As a junior cyber security analyst, your responsibilities involve identifying and preventing cyber threats to a company or other organization. Your duties may include establishing threat plans and protocols, maintaining data, monitoring security network access, performing tests and risk analysis, reviewing security alerts and taking steps to protect the information, updating and maintaining a firewall, and recommending security tools and countermeasures to your superiors. Most junior cyber security analyst positions are entry-level, so you usually work under the supervision of a senior cyber security analyst until you have gained the necessary skills and experience to work on your own.
