Cyber attacks have become an important security threat in cyberspace. Due to increasing dependency on technology in daily life, it became essential to maintain cyber security against cyber attacks. A cyber attack is an attempt to breach or damage a computer system, network, or digital data.
In this blog, we will discuss the different types of cyberattacks and how to prevent them.
What is a Cyber Attack?
A cyberattack is a conscious effort to harm, steal, expose, modify, disable, or destroy data through unauthorized access to cyberspace.
The main aim of cyber attacks is to damage individuals entity, corporations, government agencies, and essential facilities. Their outcomes can foster massive negative impacts, including financial damages, harm to reputation, breaches of privacy, physical injuries, and many more.
Types of Cyber Attacks
There are various types of cyber-attacks in the digital world. Some of the most common types of cyber-attacks are given below:
1. Malware
Malware, or malicious software, is designed to penetrate systems and cause harm. There are various types of malicious software like viruses, computer worms, Trojans, ransomware, spyware, and adware. In these attacks, malicious code is installed or executed on the target system and steals sensitive information, disrupts system operations, or gains unauthorized access. By using antivirus and regular system updates we can defend against malware attacks.
2. Phishing
Phishing attacks use manipulative methods to mislead individuals into revealing sensitive information, such as passwords, credit card details, bank account details, social security numbers, and so on. We can prevent phishing attacks by educating individuals about how to identify phishing attempts and exercising.
3. Spoofing
Spoofing is a cyberattack where a hacker replicates a credible entity, such as a website, email address, or IP address, to mislead victims. The goal is to steal sensitive information, gain unauthorized access, or spread malware. There are various spoofing methods including email spoofing, IP spoofing, and website spoofing, posing serious security risks. We can prevent spoofing by using email authentication protocols, and Multi-factor authentication.
4. Trojan
A Trojan virus attack is a type of malware that downloads into a computer virus is a type of malware that downloads onto a computer concealed as an authorized program. In these attacks, hackers use social engineering techniques to hide malicious code in authorized software and gain access to the target system.
5. Ransomware
A ransomware attack is a type of malicious software that involves hijacking of data of an individual or organization and demands a ransom(money) in exchange for its release. Such types of attacks can be avoided by the use of data backups, strong security practices, and awareness of suspicious links.
6. Password Attacks
In this type of attack, hackers try to guess possible combinations of passwords or use software like keylogging to hack the system.
7. DDoS Attacks
A DDoS or Distributed Denial of Service attack overwhelms a target network by flooding excessive traffic from multiple sources. As an outcome, the whole network operation does not work proper manner, data loss, and websites unavailable to authorized users.
8. IoT Attacks
IoT attacks target all wearable devices like smartphones, smart watches, and smart devices, to steal information of users and unauthorized access.
9. Crytojacking
Crytojacking is also a cyber attack where attackers use a user’s device to hack cryptocurrency without the knowledge of the victim.
10. Drive-by download
In this type of attack, malicious software is automatically installed and run on the target system with user consent.
11. Man-in-the-Middle (MitM) Attacks
In this attack, when communication occurs between two parties, the attacker inhibits the data communication process by manipulating the data, or eavesdropping.
12. SQL Injection Attacks
SQL injection attacks target web applications that rely on a database to store and retrieve data. By injecting malicious SQL queries into input fields, attackers exploit the application’s code vulnerabilities to gain unauthorized access to the underlying database or manipulate the data within it.
13. Zero-Day Exploits
Zero-day exploits refer to software or system vulnerabilities unknown to the software vendor or developers. Cybercriminals discover and exploit these vulnerabilities before a patch or fix is available, giving defenders no time to respond.
14. Social Engineering Attacks
A social engineering attack plays with user psychology and exploits their privacy and information.
15. Insider Threats
Insider threats state the involvement of individuals within a business organization who misuse their basic access privileges and also intentionally cause harm to the respective organization’s systems, data, or reputation.
16. Session hijacking
Session hijacking is a type of man-in-the-middle attack. The attacker takes over a session between a client and the server. The computer being used in the attack substitutes its Internet Protocol (IP) address for that of the client computer, and the server continues the session without suspecting it is communicating with the attacker instead of the client.
How to Protect Yourself Against Cyber Attacks?
To preventing various cyber-attacks, requires strong passwords, multi-factor authentication, regular software updates, employee cyber education and awareness training, network security measures, and recovery planning. Below are the methods of cyber attack prevention:
Regular Software Updates and Patches
Regular software updates improve cybersecurity and reduce cyberattacks. Hackers are trying to exploit vulnerabilities in software and take gain for unauthorized access. Regular updates avoid malicious activities, unauthorized access, and attacks.
Install a Firewall
A firewall must be deployed to prevent cyber attacks and unauthorized access. Firewalls ensure that only authorized traffic passes into and out of each connected network. It is a network connectivity device, a combination of hardware and software components that implements the network security policy.
Back up data
By using a backup, we can recover lost data. Backing up data involves creating copies of important files or systems to protect against loss. These copies are stored separately, ensuring recovery in case of device failure, accidental deletion, or data corruption.
Encrypt data
Encryption is an important method to secure data. In this method data in converted into an unreadable form. So that attacker can not read the original message or data.
Strong Passwords and Multi-Factor Authentication
Strong passwords and multi-factor authentication are important data prevention methods. A strong password must be a rare combination of special characters, symbols, and upper and lower case letters. Whereas MFA requires users to offer two or more information of evidence to verify their identities, such as a password combined with a fingerprint scanning solution, a code sent to a smartphone device, or a security token.
Employee Education and Awareness
Every organization must provide cybersecurity training to their employees in regular time periods. Cybersecurity awareness training programs must cover how to prevent cyberattacks, how to identify cyberattacks, and how to report them. These regular awareness campaigns and training programs definitely decrease cyber-attacks.
Conclusion
As we know, the digital world is increasing, and we are depending on technologies; the threat of cyber-attacks is a reality. So knowledge of cybersecurity awareness is compulsory for everyone. This will help to avoid cyber-attacks. In this blog, we covered various types of cyberattacks and their prevention.
