How Technology Managers Can Prevent Lateral Movement with Firewalls
Lateral movement is a silent threat. It occurs when attackers move within a network after breaching its perimeter. They can access valuable data without being detected immediately. It's vital to understand how firewalls play a key role in stopping this hidden danger.
Understanding Lateral Movement
For technology managers, stopping lateral movement should be a high priority. Once inside your network, cybercriminals exploit internal systems to reach sensitive data or cause harm. Traditional security measures focus mostly on stopping attackers from coming in. However, they don't always address what happens once an attacker is already inside.
Firewalls: More Than Just Gatekeepers
Firewalls are more than just walls at the network's edge. They can be configured to monitor and limit internal traffic between devices. This means if an attacker gets in, the firewall can stop them from moving around inside your network.
Key Strategies for Using Firewalls:
- Network Segmentation: Firewall rules can divide your network into sections. This limits how far an attacker can go if they get in. Each section can have its own rules to control access.
- Access Controls: Define who can access what. Allow only authorized users or applications to move between network segments.
- Traffic Monitoring: Constantly watch network traffic for strange or unusual activity. Firewalls can alert you to these, giving you a chance to act fast.
Why Lateral Movement Prevention Matters
Allowing lateral movement can lead to data breaches resulting in lost revenue and damaged reputation. By using firewalls wisely, you can protect your network and its data.
