2013 Gartner Magic Quadrant for Enterprise Network Firewalls

Figure 1. Magic Quadrant for Enterprise Network Firewalls

 

The enterprise network firewall market represented by this Magic Quadrant is composed primarily of purpose-built appliances and virtualized models for securing corporate networks. Products must be able to support single-enterprise firewall deployments and large global deployments, including branch offices. These products are accompanied by highly scalable management and reporting consoles, products, and a sales and support ecosystem focused on the enterprise.

The firewall market has evolved from simple stateful firewalls to NGFWs, incorporating full-stack inspection to support intrusion prevention, application-level inspection and granular policy control. Such NGFWs will eventually subsume mainstream deployments of stand-alone network intrusion prevention system (IPS) appliance technology at the enterprise edge. Gartner already sees this shift in the form of reduced IPS buying activity and a flattening of IPS market growth, but Gartner believes the security-conscious segment of the market will continue to use separate IPSs. The reality of product life spans cannot be ignored in this market shift, however: Enterprises refresh individual firewalls, on average, every five years, and IPSs are refreshed about four years or less, so the market won’t shift quickly.

Although firewall/VPN and IPS are converging, other security products are not. All-in-one or unified threat management (UTM) products are suitable for small or midsize businesses (SMBs) but not for the enterprise: Gartner forecasts that this separation will continue until at least 2016. Branch-office firewalls are becoming specialized products, diverging from the SMB products (for more information, see “Magic Quadrant for Unified Threat Management”).

Gartner has successively increased the Magic Quadrant evaluation weighting for NGFW features. This edition signals a significant increase in the weighting of NGFW capabilities reflecting the changing markets and enterprise needs.

Nagios Core Administration Cookbook

Language : English
Paperback : 360 pages [ 235mm x 191mm ]
Release Date : January 2013
ISBN : 1849515565
ISBN 13 : 9781849515566
Author(s) : Tom Ryder

  • Monitor almost anything in a network
  • Control notifications in your network by configuring Nagios Core
  • Get a handle on best practices and time-saving configuration methods for a leaner configuration
  • Use the web interface to control notification behaviour on the fly and for scheduled outages, without restarts
  • Pull Nagios Core’s data into a database to write clever custom reports of your own devising

What you will learn from this book

  • Finding, installing, and writing your own plugins, and learning to reference them as Nagios Core commands for use as host and service checks, including workarounds for making checks through difficult network layouts such as those using Network Address Translation.
  • Managing notifications to send the right kind of notifications to the right people at the right time, and defining contact methods besides simple email messages, including an example of automatic contact rotation.
  • In-depth examples of using the standard set of Nagios Plugins for common network monitoring needs, with discussion of generic methods for monitoring the results of SNMP queries.
  • Remote monitoring methods to handle the situations where Nagios Core cannot directly check a service’s status over the network, to check things such as database servers that only listen locally, or hardware devices with no SNMP OIDs exported.
  • Defining network structure and dependencies in Nagios Core to enable it to perform its notification behavior more intelligently, and allow you to very quickly find the “root” of particular problems; also how to reflect this structure in the network map once defined, and even decorate it.
  • Best practices for managing Nagios Core configuration to make it leaner, more robust, and better suited to programatically generating configuration as specified by other systems.
  • Automating other interactions with Nagios Core, including using passive checks to track tasks being performed both locally and in other parts of the network, or running scripts automatically in response to checks; also includes discussion of developing your own reports or vizualisations using automatically exported data from the system.

He uses Nagios Core as part of his “day job” as a systems administrator, monitoring the network for a regional internet service provider. Tom works a great deal with UNIX-like systems, being a particular fan of GNU/Linux, and writes about usage of open source command line development tools on his blog Arabesque: http://blog.sanctum.geek.nz.

Melissa Manchester: Don’t Cry Out Loud

Album: Don’t Cry Out Loud
Year: 1978

(Words by Carol Bayer Sager and Music by Peter Allen)

Baby cried the day the circus came to town
‘Cause she didn’t want parades just passing by her
So she painted on a smile
And took up with some clown
While she danced without a net upon the wire

I know a lot about her
‘Cause you see
Baby is an awful lot like me

Don’t cry out loud
Just keep it inside
Learn how to hide your feelings
Fly high and proud
And if you should fall
Remember you almost had it all

Baby saw that when they pulled that big top down
They left behind her dreams among the litter
The different kind of love she thought she’d found
There was nothin’ left but sawdust and some glitter

But baby can’t be broken
‘Cause you see
She had the finest teacher
That was me, I told her

Don’t cry out loud
Just keep it inside
And learn how to hide your feelings
Fly high and proud
And if you should fall
Remember you almost had it all

Don’t cry out loud
Just keep it inside
And learn how to hide your feelings
Fly high and proud
And if you should fall
Remember you almost made it

Don’t cry out loud
Just keep it inside
And learn how to hide your feelings
Fly high and proud
And if you should fall
Remember you almost had it all…
