In this article we will talk about Common Threats to the LAN, and in previous article we already discussed about COMMON USER THREATS AND VULNERABILITIES.
The local area network (LAN) is a collection of devices interconnected using cables or airwaves. The LAN Domain requires strong security and access controls since users can access the organization’s systems, applications, and data from the LAN domain.
Threats to the LAN
The following pose a threat to the LAN:
- Unauthorized LAN access – wiring closets, data centers, and computer room must remain secure
- Unauthorized access to systems, applications, and data
- Network operating system software vulnerabilities
- Network operating system updates
- Unauthorized access by rogue users on wireless networks
- Exploits of data in-transit
- LAN servers with different hardware or operating systems – managing and troubleshooting servers becomes more difficult with varied configurations
- Unauthorized network probing and port scanning
- Misconfigured firewall
Organizations can implement various measures to manage threats to the local area network:
- Secure wiring closets, data centers, and computer rooms. Deny access to anyone without the proper credentials.
- Define strict access control policies, standards, procedures, and guidelines.
- Restrict access privileges for specific folders and files based on need.
- Require passphrases or authentication for wireless networks.
- Implement encryption between devices and wireless networks to maintain confidentiality.
- Implement LAN server configuration standards.
- Conduct post-configuration penetration tests.
- Disable ping and port scanning.
