Common network security issues your business faces

Our reliance on technology grows as it evolves and advances. Because most of our day-to-day business operations are online or accessed through digital tools, we must be ever more vigilant about network security threats than we have ever been before.

If your organisation is familiar with common network issues, you may be able to develop more comprehensive strategies and procedures to protect yourself against them.

SQL injection attacks

Although SQL is principally used to manage relational data, it is also frequently used to retrieve information. SQL injection attacks occur when malicious code is used to obtain sensitive information, modify, or even eliminate it, leading to the potential loss of data integrity and data confidentiality.

Internal security threats

Reports suggest 90% of cyber-attacks are caused by human error. Examples of human error include phishing attacks, careless data sharing, weak passwords, and other issues. When it comes to insider activities that harm your company’s network or sensitive data, you may experience downtime, financial losses, and loss of customer trust.

Distributed denial-of-service (DDoS)

When criminals infect internet-connected devices (such as smartphones and laptops) and turn them into bots, website crashes, malfunctions, or loads slowly occur. Victims’ IP addresses are inundated with requests from bots sent by hackers, resulting in a large volume of internet traffic overloading the website and causing it to go offline. It is challenging to tell whether traffic is legitimate or compromised in these assaults.

Rogue security software

Rogue security programmes mislead companies into believing their IT infrastructure has been damaged by a virus, by sending them fake warning messages from a well-known anti-malware solution. An infected device is infected, and then spam messages are sent to the victim, forcing them to pay for a security solution that doesn’t exist.


A compromised device can be used to collect information about victims through malicious software, which allows malicious actors to mine devices for sensitive data such as bank account details, passwords, or email addresses. This can then be used to commit identity theft, blackmail, or other actions that damage businesses.

Malware can include:

  • Rootkits: An attacker can gain unauthorised access to a system, impersonate authorised users, and fraudulently gain access privileges.
  • Worms: a program that scans vulnerable devices and attempts to exploit them to spread across networks and devices.
  • Trojans: Hackers can exploit legitimate software to bypass a network’s defences, granting them extraordinary access to systems.
  • Spyware: A keylogger may be installed without your knowledge and record personal information such as email addresses, passwords, and credit card numbers.


When ransomware encrypts a victim’s data, it prevents them from accessing their files unless they purchase the decryption key. Ransomware as a service (RaaS) refers to the scenario where ransomware developers provide codes so that customers can develop their malicious malware and launch cyberattacks. BlackMatter, LockBit, DarkSide, and REvil are all examples of RaaS.

Phishing attacks

90% of security breaches are the result of phishing attacks, and social engineering is becoming more of a threat to networks every day. Victims are tricked into clicking on malicious links or downloading malware-laden attachments after receiving emails that appear to be from a trusted entity, which attempt to gain access to networks and steal personal information like credit card information.


Viruses frequently accompany downloadable files from emails or websites to exploit vulnerabilities in your software and infect your computer with malicious code, disrupting network traffic, stealing data, and more.
