The entry point into the SOC is usually as a Tier 1 Analyst, often referred to as a Security Analyst or Incident Responder.

Responsibilities include -

Monitoring security tools: As a Tier 1 Analyst, your primary task is to keep an eye on various security tools like SIEMs (Security Information and Event Management), intrusion detection systems (IDS), and firewalls, looking for any signs of malicious activity.

Initial triage: In the event of an alert, you'll be the first responder, responsible for analyzing the alerts, gathering additional data, and determining the severity and potential impact of the incident.

Incident logging and documentation: Accurate and detailed documentation is paramount. You'll be meticulously documenting every incident, the steps taken, and the outcomes for future analysis and potential escalation.

Following playbooks: Tier 1 analysts often work within predefined processes and playbooks. You'll be following established procedures to respond to common security events and escalate to Tier 2 when necessary.

Skills required -

Basic networking fundamentals: Understanding fundamental networking concepts like TCP/IP, DNS, firewalls, and common ports is essential.

Operating systems knowledge: Familiarity with major operating systems like Windows and Linux, including basic command-line skills, is crucial.

Security concepts: You'll need a solid understanding of basic security concepts like malware, phishing, intrusion detection, and common attack vectors.

Strong analytical skills: Being able to analyze alerts, sift through log data, and identify patterns is key to success as a Tier 1 analyst.

How to land a Tier 1 role -

Relevant education: While not always mandatory, a bachelor's degree in cybersecurity, computer science, or a related field can give you an edge when looking for a SOC role.

Security certifications: Industry-recognized certifications like CompTIA Security+, Cisco CCNA Security, or GIAC Security Essentials can demonstrate your knowledge.

Hands-on experience: Gain practical experience by setting up a home lab, participating in online cybersecurity challenges (e.g., TryHackMe, Hack The Box), or contributing to open-source security projects.

After gaining valuable experience and expanding your skillset as a Tier 1 Analyst, you'll be well-positioned to advance to the role of a Tier 2 Analyst, often called a Security Engineer or Incident Handler.

Responsibilities include -

Deep dive investigations: You'll be responsible for conducting in-depth investigations of escalated security incidents, going beyond the initial triage performed by Tier 1.

Threat hunting: Proactively hunting for malicious activity that may have bypassed existing security controls is a key responsibility.

Malware analysis: You may be involved in analyzing malware samples to understand their behavior, capabilities, and potential impact.

Incident response plan development: Tier 2 analysts often contribute to improving incident response plans, developing new playbooks, and refining existing processes.

Mentoring: Sharing your knowledge and experience by mentoring and guiding Tier 1 analysts is a common aspect of this role.

Skills required -

Advanced network security: Deepen your understanding of network security concepts, including firewalls, intrusion detection/prevention systems, VPNs, and network segmentation.

Security tools expertise: Mastering advanced security tools such as SIEMs, endpoint detection and response (EDR) systems, and Security Orchestration, Automation, and Response (SOAR) platforms is crucial.

Scripting & automation: Knowledge of scripting languages like Python or PowerShell enables you to automate tasks, effectively analyze data, and develop custom security tools.

Threat intelligence: Develop an understanding of threat intelligence sources and techniques to proactively identify and mitigate emerging threats.

Communication & collaboration: Effectively communicating technical information to both technical and non-technical audiences is important.

Transitioning from Tier 1 to Tier 2 -

Seek continuous learning: Expand your knowledge base by pursuing advanced security certifications like CySA+, CASP+, or GCIH.

Develop specialized skills: Focus on developing expertise in areas like malware analysis, threat intelligence, or incident response, which are highly valued in Tier 2 roles.

Network & collaborate: Attend security conferences, participate in online communities, and network with other security professionals to stay updated on industry trends and best practices.

Showcase your skills: Create a professional portfolio showcasing your skills, projects, and accomplishments. Be prepared to articulate your experience during job interviews.
