The security of a virtual server is referred to as "information security," which is the process of ensuring the availability, integrity, and confidentiality of information. Accessibility involves providing access to information, while integrity ensures accuracy and completeness, and confidentiality ensures that only authorized users access information.



Different measures and degrees of protection are necessary based on the goals and tasks performed on the virtual server. Threats to information security can come from vulnerabilities in protection systems, and the necessary security measures may vary depending on the situation.

Virtual server administrators need to take responsibility for protecting data confidentiality and integrity. The use of programs with vulnerabilities may be allowed if potential threats from attackers are not significant or advisable.

The hosting company that you rent your servers from is responsible for providing security measures against equipment, infrastructure, and man-made or natural threats. It's crucial to choose the right hosting company for reliability assurance of hardware and infrastructure components. As a virtual server administrator, consider these types of threats only when they can lead to disproportionate problems or losses.

The main threats to information security include internal system failure, supporting infrastructure failure, and violations of information integrity and confidentiality. Threats to information integrity can be static or dynamic, while threats to confidentiality can be subject or service-related. To determine the most optimal protection measures, assess both the threats to information security and the potential damage based on whether it is acceptable or not.
Establish criteria for the acceptability of damage in monetary or other forms.

I believe (a sentiment commonly shared by academic instructors) that information security should be viewed as a state rather than a process. The processes of information protection and security are instrumental in achieving this state.
Although it may sound disagreeable, the expression "information security is a process" is somewhat off-putting.

All threats in the article are classified quite meticulously, and it seems to me that they can be attributed not only to the virtual servers that are mentioned at the beginning. I think this is a universal list of network security threats.
The advice not to use programs through which an attacker can harm is certainly good, but ... it is often difficult for the user to determine which program has vulnerabilities. You probably need to contact "expensive" specialists to check all the software used.

Various actions that can lead to breaches in information protection constitute threats to computer security. Therefore, threats refer to potential events, processes, or actions that can potentially harm information and computer systems. These threats are classified into two types: natural and artificial. Natural threats include naturally occurring events like hurricanes, floods, fires, among others that are beyond human control.

On the other hand, artificial threats result from humans' actions and can be either deliberate or unintentional. Unintentional threats arise from carelessness, ignorance or inattention, such as installing unnecessary programs that hinder system operations, leading to data loss. Deliberate threats, on the other hand, are created intentionally, such as intruder attacks from within or outside an organization. Such threats result in financial losses and intellectual property damage to the organization.

When it comes to information web security, there are several types of threats that can jeopardize the integrity, availability, and confidentiality of data. Some of the common types of threats include:

1. Malware: This category includes viruses, worms, Trojans, ransomware, and other malicious software designed to disrupt or access data without authorization.

2. Phishing: This is a form of social engineering where attackers trick individuals into revealing sensitive information, such as login credentials or financial details.

3. Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks: These attacks aim to overwhelm a system or network, rendering it inaccessible to legitimate users.

4. Data breaches: Unauthorized access to sensitive data, whether through exploitation of vulnerabilities or insider threats, can lead to unauthorized exposure of confidential information.

5. Man-in-the-Middle (MitM) attacks: In this type of attack, a malicious actor intercepts communication between two parties, potentially gaining access to sensitive data being transmitted.

6. SQL injection: Attackers inject malicious SQL code into input fields of a web application, exploiting vulnerabilities in the application's database to access or modify sensitive data.

7. Cross-site scripting (XSS): Attackers inject malicious scripts into web pages viewed by other users, potentially compromising the security of those users' interactions with the web application.

8. Insider threats: Employees or individuals with authorized access to systems may intentionally or unintentionally compromise data security.

9. Zero-day attacks: Exploitation of previously unknown vulnerabilities in software or hardware before a patch or fix is available.

10. Social Engineering: This involves psychological manipulation of individuals to obtain confidential information or access to systems and networks.

11. Insider Data Theft: When authorized individuals misuse their access privileges to steal or misuse sensitive data for personal gain or malicious intent.

12. Cryptojacking: In this form of attack, unauthorized cryptocurrency mining scripts are injected into websites or systems, using the processing power of unsuspecting users' devices.

13. Fileless Malware: These types of malware do not rely on traditional file-based payloads, making them harder to detect using conventional security measures.

14. Eavesdropping: Attackers intercept network communication to eavesdrop on sensitive data being transmitted between parties.

15. Credential Stuffing: Attackers use automated tools to test large sets of usernames and passwords obtained from data breaches on various websites and services to gain unauthorized access.

16. DNS Spoofing: Manipulating the Domain Name System (DNS) to redirect traffic to malicious sites, potentially exposing users to phishing attacks or malware downloads.

17. Supply Chain Attacks: Targeting the software supply chain to inject malicious code into legitimate applications or components, compromising the security of downstream users.

Understanding the diverse array of threats to information web security is essential for developing comprehensive security strategies and implementing effective countermeasures. Stay updated on evolving cyber threats and adopt proactive security practices to mitigate risks and protect sensitive data.
