What is a vulnerability assessment?

A vulnerability assessment is a process of identifying, quantifying and prioritising vulnerabilities in a system, network or application. It involves evaluating the security of a system by searching and identifying weaknesses that could be exploited by cybercriminals.

Vulnerability assessment tools play an important role in this process by automatically scanning and identifying threats, providing IT teams with essential information to prioritise vulnerabilities based on risk. As such it is an essential part of any effective security programme and helps organisations identify and address security risks that require attention.

To better understand the importance of it, let’s look in more detail at security vulnerabilities that can put organisations at significant risks.

The most popular ones include weak passwords, unpatched software, social engineering, SQL injections, cross-site scripting (XSS), network security attacks or misconfigured servers. Vulnerability databases are vital in this context, as they help security analysts and teams identify and evaluate these weaknesses, supporting effective remediation strategies.

What’s important, those and other vulnerabilities can exist in any areas of an organisations’ IT infrastructure and must be addressed to ensure a strong security posture.

Vulnerability assessments and penetration testing (VAPT)

When talking about vulnerability assessment it is important to mention also VAPT – Vulnerability Assessment and Penetration Testing.

It’s a type of security testing used to identify vulnerabilities in computer systems, network and application, composed of two processes: vulnerability assessment and a penetration testing.

The latter one involves attempting to exploit vulnerabilities to gain access to sensitive information, system or networks, by simulating a hacker’s attack. This process is a form of vulnerability testing that evaluates security weaknesses across various systems, networks, and applications.

VAPT is an important process for organisations to ensure the security of their systems and networks, and to prevent data breaches or other security incidents.

The role of vulnerability assessments in protecting your IT infrastructure

Vulnerability assessments play a huge role in protecting IT infrastructure by serving as a proactive measure to identify, quantify, and prioritise potential security weaknesses before they can be exploited by malicious actors.

These assessments are an essential component of a comprehensive cybersecurity strategy, providing organisations with valuable insights into their security posture and guiding their efforts to strengthen their defenses.

At its core, the role of vulnerability assessments is to provide a systematic evaluation of an organisation’s IT systems, networks, and applications. By regularly conducting these assessments, comapnies can maintain an up-to-date understanding of their security landscape, which is particularly important given the rapidly evolving nature of cyber threats.

One of the primary functions of security procedures is to uncover potential entry points for attackers. This includes identifying outdated software, misconfigurations, weak passwords, and other security flaws that could be exploited.

By pinpointing these vulnerabilities, professionalists can take targeted action to address them, effectively closing off potential attack vectors before they can be used against them. Regular security audits help in identifying and closing these gaps, thereby enhancing overall system security and protect sensitive data.

Furthermore, addressing vulnerabilities help prioritise security efforts. By assessing the severity and potential impact of each identified vulnerability, organisations can focus their attention and resources on the most critical issues first, ensuring they get the best return on their security investments.

In the broader context of IT infrastructure protection, vulnerability assessments form part of a defense-in-depth strategy. They complement other security measures such as firewalls, intrusion detection systems, and security policies by providing an additional layer of protection.

In conclusion, vulnerability assessments are a fundamental tool in protecting IT infrastructure. They provide companies with the knowledge and insights needed to proactively address security weaknesses, meet compliance requirements, and continually improve their overall security posture.

Types of vulnerability assessments

There are many types of vulnerability assessments, and some of them include:

• network vulnerability assessment that focuses on identifying potential security risks in a network infrastructure,
• web application vulnerability assessment that involves identifying potential security risks in web applications,
• desktop vulnerability assessment that identifies potential security risks within desktop applications,
• mobile app vulnerability assessment that aims at identifying potential security risks within mobile apps.

8 steps of vulnerability assessment process

A vulnerability assessment typically consists of the following steps:

1. scoping, meaning defining the scope and objectives of such an assessment,
2. reconnaissance, involving gathering information about the system or network,
3. vulnerability scanning, used to identify potential security weaknesses in the system. Automated tools enable comprehensive scanning of the IT environment, identifying vulnerabilities across various applications and systems,
4. vulnerability assessment – a process when newly discovered vulnerabilities are analysed to determine their potential impact,
5. prioritisation, meaning grouping vulnerabilities depending on their severity, their potential impact and the likelihood of them being exploited,
6. reporting, which summarises all the findings and includes recommendations for remediation,
7. remediation, meaning actions that need to be taken to remediate identified vulnerabilities,
8. follow up, meaning conducting regular vulnerability assessments to ensure the system is safe long-term.

