REMOTE MANAGEMENT OF SYSTEM
PRESENTED BY:

Slide2INTRODUCTION:-
A process where network administrators have remote control of systems
a
llowing users with remote computers to create a logical connection to the internet. This process is possible by remote access which is a set of technologies which connects a computer out of range to the internet
The system is overlooked by a user through SNMP which notifies him about various system based on Microsoft, Cisco
etc
which use the remote management model
Microsoft operating system have sets of applications which enables remote access and security features that an administrator should need in his daily routing
CISCO used remote management model by a software called Cisco Virtual Office which provided support for quality of service (
QoS
) for voice and video, and has flexible security options
Slide3COMPONENTS OF REMOTE NETWORKING MODEL:-
The Microsoft and Cisco used the following components for efficient functioning. They are as follows
Virtualization Platform (virtual computer systems, virtualization layer, and physical NICs)
Attached Bridge
Management Client
Network Port Profile Database (NPPDB)
Slide4COMPONENTS OF REMOTE NETWORKING MODEL:-
Slide5VIRTUALIZATION PLATFORM:-
Consists of emulators and hypervisors that emulate whole physical computer machine providing multiple virtual machines on one physical platform
Allows in virtualized server isolation
Virtual computer is an emulation of a computer system based on computer architectures providing functionality of a physical computer with specialized hardware, software, or both
Platform virtualization refers to the creation of a virtual machine that acts like a real computer with an operating system
Slide6VIRTUALIZATION PLATFORM:-
Software executed on these virtual machines is separated from the underlying hardware resources
Network Interface Controller (NIC) – Computer hardware component that connects a computer to a computer network
Modern NICs offer advanced features such as interrupt and DMA interfaces to the host processors, support for multiple receive and transmit queues, partitioning into multiple logical interfaces, and on-controller network traffic processing such as the TCP offload engine
Slide7ATTACHED BRIDGE:-
A direct attachment of the virtual machine's NIC to the given physical interface of the host physical machine
Packets whose destination is on the same host physical machine as where they originate from are directly delivered to the target device
Both origin and destination devices need to be in bridged mode for direct delivery. If either one of them is in
vepa
mode, a VEPA capable bridge is required
Slide8MANAGEMENT CLIENT:-
Delivers distributed endpoint management (mobile, laptop, desktop, and server), helping IT deliver great service to end-users while minimizing cost, maintaining compliance, and reducing security risks
Make intelligent decisions knowing the current state of inventory
Pass software audits with ease and manage your software entitlements – don’t over deploy and don’t over spend
Reduce vulnerability and financial risk through endpoint compliance and automated software patching
Slide9MANAGEMENT CLIENT:-
Automate system provisioning, application deployment, profile configuration from a single console
Seamlessly drive endpoint troubleshooting and management from BMC service management solutions
Must be available on-demand or on premises
Slide10NETWORK PORT PROFILE DATABASE (NPPDB):-
Slide11NETWORK PORT PROFILE DATABASE (NPPDB):-
Refers to a set of networking attributes for virtual machine(s) • MAC address, VLAN,
QoS
…
Describes a specific configuration of network infrastructure
To which virtual machine gets connected to
Establishes consistent configuration among the bridges
Slide12NETWORK PORT PROFILE DATABASE (NPPDB):-
OVF – DMTF standard for packaging, distributing, and deploying VMs
Network port profile XML schema and OVF provide an interoperable way of provisioning and deploying networks in virtualized
Network Port Profile
configuration is independent from OVF
Slide13SECURITY FEATURES OF MICROSOFT REMOTE ACCESS:-
Microsoft remote access offers a wide range of security features including:
Authentication and authorization
Secure user authentication
Extensible Authentication Protocol
Data encryption
Caller ID
Remote access account lockout
Remote access policy profile packet filtering
Packet filtering for VPN remote access
Slide14SECURITY FEATURES OF CISCO REMOTE ACCESSING:-
Cisco offers wide range of security features such as:
24x7 Threat Analysis and Management
Log Collection and Event Correlation
High Touch Management and Incident Support
Net flow and Metadata Extraction
Proactive Threat Hunting
Full Packet Capture
Slide15PROBLEMS:-
Due to technology advances associated with convergence, consolidation and centralisation across the ICT stack, networks have become increasingly important and complex
COMPLEXITY :
Disparate network elements from multiple vendors need to be managed, along with secure policies, application performance and service levels
COST
: Networking and communications costs are a perennial concern for organisations and one of the most important factors in implementing new services
RESOURCING
: technical expertise could be better used to progress business projects, rather than manage network monitoring and availability issues
RELIABILITY
: Critical business applications and processes are impacted by unpredictable network availability
Slide16CHALLENGES:-
GREATER COMPLEXITY:
Disparate network elements from multiple vendors need to be managed, along with secure policies, application performance and service levels
RELIABILITY / PREDICTABILITY:
Critical business applications and processes are impacted by unpredictable network availability
COST MANAGEMENT:
Networking and communications costs are a perennial concern for organisations and one of the most important factors in implementing new services
Slide17OTHER CHALLENGES:-
Lack of common configuration information that may be referenced by the virtualization ecosystem management entities
Disparity between the capabilities of embedded bridges in the virtualization hosts and the capabilities of bridges in the attached network
Technologies such as WAN optimization voice/video over IP, WLAN Application based policy control have all become an important to network element which oversee the effectiveness on Remote Network Management
Microsoft and Cisco offer various software and hardware tool to enable the effectiveness of an administrator
Slide18SOLUTIONS:-
DEVICE AND VENDOR AGNOSTIC
: A wide variety of networking products from different vendors such as Cisco®, Juniper®, Blue Coat®, Riverbed®,
Adva
™, IPFX®, F5® are added as technology evolves
INCREASED AVAILABILITY:
Greater network availability through 24x7 proactive monitoring and managed problem resolution by a team of networking specialists
INFORMATION AT ALL TIMES:
Near real time information on your network through our 24x7 customer accessible portal
REDUCED COSTS
: Reduce the cost of IT management and the total cost of ownership, allowing your in-house experts to focus on your core business activities
