Pc Emergency recommends for all business owners taking the following actions to help defend against the latest ransomware attacks and network abuse attempts :
1. Enable multi-factor authentication (MFA), where possible, for anyone required to access internal networks, including external collaborators and partners.
2. Have a strong password policy in place for everyone required to access your network.
3. Decommission and/or upgrade any end-of-life operating systems and applications.
4. Review and install appropriate security applications on all computers.
5. Regularly review and install the latest software updates on all computers.
6. Lockdown remote desktop RDP access with static Local Area Network (LAN) rules, via a group policy or using access control lists.
7. Implement segregation for any network access, including for LANs (or consider using virtual LANs), and where necessary use hardware/software/access control lists
Continuously review domain accounts and computers, removing any that are unused or not needed.
8. Review firewall configurations and only whitelist traffic intended for known destinations.
9. Limit the use of admin accounts by different users as this encourages credential sharing that can introduce many other security vulnerabilities.
