When cyber-attacks hit, the ensuing chaos isn’t only the result of trying to get systems back online. Piecing together what actually happened can send you into just as much of a tailspin. Small to medium-sized businesses (SMBs) find themselves facing painful questions: How did attackers get in? What data was accessed? Are they truly gone, or just hiding?
The forensic investigation alone can cost in the range of £4,000 to £12,000, depending on factors like how many (and what kind of) devices were affected. For Essex businesses, this can put professional investigations completely out of the question. And without proper tools, you’re essentially flying blind through your response. After all the drained resources and extended downtime, you’re still left vulnerable to repeat attacks – because the root cause remains undiscovered.
What Is an Incident Management Strategy?
It’s 7:30 on a Monday morning. You’ve just settled in with your first coffee when your phone rings. Your IT manager sounds panicked. Someone clicked a suspicious email link on Friday, and now critical systems are behaving strangely. Customer data might be compromised. But the bigger problem? No one knows exactly what happened, how far the attackers got, or whether they’re still lurking in your network.
An incident management strategy is your organisation’s game plan for answering those questions. Think of it as your cyber fire drill: a structured approach to identifying, containing, and eliminating threats before they can cause significant damage.
Implementing a proper incident management strategy means your business is prepared to act swiftly when security alerts trigger, rather than scrambling to figure out what to do in the midst of an attack.
What Makes an Incident Management Strategy Effective?
The strongest incident management strategies for businesses share three key characteristics:
- Thorough Planning: Effective strategies aren’t created on the fly. They’re carefully mapped out, considering various attack scenarios and defining clear response protocols for each.
- Clear Roles and Responsibilities: Everyone knows exactly what they’re responsible for during an incident. From your IT team to senior management, each person understands their part in the response effort.
- Regular Reviews and Updates: Cyber threats evolve constantly, and your strategy needs to keep pace. Regular testing, reviews, and updates ensure your approach remains effective against emerging threats.
Where Does Microsoft Azure Sentinel Fit In?
Azure Sentinel is Microsoft’s cloud-native Security Information and Event Management (SIEM) platform that lets you better respond to (and prevent) security incidents. Essentially, Sentinel is designed to reduce the average time it takes your IT department to identify and resolve cyber events through enhanced investigation.
5 Steps for Responding to Cyber Threats with Sentinel
Let’s revisit that nightmarish Monday morning and walk through how Azure Sentinel could help at each phase of incident response:
Step 1: Triage
When a security alert triggers, every second counts. During this critical first phase, you can use Sentinel to:
- Collect and correlate security logs, alerts, and telemetry data from sources across your entire digital estate
- Use AI to distinguish real threats from false positives
- Prioritise incidents based on severity so you focus on what matters most
- Provide visual investigation graphs that show you exactly how an attack unfolded
This means your business can quickly determine which threats require immediate attention and which can be addressed later – a crucial capability when resources are limited.
Step 2: Preparation
We’re jumping a little out of order here, but in an ideal scenario you wouldn’t even reach the point of needing to triage.
Being prepared before an incident occurs is half the battle in effective incident management strategies for businesses. If you get the right mechanisms in place early on, potential threats can be dealt with before they actually pose a problem.
Sentinel helps by:
- Providing security posture insights to identify vulnerabilities before attackers exploit them
- Enabling proactive threat hunting to identify hidden threats
- Creating custom alerts, threat indicators, and detection rules tailored to your business risks
- Setting up automated playbooks for common security scenarios
Working with experienced Microsoft Azure providers in Essex can help you configure these preparatory measures to match your specific business needs and risk profile.
Step 3: Remediation
When a threat is confirmed, Sentinel then springs into action:
- Automatically containing threats by isolating affected endpoints or disabling compromised accounts
- Providing Jupyter Notebooks, advanced analysis tools that analyse logs, forensics, and attack patterns to help you understand complex threats
- Correlating related alerts to show the full scope of an attack
This automated response capability is particularly valuable if you’re an SMB without a large security team, as it allows for rapid containment even outside of business hours.
Step 4: Eradication
Threat neutralised; it’s time to make sure it never comes back. To this end, Sentinel offers forensic investigation tools to determine the root causes. These include:
- Tracking of all your compromised assets (affected users, IPs, and devices) to ensure nothing is missed
- Automated remediation workflows (like revoking credentials and removing malware) to restore systems to a secure state
For businesses prioritising cyber security in Essex, this comprehensive approach ensures threats are fully eliminated – not just temporarily patched.
Step 5: Post-Incident Review
Learning from incidents is how your security posture improves over time. Sentinel supports this with:
- Detailed post-incident reports and customisable dashboards that let you analyse trends, attack vectors, and response effectiveness
- Metrics to track detection and response times
- Tools to update your detection rules and playbooks based on lessons learnt
- Continuous monitoring and intelligence feedback to prevent similar incidents
Instead of leaving you at a loss, each event becomes an opportunity to further strengthen your defences, creating a cycle of always-improving cyber security.
