Cyberattacks are getting more advanced, and businesses are paying the price. According to IBM’s Cost of a Data Breach Report 2024, the average breach cost hit $4.88 million. Hackers exploit network security vulnerabilities daily, causing data loss, system disruptions, and financial damage.
Neal Juern, CEO of 7tech, says “Cybercriminals don’t need a complex attack when simple security gaps exist. If your business isn’t securing its network proactively, you’re already at risk.”
Your business depends on secure systems. If attackers find weaknesses, they can infiltrate your network, steal data, and cripple operations. Identifying and closing these gaps is critical.
In this blog, you will learn about the most common network security vulnerabilities, how to identify them, and actionable steps to protect your business from potential threats.

The Growing Risks of Network Security Vulnerabilities
Cybercriminals constantly evolve their tactics. Many businesses still use outdated security measures, creating gaps that attackers easily exploit.
- Complex IT environments introduce risks: The adoption of cloud services and remote work has expanded attack surfaces. Many organizations fail to secure these changes properly, paving the way for network vulnerabilities that hackers can exploit.
- Automated tools make attacks easier: Cybercriminals use advanced scanning tools to find weaknesses. If your business has exposed ports, weak passwords, or outdated software, attackers will find and exploit them.
- Non-compliance can lead to legal consequences: Regulations like HIPAA and PCI DSS require strong security controls. Failing to protect network security vulnerabilities can result in lawsuits, fines, and loss of customer trust.
Ignoring these risks isn’t an option. You need to understand the types of vulnerabilities in network security and how to address them before they lead to a breach.
Types of Network Security Threats That Put Your Business at Risk
Hackers use various tactics to exploit network security vulnerabilities. These attacks cause downtime, financial losses, and data theft.
Malware and Ransomware Attacks
Malware infiltrates networks through phishing emails, infected downloads, or software vulnerabilities. Ransomware locks files until a ransom is paid, often crippling businesses for days.
- Ransomware attacks surged by 73% in 2023. Attackers encrypt critical data and demand payment, leading to costly downtime and loss of revenue.
- Many victims pay the ransom but never regain access to their data. Some attackers delete files even after payment.
- Proper network segmentation, endpoint security, and continuous backups reduce the risk of malware spreading across systems.
Phishing and Social Engineering
Cybercriminals trick employees into revealing sensitive information. These attacks bypass firewalls and target human error.
- Over 90% of cyberattacks start with phishing. Attackers use fake emails to steal credentials and spread malware.
- Hackers impersonate executives, vendors, or IT teams to trick employees into transferring funds or exposing confidential data.
- Security awareness training, email filtering, and multi-factor authentication help employees recognize and prevent phishing attempts.
Zero-Day Exploits and Unpatched Systems
Hackers take advantage of unpatched software vulnerabilities. Zero-day exploits are attacks launched before vendors release a fix.
- Unpatched systems are a leading cause of information security vulnerabilities. Even a single outdated application can create an entry point for attackers.
- Cybercriminals sell zero-day vulnerabilities on the dark web, allowing attackers to breach networks before security patches are available.
- Routine updates, patch management, and security monitoring help businesses beat zero-day threats.

Insider Threats and Human Error
Employees and contractors may unintentionally or deliberately expose sensitive data.
- Staff and insider threat actors are responsible for 60% of insider cyber incidents. Negligent employees or malicious insiders can compromise security.
- Poor access control increases the risk of insider data theft. If employees have unnecessary access to sensitive files, attackers can exploit this.
- Role-based access, strict authentication measures, and security monitoring reduce the likelihood of insider threats.
Common Network Vulnerabilities You Need to Address
Weak security controls make it easy for attackers to gain access. These common network vulnerabilities are among the biggest risks for businesses.
Weak Passwords and Credential Theft
Passwords remain a major security issue. Stolen or weak credentials allow attackers to infiltrate systems.
- Over 80% of hacking incidents involve stolen credentials. Attackers use brute-force attacks or steal passwords through phishing.
- Multi-factor authentication (MFA) blocks unauthorized logins by adding an extra layer of security beyond passwords.
- Password managers generate and store complex passwords securely, reducing reliance on easily guessed credentials.
Poorly Configured Firewalls and Security Tools
Misconfigurations leave security gaps, allowing attackers to bypass defenses. An analysis of over 40 million exposures reveals that 80% are due to misconfigurations.
- Firewalls should block unauthorized traffic, but misconfigured settings create vulnerabilities. Open ports or weak filtering rules expose networks to attacks.
- Regular security audits identify and fix cybersecurity vulnerabilities, reducing the risk of an undetected attack.
- Continuous monitoring and log analysis help detect unusual activity before it becomes a serious threat.
Unsecured APIs and Third-Party Risks
APIs connect systems but can expose cyber vulnerabilities if left unsecured. Over the past three years, the percentage of organizations reporting API security incidents has steadily increased, reaching 84% in 2024.
- Weak authentication allows attackers to manipulate APIs, gaining access to sensitive business data.
- Third-party vendors often introduce security risks. If their systems are compromised, attackers may access your network.
- Strict API access controls, encryption, and regular security assessments prevent unauthorized connections and data leaks.
How to Strengthen Your Network Against Threats
Businesses must stay ahead of cyber threats and vulnerabilities by improving security measures. Let’s discuss 3 methods you can explore to tighten your cybersecurity.
1. Implementing a Zero-Trust Security Model
Zero trust requires continuous verification for access to systems and data.
- Traditional security assumes internal networks are safe. Zero trust removes that assumption by requiring strict identity verification.
- Role-based access limits user permissions to only what they need, reducing the impact of compromised accounts.
- Network segmentation prevents attackers from moving laterally if they breach a system, containing potential damage.
2. Advanced Threat Detection and AI Security Solutions
AI-driven security detects and blocks threats in real-time. CyberArk’s Threat Landscape Report shows that 99% of organizations use AI in their cybersecurity defense initiatives.
- AI can analyze patterns to spot various types of attacks in network security before they escalate, reducing the time it takes to detect breaches.
- Automated response tools contain threats before they cause major damage, minimizing downtime and data loss.
- Threat intelligence helps businesses outpace emerging cyber threats, ensuring proactive defense strategies.
3. Employee Training and Cyber Awareness
Employees are the first line of defense against cyberattacks. According to CloudSecureTech, external actors are responsible for 65% of breaches, while employees account for 35% of breaches, mostly due to errors rather than malicious intent.
- Regular training reduces human error, a key cause of vulnerabilities in network security. Employees must learn how to recognize phishing attempts and suspicious activity.
- Simulated phishing tests help employees recognize real threats in a controlled environment.
- Clear security policies ensure employees follow best practices, reducing the likelihood of accidental security lapses.
Preventing Network Security Vulnerabilities with Proactive Strategies
Many businesses fail to act until after a cyberattack occurs. Taking proactive security steps is essential to staying ahead of threats.
Below is a breakdown of key preventive measures and their impact on securing networks.
| Preventive Measure | How It Strengthens Security |
| Regular Penetration Testing | Identifies types of vulnerabilities in network security before attackers can exploit them. |
| Network Segmentation | Limits attackers’ movement inside a network, containing potential breaches. |
| Real-Time Threat Monitoring | Detects types of network security threats as they happen, allowing for immediate response. |
| Incident Response Planning | Prepares businesses to act quickly in the event of an attack, minimizing damage. |
