This document discusses the differences between monitoring virtual infrastructures and performing in-depth analysis. Monitoring tools provide real-time insight into infrastructure health by alerting administrators if thresholds are exceeded. However, in-depth analysis goes further by systematically evaluating data according to rules and best practices to identify issues proactively and determine root causes. In-depth analysis tools can automate this process and provide recommendations to optimize systems. Such analysis reduces troubleshooting burden on administrators and helps ensure high performance, security and reliability compared to monitoring alone.
Is Using Off-the-shelf Antimalware Product to Secure Your Medical Device a Go...Jose Lopez
Most vendors, who create embedded devices – especially medical devices such as medical X-Ray connected machines, connected Labs and other equipment – are smart, and understand the need of securing them against external threats
such as malware. Such devices often run a common operating system such as Windows Embedded, or Linux and are susceptible to many kinds of malware threats as their non-embedded threats. Thus, protection against malware is important consideration when securing such devices.

Derek Milroy, IS Security Architect at U.S. Cellular Corporation, defined “vulnerability management” and how it affects today’s organizations during his presentation at the 2014 Chief Information Security Officer (CISO) Leadership Forum in Chicago on Nov. 19. In his presentation, “Enterprise Vulnerability Management/Security Incident Response,” Milroy noted vulnerability management has different meanings to different organizations, but an organization that utilizes vulnerability management processes can effectively safeguard its data.
According to Milroy, an organization should develop its own vulnerability management baselines to monitor its security levels. By doing so, Milroy said an organization can launch and control vulnerability management systems successfully. In addition, Milroy pointed out that vulnerability management problems occasionally will arise, but a well-prepared organization will be equipped to handle such issues: “Problems are going to happen … You have to work with your people. This can translate to any tool that you’re putting in place. Make sure your people have plans for what happens when it goes wrong, because it’s going to [happen] every single time.”
Milroy also noted that having actionable vulnerability management data is important for organizations of all sizes. If an organization evaluates its vulnerability management processes regularly, Milroy said, it can collect data and use this information to improve its security: “The simplest rule of thumb for vulnerability management, click the report, hand the report to someone. Don’t ever do that. There is no such thing as a report from a tool that you can just click and hand to someone until you first tune it and pare it down.”

An Introduction to Prometheus (GrafanaCon 2016)Brian Brazil
Often what you monitor and get alerted on is defined by your tools, rather than what makes the most sense to you and your organisation. Alerts on metrics such as CPU usage which are noisy and rarely spot real problems, while outages go undetected. Monitoring systems can also be challenging to maintain, and overall provide a poor return on investment.
In the past few years several new monitoring systems have appeared with more powerful semantics and which are easier to run, which offer a way to vastly improve how your organisation operates and prepare you for a Cloud Native environment. Prometheus is one such system. This talk will look at the monitoring ideal and how whitebox monitoring with a time series database, multi-dimensional labels and a powerful querying/alerting language can free you from midnight pages.
Fault Detection and Prediction in Cloud Computingijtsrd
Cloud computing is a new technology in distributed computing. Usage of Cloud computing is increasing quickly day by day. In order to help the customers and businesses agreeably, fault occurring in datacenters and servers must be detected and predicted efficiently in order to launch mechanisms to bear the failures occurred. Failure in one of the hosted datacenters may broadcast to other datacenters and make the situation of poorer quality. In order to prevent such circumstances, one can predict a failure flourishing throughout the cloud computing system and launch mechanisms to deal with it proactively. Swetha. S | Dr. S.

WHITE PAPER: Threats to Virtual Environments - Symantec Security Response TeamSymantec
Virtualization in enterprises has been a growing trend for years, offering attractive opportunities for scaling, efficiency, and flexibility. According to Forrester Research1, over 70 percent of organizations are planning to use server virtualization by the end of 2015.
Often, companies delay implementing virtualization due to security concerns or adopt virtualization before deploying advanced security measures. However, virtual machines and their hosting servers are not immune to attack. Introducing virtualization technology to a business creates new attack vectors that need to be addressed, such as monitoring the virtual networks between virtual machines. We have seen malware specifically designed to compromise virtual machines and have observed attackers directly targeting hosting servers. Around 18 percent of malware detects virtual machines and stops executing if it arrives on one.
Virtual systems are increasingly being used to automatically analyze and detect malware. Symantec has noticed that attackers are creating new methods to avoid this analysis. For example, some Trojans will wait for multiple left mouse clicks to occur before they decrypt themselves and start their payload. This can make it difficult or impossible for an automated system to come to an accurate conclusion about the malware in a short timeframe. Attackers are clearly not ignoring virtual environments in their plans, so these systems need to be protected as well.

