Cyber attacks keep growing in scale and cost.
The global average breach now reaches USD 4.88 million—a 10 % jump in a single year.

Use the checklist below to close the biggest gaps before they close you.

 


1. Multi-Factor Authentication (MFA)

 

Why it matters

More than 99.9 % of breached accounts had no MFA.

Action steps

  • Turn on MFA for email, VPN, and admin portals.

  • Issue hardware tokens for critical roles.

  • Review sign-in logs weekly and lock idle accounts.

 


2. Regular Security Audits

 

Why it matters

Audits reveal outdated software and compliance gaps long before attackers do.

Action steps

  • Scan all assets each quarter with automated tools.

  • Map results to NIST SP 800-53 controls for clear priorities.

  • Fix high-risk items within 30 days.

 


3. Employee Cybersecurity Training

 

People click. Training stops the click from killing the company.

Action steps

  • Run phishing drills every month.

  • Teach safe data handling for remote work.

  • Reward fast reporting of suspicious emails.

 


4. Data Encryption Everywhere

 

Encrypt data in transit and at rest so stolen files stay unreadable.

Action steps

  • Enforce TLS 1.3 on all public sites.

  • Turn on full-disk encryption for laptops and phones.

  • Track keys in a dedicated vault.

 


5. Advanced Endpoint Protection

 

Endpoints start most breaches.

Action steps

  • Deploy one unified endpoint platform (EPP + EDR).

  • Patch agent software weekly.

  • Isolate any device that shows unusual behavior until cleared.

 


6. Network Segmentation

Stop malware from roaming.

Action steps

  • Split guest Wi-Fi from internal VLANs.

  • Place payment systems in their own subnet.

  • Use micro-segmentation for cloud workloads.

 


7. Timely Patching

 

Attackers exploit known bugs first.

Action steps

  • Enable automatic updates where possible.

  • Patch critical CVEs within 72 hours.

  • Keep a live asset inventory to avoid missed devices.

 


8. Incident Response Plan

 

A written plan cuts breach costs by up to 58 %

Action steps

  • Define roles: lead, comms, legal, IT, vendor reps.

  • Keep contact list offline.

  • Run tabletop drills twice a year.

 


9. Next-Generation Firewall + IPS

 

Layered filtering blocks malicious traffic in real time.

Action steps

  • Enable deep packet inspection.

  • Feed threat intel feeds into the firewall.

  • Log everything; review alerts daily.

 


10. Zero Trust Architecture

 

Trust nothing, verify everything.

Action steps

  • Enforce least-privilege access with IAM.

  • Monitor every session for risky behavior.

  • Re-authenticate users after context changes (new device, location).

 


11. Backups & Disaster Recovery

 

Daily, tested backups keep ransomware from holding you hostage.

Action steps

  • Run encrypted backups every night.

  • Store one copy offline.

  • Test full restore each quarter.

 


12. Continuous Monitoring & Threat Intelligence

 

Organizations that pair AI with monitoring cut breach costs by USD 2.22 million on average. 

Action steps

  • Feed logs into a SIEM for real-time alerts.

  • Add behavioral analytics to spot insider misuse.

  • Subscribe to industry threat feeds and block indicators at the edge.

 


Business Gains From This Checklist

 

Payoff Result
Fewer incidents Less downtime, lower legal cost
Stronger trust Customers stay and refer others
Compliance ready Regulators see active risk management
Sharper ops Teams fix issues before they break revenue

 


What’s Next in Cyber Defense

 

  • AI-assisted SOC tools cut incident resolution times by ≈30 % in live trials. 

  • Quantum-safe encryption pilots start in finance and government.

  • Zero-trust rollouts accelerate as new mandates take effect in the EU and US.

Stay alert; adapt quickly.

 


FAQs

 

Which controls should a small firm start with?
MFA, staff training, and quarterly scans give the fastest risk drop for the lowest cost.

How often should we back up?
Daily. Test restores every 90 days.

Does zero trust slow users?
Clear policies and single-sign-on keep friction low while blocking lateral movement.
