Introducing Azure Advanced Threat Protection

The recent years have witnessed a distinct and consistent escalation in cyberattacks’ scope, scale, and sophistication, impacting organizations across all verticals and locations. This escalation is manifested not only in increasing proliferation of threat-actor groups, but also in the diversity of the utilized attack Tools Techniques and Procedures (TTPs), ranging from zero-day exploits to weaponized antimalware and publicly available toolkits.

This threat landscape is driving a change in the common security paradigm, bringing security stakeholders to realize that a resourceful and determined attacker will at a certain point succeed in bypassing the traditional prevention and detection controls.

To proactively respond to these threats, there is a need for a security layer that operates following the successful bypass of these controls and is tasked with detecting the malicious activity consecutive to this bypass.

Step by Step Virtual Machine Creation in Azure

Azure Virtual Machines (VM) is one of several types of on-demand, scalable computing resources that Azure offers. Typically, you choose a VM when you need more control over the computing environment than the other choices offer. This article gives you information about what you should consider before you create a VM, how you create it, and how you manage it.

An Azure VM gives you the flexibility of virtualization

Step by Step Establishing Azure Point to Site VPN

There are many scenario in which we have to work on Microsoft Azure Cloud doing experiments
and LABs, or we have to setup some Application Server’s on which different people have to work
like a team, such as a team of developer is working on a project which is hosted on Microsoft Azure plate from and the developers are located in different geo location.

Step by Step Azure Site to Site VPN with SonicWall Hardware Firewall

Azure is a cloud computing platform and infrastructure created by Microsoft. It is used for building, deploying, and managing applications and services through a global network of Microsoft managed datacenters.

Windows Hello for Business


In Windows 10, Windows Hello for Business replaces passwords with strong two-factor authentication on PCs and mobile devices. This authentication consists of a new type of user credential that is tied to a device and uses a biometric or PIN.
Windows Hello for Business lets user authenticate to an Active Directory or Azure Active Directory account.

if you have only office 365 subscription and windows 10 then also your user able to login through windows hello no need local AD.
Windows Hello addresses the following problems with passwords:
  • Strong passwords can be difficult to remember, and users often reuse passwords on multiple sites.
  • Server breaches can expose symmetric network credentials (passwords).
  • Passwords are subject to replay attacks.
  • Users can inadvertently expose their passwords due to phishing attacks.

Petya ransomware prevention & detection in Azure Security Center

This blog post was authored by Tim Burrell, Principal Engineering Manager, Microsoft Threat Intelligence Center .
Microsoft Malware Protection Center (MMPC) published a blog post yesterday detailing a new ransomware infection that appears to have begun in Ukraine and spread from there to other places in Europe and beyond. MMPC analysis showed this to be a more sophisticated variant of Ransom:Win32/Petya and all free Microsoft antimalware products were updated with signatures for this threat, including Windows Defender Antivirus.
This post summarizes measures that Azure customers can take to prevent and detect this threat through Azure Security Center. See here for basic information on enabling Azure Security Center.

Prevention

Azure Security Center scans virtual machines across an Azure subscription and makes a recommendation to deploy endpoint protection where an existing solution is not detected. This recommendation can be accessed via the Prevention section as shown below.
Security Center - Overview
Drilling into the Compute pane (or the overview recommendations pane) shows more detail, including the Endpoint Protection installation recommendation being discussed here:
Compute
Clicking on this leads to a dialog allowing selection of and installation of an endpoint protection solutions, including Microsoft’s own antimalware solution:
Install Endpoint Protection
Select Endpoint Protection
These recommendations and associated mitigation steps are available to Azure Security Center Free tier customers.

Detection

Azure Security Center customers who have opted into Standard-Tier can benefit from a new detection recently added to alert on specific indicators related to Petya ransomware running on an infected host - this is described in further detail below.
These alerts are accessed via the Detection pane highlighted below, and require the Azure Security Center Standard tier.
Security Center
An alert for Petya ransomware will show up as shown below:
Detected Petya
Drilling in provides more detail of the impacted VM and suspicious process or commandline that triggered the alert:
Detected Petya ransomware indicators
Note that although the detection alert relates to a specific host, because this ransomware attempts to propagate to other nearby machines, it is important to apply remediation steps to all on all hosts on the network, not just the host identified in the alert.
Please follow the remediation steps indicated in the Alert or in the Microsoft Malware Protection Center (MMPC) blog.

Step by Step Windows Azure Point to Site VPN



There are many scenario in which we have to work on Microsoft Azure Cloud doing experiments and LABs, or we have to setup some Application Server’s on which different people have to work like a team, such as a team of developer is working on a project which is hosted on Microsoft Azure plate from and the developers are located in different geo location. These kind of scenario for which Azure provides Point to Site VPN Secure connectivity so that every individual connect remotely with a secure SSTP VPN connection and perform his job.
A Point-to-Site (P2S) configuration lets you create a secure connection from an individual client computer to a virtual network. P2S is a VPN connection over SSTP (Secure Socket Tunneling Protocol). Point-to-Site connections are useful when you want to connect to your VNet from a remote location, such as from home or a conference, or when you only have a few clients that need to connect to a virtual network. P2S connections do not require a VPN device or a public-facing IP address. You establish the VPN connection from the client computer. In this Lab, we will walk through the steps involved in setting up a remote P2S VPN with Microsoft Windows Azure Cloud plate form.

LAB Setup for Azure VPN

 










We need to following requirements before we start P2S VPN.
 
·       A valid Microsoft Azure subscription
·       Microsoft Windows SDK at client computers installed
·       Root and Client Certificate at client computers
·       Virtual Network in Azure
·       Network Subnet
·       Virtual Network Gateway in Azure
·       Gateway Subnet

Windows Azure Virtual Network


After successful login click New and search Virtual Network

 

Select Virtual Network, Select Resource Group and Click Create

 


Virtual Network Properties

Fill out Virtual Network properties as per your Network

 


Location you can chose as per your nearest Azure Data Center and click create it will take approximate 2 to 3 minutes and V Network will be created.

View Properties of Virtual Network  


You can view newly created virtual network settings, resource group and address space.
