14 Most Common Types of Cyber Attacks (and How to Prevent Them)
Types of cybersecurity tools
Network security tools
Network security tools are designed to protect the integrity, confidentiality, and availability of the data flowing through your network. They act as the first line of defense, preventing unauthorized access and mitigating attacks on your network infrastructure.
Firewalls:
- Scope: Firewalls serve as gatekeepers for your network, controlling inbound and outbound traffic based on predefined security rules.
- How they work: Firewalls inspect packets of data entering or leaving the network, determining whether to allow or block traffic based on established rules. They can be either hardware or software-based and are essential in preventing unauthorized access to the network.
- Protection against threats: Firewalls filter potentially malicious traffic to defend against unauthorized access, including hacking attempts, malware, and Denial-of-Service (DoS) attacks.
Intrusion Detection Systems (IDS):
- Scope: IDS tools monitor network traffic for suspicious activity and policy violations, alerting administrators to potential threats.
- How they work: IDS analyzes network traffic in real-time, looking for patterns that match known attack signatures or anomalies that indicate a potential breach. When a threat is detected, it alerts the security team for further investigation.
- Protection against threats: IDS helps identify and respond to threats like unauthorized access, malware infections, and insider attacks, offering an additional layer of security by catching what firewalls might miss.
Virtual Private Networks (VPNs):
- Scope: VPNs create a secure and encrypted connection over the internet, allowing remote users to access the organization’s network securely.
- How they work: VPNs encrypt data as it travels between the user’s device and the organization’s network, making it unreadable to anyone who intercepts it. This ensures that sensitive information is protected, even on unsecured networks.
- Protection against threats: VPNs protect against data interception, eavesdropping, and man-in-the-middle attacks by ensuring that all transmitted data remains encrypted and secure.

Endpoint security tools
Endpoint security tools focus on securing individual devices, or endpoints, such as computers, smartphones, and tablets, that connect to the network. Since each endpoint can be a potential entry point for attackers, securing these devices is crucial.
Antivirus software:
- Scope: Antivirus software is a fundamental tool that protects against known malware and viruses.
- How it works: Antivirus programs scan files and programs on a device for known malware signatures. When they detect a match, they either quarantine or remove the malicious file to prevent it from causing harm.
- Protection against threats: Antivirus software protects against viruses, worms, Trojans, spyware, and other types of malware that could compromise an endpoint’s security.
Endpoint Detection and Response (EDR) tools:
- Scope: EDR tools offer advanced security by continuously monitoring endpoint activities for signs of suspicious behavior and responding to threats in real time.
- How they work: EDR tools collect and analyze data from endpoints, looking for indicators of compromise (IOCs) such as unusual file modifications, unauthorized access attempts, or strange network traffic. They can automatically isolate compromised endpoints to prevent the further spread of an attack.
- Protection against threats: EDR tools protect against sophisticated threats like ransomware, zero-day exploits, and advanced persistent threats (APTs) by detecting and responding to malicious activity before it can escalate.

Application security tools
Application security tools focus on securing your organization's software applications, particularly those accessible over the web. These tools help prevent attackers from exploiting application vulnerabilities.
Web Application Firewalls (WAF):
- Scope: WAFs protect web applications by filtering and monitoring HTTP/HTTPS requests and blocking malicious traffic.
- How they work: WAFs analyze the data that users send to web applications, looking for common attack patterns such as SQL injection, cross-site scripting (XSS), and other web-based exploits. The WAF blocks or sanitizes these requests before they reach the application.
- Protection against threats: WAFs guard against web-based attacks that target application vulnerabilities, such as SQL injection, XSS, and distributed denial-of-service (DDoS) attacks.
Static and Dynamic Application Security Testing (SAST/DAST):
- Scope: SAST and DAST are tools used to identify vulnerabilities in software during the development and testing phases.
- How they work: SAST analyzes an application’s source code, binaries, or bytecode for vulnerabilities without executing the program, identifying security flaws early in the development cycle. DAST, on the other hand, tests the application in its running state, simulating attacks to uncover vulnerabilities that may not be visible in the code.
- Protection against threats: SAST/DAST tools protect against code-level vulnerabilities, including logic errors, insecure coding practices, and issues that could be exploited by attackers once the application is live.

Data security tools
Data security tools are designed to protect your organization’s data—both at rest and in transit—from unauthorized access, tampering, and breaches.
Encryption tools:
- Scope: Encryption tools secure data by converting it into an unreadable format that can only be decoded with the correct decryption key.
- How they work: Encryption tools apply algorithms to data, transforming it into ciphertext. Only users with the correct decryption key can convert this ciphertext back into its original, readable format.
- Protection against threats: Encryption tools protect against data breaches, unauthorized access, and data interception, ensuring that even if data is stolen, it remains useless to the attacker.
Data Loss Prevention (DLP) solutions:
- Scope: DLP solutions prevent sensitive data from leaving the organization, whether intentionally or accidentally.
- How they work: DLP tools monitor and control data flow across networks, devices, and applications. They enforce policies that restrict the sharing, copying, or transferring of sensitive information to unauthorized users or locations.
- Protection against threats: DLP solutions protect against data breaches, insider threats, and accidental data loss by ensuring that sensitive information is not exposed or transferred inappropriately.
Identity and access management (IAM) tools
IAM tools manage and control access to resources within an organization, ensuring that only authorized individuals can access sensitive information and systems.
Multi-factor authentication (MFA):
- Scope: MFA adds an extra layer of security by requiring multiple verification forms before granting access to a system or resource.
- How it works: MFA combines something the user knows (like a password) with something the user has (like a smartphone app) or something the user is (like a fingerprint) to verify identity before granting access.
- Protection against threats: MFA protects against unauthorized access, phishing attacks, and credential theft by requiring more than just a password for authentication.
Single Sign-On (SSO) solutions:
- Scope: SSO solutions streamline the user authentication process by allowing users to access multiple applications with a single set of credentials.
- How they work: SSO authenticates users once and then grants them access to all the connected systems and applications without requiring them to log in again.
- Protection against threats: SSO protects against password fatigue and reduces the risk of credential-related breaches by minimizing the number of passwords users need to manage while still enforcing strong authentication practices.
