When a Tampa construction firm was hit with ransomware, their first instinct was to restore from the previous night’s backup. Had they done so, the dormant malware on their network would have instantly re-encrypted everything, wasting precious time and data. Their story highlights a critical question: what should a business do in the first 24 hours after a cyberattack? The answer is to follow a methodical plan, not your gut. This guide provides that plan, breaking down the crucial steps from containment and evidence preservation to safe data recovery, ensuring you don’t make a critical mistake when the pressure is on.
Key Takeaways
- Isolate the Threat Immediately: In the first hour, your goal is containment. Disconnect affected devices from the network and disable compromised accounts to stop the attack from spreading, but leave the machines powered on to preserve critical forensic evidence.
- Activate Your Response Team in Parallel: A cyberattack requires a two-track response. Call your IT provider for technical containment while simultaneously contacting your insurance carrier and legal counsel to handle strict notification deadlines and compliance requirements.
- Use the Attack as a Blueprint for Prevention: After recovery, shift from reactive to proactive. Perform a full security audit to find the root cause, use those findings to strengthen your defenses, and create a detailed incident response plan that you test regularly.
What Should You Do in the First Hour of a Cyberattack?
The first 60 minutes after you discover a cyberattack are the most critical. The actions you take during this golden hour can mean the difference between a contained incident and a full-blown business catastrophe. Your primary goal is to stop the bleeding by containing the threat and preventing it from spreading further across your network. While panic is a natural reaction, having a clear, step-by-step plan will help your team act decisively. These initial steps are designed to limit the damage, preserve crucial evidence for investigation, and lay the groundwork for a swift recovery.
Disconnect Compromised Devices
Your first move is to isolate any device you suspect is compromised. If you see a ransomware note on a screen or notice a computer behaving erratically, immediately disconnect it from the network. This means unplugging the ethernet cable and turning off its Wi-Fi connection. However, do not turn off the machine itself unless directed by a cybersecurity expert. Shutting down the computer can erase volatile memory (RAM) which often contains vital forensic evidence about the attacker’s activities. Isolating the device prevents malware from spreading to other workstations, servers, and critical infrastructure, effectively quarantining the threat. This single action is one of the most effective ways to contain an attack in its early stages.
Lock Down User Accounts and Access Points
Attackers rarely break in through the front door; they usually steal a key. Compromised user credentials are a primary tool for hackers to move through your network and access sensitive data. As soon as you identify a potential breach, immediately disable or reset the passwords for any associated user accounts. Pay special attention to accounts with administrative privileges, as these give an attacker widespread control. For example, if an employee’s machine is infected after clicking a phishing link, their Microsoft 365 and network accounts should be locked down until the threat is neutralized. This cuts off the attacker’s access and stops them from escalating their privileges.
Block Suspicious IP Addresses
If your team has the technical ability, blocking the attacker’s IP address at your firewall is a powerful containment step. Think of your firewall as a digital bouncer for your network. By identifying the malicious IP address sending commands or stealing data, you can instruct your firewall to block it completely. This severs the connection between the attacker and your compromised systems, preventing them from issuing more commands or exfiltrating more data. Identifying the right IP to block often requires analyzing firewall logs and network traffic, which is where having professional cybersecurity services on standby becomes invaluable. They can quickly pinpoint and block the source of the attack.
Document Everything in Real Time
While you’re taking action, create a detailed log of everything that happens. This is not the time to rely on memory. Use a separate, clean computer or even a physical notebook to record a precise timeline of events. Note when the incident was discovered, who discovered it, which systems are affected, and every action taken (like disconnecting a PC at 10:15 AM). Preserve digital evidence by saving system logs, firewall records, and security alerts. Do not wipe or re-image systems prematurely. This documentation is absolutely essential for the forensic investigation, for supporting a potential data recovery effort, and for filing a cyber insurance claim.
Who Do You Call First After a Cyberattack?
When you discover a cyberattack, your first instinct might be panic. But the actions you take and the people you call in the first hour can determine whether your business recovers quickly or faces catastrophic losses. Having a clear contact list and making calls in the right order is not just a good idea; it’s a critical part of your incident response. Your goal is to assemble your expert team immediately to contain the threat, protect evidence, and begin managing the complex legal and financial fallout. The four calls you need to make are to your IT provider, your insurance carrier, your legal counsel, and, when appropriate, law enforcement.
