Vulnerability Assessment

A vulnerability assessment is a kind of testing procedure used to detect, recognize, and assign severity ranks to the maximum number of security defects in a stipulated timeframe. A vulnerability assessment procedure employs automated and manual techniques with changeable degrees of severity with more focus on comprehensive coverage. A vulnerability assessment may target and work at different layers of technology including the host, network, and application layer assessments.

 

Vulnerability Analysis

 

 

Through this platform we are trying to educate our readers about a procedure that must be followed by IT organizations for the security of their IT infrastructure.

 

Vulnerability Assessment - Definition and Introduction

 

The more technical definition of a vulnerability assessment states that it is a systematic review of security weaknesses and threats within various components of the information system. Vulnerability assessment is aimed to evaluate and assess if the information system is prone to any known vulnerabilities, allocates severity levels to identified vulnerabilities, and thereafter, proposes remediation or mitigation based on the requirement.

 

A vulnerability assessment is a critical and obligatory component of the vulnerability administration and IT risk management lifecycles with its potential to help protect IT systems and data from unofficial access and data breaches.

 

Vulnerability assessment procedure typically employs tools like vulnerability scanners to note down threats and flaws within an enterprise's IT infrastructure that correspond to future vulnerabilities or risk exposures.

 

Software vulnerability

 

Before going into more technical details of vulnerability assessments it is important to understand the meaning of software vulnerability.

 

A software vulnerability can be defined as -

 

It is a bug in code or a defect in software design that can be harmful to the system. More technically, it is a gap in security procedures or a flaw in internal systems that when conquered results in a security breach.

 

Software Vulnerability

 

 

Vulnerability assessment can prevent the following types of threats.

 

 

Importance of Vulnerability Assessment

 

Vulnerability assessment is a mechanism that allows security engineers to apply a comprehensive, consistent, systematic and clear approach to detecting and resolving security threats and potential risks. It provides numerous benefits to an organization.

Tools Used For Vulnerability Assessment

 

A vulnerability scanning tool plays a significant role in vulnerability assessment. This tool is responsible for various types of scans, including -

 

 

While choosing the vulnerability scanning tool the following aspects are considered.

Vulnerability Assessment Framework

 

A well-defined framework for a vulnerability assessment task is composed of the following discrete steps.

 

However, security experts mainly assume that attacks happen externally, and hence, internal pen test becomes less significant from a security perspective. But these tests can be advantageous to avoid malicious employee attacks or ex-employee attacks on your web systems. It also prevents your web applications from phishing attacks, social engineering attacks, misuse of user privileges, and unlocked terminals.

 

1. Vulnerability identification or testing

 

The main aim of this step is to formulate an all-inclusive list of an application’s vulnerabilities that can potentially affect the application. Security analysts assess and monitor the security health of applications, associated servers, and other systems by scanning them with the help of automated tools, or with the help of manual tests and evaluation. Analysts also perform tests to assess vulnerability of databases, asset management systems, vendor vulnerability announcements and threat intelligence feeds to find out security weaknesses and threats.

 

2. Vulnerability analysis

The purpose of this phase is to recognize the source and core cause of the vulnerabilities noticed in the previous step. This step is intended to identify system components that caused vulnerability, and the root causes behind it. For example, many times the root causes can include old versions of used libraries, etc.

 

3. Risk assessment

The third step of this framework prioritizes all vulnerabilities where each vulnerability is assigned with severity score or rank by security analysts. They consider the following factors while assigning the severity level.

 

  • Affected system
  • Data risk
  • Affected business functions
  • Business functions at risk
  • The severity of an attack.
  • Ease of attack
  • Potential damage due to the susceptibility

 

4. Remediation

The final step of this framework is aimed to close security gaps. It is collaboratively performed by security staff, development teams, and operations teams. They together determine the most efficient way for remediation or mitigation of each security weakness.

 

Remediation

 

 

Its steps include -

 

  • Use of new security measures, procedures or tools.
  • Reflecting configuration changes as per the requirement.
  • Development and execution of a vulnerability patch.

 

For effective Vulnerability assessment, it is practiced at regular intervals and it is not assumed as a one-off activity.
