Vulnerability management is an essential component of any cybersecurity strategy. It involves an ongoing assessment, prioritization, and treatment, as well as a complete assessment of IT systems' vulnerability. This article explains vulnerability management in good detail, as well as its key processes and best practices for 2022.

Many businesses depend on the internet as a primary worldwide resource. However, connecting to the internet can expose their networks to security hazards. Cybercriminals enter networks, sneak malware into computers, steal sensitive information, and shut down their systems.

As a result of the epidemic, remote work has increased, increasing security threats even more, putting any organization at risk of a data breach or malware assault.

Cyberthreats will be the top concern for companies worldwide in 2022, according to the Allianz Risk Barometer.

According to Gartner, roughly 30% of critical infrastructure businesses will experience a security breach before 2025. The interruption will disrupt operations within the organizations.

This is why, for both large and small enterprises, proactive detection and close-up security gaps is a must. This is where vulnerability management comes in.

What is vulnerability management?

Vulnerability management is an essential component of cybersecurity strategies. It involves a proactive assessment, prioritization, and treatment, as well as a thorough investigation of vulnerability within IT systems.

A vulnerability is a condition of being open to harm or attack in any system. In this day of information technology, organizations store, share, and secure information. These necessary activities expose the systems to a wide array of dangers, including open communication ports, unsecure application setups, and exploitable holes in the system and its surroundings.

Vulnerability management assesses IT assets and compares them to a constantly updated vulnerability database to identify threats, misconfigurations, and weaknesses. Cybercriminals should avoid exploiting vulnerabilities in IT systems regularly, which might result in service interruptions and costly data breaches.

Although vulnerability management is often confused with patch management, they aren't the same thing. Vulnerability management involves a whole system of thinking about which threats need immediate attention and how to remediate them.

Key processes in the vulnerability management lifecycle

Vulnerability management is a multistep process that must be completed in order to remain viable. It often evolves in tandem with the expansion of organizations' networks. The vulnerability management process lifecycle is designed to assist organizations in recognizing threats, prioritizing assets, and preparing a report to show the threats have been addressed.

Vulnerability assessment is a critical part of vulnerability management because it assists in the identification of vulnerabilities in your network, computer, or other IT asset. It then recommends mitigation or remediation if and when necessary. Vulnerability assessment involves using vulnerability scanners, firewall logs, and penetration testing results to identify security vulnerabilities that might result in malware attacks or other malicious events.

A vulnerability assessment determines if a vulnerability in your system or network is a false positive or a true positive. It tells you how long the vulnerability has been on your system and how much impact it would have on your organization if it were exploited.

Unauthenticated and authenticated vulnerability scans are useful for identifying many vulnerabilities, such as missing patches and configuration issues. However, when identifying vulnerabilities, caution should be exercised, as other sections of your system may be affected if not properly mapped.

Once vulnerabilities have been identified, they must be prioritized so that the consequences posed can be properly neutralized. It is directly related to its ability to focus on the weaknesses that pose the greatest threat to your organization's systems. It also assists in the identification of high-value assets such as personally identifiable information (PII), customer data, or protected health information (PHI).

You will need to assess the severity of each asset's threat exposure as soon as your assets have been prioritized. Anything less may be too vague to be applicable to your IT remediation teams, wasting time remediating low- or no-risk vulnerabilities.

Most organizations today prioritize vulnerabilities using one of two methods: either they use the Common Vulnerability Scoring System (CVSS) to identify which vulnerabilities should be addressed first, or they accept the prioritization offered by their vulnerability scanning solution. It is imperative to remember that prioritization methods and the data that support them must be revisited regularly.

Prioritization is critical because the average business has millions of cyber vulnerabilities, yet even the most experienced teams can only remediate about 10% of them. According to a VMware study, 50% of cyberattacks today do not only target a network, but also those connected via a supply chain. So prioritize vulnerabilities reactively and proactive.

What do you do with the data you collected during the prioritization stage? Of course, youll develop a strategy for treating or patching the identified flaws in the order of their severity. There are a variety of strategies to treat or patch vulnerabilities to make the workflow simpler:

  • Acceptance: You can accept the risk of the vulnerable asset to your system. For noncritical vulnerabilities, this is the most likely solution. When the cost of fixing the vulnerability is much higher than the costs of exploiting it, acceptance may be the best alternative.
  • Mitigation: You can reduce the risk of a cyberattack by devising a solution that makes it tough for an attacker to exploit your system. When adequate patches or treatments for identified vulnerabilities arent yet available, you can use this solution. This will buy you time by preventing breaches until you can remediate the vulnerability.
  • Remediation: You can remediate a vulnerability by creating a solution that will fully patch or treat it, such that cyberattackers cannot exploit it. If the vulnerability is known to be high risk and/or affects a key system or asset in your organization, this is the recommended solution. Before it becomes a point of attack, patch or upgrades the asset.

After you've resolved any flaws, make sure to double-check your work. This will reveal whether or not the steps taken were successful and if additional issues have arisen concerning the same assets. Verification adds value to a vulnerability management plan and increases its efficiency. It allows you to double-check your work, mark issues off your to-do list, and add more if necessary.

Verifying vulnerabilities gives you proof that a specific vulnerability is still present, which aids you in your proactive effort to safeguard your system against malicious attacks. It also allows you to observe vulnerability patterns in different sections of your network over time.

