What are Cyber Security Threats and Vulnerabilities?

Cyber security threats are any threat that targets our electronic infrastructure and computer networks. It can include anything from viruses and malware to cyber-attacks and system vulnerabilities. To protect our online assets and understand what a threat in cyber security is, it is essential to understand the different types of cyber security threats and vulnerabilities.

One of the most recurrent cyber security threats is malware. It is a type of software that is specifically designed to damage or disable computers. It can come from a virus, Trojan horse, worm, or spyware. Malware can be used to steal compromising information, delete important files, or even take control of a victim’s computer. Another common type of threat is a cyber-attack. This is when a hacker attempts to gain unauthorized access to a computer system or network to steal data or disrupt operations. Cyber-attacks can be very sophisticated and targeted, or they can be relatively simple and indiscriminate.

On the other hand, system vulnerabilities are a type of threat that cybercriminals can exploit. These are weaknesses in a computer system or network that can be used to gain unauthorized access or to cause damage. Common vulnerabilities include unpatched software, weak passwords, and open ports.

To protect against these threats, it is vital to have a solid cyber security strategy in place. It should include firewalls, intrusion detection and prevention systems, and encryption. It is also essential to keep systems and software up-to-date and to educate users on best practices for security.

The Evolution of Cyber Security

Cyber security has changed dramatically recently, with many sophisticated threats targeting businesses and individuals alike. In response, the security industry has evolved to meet these challenges, with new technologies and approaches designed to keep pace with the evolving threat landscape.

A significant change in the cyber security landscape has been the growth of the IoT (Internet of Things). The IoT refers to the growing number of devices connected to the internet, including everything from smart TVs to connected cars. This increase in connected devices has created new opportunities for attackers, who can exploit vulnerabilities in these devices to gain access to sensitive data. In response, the security industry has developed new IoT security solutions, such as IoT firewalls and security appliances.

The cyber security landscape is constantly changing, and the security industry must continually evolve to stay ahead of the latest threats. By understanding the latest trends and developments in the security industry, businesses and individuals can ensure that they are better protected against the ever-changing threat landscape.

Types of Cyber Security Threats with Examples

There are many different types of attacks in cyber security, and they can come from various sources. Most common include viruses, malware, phishing scams, and Denial of Service (DoS) attacks. Cyber security threats can have multiple impacts, from causing financial damage to compromising confidential information. They can also lead to a loss of productivity, as systems are unavailable or disrupted. In addition, cyber security threats can pose a physical safety risk in some cases if they allow attackers to take control of critical infrastructure or devices. 

The top 10 cyber security threats with examples are as follows. 

1. Malware

Malware is a cyber security threat that can come in many forms, such as viruses, worms, Trojan horses, and spyware. Malware can damage or disable a computer, steal information, or gain access to confidential data. In some cases, malware can even be used to take control of a victim's computer. There are many different types of malware attacks, and each one can have various consequences.

1. Trojan virus: It is a type of malware that tricks users into thinking they are downloading a legitimate file when the file is malicious. Once the file is executed, the Trojan virus can give the attacker access to the victim's system and allow them to perform malicious actions, such as stealing data or installing more malware. 
2. Worm: It is a type of malware designed to spread itself by replicating itself and sending it to other systems. Worms can cause a lot of damage because they can spread quickly and use up a lot of resources, which can cause systems to crash. 
3. Ransomware: It is another type of malware that can be used to understand what is a cyber attack. This type of malware encrypts a victim's files and then demands a ransom be paid to decrypt the files. This can be a very costly attack for the victim, as they may not be able to access their essential files unless they pay the ransom. 
4. Spyware: It is a malware designed to collect information about a victim without their knowledge. This information can be used to track the victim or steal their identity. 
5. Wiper malware: It is malware that is designed to delete files or render a system inoperable. This type of malware is often used in attacks where the attacker wants to cause as much damage as possible.

Prevention Tips:

• Use reputable antivirus/antimalware software and keep it up to date.  

2. Social Engineering Attacks

A social engineering attack is any attack where the attacker uses human interaction to trick the victim into doing something that will compromise their security. They are cyber security threats that use deception to trick people into revealing sensitive information or performing an action that they wouldn’t normally do. 