Your Managed IT or Cybersecurity Provider
Your first call, without a doubt, should be to your managed IT or cybersecurity provider. Think of them as the digital first responders. At IGTech365, our team is prepared to jump into action to immediately begin containing the threat and assessing the scope of the breach. An experienced IT partner will work to isolate affected systems to stop the attack from spreading, preserve crucial forensic evidence for investigation, and identify which accounts or data have been compromised. They are the ones who can technically diagnose the problem and start the hands-on work of taking your network back. Don’t try to fix things yourself; you could accidentally destroy evidence or make the problem worse.
Your Cyber Insurance Carrier
Immediately after contacting your IT team, your next call is to your cyber insurance carrier. Most policies have a strict 24- to 48-hour notification requirement, and missing this window could give the insurer grounds to deny your claim entirely. Your policy documents should list a 24/7 breach hotline; find this number now and keep it accessible. Once you report the incident, the carrier will typically assign a “breach coach,” often an attorney, to guide you through the process. They will also provide a list of approved vendors for services like digital forensics, credit monitoring, and public relations. Using unapproved vendors can also jeopardize your coverage, so this call is essential before you incur any major expenses.
Legal Counsel
While your insurance carrier may assign a breach coach, you also need to engage a lawyer who specializes in data privacy and cybersecurity. This is a critical step for navigating your legal obligations under laws like Florida’s Data Breach Notification Statute. Your attorney will advise you on who you are legally required to notify (customers, regulators) and by when. All communications about the incident should be directed through your legal counsel to protect your company under attorney-client privilege. This prevents internal emails and reports from being used against you in potential lawsuits. Your lawyer will work with your IT team and insurance carrier to create a coordinated and legally sound response strategy.
Law Enforcement and Regulatory Agencies
Your legal counsel will guide you on when and how to contact law enforcement and regulatory bodies. For many businesses, especially those in healthcare (HIPAA) or finance, reporting a breach to specific government agencies is a legal requirement with firm deadlines. For criminal matters like ransomware, you should file a report with the FBI’s Internet Crime Complaint Center (IC3). While local law enforcement may have limited resources for cybercrime, reporting to the FBI helps federal agencies track cybercriminal groups and identify larger patterns. This step is crucial for both legal compliance and contributing to the broader fight against cybercrime.
How Do You Assess the Full Scope of the Damage?
Once you’ve stopped the immediate bleeding, the next step is to figure out exactly how bad the wound is. This damage assessment is not the time for guesswork. A thorough, methodical investigation is the only way to understand the full scope of the breach, which dictates every single step you’ll take next, from recovery to legal notifications. This is where having a professional cybersecurity partner is invaluable; they have the tools and experience to quickly map out the “blast radius” and give you a clear picture of the situation.
Identify Which Systems and Data Were Compromised
Your first job is to create a map of the affected areas. You need to determine which specific systems, applications, and data sets were touched by the attacker. This means looking beyond the initial point of entry to see if the breach spread laterally across your network. Was it just one workstation, or did they get into your primary server? Did they access your cloud data in Microsoft 365?
Just as important is understanding what they did. Did they encrypt your files in a ransomware attack, or did they exfiltrate (steal) sensitive data? Knowing whether they accessed customer financial details, employee PII, or proprietary company secrets will define your legal and regulatory obligations in the coming hours and days.
Analyze the Attack Vector
To prevent the attacker from walking right back in, you have to find and lock the door they used. Analyzing the attack vector means pinpointing the exact method and vulnerability the cybercriminal exploited to gain access. Was it a convincing phishing email that an employee clicked? Was it an unpatched software vulnerability on a public-facing server? Or was it a simple case of a weak or stolen password?
Tracing the attacker’s path is a critical piece of the forensic puzzle. For example, if the entry point was a phishing link, your IT team must identify everyone who received that email to ensure other accounts aren’t also compromised. This analysis isn’t just about looking backward; it’s the first step in building a stronger defense for the future.
Use Tools to Measure Impact: SIEM, EDR, and Scanners
A proper damage assessment isn’t done by just poking around. It requires specialized tools that can see what the human eye can’t. Professionals use a combination of technologies to get a complete picture. A SIEM (Security Information and Event Management) platform helps by collecting and analyzing log data from across your network, creating a timeline of the attacker’s activity.
