With Windows Server 2019, Microsoft is adding resiliency and redundancy enhancements to the Shielded Virtual Machines security controls it introduced with Windows Server 2016.Shielded VMs originally provided a way to protect virtual machine assets by isolating them from the hypervisor infrastructure and could also help prove to auditors that systems were adequately isolated and controlled. Now Shielded VM enhancements in Window Server 2019 provide real-time failback configurations and host- and policy-based security improvements.[ Don’t miss customer reviews of top remote access tools and see the most powerful IoT companies . | Get daily insights by signing up for Network World newsletters. ]
Host key attestation
Under Windows Server 2016, key authentication was based on trusted platform module (TPM) cryptoprocessors and Microsoft Active Directory authentication.  Both of these are great solutions but were limited when it comes to extensibility and redundancy.To read this article in full, please click here(Insider Story) READ MORE HERE…

TH Author , , ,

There are many aspects to security on Linux systems – from setting up accounts to ensuring that legitimate users have no more privilege than they need to do their jobs. This is look at some of the most essential security commands for day-to-day work on Linux systems.sudo
Running privileged commands with sudo  – instead of switching user to root  – is one essential good practice as it helps to ensure that you only use root privilege when needed and limits the impact of mistakes. Your access to the sudo command depends on settings in the /etc/sudoers and /etc/group files. [ Two-Minute Linux Tips: Learn how to master a host of Linux commands in these 2-minute video tutorials ]

Adding user `shark’ …
Adding new group `shark’ (1007) …
Adding new user `shark’ (1007) with group `shark’ …
