Information Security Controls

Information Security controls is mechanism or a set of rules to to decrease the risk in terms of vulnerability , internal and external threads etc. Information security also covered the other aspects of an organisation like Computer Security , Physical Security , Network Security , Business Continue Planning , Disaster Recvery Planning, Counter Measures With Existing Or Future Attacks.

These controls facilities an organisation to keep his Information Confidentiol from external or internal attacks, Its maintain and help organisation to keep running their system after any attacks.

Its also proview you an view that how much your Information secure.



Here are some important thing which you should be covered under Information Security Controls.

  • This rule comes under the physical security , In this set each and every person should be pass into the organisation by well managed physical security which should be monitor properly to identify the unknown Intruder.

  • Every information which generated or produce in an Organisation should be properly backup time to time to prevent data loss due to hacking attempt and system failure, Its also recommended to create an extreme back and restore system which should run and managed properly.

  • Incident Response should be there to perform an immediate reply for any incident which can be anything like , Fire attack , physical attacker or any technical hacking attack.

  • Keep you employee Train And Educated about Any incident its also covered in Information Security Controls , If your employee is well trained about these types of situation then there will be less chance of any loss in an organisation.

  • Log monitoring Must be in organisation to identify the Inside and outsider attack before the incident happened , Many organisation use Log Monitoring for their web application and internal system , Incoming and outgoing traffic.


Information security controls are mainly Devided in 7 Categories

Information Security Controls

Information Security Controls


1. Network Security

2.Access Control

3. Security Management

4.Physical Security

5.Business Continuity & DR Planning

6.Operations Security

7.Application/System Security


1. Network Security Controls

Network Security Controls if the first or the important part for an organisation because this part start from bottom line or you can say that this is the heart of any Company . Network Security Covers his internal devices like routers , Switcher and other devices which is very important for an organisation to continue his work.

Setting Up firewall and UTM are recommended for every organisation to keep controls on their Network Environment .


2. Access Controls

Access controls Covers the right or privilege for each and every user which is under an organisation and internal employees , Access controls is comes as Authorization.This is very important that every user his limited user privilege and right to continue his work , Like an employee for any organisation should not able to access administrator level access things action Like changing some one password , access to internal resources , Etc.

 3. Security Management

Security management is the classification of an organization assets inventory which should be followed by proper guidelines , rules set and documentation.Many organisation create Security Policies which should followed by his employee. Like no employee can bring any storage devices in office primasius which decrease the risk of insider data theft.

4. Physical Security

Physical Security its also an important factor for an organisation to identify an unknown intruder or attacker, decrease the risk of business loss like fire attack , earth quake or any natural or unnatural attack.

Many things are comes under the Physical Security Like , CCTV Cameras, Security Guards , Fire Preventions Systems

Entry Gates authentication such like Finger Print Scanner or Eye Detection Mechanism.



5. Business Continuity & DR Planning

Business Continuity & DR Planning allow an organisation to keep running his business regularly if he is/was under attack , Data loss or system failure.

This control managed the whole data of an organisation which automatically back up time by time , to restore  in case of data loss or any hacking attack.



6. Operations Security

OPSEC ( Operation Security ) Covers unwanted or unintended risk which can be performed against us,OPSEC maintain these all things to take care that is there any information can be used against us or not.



7.Application/System Security

Application/System Security is an major control for an organisation to maintain his on-line identify safe and confidential. This controls covers that we should maintain our Application/System Security by different technologies like Firewall , IPS , SIEM and Other Log Monitoring Systems.

This will help an organisation to keep them self secure before or while the attack.

Pentesting Node.js Application : Nodejs Application Security

Pentesting Node.js Application : Nodejs Application Security

Pentesting Node.js Application : Nodejs Application Security

Hello folks, Today we will see how we can do Pentesting Of NodeJS Application : Attacking NodeJS Application.

As we know that Javascript is a very common and important language and also a light wight which do our most of task very easily.

But we also know that, Great efficiency comes with great risk. Node JS is a kind of server side programming language derived from JS.

According to Wiki

Node.js is an open-source, cross-platform JavaScript run-time environment for executing JavaScript code server-side. Historically, JavaScript was used primarily for client-side scripting, in which scripts written in JavaScript are embedded in a webpage's HTML, to be run client-side by a JavaScript engine in the user's web browser. Node.js enables JavaScript to be used for server-side scripting, and runs scripts server-side to produce dynamic web page content before the page is sent to the user's web browser. Consequently, Node.js has become one of the foundational elements of the "JavaScript everywhere" paradigm,[4] allowing web application development to unify around a single programming language, rather than rely on a different language for writing server side scripts.


Today we will see some of the vulnerabilities which can be exploited in Node.JS application. We will also take a look on the source code for better understanding.

iOS Application Pentesting Part 1 : Setting Up The Attacking Environment

iOS Application Pentesting Part 1 : Setting Up The Attacking Environment

iOS Application Pentesting Part 1 : Introduction To iOS 


In this article, we will see essentials tools and environment which we required to perform penetration testing and Vulnerability assessment on iOS Applications.



JailBreaking Your Device : ;) 

First thing first, if you are very serious about iOS Application Pentesting then you should required a Jailbroken device with you.
Below we will see how we can JailBreak a iOS Device.
iOS JailBreaking have a great history, First pangu have Jailbroke the iOS then other team did the same.
Be frank to Jailbrea iOS device, First you need to check whether your Installed iOS Version is already JailBroken or not. 

