Analyst

　　Forensics analysts deal with cybercrime after the fact, working with organisations and law enforcement agencies to investigate digital crimes. This might include pursuing data trails, analysing mobile phone usage and recovering compromised files. You may also be required to present your findings in court.

　　

Cryptographer

　　Cryptographers use algorithms and ciphers to encrypt data, elevating the security of computer and IT systems. They may also decipher algorithms and text to decrypt information as well as analyse existing encryption systems to identify vulnerabilities. By working in accordance with industry standards, cryptographers ensure organisations are able to transmit data in a highly secure manner.