1. Phishing: Phishing is a standard social engineering attack that uses fraudulent emails or websites to lure victims into revealing personal information or clicking on a malicious link. 
2. Malvertising: Malvertising is another type of social engineering attack where the attacker uses online advertising to place malicious code on a website that will redirect visitors to a malware-infected site or download malware onto their system.  
3. Drive-by downloads: Drive-by downloads occur when a victim unknowingly downloads malware by visiting a malicious website or clicking on a malicious ad.  
4. Baiting: Baiting is a social engineering attack where an attacker leaves a USB drive or other type of media containing malware in a public place, hoping that someone will find it and plug it into their computer.  
5. Honey trap: In a honey trap, an attacker uses an attractive person or bait to lure a victim into a compromising situation. 
6. Tailgating or piggybacking: Tailgating or piggybacking is an attack where an attacker follows someone through a door or into a restricted area without them knowing.

Prevention Tips:

• Be cautious of unsolicited emails and phone calls don’t click on links or give out personal information unless you are 100% sure of the source.  

3. Distributed Denial of Service (DDoS)

A distributed denial of service (DDoS) attack is a cyber security threat in which an attacker attempts to make a network or server unavailable by flooding it with requests from multiple computers. 

1. Botnets: DDoS attacks are often carried out by botnets, which are networks of infected computers controlled by a malicious actor. A botnet can send many requests to a target, resulting in the target being overwhelmed and unable to respond to legitimate requests. 
2. Smurf attack: In a smurf attack, the attacker spoofs the IP address of the target to flood it with requests. 
3. TCP SYN flood attack: Here, the attacker sends many SYN requests to the target, resulting in the target's resources being exhausted. 
4. UDP flood attack: It is a type of DDoS attack in which the attacker sends many UDP packets to the target, resulting in the target's resources being exhausted. 

Prevention Tips: 

• Use a firewall and limit incoming connections to known IP addresses if possible.

4. Software Supply Chain Attacks

A software supply chain attack is a cyber security threat in which an attacker inserts malicious code into a legitimate software program. It can occur at any stage of the software development process, from the initial coding to the final product distribution. Once the malicious code is implanted, it can steal sensitive data, cause Denial of Service (DoS) attacks, or even take control of the victim's system.

There are many ways in which an attacker can carry out a software supply chain attack. 

• To compromise a software developer's account and then insert malicious code into the software they are working on. 
• To target a software repository such as GitHub and insert malicious code into a legitimate project. This can be done by creating a fake account and submitting a pull request with the malicious code or gaining access to a maintainer's account and pushing the code directly to the repository. 
• To take control of the victim's system, using it to carry out further attacks or access sensitive data. 

Prevention Tips:  

• Keep your software up to date, and only download programs from trusted sources.

5. Cross-Site Scripting (XSS)

Cross-Site Scripting (XSS) is a type of cyber security threat that involves injecting malicious code into a web page. This can be done by exploiting vulnerabilities in the web application or tricking the user into clicking on a malicious link.

XSS can steal information from the user, such as cookies or session information. It can also be used to inject malicious code into the web page, which can be used to redirect the user to a malicious website or to display ads.

Examples of XSS attacks include: 

1. Injecting malicious code into a web page that is then executed by the user's browser. 
2. Redirecting the user to a malicious website. 
3. Displaying ads on the web page. 
4. Stealing information from the user, such as cookies or session information.

There are two types of XSS attacks: 

• Reflected XSS: This attack occurs when the attacker injects malicious code into a web page that reflects the user. It can happen when the web page takes user input and displays it without first sanitizing it.
• Stored XSS: Stored XSS occurs when the attacker injects malicious code into a web page stored on the server. It can happen when the web page needs to properly sanitize user input before storing it.

Prevention Tips:

• Use a web browser extension or plugin that will filter out malicious scripts – such as NoScript for Firefox.  

6. SQL Injection

SQL Injection is a type of cyber security threat that allows attackers to execute malicious SQL code on a database. This can bypass security controls, access sensitive data, or even delete data. SQL Injection is one of the most common attacks on databases and can be very difficult to detect and prevent.  

There are many different types of SQL Injection attacks, but some of the most common include the following:

1. Blind SQL Injection: It exploits vulnerabilities in a web application that does not correctly validate user input. It can allow attackers to execute SQL code without being able to see the results of their actions. 
2. Error-based SQL Injection: It takes advantage of errors returned by a web application when an SQL query is run. By manipulating the input, attackers can cause the application to return sensitive data they can use to their advantage. 
3. Union-based SQL Injection: This attack takes advantage of the UNION SQL operator to combine the results of two or more SQL queries. It can be used to access data that would otherwise be inaccessible.

Prevention Tips:

• Never insert user input directly into your SQL queries. Always use parameterized queries or prepared statements instead. It will help to ensure that your queries are always executed with the correct data and that no malicious code can be injected into them.  

7. Password attacks 

A password attack is a cyber security threat where an attacker tries to gain access to a computer system or network by guessing the password. 

