Paraphrase and rewrite in own words:

Defending your network is easier if you have the right equipment and software in place. Preventing rogue access points and other unauthorized devices from joining your network is best accomplished by thoroughly inspecting each device that attempts to join your network. External assaults may be thwarted using the following kinds of network security devices, both physical and software: Use of firewalls. It is one's initial line of protection against attacks from other networks when using a firewall device. In addition to being separate systems, firewalls may be part of routers and servers as well. Appliances that act as the principal device separating two networks may include firewalls, which are available in both hardware and software forms. Firewalls block all incoming network traffic that the company does not want. The firewall may entirely block particular or all data, or it may conduct a verification on part or all of the traffic, depending on the organization's firewall policy (Ambhore & Wankhade, 2020) Use of intrusion detection system. This security system works by detecting a intruding hacker or a malicious software like a Trojan virus on a network so that you can use other programs and software to remove it or block it from gaining access. Deploying an IDS can help network administrators identify weaknesses or exploits that a hacker might use to gain access to the system. IDS can be classified as host based IDS, network based and intrusion prevention system. Intruders may be detected and prevented from starting any known attack by an IPS. These systems combine the capabilities of firewalls with intrusion detection systems to protect against cyberattacks. Wireless intrusion prevention and detection system (WIDPS). WIPS is a standalone physical security system or could be an integrated software program that monitors a wireless LAN's radio spectrum in order to detect rogue websites and other wireless security risks and deny them access Use of antivirus. These is the most commonly used line of defense against viral attacks. There are different ways the antivirus software recognize and neutralize malicious software. Based on file length comparisons, based on the known and existing malware signatures and the use of heuristics to identify previously unseen malware (Dyachkov, 2021)
