Most Common Cybersecurity Vulnerabilities

Table of Contents

While it’s impossible to avoid all cyber threats, there are several common vulnerabilities that you can address to help minimize your risk. This blog post will discuss the most common cybersecurity vulnerabilities and how to protect yourself against them.

As businesses and consumers become more reliant on technology, cyber-attack risk increases. According to a report by Cisco, there were 1.2 million confirmed cyber attacks in 2021 alone.

A vulnerability in cybersecurity

Identifying cyber vulnerabilities is one of the most important steps organizations can take to improve and strengthen their overall cybersecurity posture.

A vulnerability in a host or system, such as missed software updates or misconfigured systems, has been exploited by criminals who want access for malicious purposes. This will allow them more excellent avenues into your business’s IT resources which could lead to more compromising about what information they might steal from you when trying to do so.


Vulnerabilities are the underlying cause of many security problems. In cybersecurity, they’re a weakness that malicious actors can exploit to access your network and gain complete control over it from within their environment; this could mean malware infection or password theft.


A threat intends to exploit any vulnerability and cause harm. Their objective may be financial gain, but they will also take advantage if there’s an opportunity; usually, this means data theft or destruction on-site (such as through malware).

The most common types include ransomware which requires payment every month before users can re-access their files, and spear phishing, where fake emails are sent out with links that lead directly back into malicious software.


Cybersecurity is a hot topic these days. Understanding the risks associated with cyber threats and how to protect yourself from them as an organization or individual is essential.

Top ten common cyber security vulnerabilities

Cybersecurity vulnerabilities are within your company’s control, not that of cybercriminals. You can proactively manage them by taking the appropriate action and employing the proper tools, which will help keep you safe from those who only want to cause harm.


Misconfigurations are the single most significant threat to both cloud and app security. These errors transform your organization’s workload into an obvious target that can be easily discovered with a web crawler, but it doesn’t stop there.

The absence of perimeter defense within this new environment compounds risks even further because humans often make mistakes when automating processes like configuration management which is why automation should play such a significant role in reducing them as much as possible

A few miscellaneous notes about how poorly configured apps were exploited during recent breaches:

1. Misconfigurations are the single most significant threat to cloud and app security, as they allow hackers easy access to sensitive data and other valuable information.

2. Automation can help reduce misconfigurations by ensuring that processes such as configuration management are carried out consistently and accurately.

3. Unfortunately, even with careful automation, humans can still make mistakes that can lead to severe breaches. For example, a recent breach at Equifax was caused by an employee who failed to install a security patch for a vulnerable server application, exposing users’ data to attack.

4. To prevent such incidents, organizations need to be aware of the potential risks of misconfigurations and take steps to reduce them through robust security controls, regular audits, and ongoing employee training.

5. By proactively addressing misconfiguration, organizations can ensure that their cloud and app environments are secure, minimizing the risk of a costly breach or data leaks.

Unsecured APIs

APIs provide a digital interface that enables applications or components of applications to communicate with each other over the internet.

APIs are an easy target for hackers who want access to your network. Still, they can also be used carefully and appropriately to deliver beneficial features like remote employee monitoring without compromising security standards, so long as proper precautions have been taken beforehand.

A common vulnerability occurs when these interfaces aren’t adequately secured; attackers will need one wrong click (or successful exploit) before breaking through any protections you put up against them.

So how do you effectively use APIs without exposing yourself to security flaws and risks? The first step is to take a comprehensive approach, evaluating your existing API usage and performing risk assessments on any new interfaces you might introduce.

In addition, it’s essential to be aware of all the elements involved in API creation and management, including authentication, authorization, and data encryption.

With the rise of cloud services, security has become a top priority for IT teams. Even with the best efforts and proper precautions developers take during development, it’s easy to overlook essential risks when you’re coding away without any feedback from your environment.

To help combat this issue, we recommend conducting training sessions on how encryption works in different environments like traditional systems or software and keeping secrets confidential between colleagues who may not yet know about specific features and functionalities available only via API access.

Outdated or unpatched software

As with system misconfigurations, it is crucial to keep your software up-to-date. Software vendors periodically release application updates containing new features or functionalities and patch any known cyber and computer security vulnerabilities.

However, if you wait to apply these patches, in that case promptly, cybercriminals will be able to exploit any unpatched vulnerabilities and weaknesses left vacant by unpatched outdated applications making them easy targets for hackers looking into potential crimes like identity theft.

To help address this issue, organizations should develop and implement a process for prioritizing software updates. They can do so by utilizing tools that will automate the activity of patching systems or even just creating lists based on what needs updating and when (such as those generated using production monitoring data).

The more processes are automated in an IT environment like these, especially ones related to priorities constantly shifting through different types of threats, potential targets changing daily due to new releases coming out every week.

The less time humans spend handling tedious manual tasks, which would otherwise take away from higher-value work such as identifying new patches and threats. Value is added to the organization because they are not wasting time fixing bugs that do not put their systems at risk; instead, they can devote more resources to addressing potential hazards (such as zero-day vulnerabilities).

They can also make changes based on an analysis of data regarding trends, updates, and other relevant information that would otherwise be overlooked if left in the hands of humans. Employees can also be freed up to perform additional, higher-value organizational tasks rather than just prioritizing patches and updates.

Zero-day vulnerabilities

Network vulnerabilities are a pain in the neck, but luckily you’ve got some time before they become an issue. That is unless your company scraps together money for server maintenance or updates on their software, in which case there will be no fixing these pesky bugs.