Note - For this particular tutorial we will use Xcode Simulator but highly recommended you to get A Jailbreak Device if you are very serious about learning iOS Application Pentesting.

Exploiting Software Based Vulnerabilities : Attacking Network - Pentesting Network

Exploiting Software Based Vulnerabilities : Attacking Network - Pentesting Network

Exploiting Software Based Vulnerabilities : Attacking Network - Pentesting Network 


Vulnerabilities exist on a particular machine can be software and hardware based. Today we will see how we can Exploit Software Based Vulnerabilities to take over target machine.


Software based vulnerabilities are nothing, but just a coding/programming error exist in a Particular software version or series. Which can be hacked/compromise using a group of malicious code called as an "Exploit".


First we have identified a SMTP service on our target machine 192.168.131.137

SLmail smtpd 5.5.0 4433 is running in port 25

Hacking SNMP Service Part 1 - The Post Exploitation : Attacking Network - Network Pentesting




Hacking SNMP Service Part 1 - The Post Exploitation : Attacking Network - Network Pentesting

Hacking SNMP Service Part 1 - The Post Exploitation : Attacking Network - Network Pentesting


SNMP (Simple Network Management Protocol)

Simple Network Management Protocol (SNMP) is a popular protocol for network management. It is used for collecting information from, and configuring, network devices, such as servers, printers, hubs, switches, and routers on an Internet Protocol (IP) network.

With lots of usability, SNMP can be used by an attacker to compromise the services and IT infrastructure as well. which will cover later.


Now we will see how we can brute force the SNMP Services Community Strings.


But Why Crack SNMP Community Strings

The SNMP Read-Only Community String is like a user id or password. It is sent along with each SNMP Get-Request and allows (or denies) access to a router's or other device's statistics. If the community string is correct, the device responds with the requested information. If the community string is incorrect, the device simply ignores the request and does not respond.


What We Can Do By Community Strings.

Default community strings are "public" & "private" with "ro" (Read Only) & "rw" (Read & Write).
As it clear indicates, that Read only means user can only read the information & Read and Write means user can write/update the information present in SNMP.

Hacking SNMP Service Part 2 - The Post Exploitation : Attacking Network - Network Pentesting


Hacking SNMP Service Part 2 - The Post Exploitation : Attacking Network - Network Pentesting

Hacking SNMP Service Part 2 - The Post Exploitation : Attacking Network - Network Pentesting

From our previous post, We have identified the community strings Via Nmap Scan & Brute Forcing the Community String Values.

Now we will see, How can we use those Extracted Community strings for Post Exploitation.

To perform We will use various tools as mention below.

What Is MIB in SNMP

The SNMP Management Information Base (MIB) is a database containing information
usually related to network management. The database is organized like a tree, where
branches represent different organizations or network functions. The leaves of the tree
(final endpoints) correspond to specific variable values that can then be accessed, and
probed, by an external user. To read more about the MIB tree, refer to the following


For example, the following MIB values correspond to specific Microsoft Windows
SNMP parameters.
1.3.6.1.2.1.25.1.6.0        System Processes
1.3.6.1.2.1.25.4.2.1.2     Running Programs
1.3.6.1.2.1.25.4.2.1.4     Processes Path
1.3.6.1.2.1.25.2.3.1.4     Storage Units
1.3.6.1.2.1.25.6.3.1.2     Software Name
1.3.6.1.4.1.77.1.2.25      User Accounts
1.3.6.1.2.1.6.13.1.3        TCP LocalPorts

Metasploit Pivoting And Port Forwarding : Attacking Network - Pentesting Network

Metasploit Pivoting And Port Forwarding : Attacking Network - Pentesting Network


Metasploit Pivoting And Port Forwarding : Attacking Network - Pentesting Network 


Metasploit pivot technique helps an attacker to Compromise the other Machines which attacker don`t have access to.

So the scenario would be like below.

Attacker: 192.168.23.X
Attacker Can Communicate With System A: 192.168.31.X
A System Can Only Communicate With B System : 10.1.1.X
Attacker Wants To Communicate With Other Systems Using System B.
We also consider that, attacker dont have idea about the System C IP Address.


Pivoting can be achieved in below steps.


Pivoting can be perform in following steps:
  1. Compromise primary target machine (System A)
  2. Search for System network interfaces.
  3. Add route to metasploit session of System A.
  4. Run Proxy server
  5. Scan the Second target machine (System B)
  6. Port forwarding
  7. Perform Exploit

Default Credentials Vulnerability : Attacking Network - Network Pentesting



Default Credentials Vulnerability : Attacking Network - Network Pentesting


Default Credentials Vulnerability : Attacking Network - Network Pentesting


Hello reader, We have talked lots of about Web Hacking & today i decided to blog some intresting things about Attacking Network - Network Pentesting.

For your information, for demonstration purpose i am using Vyatta VM, which you can also download from http://packages.vyos.net/iso/release/1.1.7/ 

Today we will see the common vulnerability which most of admin do, by keeping default configuration or you can also say keeping default credentials.

So we have a Target machine on 192.168.131.135 & our Attacking Machine on 192.168.131.134

Lets do a Nmap Service Scan on our target machine.

nmap -sV 192.168.131.135 

Default Credentials Vulnerability : Attacking Network - Network Pentesting


So we got some information like port 22, 23, 80 & 443.
Apart from all port, 22 & 23 looks interesting for us and it might possible that credentials would be default for that service.
