10 Common Internet Security Threats and How to Avoid Them

Are you running a small business? Did you recently fall victim to a cyber-attack? Are you searching for ways to prevent a similar incident from happening again?

Small businesses lose an average of $80,000 annually to cyber-attacks. In some cases, companies bleed millions after losing precious data to cybercriminals.

Hence, reliable computer security is a must. But knowing the enemy is half the battle won, as the saying goes. Thus, before you invest in any computer security service, you must first identify the different internet security threats that can disrupt your business.

But what exactly are these threats? What are the basic steps you can do to avoid them?

Continue reading below for 10 of the most common forms of IT security threats and how to keep them at bay.

1. Computer Viruses

Computer viruses are the most common among internet security threats out there. Viruses enter your computers by attaching to a host file or a system. Once they enter your computer, they can create damage instantly or remain dormant.

The goal of viruses is to infect your other computers and networked systems.

One of the basic steps to protecting your computers from viruses is by setting up a firewall. This firewall works by blocking external access to your network systems.

A firewall is not 100% foolproof. But it will at least deter or slow down cyber attackers.

2. Malware

Another common security threat to your computer systems is malware or ransomware. Malware attacks your files and will only stop until you pay the cybercriminal a hefty ransom.

Studies reveal that malware affects 32% of all the computers in the world.

The attack starts by infecting your database systems. From there, it will encrypt your data then pose a threat to delete all your files.

One of the first signs of a malware attack is the slowing down of your system. If you notice your computers slowing down for no apparent reason, shut it down first. Disconnect them from the internet then reboot your system.

Thereafter, you can install a security product to scan your system for malware. Furthermore, install reputable antivirus software along with your firewall.

3. Phishing

The main targets of a phishing attack include your usernames, passwords, and credit card information.

They steal valuable data by pretending to be banks and financial institutions, and they can also impersonate reputable websites and even some of your personal contacts.

They use emails or instant messages that look legitimate at first glance. Their messages come with URLs that prompt you to input your personal information. In turn, they’ll steal your credentials and use them to access your accounts.

To keep away from phishing attacks, be mindful of the emails and messages you receive. If you don’t know the sender, think twice before opening the message.

Also, check the content of your emails before opening any links. If you see a lot of misspelled words, then a phishing attack is possible.

Additionally, invest in a total security program that offers protection against phishing attacks.

4. Botnets

Of all the different forms of internet security threats, this is one of the most dangerous. A botnet is similar to malware. However, it involves a network of computers that hackers compromised.

In turn, hackers use it to control the infected computers within the network. What makes it even more dangerous is that hackers can control the network remotely.

Since the end goal of botnets is to force you to pay a ransom, installing a dependable security program is paramount. And if you discover one of your computers carries a botnet, you must remove the software and run an antivirus scan thereafter.

5. Distributed Denial of Service (DDoS)

A DDoS attack looks to overwhelm hosted servers and force them to become inoperable. And if your business involves an eCommerce shop or heavy use of social media, a DDoS attack can be catastrophic.

Hence, the best way of protecting your business from DDoS threats is to have a strong relationship with your internet service provider. This is crucial especially if you’re using small business email hosting.

Furthermore, if you’re using cloud hosting, make sure to check your network protection. For starters, it is wise to invest in dependable options like Microsoft Azure cloud.

6. Trojan Horse

A Trojan Horse is a program that looks legitimate and harmless. But in reality, it is a vector that carries many harmful viruses. Once it gains network access, it can steal sensitive company data.

The most common method for Trojan Horse attacks is through email. The email usually comes with a link or attachment containing the viruses. Once you open the attachment, it automatically downloads malware to your computer.

Apart from installing cybersecurity software, you should update your software regularly. This also includes your security patches.

7. SQL Injection Attack

Another dangerous threat is an SQL injection attack. It uses malicious code to penetrate your weak security systems. Thereafter, it can steal or destroy your valuable data.

Protection against SQL attacks involves updating all your database software. Make sure to update all security patches. Avoid sharing database accounts using different applications or sites.

8. Rootkit

Similar to botnets, a rootkit allows hackers to access your system remotely. They do this by placing a collection of tools on your network. Some of the common forms of rootkit attacks include the stealing of passwords and disabling antiviruses, among others.

Rootkits enter your network if your system security is vulnerable. Thus, the solution is to keep your patches up-to-date.

9. Rogue Security Software

This is a form of malicious software that makes you believe that your computer has a virus. Sometimes, it will fool you into believing that your security measures are old.

In turn, they will offer new updates for your security settings. And once you update using their program, that’s the time the malware can enter your computers.

To avoid this attack, you need a dependable security system. Also, do not download updates from dubious sources. Additionally, update through legitimate sites and channels.

10. APT Threats

As for the APT threat, surreptitiously enter your system through coding. Once the APT is inside your system, it will remain there quietly while stealing your financial information.

APT attacks are difficult to detect. Hence, you must pay attention to unusual patterns in your network activity.
