How to configure Secure Copy (SCP) in Cisco Devices?

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

In my previous post I was talking about the Secure Copy (SCP) what is it?  , now let’s see how to configure Secure Copy (SCP) in a Cisco Router or a Switch.

In order to configure Secure Copy (SCP) in a Cisco Router make sure the SSH is enabled and its working.

Step 1) Lets enable the SSH and AAA features in the Cisco Device

 

ITKE-AS1(config)#ip domain-name itke.com

ITKE-AS1(config)#crypto key generate rsa general-keys modulus 512

The name for the keys will be: ITKE-AS1.itke.com

 

% The key modulus size is 512 bits

% Generating 512 bit RSA keys, keys will be non-exportable…[OK]

 

ITKE-AS1(config)#

ITKE-AS1(config)#aaa new-model

ITKE-AS1(config)#aaa authentication login default local

ITKE-AS1(config)#aaa authentication exec default local

 

Step 2) In order to use the SCP feature to manage configuration we must have at least once user account with enough privilege to access it

ITKE-AS1(config)#

ITKE-AS1(config)#username itke privilege 15 password secret itkeleads

 

Step 3) Now you are ready to enable the SCP server on:

ITKE-AS1(config)#ip scp server enable

 

 

Just by following these 3 simple steps we can enable Secure Copy (SCP) in a Cisco router or a Switch. For any further clarifications you can always have a close look at Cisco’s document on Secure Copy (SCP).

Fortinet October ’09 Threatscape Report Shows Highest Malware Levels Detected all Year

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

According to the latest Threatscape report (October 2009) released by Fortinet, the total amount of malware detected is more than a year, with levels four times greater than in the previous month (September 2009).

The two main Bredolab variants detected this month were W32/Bredo.G and W32/Bredolab.X, most notably included in fake DHL invoice spam campaigns.

Derek Manky, project manager, cyber security and threat research, Fortinet commented: “We’re seeing record levels of scareware building off volume from September, and the danger in these threats is only becoming more serious as the methods for delivery evolve and the blending of attacks bring more complexity.
“As we’ve seen in the consistency of repeated threats, the old schemes are still proving to be good methods. Enterprises and consumers must take equal responsibility in understanding the disguises of these threats and implementing a multi-pronged security solution that addresses the different and changing characteristics of tried and true tactics,” he added

During the month of October 2009 Scareware tactics have reached all time high, with worst ever attacks reported. Seven of the top ten malware variants detected linked back to scareware, with scareware tactics diverging to include botnets, corrupted advertisements and SEO attacks.

The most notable development in October 2009 was the preponderance of AntiVirus Pro 2010 rogue security software, which when installed will contact a remote server in order to obtain malicious payload and receive updated copies; a trojan downloader named Bredolab which is now downloading AntiVirus Pro 2010 installers and the ZBot keylogger; and the ongoing development of affiliate programs that tempt participants with a handsome pay-out on each software download purchased. Tools and kits are readily available to participating affiliates, accelerating the distribution of scareware and other malicious components.

What is Secure Copy (SCP)?

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

 

We are all aware of the traditional way of transferring IOS files from and to Cisco Catalyst Switches, Cisco Routers and Cisco PIX/ASA firewall devices using TFPT, FTP and lately https. However there is also one more way to copy the IOS files, which is known as Secure Copy (SCP). The Secure Copy (SCP) is a secure and authenticated method of copying a configuration file or transferring an Image files to Cisco Catalyst Switches, Cisco Routers and Cisco PIX/ASA firewall devices.

 

Cisco Systems introduced the Secure Copy (SCP) feature in the following IOS releases

 

Release

Modification

12.2(2)T

This feature was introduced.

12.0(21)S

This feature was integrated into Cisco IOS 12.0(21)S.

12.2(25)S

This feature was integrated into Cisco IOS 12.2(25)S.

PIX/ASA firewalls 7.1 and above, FWSM 3.1 and above.

  

The Secure Copy (SCP) works on SSH protocol on port 22 which is like an encrypted tunnel. This tool is very useful especially to transfer files for upgrades or to perform safe backups.

 

In my next post you will find the commands to configure SCP in a Cisco Router and Switch.

CCIE Routing and Switching Official Certification Guide to be released in November 2009

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

I was just accessing the rough cuts for the Cisco CCIE Routing and Switching Official Certification Guide, 4th Edition. I had a great first impression. I had a chance to read “LAN Switching” part. It was a great firsthand experience. This segment is organized well and the approach is similar to CCNA, CCNP books, starts with a brief introduction and then the most useful section of Cisco Press Books “Do I Know This Already?” Quiz followed by “Foundation topics and “Foundation Summary”.

The Cisco Press authors Wendell Odom, Rus Healy and Denise Donohue did a credible job; I liked the way they presented the topics, since I spent most of my time on Switching I really enjoyed the “LAN Switching” part. Though I am familiar with most of the things they were talking but it was great experience to refresh my info.

 

The CCIE Routing and Switching Official Certification Guide 4th Edition is to be released on 19th of November 2009 by Cisco Press, they are offering great discount do check Cisco Press web site for more details, but make sure you registered yourself to Cisco Press website to get more discount. Once the book released I will try to write a review on this book.

Windows 7 is amazing in terms of Systems restoration

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

I am using Windows 7, since beta days and then now with RC release.  Couple of week’s back I was attending a Seminar “Introducing Windows 7” organized by Microsoft for their partners. I did asked few questions; one of them was related to Windows restore and hibernation. I asked them if I have a complete Backup of my computer in my external USB hard disk, is it possible to restore Windows 7 and all applications in a new hard disk. The gentleman said it’s not possible. I was not convinced thought of testing myself.

 First using the Systems and Security menu from Control panel I selected the option “Backup your Computer” and I selected I created a System Image in my External USB hard disk.

 

Then I created a System repair disk by using the menu “Create a system repair disk” from the Systems and Security menu from Control panel.

 

Once I am done with these things I replaced the existing hard disk in my laptop with a new one. Then I installed Windows 7 in my laptop, after completion of Windows 7 installation I restarted my laptop with the restore disk I created and I made sure my External USB hard disk is connected my laptop as well. I booted the laptop using the System repair disk and then I click next once I got this menu,

 

And then I selected the option “Restore your computer using a system image that you created earlier”

Then I selected the latest available system image which by default selected the image stored in my external USB hard disk,

 If by change if the latest system image is not shown you always have an option to select the image manually. Once I selected the image file stored in my external USB hard disk I was able to restore my laptop with all applications and documents stored in my original hard disk. Cool utility that too GUI from Microsoft in Windows 7. For some reason I forget to take the backup of my contacts in my Microsoft Outlook 2007 so again I removed the new hard disk and replaced it with the original one. When I restarted the laptop with the original hard disk, the laptop started back from the Hibernation mode. As I forget to shutdown my laptop before starting this whole operation. It was hibernated with lot of open files and windows. Amazing isn’t it.
