Web applications security

Imagine that you live in the world without any protection. But there is a place where all information concerning you is stored together with the balance of your bank account. Everyone can access this place and change its data, pay in or pay out money from its account but also... modify other people's data.

Even in the perfect world, there will be a person who will want to steal your personal data and money. Without protection everyone has easy and fast access to each piece of information which is precious.

It is similar with websites without any security measures in the form of a firewall, anti-virus programme or web application protection. They become an easy target of hackers, greatly benefiting from the acquired data. A website which was attacked by cybercriminals incurs large losses, not only financial ones but also related to the image.

Business in the network

We frequently hear about the leakage of personal data to the network, theft and extortion of money, lack of access to the service. If a business activity is run in the Internet, ensuring data security should be a priority.

Data security is a crucial aspect for most owners of websites. It must be multi-track protection. Firstly, it is worth using basic security measures, such as firewall, anti-virus software and what is most important educating employees within cybersecurity.

Web application protection

Web applications are locations with sensitive data. Due to easy access to website applications, they become more frequently the main target of hacker attacks. They store valuable information on service users, such as personal data, passwords, credit card numbers, etc.

The lack of proper security makes the application layer vulnerable to many hazards. Other malware is also dangerous, such as viruses and worms, whose target is to find gaps in the security of an application layer, infect and steal data or use the Internet link excessively.

How to protect this layer of a website against intruders?

Easy access to key data stored in the application layer makes attacks on web applications more and more popular. The best solution guaranteeing protection is using Web Application Firewall (WAF). This is a solution which operates on the application level. It was created based on statistical formulas and reputation mechanisms whose task is to inspect HTTP enquiries.

WAF protection ensures security against breaking into the network through web applications. It provides an opportunity of creating nonstandard rules which block joint attack patterns, e.g. SQL Injection or XSS. Owing to such a solution, stealing of the content or sensitive data is much harder.

Is it worth using WAF protection?

Security systems using WAF mechanisms process lots of data. Therefore, they are able to analyse and learn the application structure, URL or cookie. The effect of such an activity is the immediate detection of new hazards and providing new rules to all the users.

WAF security applies positive selection which accepts traffic identified as permitted. Such a procedure makes traffic not recognised as permitted to be blocked.

What sector is WAF dedicated to?

Security making use of WAF will be perfect in each sector which conducts an activity in the Internet and stores sensitive data. The more information stored, the high a cyberattack risk is. The network layer protection allows for minimising and limiting a danger related to the theft of stored data and it considerably reduces the probability of cyberattack occurrence. WAF protection will be perfect in the financial, bank, power and e-commerce sectors.

The Internet application security refers to the majority of websites owners who store sensitive data. Websites which store and process personal data require the best security. Without proper protection, companies and information stored by them will be exposed to a risk of cyberattacks, theft of data and financial and image-related losses.

WAF protects, monitors and verifies traffic directed at a website what reduces a risk of data leakage.
