Online networks have many threats regarding security. The threats are targeting agency networks, private networks or other networks via gaining access to or changing essential information. Less secure networks deliver authorization to the users to access records in a network. Communication managers need powerful police forces to prevent access, misuse or alteration of secure network information. Small businesses or small businesses use firewalls, antibiotics or anti-spam software to protect the network, but do not provide sufficient network protection. Security in the corporate network is an important part of network protection due to the most common hacker goals. A private network is a reliable way of communicating with various business units and communicating with internal networks. Internet Protocol Security (IPsec) Virtual Private Network (VPN) is one of the most powerful security tools in the field of recording and security options. This is the safest and most secure option available in the Private Network store as a combination of two or more networks in remote areas. The goal of this research is to integrate VPN Services and establish IPsec protocols for small business security. The study is based on the networks of National College of business administration & economics (NCBA&E BWP) and its campuses by using the Cisco routers for a secure and private communication interchange between them. The result shows that IPsec VPN is an appropriate way of communication for Small and Medium-Sized Enterprises (SMEs).
