Let me ask you a question: have you ever felt anxious about making online payments with your credit cards? If your answer is yes, don't worry; you're not alone. Many people share your concerns. Security is a major worry for many of us, and the reason we feel uneasy about online payments is the uncertainty regarding the safety of the website. However, as times change, so do things, and now most websites undergo thorough testing to identify issues before they affect real users.
Network security tools now assess normal activities on the network and then look for anything unusual, known as anomalies. Since these tools are based on artificial intelligence, they can perform their tasks effectively.
Types of Network Security
There are several network protection protocols, each requiring its own set of tools. These tools and strategies include:
Using a firewall to help maintain network security.
Reverse firewall - to prevent data loss.
Intrusion prevention systems / SIEMs - detect abnormal behavior on the network that has passed through the protection.
VPN / edge services - protect all on-site resources by routing internet traffic through an external proxy server.
Using endpoints as security monitoring stations to identify malicious activity on the network.
This indicates that there are four effective locations that can be used to monitor network security:
*Off-site with edge service
*Network perimeter with a firewall
*Network through packet sniffing
*Endpoints using EDR software
What You Should Do to Test Network Security
Network testing involves checking network devices, servers, and DNS for vulnerabilities or threats.
Therefore, it is always recommended to follow these guidelines before starting the test:
1- Test the most critical areas first: In terms of network security, publicly exposed areas are critical, so the focus should be on firewalls, web servers, routers, switches, and systems open to large crowds.
2- Update security patches: The system being tested should always have the latest security patch installed.
3- Good interpretation of test results: Vulnerability testing can sometimes yield false positives and may not always identify issues beyond the capabilities of the testing tool used. In such cases, testers should have sufficient experience to understand, analyze, and make decisions based on the results.
4- Awareness of security policies: Testers should be well-acquainted with the security policy or protocol in place, as this will aid in effective testing and understanding what is within and outside the security guidelines.
Best Network Scanning Tools
Here are the top network security tools:
1- SolarWinds
SolarWinds is a SIEM system that scans events on the network and monitors anomalies indicated by a real-time threat intelligence feed. This network security tool extends to all devices connected to the network, collecting all log messages and managing their layout, creating a shared coordination, and these logs are also saved while being analyzed by the tool.
Key Features
- Runs on Windows Server
- Collects system logs
- Searches for suspicious activities
Why We Recommend It?
SolarWinds is an on-premises system that runs on Windows Server, collecting network activity data along with logs from endpoints and then searching through this event information to identify security breaches. The tool can also execute automated responses in coordination with other systems.
The message verification service receives direct reporting information from all points on the system, while processing these logs, the "Security Event Management" looks for signs of intrusion or any other malicious activity. Some typical attacks can be detected by looking at a single event, while others only become apparent through a pattern of seemingly unrelated incidents. Therefore, to provide comprehensive network security service, the tool works on both live data and historical logs.
To reduce "false positive" reporting, the Security Event Manager maintains a record of normal traffic patterns and activities. This is an AI-based machine learning technique known as User and Entity Behavior Analytics (UEBA).
In addition to detecting suspicious activity, the Security Event Manager can execute shutdown actions, taking the form of blocking communications from specific IP addresses or suspending a user account that appears to have been compromised.
Who Is It Recommended For?
This is a solution for large enterprises. The tool can collect logs from cloud services but focuses more on on-premises systems, such as networks. You should already have access management tools and firewalls on your network and endpoints, and the SolarWinds system interacts with them.
Pros:
- Log-based SIEM
- User behavior analytics.
- Anomaly detection.
Cons:
- No SaaS version
2- Intruder
This is a cloud-based security tool that conducts continuous vulnerability scans on the monitored system. Upon registration, Intruder performs a comprehensive scan of the system, highlighting security issues. After that, the service immediately re-scans the monitored system whenever it receives updated threat information, ensuring an immediate response to emerging threats, allowing for proactive scanning and continuous monitoring instead of relying on a once-a-month update schedule.
Key Features
- Cloud-based.
- Vulnerability scanning.
- Reduces attack surface.
Why We Recommend It?
Intruder is a cloud-based service that scans networks externally and internally to discover security vulnerabilities. The extent and frequency of scans you receive depend on the plan you choose. This system can detect misconfigurations on network services, gateways, and endpoints and help you fix them.
Threat updates trigger new scans automatically, ensuring continuous monitoring. It is important to note that while new devices or software in the system may not be automatically detected, the platform mitigates this by proactively monitoring the network and automatically running vulnerability and network scans, saving valuable time for technical teams and ensuring timely detection of network changes.
Who Is It Recommended For?
The three plans for the Intruder service make the system accessible to businesses of various sizes; however, the cheapest plan may still be too expensive for small companies. The cloud-based scanner provides external scanning, but you can upgrade to a higher plan to also get scans within your network.
Pros:
- Choice of regular or monthly scans.
- Emergency scans upon detecting a new threat.
- Customizable rules.
Cons:
- You will need the best plan for complete protection.
3- ManageEngine Vulnerability Plus
Vulnerability scanning is a crucial preventive task for network security. There are many ongoing maintenance tasks that network managers need to perform, some of which are essential for keeping the system secure.
Key Features
- Get details on why web server security flaws exist, their impact, and how to fix them.
- Security configuration management.
- Identify real risks from a large number of vulnerabilities.
Why We Recommend It?
ManageEngine Vulnerability Plus is a close competitor to Intruder. This package provides a vulnerability scanning tool and a patch manager to update outdated software identified by the scanner. It can also automatically fix configuration issues and can run continuously without any additional cost.
In addition to vulnerability scans, you need to keep all operating systems patched and apply software updates, as these patches and updates are often written to address newly discovered exploits. ManageEngine Vulnerability Manager Plus includes a patch manager to maintain your software security. It also has a configuration manager that unifies network device settings and blocks unauthorized changes.
Vulnerability Manager Plus combines vulnerability scanning with tools to address the issues identified by the scan, and it also includes access rights analysis and features for <a href="https://3almalt9nia.com/%d8%aa%d8%ad%d9%85%d9%8a%d9%84-%d8%a8%d8%b1%d9%86%d8%a7%d9%85%d8%ac-%d8%a5%d8%af%d8%a7%d8%B1%d8%
