Password-protected services that are listening on an open port require organizations to protect the passwords used to authenticate services on these ports. Aside from never using cleartext protocols, this point emphasizes the need to have strong password policies that prevent weak, breached, or easily guessable passwords.
Last, but perhaps the most important, make sure the underlying technologies and systems listening and answering on the open port are fully patched, and security updates are applied as soon as possible. Attackers often look for unpatched vulnerabilities to compromise an open port. In addition to the strategies mentioned above for protecting open ports, auditing, and other cybersecurity strategies, businesses must enforce strong passwords and use strong password policies.

While MAC addresses are pre-assigned to ethernet devices, theycan be changed with a driver on most current hardware. But since fewpeople change their MAC address (or even know they have one), manynetworks use them for identification and authorization purposes. Forexample, most wireless access points provide a configuration optionfor limiting access to a certain set of MAC addresses. Similarly,some paid or private networks will force you to authenticate or payafter you connect using a web form. Then they will allow you accessto the rest of the network based on your MAC address. Given that itis generally easy to sniff MAC addresses (they must be sent in everyframe sent and received), and then to spoof that MAC to gainunauthorized access to the network, this form of access control israther weak. It is also only effective at the edges of a network,since an end-host's MAC address is replaced when traversing arouter.
The story starts with Michael and Demetris performing anNmap scan which shows that they arestuck on a heavily filtered network. They can reach somecorporate servers, but not any of the (potentially vulnerable) desktopclient machines which have to exist somewhere on the network. Perhaps they are on arestricted conference room or lobby network, or maybe a wirelessaccess point set up for corporate guests. Some of the discovered hosts and networksare shown in Example 10.10. A few details in thisstory (such as IP addresses) have been changed for confidentialityreasons. I will call the target corporation Megacorp.
Long ago the networking community reached consensus that sourcerouting is more trouble (particularly for security) than it isworth. Many (if not most) routers are configured to drop sourcerouted IPv4 packets, so some folks have considered the problem fixedsince the early 90's. Yet source routing, like SYN flooding andTelnet password sniffing, continues as a rare but potentrisk. Demetris tests this attack by ping-scanning files2(10.10.6.30) using packets loose-source-routed through the 10.10.6.60 mail server.Results are shown in Example 10.14.
Please can someone help me out l just acquired hp printer and I'm to used to print using wireless wifi direct it keeps on asking me for a password and I have used the default password of 12345678 but is not connecting and and printed the networks configuration report no default password given.
Top 25 Best Kali Linux Penetration Testing Tools (Pros and Cons). Penetration testing (also known as pentesting) is a handy way of detecting vulnerabilities and weaknesses in IT systems. When using the right tools, penetration testing helps you in improving the quality and security of your crucial applications and systems. Therefore, you can pen test applications, wireless systems (Wi-Fi), cloud infrastructure, system passwords, and more.
First place on this list of Top 25 Best Kali Linux Penetration Testing Tools is John the Ripper. Well, it is a feature rich penetration testing tool used as a password cracker. Free, open-source tool used to crack passwords and audit overall system security. In essence, this tool combines numerous password cracking modes. Besides, you can configure it to meet individual penetration testing needs.
Pentesters use John the Ripper to detect weak system passwords and gain access to databases and applications. It tests the strength of your passwords and other vulnerabilities that hackers can exploit. John the Ripper can perform comprehensive password tests using both dictionary and brute force attacks.
This tool has both raw and hashed passwords. To crack a password, John the Ripper identifies all potential passwords in a hashed format. It then matches the hashed passwords with the original hashed password to find a suitable match. If it finds a match, this tool displays the cracked password in its raw form.
Responder works by imitating several services and offering them to the network. It tricks the Windows systems into communicating via the provided service. The responder then responds to the request, picks the username and password, and hashes them. By prompting users for credentials and gaining clear text passwords, Responder helps you detect key system weaknesses.
Hydra is a Kali Linux login and password cracker. This tool leverages multiple protocols to perform brute force attacks on systems. The Hydra login cracker is parallelized, highly versatile, and easy to integrate. Hydra comes installed on Linux and has both GUI and command line versions.

Password strength is a measure of the effectiveness of a password against guessing or brute-force attacks. In its usual form, it estimates how many trials an attacker who does not have direct access to the password would need, on average, to guess it correctly. The strength of a password is a function of length, complexity, and unpredictability.[1] 2ff7e9595c
