Full Port Scan using Nessus :-


=> Follow below configuration on your Nessus while doing FULL Port Scan :-

There are two GUI which nessus supports one is html and secound is flash you can use either of them as per your convenience

=> FLASH View 
https://127.0.0.1:8834/flash.html#/

=> HTML View 
https://127.0.0.1:8834/html5.html#/

I will be showing you full port scan by taking FLASH view .

1) In Nessus Go to Policies and click on Add


2) General Setting :-

This step is critical step as you are doing full port scan setting here only
Name : Name of your scan
Visibility : Set it Private (you can set according to client requirement)
Under Port Scanner : Make sure Ping Host and TCP Scan should be unchecked
Under Port Scan Options : Give port Scan range 1-65535



3) Go to Credentials :-
Just skip this step as it is



4) Got to Plugins:-

Under Plugins make sure you disable Denail of Service. 

Note: If client want to test their environment for DOS attack then you need to take permission from respective client then after you can perform this activity.
But i strongly recommend to disable this field while doing full port sacn.



5) Go to Preferences :

Just skip this step as it is and click on Submit button.

Note: While scanning any particular server OR any machine which is password set that time we use this feature where we specifically ask client to put the credentials of machine which we are scanning generally for configuration audit we use this feature






Now at this moment your Full port scan policy is configured .

Lets see how to scan ip address.

Step 1:-  Click on Scans



Step 2 : Under Scans

Give the name , type of Scan which you are performing and policy which you just created


i.e
Name: Full port Scan

Type : There are  3 type under this, As we are doing full port scan so we will select Run Now.
           you can select Scheduled or Template as required by you .
       

Policy : Select the policy which we just created



Step 3: Scanning Ip address

Put the IP address as shown below and then click on Launch Scan.



HAPPY SCANNING ..


Few TIPS and NOTES need to remember :- 

1) TYPE OF IP ADDRESS

Below is few notes which you need to know before scanning ip address

Types of IP address :

Internal Scan :- you are scanning private ip address of the organisation
                       Private ip address include :  10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16

External Scan:- you are scanning public ip address of the organization

Public IP address vs Private IP address  


2) WHERE TO INSTALL NESSUS

I Strongly recommend you to install Nessus on VM machine loaded with Kali linux or backtrack  

Reason 1 : If you are using Home feed version you can only scan 16 IP 
Reason 2 : For scanning more than 16 IP either you need to uninstall nessus again or you require another mail id to generate new registration code 

Now to solve above issue you can refer my blog how we use home feed version of nessus and scan more than 16 IP :) 

How To Fix Error Message : In Order To Configure TCP/IP , You Must Install And Enable Network Adapter Error In Windows

22 Comments

This article applies to a different version of Windows than the one you are using.

SYMPTOMS:-
When you try to open the TCP/IP properties of your network adapter, you may receive the following error message:
Microsoft TCP/IP
In order to configure TCP/IP, you must install and enable a network adapter card.

CAUSE:-
This behavior can occur if your network adapter has been changed to another model of network adapter without first being properly uninstalled by using the Add/Remove Hardware tool in Control Panel.
OR
Often when device drivers are updated for network interface card, the mismatch between previous model of network adapter and newer one (or the newer driver) can cause a weird error which pops up when trying to access TCP/IP properties and looks something like this :



But there is a very simple fix for this and works on all versions of Windows. To remove this error.
I will show you step by step process here  :

Step 1: Right click on your desktop computer icon and go to manage


Step 2: Now Computer management dialog box will open, under that click on 
            Device manager ==>Network adapters


Step 3: Now drill down to the specific network adapter and select “Uninstall”.





Now click on OK so it will be uninstalled

Step 4:  After it’s removed, now click on  Actions ==> Scan for hardware changes.




Step 5: Now to check whether the error prompt goes or not go to start ==> Run ==> ncpa.cpl and press enter


Now you can see network connection under that right click on Ethernet (or your wirless connection where issue persisting ) and then click on Internet Protocol version 4 



Step 6: The network adapter will once again show up in installed devices list.

Now try accessing the TCP/IP properties for that adapter, the error will no longer pop-up and the IP settings can be changed as needed.

5 C’s to Run An Effective Business

Add Comment



Success has never come to anyone. Leaders went and created it for themselves. Most never
had someone to carefully guide them, or offer mentorship, which is why it’s so important
to learn from their previous choices.
If you want to be one step closer to obtaining that success, here are 5 C’s I’ve learned
to pickup over my course of doing business, and learning from others.

==> Clear 



When you’re leading a team, you expect your team to make proper decisions. However, you
still must be clear on what they need to accomplish. If you’re clear to them about what
needs to be done, and they have the approval from you to make decisions, your product will
turn out a win.

==> Concise 




We’ve all heard the acronym, KISS (Keep It Simple Stupid). The more complicated you try to
make it, the more your customers are going to want to shy away, and the longer your team
will take to understand and produce.

==> Confidence 




Confidence triumphs everything. Whether it’s walking into a meeting to pitch, giving a
demo to a customer, or being out and about in the city, confidence will always put the
icing on the cake. If you have confidence, you will know there is nothing in the world
that can stop you. Confidence allows you to exude being limitless.

==> Courteous 




No matter what you’re doing, it’s important to be courteous to others. There’s no excuse
for disrespect, ever.

==> Complete Understanding 




Don’t just look at one task, or one job. Look at the whole picture. How are you going to
benefit 3 years down the road? How will the rest of the team benefit with this success?

As Churchill once said, “Success is not final, failure is not fatal: it is the courage to
continue that counts.”

We often encounter human verification (CAPTCHA) inside registration pages, comment sections, or any other kinds of submission forms. But, dealing with CAPTCHAs every time we try to fill out any forms, is a frustrating job. Sometimes, we do not recognize some letters in a certain CAPTCHA.

Rumola, a new browser addon, will be helpful in this situation which lets you bypass captcha verification and automatically fills the captcha codes in websites.

How to Bypass Captcha verification using Rumola

Open an account at Rumola. (you’ll get 10 free trials at registration)

Install the addon required for your browser.

For Firefox : https://addons.mozilla.org/en-US/firefox/addon/rumola-bypass-captcha/

After installing the addon, restart your browser if required and once the plugin is activated, it will automatically start filling captchas for you.

Demo time :
