PROTECT YOUR NETWORK: UNDERSTANDING UNUSUAL TRAFFIC AND HOW TO RESOLVE IT
(1) Introduction:
In this digital age, you may have noticed the phrase “Our systems have detected unusual traffic from your computer network” While facing this message can be frustrating; it functions as a vital warning of potential threats and vulnerabilities in your network. Understanding the causes and identifying solutions are essential for optimizing the efficacy of your network.
This article on nuutan.com will explore the significance of anomalous network traffic, its impact on your network, and effective resolution strategies.
Let’s investigate! What is unusual traffic?
In the context of network security, “unusual traffic” is defined as any activity that doesn’t belong to the typical standards. Such activity could be evidence of botnets, DDoS attacks, or malicious software seeking to access your network illegally. These occurrences can cause serious problems for your network, including the loss of data and a poor user experience.
(2) Potentially causing “unusual traffic”:
There are two potential sources of “unusual traffic” that need to be pin-pointed before they can be dealt with successfully. One probable reason of unusual traffic is a large number of requests coming from a single IP address or a small number of IP addresses. This could be indicative of a botnet assault, in which a group of infected devices form a network that is directed from a command centre. It’s also possible that a Distributed Denial-of-Service (DDoS) attack is to blame, in which numerous infected machines flood our network with requests.
(3) The question is what to do about the abnormal volume of traffic:
To resolve the issue of unusual traffic, it is necessary to implement effective security measures. Ensure the network has strong firewalls and intrusion detection systems in place before proceeding. These monitor incoming and outgoing traffic for abnormalities and function as the first line of defence. In addition, employing traffic filtering techniques, such as blacklisting suspicious IP addresses or instituting CAPTCHA verifications, can assist in the identification and mitigation of potential threats.
Updating and patching the network’s software and firmware on a regular basis is another essential check for preventing abnormal traffic. Insecure vulnerabilities are frequently found in out-dated software. By promptly deploying updates and patches, we can strengthen our network’s defences and reduce the likelihood of unauthorized access or damage.
(4) Understanding the Impact of Unusual Traffic:
To fully understand the impact of unusual traffic on one’s network’s performance, it is essential to analyse the effects of unusual network activity. When our network experiences such traffic, it can result in slower load times, increased latency, and possible disruptions. These effects can notably hamper the user experience, impact customer satisfaction, and possibly lead online businesses to face financial losses.
Furthermore, unusual traffic volumes can harm a site’s position in search results. Websites that are user-friendly and secure are given higher rankings by search engines like Google. Search engine algorithms may raise red flags if a network regularly encounters unusual traffic, causing the website’s rating to drop. The site’s rank and organic traffic can suffer as a result.
In addition, unusual activity on your network might harm your private information. In order to gain access to a network, steal data, or launch more complex attacks, cybercriminals frequently take use of security holes. In order to prevent data breaches and financial losses, it is crucial to keep your network secure from any suspicious activity.
In addition to security and performance concerns, unusual traffic can also impact your network’s bandwidth
