The primary role of an IT security analyst is to protect an organization's information and technology assets from cyber threats. They analyze security measures, assess vulnerabilities, and implement strategies to mitigate risks, such as intrusion detection systems, firewalls, and encryption technologies. Security analysts monitor networks for suspicious activities and investigate potential breaches, ensuring compliance with industry regulations and best practices. They also work on developing incident response plans and conduct regular security training to educate employees about security protocols, ultimately safeguarding sensitive information from data breaches and cyber attacks.
