Threats to network security and network attacks

Network attacks and other network security threats are attempts to gain unauthorized access to your IT infrastructure via your network perimeter. They can adversely impact your organization’s operations and lead to productivity, financial, and data loss. This article discusses the most common types of network attacks, why they happen, how network security monitoring tools such as vulnerability scanners can be used against them, and other steps you can take to protect your network from them. Built-in security features in Parallels® RAS can prove effective against network attacks.

What are network attacks?

Network attacks are aimed at getting access to your digital assets illegally, then altering, destroying, stealing, or taking them over. Primarily targeting vulnerabilities in your network perimeter before spreading to other parts of your network, network attacks are divided into two types, namely, active and passive.

Active network attacks seek to gain access to your network so that they can modify, encrypt, damage, or delete your data. Thus, the objective of this type of attack is to harm your data.

On the other hand, passive network attacks try to gain access to your network stealthily and without raising an alarm. Once successful, the attackers, more popularly known as hackers, do not make any alterations to your data and try not to give their presence within your network away. This is to prevent your security team from knowing that they have entered your network. They can continue to access your network and digital assets for weeks, months, or even years until they are flushed out.

Regardless of the attack type, if it takes a while for your team to notice that your network is under attack, considerable damage may be done to your data. The impact may be worse if the attackers can leverage other threat vectors such as malware, ransomware, and software vulnerabilities once they gain access to your network. For example, data stolen from your network may be used in identity theft or credit card fraud, or your network could be used as a malware staging point. Thus, the sooner your team stops an attack, the higher the chances of minimizing damage.

What are the most common types of network attacks?

Threat vectors often exploited in network attacks include:

Why do network attacks happen?

There are myriad reasons that network attacks occur, including:

Can vulnerability scanners prevent network attacks?

A vulnerability assessment of your IT infrastructure is a common technique to assess how vulnerable your network is to an attack. It is commonly performed with a vulnerability scanner, which is software that probes your network for known vulnerabilities using a predefined list of modules.

With its network- mapping and port- scanning features, you can use a vulnerability scanner to discover all devices connected to your network and then run a port scan to detect vulnerabilities in these devices. Your team will then need to address any vulnerabilities found.

A vulnerability scanner is often set up to run only from authorized devices. Thus, it needs to log on to a device before it can conduct its assessment. This prevents its use for an attack against your own network.

How do you protect your business from network attacks?

Due to their impact on your operations, it is imperative to protect your business from network attacks. Aside from vulnerability scanners, your team can implement some best practices to strengthen your network.
