What is a Network Security Evaluation?

Network security is crucial for all businesses. It's the shield that protects our data from cyber threats.

But how do we know if our shield is strong enough? This is where a network security evaluation comes in.

A network scan or evaluation is an important process for evaluating the performance of your network. It involves measuring the performance of physical and logical components of a network, such as servers, routers, switches, data links, and other elements within a network infrastructure. Evaluation of these components helps to identify problems that can cause decreased performance or threats that may compromise the security.

What happens during the evaluation?

Network security evaluation is a systematic process. It involves assessing the security measures in place to protect a network from threats. This process is not a one-time event. It's a continuous cycle of evaluation, improvement, and re-evaluation. It's about staying one step ahead of the cybercriminals.

The evaluation process includes several steps. These range from identifying assets and assessing risks to conducting vulnerability scans and security reviews.

Asset identification and valuation
Risk assessment and threat identification
Vulnerability scanning

The Network Security Evaluation Process

The network security evaluation process is a systematic approach. It involves several steps, each designed to assess a different aspect of network security. The process begins with identifying and valuing the assets on your network. It then moves on to assessing risks and identifying threats. Next, the process involves scanning for vulnerabilities in your network. This is followed by a detailed security review and analysis. The process concludes with threat detection and response planning. Finally, a security audit is conducted to ensure compliance with security standards and regulations. Each step in the process is crucial. Together, they provide a comprehensive evaluation of your network's security posture.

Step 1: Asset Identification and Valuation

The first step in the network security evaluation process is asset identification and valuation. This involves identifying all the assets on your network. Assets can include hardware, software, data, and even people. Each asset is then assigned a value based on its importance to the organization. This step is crucial as it helps to prioritize risks. It ensures that the most valuable assets receive the highest level of protection.

Step 2: Risk Assessment and Threat Identification

The next step is risk assessment and threat identification. This involves identifying potential threats and vulnerabilities that could impact your network. Threats can come from a variety of sources. These include cybercriminals, insider threats, and even natural disasters. Identifying these threats helps to guide your security strategy. It ensures that your defenses are tailored to the specific risks your network faces.

Step 3: Vulnerability Scanning

Vulnerability scanning is the third step in the process. This involves using automated tools to scan your network for vulnerabilities. These vulnerabilities could be exploited by attackers to gain unauthorized access to your network. Identifying them is the first step towards fixing them. Vulnerability scanning should be conducted regularly. This ensures that new vulnerabilities are identified and addressed as soon as possible.

Step 4: Security Review and Analysis

The fourth step is a security review and analysis. This involves a detailed evaluation of your current security measures. The review assesses the effectiveness of your security controls. It identifies areas where improvements can be made. The analysis also includes a review of your network's architecture. This can reveal structural weaknesses that could be exploited by attackers.

Step 5: Threat Detection and Response Planning

Threat detection and response planning is the fifth step. This involves monitoring your network for signs of a cyber attack. Effective threat detection requires a combination of automated tools and manual analysis. It's about catching threats before they can cause damage. Response planning involves developing a plan for responding to a security incident. This ensures that you're prepared to respond quickly and effectively when a threat is detected.

Step 6: Security Audit and Compliance Review

The next step is a security audit and compliance review. This involves a formal review of your network's security. The audit checks for compliance with security standards and regulations. It also assesses the effectiveness of your security controls. The compliance review ensures that your network is in line with industry best practices. It helps to identify areas where improvements can be made.

Creating Actionable Reports and Implementing Changes Based on the Data Collected:

The final step in a network security evaluation is creating actionable reports. These reports should clearly outline the findings of the evaluation, including any identified risks or vulnerabilities. These reports can then be used to implement changes to your network security measures. This could involve patching vulnerabilities, updating security policies, or implementing new security technologies. By creating actionable reports and implementing changes, you can ensure that your network remains secure against potential threats.

Is a Network Scan safe?

