Security is one of the most important issues in the design and creation of applications, especially in the case of systems that operate on so-called confidential data such as personal data, addresses, bank account numbers, passwords, etc. This article is about the security of Internet systems and will describe the problems associated with widely understood network application security.

 

The topic of security is very broad, so below are only general characteristics of the problems that every programmer and designer should consider.

 

Introduction

The overall level of security of a web application is made up of many factors, and it is difficult to clearly determine which one is most important. It is commonly said that the level of security of a system is as high as the least secure element in that system.

 

Therefore, it is important to protect all parts of the application as accurately as possible and try to analyze as many actions as possible that could cause security threats, and try to counter them if possible. It should also be borne in mind that in the vast majority of cases, threats are caused by people, knowingly or unknowingly. Most application security vulnerabilities arise from the ignorance of an obvious danger, rather than from any special hacking technique used by an attacker. Although you should strive to ensure maximum system security, it is impossible to achieve complete security, especially in network applications accessible over the Internet.

 

Confidentiality

 

Data is a key element of dynamic websites. Some of them are trivial and require no special protection. However, there are also data such as names and addresses, passwords, insurances, credit card numbers, phone numbers, etc. This is so-called personal data that should not become publicly available. Their value lies in the fact that they help establish the unique identity of their owner. Such data should be protected and the application should only disclose it in appropriate situations. This means that you must ensure that while the application is running, this information will not be revealed in any unplanned and accidental way. In addition, if an application is transmitting sensitive data over a network, appropriate measures must be taken to ensure the security of the information during transmission, such as encryption.

 

Data integrity, verification and encryption

In data-driven internet applications, data integrity is paramount. This means that the data will be validated every time it enters the system, and that there are ways to validate it. The programmer writing the application must always assume that the user will enter incorrect data.

Also, make sure the data is not altered or damaged. A good way to protect your data is to encrypt it.

 

Authentication

 

Authentication is the process of determining if a person is who they say they are. Nothing can happen in an application until the system is sure who it is dealing with.

Authentication is often done using a username and password. Knowledge of this data is considered as confirmation of the user's identity. Each user is initially registered by providing some password assigned to him. The user must know this password on subsequent visits. The system often imposes conditions for creating a password on users (for example, a certain number of characters, additional numbers or symbols, etc.), thereby ensuring its proper security. However, the main problem with passwords is that people forget them.

 

Authorization and access control

 

The next step is to authenticate the user. Authorization is the process of granting users permission to perform certain actions or access certain data. The fact that someone is logged into an application does not mean that they should be allowed to use all of its features. Always specify what capabilities the authenticated user will have.

 

Once the user is authenticated, you need to keep track of what they are doing and record those that are critical to the security of the system. Thanks to this, if something bad happens, you can get information about what happened and who can be responsible for it.

 

Examples of events related to system security:

 

  • successful and unsuccessful login attempts;
  • logging out of the user's system;
  • attempts to log in with an incorrect password;
  • operations of creating, updating and deleting a user account;
  • starting and stopping the server;
  • unexpected system events;
  • Change Password;
  • performing actions that require large permissions, etc.
