• Frequent updates: Update all operating systems, firmware, and applications.
• Management of legacy systems: Create unique security protocols for unupdatable systems.
• Management of change: Create a procedure for patch testing prior to production environment deployment.
• searching for vulnerabilities: Check systems frequently for known vulnerabilities.

5. Offer Training on Security Awareness

Either your biggest weakness or your best defense may be your workforce. Spend money on thorough security awareness training:

• Frequent training sessions: Provide regular security awareness training to all staff members.
• Simulations of phishing: To test and raise staff awareness, run simulated phishing campaigns.
• Education on security policies: Make certain that every employee is aware of and complies with security policies.
• Procedures for reporting incidents: Teach staff members how to identify and report security incidents.
• Training tailored to a role: Provide customized training according to access levels and work responsibilities.

"Over 85% of data breaches are caused by human mistake. The best security control is a workforce that is well-trained."

6. Put Endpoint Security into Practice

Endpoint security is more important than ever as more devices connect to your network:

• Next-generation antivirus: Install cutting-edge endpoint defense that makes use of machine learning and behavioral analysis.
• Endpoint detection and response (EDR): Put in place systems that are able to identify and address endpoint threats.
• Encrypting devices: Encrypt every endpoint device, particularly laptops and mobile devices.
• Management of mobile devices (MDM): To secure and control mobile devices, use MDM solutions.
• Whitelisting applications: Only permit authorized apps to operate on company-owned devices.
• Controls for peripherals and USB: Limit the use of unapproved USB peripherals and devices.

7. Create a Plan for Incident Response

Even with the best precautions, security mishaps can still happen. Have a thorough incident response strategy ready:

• Procedures that are documented: Establish thorough protocols for various security issue types.
• Response group: Create a multidisciplinary team with roles and duties that are well-defined.
• Protocols for communication: Specify when and how to notify both internal and external parties about issues.
• Frequent drills: Test your response skills with simulations and tabletop exercises.
• Analysis following an incident: Perform a comprehensive analysis following each incident to enhance subsequent reactions.
• Compliance with laws and regulations: Make sure your reaction strategy takes into account all applicable legal and regulatory requirements.

8. Control the Risk of Third Parties

Your weakest link, which frequently consists of outside partners and providers, determines how strong your security is:

• Evaluations of vendor security: Prior to interacting, assess each vendor's security stance.
• Requirements for contractual security: Incorporate certain security specifications within vendor agreements.
• Frequent evaluations: Review vendor security procedures on a regular basis.
• Restricted entry: Give vendors just the bare minimum of access that is required.
