deepsecurity

Provide a Ruby Wrapper for Trend Micro's DeepSecurity SOAP API. Also includes a command line binary dsc which exposes some of the functionality to shell scripts.

The library wraps the Deep Security Manager SOAP web service (https://<manager>:4119/webservice/Manager?WSDL) with Savon and maps the WSDL transport types onto plain Ruby objects. dsc uses that wrapper to dump computer inventory and Anti-Malware events as CSV.

Unmaintained. The last release is 0.0.25 (October 2013) and it targets the Deep Security Manager SOAP API as it existed then, on the Ruby 1.9.x / savon 2.x stack of that time. It has not been tested against later Deep Security versions.

Coverage is partial even for its own era: hosts, host groups, host details and Anti-Malware events work end to end. The Manager methods for security profiles, DPI rules, application types, system events and the HTML screen-scraping helpers (vulnerabilities, *_dpi_rule_identifiers) are leftovers from an earlier refactoring and call methods that no longer exist on Manager; they raise NoMethodError. Their transport object classes are still defined and are used for type mapping.

Add this line to your application's Gemfile:

gem 'deepsecurity'

And then execute:

$ bundle

Or install it yourself as:

$ gem install deepsecurity

Runtime dependencies, from the gemspec: savon, ruby-cache, gli, progressbar, json.

If you are using Windows and do feel familiar with the command line you may also download a bundled installer under http://deepsecurity-gem.s3.amazonaws.com/index.html

The bundled installer allows you to install a current Ruby version and the deepsecurity gem using a simple graphical installer.

The installer is built by rake windows_installer from windows-installer/dsc.iss (Inno Setup) and bundles Ruby 1.9.3-p448. The S3 index it is published to is generated by rake s3_index. Both date from 2013 and the download link may no longer be live.

DeepSecurity::Manager.server builds the SOAP client; Manager#connect authenticates and stores the session ID that is then passed implicitly to every subsequent call.

require 'deepsecurity'

# hostname, port (default 4119), log level (nil, :debug, :info, :warn, :error, :fatal), logger
manager = DeepSecurity::Manager.server('dsm.example.com', 4119)

manager.connect('', 'MasterAdmin', ENV['DSM_PASSWORD'])
begin
  # ... calls ...
ensure
  manager.disconnect
end

Details:

• The endpoint is hardcoded as https://<hostname>:<port>/webservice/Manager?WSDL. Only host and port are configurable; the scheme and path are not.
• TLS certificates are not verified. :ssl_verify_mode => :none is passed to both Savon and HTTPI and cannot be overridden through the public API.
• connect(tenant, username, password) calls the SOAP authenticate operation when tenant is empty and authenticateTenant otherwise. Failure raises DeepSecurity::AuthenticationFailedException.
• Calling an authenticated operation before connect raises DeepSecurity::AuthenticationRequiredException.
• disconnect calls endSession; it is a no-op when not authenticated.
• Retrieved objects are memoised in a process-wide cache (10000 entries, 5 minute TTL), so repeated hosts, host(id), host_group(id) and host_details calls within that window do not hit the manager again.
• Logging goes to STDERR. Passing a log level also enables Savon/HTTPI request logging, which includes the SOAP request bodies.

Unauthenticated calls:

manager.api_version    # => Integer, the web service API version
manager.manager_time   # => Time

Hosts and host groups:

manager.hosts                                   # => Array<DeepSecurity::Host>
manager.host(42)                                # => DeepSecurity::Host
manager.host_by_name('web01.example.com')       # => DeepSecurity::Host

manager.host_groups                             # => Array<DeepSecurity::HostGroup>
manager.host_group(3)                           # => DeepSecurity::HostGroup
manager.host_group_by_name('Production')        # => DeepSecurity::HostGroup

host = manager.host_by_name('web01.example.com')
host.id
host.name
host.display_name
host.platform
host.host_type          # => :standard, :esx, :appliance or :vm
host.host_group         # resolves host_group_id through the manager

Host details, the richer per-computer record (DeepSecurity::HostDetail < Host):

filter  = DeepSecurity::HostFilter.all_hosts
details = manager.host_details(filter, :low)    # detail level: :low, :medium or :high

details.each do |d|
  puts [d.name,
        d.platform,
        d.overall_status,
        d.anti_malware_engine_version,
        d.overall_last_successful_communication].join("\t")
end

Anti-Malware events:

events = manager.anti_malware_events_by_time_host_event(
  DeepSecurity::TimeFilter.last_24_hours,
  DeepSecurity::HostFilter.all_hosts,
  DeepSecurity::IDFilter.greater_than(0))

events.each do |e|
  puts [e.log_date, e.host.name, e.malware_name, e.malware_type, e.infected_file_path].join("\t")
end

