What Is The Purpose Of Network Security – The development of the internet and technology is fast. users have more access to digital tools and services than ever before, providing them with a level of information and convenience previously unimagined.

However, along with the rapid development of the internet the number of cyber threats is increasing. From the theft of individuals’ credit card numbers to massive corporate data breaches, the security threats are real, but there are tools in place to keep these attacks at bay. Network security keys are digital measures that help protect internet users when they .

What Is The Purpose Of Network Security

What is a network security key? Basically, it is the password or code required to access a local area network. Most of us are familiar with network security keys – at home, you use one to join your personal Wi-Fi network. Network security keys allow users to establish a secure connection and prevent unauthorized access to the network.

Cloud Security Vs. Network Security: Which Is Best For Your Sme?

For example, diners wishing to visit a website using a restaurant’s local network would likely have to connect using that particular network’s security key. This may include entering a unique password to access the key, which users’ devices can remember every time they try to log into that network.

Users connecting to an airport Wi-Fi network may be required to pay a fee and input personal information. That information is protected thanks to the security protocols in place in the network itself. It would be difficult for those who do not have the required key or password to compromise or attack network user information. Violations still occur, but these keys reduce the likelihood of criminal incidents.

The main benefit of network security keys is to ensure that digital user information is safe. Secure wireless networks help prevent various types of threats, according to the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA). Here are some examples:

Paging occurs when a user connects to an unprotected wireless network or a well-protected wireless network, such as a neighbor’s Wi-Fi network. That neighbor could be able to access and compromise the front end user’s information, or it could attack the network itself. Because people rarely monitor who is logged on to their network, they may not know that hacking is taking place.

What Is A Network Intrusion Protection System (nips)?

Wardrobbing is a more targeted version of hacking where hackers find unprotected or poorly protected Wi-Fi networks in close range. According to CISA, this can include someone driving down the street, connecting to a network, and interfering with the information of other connected individuals.

A malicious twin attack involves a fake network that closely resembles a legitimate one – for example, a Wi-Fi network like the one at a coffee shop, which appears to have the same security protocols as its prevents users from believing that they are involved. the actual coffee shop network. Those users could easily compromise their data.

Wireless sniffing and unauthorized computer access occurs when people seek out weak or unprotected networks and are able to access and compromise sensitive data communicated through and within them, such as credit card numbers entered available for transactions or personal files on a digital device. Often, because people are not actively monitoring who is connected to a network, they are unaware that these activities are taking place.

What Is The Purpose Of Network Security

Shoulder surfing is less sophisticated than other digital risks but just as dangerous. It occurs when someone views the information that another user is inputting on a computer or mobile device. For the user at a coffee shop, a shoulder surfer could figure out a network password or personal information, such as a Social Security number or home address, simply by looking at the information typed into the device.

According to Ars Technica, “[W]hen the original Wi-Fi 802.11 standard was released in 1997, it included WEP – Wired Equivalent Privacy – which ostensibly offers the same privacy expectations that users today expect from wired networks .” This type uses a hexadecimal key, which are 10- or 26-digit keys containing numbers (from 0 to 9) and letters (from A to F), for example, 0FAB571CD5. “Later revisions to WEP provided the ability to automatically hash a human-readable password of arbitrary length into those 10- or 26-digit hexadecimal codes in a way that was consistent between clients and routers,” according to Ars Technica. , WEP keys show vulnerabilities in their encryption and security protocols. With WEP keys, the same encrypted message is provided in every connection, meaning that everyone with access to the same key on a given network has access to each other’s information. Research from Kaspersky notes that WEP keys are commonly used in some parts of the world.

Wi-Fi Protected Access (WPA) keys are seen as an upgrade over WEP because of their ability to accept human passwords and hide user information from others on the same network, as well as authentication codes that make information sent over networks more secure. . “Connecting to a ‘public private’ Wi-Fi network where everyone knows the password no longer meant sharing everything you sent and received with anyone else who happened to be nearby and who know the password,” according to Ars Technica. Just as WPA keys are an upgrade over WEP keys, WPA2 keys offer even more security for network users. According to Lifewire, “WPA2 further improves network security because it requires the use of a stronger encryption method called AES,” or Advanced Encryption Standard. AES works by using block ciphers to encrypt and decrypt data, reports TechTarget.

WPA3 keys go even further in their authentication protocols. Writing in a post for InformationWeek’s Dark Reading, Curtis Franklin Jr. says. that “the main improvement over WPA3 Personal is in the authentication process, where WPA3 makes brute force dictionary attacks much more difficult and time consuming for an attacker.”

However, just because WPA, WPA2, and WPA3 keys are improvements over their predecessors, they do not fully ensure security on a given network. Hackers can still compromise or access keys with a lot of effort and ingenuity. Even users connected to more secure networks can exchange information with others on less secure ones, potentially putting their own security and data at risk. Users should always exercise caution when sharing sensitive information on any connected network.

Network Security Policy: A Definitive Guide

Biometric and Two-Factor keys are similar to WPA and WEP keys in that they work to provide security to users accessing a particular network, but differ in that they require external or two-factor authentication something from them. For example, Yubico provides hardware authentication tools that can help ensure that the person connecting to a network or device is who they say they are. Users can insert YubiKeys into a computer, and are then prompted to press their key for authentication before being granted network access. The additional “physical” or outer layer of this type of two-factor security protocol helps ensure that the network and its connected devices are protected.

Other biometric security features include fingerprint scanning and facial recognition. By providing some form of physical or human identifier, they help ensure that networks remain secure. Still, even with these improved features, security can be compromised. Someone who accesses a network using two-factor authentication can fall prey to a phishing scam, giving private and confidential information to someone who thinks they are a legitimate company or organization.

Likewise, someone accessing a network using two-factor authentication or biometric options may inadvertently download malware or other harmful software that can compromise their information and the security of a larger network. While two-factor authentication and biometric options help keep networks secure, users on those networks should still be aware of the information they’re sharing.

What Is The Purpose Of Network Security

Hackers and cybercriminals can have different intentions when attacking a network. They may want to disclose sensitive corporate data and information. They may want to crash the network itself to stop a person or organization from accessing the internet. Maybe they just want to play pranks. Regardless of the intent, security keys work to deter hackers and criminals.

What Is Network Security? Definition, Types, Attacks & Tools

When people access a network, they often exchange more than usernames and passwords. On a poorly protected or unprotected network, information about people’s identities, including addresses, financial information, employment data and other sensitive data, can be compromised. On a secure network, encryption keys, protocols, and standards help keep that information private.

In 2014, Sony Pictures Entertainment was hacked by a group that not only stole massive amounts of sensitive data, but also temporarily rendered individual users’ devices unusable. Additionally, individuals connected to poorly protected or unprotected networks may inadvertently download spyware or malicious malware that can harm their devices.

Network security keys help ensure that users and their data are kept safe and secure. There are several ways to find network security keys on computers and mobile devices.

Lifewire provides a thorough, easy-to-understand explanation of how to find a network security key on a personal computer. Users can access their particular routers as administrators, then get information about the network ID and paskey, as well as identify connected devices. For users, this can be helpful to find out if the router or network
