According to Norton Security , nearly 60 million Americans have been affected by identity theft. In , it is estimated cybercriminals will be stealing 33 billion records per year. These cyberattacks target everyone, but trends show small businesses are one of the most common targets. Thankfully, there are software and online security measures available to help protect your business from cybercriminals. To help your business be prepared and secure for the coming year, Straight Edge Technology has identified 7 of the top cybersecurity threats for and what your team can do to prevent them.

Keep reading to equip your business with proper cybersecurity for and beyond! Cybersecurity is a bit of a buzzword, and people have different definitions in mind when discussing it. While this definition is a mouthful, it highlights two aspects of cybersecurity not often considered. First, very few people think of the hardware or physical computer components when they think of cybersecurity.

Since the first computers started storing data, thieves have been trying to steal it! And while this was more difficult before the internet, it did occur. Believe it or not, one of the first cyberattacks was more of a game than an attack!

In , Bob Thomas developed a computer program able to travel between connected computers. It was not a significant concern since few malicious programs existed. In , Joseph Popp created one of the first malicious computer attacks. Initially passed by a floppy disk, the program was poorly designed and did not disable the computer. The main thing it did was scramble the names of the files.

Thankfully, programmers combated the virus quickly with the proper computer software. Later in , a second cyberattack started circulating, but this one was not programmed to be malicious. Robert Morris was concerned about how much data was easily accessible on the internet. He saw how much of the data was poorly protected by inadequate security and weak or nonexistent passwords.

To show people how vulnerable the current security was, Morris developed a computer worm that significantly slowed down the internet. Whether Morris expected this kind of damage or not, his point was made - even before the internet was widely available, cyberattacks were both real and dangerous. With virtually everything connected online, cybersecurity has never been more critical.

Sadly, it is still common to hear stories of data breaches. Thankfully, there are many companies actively developing better cybersecurity programs. Microsoft, Apple, and Google are constantly updating the software used on computers, servers, tablets, phones, and other devices.

Governments are also recognizing the investment they need to make to protect their servers and classified data. In , the U. The Department of Defense and Homeland Security use up the majority of this budget.

So, what are some of the most common cyberattacks? Malware is one of the broadest terms when it comes to cyberattacks. It is any malicious form of software designed to harm a computer system. Common malware includes worms, viruses, Trojan horses, and spyware. Malware is commonly distributed through physical hard drives, USB external drives, or internet downloads. It typically requires the victim to produce a payment before the hijacked files and system are unlocked. Ransomware spreads through phishing emails or unknowingly visiting an infected website.

Ransomware is devastating due to the difficulty in recovering affected data. While some victims do choose to pay the ransom, there is no guarantee the hacker will give control of the computer or files back to the victim. Social engineering attacks rely on human or social interaction, not just bots entering a computer through the internet.

And because humans are prone to error, social engineering is the biggest security risk today. Social engineering attacks occur when a hacker tricks someone to give them information or access to software or data. Hackers try to manipulate people into breaking standard security procedures.

One of the most common tactics is to have someone think they are helping someone in need. For example, an attacker may pose as a fellow employee or a family member asking for access to a document, bank account, or sensitive data. Think about it - a properly built IT system can prevent a malware attack, but it cannot stop an employee from giving a password to a hacker posing as a coworker.

Many companies have regular training for employees on how to spot social engineering attacks and strategies. It is also essential for businesses to have guidelines in place when working with sensitive data. For example, a common rule is not allowing employees to share company usernames or passwords electronically. If an employee forgets a password, they should call a coworker instead of emailing them. In its most basic form, phishing occurs when a hacker uses a false identity to trick someone into providing sensitive information, downloading malware, or visiting a site containing malware.

The extensive use of electronic communication, including email, text messaging, instant messaging, and social media accounts. One of the most common phishing attacks targets people through email.

An attacker creates an email looking like it comes from your local bank or the government, and the email asks you to visit a website and enter your username and password. Another common tactic is creating a fake social media account resembling a friend or family member. The hacker then asks for money or data through messaging, and it appears it is your family member or friend asking for a favor. Like other social engineering attacks, having training and guidelines in place is a crucial first step.

Employees should be trained to look for specific phishing patterns and tactics. As a business owner, you should make sure your employees know several tell-tale signs of phishing. For example, emails from fake IRS accounts asking for personal information is a common phishing tactic.

However, the IRS and most businesses in general makes it clear that they communicate through postal mail and NOT through email. If you or an employee receives a sensitive request from a business or a direct message from a social media friend, contact the company or person directly to see if the request is legitimate.

As a small business owner or employee, you know how important your security and data are. Even if you have a dedicated IT service provider, it is still good to know the technology threats your business faces.

As a private business ourselves, we know and understand how important your security is to you and your company. The following are the top 7 cybersecurity threats Straight Edge Technology sees for small and mid-sized businesses in In each section, we also include several practical guidelines your company can implement to reduce your risk and exposure to these attacks.

These 7 cybersecurity threats and their preventions are available to download in PDF format at the end of this article. Some of these threats and their solutions are basic, and others are complex. Working with a managed IT service company helps protect your business from these threats. Even if your company has an IT department, we recommend consulting an outside IT company to ensure you have maximum security.

As mentioned before, phishing is one of the most common cyberattacks due to the high levels of interaction humans have on electronic communication. Straight Edge Technology sees this becoming even more of a threat as email and instant messaging increase in the business world.

Office employees receive hundreds of emails and electronic messages every day. Towards the end of the workday, as minds become tired, humans are susceptible to making bad decisions when tired, and their minds feel overworked. Attackers know this, and some choose this timeframe to bombard employees with fake emails and social media accounts. The ensuing investigation determined these accounts gave the hackers access to sensitive patient medical records and Social Security information.

Thankfully, the hospital did the right thing and contacted all affected patients. It also recognized the need for more training in their employees. What should your company do to protect itself from phishing? First , watch for unusual emails and instant messages. Second , be cautious in clicking links or giving sensitive information, even if it appears legitimate. If in doubt, directly contact the source to make sure they sent the message. And third , install anti-phishing toolbars on internet browsers.

These toolbars alert you to sites containing phishing information. While general phishing often occurs online through emails or web browsing, smishing occurs through SMS text messages on your phone. If the link is clicked, it begins the attack. Why are more attackers turning to SMS-based phishing over traditional email phishing? Many email programs, such as Google or Microsoft Outlook, are smart enough to detect phishing emails and label them as spam.

However, anyone can still get a text message and open a bad link! What should your company do to protect itself from SMS-based phishing? First , never open a link in a text message. Most banks and businesses do not ask for information via SMS message - they call or mail you.

Second , watch for misspellings or generic language. And third , if you think the message is legitimate, call the business directly or go to your online account to give the information. This ensures no valuable data falls into the wrong hands. They involve an email being sent with a message, often stating a security policy has been updated or an account statement is attached.
