Practice 02: Security operations

Security is a continuous practice, not a quarterly project.

The most common failure isn't missing tools. It's tools set up by someone who left, alerts going to an inbox nobody reads, and no plan for 6pm on a Friday. This practice removes those failure modes.

Watched 24/7. Planned. Rehearsed.

  • People on watch
  • Rehearsed incident plans
  • Evidence for insurers

What the practice covers

Six functions, run together.

Detection without response is noise. Response without detection is hope.

Detection and response

Devices, identity and email, watched around the clock.

  • Guardz
  • SentinelOne
  • 24/7

Security operations check

Eight signs someone's actually watching.

Tick what's true today. Each gap is a window an attacker could use.

Tick what's true for your business today. If you're not sure, leave it unticked.

Where you stand

8 gaps to close.

  • Someone watches alerts around the clockAttacks don't wait for business hours.
  • A device can be isolated in minutesSpeed decides how far an attacker gets.
  • Risky sign-ins are challengedStolen passwords alone shouldn't get in.
  • Email is filtered and authenticatedMost attacks still start in an inbox.
  • Critical updates go on fastExploited flaws are now the top way in.
  • There's a written incident planFriday at 6pm is not the time to write it.
  • The plan has been rehearsedA plan nobody's practised won't hold.
  • Leadership gets a security reportInsurers and boards ask for evidence.

Why it matters

The best result is the incident report you never write.

Australian small businesses face the same attacks as big companies, with a fraction of the people to respond. Shared security operations gives you continuous watch, written playbooks and rehearsed response as a service.

Insurers and larger customers now want evidence of how security actually runs, not just controls on paper. This practice produces that evidence as part of the work.

A real incident

Business email compromise at a regional construction client.

Late on a Friday afternoon, an attacker got a project administrator's password through credential reuse. The sign-in tripped Conditional Access, the risk level was raised automatically and MFA was forced. The attacker got no further.

The investigation found inbox rules set up earlier during reconnaissance. Those were removed, every session was revoked and the password reset through a hardened flow. The finance team was told directly which invoice numbers the attacker had been preparing to redirect.

From first detection to fixed: 47 minutes. It was written up, reviewed at the next monthly meeting, and turned into a tighter sign-in risk policy across our other clients.

Outcome: no financial loss and no customer impact. The same detections stopped two more reconnaissance attempts on that tenant in the next 30 days. Client anonymised.

How we take it on

From blind spots to watched.

  1. Step 1Assess

    What's covered and what isn't.

  2. Step 2Deploy

    Detection, email security, identity rules.

  3. Step 3Plan

    Incident playbooks, rehearsed.

  4. Step 4Report

    Quarterly, for leadership.

Questions

What people ask about security operations.

What does security operations include?

Detection and response on devices, identity and email, email security, patching of critical flaws, written and rehearsed incident plans, and vCISO advice for boards, insurers and tenders.

Who watches the alerts?

Our detection and response runs on Guardz and SentinelOne, with people reviewing alerts around the clock. When something's confirmed malicious, the device is isolated and sessions are revoked.

What about email?

Check Point email security filters inbound mail, and we set up SPF, DKIM and DMARC on your domain so attackers can't easily send as you.

Does this help with insurance?

Yes. Insurers ask about MFA, patching, backups and incident plans. This practice produces that evidence as part of the work.