DeepSecurity::HostFilter:

• all_hosts
• my_hosts
• specific_host(host_id)
• hosts_in_group(host_group_id)
• hosts_in_group_and_all_subgroups(host_group_id)
• hosts_using_security_profile(security_profile_id)

DeepSecurity::TimeFilter:

• last_hour
• last_24_hours
• last_7_days
• last_day — yesterday 00:00:00 to 23:59:59, expressed as a custom range
• custom_range(datetime_range)
• specific_time(datetime)

DeepSecurity::IDFilter:

• equals(id)
• less_than(id)
• greater_than(id)

All API types derive from DeepSecurity::TransportObject and declare their attributes through a small DSL (attr_string_accessor, attr_integer_accessor, attr_datetime_accessor, attr_enum_accessor, array_object_accessor, ...) that carries the Savon type conversion and a description string. The schema of any class is available programmatically:

DeepSecurity::HostDetail.all_type_mappings.each do |name, mapping|
  puts "#{name} (#{mapping.type_string}): #{mapping.description}"
end

Classes defined: Host, HostDetail, HostInterface, HostGroup, SecurityProfile, DPIRule, ApplicationType, ProtocolIcmp, ProtocolPortBased, SystemEvent, AntiMalwareEvent, AntiMalwareSpywareItem, plus the three filter types.

Reachable through Manager, and one level down through DeepSecurity::SOAPInterface:

dsc [global options] command [command options] [arguments...]

-m, --manager=hostname   Deep Security Manager host
    --port=port          Web service port (default: 4119)
-t, --tenant=tenant      Tenant name (default: empty, i.e. non-tenant authentication)
-u, --username=username  Username (default: MasterAdmin)
-p, --password=password  Password
-d, --debug=level        Client debug output: debug, info, warn, error or fatal (default: off)
-o, --outfile=file       Output filename (default: --, i.e. stdout)
-P, --progress_bar       Show a progress bar
    --help
    --version

-o/--outfile is broken: any value other than the default -- raises a NameError. Redirect stdout instead.

dsc api_version                 Display the web service API version (no authentication needed)
dsc manager_time                Display the manager's local time (no authentication needed)

dsc host_detail schema          List available host_detail fields with types and descriptions
dsc host_detail list            List host details as CSV

dsc anti_malware_event schema   List available anti_malware_event fields
dsc anti_malware_event list     List Anti-Malware events as CSV

list writes CSV with a header row of the selected field names. A field that raises during evaluation is emitted as ERROR (message) rather than aborting the run.

--fields=list          Comma separated field list, or a filename to read fields from
--detail_level=level   low, medium or high (default: low)
--time_format=format   strftime() format for date/time output

--fields=list          Comma separated field list, or a filename to read fields from
--time_filter=filter   last_hour, last_24_hours, last_7_days or last_day (default: last_day)
--time_format=format   strftime() format for date/time output

dsc -m dsm.example.com api_version

dsc -m dsm.example.com -u MasterAdmin -p secret host_detail list > hosts.csv

dsc -m dsm.example.com -u MasterAdmin -p secret \
    host_detail list --detail_level=high \
    --fields=name,platform,overall_status,anti_malware_engine_version

dsc -m dsm.example.com -t TenantA -u admin -p secret \
    anti_malware_event list --time_filter=last_7_days \
    --time_format='%Y-%m-%d %H:%M:%S'

dsc -m dsm.example.com host_detail schema

--fields takes a comma or whitespace separated list of accessor names. If the value names an existing file, the field list is read from that file instead, with # starting a comment. Fields may be chains of calls separated by dots, so host.name follows the host association of an event and name.size calls String#size on the result. Unknown fields abort the command and print the list of valid ones.

Default host_detail list fields: name, display_name, anti_malware_classic_pattern_version, anti_malware_engine_version, anti_malware_intelli_trap_exception_version, anti_malware_intelli_trap_version, anti_malware_smart_scan_pattern_version, anti_malware_spyware_pattern_version, overall_last_successful_communication, platform, host_type, host_group_name.

Default anti_malware_event list fields: host.name, host.display_name, log_date, start_time, end_time, scan_action1, scan_action2, summary_scan_result, scan_result_action1, scan_result_action2, malware_name, malware_type, infected_file_path, infection_source.

dsc.md holds additional notes on the command line client.

rake test               # Test::Unit tests in test/
rake                    # same, the default task
rake windows_installer  # build the Inno Setup installer (requires the Windows toolchain)

Test coverage is minimal: two files covering dsc time filter / time format parsing and a few savon_helper string helpers.
