Common Types of Cybersecurity Threats


Businesses of all kinds are vulnerable to cybersecurity threats without sufficient security systems in place. There are many potential threats out there that can put your operations and data at risk, making it important to know about the different threats you might face to help ensure you’re prepared for them.

The following are some of the most common types of cybersecurity threats out there to protect against.

DoS and DDoS Attacks

Two of the most common types of cybersecurity threats include denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks. These two are similar to each other, but there are a couple of key differences to keep in mind.

DoS attacks entail cybercriminals flooding websites with high levels of false traffic to the point where they are unable to handle new requests. Eventually, the website shuts down because of this flood.

Meanwhile, DDoS attacks involve hackers targeting specific devices or networks and using several systems to overload them. These attacks are even more challenging to prevent and mitigate than DoS attacks.

Thankfully, cybersecurity measures such as building a secure network can help prevent both of these critical attacks.


Malicious parties may also attempt to infect systems with different types of malware. For example, you might have your system infected with a computer virus that negatively affects your operations.

One of the most common types of malware that attackers use today is ransomware. This type of attack prevents you from accessing data while threatening to steal or leak it in exchange for a certain amount of money, essentially holding your business hostage until you pay a ransom amount. Attackers often demand cryptocurrency payments because of their untraceable nature.

To avoid malware, it’s important to ensure that you and your staff don’t click on suspicious links in emails and enter data on other websites, download fishy attachments, or provide information to unverified users.

MITM Attacks

Man-in-the-middle (MITM) attacks may also put your systems at risk. These attacks entail hackers making changes to communications between devices and servers. Generally, this involves the attacker imitating the server to which your devices send data, allowing the attacker to collect your data in the process.

A couple of ways to prevent these attacks include using digital certification and sufficient encryption methods.

Phishing Scams

Phishing attempts involve sending emails to recipients that appear to come from a trusted source, such as a friend, colleague, or brand. These emails contain a link to a spoof site that requests users to enter login information, stealing it in the process via keystrokes. Hackers can then use these details to log in, steal data, and make changes to people’s accounts while attempting to phish other users.

The best way to avoid these scams is to ignore emails with links unless you’re certain the email is valid.

SQL Injection Attacks

A structured query language (SQL) injection attack occurs when malicious parties use code to access a specific server that stores information for services or sites using SQL. Hackers can then access and modify any information they collect via SQL databases.

You can avoid these attacks by using strong code and the principle of least privilege (PoLP) to secure all vulnerable SQL databases.
