Malware is inevitable. The key is to isolate malware, limit its affect over your organization and users, and remediate it quickly. To reduce the impact of malware attacks, consider these 4 steps:
1. Implement a data recovery solution.
To minimize the damage malware can cause, implemented a trustworthy plan for removing all traces of the attack. Implement automatic backups for each system. Backups should include all of the information required to fully restore the system, including the OS, software, and data. All systems should be updated at least weekly, with critical systems backed up at least daily.
2. Limit and validate administrator access.
Protect and validate admin accounts on devices to prevent malware from cracking an administrative password and gaining deeper access to a machine. All administrator passwords should be robust and follow FDCC standards.
3. Scrutinize data movement.
Implement systems to track data movement within the organization. Are packets being sent to and from devices that they shouldn’t? Tracking anomalies will help your team spot and quarantine malware quickly, minimizing the damage that they can cause.
4. Add multi-layer boundary defenses.
Control the flow of traffic (and malware) through the network by implementing borders. Create a mult-layered defense by utilizing firewalls, proxies, DMZ perimeter networks, and other network tools.
