The Cisco 2010 Midyear Security Report examines the major forces of change reshaping the global security landscape. These changes demand that organizations rethink their approaches to enterprise security. Current shifts — from the virtualization of operations to collaboration and social networking — provide new opportunities for criminals to infiltrate networks and steal high-value business data. As more organizations transition to borderless enterprises, criminals are quickly discovering new tactics for breaching network safeguards. Businesses are weighing the benefits of embracing mobility, video, and collaborative applications (such as social networking and peer-to-peer technologies). At the same time, criminals are using the same [...]

Do you remember the “Cisco regular expressions” tutorial? A regular expression is entered as part of a command and is a pattern made up of symbols, letters, and numbers that represent an input string for matching (or sometimes not matching). Matching the string to the specified pattern is called pattern matching. Pattern matching either succeeds or fails. If a regular expression can match two different parts of an input string, it will match the earliest part first. In this tutorial, I will explain how to use the ‘show’ command with the regular expression.

Untrusted search path vulnerability in Cisco Packet Tracer 5.2 allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse wintab32.dll that is located in the same folder as a .pkt or .pkz file. The vulnerability is caused due to the application loading libraries (e.g. wintab32.dll) in an insecure manner. The program uses a fixed path to look for specific files or libraries. This path includes directories that may not be trusted or under user control. By placing a custom version of the file or library in the path, the program [...]
