Most of us have heard of terms like security holes, exploits or Exploit Kit but don’t know exactly what these terms mean. In the article below, Taimienphi.vn will explain in detail for you security hole What is a Zero-day vulnerability?
What is a security hole?
1. What is a security hole?
Computer security vulnerabilities are defined as “vulnerabilities” in any software, operating system or service that cybercriminals can exploit for their purposes. Although the security flaws and bugs are completely different, both are the result of programming errors.
An error may or may not be dangerous. As for a software flaw, it must be fixed as soon as possible because web criminals can take advantage of these vulnerabilities to perform bad behaviors.
Basically cyber criminals can take advantage of the flaw to illegally access products, then through products to access various parts of the computer network including the database. Therefore, security holes must be fixed as soon as possible to prevent the exploitation of software or system services.
Some examples of security vulnerabilities are Shellshock, Heartbleed and POODLE.
Microsoft defines security vulnerabilities as follows:
“A security flaw is a weakness in a product, allowing an attacker to compromise the integrity, availability, and security of that product.”
To make it easier to imagine, you can understand that an error that must meet the following four conditions is called a security hole:
– Weaknesses in products and software: refers to any weak prostitutes that we can call collectively. As explained above, a security flaw is considered an error but an error is not necessarily a flaw. For example, additional unprotected pieces of code can be a weakness causing software bugs, application responses longer.
– Product integrity Here is the reliability. If the weakness allows an attacker to make exploits, then the product is no longer intact.
– Product availability also addresses a weakness in which an exploiter can hijack a product and prevent users from accessing the product.
– Product security refers to the protection of secure data. If an error in the system allows unauthorized people to access and collect user data, it is called a security hole.
According to Microsoft, an error that must meet the 4 criteria above will be called a security hole. A common bug can be easily created and fixed through releases and service packs. But if an error that meets the above criteria is called a security hole. In this case the information, security alerts and patches will be released.
2. What is a Zero-day flaw?
It is understandable that the Zero-day vulnerability is a vulnerability that has not been previously known, exploited or attacked. The nature of these vulnerabilities is called Zero-day because the developers do not have time to fix and no patches are released to patch the vulnerability.
Using the Enhanced Mitigation Experience Toolkit on Windows is the best solution to protect your system from Zero-day attacks.
3. Solutions to protect the system from security holes
The best way to protect the system from security holes is to install OS updates and security patches as soon as possible. Also make sure to regularly update the latest software versions, applications that you have installed on your computer.
If you install and use Adobe Flash Player and Java on your computer, users are recommended to install the latest updates as soon as possible, which are the most vulnerable and have the most security holes. .
Also make sure you have installed and used Internet security software. Most of these software are equipped with Vulnerability Scan to scan, find and remove security holes on the operating system and software installed on your device.
Some of the best software and Internet security tools for Windows such as Secunia Personal Software Inspector, SecPod Saner Free, Microsoft Baseline Security Analyzer, Protector Plus Windows Vulnerability Scanner, Malwarebytes Anti-Exploit Tool and ExploitShield.
These tools scan your computer for operating system vulnerabilities and unprotected program code, detect and update outdated software and plug-ins to protect your computer from malicious programs. malicious attack.
