6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Mean Time to Acknowledge (MTTA)

How quickly you pick up a critical security alert from the moment it's generated.

Target · < 15 minutes for critical alerts

A critical alert fires at 10:00 AM; you acknowledge it and start investigation by 10:12 AM, hitting the target.

Triage Accuracy

The percentage of alerts you escalate to a senior analyst or another team that turn out to be genuine security incidents, not false positives.

Target · > 95% true positives

Out of 20 escalated alerts last month, 19 were confirmed incidents. That's 95% accuracy, which is what we're aiming for.

Runbook Adherence

How consistently you follow our documented procedures and playbooks for handling common security incidents.

Target · 100% adherence for documented procedures

For a standard malware infection, you'd follow every step in the 'Malware Containment Runbook' without skipping anything, ensuring a consistent response every time.

Vulnerability Identification Rate

The number of high-severity (CVSS 9+) vulnerabilities you identify and accurately report from scheduled scans.

Target · > 10 unique high-severity vulnerabilities per month

Running a Nessus scan, you spot and correctly report 12 unique, critical vulnerabilities on our internet-facing web servers in a month.

Incident Communication Clarity

How well you explain technical security issues to non-technical teams (like IT Operations or even business users) during an incident, ensuring they understand the problem and what they need to do.

Feedback from IT teams praising clear instructions
minimal follow-up questions from stakeholders
successful and timely execution of remediation steps by other teams based on your guidance.

Proactive False Positive Reduction

Your initiative in identifying recurring false positives and proposing specific, actionable tuning recommendations to your manager or the security engineering team.

You're bringing specific examples of repeated benign alerts to weekly meetings
you're suggesting rule modifications that reduce alert volume without missing real threats
your suggestions lead to actual rule changes.

Investigation Thoroughness

The depth and completeness of your security investigations, including documenting all steps taken, evidence gathered, and conclusions reached, even for alerts that turn out to be benign.

Your incident tickets are always fully updated with detailed notes
senior analysts can easily pick up your investigation from where you left off
you're consistently identifying root causes, not just symptoms.

Knowledge Sharing & Mentorship

Your willingness to share what you've learned with new or junior team members, helping them get up to speed and understand our processes.

New joiners seek you out for advice
you're offering to do informal walkthroughs of tools or processes
you're contributing to our internal knowledge base with helpful tips and tricks.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy

Solving Complex Puzzles

You love the challenge of taking disparate pieces of information—a log entry here, a network flow there—and piecing them together to form a complete picture of what happened. It's like being a detective every day.

You spend an hour correlating a failed login attempt on a VPN with a port scan from the same IP three minutes later, then find the source IP is on a known threat intelligence list. That 'aha!' moment is what you live for.

Protecting the Organisation

You get a real kick out of knowing your work directly contributes to the security of the company, its data, and its customers. You're a digital guardian, and that feels good.

You successfully contain a ransomware attempt on a critical server, preventing a major outage and data loss. The relief and gratitude from the business is a huge motivator.

Continuous Learning & Skill Development

The threat landscape changes constantly, so you're always learning new attack techniques, tools, and defence strategies. You enjoy staying on top of the latest in cyber security.

You spend your lunch breaks reading about a new zero-day vulnerability or experimenting with a new feature in Wireshark, just because you want to understand it better.

What frustrates people

The Sisyphean Task of False Positives: Spending 60% of your day investigating alerts that turn out to be a developer running a weird test or a misconfigured marketing tool, leaving little time for genuine threat hunting. It's mentally draining.
The Remediation Black Hole: You precisely identify a critical vulnerability on a server, provide the patch instructions, and the ticket sits in the server team's queue for 90 days because their 'patching window' is full. It feels like your work isn't valued.
'Shadow IT' Surprises: Discovering a business unit has spun up a new cloud server, connected it to the corporate network, and exposed it to the internet with default credentials, completely bypassing all security reviews. It's like playing whack-a-mole.
Alert Overload During an Incident: When a real attack is happening, every system screams at once, and the challenge is filtering the critical signals from the deafening noise. It can be overwhelming.
Explaining Risk to the Uninterested: Trying to explain the danger of an N-day vulnerability to a manager who sees it as a purely technical problem and doesn't understand the potential business impact until it's too late. It's like talking to a brick wall sometimes.

What this role does not give you

A predictable 9-to-5 routine – incidents don't care about your schedule, and you might be on call or working late occasionally.
The ability to make high-level strategic decisions – you'll be executing and proposing, not setting the overall security strategy.
A role where all your work immediately goes into production – sometimes your investigations lead to dead ends, or remediation takes ages due to other priorities.

8Who you work with

Your work directly protects our digital assets and customer trust. Get it right, and we avoid costly breaches and reputational damage. Get it wrong, and the business could face significant financial losses and regulatory fines. It's not an exaggeration to say you're a key part of our defence strategy.

