2. Spoofing

Spoofing involves attackers masquerading as other entities by altering communication origins. Methods used by cyber attackers include falsifying email addresses, manipulating IP addresses, and imitating websites to deceive their targets. These methods are often combined with other attacks (e.g., phishing) to deceive users into trusting attackers.

To prevent spoofing, follow the given steps.

• Enable multi-factor authentication for your accounts. 
• Implement email authentication protocols, such as Sender Policy Framework (SPF) that will verify the authenticity of the email sender.

3. Phishing Attack

Phishing involves attackers impersonating legitimate sources through electronic means in order to coax users into providing sensitive data or clicking on malicious links. Another form of this is spear phishing. Spear phishing is a more focused form of phishing that targets specific individuals or organizations.

Follow the steps given below to prevent phishing.

• Make sure spam filters and phishing protection features are activated on your email or security software.
• Refrain from clicking on unexpected attachments or links, especially the ones from unknown emails and websites, asking for personal information.

4. Identity-Based Attacks

In identity-based strikes, cybercriminals leverage stolen or fake credentials to illicitly access target systems or data. This can include password theft, social engineering, or credential stuffing, where attackers use previously breached login details in automated attempts to access other accounts. Once inside a system, the attacker can perform malicious activities, such as data theft, tampering, or deploying malware.

Follow these steps to prevent identity-based cyber attacks.

• Avoid sharing credentials with others and use strong and unique passwords.
• Along with multi-factor authentication, regularly review activities to know about sign-in locations and devices.

5. Denial-of-Service (DoS) Attacks

DoS aims to incapacitate systems, networks, or services by flooding them, making them inaccessible. It is achieved by inundating targets with requests or data packets, leading to crashes or unresponsiveness. Distributed Denial-of-Service (DDoS) attacks involve multiple systems attacking one victim, intensifying the assault.

Follow these steps to prevent Denial-of-Service attacks.

• Use network monitoring tools to analyze and prevent traffic accordingly.
• Use DoS mitigation techniques, such as load balancers, firewalls, and intrusion prevention systems.

6. Code Injection Attacks

Code injection attacks involve inserting malicious code into a targeted system or application, usually via input fields or other data entry points. Once executed, the malicious code can compromise the system, allowing the attacker to steal data, deface web pages, or gain control of the target. Common types of code injection attacks, include SQL injection, cross-site scripting (XSS), and remote file inclusion (RFI).

Follow these steps to prevent code injection attacks.

• Make use of parameterized queries and prepared statements.
• Practice input validation exercises to ensure data is thoroughly validated before being processed.

7. Supply Chain Attacks

Supply chain attacks target software and hardware vendors, infiltrating their products or services before they reach the end user. This can include compromising source code, altering hardware components, or inserting malicious code into software updates. Supply chain attacks are particularly dangerous as they can bypass traditional security measures, giving attackers access to sensitive systems and data. The SolarWinds hack in 2020 is a prime example of a supply chain attack that had significant ramifications.

Follow these steps to prevent supply chain attacks.

• Through vendor risk management programs, evaluate security controls, certifications, and incident response capabilities of the suppliers, partners, and third-party vendors.
• Make sure you validate the authenticity of the software and codes acquired from third-party sources.

8. Insider Threats

Insider threats arise from within an organization and are perpetrated by employees, contractors, or other individuals with authorized access to sensitive information or systems. These attacks can be malicious, where the insider knowingly seeks to cause harm, or accidental, such as when an employee unwittingly exposes sensitive data or falls victim to phishing. Regardless of intent, insider threats can lead to significant damage, including data theft, system compromise, and financial loss.

Follow these steps to prevent insider threats.

• Regularly check the user activities, network, and system logs for any unauthorized access and behavior. 
• Raise awareness among employees regarding the protection of sensitive data and recognizing signs of insider threats.

9. DNS Tunneling

DNS tunneling is a technique used by attackers to bypass network security measures by encapsulating non-DNS traffic within DNS protocols. This allows them to establish a covert communication channel with their target, often used for data exfiltration or remote command and control. DNS tunneling can be difficult to detect and is often used in advanced persistent threat (APT) campaigns.

Follow these steps to prevent DNS tunneling.

• Use DNS Security Extensions to validate the authenticity of DNS responses. 
• Review DNS logs and analyze network traffic patterns regularly to identify suspicious DNS activities.

10. IoT-Based Attacks

The Internet of Things (IoT) comprises a vast array of interconnected devices, such as smart appliances, wearables, and sensors. These devices often lack robust security features, making them attractive targets for cybercriminals.
