A network can be secure when it has appropriate security measures to keep it from being used for malicious purposes or accidentally damaged by unauthorized users. It means using active and passive devices to block malicious software and other threats entering the network. Passive devices monitor the network for suspicious emails and other activities. If you wonder how to keep your network safe, read on to learn more about these technologies at https://www.fortinet.com/solutions/enterprise-midsize-business/network-security. This article covered some of the basics.
Security management
Security management entails many internal practices that keep the network safe from threats. A security manager manages backup mechanisms, stays updated on software updates, manages user accounts, and monitors system activity. Unfortunately, repetitive tasks are prone to errors. This chapter will outline recommended practices for security management. After reviewing this chapter, consider your network and its security risks. Having the right tools will make the job easier. Security management is crucial for ensuring that your network remains safe from hackers and malware.
Network security management encompasses policies and rules that govern access to network resources. These rules and procedures align with the organization’s mission and goals. To achieve a secure network, first, identify your assets. Then, use an asset tracking system to identify your network assets. For instance, if you have an IP address, you’ll need to add EDR to prevent unauthorized access. Also, consider the least privileged model. It helps to avoid exposing valuable company information to hackers.
Firewalls
There are two kinds of firewalls: the packet layer and the circuit level. Both analyze traffic in the network and look for signs of incidents. The packet layer contains rules that specify which traffic is allowed or disallowed based on source and destination addresses, ports, and service identifiers. The latter is a more secure option but has a higher compute cost. Neither is ideal for every network, but it can be a good solution if you are worried about malware attacks.
The first type of firewall is the traditional one. This one is used to secure networks and prevent unwanted users from accessing them. Typically, malicious software infiltrates the network via email and then spreads to other computers on the network. In some cases, it will also spread to other devices on the network. Therefore, it is essential to keep all devices secure and password-protected. This way, unauthorized users cannot access confidential data or information on a network.
Network segmentation
By separating a network into smaller self-contained parts, you can make it easier to manage and understand the activities within the network. Network segmentation also allows you to control which systems an attacker can access and limit their damage to the network. As a result, a cybersecurity attack will have a lower impact on your network because attackers will be unable to access critical data. This method also prevents an attacker from gaining access to other networks, so you can be sure that you’ll be protected.
The main benefit of network segmentation is that it allows organizations to protect sensitive data and control user access. In addition, it makes tracing the unauthorized use of data and identifying the culprits much easier. Companies that restrict access to users have a strong network segmentation strategy in place. It also makes it easier to determine who is responsible for compromising credentials and other sensitive information. Therefore, it’s important to implement effective network segmentation strategies to help your network become more secure.
Intrusion detection
One of the most important features of intrusion detection systems is their ability to detect and prevent cyber-attacks. Such systems monitor network traffic by comparing it to a baseline, often created by machine learning. As a result, these systems alert IT teams when they detect malicious activity or policy violations. In addition, by using a wide set of rules, these systems can detect novel threats and improve detection accuracy. Listed below are three important reasons to implement intrusion detection systems.
- Host-based Intrusion Detection Systems (HIDS) are installed on each computer in a network. They monitor network traffic and examine each host to detect attacks.
- They also detect malware and other types of malicious activity. While network traffic is a primary attack source, host-based IDSs are also useful for protecting network infrastructures.
- They can identify malicious traffic even if the attack source is internal.
Web security
Today, the web plays a major role in the lives of modern enterprises, and web-based cyberattacks are increasing in frequency and sophistication. As the first line of defense against cyberattacks, web security is critical to business continuity and security. Without effective web security, organizations are vulnerable to sensitive data exposure, costly ransom attacks, reputational damage, and even compliance violations. Here are some things to consider when installing a web security solution.
While large, mature organizations often overlook web application security, these organizations need to protect their web applications. Dedicated web application security solutions are vital for large organizations, where they must secure thousands of web assets. In addition, organizations need to protect sensitive information across multiple systems and geographies. Finally, because web applications are so prevalent today, organizations must invest in a dedicated web application security solution to protect them from cyberattacks.
