Windows Defender ATP agent is now in-box – no download required.Emits health assertions (claims) that can be consumed by downstream relying parties System Guard Runtime Monitor – Someone to keep an eye on everything else. Monitors the binaries to ensure it runs as it was designed to do. Kernel Control Flow Guard (CFG) – CFG ensures user and kernel-mode binaries stay on the rails/run as expected.Device Guard policy updates can now be applied without a reboot – New default policies ship in-box.Shielded VM improvements – branch office support, simpler cloud-friendly attestation (3 commands to get a host to participate in Guarded Fabric – doesn’t supply as strong assurance as TPM but allows dipping toe into guarded fabric), Linux OSes, and troubleshooting capabilities by using enhanced virtual machine configuration consoles.There are several new security features that are found in Windows Server 2019, many of which are extensions of current capabilities that were introduced in Windows Server 2016 and Windows 10. Windows Server 2019 New Security Features Security is an architectural principle not a bolt on. Isolate – Isolate OS components & secrets limit admin privileges rigorously measure host health.Respond – Leading response and recovery technologies plus deep consulting expertise.Detect – Comprehensive monitoring tools to help you spot abnormalities and respond to attacks faster.Protect – ongoing focus & innovation on preventative measures block known attacks & known malware.Much of the information presented below was summarized from the Windows Server Summit event held this summer.įour principles of security – protect, detect, respond, isolate. Common attack vectors that Windows Server 2019 Security Features help to prevent (image courtesy of Microsoft Windows Server Summit) Common principles found in Windows Server 2019 Security Architecture Attacking the fabric of the virtualization technology can get an attacker highly privileged access to data. Privileged accounts have the keys to the kingdom and can easily be compromised via social engineering, bribery, coercion, private initiatives, etc.Īnother layer of many security vulnerabilities were introduced with virtualization. In fact, the goal of most attacks is to seek out privileged accounts. When looking at various security attacks, whether it be – phishing attacks, stolen creds, pass-the-hash, insider attacks, fabric attacks, all have in common administrative privileges. Often times, control is established of a particular device and then use credentials gained to gain control over additional devices. With this level of access, they can grant themselves access to the resources and data in the environment they truly want. Generally, they can continue to move laterally across an environment stealing different types of credentials until they stumble upon a cached domain administrator credential. Using domain credentials access can be granted by the attacker and give themselves access to the data they actually want. Normally pass the hash attack is used to get unauthorized credentials from the system’s memory. A very common way that attackers gain control of an environment is by stealing credentials. When looking at attacks from the standpoint of an attacker, there is a research and preparation time which is typically 24-48 hours statistically before any malicious activity is carried out. How Compromises in Security Happenīefore taking a look at the new Windows Server 2019 security features, let’s take a step back and see how compromise happens. With Windows Server 2019 soon to be released, let’s take a look at Windows Server 2019 New Security Features and how these will better equip businesses today to have better security and visibility to security events. With each version of Windows Server, Microsoft has greatly improved the security stance by including new features, functionality, and tools that allows organizations to be more secure and have the ability to gain better visibility into their environments powered by Windows Server. With high profile breaches and data leaks reported in major news headlines, security is on the radar of both IT professionals and C-level executives alike. There is no doubt about it that security is on the minds of everyone today.