Inside the business

Your Manager (Senior Network Security Analyst or Lead Security Engineer)
IT Operations Team (they own the servers and infrastructure you're protecting)
System Administrators (they'll need to implement your remediation steps)
Service Desk (they'll escalate initial user-reported security issues)
Product Development (sometimes their new features cause security alerts)

Outside the business

Security Vendors (for tool support and threat intelligence)
External Auditors (they'll check our incident response processes)
Threat Intelligence Providers (we use their feeds to stay ahead)

9What you need before you start

Not a wish list. The things you would be expected to already have.

At least 2-3 years of hands-on experience in a Security Operations Centre (SOC), IT support role with security responsibilities, or a network administration role.
A solid grasp of networking fundamentals (TCP/IP, routing, switching) – you'll be looking at network traffic every day.
Demonstrable experience with at least one SIEM platform (e.g., Splunk, QRadar) for alert monitoring and basic query writing.
Experience with basic incident response procedures, even if it was following a strict runbook.
A genuine curiosity about how things break and how to fix them, especially in a digital context.

10What to practise next

Where the job is going, and what to do about it starting this week.

Advanced Behavioural Analytics

Attackers are getting stealthier, blending in with normal traffic. Relying solely on signature-based detections is no longer enough. We need to spot subtle deviations in user and network behaviour.

Baseline profiling for users and entities · Statistical anomaly detection methods · Machine learning models for threat detection · UEBA (User and Entity Behaviour Analytics) platforms

This week: Read up on the basics of UEBA and how it differs from traditional SIEM rules.
This month: Explore the behavioural analytics features in our existing SIEM/EDR platforms, even if you're just observing.
Month 2: Take an online course on basic statistical analysis or machine learning for security.
Month 3: Propose a specific use case where behavioural analytics could help us detect a threat we currently miss.

Quick win: Start looking at your existing SIEM data with a 'behavioural' lens—e.g., is a user logging in at unusual times or from unusual locations? Even without advanced tools, you can start thinking this way.

Cloud Security Posture Management (CSPM)

More and more of our infrastructure is moving to the cloud (AWS, Azure, GCP). Network security in the cloud is different from on-premise, and you'll need to understand those nuances to protect it effectively.

Cloud service models (IaaS, PaaS, SaaS) · Cloud network constructs (VPCs, Security Groups, NSGs) · Identity and Access Management (IAM) in the cloud · Cloud-native security tools

This week: Pick one cloud provider (e.g., AWS) and start learning their core networking and security concepts via free online resources.
This month: Get a free tier account and experiment with setting up a basic secure VPC and a few virtual machines.
Month 2: Take an introductory certification like AWS Certified Cloud Practitioner or Azure Fundamentals, focusing on security aspects.
Month 3: Shadow a cloud engineer or security architect to understand how they design and secure cloud environments.

Quick win: Start reading our internal documentation on our cloud environments. Even just understanding the terminology will give you a head start.

11Staying current once you are in

What people here do to keep up

Attending industry webinars and conferences (virtually or in-person) to stay current on threat trends and new technologies.
Participating in online security communities or forums (e.g., Reddit's r/cybersecurity, various Discord servers) to learn from peers.
Setting up a home lab to experiment with security tools and practice attack/defence scenarios in a safe environment.
Contributing to open-source security projects or writing blog posts about your security findings (if company policy allows, of course).
Regularly reading threat intelligence reports from reputable sources like CISA, Mandiant, or vendor-specific security blogs.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, the sheer volume of security alerts can be overwhelming. AI isn't here to replace you; it's here to make your job less tedious and more impactful. Imagine cutting down on the noise so you can focus on the actual threats.

In network security, AI can be a game-changer for sifting through mountains of logs, spotting the subtle anomalies, and even drafting your incident reports. It frees you up from the mundane, allowing you to be a true detective.

Alert Triage Assistance

Use our SOAR platform, powered by AI, to automatically enrich alerts. For a potential phishing email, it can auto-detonate links in a sandbox, check sender reputation, and query VirusTotal for attachment hashes, giving you a head start on your investigation and often closing benign tickets automatically.

Anomaly Detection Boost

Leverage User and Entity Behaviour Analytics (UEBA) modules within our SIEM. The AI learns baseline behaviour for users and servers, then flags significant deviations – like an admin logging in from a new country at 3 AM and accessing unusual files – which would be nearly impossible to spot manually in real-time.

Threat Intelligence Summaries

An AI assistant can summarise daily CISA alerts, vendor vulnerability disclosures, and relevant dark web forum chatter. It can extract key Indicators of Compromise (IOCs) and map adversary Tactics, Techniques, and Procedures (TTPs) to the MITRE ATT&CK framework, telling you which threats are most relevant to our specific tech stack, saving you hours of reading.

Incident Report Drafting

After an incident is contained, feed the timeline of events, logs, and investigation notes into an AI model. It can generate a structured first draft of the incident report, including an executive summary, technical root cause analysis, and recommended actions, ready for your human review and refinement. Less time writing, more time analysing.
