BARCLAYS SLAMMED OVER INTERNET SECURITY FLAW
Barclays came under fire from customers and consumer groups today after a
security breach exposed confidential account details. The bank was forced to
shut down its online banking service yesterday evening after a Saturday night
upgrade to the online transaction software left user data accessible to other
account holders.

NORTON PATCHES FIREWALL HOLES
Symantec has quietly modified its Norton Personal Firewall and Norton Internet
Security 2000 products to block advertising programs that are sometimes dubbed
"spyware." The programs, called adbots, fetch banner ads over the Internet, but
they also transmit encrypted data about the user back to the advertising
companies. This function has earned them the "spyware" label among privacy
and security advocates.

BROWN ORIFICE SECURITY HOLE
From Dan Brumleve homepage - "I've discovered a pair of new capbilities in
Java, one residing in the Java core and the other in Netscape's Java distribution.
The first (exploited in BOServerSocket and BOSocket) allows Java to open a
server which can be accessed by arbitrary clients. The second (BOURLConnection
and BOURLInputStream) allows Java to access arbitrary URLs, including local files.
As a demonstration, I've written Brown Orifice HTTPD for Netscape Communicator.
BOHTTPD is a browser-resident web server and file-sharing tool that demonstrates
these two problems in Netscape Communicator. BOHTTPD will serve files from a
directory of your choice, and will also act as an HTTP/FTP proxy server."

E-COMMERCE SECURITY : WEAK LINKS, BEST DEFENSES
Online security investigator and research scientist Anup Ghosh takes a realistic
look at the state of security for electronic commerce. He feels that some levels
of security are excessive. But he emphasizes that any security system is only
as strong as its weakest point. If you're going to trust your money to online
transactions, you need to know where your weaknesses lie and how to correct
them. To that end, Ghosh discusses real-life security failures, how they occurred,
and how recurrences can be prevented. He then takes a systematic look at the
areas of risk. One chapter deals with potential problems in active Web content,
such as Java applets, ActiveX controls, and push technology. He examines data
protocols to secure transactions with the warning that the data can be
vulnerable before and after the secure transmission. The weaknesses of server
hardware and software come under scrutiny as well. Ghosh calls for greater
attention to security as software is being developed and looks at what
advances are likely to be coming down the road.

HACK PROOFING YOUR NETWORK: INTERNET TRADECRAFT
Systems and software packages are being connected to the internet at an
astounding rate. Many of these systems and packages were not designed with
security in mind. IT professionals need to keep their systems secure: this book
shows them how to make a meaningful security assessment of their own
systems, by thinking like a hacker. Using forensics-based analysis this book
gives the reader insight to the mind of a hacker. About the Author - Ryan
Russell is MIS Manager at SecurityFocus.com. He has served as an expert
witness on security topics and has done internal security investigation for a
major software vendor. Ryan has contributed to three Syngress Media books,
on networking topics. He has a degree in computer science from San Francisco
State University.

INTRUSION DETECTION: AN INTRODUCTION TO INTERNET SURVEILLANCE,
CORRELATION, TRACE BACK, TRAPS, AND RESPONSE
The book presents the details and methodologies associated with intrusion
detection technology to control cracking activity on the Internet. Topics
include commercial tools, strategies for processing security audit trails,
correlation techniques and algorithms, intruder trace back techniques,
deception-based honey pots and traps, and incident response and disaster
recovery.

----------------------------------------------------------------------------
IPSEC: THE NEW SECURITY STANDARD FOR THE INTER- NET, INTRANETS,
AND VIRTUAL PRIVATE NETWORKS
Authors Doraswamy and Harkins first treat IPSec as a system, explaining how
its component parts work together to provide flexible security. Their approach
to this task makes sense: They first explain why standard IP packets aren't
secure; then they show how the IPSec improvements make secure transactions
possible. Readers get full descriptions of how various network entities talk to
one another. Where appropriate, concepts that aren't specific to IPSec are
explained, including IPv4 and IPv6 packet structures and addressing schemes.
There's some information on cryptography too. IPSec's parts are explained
individually: the Authentication Header (AH), Encapsulating Security Payload
(ESP), Internet Key Exchange (IKE), and ISAKMP/Oakley protocols are detailed
with lots of prose, supplemented with a smattering of packet diagrams and
conceptual sketches. Sections on implementing IPSec protocols on networks
remain fairly abstract and don't mention actual products, but should prove
useful to programmers designing their own network security products around
the IPSec specifications.

PROGRAMMING WINDOWS SECURITY
Topics covered include: COM(+) security, from the ground up IIS security How
the file system redirector works and why developers should care The RPC
security model Kerberos, NTLM, and SSL authentication protocols and SSPI
Services and the Trusted Computing Base Logon sessions and tokens Window
stations, desktops, and user profiles The Windows 2000 ACL model, including
the new model of inheritance Using private security descriptors to secure
objects Accounts, groups, aliases, privileges, and passwords Comparison of
three strategies for performing access control - impersonation, role-centric,
and object-centric - and their impact on the design of a distributed application
Programming Windows Security provides the most comprehensive coverage of
COM(+) security available in one place, culled from the author's extensive
experience in diagnosing COM security problems in the lab and via
correspondence on the DCOM mailing list.