1. Brute-force password guessing: Here, the attacker tries every possible combination of characters until they find the correct password.  
2. Pass-the-hash attack: In a pass-the-hash attack, the attacker gets hold of the hashed password and uses that to log in without knowing the actual password.  
3. Dictionary attack: It is another type of password attack where the attacker tries common words and phrases that might be used as a password.

Prevention Tips: 

• Use strong passwords that are difficult to guess. Also, never reuse passwords across different accounts, and use a password manager to help keep track of them.

8. Man in the Middle (MitM)

A man-in-the-middle attack (MitM) is a type of cyber security attack where the attacker inserts themselves between the victim and the intended recipient, intercepting communications between the two. The attacker can then eavesdrop on the conversations or modify the messages sent.

An attacker can carry out a MitM attack in a few different ways.

1. Session hijacking: Session hijacking is a MitM attack in which the attacker takes over an active communication session between two parties. The attacker can then eavesdrop on the conversation or alter messages.
2. Replay attack: Here, the attacker intercepts and records a communication between two parties, then replay the recording later to eavesdrop on the conversation or alter messages.
3. IP spoofing: In IP spoofing, the attacker alters the source IP address of a packet so that it appears to come from a different device. This can be used to intercept and change communications.

Prevention Tips: 

• Use SSL/TLS to encrypt your communications. It will ensure that your data is safe from interception by third parties. Additionally, you should be careful about the networks you connect to and only use trusted ones.

9. Advanced persistent attacks 

Advanced persistent threats (APT) are a type of cyber security threat characterized by their sophisticated methods and techniques and their ability to maintain a presence on a system for an extended period to steal sensitive data. APT attacks are often targeted and well-planned and can be challenging to detect and defend against.

1. New account creation: This includes creating new accounts, often using stolen or fake credentials. It gives the attackers a foothold on the system they can use to carry out further activities.
2. Abnormal activity: These include downloading large amounts of data or connecting to unusual services. It can help the attackers to avoid detection and stay under the radar.
3. Backdoor malware: This type of malware allows attackers to access the system remotely and carry out activities without being detected.

 Prevention Tips:

• Keep your software up to date. Attackers often exploit vulnerabilities in outdated software, so by keeping your software up to date, you can make it more difficult for them to succeed.

10. Wireless attacks

A wireless attack is a cyber security threat that explicitly targets wireless networks and devices. These attacks can take many forms, from stealing data and information to disrupting or disabling the network entirely. Wireless attacks are becoming increasingly common as more and more devices and networks rely on wireless technology. As such, it is essential to be aware of the different types of wireless attacks, understand what cyber threat is, and how to protect against them.

Prevention Tips: 

• Use a strong encryption method like WPA2 to protect your wireless network. You should also disable any remote management features that are not absolutely necessary, as these can provide attackers with a way to gain access to your network.

4. Cloud security cyber threat

The use of cloud-based services will continue to grow in popularity, but so will the number of attacks targeting these services. In addition, cloud-based services are often less secure than traditional on-premises solutions, making them an attractive target for attackers.

5. State-sponsored attacks

As nation-states increasingly use cyber warfare as a tool of geopolitical conflict, organizations will be increasingly targeted by state-sponsored attackers. Moreover, these attackers will have the resources and motivation to carry out sophisticated and damaging attacks.

Cyber Security Threats and Their Solutions

Many cyber security threats can compromise the safety and security of individuals, businesses, and governments. The most common hazards include viruses, spyware, and phishing attacks. These threats can lead to the theft of sensitive information, the destruction of data, and the disruption of systems and networks.

There are several ways to protect against these threats with the help of cyber threat monitoring, including antivirus and anti-spyware software, firewalls, and encryption. It is also important to keep systems and software up to date and educate users on how to identify and avoid potential threats.

Using Threat Intelligence for Threat Prevention

Cyber threat intelligence is critical for threat prevention. By understanding the threats that exist and how they work, organizations can take steps to prevent them. This may include implementing security controls, developing policies and procedures, and training employees.

Threat intelligence can also be used to detect and investigate threats. This is done by monitoring for indicators of compromise and analyzing events that have occurred. This information can then be used to understand the threat, its motives, and how to best respond. To understand what threat intelligence is, you must first know about its two main types.

1. UEBA (User and Entity Behavior Analytics) is a type of threat intelligence that identifies anomalous behavior within an organization. This can be used to detect threats as they are happening and take steps to prevent them.
2. SOAR (Security Orchestration, Automation, and Response) is a platform that allows organizations to automate the response to security incidents. This can speed up the response time and improve the efficiency of the response.
