No software application or website has 100% security. Almost all have gaps that hackers target to exploit and steal online confidential data. What are the benefits of hackers stealing data from websites or applications? If critical data is stolen, it is very detrimental and harmful for the users of the site or an application, and a company's credibility will decrease due to a loss of consumer confidence.
What is a hacker, and what are their motives for attacking a website, computer system, online software, or application? According to Wikipedia, a hacker can be defined as a person or community with specialized computer technology skills to find security holes and solve problems.
The risks are already understood about the vulnerability of a computer system, application, software, or website being hacked by irresponsible people or groups and stealing essential data to be exploited for illegal use. Software houses with reliable and experienced programmers in their fields will work carefully and thoroughly to close any security gaps as early as possible, making it difficult for hackers because of the sophisticated security system. If needed, those investors who have significant capital will work with hackers to secure a computer system and periodically conduct tests to find security gaps so that they can be fixed.
So what are some standard techniques hackers use to attack and exploit site security?
This technique usually manipulates a command that can fool the logic of a system during the login process to a site page or web administrator page. Hackers can take over or modify the associated database if the application does not validate the input data or variables from a UR correctly.
For example: ex-am-ple.com/items/iteams.php?itemid=999; DROP TABLE USERS will generate the following SQL query:
SELECT ItemName, ItemDescription
FROM Items
WHERE ItemNumber = 999;
DROP TABLE USERS
The above query instructs to delete the user data in the database table.
Prevention:
$username = mysql_real_escape_string($_POST['username']);
or
$param = mysql_real_escape_string($_GET['ID']).
XSS is a technique of hacking a site by inserting programming code, usually using javascript, VBScript, ActiveX, Flash, and other client-side languages. There are two types of XSS attacks: Persistent XSS or Stored XSS is the most damaging type of XSS. In persistent XSS, the script will be permanently stored on the target server, such as databases or message forums. And Non-persistent XSS is an attack that works by inserting code in the URL.
Prevention:
Brute Force Attacks are usually hackers using an automated program to guess the user's password repeatedly.
Prevention:
DDoS is an attack that targets websites and servers by sending fake traffic so that the server will be disrupted, causing the service to go down. DDoS attacks attempt to exhaust application resources.
Prevention:
CSRF is a web exploitation attack that makes users, without their knowledge, send a request or request to the website through the website that is being opened at that time. Usually, this attack is an exploit URL sent to an Email to obtain essential data such as passwords/login emails.
Prevention:
Vulnerabilities are hacker attacks by inserting specific files that can be malware that, when downloaded and installed, the malware will infect the computer system.
Prevention:
That is a complete description of how to secure a computer system, application, software, or website from hacker attacks that can harm investors or users. For this reason, it is crucial to choose a software house partner that has been tested and trusted to avoid the worst possibilities. Hence, investors need regular maintenance and updates to get program updates.
Therefore, before deciding to work together, it is necessary to consider several important aspects when choosing a software company.
