What is Penetration Testing?
It’s referred to as a Pen test. Penetration Testing is used to evaluate the security of an IT infrastructure. It is a process to identify security vulnerability within an application by evaluating a system or network with the help of different malicious techniques. Vulnerable areas of system or application identified through a process of an authorized simulated attack on the system. The primary purpose of executing this type of testing on a system is to track the data from outsiders like hackers that make unauthorized access to a system.
Once a vulnerability identified into a system, then that weak area of the system used by the hacker to gain access to a system or to get sensitive information from a system. The one who executes a penetration testing on a system, but into the legal way referred to as an ethical hacker. These types of hackers hired by an organization to find out vulnerable areas of an application, later on, these vulnerable areas cannot find out by the unauthorized hackers to damage or destroy a system.
How does Penetration Testing Work?
There are different types of Penetration tests –
Social Engineering Test
It is a type of testing, executed to make a person reveal sensitive information such as a password or it can be business critical data, etc. These type of tests made with the help of a phone or the Internet to target specific help desks, employees and processes. In this human errors are the primary causes of security vulnerability. In these security standards and policies followed by all the staff members to avoid any penetration attack.
For example – Sensitive information should not be shared in the email or phone communication. Security audits conducted to identify incorrect flaws.
Web Application Test
It is a type of testing to check the vulnerability of web applications and software programs positioned in a specific environment.
Physical Penetration Test
- It is a strong security method.
- It is used to protect sensitive data.
- It is normally used in military and government facilities.
- In such type of organizations network devices and access points tested for possibilities of security flaws.
- It is not relative to software testing.
Network Service Test
- It is a type of testing through which loopholes and the opening of the network identifier.
- It’s all about to identify an entry point for a system or application and also to check what kind of vulnerabilities be there.
- It is done locally or remotely.
Client Side Test
This type of testing is all about to search and find out a vulnerability in client-side software systems.
Remote Dial-Up war Dial
It finds out modems in an environment and to login systems connected to this modem by using a technique of a Password Guessing and Brute Forcing.
Wireless Security Test
It is a type of testing that finds out open, unauthorized and less secured hotspot or Wi-fi networks along with this also makes the connection with these unsecured networks such as hotspot or wifi to make testing for the application.
As penetration testing categorizes into seven types that are also mentioned above, these above seven mentioned techniques can also be summarized into three, which are explained as following three –
Black Box Penetration Testing
It is a type of testing approach, tester accesses a target system, network, and processes without having any internal knowledge of a system. It has an internal level of details such as URL or company name to penetrate a target environment. No code examined for this type of testing.
White Box Penetration Testing
To do this type of testing, complete details about a target environment needed such as systems, network, OS, Addresses, source code, schema etc. It examines code as well as find out a design and development of relative issues. This type of testing is a simulation of an internal security attack.
Gray Box Penetration Testing
It is a type of testing with limited details about the environment. It’s rendered as external security attack.
Penetration Testing Methods
There are five types of penetration testing methods that are explained –
External penetration tests target assets of application that are visible on an Internet such as a web application itself, company website, email address and Domain name servers(DNS).
The main goal of this type of application is to gain access and extract valuable data from an application on which testing is going to happen.
In this type of Internet test, a tester with access to an application behind its firewall. Conman basic scenario covered under this such as an employee whose basic credentials stolen due to a Phishing attack. The phishing attack is a type of attack to steal user’s information such as credentials etc.
It is a type of testing in which tester is provided only with the name of the organization at which testing performed. It is a type of testing that provides a real look of testing. It provides a view of what will occur when actual testing takes place. This gives security personnel a Real-Time observation that how application executed in Real-Time.
Double Blind Testing
It is a type of testing, in which security person does not have knowledge for a simulated attack that is going to occur. It helps to provide a Real-Time view and shows what will happen if attack going to happen in Real-Time situation.
It is a type of testing in which hacker and personal security work together. It provides a security team with Real-Time feedback from authorized hacker’s point of view.
