What is Vulnerability Assessment in Cyber Security?
Cyber security is the backbone of digital businesses because it helps enterprises meet compliance and ensure data security by protecting all ends of a business from malicious attacks.
Enterprise devices might contain sensitive data like protected health information, personally identifiable information, government or general public information, and official documents. It is necessary to protect the official data from vulnerabilities like DDOS attacks and ransomware.
Cyber security vulnerability assessments are performed to ensure the safety of digital devices operational in businesses like smart mobiles, computers, servers, networks, and other gadgets. Let's discuss some essential vulnerability assessments and their significance for businesses to ensure data security.
1 What is Vulnerability Assessment in Cyber Security?
Vulnerability assessment in cyber security is a systematic approach to identifying and analysising the extent levels of software vulnerabilities. It helps developers and security experts diagnose vulnerabilities using advanced assessment tools to test software from different perspectives and proactively take precautionary measures to avoid damage.
Vulnerability assessment can be done on various layers of technology to prevent malicious actors from compromising the security of enterprises. Organizations can timely identify weaknesses in their software and safeguard it to prevent data access by unauthorized users.
Vulnerability is a gap or weakness in security measures that provide space for hackers to attack a system. Common vulnerabilities include cross-site scripting, SQL injections, ransomware, and DDoS attacks.
The primary goal of vulnerability assessment is to identify the flaws in the code and design of an application, document it in detail for the developers' clear understanding, and provide guidelines to assist developers with optimized ways to remove vulnerabilities. It is vital for business entities to smoothly manage business operations without privacy exploitation by some unknown sources. It helps them reduce risks, ensure compliance, develop proactive security measures, and continuously improve business structure within secure boundaries.
2 Three Main Types of Vulnerability Assessments
Application-based vulnerability assessment
Vulnerability assessments based on applications aim to inspect software apps for potential security flaws. It comprises a detailed analysis of code, configuration settings, and overall architecture to determine vulnerabilities such as SQL injection or cross-site scripting. It is essential for organizations that typically rely on custom-developed software, as it ensures the security and safety of applications by preventing attacks at the application layer.
Network-based vulnerability assessment
These vulnerability assessments focus on the overall security of a network's infrastructure, such as routers, firewalls, and switches. Network-based assessments utilize tools to scan IP addresses, open ports, and network services to detect vulnerabilities such as unpatched software or weak authentication processes. This type of assessment offers information about the organization's network security to strengthen its defenses against external and internal threats.
Host-based vulnerability assessment
Host-based vulnerability assessments primarily focus on individual computer systems or hosts to investigate operating systems, installed software, and configurations. It ensures the security of each host by utilizing automated tools to scan for known vulnerabilities and misconfigurations, preventing attacks that attack a given operating system or installed software. Host-based assessments help admins ensure the security of individual systems in an organization's IT environment.
3 The Processes to Implement Vulnerability Assessment
- Step 1.Initial Preparation
- The first phase of cyber vulnerability assessment outlines the scope and primary objectives of testing. The process includes identifying and analyzing assets and the potential risks for these assets if exploited by vulnerabilities.
Security teams also check the data-sharing mediums to ensure the safe transfer of sensitive information. Moreover, they verify access controls and basic security requirements. To better understand potential attacks, security teams proactively record the baseline information about services, processes, open ports, operating systems, and software deployed on assets. This information helps developers to implement robust security measures.Note : SAST is a helpful tool for identifying vulnerabilities at the early stages of development to prevent long-lasting damage. You can use Nmap for network mapping and OWASP ZAP for open-source testing.
- Step 2.VA (Vulnerability Assessment) Testing
- At this phase of assessment, the security team conducts advanced and automated scans on required devices. This phase also uses manual tools to confirm and diagnose vulnerabilities manually. They use one or more vulnerability databases, vendor security advisories, and threat intelligence feeds to increase effectiveness. The period for each test may vary, depending on the type of scan and the size of target applications.
- Step 3.Prioritize Vulnerabilities to manage security
- After successfully testing vulnerabilities, it is necessary to prioritize risks depending on the extent of damages they can cause to a business by data breaches. Categorize the vulnerabilities based on the severity score achieved by the VA. Analyze the risks they can impose on the sensitive data and the overall damages to the businesses if these vulnerabilities are exploited. You can also manage the vulnerabilities depending on the period they have been in the application because vulnerabilities increase damages as time passes. Prioritize them based on the availability of patches and the workforce or tools required.
- Step 4.Create VA Report
- After carefully categorizing the vulnerabilities, security teams need to compile them in a comprehensive report summarizing the vulnerabilities and their possible immediate solutions to remediate them. This report must include high-risk vulnerabilities and the time when they were discovered, the damages caused by each vulnerability, and the solutions for developers to resolve them as early as possible. POC (proof of concept) demonstration is also a suitable way to help developers analyze how high-risk vulnerabilities can be exploited.
- Step 5.Regularize VA
- Security vulnerabilities are dynamic, so developers and businesses can face issues anytime while using applications. So, continuous vulnerability assessment is integral to ensure data security throughout. Security teams automate vulnerability assessment as a vital part of the CI/CD pipeline in software development to mitigate security risks during the SDLC. Although it is an effective strategy, there still needs to be a continuous vulnerability assessment of applications, especially after app updates, so if any new vulnerability arises, it could be identified at early stages.
4 Why Is Vulnerability Assessment Important? And When You Need
Businesses hire security teams or purchase services from third parties, ensuring application security for safe usage. These security professionals perform cyber security threat assessment to verify that the company's digital devices and applications are secure to deploy and conduct operations.
It is essential for businesses because many cybercriminals keep trying to access the company's sensitive information and files. They can easily damage and share files or break down the system after getting unauthorized access to the device or network.
Businesses can identify weaknesses in the system by practicing vulnerability assessments at early stages to avoid massive damages. You can remove a system from the network if it is found suspicious and reconnect once the vulnerabilities are resolved. Similarly, if any app is found containing malicious content, security teams can instantly remove the app to prevent hackers from hijacking the whole system through it.
Enterprises also perform VA to ensure their current security parameters adequately cope with malicious attacks. They test their existing security measures to see how well they perform and what weaknesses they have. All of this can be done using vulnerability assessment.
Every industry contains security requirements and criteria enforced by regulatory agencies for officials to work in a specific domain. So, vulnerability assessment requirements and security measures also vary with industry needs. Regular VA helps businesses remain compliant with regulations and ensure data security.
Some widely followed compliance standards include the General Data Protection Regulations (GDPRs), the Health Insurance Portability and Accountability Act (HIPAA), and PCI DSS. It also helps them safeguard customer's data to avoid trust issues. Comprehensive reports generated after vulnerability assessment allow developers and businesses to ensure data security and prevent malicious attacks by outsiders.
