Website security vulnerabilities that you may not know about

Nowadays website security has become one of the most important issues for businesses and individuals who own websites. Although there are many security measures in place, there are still vulnerabilities that you may not be aware of. This article will delve into the analysis of common website security vulnerabilities and how to recognize and prevent them.

What are security vulnerabilities?

Vulnerability is a popular concept in the field of information security. There are many different definitions of security vulnerabilities, but they all have in common that they refer to a weakness (technical or non-technical) of a protocol, software, hardware or information system.

These vulnerabilities can appear for many reasons. These include programming errors, unsafe system design, or lack of necessary security measures. Detecting and remediating security vulnerabilities is an important part of risk management and information protection.

Some definitions of security vulnerabilities from authority sources

According to the National Institute of Standards and Technology (NIST), a security vulnerability is a weakness in a system security process, information system, internal control or implementation that can be exploited by an actor. harm. According to ISO 27005, a security vulnerability is understood as a weakness of one or a group of assets that can be exploited by one or more cyber threats.

According to ENISA, the existence of a weakness, design or implementation error can lead to an unexpected incident that compromises the security of the computer system, application, network or associated protocol . According to ISACA, a vulnerability is considered a weakness in design, implementation, operations or internal control.

Distinguish between security vulnerabilities and security risks

A security vulnerability is a weakness that exists in a system, software, hardware or network configuration. Attackers can exploit these weaknesses to infiltrate, steal data or sabotage the system.

Security risk is the possibility of a cybersecurity breach event occurring, leading to loss for an organization or individual. Security risks stem from many factors, including:

  • Security hole
  • Security threats, such as viruses, malware, cyber attacks
  • Human factors, such as lack of knowledge about network security, erroneous operations

Common security vulnerabilities

Some common security vulnerabilities include: SQL Injection, Cross-Site Scripting (XSS), and Cross-Site Request Forgery (CSRF). These vulnerabilities can lead to unauthorized access to data, alteration or deletion of data. Or perform unwanted actions in the web application.

To protect the system, it is necessary to apply security measures. Such as checking input from users, using reasonable CORS policies, and validating CSRF tokens.

Causes of security holes

The causes of security holes are often related to many different factors. Some of these include shortcomings in the software design and programming process. Using open source components that are not strictly controlled, or not updating security patches in a timely manner.

In addition, the increasing complexity of information technology systems also increases the possibility of vulnerabilities. To mitigate risk, investment in comprehensive cybersecurity measures and employee training on cybersecurity risks is required.

Information exploited from security holes

Information exploited from security holes often includes: login name, password, personal information such as email address, phone number, home address, etc. There is also financial information such as credit card numbers, bank account numbers, and in some cases, other sensitive data. Protecting personal and financial information is extremely important to avoid unnecessary risks.

Vulnerability management methods

Below are commonly used vulnerability security methods today:

Google Hacking

Google Hacking is the use of specific keywords in Google’s search engine to find potentially sensitive information on the internet that is not properly protected. This is a technique used by security experts to detect security vulnerabilities in web systems and applications.

By entering special search queries, users can find websites and documents that are not normally easily accessible. This method requires a deep understanding of how Google works and how information is indexed on the internet. It also requires an understanding of cybersecurity to be able to distinguish between useful information and irrelevant or harmful information.

Penetration testing

Vulnerability management method by Penetration Testing is an important information security assessment process. The purpose is to help organizations detect and promptly fix weaknesses in their systems. Thereby, minimizing the risk of external attacks and protecting data and information assets.
Applying penetration testing helps organizations not only comply with international information security standards such as ISO/IEC 27001. In addition, it also raises cybersecurity awareness throughout the entire organization. This is an important part of building a comprehensive information security strategy.

Vulnerability scanning

This system vulnerability management method uses software tools to automatically detect and assess security vulnerabilities in networks, applications, and databases.

Vulnerability scanning helps network administrators have an overview of the security status of the information system. From there, we can identify weaknesses that need to be prioritized to overcome. The scanning process helps search for known vulnerabilities through public vulnerability databases such as CVE. It is also possible to discover new, unpublished vulnerabilities.

In the digital age, website security is an important factor that cannot be ignored. Security vulnerabilities can appear without our knowledge, causing serious consequences. To ensure information security, regular updates, checks and application of strict security measures are necessary. Always be alert and ready to deal with potential risks to protect your data and that of your users.
