Information Security Analyst
O*NET-SOC: 15-1212.00
Plans, implements, upgrades, and monitors security measures to protect an organization's computer networks and information systems from cyberattacks, data breaches, and unauthorized access.
About this Role
Information security analysts protect computer networks and data from cyber threats by designing, monitoring, and improving security systems. They spend much of their day reviewing logs and alerts from firewalls, intrusion-detection tools, and security dashboards, then investigating suspicious activity such as failed login attempts, unusual traffic spikes, or malware signatures. They configure security controls like access rules, multi-factor authentication, and encryption settings, and often recommend changes to software, configurations, or user habits to reduce risk. Analysts also conduct vulnerability scans, penetration-testing reports, or security audits, then prioritize and track fixes before attackers can exploit them. In the event of a breach, they help coordinate incident response, preserve evidence, and document what happened so the organization can recover and strengthen its defenses. This role suits people who enjoy problem-solving, paying close attention to details, and staying up-to-date with new threats and tools. The work is rewarding when analysts prevent a major attack or help an organization recover quickly, but it can be stressful due to constant pressure, odd-hour incidents, and the need to balance security with usability for other teams.
