Cisco Switching Products Posted: 08 Jul 2011 12:28 PM PDT Cisco Systems Inc. supports a broad range of local area network (LAN) switching architecture technologies and platforms.  The general minimal requirements that the Cisco switching platforms are designed to address include the following: High-performance switched Ethernet, capable of delivering 100 Mbps and 1Gbps to the desktop, and 1Gbps or 10Gbps uplinks. Quality of Service (QoS) features permitting prioritization of delay-sensitive traffic and control over packet delay and jitter. Simple, highly structured, and deterministic design (Predictable – in both normal and failure recovery modes). Support for both IP version 4 and IP version 6 protocols. Fault tolerance (Redundancy for critical components and links ‑ eliminating network single-points-of-failure). Flexibility (Network logically partitioned at Layers 2, 3 and 4, to direct traffic flow). Secured through authentication, authorization and accounting (AAA) controls. Modular design capable of supporting new applications and network growth without requiring "fork-lift" upgrades. Scalability for cost-effective delivery of the smallest to the largest telecommunications rooms and campuses Multicast protocol support for end-to-end management and optimization of streaming content delivery. Switches capable of powering IP telephones (via phantom power). Capable of being remotely monitored and managed using network management tools, such as HP Openview. All Cisco switches are based on a distributed hardware architecture in which the LAN switching functions are separated from the "control plane" functions of switch management by utilizing both one or more general-purpose central processing chips and port or line card application-specific integrated circuits (ASICs). The general-purpose CPU handles network management functions, like user logins, SNMP, and maintenance operations like operating system booting.  The general-purpose processor controls the configuration of the switch platforms with a command-line interface.  The ASICs optimize packet and frame switching at the port and line card level in order to reduce inter-frame delays and increase overall system throughput. Older Cisco switches used an operating system called CatOS, with a command-line syntax based on set and clear statements.  Newer switch use an operating system referred to as the Cisco Internetwork Operating System (IOS), which is common across both switching and routing platforms.  The older CatOS is end-of-life and end-of-sale.  Only configurations involving IOS will be shown here.  A newer switching operating system based on the Cisco next-generation Nexus platforms is called NXOS, but is nearly identical to the IOS command syntax, and most of the Cisco switch product is based on IOS. Cisco switching utilizes recommendations for a hierarchical design in switched network infrastructures, called core, distribution, and access layers.  It is acceptable to combine the functions of the core and distribution layers in smaller switched networks, which is called a collapsed core design.  The functions of each layer are as follows: Core layer Links to WAN (Internet or other wide-area network) Links to distribution switches Additional Virtual Local Area Networks (VLANs) —Used by the system for routed ports as well as WAN ports Distribution Layer Server connections Links to downstream (closet) access switches via layer 2 or layer 3 links. Site services, like wireless LAN controllers Service VLANs—To forward traffic to the service modules, such as the client VLAN of a content switch Fault tolerant VLANs—For redundancy with CSM, FWSM, CSS, and so forth Access Layer Client connectivity at 10/100/1000Mbps

Microsoft beefs up Outlook-to-Hotmail security Posted: 08 Jul 2011 08:01 AM PDT Microsoft on Thursday boosted the security of a tool that lets Outlook users send and receive messages through the company's Web-based Hotmail service.

Aristotle on anonymity Posted: 08 Jul 2011 03:00 AM PDT Way back in 2006 I had a series of newsletters about anonymity. That's when I first tried to separate anonymity from privacy -- but they still keep getting confused to this day.

Who are all these hacker groups? Posted: 08 Jul 2011 03:00 AM PDT Hacker groups that attack or steal—some estimates say there are as many as 6,000 of such groups online with about 50,000 "bad actors" around the world drifting in and out of them—are a threat, but the goals, methods, effectiveness of these groups varies widely.

Visa blocks WikiLeaks donations via DataCell once again Posted: 08 Jul 2011 02:36 AM PDT For a few hours on Thursday, credit card donations once again flowed to WikiLeaks through a payment gateway at Icelandic hosting company DataCell. Then Visa shut it down again.

Anonymous eyes political role, but won't go legit Posted: 07 Jul 2011 08:17 AM PDT Hacker group Anonymous plans to promote an affiliated political party to attract people who share its civil liberties goals, but do not agree with its methods.

UCLA Medical Center agrees to settle HIPAA violation charges for $865K Posted: 07 Jul 2011 02:59 AM PDT After years of being accused of doing little to enforce HIPAAs security and privacy rules, the U.S. Department of Health and Human Services appears to be finally getting serious about cracking down on offenders.

UK's News of the World closes after phone hacking scandal Posted: 07 Jul 2011 12:29 AM PDT The U.K.'s News of the World is closing admit allegations of staff members hacking into the mobile voice mail of celebrities and crime victims.

Microsoft plans 22 patches for Windows, Office next week Posted: 07 Jul 2011 12:20 AM PDT Microsoft today said it will issue four security updates next week, only one of which is pegged as critical, to patch 22 vulnerabilities in Windows and Visio 2003.

The Latest Security Tool for Your Arsenal: Whitelisting Posted: 06 Jul 2011 11:12 PM PDT Phishing, spear phishing, trojan horse and other attacks are growing in number and sophistication, seemingly by the day. There can be little disputing that notion after RSA, Sony, Lockheed and Citicorp were embarrassed by breaches this year.

PDFs that exploit iPhone, iPad zero-day available on the Web Posted: 06 Jul 2011 10:15 PM PDT German government security officials warned that one of the recently revealed Apple iOS flaws could be put to malicious use.
