A recent briefing from the FBI’s Internet Internet Crime Complaint Center (IC3) detailed current best practices and industry standards for cyber defense. Here is a summation:

Cyber Defense Best Practices

• Backups – Regularly back up data and verify its integrity. Backups are critical in ransomware; if you are infected, backups may be the only way to recover your critical data.
• Training – Employees should be made aware of the threat of ransomware, how it is delivered, and trained on information security principles and techniques.
• Patching – All endpoints should be patched as vulnerabilities are discovered. This can be made easier through a centralized patch management system.
• Antivirus – Ensure anti-virus and anti-malware solutions are set to automatically update and that regular scans are conducted. Centrally managed is even better.
• File Permissions – If a user only needs to read specific files, they should not have write-access to those files, directories, or shares. Configure access controls with least privilege in mind.
• Macros – Disable macro scripts from Office files transmitted via email.
• Program Execution Restrictions – Implement software restriction policies or other controls to prevent the execution of programs in common ransomware locations, such as temporary folders supporting popular internet browsers, and compression/decompression programs.
• Remote Desktop Protocol – Employ best practices for use of RDP, including use of VPN, auditing your network for systems using RDP, closing unused RDP ports, applying two-factor authentication wherever possible, and logging RDP login attempts.
• Software Whitelisting – Implement application whitelisting. Only allow systems to execute programs known and permitted by security policy. This one takes careful planning.
• Virtualization – Use virtualized environments to execute operating system environments or specific programs. No physical access to servers makes hacking harder.
• Network Segmentation – Implement physical and logical separation of networks and data for different organizational units. Keep guest traffic out of your business network.
• No Saved Passwords – Require users to type information or enter a password when their system communicates with a website. Better yet use a password management tool.
