Network Segmentation and Segregation
Segmenting and segregating your office network is key to stopping threats. Network segmentation divides a network into smaller parts. This gives better control over traffic and boosts security7. Microsegmentation uses VLANs and access control lists to make smaller, safer zones. It makes managing the network easier and stronger against attacks7.
Physical and Virtual Separation of Networks
Physical segmentation splits networks into physical parts with firewalls. It’s good for security but can be complex and expensive7. Logical segmentation is more common and cost-effective. It uses VLANs or network addressing for flexible, manageable sections7.
Internal segmentation lets organizations segment assets across locations. It monitors trust levels and adjusts security policies7. Intent-based segmentation combines traditional methods with zero-trust. It manages security with an architecture that adapts to needs7.
The zero-trust model is a “never trust, always verify” approach. It continuously checks access without making it hard for users. This improves security in changing networks7. Identity and access management (IAM) solutions protect data and manage user access. They provide roles and access levels for security and flexibility7. Network access control (NAC) solutions manage various devices on the network. They enforce BYOD policies and IoT device accommodations7.
Network segmentation reduces attack surfaces and stops lateral movement attacks. It also improves performance7. It prevents malware spread, enforces least privilege access, and enhances threat inspection and containment7. It also reduces congestion, which is great for services like online gaming and videoconferencing7. Monitoring and response benefits include easier traffic monitoring, activity detection, and event logging7.
NIST says network segmentation and segregation are key for protecting Industrial Control Systems (ICS)8. Most OT organizations use network segmentation in their cybersecurity strategy8. However, Network Access Control (NAC) systems might not see all devices, especially OT and IoT8.
Armis finds and profiles every device, giving details like make, model, and IP address8. The Armis platform automates network segmentation based on policy. It can block or quarantine devices based on behavior and attributes8. Using Armis offers full device visibility, continuous tracking, vulnerability analysis, and automated policy enforcement87.
Hardening Network Infrastructure Devices
Network devices like routers, firewalls, and switches are key for all network communications. They are also a big target for hackers because of their important role. To keep these devices safe, it’s vital to use strong security measures9.
One key step is to make sure these devices are set up securely. This means turning off services you don’t need, using strong passwords, and keeping the software up to date. These steps help a lot in keeping your office’s data and work safe910.
Another important thing is to separate different parts of your network. This makes it harder for hackers to spread their attacks. You can do this with VLANs and ACLs9.
- Use strong login systems, like 802.1X NAC, to check who and what gets on your network10.
- Keep an eye on your network for any odd behavior or rule breaks9.
