What is Vulnerability in Cyber Security: Meaning & Definition

In today's world of advanced digital security, it is important to understand the concept of cyber security vulnerabilities.

In simple terms, cyber security vulnerabilities refer to the potential weaknesses and loopholes in digital systems that hackers can exploit to gain unauthorised access and disrupt services.

These vulnerabilities could range from software bugs and misconfigurations to social engineering tactics and weak passwords.

As technology evolves and we become more reliant on digital systems, the threat to these vulnerabilities only increases.

It is crucial to stay informed and updated on cyber security threats and vulnerabilities to protect yourself and your organisation from any potential threats.

Here are the major differences between threat and vulnerability in cyber security:

Definition

Threats and vulnerabilities are two concepts that are closely related to cyber security. A threat is any potential danger or harm that can be caused by an outside source, such as a hacker or malware. A vulnerability is a weakness in a system or network that can be exploited by a threat.

Source of Origin

The source of origin for threats and vulnerabilities is different. Threats originate from external sources, such as hackers and malicious software, while vulnerabilities originate from internal sources, such as poor coding or outdated systems.

Impact on Systems

Threats have the potential to cause significant damage to systems, while vulnerabilities can make systems more susceptible to attack but do not necessarily lead to damage if they are not exploited.

Mitigation Strategies

The strategies for mitigating threats and vulnerabilities are also different.

To mitigate threats, organisations must implement measures such as firewalls and antivirus software that can detect and block malicious activity before it causes damage.

To mitigate vulnerabilities, organisations must address the underlying weaknesses by patching software, updating systems, and implementing better security practices.

Why is Cyber Security Vulnerability Becoming Exploitable?

Here are the four main reasons for cyber security vulnerability becoming exploitable.

1. Increased Use of Technology

As technology has become increasingly integrated into our daily lives, the need for cyber security has grown exponentially.

The increased use of technology has resulted in an increase in potential vulnerabilities that can be exploited by malicious actors.

This is especially true as more and more devices are connected to the internet, creating a larger attack surface for hackers to target.

2. Lack of Security Awareness

Many users lack the knowledge and understanding of how to protect themselves from cyber threats.

Without proper security awareness training, users can easily fall victim to cyber attacks through phishing emails, social engineering tactics, and other malicious activities.

3. Outdated Software

Outdated software is one of the most common causes of cyber security vulnerabilities becoming exploitable.

Older versions of software often contain known vulnerabilities that have not been patched or updated, leaving them open to exploitation by hackers who are looking for easy targets.

4. Poorly Configured Systems

Another major cause of cyber security vulnerability becoming exploitable is poorly configured systems.

If systems are not properly configured with the latest security patches and updates, they can be easily compromised by attackers who are looking for weaknesses in the system’s defences.

Additionally, if users do not follow best practices when setting up their systems, such as using strong passwords and two-factor authentication, they may leave their systems vulnerable to attack.

Cause of Vulnerability in Cyber Security

Here are the four main cause of vulnerability in cyber security businesses should look into: 

1. Poor Password Management

One of the primary causes of cyber security vulnerabilities is poor password management.

Passwords are used to protect data and systems from unauthorised access, but if they are not properly managed, they can become a weak link in an organisation’s security system.

Poor password management includes using weak passwords, sharing passwords with others, using the same password for multiple accounts, and failing to change passwords regularly.

2. Unpatched Software

Another common cause of cyber security vulnerabilities is unpatched software. Software patches are updates that fix known security flaws in software programs and operating systems.

If these patches are not applied in a timely manner, hackers can exploit the vulnerabilities to gain access to sensitive information or cause other damage.

It is important for organisations to ensure that all their software is up-to-date and patched regularly.

3. Social Engineering Attacks

Social engineering attacks are another major cause of cyber security vulnerabilities.

These types of attacks involve manipulating people into revealing confidential information or granting access to restricted areas by exploiting their trust or lack of knowledge about computer systems and networks.

Common social engineering techniques include phishing emails, phone scams, and malicious websites that appear legitimate but contain malicious code.

4. Unsecured Networks

Unsecured networks can also create cyber security vulnerabilities if they are not properly configured and secured against unauthorised access.

This includes using strong encryption protocols such as WPA2-AES or WPA3-AES for wireless networks, disabling remote access services such as Telnet and SSH when not needed, and using firewalls to block unauthorised traffic from entering the network.

Organisations should also use intrusion detection systems to detect any suspicious activity on their networks as soon as possible so that it can be addressed quickly before any damage is done.

Top 10 Types of Vulnerabilities in Cyber Security

The top 10 types of vulnerabilities in cyber security businesses should look for in 2023-24.

1. Unpatched Software

One of the most common types of cyber security threats and vulnerabilities is unpatched software. This occurs when software is not updated with the latest security patches, leaving it vulnerable to attack.

Hackers can exploit these vulnerabilities to gain access to sensitive information or cause damage to systems.

It is important for organisations to ensure that all their software is up-to-date and patched regularly to prevent such attacks.

2. Phishing Attacks

Phishing attacks involve sending malicious emails or messages that appear to be from a trusted source to trick users into providing sensitive information or downloading malware.

These attacks often use social engineering techniques, such as creating a sense of urgency or offering rewards, to convince users to act.