Network scans or evaluations are safe and secure processes if done by a trusted and legitimate IT services firm. Before you let anyone near your network, make sure they have provided a document that should be signed by both your company and the company providing the evaluation. We provide a Network Evaluation SOW and NDA to all companies before we will complete any work. This is an important and necessary step that ensures both companies are protected and understand their risks, what steps will take place and what will be provided once the assessment is done. By measuring the performance of individual components, any potential issues that could lead to decreased performance or security breaches are identified before they occur. Furthermore, the data collected during these evaluations can be used for further analysis, such as examining trends in network usage or identifying areas of optimization and risk.

Can you find out if someone has hacked into your network?

Yes, it is possible to tell if someone has hacked into your network through a network scan and evaluation. Some of the telltale signs we could find would be unusual or suspicious activity on the network, like an increase in traffic or data transfer rates, unexpected changes to firewall settings, or unexpected files being added or deleted. It's not always a guarantee that if someone has hacked into your network we would be able to find out but most of the time we can.

Tools and Techniques for Network Security Evaluation

A variety of tools and techniques are used in network security evaluation. These range from automated tools to manual expert analysis by security experts like us. Automated tools are software applications that can scan your network for vulnerabilities. They can identify potential threats and provide detailed reports on their findings. Some of the most commonly used automated tools include vulnerability scanners, intrusion detection systems, and security information and event management (SIEM) systems. These tools can provide valuable insights into your network's security posture. We use a variety of tools to monitor, detect and prevent intrusion on our own network and our client networks. Automated tools are not enough on their own. They need to be complemented by manual expert analysis to provide a comprehensive evaluation of your network's security.

Automated Tools vs. Manual Expert Analysis

Automated tools are a crucial part of network security evaluation. They can quickly scan large networks and identify potential vulnerabilities. However, they are not infallible. They can sometimes miss vulnerabilities or generate false positives. This is where we come in. We are certified security professionals that can provide a deeper level of analysis. We can interpret the results from automated tools, identify false positives, and uncover vulnerabilities that the tools may have missed.

Penetration Testing and Ethical Hacking

Penetration testing and ethical hacking are key techniques used in network security evaluation. They involve simulating cyber attacks on your network to identify vulnerabilities. Penetration testing is a controlled process. It's conducted by security professionals who follow a strict methodology to ensure that the test does not cause any damage. Ethical hacking, on the other hand, involves simulating the tactics used by cybercriminals. The goal is to identify vulnerabilities that could be exploited in a real attack. Both techniques provide valuable insights into your network's security. They can help to identify vulnerabilities that might otherwise go unnoticed.

Case Studies and Real-World Examples

To better understand the importance and process of network security evaluation, let's look at some real-world examples of companies we have worked with and performed cybersecurity evaluations for. These case studies highlight the benefits of a comprehensive network security evaluation and how it can help organizations overcome security challenges.

Case Study 1: Successful Network Security Evaluation

A mid-sized financial institution in Dublin Ohio, worked with us so we could perform a network security evaluation to assess their security posture. We identified several vulnerabilities in their network, which we were able to patch before they could be exploited. The evaluation also revealed critical gaps in their security policies and procedures. As a result, they were able to update their policies to better protect their network and data. We also found that their security camera company had left a port open allowing anyone in the world to access their security camera's server. We did a full email security audit and found several of their employees that had reused their company domain for known malicious sites, had weak passwords and had disabled their MFA. Not only did we find gaps and help them remediate them, we also helped them achieve the compliance that they were required to have.

Case Study 2: Overcoming Security Challenges

A healthcare organization in Ohio faced significant security challenges due to the sensitive nature of their data. They didn't have the expertise to know what their current level of security lacked. We worked with them and conducted a network security evaluation to identify potential threats and vulnerabilities. The evaluation revealed several high-risk vulnerabilities, which we were able to address promptly. We found patches that hadn't been applied to their servers, a number of private file shares that were being accessed by employees that weren't supposed to have access to. We also found that a vendor they used to transmit X-rays to had access to their systems and a very weak password without MFA. They also implemented a continuous monitoring program to detect and respond to threats in real time.

As the cyber threat landscape evolves, so too must your network security measures. Regular evaluations can help you stay ahead of potential threats and vulnerabilities.
