Android will be targeted by malwares in 2010 : Kaspersky

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

Year 2009 was proved to be a great year for Android but according the Kaspersky, 2010 could be a challenging for Android just not because of a lack of awesome devices or not because Android OS won’t move forward significantly,. But it’s the hackers who are expected to target Android users with malwares and viruses.

“Currently the rules are very simple, you pay $25 dollars and your program gets posted, and Google does not do anything to check or manage this process. This is a serious weak point for the platform at this point,” Aleks Gostev stated. “There’s already malware for Android so the appearance of new malware is just a matter of time, not technology.”

Gostev says that Google will need to address the problem as a priority, but that it won’t be easy.

Aside from third-party application Android vulnerability, Kaspersky Lab predicts that 2010 will see Google Wave become a target for cybercriminals as well. Other threats high on their list include mobile malware, not just for Android devices, but also the iPhone along with more peer-to-peer (P2P) and torrent attacks.


From a Kaspersky Press Release issued couple of weeks back

“An increase in attacks on iPhone and Android mobile platforms. 2010 promises to be a difficult time for iPhone and Android users. The first malicious programs for these mobile platforms appeared in 2009, a sure sign that they have aroused the interest of cybercriminals. The only iPhone users currently at risk are those with compromised devices; however the same is not true for Android users who are all vulnerable to attack. The increasing popularity of mobile phones running the Android OS combined with a lack of effective checks to ensure third-party software applications are secure, will lead to a number of high-profile malware outbreaks.”

How to abort a Ping sequence in a Cisco Device?

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

Imagine you are trying to ping a device from your Cisco Switch or a Cisco Router, but by mistake you type a wrong IP address, instead of waiting for the device to give a request time out you can about the ping sequence in your Cisco Device by pressing <CTRL-SHIFT-6> twice in succession. The Cisco Switch or a Cisco Router mentions there is an escape sequence, but doesn’t tell you what it is!

From above picture notice that the ping sequence stopped at 3rd packet.  -5 packets is the default. This combination works for trace route as well pings, both extended and regular.

Disable Cisco Discovery Protocol on unused interfaces

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

We all know how important a Cisco Discovery Protocol (CDP) to troubleshoot the network, but sometimes this may leads to a problem. These days lot of free CDP discovery utilities is available. Anyone can download the CDP utility and start gathering info about your network. It’s always recommended to disable the Cisco Discovery Protocol (CDP) on all the interfaces in your Cisco devices. The only interfaces need to use the Cisco Discovery Protocol (CDP) are the ones which are connected to your Cisco Routers and Cisco Switches. Cisco Discovery Protocol (CDP) can be disabled by using “no cdp enable” command in the entire interface you need.

In my access Switch the CDP is enabled in all interfaces, you can determine this by using a command “show cdp interfaces” you can see CDP is enabled in  all the interfaces.

ITKE-AS01#sho cdp interfaces

FastEthernet0/1 is down, line protocol is down

  Encapsulation ARPA

  Sending CDP packets every 60 seconds

  Holdtime is 180 seconds

FastEthernet0/2 is down, line protocol is down

  Encapsulation ARPA

  Sending CDP packets every 60 seconds

  Holdtime is 180 seconds

FastEthernet0/3 is up, line protocol is up

  Encapsulation ARPA

  Sending CDP packets every 60 seconds

  Holdtime is 180 seconds

FastEthernet0/4 is down, line protocol is down

  Encapsulation ARPA

  Sending CDP packets every 60 seconds

  Holdtime is 180 seconds



FastEthernet0/12 is down, line protocol is down

FastEthernet0/24 is up, line protocol is up

  Encapsulation ARPA

  Sending CDP packets every 60 seconds

  Holdtime is 180 seconds




Let’s see to which interface the router is connected

ITKE-AS01#show cdp neighbors

Capability Codes: R – Router, T – Trans Bridge, B – Source Route Bridge

                  S – Switch, H – Host, I – IGMP, r – Repeater, P – Phone,

                  D – Remote, C – CVTA, M – Two-port Mac Relay


Device ID        Local Intrfce     Holdtme    Capability  Platform  Port ID

MOHMPLS          Fas0/24          176            R       2620XM    Fas 0/0



Let’s disable the CDP in all the interfaces expect fast Ethernet 0/24


ITKE-AS01#configure t

ITKE-AS01(config)#interface range fastEthernet 0/1 -23

ITKE-AS01 (config-if-range)#no cdp enable


In the above example I have disabled CDP in all interfaces except the one connected to the router.

Cisco AP 500 Series Wireless Access Points good for Small Business

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

Cisco Systems launched recently a Wireless access point targeting the Small to Midsize business. The Cisco AP 500 Access Point is easy to install and manage.  The clustering technology with simplifies the deployment and of Cisco AP 500 AP by creating single point of administration for multiple Cisco AP 500 Access Points. Currently Cisco is offering one model AP 541.


The Cisco AP 500 comes with clustering technology, Gigabit Ethernet LAN interface for higher throughput, 802.11n compliance and dual band user selection for either 2.4 GHz or 5 GHz and more over it supports voice roaming.


Some of the features of Cisco AP 500 are as follows

Cisco AP 500 Series Wireless Access Points offer a range of features:

  • Clustering Technology: Simplifies wireless deployments by creating a single point of administration for multiple access points. Clustering technology replicates a configuration, pushes it out to other access points, and continuously manages the frequency channels for each device, reducing network interface.
  • Superior Performance: Gigabit Ethernet LAN interface for higher throughput. Wireless radio complies with 802.11n wireless technology, using MIMO technology to enhance network coverage, capacity, and throughput for data and multimedia applications, while allowing for backward compatibility with a, b, and g clients.
  • Robust Security: Supports business-class security encryptions (WPA2, 802.1x supplicant) and authentication for client compatibility, MAC address authentication, client isolation, and rogue access point detection.
  • Voice Roaming: Allowing for client fast roaming while maintaining good voice quality with 802.11i pre-authenticated standards.
  • Power Options: Uses both standard AC power and Power-over-Ethernet (PoE), simplifying installations in locations such as drop ceilings where power outlets may not be accessible.
