6 Common Types of Cyber Attacks and Their Prevention Tips

Nowadays, cyber-attacks are getting common. A cyber attack is when an individual or group of people intentionally and maliciously tries to steal the information of another individual or company. This attack can destruct the data and can put one in trouble. In the worst scenario, data gets deleted permanently. You may then have to contact data recovery professionals if you don’t have any backup.
6 Common Types of Cyber Attacks and Their Prevention Tips
To defend yourself from threats, you need to comprehend them first. You may find yourself at discomfort while learning about the risks, but, not knowing the cyber attacks and their source can be even more troublesome. So, let us learn about the six most common types of cyber-attacks along with their prevention tips.

1. Phishing 
It is a well-known and the most common type of cyber attack and involves sending fake emails that appear to be from the trusted source. The email may contain a malicious link or an attachment, and upon clicking them, you will install malware on your system. The main goal of the phishing attack is to collect sensitive information or to spread the malware. Also, phishing is the easiest way to breach the security of the company. 

Prevention tips

  • Teach all the password security rules and regulations to your users.
  • Hover over the link before clicking and check if it goes to the URL as mentioned or not. Moreover, it is suggested to open only those emails that you receive from a trusted source or from someone you know.

2. Denial-of-Service Attacks 
If you flood a website with a huge amount of traffic that it cannot handle, then you overload the server of the website, and thus, it becomes impossible for the website to serve its content to its visitors. This is what exactly happens in a Denial-of-Service attack. DoS attack hurt businesses by flooding targeted web-server with requests. This can stop regular users from connecting.

In some cases, several computers are used at the same time for the DoS attack. In such a situation, the attack is known as a Distributed Denial-of-Service Attack. This attack hurts the reputation of the website as it leads to website downtime.

Prevention tips

  • Make sure to set the protocols to stop the attack or minimise its impact.
  • Don’t rely completely on Firewalls and ISP as they cannot stop the heavy load that people in hacking use today. The three main options that you can consider for DoS protection are on-premise protection, hybrid solution and cloud-based counteraction.

3. Man-in-the-Middle (MitM)
In this form of attack, hackers insert themselves in two legitimate hosts. The session between the remote web server and your computer has a unique session ID, and it should stay private between the two parties. But, the sad part is that hackers are always trying to hack the session IDs. Once they know the session ID, they can log in as an unsuspected user and gain access to your data. Plus, they can change the message being transmitted.

Prevention tips 

  • Do use SSL certificates to enhance security.
  • Add an extra layer of protection by setting up a VPN.

4. Credential Reuse and Password Attacks 
Generally, this is the first thing that comes in the mind of users when we talk about cyber attacks and cybersecurity. And even after knowing the risk attached to using weak passwords, they don’t use strong passwords. Do not forget that hackers have several password hacking tools and techniques and can easily detect weak passwords by using different combinations. They can use your credentials to blackmail you and can harm your reputation in the society.

Prevention tips 

  • Use strong and unique passwords for every account.
  • Educate your users about phishing methods.
  • Don’t use default passwords.

5. SQL Injection
SQL stands for Structured Query Language. It is a programming language that is used to communicate with databases. Most of the servers that store crucial data for websites use SQL to manage the data in their databases. An SQL injection attacks such servers by inserting malicious code into an SQL database. For hackers, it is a really simple task, and once they have injected the code, they can read, delete, and modify your data. And if it is deleted then considerable time and money is consumed in data recovery. Furthermore, some attacks can even result in the shutdown of your database.

 Prevention tips 

  • Stick to stored procedures and prepared statements.
  • Make use of least-privilege permissions model in your database.

6. Cross-site Scripting (XSS)
In this kind of cyber attack, the hacker attacks the user of a website. It is similar to SQL injection, but in this, the site in which the code is inserted is not attacked. Instead, the infected code that the invader has injected only runs in the browser of the visitor of the website. The most common way by which hackers insert cross-site script is by embedding a link into a comment on the blog. Cross-site scripting is dangerous for a website as it can harm its reputation and can put the user’s personal information at risk. Any personal data of the user, such as credit card details can be hijacked with XSS.

Prevention tips 

  • Make sure that your users have awareness about different phishing techniques.
  • Run cross-site scripting vulnerability tests.