The IT team, executives, and other employees must be aware of the present threat level associated with vulnerabilities. IT must provide tactical reporting on detected and remedied vulnerabilities (by comparing the most recent scan with the previous one). The executives need an overview of the present situation of exposure (think red/yellow/green reporting). Other employees must also be aware of how their internet activity may harm the company's infrastructure.

Your organization must learn from past difficulties in order to be prepared for future threats. Reports strengthen your IT team's capacity to address emerging threats when they arise. Moreover, consistent reporting assists your security team in meeting risk management goals as well as regulatory requirements.

In 2022, here are the top 8 best practices for vulnerability management policy.

Vulnerability management protects your network from intrusions, but only if you utilize it to its full potential and follow industry best practices. In 2022, you may enhance your company's security and get the most out of your vulnerability management program by following these top eight best practices for vulnerability management.

As your company grows, your accessible assets and potentially vulnerable entry points expand. It's critical to be aware of any assets in your current software systems, such as individual terminals, internet-connected portals, accounts, and so on. One piece of long-forgotten hardware or software might be your fault. They may appear harmless, sitting in the corner with little or no use, but they are often vulnerable points in your security infrastructure that potential hackers are eager to exploit.

It's important to keep an eye on any potential flaws when you know everything about your organization. Be sure to maintain all of your data, whether it's software or hardware. It's difficult to protect assets that you've forgotten about.

While your organization's IT experts will handle the majority of the work related to vulnerability management, your entire organization should be involved. Employees must be properly informed about how their online activities can jeopardize the organization's systems, and should be kept informed and updated about common breaches that might enable hackers to gain access to sensitive data.

The rise in cybercrime and phishing attacks has resulted in a significant jump in remote work. Many IT professionals who now work remotely have little or no knowledge of cyberattacks. Other employees must know how to secure their Wi-Fi while working remotely.

Vulnerability scanning solutions come in a wide range of forms, but some are superior to others, as they often include a console and scanning engines. The ideal scanning solutions should be simple to use so that everyone on your team may use them without extensive training. Users may concentrate on more complicated tasks when the repeated steps have been automated.

Look into the accuracy of the scanning solutions you are considering. The ones that trigger false alarms might cost you money and time as your security teams will have to perform manual scanning. Your scanning program should also allow you to create detailed reports that include data and vulnerabilities.

The frequency with which you perform vulnerability scanning determines the effectiveness of vulnerability management. Regular scanning is the most efficient way to detect new vulnerabilities as they arise, whether as a result of unanticipated issues or as a result of new vulnerabilities introduced during upgrades or program modifications.

Moreover, vulnerability management software can automate scans to be performed regularly and during low-traffic periods. Even if you do not have vulnerability management software, it is probably still beneficial to have one of your IT team members do manual checks regularly to be cautious.

Adopting a routine infrastructure scanning strategy helps bridge the gap that can put your system at risk of fresh threats at a time when attackers are constantly improving their methods. Scanning your devices on a weekly, monthly, or quarterly basis can help you stay on top of system weaknesses and add value to your business.

Your cybersecurity teams must classify vulnerabilities according to the degree of risk they pose to your organization's assets. This allows IT professionals to focus on remediating the assets that pose the greatest danger to your organization, such as all internet-connected devices in your organization's systems.

Similarly, using both automated and manual asset assessments can help you prioritize the frequency and scope of assessments that are required, based on the risk value assigned to each of them. A high-risk asset only requires a general vulnerability scan.

Even if no vulnerabilities are discovered, your scanning findings must be documented regularly. This allows your IT department to keep a digital trail of scan findings, which may assist your IT department in identifying scan flaws later on, if a potential vulnerability is exploited without the scanner recognizing it. It's the most efficient way to ensure that future scans are as accurate and efficient as possible.

Always ensure that the reports are written in a way that is understandable not only by the organizations' IT teams, but also by the nontechnical management and executives.

Remediation must take shape in the context of a world where patching isnt the only solution. Other remediation strategies include shutdown of a process, session, or module. From vulnerability to vulnerability, the best remediation technique (or a combination of methods) will vary.

To achieve this best practice, the organization's cumulative vulnerability management expertise should be used to maintain an understanding of how to match the appropriate remediation strategy to a vulnerability. It is also reasonable to utilize third-party knowledge bases that leverage massive amounts of data.

Most organizations have several teams working on addressing vulnerability. For instance, the security team is responsible for detecting weaknesses, but it is the IT or devops team that is expected to remediate. Collaboration is essential to establish a closed detection-remediation loop.

Will you be confident that you know the answer when asked how many endpoints or devices are on your network right now? It's also critical to have a single source of truth for that data so that everyone in the company can make informed decisions based on the same information.

Be more cautious than the attackers.

As you continually improve your cloud services, mobile devices, apps, and networks in your organization, threats and cyberattacks have the opportunity to grow. With every change, there is a possibility that attackers will intrusion and steal your vital information.

If you hire a new affiliate partner, employee, client, or customer, your company will be exposed to new opportunities as well as new threats. To protect your company from these threats, youll need a vulnerability management system that can keep up with and respond to all of these developments. Attackers will always be one step ahead if this is not done.
