Full-text article available at: https://doi.org/10.5120/17751-8837Enterprise Local Area Networks (ELANs) have been expanding following an increase in the number of staff which necessitates the establishment of new offices. However, the reliability and security of services provided by ELANs need to be ensured at all times to meet the expectations of users. In this paper, the network security holes existing within the ELANs were investigated. Vulnerabilities and threats were critically examined in one of the ELANs. It was observed that known vulnerabilities were still around within the network. Based on the findings, the paper suggests that all software used in the networking devices need to be updated; unneeded open ports need to be closed; cache servers and security policy need to be implemented. The suggestions will ensure the stability of the network during scaling out as the number of staff continues to grow.enELANsLocal Area NetworksEnterprise Local Area NetworksLANNetwork securityNetworking devicesNetworkSecurity policyArticle
