Vulnerability Assessment evaluates your system for any known vulnerabilities and prioritizes them for remediation purposes. It is used to check the susceptibility level of your network to different types of vulnerabilities.
Need for Vulnerability Assessment
Vulnerability assessment is critical for every organization to identify risks and vulnerabilities in the network, system, hardware, application, etc. It also helps organizations,
Vulnerability assessment: Categories
Based on the assessment infrastructure, Vulnerability assessment can be classified into three types.
- External Scans: External scans looks for loopholes or vulnerabilities in the IT ecosystem that are accessible to external users like ports, websites, network firewalls, etc.
- Internal Scans: Internal scans looks for vulnerabilities in the internal network of an organization. This type of scan is done from the perspective of an insider who has access to the systems.
- Environmental Scans: Environmental scans concentrate on a specified operational technology of an enterprise like IoT, Cloud services, websites, mobile devices, etc.
Vulnerability Assessment: Methods
- Host-based Scanning: This method of scanning identifies the vulnerabilities and issues in the host by running scans on the workstations, servers and network hosts.
- Network-based Scanning: This is the process of scanning the wired and wireless networks to recognize and remediate security vulnerabilities. It detects the open ports, then identifies the active devices and unknown services running on these ports.
- Database Scanning: Database scanning helps to identify the security gaps in the databases to help prevent data breaches caused by SQL Injections – where the hacker can inject SQL statements into the database and steal information.
Vulnerability Assessment: Phases
The different phases involved in the Vulnerability Assessment are explained below.
- Vulnerability Identification: The first phase in vulnerability assessment is to identify and draft the list of vulnerabilities. The security analysts check the security posture of the organization and identify the security weaknesses.
- Vulnerability Analysis: This phase deals with the identification of the root cause of vulnerabilities found in the first phase. Each vulnerability is analyzed and the source or system components responsible for the vulnerability is identified for easy remediation purpose.
- Risk Assessment: The purpose of this phase is to prioritize each vulnerability based on factors like severity of the probable attack, business functions that are under risk, potential damage caused, systems that get affected, etc.
- Remediation: The objective of this last phase is to close the security gaps or find solutions to each vulnerability. The security analysts suggest new procedures or policies for implementation for the effective mitigation of identified vulnerabilities.
Penetration testing is a simulated attack; that helps to identify the type of resources exposed to the outer world, the network security risk involved in it, the possible types of attacks and the prevention of these attacks.
Need for Penetration Testing
As a result of the growing business demands, the IT infrastructure of every organization is becoming more complex day by day. The internal networks are given access over the internet to the legitimate users along with the user credentials and the privilege level; outside the firewall, which increases the surface of the attack. Hence it is critical to do a network security assessment of these infrastructures regularly to detect security threats.
Penetration Testing: Methods
- Black Box Penetration Testing: This test is carried out with zero knowledge about the network. The tester will not have access to any of the client’s applications, network and internal information.
- White Box Penetration Testing: This test is called complete knowledge testing and is used to check the robustness of the network in a specific environment, where the security information cannot
- Gray Box Penetration Testing: This test is performed with limited or partial knowledge of the network’s security information.
Penetration Testing: Types
- External Penetration Test: This Penetration test simulates a hacker’s attempt to enter and exploit the vulnerabilities in real-time within the network.
- Internal Penetration Test: This penetration test identifies the risks that arise from within the network, assuming that the attacker already has access.
- Segmentation Testing: This penetration test ensures that the communication between the less-secure network and high-secure network is restricted.
- Mobile Penetration Testing: The main aim of this testing is to find how the app interacts with the server-side systems and find security flaws in the application.
- Web Application Penetration Testing: This type of penetration testing is done to evaluate thearchitecture and configuration of web applications in order to identify security vulnerabilities that might lead to unauthorized access and data breaches.
- Wi-Fi Penetration Testing: Wi-Fi Penetration Testing is an authorized hacking attempt, where the tester hacks the wireless system to identify the vulnerabilities in the security controls.
- Thick Client Penetration Testing: Thick client penetration testing tries to exploit the vulnerabilities associated with the application like insecure storage, denial of service, reverse engineering, improper session management, etc.
- API Testing: The aim of API Penetration Testing is to maximize the API benefits by identifying the risks and vulnerabilities imposed by them.

Penetration Testing: Phases
The different phases involved in Penetration Testing are given below.
- Network Discovery: In this phase, network mapping of the internal or publicly exposed IP addresses will be done to identify information such as Active Hosts, Active Services, Insecure Services, Fingerprinting the Operating System and Services, etc.
- Public Information Assessment: In this phase, the testers will identify the public information about the client in systems that are under the scope of services. The results of this assessment will be useful for identifying the potential vulnerabilities related to the systems.
- Vulnerability Scanning: In this phase, automated vulnerability scanners will be used to detect and verify the known vulnerabilities by utilizing automated vulnerability scanners.
- Attack, Exploitation and Privilege Escalation: Based on the outcome of vulnerability assessment, the analysts perform threat modeling where each vulnerability is studied carefully and plan attacks that will exploit all exploitable vulnerabilities, simulating the potential impact of an attack.
- Remedial Action Identification: In this phase, security analysts prepare the remedial actions for the threats and vulnerabilities discovered in the previous phases.
- Reporting: Technical findings will be written up into a formal report consisting of an Executive summary highlighting business risks, and a detailed technical report containing the description of vulnerabilities found, their severity, ranking and recommendation for remediation.
Summing up, we can say that Vulnerability Assessment and Penetration Testing Services helps your organization,
- Prepare for the undetected or unseen breaches
- Strengthen the cybersecurity strategies
- Reduce remediation costs and downtime
- Ensure compliance with security standards
