These attacks are considered one of the most common and influential forms of cyber attacks. DDoS attacks aim to flood a server or network with a large number of bogus requests, causing interruption or slow service to legitimate users. This type of attack is often used as a means to disrupt web services or to achieve political or retaliatory goals.

Network intrusions:

These attacks represent unauthorized penetration of systems or data into a network. Attackers use security vulnerabilities or social engineering techniques to access sensitive information or to carry out illegal activities within the targeted system.

Cyber ​​attacks:

These attacks target critical infrastructure of the digital society, such as electricity and communications networks and government institutions. Attackers aim to disrupt or control this infrastructure to achieve their political, economic, or social goals.

To protect ourselves and our systems from these cyber attacks, we must take effective steps to enhance digital security. This includes using advanced security technologies, such as firewalls and intrusion detection systems, regularly updating software, and enhancing users' security awareness. By working together and committing to good security practices, we can reduce the risks of cyber attacks and keep our networks and data safe.

3. Social engineering attacks

Social engineering attacks are among the most common methods used by attackers in the cyber world to infiltrate systems and steal information. These attacks are characterized by precision and cunning, as attackers manipulate the psychological and social factors of users to achieve their evil goals. Let's take a look at the most important types of these attacks and how to confront them:

Phishing:

These attacks are among the most common, in which emails or text messages are used to trick users into providing sensitive personal information, such as passwords or bank account details. This is usually done via fake links that lead to malicious websites or download malicious files onto the victim's devices.

Social engineering:

These attacks are more sophisticated, using persuasion and psychological manipulation techniques to infiltrate information systems or obtain sensitive information. These attacks can include directly contacting employees or users and persuading them to provide confidential information or perform certain actions under false pretenses.

Phone phishing attacks:

This type of attack relies on using phone calls to trick victims and extract sensitive information from them. Attackers convince victims to perform fake actions, such as updating account information or providing banking information, so sensitive information is easily obtained.

To protect ourselves and our organizations from these dangerous attacks, we must be aware of the technologies used and enhance the security awareness of employees and users. Regular training should also be provided on how to recognize social attacks and phishing and how to deal with them. With cooperation and vigilance, we can defend against these attacks and protect our sensitive data from unauthorized access.

4. Internal threats

Internal threats to information security constitute one of the biggest challenges that organizations face in the age of digitization, as they can cause the leakage of sensitive data and negatively impact the integrity of systems. Organizations must understand the origin of these threats and apply effective strategies to confront them. Here are the most prominent types of internal threats and how to address them:

Disgruntled employees:

They are considered one of the most dangerous forms of insider threats, as they use the access they have to data and systems to carry out malicious actions. The reason behind this may be revenge or a desire to cause harm to the company. Organizations must carefully screen their employees and implement strict policies and procedures to monitor and limit data protection access.

Human error:

Human error is one of the most common causes of leaks within companies, as negligence or inattention by employees can compromise data or systems.
