So much is written about the events outside your perimeter; those nefarious
and shadowy individuals and offshore syndicates who are looking to steal
technology or personal data or piggyback on your servers to peddle everything
from pirated products to pornography, implant botnets or viruses, or simply
to create corporate chaos. With all that weighing on our collective IT asset
protection strategies, it is easy to miss what a new Carnegie Mellon report
is pointing to as one of the fastest growing threats…insider breaches. Even
KPMG says this threat has tripled since 2007.
They come in all shapes and sizes, former employees who have an axe to grind,
careless users, or outside partners/vendors/suppliers with access to your
proprietary information. The key point is that when you spend so much time
building a wall of protection around your networks, many enterprises fail ... (more)
Advanced malicious content and attacks are starting to threaten conventional
network filtering technologies that are not able to keep up with the
increased volume and complexity of network traffic. Currently, one in every
14 downloads contains malicious content that may create operational,
reputational and customer relationship management challenges. The Global
State of Information Security survey conducted by PwC in 2012 found that 57
percent of security experts are dissatisfied with their information security
strategy. When malware and non-compliant data slip through the networ... (more)
Being a software architect requires keeping up to speed with the hardware and
networking options that are available. I decided to go with this textbook to
brush up on networking.
This book is intended to get you up to speed to take the CompTIA's Network+
exam. Throughout the book the author lists the CompTIA Domain/Objective
Number being covered in the chapter and which section you'll find it.
After a nice introduction to networking chapter the book digs into the
details with chapters Physical Layer Cabling: Twisted Pair, Physical Layer
Cabling: Fiber Optics, Wireless Networking, I... (more)
Most network monitoring programs are based on periodic automatic testing of
the efficiency of particular services, ports, and protocols. The most
widespread method is sending particular ICMP packets to a remote host and
waiting for a reply from it (ping). One of the most important device
parameter considered from the network monitoring point of view is the
device's response time. It allows you to analyze the device operation on the
network and detect possible bottlenecks and failures in the data transfer
process. There are a lot of network monitoring methods, and the choice
dep... (more)
Managing access to confidential information and application resources via
firewalls is the foundation of network security, and firewall audits are
central to any mature network security process. However, relying on security
and network experts to review rules across multiple firewall zones and
different firewall products is proving to be costly and ineffective. Few will
dispute that when it comes to network security, automating best practices to
reduce operating costs, complexity, human error, and streamline processes is
a good thing. However, in what we call the age of Continuou... (more)