Meanwhile, EDR (Endpoint Detection and Response) tools on your computers and servers act like a flight recorder, showing exactly what processes were run and what files were accessed. These tools, often part of a robust Microsoft 365 security plan, are essential for tracing the breach. This forensic data is critical for understanding the full scope and for eradicating the threat completely.
Prioritize Systems Based on Business Impact
You can’t fix everything at once, so you need to be strategic. This is where a Business Impact Analysis (BIA) comes into play. A BIA helps you rank your systems and data based on their importance to your daily operations. For a law firm, the case management system is mission-critical. For a construction company, it might be the project management and accounting software.
By understanding which systems have the biggest impact on revenue and operations, you can create a prioritized recovery plan. This ensures your team focuses its efforts on getting the most essential parts of your business back online first, minimizing downtime and financial losses. This strategic approach is a core part of any effective data recovery service.
How Do You Stabilize Operations in Hours 2–12?
After the initial shock and immediate containment actions of the first hour, the next phase is about stabilizing your environment. This period, roughly from hour two to twelve, is critical for gaining control and laying the groundwork for recovery. The goal is to stop the bleeding, understand the situation without making it worse, and methodically execute your response. Rushing or making uninformed decisions here can lead to greater data loss, longer downtime, and even legal trouble. This is where having a clear, pre-defined plan and expert guidance becomes invaluable. The steps you take now will directly influence how quickly and completely your business can recover.
Activate Your Incident Response Plan
If you have an incident response plan (IRP), now is the time to execute it. This document is your playbook, designed to guide you through the chaos with clear instructions. Your plan should outline exactly who is responsible for what, how teams should communicate, and the specific steps to take. Make sure everyone knows their job and follows the protocol. Improvising under this kind of pressure often leads to mistakes. A well-crafted IRP, often developed with a cybersecurity partner, ensures a coordinated and effective response, turning panic into purposeful action. Following the plan keeps your team aligned and focused on the most important tasks.
Decide Whether to Isolate or Restore Systems
Your primary goal is to stop the attack from spreading further into your network. This requires a critical decision: which systems should you isolate, and which can you begin to restore? You need to identify all affected devices, servers, and network segments and disconnect them from the rest of your infrastructure. However, avoid the urge to simply shut everything down. Turning off a compromised machine can destroy crucial forensic evidence stored in its volatile memory. This is a technical judgment call best made with an expert. A professional can help you contain the threat without compromising the investigation or your ability to use data recovery services later.
Preserve Forensic Evidence Correctly
As you work to contain the breach, you must also act as a digital crime scene investigator. Preserving evidence is not just for learning what happened; it’s essential for legal proceedings and insurance claims. Keep a detailed, real-time log of every action your team takes. Document when the breach was discovered, which systems were affected, who was involved in the response, and what steps were taken to contain it. This record is an invaluable asset. Our team at IGTech365 is trained in forensic-safe procedures to ensure that all evidence is preserved correctly, providing a clear chain of custody that will stand up to scrutiny from insurers and legal teams.
Avoid Critical Mistakes in the First 12 Hours
In the heat of a crisis, it’s easy to make critical errors. Some of the most common mistakes include waiting too long to contain the attack, trying to fix systems without understanding the root cause, and destroying evidence by rebooting machines prematurely. Another frequent misstep is communicating about the incident before you have all the facts or without consulting your legal and insurance partners. Resisting the urge to make a quick fix is vital. Instead, rely on your incident response plan and your expert partners. Having managed IT support means you have a team to guide you away from these pitfalls and toward a sound, methodical recovery.
What Are Your Legal and Insurance Obligations?
Once you’ve started the technical containment process, you need to immediately address your legal and insurance duties. These obligations are just as time-sensitive as isolating infected systems, and mishandling them can be financially devastating. In the first 24 hours, your response must run on two parallel tracks: the technical fix and the compliance fix. This involves notifying the right people in the right order, understanding your specific industry regulations, and following the exact procedures laid out by your insurance policy.
Navigating these requirements during a crisis is incredibly stressful. As a managed cybersecurity provider with over 15 years of experience in the Tampa area, we help businesses coordinate these efforts. We work directly with your legal counsel and insurance carrier to ensure the technical evidence we preserve meets their strict requirements for claims and reporting. This integrated approach protects you from missteps that could lead to denied claims or regulatory fines down the road. The key is to act deliberately and quickly, following a clear plan for your legal and insurance communications.
