Network Security Threats and Prevention

Introduction

Network security, a branch of cybersecurity, refers to organizations’ policies, procedures, and tools to protect their networks and any network resources or traffic.

Network security is essential for safeguarding assets and equipment essential to corporate operations, reducing the attack surface, and stopping sophisticated attacks. Networks are protected both internally and externally using multilayer security methods. There are vulnerabilities in various places, including end-point hardware, users, software, and data channels. This article will cover Network Security Threats and their prevention.

Network Security Threats

Your organization will be vulnerable to a variety of assaults due to network vulnerabilities, including:

• Thread Hijacking

Attacks that hijack discussion threads use the emails against the user. An attacker may reply to an email thread with a malicious attachment after gaining access to an internal email account.

• Cyberattacks

Cyberattacks are cybercriminals’ actions to harm one or more computer networks or devices. Cyberattacks can carry out nefarious deeds, including taking control of computers, stealing data, or utilizing compromised machines as a launching pad for other attacks. Attackers utilize a variety of ways to carry out cyberattacks, including brute force methods, Denial of Service (DoS), phishing, and the introduction of malware or ransomware.

• Mobile Threats

In terms of mobile threats, COVID-19 was in charge. Due to remote work, both the adoption of mobile devices and fraudulent programs posing as coronavirus-related apps increased significantly.

• Phishing

This internet scamming method aims to get personal information like credit card numbers and login credentials. Phishing attacks use fake email communications that impersonate a trustworthy banking institution, website, or personal contact to appear authentic. It deceives the user into responding to the email with financial and credential information or clicking on a malicious URL.

• Denial-of-Service (DoS)

DoS attacks stop authorized users from using a target website’s data or services. When a hostile attacker floods the website with unwanted traffic, they happen.

DDoS attacks are comparable to DoS attacks but are more challenging to defend against. Attackers use an international network of infected computers to perform DDoS attacks.

• Malware

Malicious software is referred to as malware. Attackers typically utilize it to seize control of the target system, steal important information, or covertly install undesirable apps on the victim’s device. Spyware, worms, and Trojan horses can spread via pop-up ads, infected files, phony websites, or phishing emails.

• Ransomware

Cybercriminals use ransomware, a type of software, to lock the target device and demand payment for its unlocking. It spreads by malicious programs and phishing emails and stops users from starting apps or encrypting files; in certain circumstances, it completely disables the device.

• Vishing

A vishing caller can use social engineering techniques to defeat 2FA, obtain access to credentials and other crucial information, or trick the victim into opening a file or downloading dangerous software.

The threat of vishing to business cybersecurity is on the rise. Vishing attacks were warned against by CISA and the FBI in August 2020. APT organizations and malware campaigns have both employed vishing.

• Rogue Security Software

Malware deceives users into thinking that their security settings are out-of-date or that a virus is on their machine. It requests money for the tool or download and then pushes the user to update security settings or install a security feature. Users unknowingly download real malware onto their devices when they attempt to uninstall the presumed virus.

Network Security for Businesses and Consumers

Network security should be a priority for any company using networked data and systems. Network security can protect assets and data integrity from outside threats while enhancing network performance, streamlining network traffic management, and enabling secure data sharing between staff members and data sources.

Several tools, applications, and utilities are available that can assist users in protecting the networks from intrusion and unneeded downtime. Various network security solutions from Forcepoint ensure that strong network security is implemented throughout the company while centralizing and streamlining frequently difficult operations.

Network Security Policy

Network security policies provide enforcement procedures and describe the procedures governing access to a computer network. A network security policy should also describe the architecture for implementing security controls across the network.

In a network security policy, organizations outline their security measures. These measures are intended to detect and stop dangerous and destructive conduct within the company (also known as insider threats) while preventing unauthorized individuals from accessing the network.

Understanding what services and data exist in the network, who may access them, what security controls are already in place, and the potential effects of exposure are crucial when developing a network security policy. An efficient policy prioritizes important data, uses already installed security measures (like firewalls), and encourages network segmentation.

A hierarchy of access privileges should be established by security policies, with each user only being allowed access to the appropriate resources. Organizations must apply these controls in their IT infrastructures, such as network control and firewall configurations, and include them in their written policies.

Ways to Protect the Company

It is essential to safeguard the business. Here are 5 security precautions one should take.

• Boost Access Control

Security includes access control as a crucial component. Improve access control measures by implementing a strong password system.

• Keep All Software Updated

Ensure the software is updated, including computer operating systems and antivirus programs. Software updates frequently include security vulnerability fixes when they are made available.

• Standardize Software

Ensure the security of the systems by standardizing the software. Ensure that users cannot install software on the system without permission.

Uncertainty about the software installed on the network is a serious security flaw. Assure uniform usage across the board for computers:

• Running system
• Browser
• Playback device
• Plugins

• Use Network Protection Measures

Network security is essential. To maintain the safety of the network and its traffic:

• Putting in a firewall
• Verify the access controls.
• Track probable packet floods with IDS/IPS.
• Network segmentation is used
• Make use of a Virtual Private Network
• Conduct suitable upkeep

• Employee Training

An insider threat can occasionally make an exterior threat successful. The staff may be the weakest link in the data protection chain.

Make sure that the staff is aware of network security. Threats should be obvious to the personnel. They should be aware of who to contact to prevent a security breach.

Conclusion

As the internet grows, network security is a crucial area that is receiving more and more attention. It is important to assess the security threats and internet protocol to determine the required security technology. Security technology consists mostly of software-based and various hardware devices.

Additionally, network security comprises provisions built into the underlying computer network infrastructure and policies adopted by the network administrator to guard against unauthorized access to the network.
