Companies Can Prevent Common IT Security Threats

Cyber attacks are becoming more complicated with time. Attackers are using advanced phishing techniques for fooling employees. Due to this, many companies suffer data breaches. According to a report from the FBI, cybercrimes have increased by 300% after the coronavirus pandemic. Attackers are mostly attacking companies that are only trying to remain afloat during these tough times. Most people are working from their homes. Thus, these remote workers become an easy target for attackers. Attackers know that a sudden shift to remote work simply means that there are many security gaps in every business.

Cybercriminals also know that people are suffering economically and mentally during this pandemic. Thus, it is easy to fool them by using social engineering attacks. They will send a fake email that will state that the government is giving free vaccines. Your employee might end up giving all the important data to these attackers.

Even SMBs need to protect their systems from attackers. Cybersecurity is probably the biggest challenge for SMBs. Most SMBs don’t even know that they are hit by a data breach. Due to this, they face massive revenue loss. Even good security measures won’t help you in protecting your systems. The baseline of good security has shifted due to the current pandemic. Attackers have become more advanced with time. Thus, the definition of good security tactics has changed with time. In this article, we are going to talk about the best security tactics that you can implement. These tactics will help you in protecting your business from cyber risks.

  1. MFA or Multi-factor authentication

Many companies think that MFA is inconvenient. However, it is very important for protecting your business from attackers. MFA will ensure that attackers can’t access your network even after stealing your employee’s credentials.

MFA tools will ensure that only legit users can access your system and network. It is very important for both SMBs and large enterprises. Attackers can easily steal your employee’s password by using a phishing attack. Thus, passwords can’t protect your network from attackers. Also, sometimes your employees might be using simple passwords for accessing their accounts. Thus, even a simple brute force attack is enough to crack into your network.

  1. Update your systems and software

Every system and software will have some weaknesses. These vulnerabilities will act as an entry point for attackers. Thus, it is important to update your systems and software. You should replace all the legacy software that is out-of-support.

Attackers are always looking for vulnerabilities in different software. Similarly, white hat hackers and developers are looking for vulnerabilities. They will release security updates for fixing these vulnerabilities in their software.

Software updates are not limited to laptops and PCs only. You also need to update your OS, software applications, routers, and firmware. This will also include your employee personal devices as they are working from their home. You should ensure that they are only using secure devices for accessing your data.

  1. TDR or Threat Detection and Response

Firewalls will also help you in protecting your network from attackers. It is a simple type of network security system. Firewalls will act as a barrier between your network and devices. It works by controlling and monitoring all the incoming and outgoing data packets. There are various security rules that your data packets need to follow. The firewall will automatically block all the malicious data packets. In simple words, it will act as your network bouncer. Thus, it will decide the data packets that can enter your network.

Modern firewalls have taken this to the next level. These modern firewalls come with in-built TDR tools. Threat Detection and Response (TDR) tools use AI for learning about normal traffic. This will ensure that your modern firewall will learn with time. If something extraordinary happens, then it will alert your network engineers. It will stop the malware from infecting the entire network.

  1. DNS filter

DNS filters are very important for every business. Attackers mostly use compromised websites for injecting malware into systems. Thus, you should use a good DNS filter. A good DNS filter can prevent most security breaches. It will ensure that malware won’t get installed in your employee’s system.

DNA is basically how the internet works. If you are visiting a website, then your browser will first send a DNS query. This query will help your browser in finding the IP address of the website that you want to visit.

A DNS filter will first check if the website is on the list. It will have access to a list of malicious and phishing websites. This will ensure that your employees can’t access phishing websites.

  1. Security training

More than 95% of security breaches happen due to simple human errors. Most employees are working remotely now and it is very important to provide them with sufficient security training. This will ensure that your users can spot phishing emails.

In an ideal situation, your employees should only use your technology for doing their work. Also, they should never share their system with their family members. They should be careful about paper trails like files, notes, and sensitive data.

You should train your employees. This will ensure that they can spot suspicious emails and websites. However, you can’t expect your employees to spot suspicious emails just because they know about the definition of phishing attacks. Experienced MSPs like Bleuwire can help you in conducting interactive security training programs.

Your employees should also know about different modes of communication. Attackers can use a chat message, text, phone call, and emails for targeting your employees. They can pose as a potential client, new employee, a vendor, or sometimes even as CEO.


Attackers are always trying to get into your network. They always want access to your systems and data. Thus, you should consider implementing a layered security system. You can protect your network by implementing a modern firewall, DNS filter, and MFA. If you don’t have access to a good IT team, then you should consider working with an MSP. Experienced MSPs like Bleuwire can help you in protecting your system from attackers. They will help you in training your employees. This will ensure that your network and data are protected from attackers. If you need more information regarding IT security services, then you can contact Bleuwire.
