In the present document was planned to design a new branch type as network solution for Mipymes enterprise with this the idea is allow remote connectivity to all partners until they are able to connect to their physical network. One of the reasons about why this project was created as a study focus, to provide continuity of their commercial activity for this kind of companies in the tertiary economic sector, all of them dedicated to the trade of electronic parts and equipment in Bogota when facing networks conditions from internal and external factors. Some big factors are present inside of MiPymes enterprises, which present some networking vulnerabilities, located in the shell two ( OSI model ), potential mitigations were detected and threats also were notified, all this features suppose all this is in order to put in consideration the creation for a VPN solution remote access as solution proposed as a design guide with GRE tunneling an IPsec security for MiPymes enterprise under consideration study, this will help to ensure their constantly commercial activity. These vulnerabilities were classified taking into account some few concepts located int to ISO standard globalization institute such as ISO 27001:2013 standards, which are able to define guidelines and requirements to establish and Information Security Management System (SGSI in Spanish ) and some other concepts as consideration, like ISO 27002:2013 which explain objects and controls in order to avoid vulnerabilities into the system,also you can see ISO 31000 standard which determinates guidelines for risk management, among others which provide the content and guidelines for the construction of a risk analysis matrix based on the MAGERIT methodology. Security Analysis was carried out on devices, which allowed the proposed to be offered logical network design where the main reference element is the main equipment supports the VPN system, in our case will be the RV320 certified by CISCO. Just to realize about this device meets the design requirement demanded by the company achieving a remote access VPN service represented by means on the software called Packet Tracert support tool, as a complete configuration of network with parameters associated with VLAN In DHCP also remote access based con IPSec security.
