Are they any threats that endanger blogs? What are they and how to solve the problems? Well, after your blog or probably website has been created, your job has not been done yet. There are still so many things to do to make sure your blog is in a secure condition. Moreover, there will be so many troubles and even threats to experience.
You should know that when there is a gap appearing in your blog, the threats can simply enter. Below, there are some threats most commonly to come to your blog through the gap. Be careful yet here are the solutions.
Malicious File Execution
The first threat every blog owner must know is Malicious File Execution. It is a kind of threat where the attacker manipulates the web to run dangerous files inside the server or the connected networks.
Malicious File Execution usually happens when the web app cannot validate or filter the input received from a user before it is used to load or run the file. The condition enables the attacker to submit a path. This path refers to a malicious file located in the server or connected networks. Consequently, the executed file automatically contains dangerous code aiming at accessing and damaging sensitive data. At least, there are 2 general forms of Malicious File Execution. What are they?
- Remote File Inclusion (RFI)
The first form is the Remote File Inclusion (RFI). In this type of execution, the attacker manipulates the web to load the malicious external file from a controllable server. The file contains dangerous files such as the PHP script that is executed by the server. It enables the attacker to access the system as well as damage the data and do other attacks.
- Local File Inclusion (LFI)
Another type of Malicious File Execution is Local File Inclusion (LFI). In this threat, the attacker manipulates the web app to load the local File in the server. The files may not be intended to be executed by the app. However, by manipulating the invalidating input, the attacker tries to load those files.
If he or she is successful, the attacker can read, change, or run sensitive files. Those files include the essential ones including the configuration files or other files accessible to important data.
Both types of Malicious File Execution bring damaging effects including system takeover, access to sensitive data, virus and malware spread, data loss, and many more. That's why you must make some effort to protect your blog from this threat. First of all, it is very important to validate and filter the user's input carefully.
Second, limit user's access to the system file to prevent them from doing anything with the file as the object. Third, always activate the security system like mod_security, and don't forget to upgrade it regularly. The software must also be always protected with the latest security patch.
Injection Flaws
The second type of threat that may damage your blog or website is Injection Flaws. Injection Flaws are security threats that take advantage of cyber gaps and vulnerability by submitting codes or commands that are unintentionally needed by the input. Once the app of your blog accepts it, the trouble happens.
How can it happen? Injection Flaws or attacks often happen when the user's input is not validated or managed well before being used in the execution and evaluation processes in the system. It enables the attacker to manipulate input and submit dangerous codes in the web environment. Then, the codes are executed by the system.
There are at least 3 types of injection Flaws you need to be aware of. Here they are.
SQL Injection refers to the use of dangerous SQL code. The code is injected or submitted into the input finally received by the web. When the input is not validated well, the code is executed by the database server. It also enables the attacker to access, modify, and delete sensitive data.
XSS is a term for an action which is known also as Cross-site Scripting. This action utilizes the web vulnerability to submit and run malicious codes on the web pages. The action can be done by the users or visitors in which they submit the data and send it to the web browser without validating and encoding the content of the data.
In this attack, the attacker runs the script or a piece of the code in the target's browser. The user session can be stolen along with much information inside it. Other damages caused by the XSS Injection are the change of the content and the possibility of other attacks to come.
- Lightweight Directory Access Protocol (LDAP) Injection
The LDAP Injection may happen when the app uses LDAP as a device to connect the web or blog with the directory server. Well, just like the name, LDAP is the device to attack by the attacker. In this attack, the attacker submits special characters, known as invalid LDAP syntaxes, into the input of the app. It causes the Directory data to be stolen, changed, or deleted.
Cross-Site Request Forgery (CSRF)
Cross-site Request Forgery (CSRF) is one of the threats targeting websites, blogs, apps, and others where the attacker manipulates the users to damage the platform without their consciences. It causes any gap and vulnerability of the platform to attack it even more.
The user's browser that has logged into the unconsciously damaged web or blog automatically sends a pre-authenticated request to the web or blog. It also forces the browser to do other things only profitable for the attacker. In other words, the attack of CSRF utilizes the weakness of the web or blog where it cannot verify properly the origin of the HTTP Request that has been received.
Quite different from other threats mentioned earlier, there are 3 entities involved in this attack. They are the attacker, the user, and the blog or web. Slightly, it is even seen by the user who attacks the web. As the attacker hides behind the user's browser, it is getting more difficult to track him or her. As there is still no detailed solution to this problem, all you can do is just tighten the cybersecurity system of your blog.