Solution
Part1:-
There are three things that can enhance operating system security across an enterprise network:
First, provisioning of the servers on the network should be done once in one place, involving the
roughly tens of separate configurations most organizations require. This image, or set of images,
can then be downloaded across the network, with the help of software that automates this process
and eliminates the pain of doing it manually for each server. Moreover, even if you had an
instruction sheet for these key configurations, you wouldn\'t want local administrators to access
these key configurations for each server, which is very dangerous. The best way to do it is once
and for all.
Once the network has been provisioned, administrators need to be able to verify policy
compliance, which defines user access rights and ensures that all configurations are correct. An
agent running on the network or remotely can monitor each server continuously, and such
monitoring wouldn\'t interfere with normal operations.
Second, account management needs to be centralized to control access to the network and to
ensure that users have appropriate access to enterprise resources. Policies, rules and intelligence
should be located in one place—not on each box—and should be pushed out from there to
provision user systems with correct IDs and permissions. An ID life cycle manager can be used
to automate this process and reduce the pain of doing this manually.
Third, the operating system should be configured so that it can be used to monitor activity on the
network easily and efficiently—revealing who is and isn\'t making connections, as well as
pointing out potential security events coming out of the operating system. Administrators can use
a central dashboard that monitors these events in real time and alerts them to serious problems
based on preset correlations and filtering. Just as important, this monitoring system should be set
up so that administrators aren\'t overwhelmed by routine events that don\'t jeopardize network
security.

