With the availably of internet and advanced technology in the current society, web application security is a key concern for developers as well as business people. This prospect stems from rising Internet threats. Hence, the necessity for protection of Web applications is more so than before. For any web project – from an individual weblog to a corporate software application, security is a major concern. It plays some of the roles of reducing the risks related to leakage of data and other risks. Such threats therefore include the following; customer trust is eroded and financial loss may be incurred.
Here we will also look at the reasons as to why web application security is crucial, some of the major threats. We will also cover some tips on the best way to protect your web application from a cyber attack. If you reach the end of this article, you will have a clear foresight into web application security and what measures to put in place.
What are the Consequences of Compromised Web Application Security?
Web application security is a crucial component in the protection of your clients’ information. Thanks to the development of the internet, at the present, all types of companies have their web platforms, ranging from banking to retail. Sadly, this has also made web applications to become favorites for hackers as they exploit their dependency to cause havoc.
The following are the possible consequences in case of a breach in the web application’s security:
- Loss of sensitive information
- Losses in customer morale and generalized disrespect of your company’s image.
- The cost of time out or having to pay for ransom.
- Legal consequences for the lack of a sufficient protection of users’ data
This is why implementing strong web application security measures is essential. It can significantly help in preventing these negative outcomes. Now let’s turn to examples of how to strengthen the protection of your mobile app.
An inventory of commonly experienced WEB APP SEC threats
First, to explain best practices let’s go through the most popular security hazards that your application is likely to encounter. Understanding these types of vulnerabilities will help you to allocate your web application security more efficiently.
1. SQL Injection (SQLi)
SQL injection means that an intruder enters in your database unauthorized SQL requests. Such kind of attack can lead to disclosure or alteration of some important data. There are several recommendations to strengthen your web application security against SQL injection. These include sanitizing user input and using prepared statements.
2. Cross-Site Scripting (XSS)
Cross site scripting attacks trick a trusted website to display and execute on the user’s browser malicious scripts. This can result into session hijack or distribution of other malicious programs. To control cross scripting do sanitize the inputs, and enforce the use of Content Security Policies (CSPs).
3. Cross-Site Request Forgery (CSRF)
CSRF attacks force the victims to take certain actions on your application and mostly they do this against their will. It is recommended to use anti-CSRF tokens to improve your web application’s security. Additionally, secure cookies can further enhance its resistance to such attacks.
4. Broken Authentication
Inadequate authentications provide methods that make it easy for an intruder to access the restricted sections of your application. . Using and enforcing strong passwords, along with adding two-factor authentication (2FA), are crucial for enhancing web application security. Managing secure sessions is another important factor that further strengthens protection.

Best Practices for Web Application Security
1. Implement Strong Password Policies
This can be done by ensuring that proper password policies are put in place; this is one of the simplest ways of enhancing security of a web application. Remind your users to establish difficult passwords by a combination of the uppercase letters, lowercase letters, numbers, and symbols. Additional suggestions include avoiding the use of popular or easily predictable passwords. It’s also important to implement password expiration policies and lockout provisions in case of multiple failed login attempts.
2. All communication that is sensitive in nature should be encrypted using the https.
It is part of the basics of internet application safety that the communication among the patron and the server should be secure. Make sure that your website online is the use of HTTPS so that it will guard statistics going between the server and the consumer. While using SSL/TLS certificates, you protect such crucial data as login and payment information but also enhance your site’s trustworthiness.
3. String Manipulations: Data Validation and Data Sanitization
User input arguably represents the main cause through which numerous web based threats can gain access. The use of forms in web applications poses a challenge in validating and sanitizing all user inputs. This highlights the need to pay close attention to web application security. It might be wise to always scrutinize user input and sanitize it before using it. This step can help to avoid such threats as SQL injections, XSS attacks, as well as all the other risks that can be associated with input manipulation.
Securing Authentication and Sessions for Web Application Security
In general, authentication is a process that aims at confirming the identity of a user that operates or tries to gain access to a certain system. To increase the web application security, proper solutions should be used for authentication of the applications. Here are a few ways to do that:Here are a few ways to do that:
1. Use Multi-Factor Authentication (MFA)
Further enhancing security by adopting multi factor authentication can go along way in minimizing such incidences. MFA in its simplest form, makes users identify themselves via two or more verification factors including password and the temporary code sent to their phone number.
2. Implement Secure Session Management for Web Application Security
To ensure web application security after authentication, secure sessions are very important to be implemented. In general, for session management, use secure cookies only; and apply cookies to HttpOnly as well as Secure. The possible solutions include: changing the IDs of the sessions frequently and the use of a timeout to deal with session hijacking threats.
Web Application Security against Data Leakers
1. Encrypt Sensitive Data for Web Application Security
In order to build a solid wall of security in the realm of web applications one must consider data encryption in transit as well as in storage. For save-point and user information like passwords, passwords hashing algorithms like bcrypt or Argon2 should be used. We already know that one should never store plain-text passwords in the database.
2. Conduct Routine Security and Vulnerability Study and Testing
Every safety plan should therefore entail testing of the application for weaknesses from time to time. Security audit and penetration testing reveal areas of your web application that is weak and most likely to be exploited by attackers. To that end, dorking can also improve the safety of applications. You can sue tools like OWASP ZAP for this purpose. Otherwise, there are a set of tools from security experts that you can use to solve the problem.
3. Adopt the Least Privilege Access Control
The principle of minimum authorization means that as a user of a particular system, you only be granted the amount of authorization required to use that system. The effect of curtailage on rights of access also minimize loss during violation. This practice is useful in enhancing the over security of web applications in general.

Hiding behind the effectiveness of Web Application Firewalls (WAF)
A Web Application Firewall (WAF) can be explained as that layer between your web application and the internet that filters out malicious traffic. FWs can block several types of attacks such as; SQL injections, XSS, and CSRF. Conducting a WAF as an added security layer mitigates risks to one’s application.
This is the last layer where all activities and responses to threats for Web application security are supervised.
Despite the implemented web application security measures the attack is always round the corner. It also enables you to identify suspicious activity before they progress to dangerous levels. Having IDS and automated logging systems in place will help you navigate threats, even if it has negative ones impact on your people.
Probably the most important advantage of having an incident response plan is that it reduces the level of losses, and ensures a swift and efficient recovery. Ideally it should be as part of the overall company strategy. It should include how to identify a breach; prevent it from proliferating; and recommence business operations.
Keeping Your Web Application Secure
