STM32 - Das umfassende Praxisbuch (2. Auflg.)
ARM-Microcontroller programmieren für Embedded Systems - Das umfassende PraxisbuchMit diesem Buch erhalten Sie einen umfassenden Praxiseinstieg für die Softwareentwicklung für Embedded Systems mit der ARM-Mikrocontrollerfamilie STM32F4xx der Firma STMicroelectronics (STM). Für die Programmierung wird die Sprache C eingesetzt.Der Autor behandelt die wichtigsten Peripherie-Komponenten, dazu gehören digitale und analoge I/O-Ports (GPIOs), Timer und Counter, serielle Schnittstellen (USARTs/UARTs, SPI und I2C), ADCs und DACs, RTC (Echtzeit-Uhr) sowie Direct Memory Access (DMA).Die Programmierung dieser Komponenten zeigt der Autor anhand einfacher praktischer Anwendungsbeispiele wie z.B. die Abfrage von Uhrzeit und Datum von einer externen RTC (über I2C) sowie deren Anzeige über SPI auf einfachen Displays. Dabei entsteht im Verlauf des Buchs eine Bibliothek, deren Funktionen für eigene Projekte auf einfache Weise eingesetzt werden können.Als Entwicklungsumgebung wird STM32CubeIDE von STM verwendet. Außerdem kommt das Evaluierungsboard NUCLEO-64 für den STM32F446 zum Einsatz. Der Autor legt Wert darauf, alles »bare-metal« zu programmieren und verzichtet darauf, die HAL-Bibliothek einzusetzen. Diese Vorgehensweise erleichtert Ihnen auch den Umstieg auf Mikrocontroller anderer Hersteller. Grundlegende Kenntnisse der Programmiersprache C werden vorausgesetzt. Dennoch wird auf einige Aspekte eingegangen, die in der Bare-metal-Programmierung von Mikrocontrollern möglicherweise wichtiger sind als in der Entwicklung herkömmlicher PC-basierter Software.Aus dem Inhalt: Typische GPIO-Anwendungen (Input/Output/Alternative Funktionen)Timer: Systick/Basic/General Purpose/Advanced Control TimerPWM: Dimmen von LEDs mit TimernA/D- und D/A-WandlungSerielle Kommunikation mit UARTs/USARTs/I2C/SPIPorterweiterung mit I2C (PCF8574)/Ansteuerung von LC-Displays7-Segment-Anzeigen über SPI (MAX7219)Einsatz einer externen Echtzeituhr (RTC) DS3231 über I2CAutor: Ralf Jesse ist Diplom-Ingenieur der Elektrotechnik mit mehr als 30 Jahren beruflicher Praxis im Einsatz von Mikroprozessoren und -controllern.

Informationssicherheit
Dieses Buch erklärt die wichtigsten Fachbegriffe und Inhalte und ordnet diese den entsprechenden Bereichen zu. Einbezogen werden auch scheinbare Randgebiete, die für die Informationssicherheit ebenfalls eine Rolle spielen. So wird der Themenkomplex Safety und Privacy hinsichtlich seiner Gemeinsamkeiten und Unterschiede beleuchtet. Das Buch zeigt aktuell verwendete Angriffsmuster und wie man sich dagegen schützen kann. Schutz muss dabei sowohl auf technischer Ebene (z. B. durch den Einsatz von Kryptographie) als auch auf organisatorischer und personeller Ebene (z. B. durch entsprechende Managementsysteme und Awareness-Schulungen) erfolgen. Wie lässt sich feststellen, wie sicher Daten sind? Wie lassen sich relevante Bedrohungen finden, gegen die man sich schützen muss? Wie verlaufen Risikoanalysen?

