Which mobile iPhone, blackberry or Samsung is best for business use

  By Admin | December 18, 2011 - 1:01 pm | Cool Tips Leave a comment

Every one has their own choice for their mobile. But i write here to discuss on their differences for business use and let users decide.

Why Blackberry?

1.Battery Life
IPhone has a much shorter battery life (not even 12 hours with 3G) than Blackberry.

2.Change of Email Password is not an issue in Blackberry Whenever email password is changed, it has to be manually updated in iPhone and Samsung to continue receiving emails.
If the user is away from office and his email password is expired, then he has to set a new password using OWA (Outlook Web Access) and manually update it in iPhone and Samsung to continue receiving emails.

3.Meeting Request
Even if you have already accepted or declined a meeting request through your desktop outlook, iPhone still shows you option to accept or decline a meeting as if you have not responded to the meeting. IPhone doesn’t allow adding comments to accept or deny meeting requests.

4.Blinking red light is the best notification system for email It’s not easy to say when you have new email in iPhone.

5.Typing keyboard is so easy to write emails compared to virtual keyboards. Auto correction is really annoying in iPhone

6.Sent Folder
The Sent Folder in iPhone is not synched in real time, so you have to wait for the server to find if important business email is sent or not.

7.Security Corporate Blackberry policy can be established If Blackberry is stolen or lost, data theft can be avoided by remote wipe feature.

8.Fixed cost
iPhone and Samsung uses GPRS to download emails, so the internet cost would be dependent on email size download, whereas blackberry service cost is fixed irrespective of size of email downloads

9.Blackberry Messenger

Why iPhone and Samsung?

1.No need for Blackberry Enterprise Server Emails are downloaded through GPRS. If Wi-Fi is available, emails can be downloaded at no cost. 2.Attachment files are more readable than in Blackberry
3.Pinch-to-zoom and high resolution screen.

IDM or ASDM JAVA Memory Heap Size Issue

  By Admin | December 17, 2011 - 7:02 pm | Uncategorized Leave a comment

When trying to open Intrusion Prevention from Cisco ASDM, following message is thrown

image

Your current Java memory heap size is less than 256 MB, the amount required for IOS IPS to run. To change the Java memory heap size, open the Java control panel and enter -Xmx256m in the Java Applet Runtime Settings dialog. This dialog is in the Java tab, or in the Advanced tab of the Java control panel. After you have changed the Java heap size, restart Cisco SDM.

Solution:

Step 1:
1. Open the Control Panel.
2. Navigate to Programs, and open the Java control panel.
3. Under the Java tab, in the Java Runtime Environment Settings pane, click View.
4. For all enabled Java versions, enter -Xmx512m under Runtime Parameters.
5. Hit OK and close the control panel.

Step 2: The shortcut will still refer to its own runtime parameters. Change it and create a short cut as Target: C:\Windows\System32\javaw.exe -Xms256m -Xmx512m -Dsun.swing.enableImprovedDragGesture=true -classpath lzma.jar;jploader.jar;asdm-launcher.jar;retroweaver-rt-2.0.jar com.cisco.launcher.Launcher

Start in: “C:\Program Files\Cisco Systems\ASDM\”

JBoss Worm Perl.Bossworm Infection

  By Admin | November 21, 2011 - 11:16 pm | Firewall, Hacking, My Lab, Scripts Leave a comment

Let me provide you some of the my network analysis and IPS reports, soon after I found that my test JBoss Server has been infected by Perl.Bossworm.

Perl.Bossworm is a malignant worm that exploits the JBoss Enterprise Application Platform Multiple Vulnerabilities (BID 39710) in order to copy itself to unpatched JBOSS servers. When Perl.Bossworm sets up to a vulnerable server, it finds and infects more vulnerable servers. Perl.Bossworm connects to predetermined domains for downloading and installing other malware threats. Remove Perl.Bossworm before it harms your PC system.

How to find out JBoss Worm Infection on your network :-

Perl.Bossworm symptoms on JBoss Server is discussed and very well explained  in JBoss Community. Where as, below are the symptoms on the network side from my lab:

Symptom 1:

  • the connectivity  between Network Switch and Firewall would be very unstable. I had frequent disconnections – request timeout even when I ping the Inside interface of Firewall from the Switch Telnet console. So obviously, you will have either slow Internet connection or no connectivity at all.
Telnet to your Network Switch and ping to Inside LAN interface of Firewall to check the response (PING) status.
Symptom 2:
  • Network Switch utilization has gone up and reached 99% :(
Commands to execute and verify on Network Switch:
1. sh proc cpu sorted (Cisco Switch Command)
You could see that my switch utilization has gone very high within 5 seconds statistics
2. show platform cpu packet statistics  (Cisco Switch Command)
Port GI 7/9 on Network Switch is where JBoss Server was connected, finally found to be transmitting huge number of packets in few seconds

Firewall and IPS (Intrusion Prevention System) Worm Infection Report:-

The IPS reports shown below will clarify the doubts of what has really caused to utilize so high CPU of Network Switch and Firwall disconnectivity

  • The next day after worm infection,  it has established nearly 17000 irc-base sessions to Outside Internet.

  • 342 GB of Bandwidth has been utilized on day 2 of infection
  • Finallywe have the IRC IPs to which infected JBoss server was communicating