1. Introduction
1.1 Virtual infrastructures are becoming increasingly complex
Virtualization is an indispensable part of a modern data center. Frequently, the
degree of virtualization is 90 percent or more. What formerly operated on a number
of servers today runs on a few hosts. With the high rate of virtualization and the
resulting increase in complexity, problems are more difficult to locate. It is therefore
necessary to consider how the infrastructure can be monitored accurately and how
potential error situations can be found to avoid costly errors. Unfortunately, under
certain circumstances, even minor problems can significantly negatively impact the
entire infrastructure.
1.2 A Wide range of virtualization solutions and infrastructure
components
Virtualization solutions are many: the selection ranges from suppliers such as KVM
and Citrix to Microsoft Hyper-V and the market-leading provider VMware, with its
vSphere solution. The variety of combinations with other components of the
infrastructure is limitless. Reduced to its basic functionality, each of these solutions
operates almost the same way. They mainly enable resource partitioning for optimal
and cost-effective use of physical hardware. In addition, completely new methods of
high-availability designs are possible.
1.3 Keeping systems reliable through monitoring
What about the reliability of the virtualized machines (VMs)? Are the smooth
operation of VMs and the applications running on your systems guaranteed?
Keeping track of this complex infrastructure can be guaranteed only by employing
various tools, with at least one monitoring solution serving as the base. The aim is to
be promptly notified if system loads are exceeded or failures occur. In many
organizations, failure prevention tools offer 99.9% even 99.99% reliability. Such
statistics are not possible without appropriate software and automation.
4. A deep analysis of virtual infrastructures & monitoring 4
2. Operating Monitoring solutions
Monitoring tools are widespread, such as Nagios or Icinga, Microsoft SCOM or
proprietary and application-specific monitoring tools (e.g. integrated in VMware
vCenter). They offer real-time insight on whether certain thresholds are exceeded
or if a failure has occurred. If this is the case, then the software alerts the
administrator through email or SMS sounds an alarm.
2.1 Setting the right threshold
The biggest challenge is the correct setting of the threshold value, since this
threshold determines whether an action should be performed or not. For example,
sensitive thresholds lead to many alerts and alarms, and administrators are flooded
with harmless or false messages. This causes really important messages to
sometimes be overlooked in the crowd. But what is the correct threshold for an
administrator? This must be decided based on the unique infrastructure. But of
course, recommendations and best practices exist that can be implemented and
provide guidance.
3. Depth ANALYSIS?
3.1 Removing ambiguity
An analysis is by definition a systematic study which consists of two processes, data
collection and evaluation. In particular, we consider this relationship and its effects
and interactions between the elements. In the analysis it is always about the
evaluation of the data obtained.
3.2 The difference between in-depth analysis and monitoring
Fig. 1
5. A deep analysis of virtual infrastructures & monitoring 5
On Fig. 1. you can recognize how an issue could escalate if it is not detected by in-
depth analysis. The time to act could be increased tremendously if a tool for in-depth
Detection has been set up in the infrastructure.
An in-depth analysis of the infrastructure is usually tested in accordance with rules,
security and best practices. It's less about the actual state of the load, but rather the
HOW, i.e. how something is configured. For example, a message such as "100% CPU
utilization" appearing without more information would not be very helpful. Here
you can already see a clear distinction between pure monitoring and analysis. You
want to know why the reported problem occurred and how it can be fixed.
Therefore, an automatic recognition after troubleshooting and recording would be
ideal.
A typical example which comes into play at each virtualization manufacturer involves
the topics vCPU (virtual CPU) and vMemory (memory which is assigned to a virtual
machine). Surely every administrator has received a request to create a virtual
machine with x number of vCPUs and y GB of RAM. But how will the administrator
take notice if the resources fulfill the requirements of the virtual machine or if sizing
is totally overprovisioned? This is where a deep analysis comes into play. It can be
analyzed using various values, where the corresponding information for resource
optimization is then displayed. For a too high number of unnecessary vCPUs can be
a performance problem on the respective host system, too. Additionally, we must
always bear in mind that a virtual machine is rarely alone – it has as many systems
that can be deployed on the physical host without interfering with each other. Thus
although it may not be directly relevant, an optimally configured resource impacts
the overall infrastructure.
The added value of an analysis in automation is to screen information on system
configuration and measure the results against predefined rules. The administrator
can, of course, check such items manually against best practice recommendations.
However, this can be daunting due to the size and complexity of some
infrastructures and is also quite error-prone. According to best practices, more
components are evaluated and recommendations are made depending on the
current version. In the virtual environment, attention should be paid to how storage
and network components work together. Another popular theme is whether
clusters are uniformly configured. Through a deep analysis, the administrator wants
to be preventively informed. This also enables the ability to respond before an error
to avoid breakdowns and lags in productivity. Once you imagine that up to 512
virtual machines are supported per physical host (of course a very symbolic number),
the need to operate optimally becomes clear.
In the meantime, applications that are always running, such as SAP, Microsoft
Exchange, SQL, SharePoint, Tomcat, etc., are critical to the business. But often the
request is only for a virtual machine, without the knowledge of what might be
running. In this situation, how can a virtual machine be configured optimally for the
request? Usually not with the default values, which are at times just clicks through a
6. A deep analysis of virtual infrastructures & monitoring 6
wizard. Often it's the little things that matter, like the right selection of a virtual
network card or the correct SCSI controllers in the virtual machine.
3.3 How to respond when problems arise
The administrator receives information that an event has occurred through the
monitoring system, which must then be routed to troubleshooting. Given the large
number of complex components that are used in a virtual infrastructure,
troubleshooting is often quite difficult. Is it just storage latency problems or even
misconfigured MTU sizes on the switches? There are several tools to support the
administrator In the VMware environment. Esxtop is one popular tool. However,
using it effectively requires some know-how, especially when interpreting thresholds.
The site administrator therefore usually relies on their own initiative. What’s more,
an immediate or timely solution is needed.
The in-depth analysis is different in relation to monitoring in the way that problems
that are encountered are treated. A CPU utilization problem of a virtual machine at
100% is displayed and reported, but the administrator doesn’t have the information
on why this CPU problem has occurred. In many cases, CPU limits are set in the VM
configuration temporarily, and then removing the limit is forgotten. Thus, in-depth
analysis combines a monitoring system with an appropriate expert system.
A new approach for in-depth analysis includes tools such as opvizor.
As Andreas Peetz, vExpert and blog author (http://www.v-front.de) said:
"Opvizor lets you run health checks and predictive analyses in a fully automated way.
These are derived from up-to-date rules that are centrally provided by notable
virtualization experts. Based on these "cloud rules" you can e.g. create weekly
reports that are available anytime, anywhere. This way the virtualization admin is
enabled to act preventively, but without burdening himself with maintaining
complex software, because that is implemented as a real cloud service. Only one
small local agent is needed in your environment. In a nutshell opvizor helps to avoid
many issues and outages and makes the administrator's job easier and much more
efficient. This software is definitely worth an investment!"
ALL A QUESTION OF THE CORRECT ANALYSIS
4. A Question Of Correct Analysis
It is not always easy to find THE solution for excellence for a given infrastructure.
However, you have to consider how individual software products work together best
in the area of in-depth analysis and monitoring and also what gives the administrator
a secure feeling (see also fig. 2).
Thanks to Big Data, sufficient meta-data is usually available from the virtual
infrastructure. However, these need to be properly evaluated and that‘s where in-
depth analysis enters.
7. A deep analysis of virtual infrastructures & monitoring 7
A deep analysis is the guarantee of a high-performance, secure, and error-free
infrastructure. It reduces errors and warnings in the monitoring tools and relieves
the administrator of the troubleshooting burden, allowing time for higher-value
projects.
