It is very difficult for a technician to identify social engineering attacks, as these attacks do not involve any technical tools or any software-coding program. A social engineering hacker attempts to persuade users to provide information that will enable him to use their computers or computer resources. Many technicians think that such attacks are a cause of concern only for large organizations. It used to be the case earlier, but now hackers target all sectors.

NTLM version 2 is an enhanced and most secure form of challenge/response authentication. NTLM version 2 uses 128-bit encryption. It significantly improves both the authentication and session security mechanisms. NTLM 2 has been available for Windows NT 4.0 since Service Pack 4 (SP4) was released, and it is supported natively in Windows 2000 and Windows 2003 operating systems. All client operating systems developed by Microsoft after Windows 2000 Professional support NTLM version 2.

What is ICMP?

July 8th, 2009

Internet Control Message Protocol (ICMP) is an integral part of IP. It is used to report an error in datagram processing. The Internet Protocol (IP) is used for host-to-host datagram service in a network. The network is configured with connecting devices called gateways. When an error occurs in datagram processing, gateways or destination hosts report the error to the source hosts through the ICMP protocol. The ICMP messages are sent in various situations, such as when a datagram cannot reach its destination, when the gateway cannot direct the host to send traffic on a shorter route, when the gateway does not have the buffering capacity, etc.

June 26th, 2009

Kerberos v5 is an authentication method used by Windows operating systems to authenticate users and network services. Windows 2000/2003 and XP clients and servers use Kerberos v5 as the default authentication method. Kerberos has replaced the NT LAN Manager (NTLM) authentication method, which was less secure. Kerberos uses mutual authentication to verify both the identity of the user and network services. The Kerberos authentication process is transparent to the users.
