There are many threats that we can suffer when surfing the Internet. There are many types of attacks, varieties of malware, techniques that hackers use … All this can affect us as home users, put a company or organization at risk, and affect web pages and applications. Website servers can suffer many types of attacks. We are going to explain which are the main ones that can jeopardize proper operation and safety.
Attacks that can affect web servers
A web server manages all the content on a site and allows end-users to view the content. If it does not work well, the visitor could not enter the page or see everything correctly. In case that server has suffered a security attack, not only would it not work well, but it could even be a risk for visitors. They could be used to steal data, break passwords, denial of services attacks …
Cross-Site Request
We can translate it into Spanish as cross-site request forgery, also known as one-click or session attack and abbreviated as CSRF (“sea-surf”) or XSRF. It is a malicious website exploit through which unauthorized commands are transmitted from a user that the website trusts. Unlike cross-site scripting (XSS), which uses a user’s trust in a particular site, CSRF exploits a site’s trust in a user’s browser.
In this way, the attacker can act on behalf of the victim. It is basically as if that user was executing it. It is one of the most dangerous attacks due to the consequences it could have for the victim.
SQL injection
This attack is one of the most popular in web applications. Hackers will base themselves on a vulnerability, as could happen in the database layer of the web application. That code could compromise that tool and leak confidential data, information, etc.
Logically, this will cause the program to work incorrectly. At the end of the day, what the attacker does with SQL injection is modify the code that has already been previously programmed. You are going to alter the primary function it has.
Cookie poisoning attack
Cookie poisoning attacks involve modifying the contents of a cookie (personal information stored on the victim’s computer) to bypass security mechanisms. By using cookie poisoning attacks, attackers can obtain unauthorized details about another user and steal their identity.
With cookie poisoning, therefore, the attacker could obtain confidential information, such as financial data. This can put the privacy of the user at risk.
Theft of cookies
Cookie theft is a type of attack that is performed using client-side scripts such as JavaScript. When the user clicks on a link, the hand will search the cookie stored in the computer’s memory for all active cookies and send them to the hacker carrying out that attack.
Keep in mind that cookies are an essential element. They can store information about our equipment, the programs we use, personal data … They have the great value on the net.
On the other hand, the Internet provider where the website is hosted is also significant since, in addition to the security of the web application, the safety of the platform that supports it must be reviewed by Cyberg Reviews.
