• Identify and address risks and threats
• Security of infrastructure from a centralized location
• On-premises or in cloud
• Monitor security of workloads
• Collects security-related data from VM and other resources
• Monitor health of resources and implement
recommendations
• Ease configuration of your security

10
Analyses different components of environment

uncovered

11
Advanced Cloud Defense
• Adaptive application controls
• Just in time(JIT) VM access

• Gathers information related to performance, errors
& exceptions in applications
• Diagnose cause of problems that affect application
• Monitor release pipelines for application
• Improve your development lifecycle

Azure Application Insights
14
How It works
• Set up an Application Insights resource in Azure
portal
• Install an instrumentation package in application
• Package will monitor application and send log data
to Log Analytics workspace

Azure Sentinel
15
• Security information event management (SIEM)
• Security orchestration automated response
(SOAR) solution
• Collect data across users, devices, applications,
• On-premises , multiple clouds
• Detect & Investigate threats with artificial
intelligence
• Respond to incidents rapidly

Azure Monitor
16
• Service for collecting, combining, and analyzing data from different
sources
• Detect and diagnose issues across applications and dependencies with
Application Insights
• Correlate infrastructure issues with Azure Monitor for VMs and Azure
Monitor for Containers
• Drill into monitoring data with Log Analytics for Deep diagnostics
• Support alerts and automated actions
• Create visualizations with Azure dashboards and workbooks

Azure Monitor
17
Collects data from a range of components
• Application data
• Operating system data
• Azure resource data
• Azure subscription data
• Azure tenant data

Monitor Health Of VM
19
Default Basic Metrics for Azure VMs
• CPU usage
• Network traffic
• OS disk usage
• Boot success

Monitor Health Of VM
20
• To get a Full set of metrics install two tools on VM
• Azure Diagnostics extension
• Log Analytics agent
• Both tools are available for Windows and Linux
• Tools need storage account to save data that they collect

Question 1
In Azure Security Center Which tool allows to automate
responses to alerts?
a) Playbooks
b) Adaptive controls
c) FIM
d) Advanced cloud defense

22

Azure Alerts

Azure Alerts
24
• Proactively notify when conditions found in
monitoring data
• Identify and address issues before users of system
notice them

Key Attributes Of Alert Rule
25
• Target Resource
• VM, Storage account, Scale Set
• Signal
• Metric, Activity Log, Application Insights
• Criteria (Percentage CPU > 70%)
• Alert Name
• Alert Description
• Severity
• 0 Critical, 1 Error, 2 Warning, 3 Informational, 4 Verbose
• Action

Action Group
26
• Collection of notification preferences defined
• Azure Monitor and Service Health alerts use action
groups to notify users that an alert has been
triggered
• Various alerts may use the same action group or
different action groups depending on the user's
requirements.
• Configure up to 2,000 action groups in a
subscription

Available Actions
27
• Send an email or SMS message
• Create an Azure app push notification
• Make a voice call to a number
• Call an Azure function or Trigger a logic app
• Send a notification to a webhook
• Create an ITSM ticket
• Use a runbook (to restart a VM, or scale a VM up or down)

Question 2
Action group in Azure Alert is a collection of notification
preferences.
a) True
b) False
28

Question 2
Action group in Azure Alert is a collection of notification
preferences.
a) True
b) False

Log Analytics

Log Analytics
31
• Collects telemetry from Windows and Linux VM
• From any cloud, on-premises machines, and those monitored
by SCOM
• Sends collected data to Log Analytics workspace in Azure
Monitor
• Supports insights and other services in Azure Monitor
• Azure Monitor for VMs,
• Azure Security Center
• Azure Automation
• No cost for Log Analytics agent, charges for data ingested

Log Analytics Data collected
32
• Windows Event logs
• Syslog Linux event logging system
• Performance Numerical values measuring
performance of different aspects of OS and
workloads
• IIS logs
• Custom logs Events from text files on both
Windows and Linux computers

Log Analytics Agent Installation
33
• Azure VM
• Azure Monitor can enable agents at scale
• Azure Security Center can provision the Log Analytics Agent
• VM extension for Windows or Linux
• Azure portal
• Windows VM on-premises or in another cloud
• Manually from command line
• Azure Automation DSC
• Resource Manager template with Azure Stack
• Linux virtual machine on-premises or in another cloud
• Manually wrapper-script hosted on GitHub
• SCOM

Network Watcher
34

Network Watcher
35
• Central place to diagnose health of Azure Networks
• Two categories:
• Monitoring Tools
• Diagnostic Tools

Network Watcher Monitoring Tools
36
Monitoring Tools:
• Topology
• Connection Monitor
• Network Performance Monitor

Network Watcher Topology
37
Reference : Microsoft Docs

Network Watcher Diagnostic Tools
38
• IP Flow Verify
• Next Hop
• Effective Security Rules
• Packet Capture
• Connection Troubleshoot
• VPN Troubleshoot

IP Flow Verify
39
• Checks if a packet is allowed or denied to or from
a VM
• Based on 5-tuple information
• Specify
• Local and Remote port,
• Protocol (TCP or UDP),
• Local IP, Remote IP,
• VM, and VM’s NIC
• NSG name of rule that denied packet is returned

Next Hop
40
• Provides next hop from target VM to destination IP
address
• How a packet gets from a VM to any destination
• Specify source VM /network adapter/IP address, and
destination IP address
• Tool determines packet's destination
• Diagnose problems caused by incorrect routing
tables

Effective Security Rules
41
• Displays all effective NSG rules applied to a network
interface
• Choose a VM and its network adapter
• Tool displays all NSG rules that apply to that adapter
• Also spot vulnerabilities for VM caused by unnecessary
open ports

Packet Capture
42
• Record all of packets sent to and from a VM
• VM extension through Network Watcher and automatically
with packet capture session
• Limit is 100 packet capture sessions per region
• Overall limit is 10,000
• Limits are for the number of sessions only, not saved
captures
• Save packets captured in Azure Storage or locally on
computer

Connection Troubleshoot
43
• Check TCP connection from a VM to a VM, FQDN, URI, or IPv4 address
• Connection successful information:
• Latency in milliseconds
• Number of probe packets sent
• Number of hops in the complete route to destination
• Connection unsuccessful shows Fault Details:
• Failed because of high CPU utilization
• Failed because of high memory utilization
• GuestFirewall blocked by a firewall outside Azure
• DNSResolution destination IP address couldn't be resolved
• NetworkSecurityRule blocked by an NSG
• UserDefinedRoute incorrect user route in a routing table

VPN Troubleshoot
44
• Diagnoses health of virtual network gateway or
connection
• Multiple gateways or connections can be
troubleshooted simultaneously

Question 3

Network Watcher tool we can use?
a) Connection Troubleshoot
b) IP Flow Verify
c) Next Hop
d) Security Group View