Penetration Testing Techniques
There are three ways or techniques to do penetration testing. These are mentioned as following –
- The manual way of penetration testing.
- An automated way of penetration testing.
- Combination of Manual and Automation of Penetration Testing.
How to Adopt Penetration Testing?
Planning and reconnaissance
It is the first phase of Penetration Testing. The first aim here is to define the scope and goal of the test. It also includes systems to be addressed and testing methods to be used to test that system.
Understand how a target application responds to the different type of intrusion attempts. It can be done typically by following ways. For this, there is a need to go through following two types of analysis –
It provides an estimate that how the application behaves in a running state. In this type of analysis, all code scanned in a single pass. Sometimes tool used to do Static Analysis.
It is the type of analysis to inspect application code in a running state. It is a more efficient way of scanning as it provides a Real-Time view into an application’s performance.
Testers then try and exploit these vulnerabilities, typically by escalating privileges, stealing data, intercepting traffic, etc., to understand the damage they can cause. It is a stage that uses web application attacks such as cross-site scripting, SQL injection, and backdoors to uncover the target system’s vulnerabilities. Testers then try to exploit vulnerabilities through breaking privileges issue, stealing data and intercepting traffic, etc. This helps to understand what type of damage will occur if the attack will occur in actual.
The main aim of this stage is to check that if a vulnerability used to achieve a persistent presence in an exploited system. This type of attack access for a large time in an exploited system to steal important information from a system.
Analysis and WAF configuration
The analysis contains the information explained as follows –
- Specific vulnerabilities that were exploited.
- Sensitive type of data accessed from an application.
- Amount of time at which pen tester able to remain in a system undetected.
Benefits of Penetration Testing
- Detection and Arrangement of Security Threats.
- Identifies high-risk vulnerabilities.
- Efficiently manages security weaknesses.
- Downtime cost reduction.
- Regulatory Compliance.
- Follows industry standards.
- Includes Third-Party Platforms.
- Security Assessments.
- Enhances Customer Loyalty.
- Detects hidden vulnerabilities.
- Session Management.
- Reveals authentication flaws.
Why Penetration Testing Matters?
What is WannaCry ransomware
WannaCry ransomware is an attack spread in May 2017. It had locked more than 2 lakh computers around the whole world and demanded payments in the form of a Bitcoin Cryptocurrency. It was an attack that has affected many big organizations around a globe. With more and more Cyber attacks happening these days, it’s becoming unavoidable to avoid a penetration testing attack
As WannaCry ransomware attack affected many computers in May 2017. With an increase in numbers of massive and dangerous attacks, it becomes unavoidable to do Penetration Testing. It is required to execute a penetration testing for the security of system against security breaches or different security parameters depending upon the requirement.
- Data relative to finance and also critical data transferred securely, it transfers data between different systems and different networks.
- Nowadays, many clients ask for Penetration testing as part of a software release cycle because of security of data.
- It also helps to discover the loopholes of the system.
- It is important to get aware of business risks if an attack has to happen.
- Implementing an effective security strategy in an organization is important.
Best Practises of Penetration Testing
- To do Penetration Testing, it is required that the system should be deployed.
- Perform testing on Real-Time.
- Check the behavior of the application by applying attacks on the application in Real Time.
Penetration Testing Tools
A good tool possess following features –
- Easy to deploy, configure and use.
- Scan system easily.
- Categorize vulnerabilities on the basis of severity that needs an immediate fix.
- Automate the process for verification of vulnerabilities.
- Generate vulnerability reports and logs in a detailed format.
Tools to execute Penetration Testing named as follows –
Concluding Penetration Testing
In conclusion, Penetration Testing executed when the application is working properly. Then a different type of testing methods applied on the application, depending upon the requirement of the application. It finds vulnerable areas of application in advance by an authorized hacker so that, it cannot be hacked by any unethical hacker.
