Few answers after McAfee antivirus update hits Intel, others Posted: 22 Apr 2010 09:00 AM PDT After distributing a buggy antivirus update that apparently disabled hundreds of thousands of computers on Wednesday, McAfee is still at a loss to explain exactly what happened.

Bank theft Trojan aims at Firefox users Posted: 22 Apr 2010 09:00 AM PDT The world's most feared banking Trojan, Zeus, is going after Mozilla Firefox users for the first time, security company Trusteer has reported.

Recovering from the Flawed McAfee Update Posted: 22 Apr 2010 09:00 AM PDT Nothing ruins an IT administrator's day faster than a software update from a security vendor wreaking havoc on the computer systems it is intended to protect. That is exactly the predicament faced by many IT administrators today when a flawed McAfee update rendered Windows XP PC's essentially useless.

ValidSoft tackles problem of credit-card blocking Posted: 22 Apr 2010 09:00 AM PDT ValidSoft is pushing forward with software it says banks can use to avoid unnecessarily blocking credit card transactions, an occasional frustration for travelers outside of their home country.

How investigators work to combat data theft Posted: 22 Apr 2010 09:00 AM PDT Financial institutions once considered fraud a given risk, but also a small nuisance. Today, stopping fraud is a front-and-center priority for banks and lenders

Routing Protocols Overview Posted: 22 Apr 2010 08:15 AM PDT There are different techniques and methods for maintaining accurate routing information, thus different types of routing protocols were invented over the years. The following post is intended to offer you an overview of the different types of routing protocols currently available. Distance Vector / Link State The above terms refer to the algorithms that govern the exchange of routing information and the way the optimal path is identified. Distance vector protocols exchange information previously incorporated in the device's routing table. The routers know only their immediate neighbor (one hop away). The link-state algorithms on the other hand, exchange information regarding the status of the links in the whole network topology (they have a bigger picture of the network). Distance vector protocols require less hardware resources, but are sensitive to the formation of routing loops. Link state protocols require more hardware resources but are more efficient and converge better. The following are distance vector protocols: RIPv1, RIPv2, IGRP, EIGRP. The following are link-state protocols: OSPF, IS-IS. Classless / classful. Classful protocols publish only the address information of the destination network, not the subnet mask, which forces the device receiving the update to assume that the subnet mask is the same as that on its interface, or the default mask that corresponds to the class. Classless routing protocols however, advertise the subnet mask together with the network address, so the receiving router has full routing information. This allows the implementation of VLSM and CIDR. Classful protocols: RIPv1, IGRP. Classless Protocols: RIPv2, EIGRP, OSPF, IS-IS. Internal Routing Protocols / External Routing Protocols. The interior routing protocols (or IGP – Interior Gateway Protocols) are designed to operate within the same administrative domain, which means that each device is "confident" about the information received from others. Exterior routing protocols (or EGP such as BGP), however, are used to manage routing between different administrative domains. In EGP, each administrative domain is independent. It has implemented its own routing policy. Interior routing protocols: RIPv1, RIPv2, EIGRP, OSPF, IS-IS. Exterior Routing Protocol: BGPv4.

Flawed McAfee update paralyzes corporate PCs Posted: 21 Apr 2010 09:00 AM PDT A flawed McAfee antivirus update sent enterprise administrators scrambling today as the new signatures quarantined a crucial Windows system file, crippling an unknown number of Windows XP computers.

Norton Internet Security 2011 public beta Posted: 21 Apr 2010 09:00 AM PDT As protections against garden-variety viruses and malware have become more effective, malware writers have turned to new ways to infect computers in the pursuit of profit. Two increasing threats are malware spread via bad Facebook links and so-called scareware -- malware that masquerades as virus-scanning software.
