pgp Key Signing Observations: Overlooked Social and Technical Considerations  15 February 2006  Print E-mail
User Rating:      How can I rate this item?
Source: Atom Smasher - Posted by Atom Smasher   
Features While there are several sources of technical information on using pgp in general, and key signing in particular, this article emphasizes social aspects of key signing that are too often ignored, misleading or incorrect in the technical literature. There are also technical issues pointed out where I believe other documentation to be lacking. It is important to acknowledge and address social aspects in a system such as pgp, because the weakest link in the system is the human that is using it. The algorithms, protocols and applications used as part of a pgp system are relatively difficult to compromise or 'break', but the human user can often be easily fooled. Since the human is the weak link in this chain, attention must be paid to actions and decisions of that human; users must be aware of the pitfalls and know how to avoid them.

Source: Suhas Desai - Posted by Benjamin D. Thomas   
Features In this paper, we describe and analyze a network based DoS at¬tack for IP based networks. It is known as SYN flooding. It works by an attacker sending many TCP connection re¬quests with spoofed source addresses to a victim's machine. Each request causes the targeted host to instantiate data structures out of a limited pool of resources to deny further legitimate access.

IPv6 approach for TCP SYN Flood attack over VoIP, Part IV  12 January 2006  Print E-mail

Source: Suhas Desai - Posted by Benjamin D. Thomas   
Features Service Providers are scrambling to offer voice, video, data and innovative services such as gaming, interactive TV and messaging, on a single pipe. At the same time, network equipment is being upgraded to IPV6.But some Real-Time IPV6 Security overwhelms performance due to the application intelligence which is the rapid inspection of VoIP signaling SIP, H.323 and audio packets, and the prompt opening and shutting of "pinholes" to allow the passage of valid voice traffic over wireless networks.

Source: Dancho Danchev - Posted by Pax Dickinson   
Features Malware has truly evolved during the last couple of years. Its potential for financial and network based abuse was quickly realized, and thus, tactics changed, consolidation between different parties occurred, and the malware scene became overly monetized, with its services available on demand.
