Improving Your Company’s Wired Network Security – Part 2
As covered in Part 1, due to threats from both insiders and outsiders, the security of wired networks should get more priority than wireless networks. Below covers four more basic precautions that every business should take for protecting its system and data.
Physical Security
A network’s physical security is just as important as its Internet firewall, but it is often neglected. Absent strong physical security measures, a hacker or an employee could easily compromise a network. For example, a cyber criminal could connect a wireless router into an open Ethernet port, allowing wireless access to a company’s network. Every organization should implement a security plan that prevents unauthorized building entry and network access.
Traffic Segregation via VLANs (Virtual Local Area Networks)
VLANs may be utilized to segregate a company’s network by type of traffic (VOIP, SAN, general access, and DMZ) for design or performance. Otherwise, segregation may be by user type (management, employees, and guests) for security. Dynamic assignment configuration makes a VLAN very useful. For example, a guest’s laptop may be automatically assigned to a specific VLAN, restricting its access within a network. This can be accomplished either through MAC address tagging or 802.1X authentication.
Up-to-Date Network
Confirm the installation of the latest firmware or software updates on every component of a network’s infrastructure. Ensure that the network’s computers and devices have the most current OS and driver updates. Ensure that all firewalls are active, antivirus programs are functioning and updated, and default passwords are reset.
Virtual Private Networks (VPNs) for Encryption
Encryption must be utilized to ensure network traffic security. Even if VLANs and 802.1X authentication are used, cyber criminals may still be able to access a company’s network traffic, which may include documents, e-mails, and passwords, if unencrypted. Typically, VPNs permit only authenticated remote access by using tunneling protocols and encryption techniques to prevent the disclosure of private information.
