No doubt that one of the most difficult certification in IT industry is Certified Information System Security Professional (CISSP). This certification will give us globally recognized expertise in the field of Information Security. iSC2 conducting CISSP exam and the details you can see here http://www.isc2.org website.

I am planning to give some of the resources that yo can follow to obtain the CISSP certification. These findings i have got it from different forums and tech community.

There is no dumps available for CISSP exam. Only the way to obtain the certification is to read a few good books and attend some good training which is conducted by iSC2 or any other  third parties.

Please note that below books are the favorites books which i could find in discussion forms in net. There are lot of other books available in the market which you can buy your own interest.

1.CISSP Study Guide, Second/ Third Edition by Eric Conrad

2.CISSP All-in-One Exam Guide, 5th/ 6th Edition by Shon Harris

3.Official (ISC)2 Guide to the CISSP CBK, Second Edition ((ISC)2 Press)

4.CISSP For Dummies 4th edition

5.Eleventh Hour CISSP: Study Guide

Plus you can get some almost real questions & answers from below quiz engine.

1. https://www.freepracticetests.org/ – from cccure.org – online Quiz database – 2500 questions – 49 US $

2. Official (ISC)²® studISCope Self Assessment – costly – but from iSC2 and could see previously asked questions. nearly 300 US $

It will be good if you could able to attend a boot camp from Isc2 or any other third party before attend exam. normally people attending just before exam date, i.e around 2 weeks before the exam.

And iSC2 started computer based exam that you can written from VUE. No more paper exam available now.

Rebuild Index in MS SQL 2008

Filed under: MS SQL Server — Akther @ 4:52 pm
Tags: , , , ,

This post would like to describe how to rebuild indexes in MS SQL 2008 R2.

There are many ways to rebuild indexes in SQL. Here we will see how to use Maintenance Plan tool to rebuild whole indexes in a particular database or whole databases in SQL server instance. It’s simple but need to take care little bit.

SQL Server Management Studio–> Management  –> Maintenance Plans –> Maintenance Plan Wizard

1

 

 

 

 

 

Launch the wizard and click next. Give the Name of the Maintenance Plan wizard. Set schedule if you want to run every week or according to your choice.

2

 

 

 

 

 

 

 

 

 

Click Next and select Check Database Integrity and Rebuild Index tasks.

3

 

 

 

 

 

 

 

 

 

Check Database integrity is an useful choice before do the rebuild because if database has any integrity problem then no need to do the rebuild of index.

One thing you have to notice that Rebuild index task is  high CPU and very I/O intensive and it locks the database resources as well. So better to do this on off business hours.

Rebuild index task will do the update statistics and reorganize task. So no need to select these two tasks if you are doing a rebuild index. It’s a common mistake we could see while using Maintenance Plan Wizard that select all the tasks even if not necessary. It will slow down the performance  of your SQL server.

4

 

 

 

 

 

 

 

 

 

Click Next –> Select which database you want to do the Database Integrity. Or select whole database. This step will repeat to Rebuild index as well.

5

 

 

 

 

 

 

Select the log file location

6

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Next screen will finish the task

7

 

 

 

 

 

 

 

 

 

This task will run based on the schedule you have mentioned. Or you can trigger the task when you want from Maintenance Plan section.

The WordPress.com stats helper monkeys prepared a 2012 annual report for this blog.

Here’s an excerpt:

19,000 people fit into the new Barclays Center to see Jay-Z perform. This blog was viewed about 65,000 times in 2012. If it were a concert at the Barclays Center, it would take about 3 sold-out performances for that many people to see it.

Hyper-V and VHD’s

Filed under: Hyper-V — Akther @ 9:13 am
Tags: , ,

VHD’s provide storage for virtual machines and are stored on physical media as .VHD files.

While creating a new virtual machine we can create VHD’s or can select existing VHD’s which we already created or used. Or we can add a VHD later and can complete the VM creation wizard.

OK. Now i want to give  an additional drive or partition to this VM.

1) Create a VHD from hyper-v console.

2)Attach that VHD from Hyper-V snap-in of VM as additional hard disk from IDE controller 0 or add as second IDE controller, Then add hard drive. ( snapshot below)

3) Or we can add additional SCSI controller from hyper-v settings if IDE controller 0 and 1 are fully used. To do this click add hardware and select SCSI controller

4)Once you add you can see physical disk option. Select disk from drop down list ( this disk should be offline in disk management of hyper-v host server. Other wise we cannot see the disk in this console)

These are the two method we can assign disks to VM’ from hyper-v console of the Hyper-v server. To add any hardware VM must be shutdown. Or from SAN you can directly map the hard disks in to VM’s by using iSCSI initiator in windows.

Adding VHD’s as additional hard disks ( IDE controller)

Dell MD3200i Installation

Filed under: DELL Storage — Akther @ 10:37 am
Tags: ,

In this article we will see how to provision a Dell 3200i iSCSI storage device in network.

This device is a dual controller and having 4 iSCSI ports each controller and 2 managment port for both controller. ( for managing device)

1. Rack Mount the device and connect power. It’s a 2u device and 12 bay slot to add hard disk.

2. Connect two cables from each managment port to one of the server Lan1 and Lan2. To do the initial configuration of storage. by default ip address of managment ports are 192.168.128.101 and 102. Same subnet ip given to LAN1 and LAN2 of the servers.

Installed Dell resource media kit in server ( shipped with device). By using Dell Modular disk manager utility (MDSM) will do the initial configration.

3. Add Storage Array .

Open MDSM from management server where managment port are connected.

 

 

 

 

 

 

 

Below ip addresses are the default management port ip address. We are using out-of-band management method to configure the device. Out of band means using manament port for device managment.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Once it added we can see the Array

 

 

 

 

 

Right click,  select Manage array to configure the device

 

 

 

 

 

 

 

 

 

 

 

Dash board of the device. In Setup tab you can configure password, iSCSI port ip address, Management port ip address etc

 

 

 

 

 

 

 

 

 

 

 

 

Assign ip address to iSCSI ports

Setup–>Configure iSCSI host ports

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

As per your requirement from this window you can configure ip address to all iSCSI ports ( from drop down window)

Now the MD3200i is ready. In coming artilce we will see how to create a Disk Group, Virtual Disk and LUN

Go to SCCM server -> RUN  -> dcomcnfg ->Component Services – >Right Click on My computer –>properties ->COM Security
