Understanding the Most Common Cyber Security Threats and How to Defend Against Them

Cyber security is a vital aspect of any business or organization that relies on digital technology. Cyber attacks can cause significant damage to data, systems, reputation, and finances. According to a report by Forbes Advisor, small- and medium-sized businesses (SMBs) are especially vulnerable to cyber threats, as they often lack the resources and awareness to protect themselves effectively.

In this blog post, we will explore some of the most common types of cyber attacks that SMBs face today, and provide some tips on how to defend against them.


Malware is a broad term that encompasses any software or code that is designed to harm a computer, network, or server. Malware can take many forms, such as ransomware, spyware, trojans, worms, keyloggers, bots, and crypto-jacking. Malware can infect a system through various methods, such as phishing emails, malicious downloads, unpatched vulnerabilities, or policy misconfigurations.

Malware can have various effects on a system, such as encrypting data and demanding a ransom for its decryption (ransomware), stealing sensitive information (spyware), opening backdoors for remote access (trojans), spreading to other devices (worms), logging keystrokes (keyloggers), launching distributed denial-of-service (DDoS) attacks (bots) or hijacking computing resources for cryptocurrency mining (cryptojacking).

How to protect yourself:

  • Use reputable antivirus software and keep it updated regularly.
  • Avoid opening suspicious links or attachments in emails or messages.
  • Download software and files only from trusted sources and scan them before opening.
  • Apply security patches and updates to your operating system and applications as soon as they are available.
  • Implement strong password policies and use multi-factor authentication for your accounts.
  • Educate your employees about the risks and signs of malware infection.


Phishing is a type of social engineering attack that involves sending fraudulent emails or messages that appear to come from legitimate sources, such as banks, government agencies, or trusted contacts. The goal of phishing is to trick the recipient into clicking on a malicious link, opening an infected attachment, or providing personal or financial information.

Phishing can lead to various consequences, such as identity theft, account compromise, data breach, or malware infection. Phishing can also be used as a precursor to other types of attacks, such as ransomware or business email compromise (BEC).

How to protect yourself:

  • Verify the sender’s identity and email address before responding to any email or message.
  • Look for signs of spoofing, such as spelling errors, grammatical mistakes, or mismatched domains.
  • Do not click on links or open attachments that you are not expecting or that look suspicious.
  • Do not provide any sensitive information via email or message, such as passwords, credit card numbers, or personal details.
  • Use a spam filter and report any phishing attempts to your email provider or IT department.

Denial-of-service (DoS) attacks

A denial-of-service (DoS) attack is an attempt to overwhelm the resources of a system or network to the point where it is unable to respond to legitimate requests. A distributed denial-of-service (DDoS) attack is a more sophisticated version of this attack that involves multiple compromised devices (bots) that are controlled by a central attacker (botmaster).

DoS and DDoS attacks can cause severe disruption to online services and operations. They can also be used as a diversion tactic for other types of attacks, such as data theft or malware infection.

How to protect yourself:

  • Monitor your network traffic and performance for any unusual spikes or patterns.
  • Implement firewalls and load balancers to filter out malicious traffic and distribute legitimate traffic across multiple servers.
  • Use cloud-based services or third-party providers that offer DDoS protection and mitigation solutions.
  • Have a backup plan and a recovery strategy in case of an attack.

Code injection attacks

Code injection attacks are a type of web application attack that involves inserting malicious code into an input field or parameter that is then executed by the server or browser. Code injection attacks can exploit various vulnerabilities in web applications, such as SQL injection, cross-site scripting (XSS), command injection, or remote file inclusion (RFI).

Code injection attacks can have various effects on web applications and their users, such as accessing or modifying database records (SQL injection), executing malicious scripts on the client side (XSS), running

arbitrary commands on the server-side (command injection) or including malicious files from remote sources (RFI).

Code injection attacks can compromise the security and functionality of web applications and their users, such as accessing or modifying database records, executing malicious scripts on the client side or server side, running arbitrary commands on the server side, or including malicious files from remote sources.

How to protect yourself:

  • Use parameterized queries or prepared statements to prevent SQL injection attacks.
  • Use output encoding or escaping to prevent XSS attacks.
  • Use input validation and whitelisting to filter out malicious characters or commands.
  • Use secure coding practices and frameworks to avoid common vulnerabilities.
  • Use code analysis tools and scanners to detect and fix code injection flaws.

Supply chain attacks

A supply chain attack is a type of cyberattack that targets the software development or distribution process of an organization or its third-party vendors. A supply chain attack involves compromising a trusted source of software or hardware and using it to deliver malicious code or components to the end users.

Supply chain attacks can have a wide impact and affect multiple organizations and customers that rely on the compromised source. Supply chain attacks can also be hard to detect and prevent, as they exploit the trust relationship between the supplier and the consumer.

How to protect yourself:

  • Verify the integrity and authenticity of any software or hardware you acquire from external sources.
  • Use secure communication channels and encryption when transferring data or code between parties.
  • Monitor your network and systems for any anomalous or suspicious activity or behavior.
  • Implement security policies and standards for your suppliers and vendors and conduct regular audits and assessments.
  • Use threat intelligence and information-sharing platforms to stay updated on emerging threats and vulnerabilities.

Insider threats

An insider threat is a type of cyberattack that involves a malicious actor who has legitimate access to an organization’s network or systems. An insider threat can be an employee, a contractor, a partner, or any other authorized user who abuses their privileges to steal, sabotage, or compromise data or assets.

Insider threats can pose a serious risk to an organization’s security, as they can bypass security controls and exploit sensitive information. Insider threats can also be motivated by various factors, such as financial gain, personal grudges, espionage, or ideological beliefs.

How to protect yourself:

  • Implement the principle of least privilege and limit access to data and resources based on roles and responsibilities.
  • Use identity and access management (IAM) tools and solutions to monitor and control user activity and access.
  • Conduct background checks and security awareness training for your employees and contractors.
  • Establish a reporting mechanism and a response plan for any suspected or reported insider incidents.


Cybersecurity is not a one-time effort, but a continuous process that requires constant vigilance and adaptation. By following these cybersecurity best practices for 2023, you can help your organization reduce its exposure to cyber risks and enhance its resilience against cyber threats.

However, no organization can be completely immune to cyberattacks, so it is also important to have a backup plan and a recovery strategy in case of a breach. Having a comprehensive incident response plan, a reliable backup system and a trusted cybersecurity partner can help you minimize the impact and restore normal operations as soon as possible.
