5 Steps to Help You Recover From a Cyber Attack

June 6, 2024

No matter how many security measures you have in place, there's always a slight risk that someone might breach your defenses. No system is entirely invincible. It's like having the most advanced lock on your front door... sure, it'll keep most burglars out, but if someone really wants to get in, they'll find a way.

So, how do you plan for a cyber attack if you don't know what you're expecting or when you're expecting it?

Good news: It's easier than you might think. To assist you in creating your own recovery strategy, we've divided the process into 5 stages. Adhere to these, and you can be confident that even in the worst-case scenario, you and your team will know how to respond to prevent your business from suffering damage and disruption... and save you from the ultimate migraine.

Planning for a Cyber Attack: 5 Essential Steps

1. Assess the Damage

When a cyber attack occurs, the first step is to assess the extent of the damage. This involves identifying affected systems, compromised data, and potential vulnerabilities. Here's what you need to do:

• Isolate the Incident: Immediately disconnect affected systems from the network to prevent further spread. This minimizes the impact and limits the attacker's access.
• Gather Information: Investigate the attack thoroughly. Collect logs, analyze network traffic, and identify the attack vector (how the attackers got in), e.g., phishing, malware, or unauthorized access.
• Evaluate Impact: Determine the severity of the breach. Consider factors like data loss, service disruption, and financial implications.

2. Contain the Breach

Once you understand the damage, focus on containment:

• Quarantine Systems: Isolate compromised systems to prevent lateral movement. Disable affected accounts and services.
• Patch Vulnerabilities: Address the root cause. Apply security patches, update software, and fix misconfigurations.
• Change Credentials: Reset passwords for affected accounts. Implement multi-factor authentication (MFA) where possible.

3. Restore Systems and Data

After containment, it's time to restore normal operations:

• Data Recovery: Restore data from backups. Ensure backups are secure and up-to-date.
• System Rebuild: Rebuild compromised systems using clean images. Verify their integrity before reconnecting to the network.
• Test Restored Systems: Validate that restored systems function correctly and are free from malware.

4. Learn and Adapt

Use the incident as a learning opportunity:

• Post-Incident Review: Conduct a thorough review. Identify gaps in security controls and incident response procedures.
• Lessons Learned: Document lessons from the incident. Share knowledge with your team to improve future responses.
• Continuous Improvement: Regularly update security policies, train employees, and enhance monitoring capabilities.

5. Develop an Incident Response Plan (BEFORE You Need It)

Don't wait for an attack to create an incident response plan:

• Preparation: Define roles, responsibilities, and communication channels. Establish clear escalation paths.
• Scenarios: Create response scenarios tailored to your organization. Consider different attack types and their impact.
• Testing and Drills: Regularly test the plan through tabletop exercises and simulations. Ensure everyone knows their role.

Bonus Step 6: Partner with a Trusted IT Support Provider

Developing a cyber security culture in your business is important, but sometimes you need expert help. That's where partnering with an IT support provider (like us) can make all the difference.

Perhaps the most significant benefit of working with an IT support provider is the peace of mind that comes with knowing your business is in good hands. With a trusted partner by your side, you can rest easy knowing that your systems, data, and reputation are protected against cyber threats. You can focus on running your business confidently, knowing that your cyber security needs are being taken care of by professionals with your best interests at heart.