Understand Data Breach Notification Timelines
The clock on legal notifications starts the moment you discover a breach, not when you have all the answers. Florida’s Information Protection Act (FIPA), for example, requires you to notify affected individuals within 30 days. Many cyber insurance policies demand even faster reporting, sometimes within 48 to 72 hours.
You must talk to a lawyer immediately to understand the specific data breach laws that apply to your situation. They will guide you on who you need to notify (customers, regulators), when you need to do it, and what information you must provide. Waiting too long to start this process can create significant legal and financial problems, regardless of how well you handle the technical recovery.
Meet Industry-Specific Compliance (HIPAA, PCI-DSS)
If your business operates in a regulated industry, you face an additional layer of rules. For healthcare organizations in Tampa, a breach of patient data is a HIPAA violation with its own strict notification requirements. Similarly, any business that processes credit cards must adhere to PCI-DSS standards. Failing to meet these industry-specific compliance requirements can result in severe penalties on top of any fines from general data breach laws.
Understanding your duties under frameworks like HIPAA or PCI-DSS before a crisis helps you tell a clear, accurate story to regulators and customers when an incident occurs. Your legal counsel and IT provider should be able to map out exactly what is required for your specific industry.
Know How Cyber Insurance Aids Recovery
If you have a cyber insurance policy, you must contact your carrier immediately. Most policies have strict rules about this; they require quick reporting and mandate that you follow specific steps. Waiting to call them is one of the biggest mistakes a business can make. Your policy is more than just a check after the fact, it’s a recovery toolkit.
Your insurer often provides a pre-approved panel of experts, including legal counsel, PR firms, and forensic investigators who are experienced in crisis response. If you hire your own team without the insurer’s consent, they may refuse to cover the costs. Treat your insurance carrier as a primary partner from the very first hour.
What Happens If You Miss a Notification Deadline?
Missing a legal or insurance notification deadline can be more costly than the cyberattack itself. The consequences are severe and multifaceted. First, waiting too long can result in the denial of the insurance claim, leaving you to pay for the entire recovery out of pocket. This includes forensic services, system restoration, legal fees, and customer credit monitoring.
Second, you will likely face significant fines from regulatory bodies for non-compliance. Finally, the delay erodes trust with your customers, who may feel you hid the incident from them. This can lead to brand damage and even class-action lawsuits. The financial and reputational risks are simply too high to ignore these critical deadlines.
How Do You Manage Communications During a Crisis?
How you communicate during and after a cyberattack is just as critical as your technical response. A well-managed communication strategy protects your reputation by building trust with your team, your customers, and your partners. The goal is to control the narrative with clear, consistent, and honest information, preventing panic and speculation from filling the void. This isn’t just about damage control; it’s a core part of your overall incident response.
Getting this right shows you are prepared and in control, even when facing a significant challenge. It involves a careful sequence: briefing your internal team first, then informing external stakeholders, all while being mindful of what you say and who says it.
Communicate Internally with Your Team
Your first audience is your internal team. Before you say anything publicly, your employees need to hear it from you. Be as transparent as possible about the situation, what you know, and what steps are being taken. This prevents rumors and ensures everyone presents a united front. Provide your team with a simple, approved statement they can use if customers or partners ask questions. A clear internal policy for crisis communication is essential for retaining trust. While your IT team or a provider like IGTech365 focuses on the technical fix, leadership must focus on keeping the team informed, calm, and aligned.
Communicate Externally with Customers and Stakeholders
Once your internal team is briefed, you need to inform your customers and other external stakeholders. Your goal is to share the news in a way that keeps impacted parties calm and informed. Don’t wait for them to hear about it from someone else. Acknowledge the incident proactively, explain that you are investigating, and outline the immediate steps you’re taking to contain it. You don’t need to have all the answers, but you do need to show you are in control. Work with your cybersecurity provider to craft a message that is accurate and reassuring without revealing sensitive operational details.
Know What Not to Say (and When)
In a crisis, what you don’t say is as important as what you do. Avoid speculating on the source of the attack, the extent of the damage, or when systems will be fully restored. Never make promises you can’t keep. It’s better to say, “We are still investigating and will provide an update by 4 PM,” than to give inaccurate information. All communications should be reviewed by your legal counsel and incident response leader to ensure message consistency and avoid admitting liability. Hasty, unvetted statements can create legal and financial problems long after the technical incident is resolved.
