The topics include an overview of Microsoft Sentinel and Microsoft Defender, designing and implementing Microsoft Sentinel, using Kusto to query data logs, creating analytics rules in Sentinel, and monitoring vulnerabilities with Microsoft Defender.Chapter 4: Ransomware Countermeasures – Windows Endpoints, Identity, and SaaS.Ransomware attacks often exploit vulnerabilities in network infrastructure to propagate and spread across an organization's systems. In this chapter, the content goes deeper into various countermeasures that can help reduce the risk of ransomware attacks on critical attack vectors, including endpoints, identity, email services, and network attacks. Topics reviewed include: securing Windows endpoints with Microsoft Intune and Azure AD endpoints, implementing attack surface reduction rules and browser protection mechanisms such as SmartScreen and Application Guard, safeguarding user identities in Azure AD and SaaS services, improving email security in Office 365 to reduce the risk of phishing attacks and additional tips and tricks for securing Windows endpoint.Chapter 5: Ransomware Countermeasures – Microsoft Azure WorkloadsDespite the best preventive measures, organizations may still fall victim to ransomware attacks. As more organizations migrate their virtual machine workloads to the cloud, it is crucial to understand the various security mechanisms and the appropriate architecture before deploying infrastructure. In most cases, individuals and organizations that have fallen victim to ransomware or had information exposed after moving their workloads to the public cloud were due to a lack of knowledge or inadequate security measures.This chapter explores the theory behind constructing a secure architecture in Microsoft Azure for virtual machine workloads. It covers the following additional topics: network segmentation and design best practices in Microsoft Azure, protecting external services with DDoS and WAF mechanisms, security best practices for Identity and Access Management in Azure, safeguarding hybrid workloads with Azure Arc, identity and access management in Microsoft Azure, and data protection using Azure Backup and Azure Policy.Chapter 6: Ransomware Countermeasures – Networking and Zero-Trust Access.Most ransomware attacks originate from a compromised device or an externally available vulnerable service, such as a VPN or VDI, which attackers exploit. These attacks typically provide the attacker with an initial foothold, allowing them to gain further access to the infrastructure. Many of these attacks can be prevented if the end-user device does not have access to the infrastructure or the service is not externally available.This chapter reviews alternatives for securely accessing services externally using a zero-trust-based access model without exposing ourselves to the same risks. It also examines best practices for network segmentation and security for Windows-based workloads and methods for protecting our external web services from Distributed Denial-of-Service (DDoS) attacks, an increasingly common attack vector. Additionally, the chapter reviews SASE service models and how they can help reduce the risk to the mobile workforce.The topics covered include zero-trust network access and SASE services, network segmentation, firewalls, access control, and DDoS protection and security for new web services."Chapter 7: Protecting Information Using Azure Information Protection and Data ProtectionIn recent years, ransomware attacks have evolved from simply encrypting data to exfiltrating it because many companies realized they could restore encrypted files from backups, negating the need to pay the ransom. To increase the likelihood of receiving payment, ransomware groups have begun exfiltrating any data they can find.In this book chapter, the author explores how to use services to encrypt data and lower the probability that it falls into the wrong hands. Built-in Windows and Azure Information Protection (AIP) services are reviewed and shared best data protection and backup practices are discussed. The topics include the importance of classifying and encrypting your data, an overview of AIP, DLP features and the future of AIP, encrypting SQL-based workloads, and best practices for data protection and backups.Chapter 8: Ransomware ForensicsNo matter how many countermeasures are implemented or how advanced the security measures are, it is impossible to be wholly protected from cyberattacks. As such, it is crucial to know how to respond in the event of an attack and to conduct a post-incident review to determine how the attack occurred. Many corporations that have fallen victim to ransomware and paid the ransom have been attacked again just weeks later because they failed to address the vulnerability or implement appropriate countermeasures.This chapter covers conducting ransomware forensics and responding to an attack, examining the filesystem, registry, and events from your infrastructure, identifying the type of ransomware and common attack vectors, and removing the entry point used by the attackers after restoring your systems.Chapter 9: Monitoring the Threat LandscapeThe threat landscape is constantly changing, making it essential for IT professionals to have access to tools and news sources that enable them to stay informed about current threats.