The Definitive Guide to Security in Jakarta EE
Refer to this definitive and authoritative book to understand the Jakarta EE Security Spec, with Jakarta Authentication & Authorization as its underlying official foundation. Jakarta EE Security implementations are discussed, such as Soteria and Open Liberty, along with the build-in modules and Jakarta EE Security third-party modules, such as Payara Yubikey & OIDC, and OmniFaces JWT-Auth.The book discusses Jakarta EE Security in relation to SE underpinnings and provides a detailed explanation of how client-cert authentication over HTTPS takes place, how certifications work, and how LDAP-like names are mapped to caller/user names. General (web) security best practices are presented, such as not storing passwords in plaintext, using HTTPS, sanitizing inputs to DB queries, encoding output, and explanations of various (web) attacks and common vulnerabilities are included.Practical examples of securing applications discuss common needs such as letting users explicitly log in, sign up, verify email safely, explicitly log in to access protected pages, and go direct to the log in page. Common issues are covered such as abandoning an authentication dialog halfway and later accessing protected pages again.WHAT YOU WILL LEARN* Know what Jakarta/Java EE security includes and how to get started learning and using this technology for today's and tomorrow's enterprise Java applications* Secure applications: traditional server-side web apps built with JSF (Faces) as well as applications based on client-side frameworks (such as Angular) and JAX-RS* Work with the daunting number of security APIs in Jakarta EE* Understand how EE security evolvedWHO THIS BOOK IS FORJava developers using Jakarta EE and writing applications that need to be secured (every application).

Superbundle: iX kompakt Sicheres Active Directory (Heft + PDF + Buch)
Das neue Sonderheft der iX-Redaktion zum kritischen Thema "Sicheres Active Directory" versammelt alle in iX erschienenen themenbezogenen Artikel der letzten Monate in aktualisierter überarbeiteter Form in einem Heft.Komplett im Set: gedrucktes Heft + digitale Ausgabe + Fachbuch zur Microsoft-Zertifizierung mit 17,99 Euro Ersparnis!"Das Heft behandelt die Sicherheit von Active Directory, der zentralen Komponente von typischen On-Premises-Netzwerken, sowie von Azure Active Directory, dem Identitätsdienst bei Microsofts Cloud. Beschrieben werden Grundlagen, das Vorgehen von Eindringlingen – und wie man Angriffe verhindert, erkennt und untersucht. Es eignet sich damit sehr gut für Administratoren und Sicherheitsverantwortliche, die Microsoft-Produkte lokal oder in der Cloud nutzen. Mit diesem Wissen können sie Ransomware und andere Angriffe abwehren."- Frank Ully, Head of Research bei der Oneconsult AG, München, leitet zahlreiche iX-Workshops zur Active-Directory-Sicherheit und ist Autor vieler wichtiger Artikel dieses SonderheftsDer komplette Inhalt im Überblick:Grundlagen Microsofts Active Directory ist der am meisten genutzte Verzeichnisdienst weltweit – kein Wunder, lassen sich damit die Ressourcen eines Unternehmens äußerst komfortabel verwalten. Das macht das AD aber auch zu einem beliebten Angriffsziel. Wer verstehen will, wie Cyberkriminelle den zentralen Dienst angreifen und wie man ihn absichert, muss wissen, wie das AD grundlegend funktioniert. (Seite 7) Angriffsszenarien Durch Fehler bei der Konfiguration, mangelnde Härtung oder zu großzügige Rechtevergabe im Active Directory entstehen Einfallstore für Angriffe. Cyberkriminellen kann es dann gelingen, das gesamte AD zu übernehmen, um ihre kriminellen Ziele zu verfolgen. Nur wer weiß, wie die Kriminellen vorgehen und wie die verbreiteten Angriffe funktionieren, kann sich davor schützen. (Seite 41) Abwehrstrategien Es gibt viele Ansätze, das AD vor Angreifern zu schützen. Die Bandbreite reicht von präventiven Maßnahmen mit Windows-Bordmitteln und Drittanbietertools über Sicherheitsaudits bis hin zu grundlegenden Sicherheitsvorkehrungen, etwa nach IT-Grundschutz. Gelingt den Kriminellen trotzdem der Zugriff, muss der Angriff so schnell wie möglich entdeckt, forensisch aufbereitet und analysiert werden. (Seite 79) Azure AD Wenn Unternehmen Microsoft 365 oder andere Dienste aus der Azure-Cloud einsetzen, nutzen sie den Cloud-Identitätsdienst Azure AD – vielleicht ohne sich dessen überhaupt bewusst zu sein. Wie beim On-Premises Active Directory können auch hier mangelnde Härtung und Fehlkonfigurationen dazu führen, dass Angreifer einzelne Identitäten, Ressourcen oder gar das komplette Azure AD kompromittieren – und schlimmstenfalls darüber Zugriff auf das lokale AD erlangen.
