Web development depends on small businesses, banks, and many industries. From the point of creating a web application, it is important to ensure that vulnerability management mechanisms are in place as the design progresses to prevent breaches of privacy, data leaks, and financial issues.
The most dangerous network attacks are server-side attacks where data is stored and analyzed. Let’s explore the following threats for better and enhanced back-end security.
1. Injection Flaws:
Injection flaws enable a user to provide keyword-containing data that will change the behavior of the database-based queries.
How to prevent it?
To stop injection defects, it is very EASY.
The best and easiest way to check if there are no injection vulnerabilities is a comprehensive manual source code analysis to verify if requests are made by prepared statements in the database. You can also use vulnerability testing methods by Freelance Web Developer Dubai.
And you should do the following as well.
· Using ORMs (Relational Mapping Methods for Objects).
· Escape from all entries. All else should be stored in a date field except numbers.
· Isolate your data so that in that location only the things that should be accessed from a particular location are held.
· Write good software for handling errors.
2. Broken authentication:
Authentication deals with the offering credentials. It is the security frontline against unrestricted access. Poor implementation and failure to comply with security policy, however, can result in broken authentication. Broken authentication happens mostly through three patterns:
· stuffings of credentials: where the attacker has a list of valid usernames and passwords and can automate attacks to identify the correct credentials.
· Bruteforce attack: where the application allows users or administrators to have weak passwords.
· Session hijacking: where application displays session ID, URL, or after login does not rotate.
How to prevent it?
· To avoid computer attacks, introduce multi-factor authentication.
· Encourage a good password policy for the user.
· Limit logins failed.
· Use an effective hash algorithm. Consider the max password length when selecting an algorithm.
· Test the session timeout system and make sure that after logout the session token is invalidated.
3. Broken Access Control:
There is access control to ensure what is allowed to do by authenticated users. Authentication and management of sessions are the rules of basis or access control. But if those rules aren’t well set, this can lead to major problems. Also, read WordPress Vs. Medium- Which one to choose.
How to prevent it?
· Deny except public resources by default.
· Disable the display of the folder directory and make sure that there are no backup files.
· Rate limit access to the API to minimize the impact of automated attacks.
· Invalidate JWT tokens on the backend side after logout.
4. Data Exposure:
Data leakage, also known as data breaches, is a security threat that affects companies and their customers.
This happens when information such as identification or sensitive data such as credit cards or health records are not adequately protected by the request. Each minute, more than 4,000 records are broken.
How to prevent it?
As a Web Developer Dubai, the information needs protection by following:
· Encrypt sensitive data: encrypt everything for REST data.
· For transit data, be sure to use secure gateways only by implementing key-based authentication to identify information that requires extra security and restrict accessibility to just a bunch of legitimate users.
· Using up-to-date and strong algorithms to stop poor authentication algorithms.
· Have a safety plan for backup.
5. Insecure deserialization:
Serialization and deserialization are terms that are used when translating data into object format for processing or sending to another request. Serialization consists of converting data for use in object format. Deserialization is just the opposite.
Deserializer attacks can lead to denial-of-service, access control, and remote code execution attacks if there are classes that can be modified to change behavior.
How to prevent it?
· Never trust the input of users.
· Validate information: If your application is a string except, make sure that it is a string before using it.
· Use a search to make sure that data has not been altered.
· It is helpful that you send data between two trusted sources.