Designate a Spokesperson Before a Crisis
Deciding who speaks for the company should happen long before a crisis hits. Designate one or two individuals as official spokespeople and provide them with media training. This ensures your message is consistent, controlled, and delivered by a credible source. Effective incident communication demonstrates control and accountability when it matters most. This person should be the single point of contact for all media inquiries and public statements. Having this role defined is a key part of a mature incident response plan, something we help Tampa businesses develop through our IT consulting services.
How Do You Begin the Recovery Process (Hours 12–24)?
After the initial chaos of containing a cyberattack, the next 12 hours are about methodical and safe recovery. This isn’t a race. A rushed restoration can reintroduce the threat or miss the root cause, leading to another breach just days or weeks later. This phase is about rebuilding with precision, using what you’ve learned from the attack to harden your defenses. It requires a clear plan, executed in a specific order, to ensure you’re not just restoring your data but also your security posture.
For example, a Tampa-based law firm we worked with was hit by ransomware. Their first instinct was to restore everything from the previous night’s backup immediately. However, our team first ensured the network was completely clean of the malware. Had they restored right away, the dormant malware on a connected device could have re-encrypted the newly restored files within minutes. This is why the 12-to-24-hour window is less about speed and more about strategy. It involves restoring systems from clean backups, patching the vulnerability that allowed the attack, documenting every action for legal and insurance purposes, and making a calculated decision about any ransom demands.
Restore Systems Safely and in Order
You cannot restore clean data onto a dirty network. Before you begin, your IT team or provider must confirm the threat is fully neutralized and the environment is secure. Only then should you start the restoration process using clean, verified backups. This is a core component of professional data recovery services. We always recommend rebuilding compromised servers and workstations from scratch or a known-good “golden image” rather than attempting to disinfect them. Hidden malware can persist and reactivate later.
The restoration itself should follow a prioritized order. Start with mission-critical systems that are essential for business operations, like your primary accounting software or client database. Once those are stable, you can move on to less critical applications. This tiered approach gets your core functions back online faster while the full recovery continues.
Patch the Exploited Vulnerabilities
A cyberattack is a painful but effective audit of your security weaknesses. Before you bring systems back online, you must fix the hole the attacker used to get in. This isn’t optional; it’s the only way to prevent an immediate repeat performance. Your incident response team should have identified the attack vector, whether it was an unpatched firewall, a weak remote desktop password, or a successful phishing email. Now is the time to act on that intelligence.
This means applying all overdue software updates, enforcing multi-factor authentication across all accounts, and resetting all user passwords. Your cybersecurity provider can help you identify and close these gaps efficiently. Addressing the root cause turns a reactive crisis into a proactive security improvement, making your business more resilient for the future.
Complete Your Post-Incident Documentation
Throughout the crisis, you should have been keeping a detailed log. Now is the time to consolidate and complete it. Keep a detailed record of every step you take: when you found the breach, what you did, who helped, and what evidence you saved. This record is vital for legal reasons, insurance claims, and learning from the event.
Your documentation should include timestamps for every action, the person who performed it, the outcome, all communications with vendors or law enforcement, and any costs incurred. This isn’t just red tape; it’s the evidence you’ll need to file a cyber insurance claim, prove due diligence to regulators, and conduct an effective post-mortem analysis to prevent future incidents.
Avoid Paying Ransom Without Expert Guidance
If you’re facing a ransomware attack, the pressure to pay can be immense. However, you should not pay the ransom right away. First, there is no guarantee the attackers will provide a working decryption key. Second, paying them funds their criminal enterprise and marks your business as a willing target for future attacks.
Before making any decision, consult with your managed IT support provider, your legal counsel, and the FBI. These experts can help you evaluate the situation, including the viability of your backups and the specific strain of ransomware you’re dealing with. They can provide guidance based on experience with thousands of similar cases, helping you make a calculated business decision rather than an emotional one.
How Can You Prevent the Next Cyberattack?
After the immediate crisis is over, the real work begins. Surviving a cyberattack isn’t just about recovery; it’s about using the hard-won lessons to build a much stronger defense. The goal is to make sure this never happens again, or at the very least, that the impact is significantly smaller next time. This isn’t a one-time fix. It’s about shifting from a reactive mindset to a proactive security culture. The attack gave you a painful but clear roadmap of your weaknesses. Now, you can systematically turn those weaknesses into strengths. By taking deliberate steps to audit your environment, reinforce your defenses, and formalize your response plans, you can drastically reduce your risk and prepare your business for future threats.
