Network security threats and vulnerabilities can come in many forms, but they all have one thing in common: the intent to breach your network and obtain access to data.
Network security is essential because any attack on your network can be detrimental. In the contemporary world, a business that does not want to face a loss needs to understand how to identify network security threats & vulnerabilities.
Companies, especially small businesses, need to understand cybersecurity threats. According to Business Insider, 28% of data breaches occur in small businesses, as these are the most vulnerable ones.
In addition to that, around 60% of businesses become bankrupt six months after undergoing a significant cyberattack or data breach.
How exactly do threats and vulnerabilities differ?
Vulnerabilities are the places where you need to look for when hackers get through.
They’re like weak spots in your systems, and they generally exist because someone overlooked a particular part of the network security area. Threats are things that constantly want to disrupt your network security and your business.
How to identify network security threats and vulnerabilities?
As the world continuously moves into a more digital space, threats are also evolving at a relatively rapid pace.
- Use threat intelligence: In order to identify network security threats and vulnerabilities, we recommend using threat intelligence. Threat intelligence empowers us to take quicker, more data-driven security choices and shift from reactive to proactive behavior in the face of threat actors.
- Constantly monitor your network: It is important to search for any potential signs that can indicate threats and vulnerabilities to your network security. Thus, we strongly recommend constantly monitoring any aspects like atypical activity or sudden changes related to your Internet traffic.
- Keep your software up to date: One of the best ways to protect against threats and vulnerabilities is to make sure your software is always up to date. You can also opt for third-party software to take care of all your network security needs.
What are the main types of threats and vulnerabilities in network security?
It is essential to discuss the most common network security threats to help better identify the network security threats and vulnerabilities. The following are some security threats:
Denial of Service (DoS) Attacks
A Denial of Service attack is an attempt to make a computer or network resource unavailable to its intended users.
There are many forms of DoS attacks, but the most common ones involve flooding the target with requests for service until it can no longer respond to legitimate requests or crashing the system by overwhelming it with malformed or malicious data so that it becomes impossible for anyone outside of this group to engage with any server or application running within their company’s perimeter.
In a DoS Attack, the attacker typically uses a botnet or network of compromised devices to send a large volume of traffic or requests to the target system, overwhelming its resources and rendering it unavailable to legitimate users.
DoS Attacks can have serious consequences, such as disrupting business operations, causing financial losses, and damaging an organization’s reputation. DoS attacks can occasionally serve as a cover for other illicit activities like data theft or malware installation.
Viruses
A piece of code with the potential to multiply and spread is referred to as a virus. One class of malware that has the ability to duplicate itself and spread from one machine to another is viruses.
Once a computer has been infected, a virus can propagate to other networked computers by using the network connection.
Because a viral epidemic may swiftly deplete network resources, this can represent a major danger to network security. Viruses can also be used to perform denial-of-service attacks against network systems.
Advanced Persistent Threats (APTs)
An APT is a type of cyberattack where an intruder gains access to a network and remains there undetected for an extended period of time.
APTs involve a multi-stage process, typically starting with the attackers gaining access to the target network through a variety of means such as spear-phishing emails or malware infections.
Once inside the network, the attackers will use a range of techniques to maintain their access and evade detection, such as using backdoors, rootkits, or remote access tools.
The ultimate goal of APTs is usually to steal sensitive data or intellectual property, disrupt operations, or cause reputational damage to the targeted organization.
APTs can be difficult to detect and mitigate due to their advanced techniques and the fact that they are often highly targeted.
SQL Injection Attacks
Attacks of the sort known as SQL injection allow hackers to run malicious SQL code on a database. Malicious code inserted into an input field used in a SQL query can do this.
The attacker’s code will be performed together with the remainder of the query if the input field is not properly sanitized, giving them the opportunity to view confidential information or perhaps take over the database.
When creating online apps, it’s crucial to follow safe coding procedures to prevent SQL Injection Attacks.
This includes validating user input, using prepared statements or parameterized queries, and sanitizing inputs to prevent malicious code injection.
Regular vulnerability assessments and penetration testing can also help identify potential SQL Injection vulnerabilities in web applications.
Finally, using a web application firewall (WAF) can help detect and block SQL Injection Attacks in real-time.
Phishing
Phishing is the fraudulent act of pretending to be a reliable entity in an electronic contact in order to get sensitive information like usernames, passwords, and credit card numbers.
In order to deceive victims into providing their personal information, phishers frequently build bogus websites or send fraudulent emails that seem just like authentic websites or emails. Once they possess this information, they can exploit it to engage in fraud or identity theft.
As we’ve seen, there are several methods for anyone to jeopardize the security of your network.