How much does a professional vulnerability assessment cost?

The cost of a professional vulnerability assessment can vary significantly depending on several factors, making it challenging to provide a one-size-fits-all price. Generally, small businesses with simple networks might expect to pay anywhere from $2,000 to $10,000 for a basic assessment.

Medium-sized organisations or those with more complex networks could see costs ranging from $10,000 to $30,000, while large enterprises with highly complex infrastructures might face expenses of $30,000 to $100,000 or more.

Several factors influence these costs, including:

• the size of the network,
• the number of IP addresses to be scanned,
• the types of systems and applications in use,
• the depth of the assessment required,
• the frequency of assessments (ongoing or regular assessments potentially offering better value than one-time evaluations),
• geographic location and local market rates can also impact pricing.

It’s worth noting that while these costs may seem substantial, they should be weighed against the potential financial impact of a security breach, which can be far more significant.

Some organisations opt for subscription-based models or invest in automated vulnerability scanning tools to manage costs while maintaining regular security checks. Others might choose to develop in-house capabilities, which can be cost-effective in the long run but requires investment in skilled personnel and tools.

Tools and techniques for identifying security weaknesses in your system

There are numerous tools and techniques used for identifying security gaps in IT systems, ranging from automated software solutions to manual testing methods.

Automated vulnerability scanners are among the most commonly used tools. These include popular options like Nessus, OpenVAS, and Qualys. These scanners systematically probe networks and systems for known vulnerabilities, misconfigurations, and outdated software versions. They can quickly identify a wide range of potential security issues across large networks.

Network mapping tools like Nmap are essential for discovering and enumerating devices on a network. They help security professionals understand the network topology and identify potential entry points for attackers. Similarly, port scanners are used to determine which ports are open on network devices, providing insight into potential vulnerabilities.

Web application scanners, such as OWASP ZAP and Burp Suite, are specifically designed to identify vulnerabilities in web applications.

For more in-depth analysis, penetration testing tools like Metasploit and Kali Linux provide comprehensive suites of tools for simulating real-world attacks. These allow security professionals to attempt to exploit vulnerabilities in a controlled manner, providing valuable insights into system weaknesses.

Vulnerability databases are also crucial in this context, as they help security team identify and evaluate security gaps during vulnerability testing and assessments.

Threat modeling is a proactive technique used to identify potential threats in a system’s design before it’s implemented. This involves analysing the system architecture, data flows, and potential attack vectors to identify and address security weaknesses early in the development process.

Regular and comprehensive use of these tools and techniques, coupled with a robust vulnerability management process, is key to maintaining strong IT security. The specific methods used will depend on the nature of the systems being assessed, the organisation’s risk profile, and the available resources.

When should I perform a vulnerability analysis?

Performing a vulnerability assessment is an essential step in maintaining the security of every organisation’s IT infrastructure. Consider performing it in the following cases:

• regularly, as a part of a scheduled assessment to ensure all vulnerabilities are found and addressed on time,
• before going live with a new application or when delivering new functionality; VAPT/VA should be included into every delivery process and pentest activities should be done regularly during every development process,
• after major changes to your organisation’s infrastructure, such as an installation or upgrading of a new software or changes in the data that you store,
• before implementing new systems, to identify potential weaknesses and to make sure you’ve got the right security level,
• after every security breach, to determine how it happened and check for other vulnerabilities that could be exploited,
• when needed for compliance requirements.

Need a vulnerability assessment report?

Regular vulnerability assessment can help organisations proactively address security risks before they get exploited by hackers. Bugs and vulnerabilities found during development process are less costly than those that needs to be fixed on production or when compared to cost of data breach.

What’s more, according to the new NIS2 directive – the Network and Information Security Directive 2 agreed by the European Council and European Parliament, which places a number of cybersecurity requirements on operators of essential services and relevant digital service providers – penetration testing and VA will soon be an obligatory compliance requirement for all companies under NIS2.0 regulations.