Organisations should educate their employees about phishing attacks and have policies in place that require them to verify any requests for sensitive information before responding.

3. Malware

Malware is malicious software that can be used by hackers to gain access to a system or steal data. Common types of malwares include viruses, worms, ransomware, and spyware.

It is important for organisations to have effective anti-malware solutions in place to detect and remove any malicious software before it can cause harm.

4. SQL Injection Attacks

SQL injection attacks are one of the most dangerous types of cyber security threats and vulnerabilities as they allow hackers to gain access to databases and steal sensitive information such as credit card numbers or passwords.

Organisations should ensure that their web applications are properly coded and tested for SQL injection vulnerabilities to prevent such attacks from occurring.

5. Insufficient Network Security

Organisations should also ensure that their network is secure by using firewalls, encryption technologies, intrusion detection systems, and other measures designed to protect against data breaches or unauthorised access.

Additionally, organisations should limit access rights on their networks so only authorised personnel can access sensitive data or systems.

6. Unsecured Wi-Fi Networks

Unsecured Wi-Fi networks are also vulnerable targets for hackers as they do not require authentication before allowing devices onto the network.

As a result, hackers can easily intercept traffic sent over these networks and steal confidential data without being detected by the user or organisation hosting the network.

Organisations should always use encryption technologies when setting up Wi-Fi networks to protect against unauthorised access attempts from external sources.

7. Unauthorised Access

Unauthorised access occurs when an individual gains access without permission or authorisation from an organisation’s IT department or other responsible party within the organisation’s infrastructure.

Organisations should implement strong authentication measures such as two-factor authentication (2FA) to prevent unauthorised individuals from gaining access.

Additionally, organisations should limit user privileges so only those who need certain resources have access.

8. Social Engineering Attacks

Social engineering attacks involve using psychological tactics, such as posing as a trusted entity, in order manipulate users into revealing confidential information.

These types of attacks rely on exploiting human weaknesses, rather than technical vulnerabilities, making them difficult for organisations guard against.

Organisations should educate their employees about social engineering tactics, so they are aware of how these types of attacks work.

9. Poor Password Practices

Poor password practices refers to people using weak passwords, reusing passwords across multiple accounts, writing down passwords, sharing passwords with others etc.

Weak passwords increase the likelihood of someone gaining unauthorised access to an account which could lead to serious consequences for an organisation.

Organisations should enforce strong password policies which require users to create unique passwords that are at least 12 characters long with upper case letters, lower case letters, numbers, and special characters included.

10. Data Leakage/Loss

Data leakage/loss refers to when confidential data is inadvertently exposed due to improper storage practices or system failures.

This type of vulnerability can occur if an organisation does not have adequate measures in place to protect its data from being exposed.

To mitigate this risk, organisations must ensure that all their data is securely stored using encryption technologies and regularly backed up offsite so it can be recovered quickly if necessary.

How to Prevent Vulnerability?

Here are ways to prevent vulnerability and threats in cyber security:

1. Use Strong Passwords

One of the most important steps you can take to protect yourself from cyber security threats and vulnerabilities is to use strong passwords.

A strong password should be at least 8 characters long and include a combination of upper- and lower-case letters, numbers, and special characters.

Additionally, it is important to avoid using the same password for multiple accounts.

2. Keep Software Up to Date

It is also important to keep all your software up to date with the latest security patches and updates.

This includes not only operating systems like Windows or macOS, but also web browsers, email clients, and other applications that are installed on your computer or device.

Outdated software can leave you vulnerable to malicious attacks as they may contain known security flaws that have since been patched in newer versions.

3. Be Wary of Suspicious Links and Attachments

Another way to protect yourself from cyber security threats and vulnerabilities is to be wary of suspicious links or attachments in emails or on websites.

Malicious actors often use phishing emails or malicious websites to try and gain access to sensitive information such as passwords or financial data.

If you receive an email with a link that looks suspicious, do not click on it without first verifying its authenticity with the sender.

Additionally, never open an attachment unless you are certain it is safe to do so.

4. Enable Two-Factor Authentication (2FA)

Two-factor authentication (2FA) adds an extra layer of security by requiring users to enter a one-time passcode that is sent via text message or generated by an authenticator app before they can access their account.

Enabling 2FA on any online accounts you have will help protect them from unauthorised access even if someone were able to obtain your username and password through malicious means such as phishing emails or malware infections.

5. Use Antivirus Software

Using antivirus software on your computer can help protect it from viruses, malware, ransomware, and other malicious programs that could potentially compromise your system’s security.

Make sure you choose a reputable antivirus program that offers real-time protection against new threats as well as regular scans for existing ones so that you can stay ahead of any potential threats before they become serious issues for your system’s security.

6. Back Up Your Data Regularly

Backing up your data regularly can save you time and money if something were ever to happen to your computer due to cyber security threats or vulnerabilities such as ransomware infections or hardware failure.

It is important to back up both local files stored on your computer as well as any cloud storage services like Google Drive or Dropbox so that all your data is secure in the event something happens unexpectedly.

7. Monitor Your Accounts Regularly

Finally, make sure you monitor all your online accounts regularly for any suspicious activity such as unauthorised logins from unknown locations or changes made without your knowledge so that you can quickly identify any potential threats before they become serious issues for your system’s security.
