Network hacking


















You will need a wireless network enabled device such as a laptop, tablet, smartphones, etc. You will also need to be within the transmission radius of a wireless network access point.

Most devices if the wireless network option is turned on will provide you with a list of available networks. If the network is not password protected, then you just have to click on connect. If it is password protected, then you will need the password to gain access. Since the network is easily accessible to everyone with a wireless network enabled device, most networks are password protected.

It was developed for IEEE Its goal was to provide the privacy equivalent to that provided by wired networks. WEP works by encrypting the data been transmitted over the network to keep it safe from eavesdropping. Open System Authentication OSA — this methods grants access to station authentication requested based on the configured access policy. The station encrypts the challenge with its key then responds. If the encrypted challenge matches the AP value, then access is granted.

It is used to encrypt data on It uses temporal keys to encrypt packets. Cracking is the process of exploiting security weaknesses in wireless networks and gaining unauthorized access. There are basically two types of cracks namely;.

WPA uses a pre-shared key or passphrase for authentications. A phishing attack works by sending a link to a user, frequently disguised as a legitimate message, or coming from a legitimate source and getting the user to click on the link so they download malware, command and control executables, or provide their network credentials in a web form.

These attacks are known as malware delivery , command and control , and credential harvesting , respectively. One frequent approach attackers use is spoofing , where the attacker purports to be somebody the recipient knows, such as the CEO or CFO. Use SPF on your email domain to authorize external servers and senders and an email filtering service to prevent users form ever receiving spoofed messages. To protect your network, your employees, and your organization, here are a few general principles you can follow and train your users to follow:.

The principle of least privilege is the security concept that any user, administrator, system, or software should have only the minimum permissions required to perform its function and no more. This approach can be unpopular for users, but it is an essential step to protecting your network form hackers. Giving users only the necessary permissions to perform their jobs protects against unintended system changes that could expose vulnerabilities, accidental changes, and - in the event of an attack - reduces the ease with which hackers can escalate privileges and do damage to your network, data, and organizational reputation.

The principle of least privilege is a simple one, but it should not be taken for granted. Administrators should also play by the same restrictive rules. A good practice for system administrators to follow is to use two accounts, one for their day-to-day work that has no more privileges on the network than a typical user, and one for doing administrative work as needed.

The same principles for managing passwords in Tip 1 above apply here. Where possible, password policies for administrative accounts should be higher than for typical users and multi-factor authentication MFA should be used on all administrative interfaces.

Encryption is a vital part of the Internet and there is good reason for this. Encryption helps keep our data safe from hackers and has been used for decades to secure sensitive information, such as credit card numbers. With massive data breaches, like the recent GoDaddy breach , attackers are creating serious problems across many fields. It is becoming imperative to use strong encryption and other measures to keep your network and domain secure.

As a web developer, DevOps team, IT support, or everyday user of the Internet, you need to be aware of the encryption used by the sites you host and the sites you visit.

Here are a few general principles I have for using strong encryption:. Most modern web browsers will show some visual indicator of an unencrypted site like the one shown below from Microsoft Edge.

Be on the lookout for signs of a site not using strong encryption and steer clear of it. Use the security tools below to look up your website's certificate and ensure that you are using strong encryption. This one is a simple tip - to protect systems from infection, install anti-virus software, ensure that it receives regular software updates and version updates, and schedule anti-virus scans to run on a schedule, on demand, and on file access.

Protecting systems from infection is a top priority in any network security program. When it comes to ensuring computers are safe from malware, anti-virus software provides a good layer of protection on the endpoint.

There are several free anti-virus scanners available that have certain limitations, as well many commercially available, off-the-shelf ones.

Whether you manage a single computer or a fleet of thousands, make sure all your endpoints are protected and stay up to date. Zero-day vulnerabilities can be exploited fast within days or hours , so automating updates to your anti-virus software will help ensure you have the vendor's latest signature updates to identify and protect against new vulnerabilities in the wild.

In addition to the anti-virus software installed on your machines, stay alert to major vulnerabilities disclosed in vendor publications. Be aware of risks in second-party software operating systems , third-party software from software vendors , and fourth-party software from vendors of software vendors at a minimum. Backups are an essential part of disaster recovery, and you should make sure they are encrypted.

Unencrypted backups are vulnerable to information disclosure. If an attacker got their hands on your backups and they were unencrypted, the attacked would have access to your valuable data and any personal information stored within the backups. For this reason, it is important to encrypt your backups and store physical backup media in a secured location.

As a general principle when dealing with company data, you should look for ways to encrypt and secure data in all its states: at rest, in transit, and in use. The best way to protect data is by looking for ways that data can be encrypted while users are accessing the data, while the data are being transmitted or received, and while data are sitting in storage, including in backups. It is often said that sharing is caring but sharing services on a network-connected device are a frequent source of vulnerability.

OmniPeek is included on this list despite being a commercial tool due to the extensive feature set. This tool is intended to be an all-in-one Wi-Fi network management solution and includes packet capture, protocol decoding, network diagnostics and troubleshooting and even playback and analysis of voice and video traffic for diagnostic purposes. CommView for WiFi is another popular wireless monitor and packet analyzer tool.

It comes with an easy-to-understand GUI. It works fine with It captures every packet and displays useful information as a list. You can get useful information like access points, stations, signal strength, network connections and protocol distribution.

This tool is basically for Wi-Fi network admins, security professionals, home users who want to monitor their Wi-Fi traffic and programmers working on software for wireless networks. This tool can also be used to crack different password hashes. Just upload the handshake file, enter the network name, and start the tool. This tool has a huge dictionary of around million words to perform attacks. The tools discussed so far have been focused on wireless hacking from the desktop.

However, the growth of mobile devices has also inspired the creation of several hacking tools designed for smartphones and similar devices.

Kali Linux NetHunter is one example of such an app. It is a fully open-source Android penetration platform that is designed to run on Nexus phones.

Attempting to gain unauthorized access to wireless networks is illegal in most jurisdictions. If you want to practice with these tools, use a wireless network that you own or one where you have the permissions of the network owner. Wireless monitoring and troubleshooting tools are basically for network admins and programmers working on Wi-Fi-based software.

These tools help when some of your systems face problems in connecting to the network. They are also valuable for red teamers and penetration testers looking for potential vulnerabilities to exploit.
