Cyber Security can involve:
Software (Pen Testing, Identifying server vulnerabilities using software scans)
There are also roles identifying fraudulent activity - check out ‘fraud analyst’ roles with retailers, insurance companies, banks, etc. You’ll typically be reviewing online transactions for risky behavior.
You can also look into AML (Anti-Money Laundering) areas also to help identify wrongdoing and mitigate risk.
All in all, several areas are covered under the Cyber Security term. I’d check for some of the roles I’ve listed and determine what interests you most and then review a few job descriptions online to see the qualifications and skills companies are looking for in order to find the best fit!
It's great to know you have an interest in cyber security because it is a great way to use your skills and it is still a profession that is in high demand.
Although your job will vary according to which company you end up working for, I will outline some of the duties that may be expected of a cybersecurity professional.
You would monitor your company's network traffic and protect it from any loss, theft or issues. If something of suspect happens, you will be expected to investigate it in real time. You would also compose an incident report about it. You'd have to install security software like firewalls and encryption. You would examine the system for weaknesses and fix them. You'd also have to know how to come up with solutions for the best protection of the company's network. You would also conduct research about security threats, do risk assessments and do penetration tests.
I imagine that your day to day work would vary based on the type of company you would work for. A non-profit organization would be very different from a bank. It may be an interesting experience to shadow people working in a few different companies to see how it goes.
I sure do hope this has helped a bit and that your pursuit in this field is a successful one !
