Welcome to the Network Security website at the IAS

This website is intended to bring you the latest news, how to's, tools and resources in Information Security.  Security Awareness of our Faculty, Members and Staff is key in creating a safer computing environment.

The three major Principles of Information Security, Availability, Integrity and Confidentiality, will be covered throughout the security awareness program at the Institute.  For a description of these principles, please see our About section.

In keeping with the spirit of the Institute, I encourage questions and open discussions about security.  And if you discover anything out of the ordinary, please feel free to bring it to my attention so that we can work together to create a more productive, safer environment.

Thanks,
Brian Epstein <security@ias.edu>

"Secunia Research has discovered a vulnerability in OpenOffice.org,
which can be exploited by malicious people to potentially compromise
a user's system.

The vulnerability is caused by a boundary error when parsing certain
records and can be exploited to cause a heap-based buffer overflow via
a specially crafted document.

Sun Solaris 'sockfs' Kernel Module Remote Denial of Service Vulnerability

http://www.securityfocus.com/bid/36169

"Sun Solaris is prone to a remote denial-of-service vulnerability
because of an error in the 'sockfs' kernel module.

Exploiting this issue allows attackers to cause a panic in a vulnerable
Solaris webserver and the system as a whole, effectively denying service
to legitimate users.

This issue affects Solaris 10 and OpenSolaris based on builds snv_41 or
later."

The latest Mac OS X update Snow Leopard is released today. Several faux
update sites have cropped up in the last week offering a pre-release of
Snow Leopard.

Users who visited the sites will install a Trojan DNS changer called
OSX_JAHLAV.K.

Trend Micro Smart Surfing for Macs is able to detect and block this
trojan from installation.

RSA revealed that the majority of breaches are actually caused unintentionally by employees.

http://news.bbc.co.uk/2/hi/technology/8215467.stm

This is an interesting article revealing some research by RSA on insider attacks.  Although malicious insider attacks are high, 19%, the majority of insider attacks are believed to be unintentional, 52%.

"The figures are hard to quantify, but the average annual financial loss to insider risk adds up to $800,000 (£480,000) overall per organisation in the US and between $300,000-$550,000 (£180,000-£330,000) in the UK, France and Germany."