Conduct a Post-Incident Security Audit
Once your systems are stable, your first move should be a comprehensive security audit. This goes far beyond just patching the vulnerability that caused the breach. A thorough post-incident audit acts as a complete post-mortem, examining every layer of your security to find out what went wrong, how the attackers moved through your systems, and what other weaknesses exist. The goal is to strengthen your cybersecurity posture from the ground up. This process identifies the root cause and maps out the full timeline of the incident, giving you a clear, unbiased view of your security gaps so you can prioritize fixes effectively.
Strengthen Your Endpoint, Network, and Cloud Defenses
The findings from your audit will create a punch list for reinforcing your technical defenses. This means hardening every potential entry point, including endpoints (laptops, servers), your network, and your cloud infrastructure. You might need to deploy advanced Endpoint Detection and Response (EDR) tools, upgrade to a next-generation firewall, or reconfigure your Microsoft 365 security settings. The idea is to create a layered defense where if one control fails, another is there to stop the threat. Continuous monitoring and automated testing are key to ensuring these defenses remain effective against evolving attack methods.
Build and Test Your Incident Response Playbook
If you didn’t have a formal Incident Response Plan (IRP) before the attack, you certainly need one now. If you did have one, the attack was a live-fire drill that showed you exactly where it fell short. Use this experience to build or refine a detailed incident response playbook. This document should outline specific, step-by-step actions for different attack scenarios, like ransomware or a business email compromise. Most importantly, you must test this playbook regularly through tabletop exercises with your team. This practice builds muscle memory, ensuring a faster, more coordinated, and less chaotic response during a real crisis.
Partner with a Managed Cybersecurity Provider
You don’t have to handle cybersecurity alone. For many businesses in the Tampa area, partnering with a managed security provider is the most effective way to prevent future attacks. A dedicated partner like IGTech365 provides the 24/7 monitoring, specialized expertise, and enterprise-grade tools needed to defend against modern threats. Our managed IT support services offload the day-to-day burden of security management, from patching systems to hunting for threats. This allows you to focus on running your business, confident that a team of experts is protecting your digital assets around the clock.

Frequently Asked Questions
What is the absolute first thing I should do if I suspect a cyberattack? Your first move should be to contain the threat. If you see a ransomware message or notice a computer acting strangely, immediately disconnect it from the network by unplugging its ethernet cable and turning off the Wi-Fi. It is very important that you do not turn off the computer itself. Shutting it down can erase crucial evidence from its memory that experts need to understand how the attack happened and what the attacker did.
Who are the first people I need to call, and in what order? Your first call should always be to your IT or cybersecurity provider. They are the technical first responders who can begin containing the attack and preserving evidence. Immediately after, you must call your cyber insurance carrier. Most policies have very strict notification deadlines, and missing them could result in your claim being denied. Your insurer will also connect you with critical resources, like a legal expert known as a breach coach.
What is the biggest mistake businesses make right after a breach? The most common and damaging mistake is trying to fix the problem too quickly without a full diagnosis. Many businesses rush to wipe affected machines or restore from backups before the network is fully clean. This can destroy vital forensic evidence needed for an insurance claim or legal defense, and it often fails to remove the root cause of the attack, allowing the malware to reinfect your newly restored systems.
Do I really have to call my insurance company and a lawyer right away? Yes, you absolutely do. These calls are just as time-sensitive as the technical response. Your cyber insurance policy likely has a strict 24 to 48-hour window for you to report an incident. If you miss it, they can deny your claim, leaving you to cover all recovery costs. Contacting a lawyer who specializes in data privacy protects your communications under attorney-client privilege and ensures you meet legal notification deadlines for customers and regulators.
After we recover, how do we stop this from happening again? Recovery is only half the battle. To prevent a repeat incident, you must use the attack as a lesson to strengthen your defenses. Start with a complete post-incident security audit to identify not just how the attacker got in, but all other security gaps. Use those findings to build a stronger defense by updating technology and security policies. Finally, create or refine a formal incident response plan and test it regularly with your team so everyone knows exactly what to do next time.
