Network Security Devices. With the rise of cybercrime, network security has become a top priority for businesses. The good news is that there are now several devices that can help prevent hackers from accessing your data or stealing your identity.
Here are some of the most popular security devices:
Firewall
Intrusion Detection System (IDS)
Intrusion Prevention System (IPS)
Port Security Appliance (PSA)
Wireless Intrusion Detection System (WIDS)
VPN Appliance
Host Intrusion Prevention System (HIPS)
Network-Based Application Recognition (NBAR) Device
I will be discussing only some of these the Network Security Devices.
How does Firewall work?
Firewalls are to protect your computer against unauthorized access to your network or system. They are hardware or software applications that filter and control traffic. Further, to ensure that information does not leak out of your network.
A firewall can be a device or it can be an application that is on your computer. It monitors the incoming and outgoing traffic on your network, checking for suspicious activity. If any activity is suspicious, then it can automatically block it.
Firewalls have several advantages over simple virus protection software, including:
Their ability to monitor traffic as well as viruses, worms and Trojans.
The ability to monitor traffic in real-time, allows you to quickly shut down any suspicious activity before it causes any damage.
How do IDS work? Intrusion Detection System (IDS) work?
Intrusion detection systems (IDS) are to identify attacks and intrusions within a computer system and network before they cause any damage. They monitor the network for suspicious activities such as:
Unauthorized access. A hacker may try to gain unauthorized access by using a variety of tools and applications, including brute force attacks and key loggers. By monitoring these activities, you can take action before any serious damage occurs.
A hacker may try to gain unauthorized access by using a variety of tools and applications, including brute force attacks and keyloggers. By monitoring these activities, you can take action before any serious damage occurs.
Malware Infections. A hacker may try to install malware on your system or network, which could lead to data theft and serious security breaches. An IDS will alert you about possible malware infections so you can take action promptly before any damage occurs.
Port Security Appliance (PSA)
A port security appliance (PSA) is a network device that is to protect your network against unauthorized access.
How does a PSA work?
A PSA is used to monitor and secure network ports, ensuring that only authorized users and services have access to the network. It can also be used to protect your company against attacks, intrusions and unauthorized use of the Internet.
What are a HIPS?
A host intrusion prevention system (HIPS) is a software application that is installed on the computer or server. It is used to protect your computer against malicious attacks, such as viruses and worms. HIPS monitors all incoming and outgoing traffic, checking it for any suspicious activity. If it detects any suspicious activity, then it will automatically block it to prevent any damage from occurring.
How do a HIPS work?
A HIPS is to monitor and protect your network from malicious attacks such as viruses, worms and other malware. It works by monitoring all incoming and outgoing traffic, and checking for any suspicious activity. If it detects any suspicious activity, then it will automatically block it to prevent any damage from occurring.
