Network Security Vulnerability

Cybercriminals are constantly looking for ways to exploit your computer security vulnerabilities. While the motivations of these cybercriminals vary (monetary gain, political motives, or just for fun), they all pose a serious threat to your company.

New types of network cyberattacks emerge all the time, but the fundamentals remain the same. Understanding the broad categories will help you keep track of the bewildering array of techniques criminals employs to break into networks. New application flaws appear on a regular basis, but exploitable bugs have always existed.

In this article, I'll go over the most common types of network vulnerabilities that could jeopardize your system's security in 2021.

Let's define what a network vulnerability is before we get started.

What is Network Security Vulnerability?

A network security vulnerability is a flaw or weakness in software, hardware, or organizational processes that can lead to a security breach if it is exploited by a threat.

This is distinct from a "cyber threat" in that, unlike a cyber threat, computer system vulnerabilities are present on the network asset from the start. Furthermore, they are rarely the result of an attacker's deliberate effort—though cybercriminals will exploit these flaws in their attacks, leading some to confuse the terms.

What Are The Different Types Of Network Vulnerabilities?

Computer security flaws can be classified into a variety of categories based on factors such as where they exist, what caused them, and how they could be exploited. The following are some broad categories of vulnerability types:

  • Vulnerabilities in the Network 

These are flaws in a network's hardware or software that make it vulnerable to outside intrusion. Wi-Fi access points that aren't secure and firewalls that aren't configured properly are two examples.

  • Vulnerabilities in the Operating System 

These are flaws in an operating system that hackers can use to gain access to an asset that the OS is installed on—or to cause damage. Default superuser accounts, which may exist in some OS installations, and hidden backdoor programs are two examples.

  • Vulnerabilities in Humans. 

The human element is the weakest link in many cybersecurity architectures. User errors can easily expose sensitive data, provide attackers with exploitable access points, or cause systems to malfunction.

  • Vulnerabilities in the Process

 Specific process controls can cause some vulnerabilities (or a lack thereof). The use of weak passwords is one example (which may also fall under human vulnerabilities).

Other Network vulnerabilities

  1. Malware is an abbreviation for malicious software, which includes Trojans, and viruses.

Malware (Malicious Software)

Malware, short for malicious software, is a catch-all term for viruses, worms, trojans, and other malicious computer programs used by hackers to cause havoc and gain access to sensitive information.

The following are the most common types of malware:

  • Viruses

  • Ransomware

  • Rootkits

  • Adware & Spyware

  • Logic Bombs

  • Trojans

  • Keyloggers

  • Worms

  • Bots/Botnets

  1. Attacks using social engineering to trick users into disclosing personal information such as a username or password.

The term "social engineering" refers to a wide range of malicious activities carried out through human interactions. It employs psychological manipulation to dupe users into making security errors or disclosing sensitive information.

The following are the most common types of social engineering attacks:

  • Phishing emails

  • Dumpster diving

  • Shoulder surfing

  • Spear phishing

  • Whaling

  • Tailgating

  • Pharming

  • Vishing

  • Spam

  1. Outdated or unpatched software exposes the systems running the application, as well as the entire network.

To reduce vulnerabilities, software developers are constantly releasing new patches to fix bugs and errors. Because some applications have millions of lines of code, vulnerabilities are an unavoidable part of software deployment. As a result, software developers deploy patches to address these vulnerabilities, though patches may also be performance or feature upgrades.
