The web resource does not have an SSL certificate
Posted: Sun Feb 02, 2025 6:37 am
This refers to a special digital signature that confirms that the secure HTTPS encryption protocol is used to transfer any data. If there is a certificate, there will be a lock icon in the search bar next to the link.
You can purchase both paid and free SSL certificates from special certification centers. The former have a longer validity period, and in this case, compensation for financial losses is guaranteed if an information leak does occur.
Using passwords in clear text
It is better to encrypt passwords, and it is loadrunner protocol list preferable to use a special hashing algorithm for this (for example, the SHA digit). In this case, only encrypted user data is allowed to be checked at the time of authentication.
Mandatory conditions for creating passwords will also help reduce vulnerability. Among them may be the requirement to use a minimum specified number of characters of different registers, letters and numbers, etc. A password like 12345 is a very dubious protection. As for the length, a combination of 20 characters is considered reliable, and less than 8 is not allowed.
What are the types of website vulnerabilities?
Probability of hacking through injections
This means that the user enters unverified data into the interpreter, and it ends up on the site. This can happen as a result of any visitor's actions. Most often, injections occur with SQL, LDAP, XXE, OS codes.
SQL injections are the most common. They allow hackers to penetrate databases and not only use classified information, but can even adjust the indicators themselves. What are the reasons for such vulnerabilities? This happens if the interpreter receives data without mandatory control sequences or commands (in SQL, these are, for example, quotes).
Complications at the authentication and session management stage
There are many applications that identify the user before starting to work with them. Often, there are failures in the functionality, and then the accounts of visitors end up in the hands of fraudsters without entering passwords. Hackers have learned to intercept and use (both once and repeatedly) keys and tokens by which the system recognizes its clients.
XSS (Cross-Site Scripting) Website Vulnerability
This is not the most serious type of danger for the server, it is more of a threat to the user's browser. Cross-Site Scripting is essentially injections that work through JavaScript. A hacker enters JS code into some field, and the user's search engine considers it correct (because it seems to have come from the site) and accepts it for execution. To protect yourself from such injections, it is recommended to use functions like htmlspecialchars (or similar), which allow you to escape the special characters used.
Loss of control over access to a resource
Even on serious well-known engines, it happens that data not intended for users turns out to be open (due to administrative oversights). For example, situations with files in the root of the resource address. A file like wp-config.php (that is, with the php extension) will not open through database access passwords. The browser will be able to open only a backup copy with the .swp extension, which will be formed if the original type of extension is converted to Vim. Another version of the access control problem is failures in the application code, due to which unauthorized visitors have access to classified information.
