try this

private void ProtectSection(string sectionName,
                                   string provider)
    {
        Configuration config =
            WebConfigurationManager.
                OpenWebConfiguration(Request.ApplicationPath);

        ConfigurationSection section =
                     config.GetSection(sectionName);

        if (section != null &&
                  !section.SectionInformation.IsProtected)
        {
            section.SectionInformation.ProtectSection(provider);
            config.Save();
        }
    }