The dark art of cyberattacks is severe, but it doesn’t have to be profitable. Zero-day attacks are complex for anyone, even companies in the tech industry, to detect and stop because they’re so stealthy.

To effectively manage these threats, you need prevention technology and an effective response plan should there ever come a time when your company’s assets get hacked.

In order words: deploy next-generation antivirus (NGAV), endpoints detection & response(EDR) coupled with threat intelligence today before tomorrow becomes too late.

Weak or stolen user credentials

Creating unique passwords for each account is essential whether you’re a business or personal user. This will help protect against cybercriminals who reuse and recycle credentials to gain unauthorized access as soon they guess what kind-of system someone might have signed up with (like trying out different usernames and passwords).

If these attacks are successful, then crocheting together an entity capable enough to brute force its way into any sensitive data store on the internet. This includes computers running Microsoft Windows operating systems, and the attacker could quickly move laterally within the same network and gain unauthorized access.

Organizations should set and enforce clear policies that require strong, unique passwords. Policies can also include multifactor authentication (MFA), which requires more than one form of identification, such as a password and something else like fingerprints, to prove you’re who you say on screen; this makes logging onto an account even harder for would-be hackers.

Unauthorized access control

(POLP) The principle of least privilege is a safety conception and procedure that provides users restricted permit privileges based on the duties required for their job, which organizations have widely adopted to strengthen cybersecurity practices within businesses or government agencies.

The idea behind this strategy is to allow us as consumers to have more control over our data when accessed through systems like Facebook; because only those who need specific permissions should be able to do so without question while also monitoring what they’re doing concerning their data and keeping a record so you can see if any harm has been done. Before explaining the principle of least privilege, it is first essential to understand an information system.

Runtime threats

The “shared responsibility model” means that while much of the infrastructure is secured by cloud service providers, organizations are still responsible for everything else. This includes operating systems, applications, and data security. This can be misunderstood as your sensitive information will always stay protected in a public environment when it relies on you (the user).

The cloud provides a vehicle for storing and delivering data but also makes organizations more susceptible to cyberattacks. This is because traditional security measures do not work in the environment of shared resources across various devices with remote access capabilities.

Instead, we must supplement our efforts using advanced technologies like machine learning or behavioral analytics that can detect threats before they become critical software vulnerabilities.

Code injection vulnerabilities

A code injection attack occurs when a vulnerability allows malicious actors to introduce their custom-added codes. This threat typically leads to data breaches, flow changes, or loss of confidentiality. Still, it also has other more severe implications for availability and integrity, depending on how sophisticated they are with injections.

This can be anything from changing something within an SQL query command instead of just adding some extra characters at the end, as we might expect if using UNION operators in our queries (which would not do any damage).

Software supply chain

Modern software development has moved to an end-to-end model where we source our core components from a supply chain.

The complexity and lack of control over every part in this stack can represent risks that need addressing, such as typo-squatting or dependency confusion attacks on your app’s availability via malware introduction into these systems at different points along their path until it reaches you, the developer who doesn’t know what they’re doing.

IoT devices

But why are we paying so much attention to IoT? It’s not just about the smart devices that connect our everyday lives, and it’s also a massive security risk for businesses.

The Internet of Things (IoT) contains multiple “smart” gadgets, such as Wi-Fi printers, TVs, and refrigerators; however, these can be compromised by hackers to form networks with exploited tools carrying out different attacks on behalf of the business whose vulnerabilities remain unknown because they don’t have proper protections put in place.

IoT has become a hot topic recently, but it can be easy to overlook the critical security risks that come with this new technology. The IoT aims to help us streamline and simplify our lives, from remotely monitoring our homes and workplaces to automating everyday tasks like turning lights on and off or adjusting the temperature in our homes.

Cyber security vulnerability management

Vulnerability assessments and management is identifying, assessing, and reporting cybersecurity vulnerabilities across endpoints and workloads.

Vulnerabilities can be found in any aspect of an organization’s IT environment, so a strong program uses threat intelligence to prioritize risks while also remediating them quickly with improved knowledge about how things work behind the scenes to ensure the infrastructure is secure.

Vulnerability management programs are necessary for organizations that want to protect their sensitive data and ensure compliance with government regulations such as HIPAA and PCI. By leveraging a comprehensive vulnerability scanning solution, companies can identify weaknesses across different parts of their IT systems before cybercriminals can exploit them or regulators can issue fines for noncompliance.

What makes a good vulnerability management program?

Critical elements of a robust vulnerability management system include using threat intelligence to prioritize risks based on the likelihood and impact of a vulnerability being exploited and automating security tasks so that resources can be focused on preventing attacks instead of chasing down vulnerabilities.

Additionally, organizations must regularly evaluate their programs’ effectiveness by performing validation scans showing how well their security controls protect against attacks.

Vulnerability management is essential to any cybersecurity strategy and requires a combination of tools, processes, and expertise to keep endpoints and workloads secure. By implementing the right program, organizations can effectively identify weaknesses before they become problems and protect their sensitive data from being compromised.


Although it would be impossible to list every possible cybersecurity vulnerability, we’ve highlighted some of the most common ones you should watch out for.

By being aware of these threats and taking the necessary precautions, you can help keep your business and customer data safe from harm. For more information on protecting your organization from cybercrime, check our website or contact us for a consultation. Thanks for reading.
