Requirements & Skills
Day in the Life
The daily routine of an Information Security Analyst begins with a thorough check of the SIEM dashboard and EDR tools to identify any alerts generated outside of business hours. After a daily standup meeting with the infrastructure team, the analyst focuses on deep-dive investigations of vulnerabilities detected in automated scans, prioritizing patches and guiding developers on secure coding practices. In the afternoon, they often participate in designing governance policies, answering security questionnaires for corporate clients, or planning controlled phishing simulation campaigns to train employees. In the event of an incident, they immediately pivot to forensic investigation to contain the threat and mitigate risk.
