Common Mistakes on IT Security Analyst Resumes

⚠Saying 'ensured security' without specifics - Vague claims are worthless. Name the framework, count the findings, show the reduction.
⚠Missing compliance framework names - NIST, SOC 2, PCI-DSS, HIPAA are keywords. Omitting them means ATS filters may skip you.
⚠Not showing alert volumes or triage speed - Security analysts process high volumes. Show weekly alert counts and resolution speed.
⚠Listing tools without context - 'Splunk' alone tells nothing. 'Reduced false positives by 60% using Splunk correlation rules' does.
⚠Forgetting the human side of security - Training, awareness programs, and phishing simulations show you understand the full threat surface.
