Top 7 Cybersecurity Threats and Vulnerabilities

Internet usage continues to grow, and the risk of falling into prey is also increasing. Cyber ​​security attack..is expected Cybercrime will cost the world US $ 10.5 trillion annually by 2025, A number that should be enough to warn us of imminent ruin. But the positive side is that organizations and businesses are taking steps to strengthen their security defenses.

But the first step to resist Cyber ​​security attack I understand many things Cyber ​​security threat A vulnerability that compromises the security and integrity of sensitive data.

What are cybersecurity threats and vulnerabilities?

Understand cyber security threats and Vulnerability It’s important to develop effective and strong cyber security policies and keep your data assets safe from everything else. Cyber ​​security attack..

Cybersecurity threats are external hazards that can steal or damage data, cause confusion, or cause general harm. A threat is a malicious, deliberate attack by an individual, group of individuals, or an organization that steals, damages, or destroys IT assets, intellectual property, or other sensitive data. Unauthorized access to another organization’s or personal’s network / system.General example of Cyber ​​security threat It includes phishing, malware, and even rogue employees.

Cybersecurity vulnerabilities, on the other hand, are weaknesses or flaws in computer systems or networks that can lead to security breaches if compromised by cybersecurity threats. The vulnerabilities may be physical vulnerabilities such as exposing network devices, or non-physical vulnerabilities such as operating systems that are vulnerable to virus attacks without the latest security patches. therefore, Cyber ​​security vulnerabilities It exists in the network or in the computer system itself.

Top 7 Cybersecurity Threats and Vulnerabilities

Cybersecurity professionals need a deep understanding of the following cybersecurity threats and vulnerabilities:

1. Malware

Malware is malicious software. When the user clicks on a malicious link or attachment, it becomes active and installs malicious software. When activated, malware installs additional harmful software, blocks access to critical network components, interferes with individual parts, or secretly sends data from hard drives. There is a possibility.

The goal of most malware programs is to access and copy sensitive data. Advanced malware programs can autonomously replicate and send data to specific ports or servers that attackers can use to steal information. Common symptoms of malware-infected systems are slowdowns, random reboots, sending emails without user interaction, or the start of an unknown process. One of the most common malware is malicious programs, which are ransomware that can lock users out of computer applications or entire computer systems until the ransom is paid. Worms, viruses, and Trojan horses are better known malware.

2. Phishing

Phishing is one of the most common Cyber ​​security threat It is based on a social engineering scheme. Phishing attacks include cybercriminals who send malicious emails that appear to come from legitimate sources. The recipient is then fooled into clicking on a malicious link in the email or performing internal instructions such as providing bank account credentials.

The purpose of phishing scams is to install malicious software or steal sensitive data such as login credentials and credit card details. The most critical vulnerabilities targeted by phishing attackers are weak email security structures. A variation of traditional fishing is spearfishing. This allows an attacker to target a specific group, individual, or organization instead of sending a large number of emails.

3. Denial of service (DoS) attack

Denial of service (DoS) attacks are intended to overwhelm a system, network, or server with heavy traffic and prevent users from accessing critical applications. DoS attacks ultimately paralyze a network or system in one of the following ways:

  • Forwards an excessive amount of false traffic to the target network address (buffer overflow).
  • It disrupts data routing to the target network and causes a crash (teardrop attack).
  • Initiates multiple fictitious connection requests to the target server (SYN flood).

DoS attacks are aimed at degrading the quality of service and causing massive downtime, rather than damaging or stealing data. When a DoS attack affects multiple devices in your network, it is called a distributed denial of service (DDoS) attack. As a result, DDoS attacks are more likely to be damaged.

4. Man-in-the-middle (MitM) attack

A man-in-the-middle (MitM) attack occurs when a cybercriminal puts himself in a two-way communication between a user and an application. This allows an attacker to disrupt traffic and interpret the communication. As a result, an attacker can filter and steal sensitive data such as account details, login credentials, and credit card numbers. The attacker spies or imitates one of the parties to pretend to be a regular exchange of information.

MitM attacks can also cause the installation of viruses, worms, or other malware. MitM attacks are common when using unsecured public Wi-Fi networks. There are several ways to perform a MitM attack:

  • Wi-Fi hacking
  • SSL hacking
  • HTTPS spoofing
  • DNS spoofing
  • IP spoofing

5. SQL injection attack

Structured query language or SQL injection is a type of cybersecurity threat that allows an attacker to upload malicious code to a server that uses SQL. Such code controls the database server behind the web application.

Once infected, an attacker could exploit a SQL injection vulnerability to evade application security measures and evade authentication and authorization of a web application or web page to retrieve the entire content of a SQL database. In addition, an attacker can view, delete, or modify the data stored in the SQL database. SQL injection attacks typically affect web apps and websites that use SQL databases. Such attacks can not only tamper with individual machines, but also affect the entire network.

6. Superuser account

One of the basic principles for mitigating software vulnerabilities is to limit user access. The less resources a user has access to, the less likely they are to be harmed if their user account is compromised.

Superuser accounts are often used for administrative purposes and can turn into network vulnerabilities. However, in most cases, organizations miss the danger and cannot manage user access account privileges. As a result, almost every user in the network has so-called administrator-level or “superuser” access. In addition, certain computer security configurations allow unprivileged users unlimited access to administrator-level user accounts. Therefore, such a “superuser” can modify, create, delete files, copy information, or install any software. And if a cybercriminal accesses such an account, the impact can be disastrous for the organization.

7. Unpatched or outdated software

A common cybersecurity threat is to ignore regular software patching and updates. There are many new and sophisticated threats that occur every day, but many exploit old security vulnerabilities. Therefore, with so many threats targeting a small number of selected vulnerabilities, one of the biggest mistakes organizations and businesses make is the inability to patch software vulnerabilities when they are discovered. is.

Installing updates and continuously applying new patches can be tedious and time-consuming, but it certainly saves individuals, businesses, or organizations from a significant loss of time and money. Failure to install timely updates and apply new patches leaves your system or network vulnerable to defects fixed by software and hardware vendors.

What are the five threats to cybersecurity?

Some of the biggest cybersecurity threats are:
1. Malware
2. Phishing
3. SQL injection
4. Denial of service (DoS) attack
5. Man-in-the-middle attack

What are cybersecurity vulnerabilities?

Cybersecurity vulnerabilities are weaknesses or flaws in an organization’s system processes, internal controls, or information systems that cybercriminals can exploit to launch cyberattacks. Vulnerabilities are different from threats. The former exists from the beginning because it has not been introduced into the system.

How do you identify cybersecurity risks?

Here are the steps you take to identify, assess, and mitigate cybersecurity risks:
