The security protocol IPsec is used in the LTE network to achieve a securecommunication from prying eyes. However, the use of IPsec is optional bythe LTE standard. Whether or not to use the IPsec thus becomes a securitydecision that each operator has to make after having considered applicablerisks and anticipated costs. It is also important to consider the OperationalExpenditure (OPEX) for deploying, operating, and maintaining the IPsecinstallation. One important factor that can aect OPEX is usability. Forthis reason understanding the usability properties of a system can help toidentify improvements that can reduce OPEX.This study mainly focused on investigating the challenges and also investigateswhether poor usability was a contributing factor for deploymentchallenges of IPsec in the LTE infrastructure. Additionally, this study alsofocused on prerequisite knowledge for an individual in order to ensure thecorrect deployment of IPsec in the LTE network.Cognitive Walkthrough and Heuristic Evaluation usability methods wereused in this study. By using these methods, several usability issues related toIPsec conguring components like documentation, the MO structure, anda used tool were identied. It was also identied that each componenthad rooms for improvements, especially for documentation which can signicantly aid in the deployment of IPsec. Moreover, in order to smoothlydeploy IPsec in the LTE network, it is important to have beforehand knowledgeof conguring components used to deploy IPsec.
