What Is Network Security Threats?

Network security threats are any form of action that attempts to access, damage, steal, or disrupt the integrity, confidentiality, and availability of data and network services. These threats can come from various sources, both internal and external, and can cause financial loss, reputation, and operational disruption.

Relationship Between Network Security Threats and Computer Security Threats

Network security threats and computer security threats are closely related because both relate to the protection of data and information systems. However, computer security threats focus more on individual devices, such as computers and servers, while network security threats are broader in scope, encompassing the entire network infrastructure, including hardware, software, and data flowing through the network.

10 Network Security Threats

Today, there are various types of network security threats that you should be aware of. Here are ten types of threats to watch out for. Read carefully!

1. Malware

Malware is malicious software designed to damage or disrupt computer systems and networks. Types of malware include viruses, worms, trojans, and ransomware. Malware can enter a network through malicious downloads, or through infected devices. Once inside, malware can spread and cause significant damage, such as stealing data, corrupting files, or locking systems until a ransom is paid.

2. Phishing

Phishing is a technique used by attackers to obtain sensitive information such as passwords and credit card numbers by masquerading as a trusted entity in a digital communication medium. Phishing is usually carried out through email or a fake website. Phishing emails often appear to come from a legitimate source, such as a bank or online service, and ask users to click on a link that leads to a fake site.

3. DDoS (Distributed Denial of Service)

DDoS attacks aim to make online services unavailable by overwhelming a server or network with massive amounts of traffic. These attacks can cause significant downtime and financial losses. DDoS attacks often use botnets, which are networks of computers that have been infected with malware and are controlled by an attacker without the knowledge of their owners.

4. Man-in-the-Middle (MitM) Attacks

In a MitM attack, an attacker positions himself between two communicating parties, with the goal of stealing or manipulating the information being transmitted. This attack can occur on unsecured public networks, such as public Wi-Fi. The attacker can access the data being transferred between the two parties and even insert false or malicious information.

5. SQL Injection

SQL injection is an attack in which an attacker injects malicious code into a website input form to access and manipulate the database. This can result in data theft and database corruption. This attack often occurs in web applications that do not properly validate user input, allowing the attacker to execute malicious SQL commands.

6. Spyware

As the name suggests, spyware is software designed to monitor a user’s activities without their knowledge. Spyware can steal personal information and other sensitive data. Spyware is often hidden in legitimate-looking software and can record keystrokes, browsing history, and other information without the user’s knowledge.

7. Password Attacks

Password attacks are attempts to obtain a user’s password using various methods, such as brute force or dictionary attacks. These attacks aim to gain unauthorized access to systems and data. In a brute force attack, the attacker tries various password combinations until he succeeds. In a dictionary attack, the attacker uses a list of common passwords to try to log into an account.

8. Rogue Access Points

Rogue access points are unauthorized network devices installed without permission and are often used by attackers to gain access to a corporate network. These access points can be entry points for other attacks. Attackers can use these points to eavesdrop on communications or launch further attacks on other devices on the network.

9. Eavesdropping

The next network security threat is eavesdropping. This threat is the act of stealing data sent over a network, such as VoIP conversations or credit card data. Attackers use special devices or software to capture and analyze data sent over an unsecured network.

10. Spoofing

Spoofing is a technique where an attacker impersonates another device or IP address to launch an attack. For example, in IP spoofing, an attacker sends data packets with a fake sender IP address to make it look like it came from a trusted source. The goals can range from stealing data to launching a DDoS attack.

How to Overcome Network Security Threats

Preventing and overcoming network security threats requires the right strategies and methods. Here are seven effective ways to protect your network from security threats.

1. Implement a Firewall

A firewall is a software or hardware that functions as a network gatekeeper. The way it works, the firewall will monitor and control network traffic based on predetermined security rules to prevent unauthorized access and dangerous threats from entering the network.

2. Use Antivirus and Anti-Malware

Using Antivirus and anti-malware will help you to detect and remove malware from your devices and networks. In order to function properly, this software must be updated regularly to recognize new and evolving threats.

3. Implement Access Control

Access control involves restricting access to the network and data to authorized users only. This includes the use of strong passwords, two-factor authentication (2FA), and user privilege management. By restricting access, you can reduce the risk of data leaks or unauthorized access to sensitive information.

4. Updating Software Regularly

Update your software and operating system regularly to patch newly discovered security holes. Many attacks are successful because the weaknesses are already known to the attackers. Therefore, make sure all devices, including routers and IoT devices are updated with the latest security patches.

5. Educating Employee

Providing cybersecurity training to employees is essential to increase their awareness and understanding of network security threats. Educated employees can be the first line of defense in preventing attacks. This training can be conducted on recognizing phishing emails, safe password practices, and actions to take if a security breach is suspected.

6. Backup Data Regularly

Regularly back up your data to prevent data loss due to attacks or system failures. Backups should be done regularly and stored in a secure location, separate from the main network. By having up-to-date backups, you can quickly recover data lost or damaged due to network security attacks.

7. Use a Professional Network Security Service

Professional network security services from a trusted IT company can provide comprehensive protection. They have the expertise and resources to effectively manage network security, including network monitoring, threat detection, and incident response. These services can help companies save time and money while ensuring their networks remain secure.
