Software updates are designed to fix known security vulnerabilities and improve overall performance. Similarly, system patches are designed to address known security flaws in operating systems and software applications.

Examples of companies that have suffered attacks due to outdated software include Equifax, which suffered a massive data breach in 2017 that exposed personal information of over 147.9 million customers. The breach was caused by the company’s failure to apply a critical software patch. It is important to regularly check for updates and patches to keep software and systems up-to-date. 

  1. Weak Passwords and Authentication Practices

In today’s digital age, weak passwords and authentication practices significantly threaten personal and corporate security. Cybercriminals’ methods are becoming more sophisticated, and their capacity to crack passwords has improved. 

There are many examples of attacks that succeeded due to weak passwords. One such attack is the 2014 iCloud hack, where hackers gained access to private photos of celebrities due to weak passwords. 

Creating strong passwords and authentication practices is crucial in protecting against such attacks. Here are some tips to create strong passwords and authentication practices:

  1. Utilize a combination of numbers, letters, and symbols.
  2. Avoid using common words or phrases like “password” or “123456.”
  3. Use different passwords for different accounts.
  4. Enable two-factor authentication whenever possible.
  5. Avoid using personal information, such as birth dates or names, as passwords.
  6. Frequently change the passwords, try to change it  every three months.
  7. Utilize a password manager to store and generate secure passwords.

3. Lack of Encryption and HTTPS

Encryption and HTTPS (Hypertext Transfer Protocol Secure) are essential for securing online communication and transactions. Encryption refers to transforming data into an unreadable format, while HTTPS is a secure version of HTTP that uses encryption to protect user data during transmission. 

Encryption and HTTPS are essential for ensuring the security and privacy of online transactions and communications. Encryption makes it more difficult for attackers to intercept and read sensitive information such as credit card numbers, passwords, and personal data. HTTPS helps protect users’ data from being intercepted or modified by third parties, making it safer to browse the web and perform online transactions.

4. Ignoring Security Risks in Third-Party Services

Third-party services refer to software, platforms, and other tools developed and maintained by external providers that are integrated into a company’s IT ecosystem. While these services can enhance a company’s capabilities and efficiency, they pose significant IOT security risks on various devices like sensors, gadgets et. and it that should be addressed properly

Several high-profile companies have been targeted as a result of third-party vulnerabilities. Target suffered a data breach in 2013, resulting in the thievery of 40 million credit and debit card records. Target’s third-party HVAC system’s frailty allowed attackers to access the company’s network. 

5. Lack of Access Controls

Access controls are a crucial aspect of web security, helping to prevent unauthorized access to sensitive data and resources. In the web security context, access controls refer to the mechanisms and policies put in place to regulate. The regulation of who can access what data and resources on a website or web application is checked here. These controls ensure that only authorized users can access sensitive data and resources, preventing cybercriminals and other unauthorized users from gaining access and potentially causing damage.

Some of the most significant risks and consequences of a lack of access controls include the following:

Unauthorized Access to Sensitive Data

One of the most significant risks of a lack of access controls is that unauthorized users can access sensitive data. This can include customer details, business information and financial data. Companies can face legal and regulatory penalties for failing to protect sensitive data.

Data Loss or Corruption

Another risk of a lack of access controls is that data can be lost or corrupted due to unauthorized access or accidental deletion. If users are not properly authenticated or authorized to access specific data, they may accidentally delete or modify essential files, leading to data loss or corruption.

Increased Vulnerability to Cyber Attacks

A lack of access controls can also make websites and web applications more vulnerable to cyberattacks. Without proper authentication and authorization mechanisms in place, cybercriminals can gain access to sensitive data and resources. It will allow them to launch attacks such as SQL injection, cross-site scripting (XSS), and other attacks. 

6. No Web Application Firewall (WAF) 

WAF is a security solution designed to protect web applications from various types of attacks, including SQL injection, cross-site scripting (XSS), and other attacks. It works by analyzing incoming traffic to a web application and blocking any traffic that appears to be malicious or unauthorized. Despite the importance of a WAF in web security, many businesses need to implement this critical security solution.

The lack of a WAF in web security can leave web applications vulnerable to various attacks. Without a WAF, cybercriminals can exploit vulnerabilities in web applications, gain unauthorized access to sensitive data, and disrupt business operations. In addition, a lack of a WAF can make it more difficult for businesses to comply with regulatory requirements and industry standards for data security.

To address the risks associated with the lack of a WAF, businesses should implement a WAF solution tailored to their specific needs. This solution should be designed to protect against the most common types of attacks and more advanced threats, such as zero-day exploits.

 In addition, businesses should regularly update and maintain their WAF solution to ensure that it effectively protects against emerging threats. By implementing a WAF, businesses can help ensure the security of their web applications and protect sensitive data from unauthorized access and exploitation.

7. No Security Testing

Security testing is a critical component of web security, helping to identify vulnerabilities and weaknesses in web applications before cybercriminals can exploit them. Despite the importance of security testing, many businesses neglect to conduct adequate security testing, leaving their web applications vulnerable to attacks and data breaches.

The lack of security testing in web security can have fatal consequences for firms of all sizes. With adequate security testing, businesses may be aware of critical vulnerabilities in their web applications, leaving them open to exploitation by cybercriminals. 

To address the risks associated with a lack of security testing, businesses should implement a robust security testing program designed to identify and remediate vulnerabilities in web applications. This program should include a variety of testing methods, including penetration testing, vulnerability scanning, and code reviews. It should also be conducted regularly to identify and address new vulnerabilities promptly.

Penetration testing is a popular security testing method that simulates a real-world attack on a web application. This testing method can help identify vulnerabilities in the web application that cybercriminals could exploit. 

Vulnerability scanning is another vital testing method that involves scanning the web application for known vulnerabilities and weaknesses. Code reviews involve analyzing the code of a web application for potential security issues.

In addition to implementing a robust security testing program, businesses should ensure that their web applications are often patched and updated to address any known vulnerabilities. To prevent unwanted access to critical information and resources, they should also include adequate access controls, such as authentication and authorisation mechanisms.


In conclusion, it’s important to recap the 7 deadly web security mistakes that website owners must avoid to prevent potential cyber attacks. These include weak passwords, unsecured connections, lack of updates, insufficient access controls, insecure hosting, not testing for vulnerabilities, and needing a backup plan.
