Swift IDMEFv2 library

GitHub top language GitHub GitHub tag (latest by date) GitHub release (latest by date) GitHub issues Swift Package Manager

A Swift library for parsing, handling, and generating JSON IDMEFv2 messages. It can be used to represent Incident Detection Message Exchange Format (IDMEFv2) messages in memory, validate them and serialize/unserialize them for exchange with other systems.

IDMEFv2 messages can be transported using the swift-idmef-transport-library.

This code is currently in an experimental status and is regularly kept in sync with the development status of the IDMEFv2 format, as part of the SECurity Exchange Format project.

The latest revision of the IDMEFv2 format specification can be found there: https://github.com/IDMEFv2/IDMEFv2-Specification

You can find more information about the previous version (v1) of the Intrusion Detection Message Exchange Format in RFC 4765.

Compiling the library

The following prerequisites must be installed on your system to install and use this library:

  • Swift: version 5.5 or above

The library has the following third-party dependencies:

Note: building using swift automaticaly pulls the needed dependencies.

To compile the library:

swift build

This will build a bundle located in ./.build/.

Using the libray

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.

Once you have your Swift package set up, adding swift-idmef-library as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/teclib-idmef/swift-idmef-library.git", .upToNextMajor(from: "1.0.1"))

Message creation

A new message can be created by instantiating the IDMEFObject class. Once created, message fields can be set using array subscript operator.

import Foundation
import IDMEF

public class IDMEFExample {

    public static func message1() -> IDMEFObject {
        var msg = IDMEFObject()
        msg["Version"] = "2.0.3"
        msg["ID"] = UUID().uuidString
        msg["CreateTime"] = "2021-11-22T14:42:51.881033Z"

        var analyzer = [AnyHashable:Any](https://raw.github.com/teclib-idmef/swift-idmef-library/main/)
        analyzer["IP"] = ""
        analyzer["Name"] = "foobar"
        analyzer["Model"] = "generic"
        analyzer["Category"] = ["LOG"]
        analyzer["Data"] = ["Log"]
        analyzer["Method"] = ["Monitor"]

        msg["Analyzer"] = analyzer

        return msg

    static func main() {
        let msg = IDMEFExample.message1()
        let id = msg["ID"]
        print("message ID is \(id\)")

Message validation

You can validate an IDMEFv2 message using validate() method of IDMEFObjet. An exception is raised if the message is invalid.

/* see code above to generate IDMEF message */

if try !msg.validate() {
    print("message validation error")

print("message is valid")

Message serialization

Before the message can be sent to a remote system, it must be serialized using the serialize() method.

/* see code above to generate IDMEF message */

let jsonString = msg.serialize()

print("JSON: \(jsonString\)")

Message deserialization

Likewise, when a message is received in its serialized form, it must be first deserialized using the deserialize() class method.

import Foundation
import IDMEF

public class IDMEFExample {

    static func string1() -> String {
        return  "{\n" +
                "\"Version\":\"2.0.3\",\n" +
                "\"CreateTime\":\"2021-11-22T14:42:51.881033Z\",\n" +
                "\"ID\":\"09db946e-673e-49af-b4b2-a8cd9da58de6\",\n" +
                "\"Analyzer\":{\n" +
                "\"Category\":[\"LOG\"],\n" +
                "\"IP\":\"\",\n" +
                "\"Model\":\"generic\",\n" +
                "\"Data\":[\"Log\"],\n" +
                "\"Method\":[\"Monitor\"],\n" +
                "\"Name\":\"foobar\"\n" +
                "}\n" +

    static func main() {
        if let msg = IDMEFObject.deserialize(json: IDMEFExample.string1()) {
            let id = msg["ID"]
            print("message ID is \(id\)")
