Network Security Assessments: The ultimate guide you need to know

In today’s world, where things are being developed at a fast rate, attackers have been coming up with new techniques to hack systems and steal data. It is really important to keep the systems updated and constantly checked. If an organization’s network isn’t assessed regularly then it is impossible to keep the network safe. Checking your network security is important and this has to be done in regular time intervals. A Thorough Network security assessment is essential so that the organization detects its weak points and in turn improves its security levels.

This blog aims to highlight the importance of network security assessment and also provides the ultimate guide on network security assessment.

Types of Network Security Assessment

There are two main ways to check network security: vulnerability assessment and penetration tests. These two techniques work together hand in hand.

Vulnerability Assessments – A series of security checks of your company. They look at your network’s security from all angles. These tests are frequently done using automated tools and a report is generated indicating areas where your network can be more vulnerable. This kind of scan detects critical problems and identifies how to make the network safer. It lets you have a good perception of your business network and this can help you to direct your team’s efforts appropriately.

Penetration Testing: Penetration testing is done to give a thorough network check. It is an extended version of vulnerability assessment but it penetrates deeper into the systems network. The process of penetration is done using automated tools and more sophisticated tools to discover potential threats.

A Network security assessment involves both vulnerability assessment and penetration testing side by side. It is also termed VAPT Testing ( Vulnerability Assessment and Penetration Testing). Which discovers all the threats and issues related to one’s network. It is mandatory for firms that cannot compromise their digital assets or network. VAPT testing is done by firms with expertise in cybersecurity and penetration testing.

Different Network Security Devices

Network Security Devices are essential in providing a safe network for the organization. They minimize the risk of potential hacker attacks and these devices include:

1. Firewalls: A layer of security that acts as an initial line of defense before the data is transmitted or received on an organization’s network. There are two types of firewalls, hardware-based and software-based. The sole purpose is to block harmful data entering in the network.

2. Intrusion Detection Systems (IDS): IDS is also known for its detection of abnormal activity in the network. The process is executed by checking for logs and network packets entering the system.

3. Intrusion Prevention Systems (IPS): The main difference between IDS and IPS is the way the abnormal data packets are blocked. IPS not only blocks but also prevents harmful packets from entering into the system. IP addresses are blocked if there is a detection of abnormal activity.

4. Virtual Private Networks (VPNs): A VPNs main objective is to secure an open or a public network. VPNs enable remote users to access the internet or the network of the organization.

5. Proxy Servers: Proxy servers, secure the client-to-server connections in the given network. It filters and blocks harmful sites and ensures privacy for the user.

The above-provided network security devices act as the initial line of defense before anyone can access data from the given network. These devices help minimize the loss of data of the organizations. These also improve the network security of the organization.

Benefits of Network Security Assessment

As there are many advantages to network security assessment, further an audit contributes to the comprehensive security and performance of a business. Here’s a look at these benefits in simpler terms:

Protection from Cyber Threats

A network security assessment will give a better understanding of some of the threats to the network such as identifying the weaknesses and risks of the network.

Following Regulatory Requirements

Several industries, such as banking and IT, have their rules in place with standard levels of security (i.e., GDPR and PCI DSS). Frequent evaluation helps them to reveal the weakest parts of the system’s network. This helps the organization to keep their user’s data safe and protected.

Improvement in Security Posture

Assessments are done to analyze the strength of the security and its current level. Thus it allows the organization to find weak spots in the existing system. These include the implementation of best security testing practices and new software updates as these are essential for the improvement of security posture.

Business Continuity Assurance

Evaluations play a crucial role, as they enable businesses to face risks and overcome challenges. Reduction of incident impact shortens downtime and prevents losses. These losses are avoided which could have resulted from an interruption in normal operations.

Customer Trust Enhancement

Regular security assessments are signs of the company’s dedication to protecting client data from any leakage which then positively impacts clients’ confidence. Without this, a business cannot experience optimum customer relationships which could be a huge disadvantage.
